PATCH 1/279 vlan: fix memory leak in vlan_newlink()

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Eric Dumazet <[email protected]>

commit 72a0b329114b1caa8e69dfa7cdad1dd3c69b8602 upstream.

Blamed commit added back a bug I fixed in commit 9bbd917e0bec ("vlan: fix memory leak in vlan_dev_set_egress_priority")

If a memory allocation fails in vlan_changelink() after other allocations succeeded, we need to call vlan_dev_free_egress_priority()
to free all allocated memory because after a failed ->newlink() we do not call any methods like ndo_uninit() or dev->priv_destructor().

In following example, if the allocation for last element 2000:2001 fails, we need to free eight prior allocations:

ip link add link dummy0 dummy0.100 type vlan id 100 \

	egress-qos-map 1:2 2:3 3:4 4:5 5:6 6:7 7:8 8:9 2000:2001

syzbot report was:

PATCH 2/279 clockevents/drivers/i8253: Fix stop sequence for timer 0

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: David Woodhouse <[email protected]>

commit 531b2ca0a940ac9db03f246c8b77c4201de72b00 upstream.

According to the data sheet, writing the MODE register should stop the counter (and thus the interrupts). This appears to work on real hardware, at least modern Intel and AMD systems. It should also work on Hyper-V.

However, on some buggy virtual machines the mode change doesn't have any effect until the counter is subsequently loaded (or perhaps when the IRQ next fires).

So, set MODE 0 and then load the counter, to ensure that those buggy VMs do the right thing and the interrupts stop. And then write MODE 0 *again* to stop the counter on compliant implementations too.

Apparently, Hyper-V keeps firing the IRQ *repeatedly* even in mode zero when it should only happen once, but the second MODE write stops that too.

Userspace test program (mostly written by tglx):

PATCH 3/279 sched/isolation: Prevent boot crash when the boot CPU is nohz_full

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Oleg Nesterov <[email protected]>

Documentation/timers/no_hz.rst states that the "nohz_full=" mask must not include the boot CPU, which is no longer true after:

08ae95f4fd3b ("nohz_full: Allow the boot CPU to be nohz_full").

However after:

aae17ebb53cd ("workqueue: Avoid using isolated cpus' timers on queue_delayed_work")

the kernel will crash at boot time in this case; housekeeping_any_cpu() returns an invalid CPU number until smp_init() brings the first housekeeping CPU up.

Change housekeeping_any_cpu() to check the result of cpumask_any_and() and return smp_processor_id() in this case.

This is just the simple and backportable workaround which fixes the symptom, but smp_processor_id() at boot time should be safe at least for type == HK_TYPE_TIMER, this more or less matches the tick_do_timer_boot_cpu logic.

There is no worry about cpu_down(); tick_nohz_cpu_down() will not allow to offline tick_do_timer_cpu (the 1st online housekeeping CPU).

[ Apply only documentation changes as commit which causes boot
crash when boot CPU is nohz_full is not backported to stable kernels - Krishanth ]

[ strip out upstream commit and Fixes: so tools don't get confused that
this commit actually does anything real - gregkh]

PATCH 5/279 fbdev: hyperv_fb: iounmap() the correct memory when removing a device

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Michael Kelley <[email protected]>

[ Upstream commit 7241c886a71797cc51efc6fadec7076fcf6435c2 ]

When a Hyper-V framebuffer device is removed, or the driver is unbound from a device, any allocated and/or mapped memory must be released. In particular, MMIO address space that was mapped to the framebuffer must be unmapped. Current code unmaps the wrong address, resulting in an error like:

[ 4093.980597] iounmap: bad address 00000000c936c05c

followed by a stack dump.

Commit d21987d709e8 ("video: hyperv: hyperv_fb: Support deferred IO for Hyper-V frame buffer driver") changed the kind of address stored in info->screen_base, and the iounmap() call in hvfb_putmem() was not updated accordingly.

Fix this by updating hvfb_putmem() to unmap the correct address.

Fixes d21987d709e8 ("video: hyperv: hyperv_fb: Support deferred IO for Hyper-V frame buffer driver")

PATCH 7/279 netfilter: nft_ct: Use __refcount_inc() for per-CPU nft_ct_pcpu_template.

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Sebastian Andrzej Siewior <[email protected]>

[ Upstream commit 5cfe5612ca9590db69b9be29dc83041dbf001108 ]

nft_ct_pcpu_template is a per-CPU variable and relies on disabled BH for its locking. The refcounter is read and if its value is set to one then the refcounter is incremented and variable is used - otherwise it is already in use and left untouched.

Without per-CPU locking in local_bh_disable() on PREEMPT_RT the read-then-increment operation is not atomic and therefore racy.

This can be avoided by using unconditionally __refcount_inc() which will increment counter and return the old value as an atomic operation. In case the returned counter is not one, the variable is in use and we need to decrement counter. Otherwise we can use it.

Use __refcount_inc() instead of read and a conditional increment.

PATCH 8/279 ice: fix memory leak in aRFS after reset

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Grzegorz Nitka <[email protected]>

[ Upstream commit 23d97f18901ef5e4e264e3b1777fe65c760186b5 ]

Fix aRFS (accelerated Receive Flow Steering) structures memory leak by adding a checker to verify if aRFS memory is already allocated while configuring VSI. aRFS objects are allocated in two cases:
- as part of VSI initialization (at probe), and
- as part of reset handling

However, VSI reconfiguration executed during reset involves memory allocation one more time, without prior releasing already allocated resources. This led to the memory leak with the following signature:

PATCH 9/279 net: dsa: mv88e6xxx: Verify after ATU Load ops

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Joseph Huang <[email protected]>

[ Upstream commit dc5340c3133a3ebe54853fd299116149e528cfaa ]

ATU Load operations could fail silently if there's not enough space on the device to hold the new entry. When this happens, the symptom depends on the unknown flood settings. If unknown multicast flood is disabled, the multicast packets are dropped when the ATU table is full. If unknown multicast flood is enabled, the multicast packets will be flooded to all ports. Either way, IGMP snooping is broken when the ATU Load operation fails silently.

Do a Read-After-Write verification after each fdb/mdb add operation to make sure that the operation was really successful, and return -ENOSPC otherwise.

PATCH 10/279 netpoll: hold rcu read lock in __netpoll_send_skb()

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Breno Leitao <[email protected]>

[ Upstream commit 505ead7ab77f289f12d8a68ac83da068e4d4408b ]

The function __netpoll_send_skb() is being invoked without holding the RCU read lock. This oversight triggers a warning message when CONFIG_PROVE_RCU_LIST is enabled:

net/core/netpoll.c:330 suspicious rcu_dereference_check() usage!

netpoll_send_skb
netpoll_send_udp
write_ext_msg
console_flush_all
console_unlock
vprintk_emit

To prevent npinfo from disappearing unexpectedly, ensure that __netpoll_send_skb() is protected with the RCU read lock.

Fixes 2899656b494dcd1 ("netpoll: take rcu_read_lock_bh() in netpoll_send_skb_on_dev()")

PATCH 11/279 Drivers: hv: vmbus: Dont release fb_mmio resource in vmbus_free_mmio()

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Michael Kelley <[email protected]>

[ Upstream commit 73fe9073c0cc28056cb9de0c8a516dac070f1d1f ]

The VMBus driver manages the MMIO space it owns via the hyperv_mmio resource tree. Because the synthetic video framebuffer portion of the MMIO space is initially setup by the Hyper-V host for each guest, the VMBus driver does an early reserve of that portion of MMIO space in the hyperv_mmio resource tree. It saves a pointer to that resource in fb_mmio. When a VMBus driver requests MMIO space and passes "true" for the "fb_overlap_ok" argument, the reserved framebuffer space is used if possible. In that case it's not necessary to do another request against the "shadow" hyperv_mmio resource tree because that resource was already requested in the early reserve steps.

However, the vmbus_free_mmio() function currently does no special handling for the fb_mmio resource. When a framebuffer device is removed, or the driver is unbound, the current code for vmbus_free_mmio() releases the reserved resource, leaving fb_mmio pointing to memory that has been freed. If the same or another driver is subsequently bound to the device, vmbus_allocate_mmio() checks against fb_mmio, and potentially gets garbage. Furthermore a second unbind operation produces this "nonexistent resource" error because of the unbalanced behavior between vmbus_allocate_mmio() and vmbus_free_mmio():

[   55.499643] resource: Trying to free nonexistent
			resource <0x00000000f0000000-0x00000000f07fffff>

Fix this by adding logic to vmbus_free_mmio() to recognize when MMIO space in the fb_mmio reserved area would be released, and don't release it. This filtering ensures the fb_mmio resource always exists, and makes vmbus_free_mmio() more parallel with vmbus_allocate_mmio().

Fixes be000f93e5d7 ("drivers:hv: Track allocations of children of hv_vmbus in private resource tree")

PATCH 13/279 netfilter: nf_conncount: Fully initialize struct nf_conncount_tuple in insert_tree()

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Kohei Enju <[email protected]>

[ Upstream commit d653bfeb07ebb3499c403404c21ac58a16531607 ]

Since commit b36e4523d4d5 ("netfilter: nf_conncount: fix garbage collection confirm race"), cpu and jiffies32 were introduced to the struct nf_conncount_tuple.

The commit made nf_conncount_add() initialize conn->cpu and conn->jiffies32 when allocating the struct.
In contrast, count_tree() was not changed to initialize them.

By commit 34848d5c896e ("netfilter: nf_conncount: Split insert and traversal"), count_tree() was split and the relevant allocation code now resides in insert_tree().
Initialize conn->cpu and conn->jiffies32 in insert_tree().

PATCH 14/279 ipvs: prevent integer overflow in do_ip_vs_get_ctl()

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <[email protected]>

[ Upstream commit 80b78c39eb86e6b55f56363b709eb817527da5aa ]

The get->num_services variable is an unsigned int which is controlled by the user. The struct_size() function ensures that the size calculation does not overflow an unsigned long, however, we are saving the result to an int so the calculation can overflow.

Both "len" and "get->num_services" come from the user. This check is just a sanity check to help the user and ensure they are using the API correctly. An integer overflow here is not a big deal. This has no security impact.

Save the result from struct_size() type size_t to fix this integer overflow bug.

------------------

From: Cong Wang <[email protected]>

[ Upstream commit 0c3057a5a04d07120b3d0ec9c79568fceb9c921e ]

The function qdisc_tree_reduce_backlog() uses TC_H_ROOT as a termination condition when traversing up the qdisc tree to update parent backlog counters. However, if a class is created with classid TC_H_ROOT, the traversal terminates prematurely at this class instead of reaching the actual root qdisc, causing parent statistics to be incorrectly maintained. In case of DRR, this could lead to a crash as reported by Mingi Cho.

Prevent the creation of any Qdisc class with classid TC_H_ROOT (0xFFFFFFFF) across all qdisc types, as suggested by Jamal.

PATCH 16/279 netfilter: nft_exthdr: fix offset with ipv4_find_option()

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Alexey Kashavkin <[email protected]>

[ Upstream commit 6edd78af9506bb182518da7f6feebd75655d9a0e ]

There is an incorrect calculation in the offset variable which causes the nft_skb_copy_to_reg() function to always return -EFAULT. Adding the start variable is redundant. In the __ip_options_compile() function the correct offset is specified when finding the function. There is no need to add the size of the iphdr structure to the offset.

PATCH 17/279 gre: Fix IPv6 link-local address generation.

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Guillaume Nault <[email protected]>

[ Upstream commit 183185a18ff96751db52a46ccf93fff3a1f42815 ]

Use addrconf_addr_gen() to generate IPv6 link-local addresses on GRE devices in most cases and fall back to using add_v4_addrs() only in case the GRE configuration is incompatible with addrconf_addr_gen().

GRE used to use addrconf_addr_gen() until commit e5dd729460ca ("ip/ip6_gre: use the same logic as SIT interfaces when computing v6LL address") restricted this use to gretap and ip6gretap devices, and created add_v4_addrs() (borrowed from SIT) for non-Ethernet GRE ones.

The original problem came when commit 9af28511be10 ("addrconf: refuse isatap eui64 for INADDR_ANY") made __ipv6_isatap_ifid() fail when its addr parameter was 0. The commit says that this would create an invalid address, however, I couldn't find any RFC saying that the generated interface identifier would be wrong. Anyway, since gre over IPv4 devices pass their local tunnel address to __ipv6_isatap_ifid(), that commit broke their IPv6 link-local address generation when the local address was unspecified.

Then commit e5dd729460ca ("ip/ip6_gre: use the same logic as SIT interfaces when computing v6LL address") tried to fix that case by defining add_v4_addrs() and calling it to generate the IPv6 link-local address instead of using addrconf_addr_gen() (apart for gretap and ip6gretap devices, which would still use the regular addrconf_addr_gen(), since they have a MAC address).

That broke several use cases because add_v4_addrs() isn't properly integrated into the rest of IPv6 Neighbor Discovery code. Several of these shortcomings have been fixed over time, but add_v4_addrs() remains broken on several aspects. In particular, it doesn't send any Router Sollicitations, so the SLAAC process doesn't start until the interface receives a Router Advertisement. Also, add_v4_addrs() mostly ignores the address generation mode of the interface (/proc/sys/net/ipv6/conf/*/addr_gen_mode), thus breaking the IN6_ADDR_GEN_MODE_RANDOM and IN6_ADDR_GEN_MODE_STABLE_PRIVACY cases.

Fix the situation by using add_v4_addrs() only in the specific scenario where the normal method would fail. That is, for interfaces that have all of the following characteristics:

* run over IPv4,
* transport IP packets directly, not Ethernet (that is, not gretap interfaces),
* tunnel endpoint is INADDR_ANY (that is, 0),
* device address generation mode is EUI64.

In all other cases, revert back to the regular addrconf_addr_gen().

Also, remove the special case for ip6gre interfaces in add_v4_addrs(), since ip6gre devices now always use addrconf_addr_gen() instead.

PATCH 19/279 slab: Introduce kmalloc_size_roundup()

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Kees Cook <[email protected]>

[ Upstream commit 05a940656e1eb2026d9ee31019d5b47e9545124d ]

In the effort to help the compiler reason about buffer sizes, the __alloc_size attribute was added to allocators. This improves the scope of the compiler's ability to apply CONFIG_UBSAN_BOUNDS and (in the near future) CONFIG_FORTIFY_SOURCE. For most allocations, this works well, as the vast majority of callers are not expecting to use more memory than what they asked for.

There is, however, one common exception to this: anticipatory resizing of kmalloc allocations. These cases all use ksize() to determine the actual bucket size of a given allocation (e.g. 128 when 126 was asked for). This comes in two styles in the kernel:

1) An allocation has been determined to be too small, and needs to be resized. Instead of the caller choosing its own next best size, it wants to minimize the number of calls to krealloc(), so it just uses ksize() plus some additional bytes, forcing the realloc into the next bucket size, from which it can learn how large it is now. For example:

	data = krealloc(data, ksize(data) + 1, gfp);
	data_len = ksize(data);

2) The minimum size of an allocation is calculated, but since it may grow in the future, just use all the space available in the chosen bucket immediately, to avoid needing to reallocate later. A good example of this is skbuff's allocators:

	data = kmalloc_reserve(size, gfp_mask, node, &pfmemalloc);
	...
	/* kmalloc(size) might give us more room than requested.
	 * Put skb_shared_info exactly at the end of allocated zone,
	 * to allow max possible filling before reallocation.
	 */
	osize = ksize(data);
        size = SKB_WITH_OVERHEAD(osize);

In both cases, the "how much was actually allocated?" question is answered _after_ the allocation, where the compiler hinting is not in an easy place to make the association any more. This mismatch between the compiler's view of the buffer length and the code's intention about how much it is going to actually use has already caused problems[1]. It is possible to fix this by reordering the use of the "actual size" information.

We can serve the needs of users of ksize() and still have accurate buffer length hinting for the compiler by doing the bucket size calculation _before_ the allocation. Code can instead ask "how large an allocation would I get for a given size?".

Introduce kmalloc_size_roundup(), to serve this function so we can start replacing the "anticipatory resizing" uses of ksize().

PATCH 21/279 net: openvswitch: remove misbehaving actions length check

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Ilya Maximets <[email protected]>

[ Upstream commit a1e64addf3ff9257b45b78bc7d743781c3f41340 ]

The actions length check is unreliable and produces different results depending on the initial length of the provided netlink attribute and the composition of the actual actions inside of it. For example, a user can add 4088 empty clone() actions without triggering -EMSGSIZE, on attempt to add 4089 such actions the operation will fail with the -EMSGSIZE verdict. However, if another 16 KB of other actions will be *appended* to the previous 4089 clone() actions, the check passes and the flow is successfully installed into the openvswitch datapath.

The reason for a such a weird behavior is the way memory is allocated. When ovs_flow_cmd_new() is invoked, it calls ovs_nla_copy_actions(), that in turn calls nla_alloc_flow_actions() with either the actual length of the user-provided actions or the MAX_ACTIONS_BUFSIZE. The function adds the size of the sw_flow_actions structure and then the actually allocated memory is rounded up to the closest power of two.

So, if the user-provided actions are larger than MAX_ACTIONS_BUFSIZE, then MAX_ACTIONS_BUFSIZE + sizeof(*sfa) rounded up is 32K + 24 -> 64K. Later, while copying individual actions, we look at ksize(), which is 64K, so this way the MAX_ACTIONS_BUFSIZE check is not actually triggered and the user can easily allocate almost 64 KB of actions.

However, when the initial size is less than MAX_ACTIONS_BUFSIZE, but the actions contain ones that require size increase while copying (such as clone() or sample()), then the limit check will be performed during the reserve_sfa_size() and the user will not be allowed to create actions that yield more than 32 KB internally.

This is one part of the problem. The other part is that it's not actually possible for the userspace application to know beforehand if the particular set of actions will be rejected or not.

Certain actions require more space in the internal representation, e.g. an empty clone() takes 4 bytes in the action list passed in by the user, but it takes 12 bytes in the internal representation due to an extra nested attribute, and some actions require less space in the internal representations, e.g. set(tunnel(..)) normally takes 64+ bytes in the action list provided by the user, but only needs to store a single pointer in the internal implementation, since all the data is stored in the tunnel_info structure instead.

And the action size limit is applied to the internal representation, not to the action list passed by the user. So, it's not possible for the userpsace application to predict if the certain combination of actions will be rejected or not, because it is not possible for it to calculate how much space these actions will take in the internal representation without knowing kernel internals.

All that is causing random failures in ovs-vswitchd in userspace and inability to handle certain traffic patterns as a result. For example, it is reported that adding a bit more than a 1100 VMs in an OpenStack setup breaks the network due to OVS not being able to handle ARP traffic anymore in some cases (it tries to install a proper datapath flow, but the kernel rejects it with -EMSGSIZE, even though the action list isn't actually that large.)

Kernel behavior must be consistent and predictable in order for the userspace application to use it in a reasonable way. ovs-vswitchd has a mechanism to re-direct parts of the traffic and partially handle it in userspace if the required action list is oversized, but that doesn't work properly if we can't actually tell if the action list is oversized or not.

Solution for this is to check the size of the user-provided actions instead of the internal representation. This commit just removes the check from the internal part because there is already an implicit size check imposed by the netlink protocol. The attribute can't be larger than 64 KB. Realistically, we could reduce the limit to 32 KB, but we'll be risking to break some existing setups that rely on the fact that it's possible to create nearly 64 KB action lists today.

Vast majority of flows in real setups are below 100-ish bytes. So removal of the limit will not change real memory consumption on the system. The absolutely worst case scenario is if someone adds a flow with 64 KB of empty clone() actions. That will yield a 192 KB in the internal representation consuming 256 KB block of memory. However, that list of actions is not meaningful and also a no-op. Real world very large action lists (that can occur for a rare cases of BUM traffic handling) are unlikely to contain a large number of clones and will likely have a lot of tunnel attributes making the internal representation comparable in size to the original action list. So, it should be fine to just remove the limit.

Commit in the 'Fixes' tag is the first one that introduced the difference between internal representation and the user-provided action lists, but there were many more afterwards that lead to the situation we have today.

PATCH 22/279 net/mlx5: Bridge, fix the crash caused by LAG state check

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Jianbo Liu <[email protected]>

[ Upstream commit 4b8eeed4fb105770ce6dc84a2c6ef953c7b71cbb ]

When removing LAG device from bridge, NETDEV_CHANGEUPPER event is triggered. Driver finds the lower devices (PFs) to flush all the offloaded entries. And mlx5_lag_is_shared_fdb is checked, it returns false if one of PF is unloaded. In such case, mlx5_esw_bridge_lag_rep_get() and its caller return NULL, instead of the alive PF, and the flush is skipped.

Besides, the bridge fdb entry's lastuse is updated in mlx5 bridge event handler. But this SWITCHDEV_FDB_ADD_TO_BRIDGE event can be ignored in this case because the upper interface for bond is deleted, and the entry will never be aged because lastuse is never updated.

To make things worse, as the entry is alive, mlx5 bridge workqueue keeps sending that event, which is then handled by kernel bridge notifier. It causes the following crash when accessing the passed bond netdev which is already destroyed.

To fix this issue, remove such checks. LAG state is already checked in commit 15f8f168952f ("net/mlx5: Bridge, verify LAG state when adding bond to bridge"), driver still need to skip offload if LAG becomes invalid state after initialization.

PATCH 23/279 net/mlx5e: Prevent bridge link show failure for non-eswitch-allowed devices

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Carolina Jubran <[email protected]>

[ Upstream commit e92df790d07a8eea873efcb84776e7b71f81c7d5 ]

mlx5_eswitch_get_vepa returns -EPERM if the device lacks eswitch_manager capability, blocking mlx5e_bridge_getlink from retrieving VEPA mode. Since mlx5e_bridge_getlink implements ndo_bridge_getlink, returning -EPERM causes bridge link show to fail instead of skipping devices without this capability.

To avoid this, return -EOPNOTSUPP from mlx5e_bridge_getlink when mlx5_eswitch_get_vepa fails, ensuring the command continues processing other devices while ignoring those without the necessary capability.

PATCH 24/279 nvme-fc: go straight to connecting state when initializing

------------------

From: Daniel Wagner <[email protected]>

[ Upstream commit d3d380eded7ee5fc2fc53b3b0e72365ded025c4a ]

The initial controller initialization mimiks the reconnect loop behavior by switching from NEW to RESETTING and then to CONNECTING.

The transition from NEW to CONNECTING is a valid transition, so there is no point entering the RESETTING state. TCP and RDMA also transition directly to CONNECTING state.

PATCH 26/279 powercap: call put_device() on an error path in powercap_register_control_type()

powercap_register_control_type() calls device_register(), but does not release the refcount of the device when it fails.

Call put_device() before returning an error to balance the refcount.

Since the kfree(control_type) will be done by powercap_release(), remove the lines in powercap_register_control_type() before returning the error.

This bug was found by an experimental verifier that I am developing.

When performing an iSCSI boot using IPv6, iscsistart still reads the /sys/firmware/ibft/ethernetX/subnet-mask entry. Since the IPv6 prefix length is 64, this causes the shift exponent to become negative, triggering a UBSAN warning. As the concept of a subnet mask does not apply to IPv6, the value is set to ~0 to suppress the warning message.

Filesystems can write to disk from page reclaim with __GFP_FS set. Marc found a case where scsi_realloc_sdev_budget_map() ends up in page reclaim with GFP_KERNEL, where it could try to take filesystem locks again, leading to a deadlock.

WARNING: possible circular locking dependency detected

A null dereference or oops exception will eventually occur when qla1280.c driver is compiled with DEBUG_QLA1280 enabled and ql_debug_level > 2. I think its clear from the code that the intention here is sg_dma_len(s) not length of sg_next(s) when printing the debug info.

PATCH 30/279 ACPI: resource: IRQ override for Eluktronics MECH-17

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Gannon Kolding <[email protected]>

[ Upstream commit 607ab6f85f4194b644ea95ac5fe660ef575db3b4 ]

The Eluktronics MECH-17 (GM7RG7N) needs IRQ overriding for the keyboard to work.

Adding a DMI_MATCH entry for this laptop model makes the internal keyboard function normally.

PATCH 31/279 alpha/elf: Fix misc/setarch test of util-linux by removing 32bit support

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Eric W. Biederman <[email protected]>

[ Upstream commit b029628be267cba3c7684ec684749fe3e4372398 ]

Richard Henderson <[email protected]> writes[1]:

Quoted 11 lines

There was a Spec benchmark (I forget which) which was memory bound and ran twice as fast with 32-bit pointers.

I copied the idea from DEC to the ELF abi, but never did all the other work to allow the toolchain to take advantage.

Amusingly, a later Spec changed the benchmark data sets to not fit into a 32-bit address space, specifically because of this.

I expect one could delete the ELF bit and personality and no one would notice. Not even the 10 remaining Alpha users.

In [2] it was pointed out that parts of setarch weren't working properly on alpha because it has it's own SET_PERSONALITY implementation. In the discussion that followed Richard Henderson pointed out that the 32bit pointer support for alpha was never completed.

Fix this by removing alpha's 32bit pointer support.

As a bit of paranoia refuse to execute any alpha binaries that have the EF_ALPHA_32BIT flag set. Just in case someone somewhere has binaries that try to use alpha's 32bit pointer support.

PATCH 33/279 HID: intel-ish-hid: fix the length of MNG_SYNC_FW_CLOCK in doorbell

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Zhang Lixu <[email protected]>

[ Upstream commit 4b54ae69197b9f416baa0fceadff7e89075f8454 ]

The timestamps in the Firmware log and HID sensor samples are incorrect. They show 1970-01-01 because the current IPC driver only uses the first 8 bytes of bootup time when synchronizing time with the firmware. The firmware converts the bootup time to UTC time, which results in the display of 1970-01-01.

In write_ipc_from_queue(), when sending the MNG_SYNC_FW_CLOCK message, the clock is updated according to the definition of ipc_time_update_msg. However, in _ish_sync_fw_clock(), the message length is specified as the size of uint64_t when building the doorbell. As a result, the firmware only receives the first 8 bytes of struct ipc_time_update_msg. This patch corrects the length in the doorbell to ensure the entire ipc_time_update_msg is sent, fixing the timestamp issue.

PATCH 34/279 HID: ignore non-functional sensor in HP 5MP Camera

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

From: Chia-Lin Kao (AceLan) <[email protected]>

[ Upstream commit 363236d709e75610b628c2a4337ccbe42e454b6d ]

The HP 5MP Camera (USB ID 0408:5473) reports a HID sensor interface that is not actually implemented. Attempting to access this non-functional sensor via iio_info causes system hangs as runtime PM tries to wake up an unresponsive sensor.

[453] hid-sensor-hub 0003:0408:5473.0003: Report latency attributes: ffffffff:ffffffff
[453] hid-sensor-hub 0003:0408:5473.0003: common attributes: 5:1, 2:1, 3:1 ffffffff:ffffffff

Add this device to the HID ignore list since the sensor interface is non-functional by design and should not be exposed to userspace.

PATCH 36/279 s390/cio: Fix CHPID "configure" attribute caching

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Peter Oberparleiter <[email protected]>

[ Upstream commit 32ae4a2992529e2c7934e422035fad1d9b0f1fb5 ]

In some environments, the SCLP firmware interface used to query a CHPID's configured state is not supported. On these environments, rapidly reading the corresponding sysfs attribute produces inconsistent results:

  $ cat /sys/devices/css0/chp0.00/configure
  cat: /sys/devices/css0/chp0.00/configure: Operation not supported
  $ cat /sys/devices/css0/chp0.00/configure
  3

This occurs for example when Linux is run as a KVM guest. The inconsistency is a result of CIO using cached results for generating the value of the "configure" attribute while failing to handle the situation where no data was returned by SCLP.

Fix this by not updating the cache-expiration timestamp when SCLP returns no data. With the fix applied, the system response is consistent:

  $ cat /sys/devices/css0/chp0.00/configure
  cat: /sys/devices/css0/chp0.00/configure: Operation not supported
  $ cat /sys/devices/css0/chp0.00/configure

PATCH 38/279 ASoC: rsnd: dont indicate warning on rsnd_kctrl_accept_runtime()

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Kuninori Morimoto <[email protected]>

[ Upstream commit c3fc002b206c6c83d1e3702b979733002ba6fb2c ]

rsnd_kctrl_accept_runtime() (1) is used for runtime convert rate (= Synchronous SRC Mode). Now, rsnd driver has 2 kctrls for it

(A): "SRC Out Rate Switch"
(B): "SRC Out Rate" // it calls (1)

(A): can be called anytime
(B): can be called only runtime, and will indicate warning if it was used
at non-runtime.

To use runtime convert rate (= Synchronous SRC Mode), user might uses command in below order.

(X): > amixer set "SRC Out Rate" on
> aplay xxx.wav &
(Y): > amixer set "SRC Out Rate" 48010 // convert rate to 48010Hz

(Y): calls B
(X): calls both A and B.

In this case, when user calls (X), it calls both (A) and (B), but it is not yet start running. So, (B) will indicate warning.

This warning was added by commit b5c088689847 ("ASoC: rsnd: add warning message to rsnd_kctrl_accept_runtime()"), but the message sounds like the operation was not correct. Let's update warning message.

The message is very SRC specific, implement it in src.c

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Vitaly Rodionov <[email protected]>

[ Upstream commit 679074942c2502a95842a80471d8fb718165ac77 ]

Using fsleep instead of msleep resolves some customer complaints regarding the precision of up/down DAPM event timing. fsleep() automatically selects the appropriate sleep function, making the delay time more predictable.

PATCH 41/279 net: wwan: mhi_wwan_mbim: Silence sequence number glitch errors

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Stephan Gerhold <[email protected]>

[ Upstream commit 0d1fac6d26aff5df21bb4ec980d9b7a11c410b96 ]

When using the Qualcomm X55 modem on the ThinkPad X13s, the kernel log is constantly being filled with errors related to a "sequence number glitch", e.g.:

	[ 1903.284538] sequence number glitch prev=16 curr=0
	[ 1913.812205] sequence number glitch prev=50 curr=0
	[ 1923.698219] sequence number glitch prev=142 curr=0
	[ 2029.248276] sequence number glitch prev=1555 curr=0
	[ 2046.333059] sequence number glitch prev=70 curr=0
	[ 2076.520067] sequence number glitch prev=272 curr=0
	[ 2158.704202] sequence number glitch prev=2655 curr=0
	[ 2218.530776] sequence number glitch prev=2349 curr=0
	[ 2225.579092] sequence number glitch prev=6 curr=0

Internet connectivity is working fine, so this error seems harmless. It looks like modem does not preserve the sequence number when entering low power state; the amount of errors depends on how actively the modem is being used.

A similar issue has also been seen on USB-based MBIM modems [1]. However, in cdc_ncm.c the "sequence number glitch" message is a debug message instead of an error. Apply the same to the mhi_wwan_mbim.c driver to silence these errors when using the modem.

PATCH 43/279 sctp: Fix undefined behavior in left shift operation

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Yu-Chun Lin <[email protected]>

[ Upstream commit 606572eb22c1786a3957d24307f5760bb058ca19 ]

According to the C11 standard (ISO/IEC 9899:2011, 6.5.7):
"If E1 has a signed type and E1 x 2^E2 is not representable in the result type, the behavior is undefined."

Shifting 1 << 31 causes signed integer overflow, which leads to undefined behavior.

Fix this by explicitly using '1U << 31' to ensure the shift operates on an unsigned type, avoiding undefined behavior.

From: Daniel Wagner <[email protected]>

[ Upstream commit d2fe192348f93fe3a0cb1e33e4aba58e646397f4 ]

The fabric transports and also the PCI transport are not entering the LIVE state from NEW or RESETTING. This makes the state machine more restrictive and allows to catch not supported state transitions, e.g. directly switching from RESETTING to LIVE.

PATCH 48/279 fuse: dont truncate cached, mutated symlink

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Miklos Szeredi <[email protected]>

[ Upstream commit b4c173dfbb6c78568578ff18f9e8822d7bd0e31b ]

Fuse allows the value of a symlink to change and this property is exploited by some filesystems (e.g. CVMFS).

It has been observed, that sometimes after changing the symlink contents, the value is truncated to the old size.

This is caused by fuse_getattr() racing with fuse_reverse_inval_inode(). fuse_reverse_inval_inode() updates the fuse_inode's attr_version, which results in fuse_change_attributes() exiting before updating the cached attributes

This is okay, as the cached attributes remain invalid and the next call to fuse_change_attributes() will likely update the inode with the correct values.

The reason this causes problems is that cached symlinks will be returned through page_get_link(), which truncates the symlink to inode->i_size. This is correct for filesystems that don't mutate symlinks, but in this case it causes bad behavior.

The solution is to just remove this truncation. This can cause a regression in a filesystem that relies on supplying a symlink larger than the file size, but this is unlikely. If that happens we'd need to make this behavior conditional.

PATCH 49/279 x86/irq: Define trace events conditionally

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Arnd Bergmann <[email protected]>

[ Upstream commit 9de7695925d5d2d2085681ba935857246eb2817d ]

When both of X86_LOCAL_APIC and X86_THERMAL_VECTOR are disabled, the irq tracing produces a W=1 build warning for the tracing definitions:

In file included from include/trace/trace_events.h:27,

                 from include/trace/define_trace.h:113,

include/trace/stages/init.h:2:23: error: 'str__irq_vectors__trace_system_name' defined but not used [-Werror=unused-const-variable=]

Make the tracepoints conditional on the same symbosl that guard their usage.

PATCH 50/279 mptcp: safety check before fallback

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Matthieu Baerts (NGI0) <[email protected]>

[ Upstream commit db75a16813aabae3b78c06b1b99f5e314c1f55d3 ]

Recently, some fallback have been initiated, while the connection was not supposed to fallback.

Add a safety check with a warning to detect when an wrong attempt to fallback is being done. This should help detecting any future issues quicker.

PATCH 53/279 USB: serial: ftdi_sio: add support for Altera USB Blaster 3

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Boon Khai Ng <[email protected]>

commit 18e0885bd2ca738407036434418a26a58394a60e upstream.

The Altera USB Blaster 3, available as both a cable and an on-board solution, is primarily used for programming and debugging FPGAs.

It interfaces with host software such as Quartus Programmer, System Console, SignalTap, and Nios Debugger. The device utilizes either an FT2232 or FT4232 chip.

Enabling the support for various configurations of the on-board USB Blaster 3 by including the appropriate VID/PID pairs, allowing it to function as a serial device via ftdi_sio.

Note that this check-in does not include support for the cable solution, as it does not support UART functionality. The supported configurations are determined by the hardware design and include:

1) PID 0x6022, FT2232, 1 JTAG port (Port A) + Port B as UART
2) PID 0x6025, FT4232, 1 JTAG port (Port A) + Port C as UART
3) PID 0x6026, FT4232, 1 JTAG port (Port A) + Port C, D as UART
4) PID 0x6029, FT4232, 1 JTAG port (Port B) + Port C as UART
5) PID 0x602a, FT4232, 1 JTAG port (Port B) + Port C, D as UART
6) PID 0x602c, FT4232, 1 JTAG port (Port A) + Port B as UART
7) PID 0x602d, FT4232, 1 JTAG port (Port A) + Port B, C as UART
8) PID 0x602e, FT4232, 1 JTAG port (Port A) + Port B, C, D as UART

These configurations allow for flexibility in how the USB Blaster 3 is used, depending on the specific needs of the hardware design.

PATCH 56/279 USB: serial: option: match on interface class for Telit FN990B

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Johan Hovold <[email protected]>

commit 9a665fe3d967fe46edb4fd2497c7a5cc2dac2f55 upstream.

The device id entries for Telit FN990B ended up matching only on the interface protocol. While this works, the protocol is qualified by the interface class (and subclass) which should have been included.

Switch to matching using USB_DEVICE_AND_INTERFACE_INFO() while keeping the entries sorted also by protocol for consistency.

PATCH 57/279 x86/microcode/AMD: Fix out-of-bounds on systems with CPU-less NUMA nodes

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Florent Revest <[email protected]>

commit e3e89178a9f4a80092578af3ff3c8478f9187d59 upstream.

Currently, load_microcode_amd() iterates over all NUMA nodes, retrieves their CPU masks and unconditionally accesses per-CPU data for the first CPU of each mask.

According to Documentation/admin-guide/mm/numaperf.rst:

"Some memory may share the same node as a CPU, and others are provided as memory only nodes."

Therefore, some node CPU masks may be empty and wouldn't have a "first CPU".

On a machine with far memory (and therefore CPU-less NUMA nodes):
- cpumask_of_node(nid) is 0
- cpumask_first(0) is CONFIG_NR_CPUS
- cpu_data(CONFIG_NR_CPUS) accesses the cpu_info per-CPU array at an index that is 1 out of bounds

This does not have any security implications since flashing microcode is a privileged operation but I believe this has reliability implications by potentially corrupting memory while flashing a microcode update.

When booting with CONFIG_UBSAN_BOUNDS=y on an AMD machine that flashes a microcode update. I get the following splat:

  UBSAN: array-index-out-of-bounds in arch/x86/kernel/cpu/microcode/amd.c:X:Y
  index 512 is out of range for type 'unsigned long[512]'
  [...]
  Call Trace:
   dump_stack
   __ubsan_handle_out_of_bounds
   load_microcode_amd
   request_microcode_amd
   reload_store
   kernfs_fop_write_iter
   vfs_write
   ksys_write
   do_syscall_64
   entry_SYSCALL_64_after_hwframe

Change the loop to go over only NUMA nodes which have CPUs before determining whether the first CPU on the respective node needs microcode update.

PATCH 58/279 drm/atomic: Filter out redundant DPMS calls

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Ville Syrjälä <[email protected]>

commit de93ddf88088f7624b589d0ff3af9effb87e8f3b upstream.

Video players (eg. mpv) do periodic XResetScreenSaver() calls to keep the screen on while the video playing. The modesetting ddx plumbs these straight through into the kernel as DPMS setproperty ioctls, without any filtering whatsoever. When implemented via atomic these end up as empty commits on the crtc (which will nonetheless take one full frame), which leads to a dropped frame every time XResetScreenSaver() is called.

Let's just filter out redundant DPMS property changes in the kernel to avoid this issue.

v2: Explain the resulting commits a bit better (Sima)
Document the behaviour in uapi docs (Sima)

PATCH 59/279 drm/amd/display: Restore correct backlight brightness after a GPU reset

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Mario Limonciello <[email protected]>

commit 5760388d9681ac743038b846b9082b9023969551 upstream.

[Why]
GPU reset will attempt to restore cached state, but brightness doesn't get restored. It will come back at 100% brightness, but userspace thinks it's the previous value.

[How]
When running resume sequence if GPU is in reset restore brightness to previous value.

PATCH 60/279 drm/amd/display: Assign normalized_pix_clk when color depth = 14

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Alex Hung <[email protected]>

commit 79e31396fdd7037c503e6add15af7cb00633ea92 upstream.

[WHY & HOW]
A warning message "WARNING: CPU: 4 PID: 459 at ... /dc_resource.c:3397 calculate_phy_pix_clks+0xef/0x100 [amdgpu]" occurs because the display_color_depth == COLOR_DEPTH_141414 is not handled. This is observed in Radeon RX 6600 XT.

It is fixed by assigning pix_clk * (14 * 3) / 24 - same as the rests.

Also fixes the indentation in get_norm_pix_clk.

PATCH 63/279 lib/buildid: Handle memfd_secret() files in build_id_parse()

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Andrii Nakryiko <[email protected]>

commit 5ac9b4e935dfc6af41eee2ddc21deb5c36507a9f upstream.

Quoted 1 line

From memfd_secret(2) manpage:

The memory areas backing the file created with memfd_secret(2) are visible only to the processes that have access to the file descriptor. The memory region is removed from the kernel page tables and only the page tables of the processes holding the file descriptor map the corresponding physical memory. (Thus, the pages in the region can't be accessed by the kernel itself, so that, for example, pointers to the region can't be passed to system calls.)

We need to handle this special case gracefully in build ID fetching code. Return -EFAULT whenever secretmem file is passed to build_id_parse() family of APIs. Original report and repro can be found in [0].

PATCH 64/279 tcp: fix races in tcp_abort()

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Eric Dumazet <[email protected]>

commit 5ce4645c23cf5f048eb8e9ce49e514bababdee85 upstream.

tcp_abort() has the same issue than the one fixed in the prior patch in tcp_write_err().

In order to get consistent results from tcp_poll(), we must call sk_error_report() after tcp_done().

We can use tcp_done_with_error() to centralize this logic.

PATCH 65/279 ASoC: ops: Consistently treat platform_max as control value

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Charles Keepax <[email protected]>

[ Upstream commit 0eba2a7e858907a746ba69cd002eb9eb4dbd7bf3 ]

This reverts commit 9bdd10d57a88 ("ASoC: ops: Shift tested values in snd_soc_put_volsw() by +min"), and makes some additional related updates.

There are two ways the platform_max could be interpreted; the maximum register value, or the maximum value the control can be set to. The patch moved from treating the value as a control value to a register one. When the patch was applied it was technically correct as snd_soc_limit_volume() also used the register interpretation. However, even then most of the other usages treated platform_max as a control value, and snd_soc_limit_volume() has since been updated to also do so in commit fb9ad24485087 ("ASoC: ops: add correct range check for limiting volume"). That patch however, missed updating snd_soc_put_volsw() back to the control interpretation, and fixing snd_soc_info_volsw_range(). The control interpretation makes more sense as limiting is typically done from the machine driver, so it is appropriate to use the customer facing representation rather than the internal codec representation. Update all the code to consistently use this interpretation of platform_max.

Finally, also add some comments to the soc_mixer_control struct to hopefully avoid further patches switching between the two approaches.

Fixes fb9ad24485087 ("ASoC: ops: add correct range check for limiting volume")

PATCH 66/279 drm/gma500: Add NULL check for pci_gfx_root in mid_get_vbt_data()

From: Ivan Abramov <[email protected]>

[ Upstream commit 374c9faac5a763a05bc3f68ad9f73dab3c6aec90 ]

Null pointer dereference issue could occur when pipe_ctx->plane_state is null. The fix adds a check to ensure 'pipe_ctx->plane_state' is not null before accessing. This prevents a null pointer dereference.

PATCH 80/279 xfrm_output: Force software GSO only in tunnel mode

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Cosmin Ratiu <[email protected]>

[ Upstream commit 0aae2867aa6067f73d066bc98385e23c8454a1d7 ]

The cited commit fixed a software GSO bug with VXLAN + IPSec in tunnel mode. Unfortunately, it is slightly broader than necessary, as it also severely affects performance for Geneve + IPSec transport mode over a device capable of both HW GSO and IPSec crypto offload. In this case, xfrm_output unnecessarily triggers software GSO instead of letting the HW do it. In simple iperf3 tests over Geneve + IPSec transport mode over a back-2-back pair of NICs with MTU 1500, the performance was observed to be up to 6x worse when doing software GSO compared to leaving it to the hardware.

This commit makes xfrm_output only trigger software GSO in crypto offload cases for already encapsulated packets in tunnel mode, as not doing so would then cause the inner tunnel skb->inner_networking_header to be overwritten and break software GSO for that packet later if the device turns out to not be capable of HW GSO.

Taking a closer look at the conditions for the original bug, to better understand the reasons for this change:
- vxlan_build_skb -> iptunnel_handle_offloads sets inner_protocol and inner network header.
- then, udp_tunnel_xmit_skb -> ip_tunnel_xmit adds outer transport and network headers.
- later in the xmit path, xfrm_output -> xfrm_outer_mode_output -> xfrm4_prepare_output -> xfrm4_tunnel_encap_add overwrites the inner network header with the one set in ip_tunnel_xmit before adding the second outer header.
- __dev_queue_xmit -> validate_xmit_skb checks whether GSO segmentation needs to happen based on dev features. In the original bug, the hw couldn't segment the packets, so skb_gso_segment was invoked.
- deep in the .gso_segment callback machinery, __skb_udp_tunnel_segment tries to use the wrong inner network header, expecting the one set in iptunnel_handle_offloads but getting the one set by xfrm instead.
- a bit later, ipv6_gso_segment accesses the wrong memory based on that wrong inner network header.

With the new change, the original bug (or similar ones) cannot happen again, as xfrm will now trigger software GSO before applying a tunnel. This concern doesn't exist in packet offload mode, when the HW adds encapsulation headers. For the non-offloaded packets (crypto in SW), software GSO is still done unconditionally in the else branch.

PATCH 86/279 RDMA/hns: Fix soft lockup during bt pages loop

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Junxian Huang <[email protected]>

[ Upstream commit 25655580136de59ec89f09089dd28008ea440fc9 ]

Driver runs a for-loop when allocating bt pages and mapping them with buffer pages. When a large buffer (e.g. MR over 100GB) is being allocated, it may require a considerable loop count. This will lead to soft lockup:

        watchdog: BUG: soft lockup - CPU#27 stuck for 22s!
        ...
        Call trace:
         hem_list_alloc_mid_bt+0x124/0x394 [hns_roce_hw_v2]

         ib_uverbs_reg_mr+0x120/0x2bc

Add a cond_resched() to fix soft lockup during these loops. In order not to affect the allocation performance of normal-size buffer, set the loop count of a 100GB MR as the threshold to call cond_resched().

Fixes 38389eaa4db1 ("RDMA/hns: Add mtr support for mixed multihop addressing")

PATCH 87/279 RDMA/hns: Fix unmatched condition in error path of alloc_user_qp_db()

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Junxian Huang <[email protected]>

[ Upstream commit b9f59a24ba35a7d955a9f8e148dd9f85b7b40a01 ]

Currently the condition of unmapping sdb in error path is not exactly the same as the condition of mapping in alloc_user_qp_db(). This may cause a problem of unmapping an unmapped db in some case, such as when the QP is XRC TGT. Unified the two conditions.

PATCH 91/279 ipv6: Fix memleak of nhc_pcpu_rth_output in fib_check_nh_v6_gw().

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Kuniyuki Iwashima <[email protected]>

[ Upstream commit 9740890ee20e01f99ff1dde84c63dcf089fabb98 ]

fib_check_nh_v6_gw() expects that fib6_nh_init() cleans up everything when it fails.

Commit 7dd73168e273 ("ipv6: Always allocate pcpu memory in a fib6_nh") moved fib_nh_common_init() before alloc_percpu_gfp() within fib6_nh_init() but forgot to add cleanup for fib6_nh->nh_common.nhc_pcpu_rth_output in case it fails to allocate fib6_nh->rt6i_pcpu, resulting in memleak.

Let's call fib_nh_common_release() and clear nhc_pcpu_rth_output in the error path.

Note that we can remove the fib6_nh_release() call in nh_create_ipv6() later in net-next.git.

From: Kuniyuki Iwashima <[email protected]>

[ Upstream commit 9a81fc3480bf5dbe2bf80e278c440770f6ba2692 ]

While creating a new IPv6, we could get a weird -ENOMEM when RTA_NH_ID is set and either of the conditions below is true:

1) CONFIG_IPV6_SUBTREES is enabled and rtm_src_len is specified
2) nexthop_get() fails

e.g.)

  # strace ip -6 route add fe80::dead:beef:dead:beef nhid 1 from ::
  recvmsg(3, {msg_iov=[{iov_base=[...[
    {error=-ENOMEM, msg=[... [...]]},
    [{nla_len=49, nla_type=NLMSGERR_ATTR_MSG}, "Nexthops can not be used with so"...]
  ]], iov_len=32768}], msg_iovlen=1, msg_controllen=0, msg_flags=0}, 0) = 148

Let's set err explicitly after ip_fib_metrics_init() in ip6_route_info_create().

PATCH 96/279 i2c: omap: fix IRQ storms

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Andreas Kemnade <[email protected]>

commit 285df995f90e3d61d97f327d34b9659d92313314 upstream.

On the GTA04A5 writing a reset command to the gyroscope causes IRQ storms because NACK IRQs are enabled and therefore triggered but not acked.

Sending a reset command to the gyroscope by
i2cset 1 0x69 0x14 0xb6
with an additional debug print in the ISR (not the thread) itself causes

[ 363.353515] i2c i2c-1: ioctl, cmd=0x720, arg=0xbe801b00
[ 363.359039] omap_i2c 48072000.i2c: addr: 0x0069, len: 2, flags: 0x0, stop: 1
[ 363.366180] omap_i2c 48072000.i2c: IRQ LL (ISR = 0x1110)
[ 363.371673] omap_i2c 48072000.i2c: IRQ (ISR = 0x0010)
[ 363.376892] omap_i2c 48072000.i2c: IRQ LL (ISR = 0x0102)
[ 363.382263] omap_i2c 48072000.i2c: IRQ LL (ISR = 0x0102)
[ 363.387664] omap_i2c 48072000.i2c: IRQ LL (ISR = 0x0102)

repeating till infinity
[...]
(0x2 = NACK, 0x100 = Bus free, which is not enabled) Apparently no other IRQ bit gets set, so this stalls.

Do not ignore enabled interrupts and make sure they are acked. If the NACK IRQ is not needed, it should simply not enabled, but according to the above log, caring about it is necessary unless the Bus free IRQ is enabled and handled. The assumption that is will always come with a ARDY IRQ, which was the idea behind ignoring it, proves wrong.
It is true for simple reads from an unused address.

To still avoid the i2cdetect trouble which is the reason for commit c770657bd261 ("i2c: omap: Fix standard mode false ACK readings"), avoid doing much about NACK in omap_i2c_xfer_data() which is used by both IRQ mode and polling mode, so also the false detection fix is extended to polling usage and IRQ storms are avoided.

By changing this, the hardirq handler is not needed anymore to filter stuff.

The mentioned gyro reset now just causes a -ETIMEDOUT instead of hanging the system.

PATCH 97/279 drm/v3d: Dont run jobs that have errors flagged in its fence

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Maíra Canal <[email protected]>

commit 80cbee810e4e13cdbd3ae9654e9ecddf17f3e828 upstream.

The V3D driver still relies on drm_sched_increase_karma() and drm_sched_resubmit_jobs() for resubmissions when a timeout occurs. The function drm_sched_increase_karma() marks the job as guilty, while drm_sched_resubmit_jobs() sets an error (-ECANCELED) in the DMA fence of that guilty job.

Because of this, we must check whether the job’s DMA fence has been flagged with an error before executing the job. Otherwise, the same guilty job may be resubmitted indefinitely, causing repeated GPU resets.

This patch adds a check for an error on the job's fence to prevent running a guilty job that was previously flagged when the GPU timed out.

Note that the CPU and CACHE_CLEAN queues do not require this check, as their jobs are executed synchronously once the DRM scheduler starts them.

Fixes d223f98f0209 ("drm/v3d: Add support for compute shader dispatch.")
Fixes 1584f16ca96e ("drm/v3d: Add support for submitting jobs to the TFU.")

PATCH 98/279 regulator: check that dummy regulator has been probed before using it

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Christian Eggers <[email protected]>

commit 2c7a50bec4958f1d1c84d19cde518d0e96a676fd upstream.

Due to asynchronous driver probing there is a chance that the dummy regulator hasn't already been probed when first accessing it.

PATCH 100/279 proc: fix UAF in proc_get_inode()

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Ye Bin <[email protected]>

commit 654b33ada4ab5e926cd9c570196fefa7bec7c1df upstream.

Fix race between rmmod and /proc/XXX's inode instantiation.

The bug is that pde->proc_ops don't belong to /proc, it belongs to a module, therefore dereferencing it after /proc entry has been registered is a bug unless use_pde/unuse_pde() pair has been used.

use_pde/unuse_pde can be avoided (2 atomic ops!) because pde->proc_ops never changes so information necessary for inode instantiation can be saved _before_ proc_register() in PDE itself and used later, avoiding pde->proc_ops->... dereference.

PATCH 102/279 batman-adv: Ignore own maximum aggregation size during RX

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Sven Eckelmann <[email protected]>

commit 548b0c5de7619ef53bbde5590700693f2f6d2a56 upstream.

An OGMv1 and OGMv2 packet receive processing were not only limited by the number of bytes in the received packet but also by the nodes maximum aggregation packet size limit. But this limit is relevant for TX and not for RX. It must not be enforced by batadv_(i)v_ogm_aggr_packet to avoid loss of information in case of a different limit for sender and receiver.

This has a minor side effect for B.A.T.M.A.N. IV because the batadv_iv_ogm_aggr_packet is also used for the preprocessing for the TX. But since the aggregation code itself will not allow more than BATADV_MAX_AGGREGATION_BYTES bytes, this check was never triggering (in this context) prior of removing it.

Fixes c6c8fea29769 ("net: Add batman-adv meshing protocol")
Fixes 9323158ef9f4 ("batman-adv: OGMv2 - implement originators logic")

PATCH 103/279 soc: qcom: pdr: Fix the potential deadlock

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Saranya R <[email protected]>

commit 2eeb03ad9f42dfece63051be2400af487ddb96d2 upstream.

When some client process A call pdr_add_lookup() to add the look up for the service and does schedule locator work, later a process B got a new server packet indicating locator is up and call pdr_locator_new_server() which eventually sets pdr->locator_init_complete to true which process A sees and takes list lock and queries domain list but it will timeout due to deadlock as the response will queued to the same qmi->wq and it is ordered workqueue and process B is not able to complete new server request work due to deadlock on list lock.

Fix it by removing the unnecessary list iteration as the list iteration is already being done inside locator work, so avoid it here and just call schedule_work() here.

Process A Process B

process_scheduled_works()
pdr_add_lookup() qmi_data_ready_work()
process_scheduled_works() pdr_locator_new_server()

                                         pdr->locator_init_complete=true;
   pdr_locator_work()
    mutex_lock(&pdr->list_lock);

     pdr_locate_service()                  mutex_lock(&pdr->list_lock);

      pdr_get_domain_list()
       pr_err("PDR: %s get domain list
               txn wait failed: %d\n",
               req->service_name,
               ret);

Timeout error log due to deadlock:

"
PDR: tms/servreg get domain list txn wait failed: -110
PDR: service lookup for msm/adsp/sensor_pd:tms/servreg failed: -110
"

Thanks to Bjorn and Johan for letting me know that this commit also fixes an audio regression when using the in-kernel pd-mapper as that makes it easier to hit this race. [1]

PATCH 104/279 drm/radeon: fix uninitialized size issue in radeon_vce_cs_parse()

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Nikita Zhandarovich <[email protected]>

commit dd8689b52a24807c2d5ce0a17cb26dc87f75235c upstream.

On the off chance that command stream passed from userspace via ioctl() call to radeon_vce_cs_parse() is weirdly crafted and first command to execute is to encode (case 0x03000001), the function in question will attempt to call radeon_vce_cs_reloc() with size argument that has not been properly initialized. Specifically, 'size' will point to 'tmp' variable before the latter had a chance to be assigned any value.

Play it safe and init 'tmp' with 0, thus ensuring that radeon_vce_cs_reloc() will catch an early error in cases like these.

Found by Linux Verification Center (linuxtesting.org) with static analysis tool SVACE.

Fixes 2fc5703abda2 ("drm/radeon: check VCE relocation buffer range v3")

PATCH 106/279 mptcp: Fix data stream corruption in the address announcement

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Arthur Mongodin <[email protected]>

commit 2c1f97a52cb827a5f2768e67a9dddffae1ed47ab upstream.

Because of the size restriction in the TCP options space, the MPTCP ADD_ADDR option is exclusive and cannot be sent with other MPTCP ones. For this reason, in the linked mptcp_out_options structure, group of fields linked to different options are part of the same union.

There is a case where the mptcp_pm_add_addr_signal() function can modify opts->addr, but not ended up sending an ADD_ADDR. Later on, back in mptcp_established_options, other options will be sent, but with unexpected data written in other fields due to the union, e.g. in opts->ext_copy. This could lead to a data stream corruption in the next packet.

Using an intermediate variable, prevents from corrupting previously established DSS option. The assignment of the ADD_ADDR option parameters is now done once we are sure this ADD_ADDR option can be set in the packet, e.g. after having dropped other suboptions.

Fixes 1bff1e43a30e ("mptcp: optimize out option generation")

[ Matt: the commit message has been updated: long lines splits and some
clarifications. ]

PATCH 107/279 arm64: dts: rockchip: fix u2phy1_host status for NanoPi R4S

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Justin Klaassen <[email protected]>

commit 38f4aa34a5f737ea8588dac320d884cc2e762c03 upstream.

The u2phy1_host should always have the same status as usb_host1_ehci and usb_host1_ohci, otherwise the EHCI and OHCI drivers may be initialized for a disabled usb port.

Per the NanoPi R4S schematic, the phy-supply for u2phy1_host is set to the vdd_5v regulator.

PATCH 108/279 Bluetooth: hci_event: Align BR/EDR JUST_WORKS paring with LE

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

From: Luiz Augusto von Dentz <[email protected]>

commit b25e11f978b63cb7857890edb3a698599cddb10e upstream.

This aligned BR/EDR JUST_WORKS method with LE which since 92516cd97fd4 ("Bluetooth: Always request for user confirmation for Just Works") always request user confirmation with confirm_hint set since the likes of bluetoothd have dedicated policy around JUST_WORKS method (e.g. main.conf:JustWorksRepairing).

CVE: CVE-2024-8805

PATCH 109/279 bpf, sockmap: Fix race between element replace and close()

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Michal Luczaj <[email protected]>

commit ed1fc5d76b81a4d681211333c026202cad4d5649 upstream.

Element replace (with a socket different from the one stored) may race with socket's close() link popping & unlinking. __sock_map_delete() unconditionally unrefs the (wrong) element:

// set map[0] = s0
map_update_elem(map, 0, s0)

// drop fd of s0
close(s0)
sock_map_close()

    lock_sock(sk)               (s0!)
    sock_map_remove_links(sk)
      link = sk_psock_link_pop()
      sock_map_unlink(sk, link)
        sock_map_delete_from_link
                                        // replace map[0] with s1
                                        map_update_elem(map, 0, s1)

              sock_map_unref(sk, psk)        // unref s1; sks[idx] will dangle
                psock = sk_psock(sk)

                    sk_psock_drop(sk, psock)
            spin_unlock(&stab->lock)
    release_sock(sk)

Then close(map) enqueues bpf_map_free_deferred, which finally calls sock_map_free(). This results in some refcount_t warnings along with a KASAN splat [1].

Fix __sock_map_delete(), do not allow sock_map_unref() on elements that may have been replaced.

PATCH 110/279 ALSA: usb-audio: Add quirk for Plantronics headsets to fix control names

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Terry Junge <[email protected]>

commit 486f6205c233da1baa309bde5f634eb1f8319a33 upstream.

Many Poly/Plantronics headset families name the feature, input, and/or output units in a such a way to produce control names that are not recognized by user space. As such, the volume and mute events do not get routed to the headset's audio controls.

As an example from a product family:

The microphone mute control is named
Headset Microphone Capture Switch
and the headset volume control is named
Headset Earphone Playback Volume

The quirk fixes these to become
Headset Capture Switch
Headset Playback Volume

PATCH 111/279 HID: hid-plantronics: Add mic mute mapping and generalize quirks

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Terry Junge <[email protected]>

commit 9821709af892be9fbf4ee9a50b2f3e0604295ce0 upstream.

Add mapping for headset mute key events.

Remove PLT_QUIRK_DOUBLE_VOLUME_KEYS quirk and made it generic. The quirk logic did not keep track of the actual previous key so any key event occurring in less than or equal to 5ms was ignored.

Remove PLT_QUIRK_FOLLOWED_OPPOSITE_VOLUME_KEYS quirk.
It had the same logic issue as the double key quirk and was actually masking the as designed behavior of most of the headsets. It's occurrence should be minimized with the ALSA control naming quirk that is part of the patch set.

PATCH 112/279 atm: Fix NULL pointer dereference

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Minjoong Kim <[email protected]>

commit bf2986fcf82a449441f9ee4335df19be19e83970 upstream.

When MPOA_cache_impos_rcvd() receives the msg, it can trigger Null Pointer Dereference Vulnerability if both entry and holding_time are NULL. Because there is only for the situation where entry is NULL and holding_time exists, it can be passed when both entry and holding_time are NULL. If these are NULL, the entry will be passd to eg_cache_put() as parameter and it is referenced by entry->use code in it.

PATCH 113/279 ARM: 9350/1: fault: Implement copy_from_kernel_nofault_allowed()

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Kees Cook <[email protected]>

commit 169f9102f9198b04afffa6164372a4ba4070f412 upstream.

Under PAN emulation when dumping backtraces from things like the LKDTM EXEC_USERSPACE test[1], a double fault (which would hang a CPU) would happen because of dump_instr() attempting to read a userspace address. Make sure copy_from_kernel_nofault() does not attempt this any more.

PATCH 115/279 ARM: Remove address checking for MMUless devices

In reply to Greg Kroah-Hartman

Commit 169f9102f9198b ("ARM: 9350/1: fault: Implement copy_from_kernel_nofault_allowed()") added the function to check address before use. However, for devices without MMU, addr > TASK_SIZE will always fail. This patch move this function after the #ifdef CONFIG_MMU statement.

PATCH 116/279 netfilter: socket: Lookup orig tuple for IPv6 SNAT

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Maxim Mikityanskiy <[email protected]>

commit 932b32ffd7604fb00b5c57e239a3cc4d901ccf6e upstream.

nf_sk_lookup_slow_v4 does the conntrack lookup for IPv4 packets to restore the original 5-tuple in case of SNAT, to be able to find the right socket (if any). Then socket_match() can correctly check whether the socket was transparent.

However, the IPv6 counterpart (nf_sk_lookup_slow_v6) lacks this conntrack lookup, making xt_socket fail to match on the socket when the packet was SNATed. Add the same logic to nf_sk_lookup_slow_v6.

IPv6 SNAT is used in Kubernetes clusters for pod-to-world packets, as pods' addresses are in the fd00::/8 ULA subnet and need to be replaced with the node's external address. Cilium leverages Envoy to enforce L7 policies, and Envoy uses transparent sockets. Cilium inserts an iptables prerouting rule that matches on -m socket --transparent and redirects the packets to localhost, but it fails to match SNATed IPv6 packets due to that missing conntrack lookup.

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

From: Dhruv Deshpande <[email protected]>

commit 35ef1c79d2e09e9e5a66e28a66fe0df4368b0f3d upstream.

The mute LED on this HP laptop uses ALC236 and requires a quirk to function. This patch enables the existing quirk for the device.

Tested on my laptop and the LED behaviour works as intended.

PATCH 118/279 counter: stm32-lptimer-cnt: fix error handling when enabling

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Fabrice Gasnier <[email protected]>

commit 8744dcd4fc7800de2eb9369410470bb2930d4c14 upstream.

In case the stm32_lptim_set_enable_state() fails to update CMP and ARR, a timeout error is raised, by regmap_read_poll_timeout. It may happen, when the lptimer runs on a slow clock, and the clock is gated only few times during the polling.

Badly, when this happen, STM32_LPTIM_ENABLE in CR register has been set. So the 'enable' state in sysfs wrongly lies on the counter being correctly enabled, due to CR is read as one in stm32_lptim_is_enabled().

To fix both issues:
- enable the clock before writing CMP, ARR and polling ISR bits. It will avoid the possible timeout error.
- clear the ENABLE bit in CR and disable the clock in the error path.

Fixes d8958824cf07 ("iio: counter: Add support for STM32 LPTimer")

PATCH 119/279 counter: microchip-tcb-capture: Fix undefined counter channel state on probe

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

commit c0c9c73434666dc99ee156b25e7e722150bee001 upstream.

Hardware initialize of the timer counter channel does not occur on probe thus leaving the Count in an undefined state until the first function_write() callback is executed. Fix this by performing the proper hardware initialization during probe.

PATCH 124/279 net: usb: usbnet: restore usb%d name exception for local mac addresses

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Dominique Martinet <[email protected]>

commit 2ea396448f26d0d7d66224cb56500a6789c7ed07 upstream.

commit 8a7d12d674ac ("net: usb: usbnet: fix name regression") assumed that local addresses always came from the kernel, but some devices hand out local mac addresses so we ended up with point-to-point devices with a mac set by the driver, renaming to eth%d when they used to be named usb%d.

Userspace should not rely on device name, but for the sake of stability restore the local mac address check portion of the naming exception:
point to point devices which either have no mac set by the driver or have a local mac handed out by the driver will keep the usb%d name.

(some USB LTE modems are known to hand out a stable mac from the locally administered range; that mac appears to be random (different for mulitple devices) and can be reset with device-specific commands, so while such devices would benefit from getting a OUI reserved, we have to deal with these and might as well preserve the existing behavior to avoid breaking fragile openwrt configurations and such on upgrade.)

PATCH 127/279 media: i2c: et8ek8: Dont strip remove function when driver is builtin

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Uwe Kleine-König <[email protected]>

commit 545b215736c5c4b354e182d99c578a472ac9bfce upstream.

Using __exit for the remove function results in the remove callback being discarded with CONFIG_VIDEO_ET8EK8=y. When such a device gets unbound (e.g. using sysfs or hotplug), the driver is just removed without the cleanup being performed. This results in resource leaks. Fix it by compiling in the remove callback unconditionally.

This also fixes a W=1 modpost warning:

	WARNING: modpost: drivers/media/i2c/et8ek8/et8ek8: section mismatch in reference: et8ek8_i2c_driver+0x10 (section: .data) -> et8ek8_remove (section: .exit.text)

PATCH 128/279 watch_queue: fix pipe accounting mismatch

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Eric Sandeen <[email protected]>

[ Upstream commit f13abc1e8e1a3b7455511c4e122750127f6bc9b0 ]

Currently, watch_queue_set_size() modifies the pipe buffers charged to user->pipe_bufs without updating the pipe->nr_accounted on the pipe itself, due to the if (!pipe_has_watch_queue()) test in pipe_resize_ring(). This means that when the pipe is ultimately freed, we decrement user->pipe_bufs by something other than what than we had charged to it, potentially leading to an underflow. This in turn can cause subsequent too_many_pipe_buffers_soft() tests to fail with -EPERM.

To remedy this, explicitly account for the pipe usage in watch_queue_set_size() to match the number set via account_pipe_buffers()

(It's unclear why watch_queue_set_size() does not update nr_accounted; it may be due to intentional overprovisioning in watch_queue_set_size()?)

PATCH 130/279 cpufreq: scpi: compare kHz instead of Hz

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: zuoqian <[email protected]>

[ Upstream commit 4742da9774a416908ef8e3916164192c15c0e2d1 ]

The CPU rate from clk_get_rate() may not be divisible by 1000 (e.g., 133333333). But the rate calculated from frequency(kHz) is always divisible by 1000 (e.g., 133333000).
Comparing the rate causes a warning during CPU scaling:
"cpufreq: __target_index: Failed to change cpu frequency: -5". When we choose to compare kHz here, the issue does not occur.

PATCH 131/279 cpufreq: governor: Fix negative idle_time handling in dbs_update()

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Jie Zhan <[email protected]>

[ Upstream commit 3698dd6b139dc37b35a9ad83d9330c1f99666c02 ]

We observed an issue that the CPU frequency can't raise up with a 100% CPU load when NOHZ is off and the 'conservative' governor is selected.

'idle_time' can be negative if it's obtained from get_cpu_idle_time_jiffy() when NOHZ is off. This was found and explained in commit 9485e4ca0b48 ("cpufreq: governor: Fix handling of special cases in dbs_update()").

However, commit 7592019634f8 ("cpufreq: governors: Fix long idle detection logic in load calculation") introduced a comparison between 'idle_time' and 'samling_rate' to detect a long idle interval. While 'idle_time' is converted to int before comparison, it's actually promoted to unsigned again when compared with an unsigned 'sampling_rate'. Hence, this leads to wrong idle interval detection when it's in fact 100% busy and sets policy_dbs->idle_periods to a very large value. 'conservative' adjusts the frequency to minimum because of the large 'idle_periods', such that the frequency can't raise up. 'Ondemand' doesn't use policy_dbs->idle_periods so it fortunately avoids the issue.

Correct negative 'idle_time' to 0 before any use of it in dbs_update().

PATCH 132/279 x86/fpu: Avoid copying dynamic FP state from init_task in arch_dup_task_struct()

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Benjamin Berg <[email protected]>

[ Upstream commit 5d3b81d4d8520efe888536b6906dc10fd1a228a8 ]

The init_task instance of struct task_struct is statically allocated and may not contain the full FP state for userspace. As such, limit the copy to the valid area of both init_task and 'dst' and ensure all memory is initialized.

Note that the FP state is only needed for userspace, and as such it is entirely reasonable for init_task to not contain parts of it.

PATCH 135/279 selinux: Chain up tool resolving errors in install_policy.sh

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Tim Schumacher <[email protected]>

[ Upstream commit 6ae0042f4d3f331e841495eb0a3d51598e593ec2 ]

Subshell evaluations are not exempt from errexit, so if a command is not available, which will fail and exit the script as a whole. This causes the helpful error messages to not be printed if they are tacked on using a $? comparison.

Resolve the issue by using chains of logical operators, which are not subject to the effects of errexit.

PATCH 139/279 thermal: int340x: Add NULL check for adev

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

From: Chenyuan Yang <[email protected]>

[ Upstream commit 2542a3f70e563a9e70e7ded314286535a3321bdb ]

Not all devices have an ACPI companion fwnode, so adev might be NULL. This is similar to the commit cd2fd6eab480
("platform/x86: int3472: Check for adev == NULL").

Add a check for adev not being set and return -ENODEV in that case to avoid a possible NULL pointer deref in int3402_thermal_probe().

PATCH 140/279 PM: sleep: Fix handling devices with direct_complete set on errors

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Rafael J. Wysocki <[email protected]>

[ Upstream commit 03f1444016b71feffa1dfb8a51f15ba592f94b13 ]

When dpm_suspend() fails, some devices with power.direct_complete set may not have been handled by device_suspend() yet, so runtime PM has not been disabled for them yet even though power.direct_complete is set.

Since device_resume() expects that runtime PM has been disabled for all devices with power.direct_complete set, it will attempt to reenable runtime PM for the devices that have not been processed by device_suspend() which does not make sense. Had those devices had runtime PM disabled before device_suspend() had run, device_resume() would have inadvertently enable runtime PM for them, but this is not expected to happen because it would require ->prepare() callbacks to return positive values for devices with runtime PM disabled, which would be invalid.

In practice, this issue is most likely benign because pm_runtime_enable() will not allow the "disable depth" counter to underflow, but it causes a warning message to be printed for each affected device.

To allow device_resume() to distinguish the "direct complete" devices that have been processed by device_suspend() from those which have not been handled by it, make device_suspend() set power.is_suspended for "direct complete" devices.

Next, move the power.is_suspended check in device_resume() before the power.direct_complete check in it to make it skip the "direct complete" devices that have not been handled by device_suspend().

This change is based on a preliminary patch from Saravana Kannan.

PATCH 141/279 lockdep: Dont disable interrupts on RT in disable_irq_nosync_lockdep.*()

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Sebastian Andrzej Siewior <[email protected]>

[ Upstream commit 87886b32d669abc11c7be95ef44099215e4f5788 ]

disable_irq_nosync_lockdep() disables interrupts with lockdep enabled to avoid false positive reports by lockdep that a certain lock has not been acquired with disabled interrupts. The user of this macros expects that a lock can be acquried without disabling interrupts because the IRQ line triggering the interrupt is disabled.

This triggers a warning on PREEMPT_RT because after disable_irq_nosync_lockdep.*() the following spinlock_t now is acquired with disabled interrupts.

On PREEMPT_RT there is no difference between spin_lock() and spin_lock_irq() so avoiding disabling interrupts in this case works for the two remaining callers as of today.

Don't disable interrupts on PREEMPT_RT in disable_irq_nosync_lockdep.*().

PATCH 145/279 ALSA: hda/realtek: Always honor no_shutup_pins

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Takashi Iwai <[email protected]>

[ Upstream commit 5a0c72c1da3cbc0cd4940a95d1be2830104c6edf ]

The workaround for Dell machines to skip the pin-shutup for mic pins introduced alc_headset_mic_no_shutup() that is replaced from the generic snd_hda_shutup_pins() for certain codecs. The problem is that the call is done unconditionally even if spec->no_shutup_pins is set. This seems causing problems on other platforms like Lenovo.

This patch corrects the behavior and the driver honors always spec->no_shutup_pins flag and skips alc_headset_mic_no_shutup() if it's set.

For 'ti,j7200-cpb-audio' compatible, there is support for only one PLL for 48k. For 11025, 22050, 44100 and 88200 sampling rates, due to absence of J721E_CLK_PARENT_44100, we get EINVAL while running any audio application.

PATCH 147/279 drm/bridge: ti-sn65dsi86: Fix multiple instances

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Geert Uytterhoeven <[email protected]>

[ Upstream commit 574f5ee2c85a00a579549d50e9fc9c6c072ee4c4 ]

Each bridge instance creates up to four auxiliary devices with different names. However, their IDs are always zero, causing duplicate filename errors when a system has multiple bridges:

sysfs: cannot create duplicate filename '/bus/auxiliary/devices/ti_sn65dsi86.gpio.0'

Fix this by using a unique instance ID per bridge instance. The instance ID is derived from the I2C adapter number and the bridge's I2C address, to support multiple instances on the same bus.

PATCH 148/279 drm/dp_mst: Fix drm RAD print

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Wayne Lin <[email protected]>

[ Upstream commit 6bbce873a9c97cb12f5455c497be279ac58e707f ]

[Why]
The RAD of sideband message printed today is incorrect.
For RAD stored within MST branch
- If MST branch LCT is 1, it's RAD array is untouched and remained as 0.
- If MST branch LCT is larger than 1, use nibble to store the up facing port number in cascaded sequence as illustrated below:

u8 RAD[0] = (LCT_2_UFP << 4) | LCT_3_UFP

     RAD[1] = (LCT_4_UFP << 4) | LCT_5_UFP
     ...

In drm_dp_mst_rad_to_str(), it wrongly to use BIT_MASK(4) to fetch the port number of one nibble.

[How]
Adjust the code by:
- RAD array items are valuable only for LCT >= 1.
- Use 0xF as the mask to replace BIT_MASK(4)

V2:
- Document how RAD is constructed (Imre)

V3:
- Adjust the comment for rad[] so kdoc formats it properly (Lyude)

PATCH 150/279 drm/vkms: Fix use after free and double free on init error

In reply to Greg Kroah-Hartman

From: José Expósito <[email protected]>

[ Upstream commit ed15511a773df86205bda66c37193569575ae828 ]

If the driver initialization fails, the vkms_exit() function might access an uninitialized or freed default_config pointer and it might double free it.

Fix both possible errors by initializing default_config only when the driver initialization succeeded.

PATCH 151/279 drm/mediatek: mtk_hdmi: Unregister audio platform device on failure

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: AngeloGioacchino Del Regno <[email protected]>

[ Upstream commit 0be123cafc06eed0fd1227166a66e786434b0c50 ]

The probe function of this driver may fail after registering the audio platform device: in that case, the state is not getting cleaned up, leaving this device registered.

Adding up to the mix, should the probe function of this driver return a probe deferral for N times, we're registering up to N audio platform devices and, again, never freeing them up.

To fix this, add a pointer to the audio platform device in the mtk_hdmi structure, and add a devm action to unregister it upon driver removal or probe failure.

PATCH 153/279 PCI/ASPM: Fix link state exit during switch upstream function removal

In reply to Greg Kroah-Hartman

5.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Daniel Stodden <[email protected]>

[ Upstream commit cbf937dcadfd571a434f8074d057b32cd14fbea5 ]

Before 456d8aa37d0f ("PCI/ASPM: Disable ASPM on MFD function removal to avoid use-after-free"), we would free the ASPM link only after the last function on the bus pertaining to the given link was removed.

That was too late. If function 0 is removed before sibling function, link->downstream would point to free'd memory after.

After above change, we freed the ASPM parent link state upon any function removal on the bus pertaining to a given link.

That is too early. If the link is to a PCIe switch with MFD on the upstream port, then removing functions other than 0 first would free a link which still remains parent_link to the remaining downstream ports.

The resulting GPFs are especially frequent during hot-unplug, because pciehp removes devices on the link bus in reverse order.

On that switch, function 0 is the virtual P2P bridge to the internal bus. Free exactly when function 0 is removed -- before the parent link is obsolete, but after all subordinate links are gone.

Fixes 456d8aa37d0f ("PCI/ASPM: Disable ASPM on MFD function removal to avoid use-after-free")
