PATCH 1/91 ata: ahci: fix enum constants for gcc-13

From: Arnd Bergmann <[email protected]>

commit f07788079f515ca4a681c5f595bdad19cfbd7b1d upstream.

gcc-13 slightly changes the type of constant expressions that are defined in an enum, which triggers a compile time sanity check in libata:

linux/drivers/ata/libahci.c: In function 'ahci_led_store':
linux/include/linux/compiler_types.h:357:45: error: call to '__compiletime_assert_302' declared with attribute error: BUILD_BUG_ON failed: sizeof(_s) > sizeof(long) 357 | _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__)

The new behavior is that sizeof() returns the same value for the constant as it does for the enum type, which is generally more sensible and consistent.

The problem in libata is that it contains a single enum definition for lots of unrelated constants, some of which are large positive (unsigned) integers like 0xffffffff, while others like (1<<31) are interpreted as negative integers, and this forces the enum type to become 64 bit wide even though most constants would still fit into a signed 32-bit 'int'.

Fix this by changing the entire enum definition to use BIT(x) in place of (1<<x), which results in all values being seen as 'unsigned' and fitting into an unsigned 32-bit type.

PATCH 2/91 gcc-plugins: Reorganize gimple includes for GCC 13

In reply to Greg Kroah-Hartman

From: Kees Cook <[email protected]>

mainline commit: e6a71160cc145e18ab45195abf89884112e02dfb

The gimple-iterator.h header must be included before gimple-fold.h starting with GCC 13. Reorganize gimple headers to work for all GCC versions.

PATCH 3/91 remove the sx8 block driver

In reply to Greg Kroah-Hartman

From: Christoph Hellwig <[email protected]>

commit d13bc4d84a8e91060d3797fc95c1a0202bfd1499 upstream.

This driver is for fairly obscure hardware, and has only seen random drive-by changes after the maintainer stopped working on it in 2005 (about a year and a half after it was introduced). It has some "interesting" block layer interactions, so let's just drop it unless anyone complains.

PATCH 4/91 sfc (gcc13): synchronize ef100_enqueue_skb()s return type

In reply to Greg Kroah-Hartman

From: Jiri Slaby (SUSE) <[email protected]>

commit 3319dbb3e755398f254c3daa04b9030197137efe upstream.

ef100_enqueue_skb() generates a valid warning with gcc-13:
drivers/net/ethernet/sfc/ef100_tx.c:370:5: error: conflicting types for 'ef100_enqueue_skb' due to enum/integer mismatch; have 'int(struct efx_tx_queue *, struct sk_buff *)' drivers/net/ethernet/sfc/ef100_tx.h:25:13: note: previous declaration of 'ef100_enqueue_skb' with type 'netdev_tx_t(struct efx_tx_queue *, struct sk_buff *)'

I.e. the type of the ef100_enqueue_skb()'s return value in the declaration is int, while the definition spells enum netdev_tx_t. Synchronize them to the latter.

PATCH 5/91 i40e: Remove string printing for i40e_status

In reply to Greg Kroah-Hartman

From: Jan Sokolowski <[email protected]>

commit 5d968af27a166e055bdd5f832f095d809eadb992 upstream.

Remove the i40e_stat_str() function which prints the string representation of the i40e_status error code. With upcoming changes moving away from i40e_status, there will be no need for this function

PATCH 6/91 i40e: use int for i40e_status

In reply to Greg Kroah-Hartman

From: Jan Sokolowski <[email protected]>

commit 5180ff1364bc26c031b54a68a80aa90ce0028b70 upstream.

To prepare for removal of i40e_status, change the variables from i40e_status to int. This eases the transition when values are changed to return standard int error codes over enum i40e_status.

As such changes often also change variable orders, a cleanup is also applied here to make variables conform to RCT and some lines are also reformatted where applicable.

PATCH 7/91 i40e: fix build warning in ice_fltr_add_mac_to_list()

In reply to Greg Kroah-Hartman

Not upstream as this was fixed in a much larger change in commit 5e24d5984c80 ("ice: Use int for ice_status")

The function ice_fltr_add_mac_to_list() has the wrong prototype match from the .h file to the .c declaration, so fix it up, otherwise gcc-13 complains (rightfully) that the type is incorrect.

PATCH 10/91 blk-iocost: avoid 64-bit division in ioc_timer_fn

In reply to Greg Kroah-Hartman

From: Arnd Bergmann <[email protected]>

commit 5f2779dfa7b8cc7dfd4a1b6586d86e0d193266f3 upstream.

The behavior of 'enum' types has changed in gcc-13, so now the UNBUSY_THR_PCT constant is interpreted as a 64-bit number because it is defined as part of the same enum definition as some other constants that do not fit within a 32-bit integer. This in turn leads to some inefficient code on 32-bit architectures as well as a link error:

arm-linux-gnueabi/bin/arm-linux-gnueabi-ld: block/blk-iocost.o: in function `ioc_timer_fn':
blk-iocost.c:(.text+0x68e8): undefined reference to `__aeabi_uldivmod'
arm-linux-gnueabi-ld: blk-iocost.c:(.text+0x6908): undefined reference to `__aeabi_uldivmod'

Split the enum definition to keep the 64-bit timing constants in a separate enum type from those constants that can clearly fit within a smaller type.

PATCH 11/91 platform/surface: aggregator: Allow completion work-items to be executed in parallel

In reply to Greg Kroah-Hartman

From: Maximilian Luz <[email protected]>

[ Upstream commit 539e0a7f9105d19c00629c3f4da00330488e8c60 ]

Currently, event completion work-items are restricted to be run strictly in non-parallel fashion by the respective workqueue. However, this has lead to some problems:

In some instances, the event notifier function called inside this completion workqueue takes a non-negligible amount of time to execute. One such example is the battery event handling code (surface_battery.c), which can result in a full battery information refresh, involving further synchronous communication with the EC inside the event handler. This is made worse if the communication fails spuriously, generally incurring a multi-second timeout.

Since the event completions are run strictly non-parallel, this blocks other events from being propagated to the respective subsystems. This becomes especially noticeable for keyboard and touchpad input, which also funnel their events through this system. Here, users have reported occasional multi-second "freezes".

Note, however, that the event handling system was never intended to run purely sequentially. Instead, we have one work struct per EC/SAM subsystem, processing the event queue for that subsystem. These work structs were intended to run in parallel, allowing sequential processing of work items for each subsystem but parallel processing of work items across subsystems.

The only restriction to this is the way the workqueue is created. Therefore, replace create_workqueue() with alloc_workqueue() and do not restrict the maximum number of parallel work items to be executed on that queue, resolving any cross-subsystem blockage.

PATCH 12/91 spi: qup: Request DMA before enabling clocks

In reply to Greg Kroah-Hartman

From: Stephan Gerhold <[email protected]>

[ Upstream commit 0c331fd1dccfba657129380ee084b95c1cedfbef ]

It is usually better to request all necessary resources (clocks, regulators, ...) before starting to make use of them. That way they do not change state in case one of the resources is not available yet and probe deferral (-EPROBE_DEFER) is necessary. This is particularly important for DMA channels and IOMMUs which are not enforced by fw_devlink yet (unless you use fw_devlink.strict=1).

spi-qup does this in the wrong order, the clocks are enabled and disabled again when the DMA channels are not available yet.

This causes issues in some cases: On most SoCs one of the SPI QUP clocks is shared with the UART controller. When using earlycon UART is actively used during boot but might not have probed yet, usually for the same reason (waiting for the DMA controller). In this case, the brief enable/disable cycle ends up gating the clock and further UART console output will halt the system completely.

Avoid this by requesting the DMA channels before changing the clock state.

PATCH 13/91 afs: Fix setting of mtime when creating a file/dir/symlink

In reply to Greg Kroah-Hartman

From: David Howells <[email protected]>

[ Upstream commit a27648c742104a833a01c54becc24429898d85bf ]

kafs incorrectly passes a zero mtime (ie. 1st Jan 1970) to the server when creating a file, dir or symlink because the mtime recorded in the afs_operation struct gets passed to the server by the marshalling routines, but the afs_mkdir(), afs_create() and afs_symlink() functions don't set it.

This gets masked if a file or directory is subsequently modified.

Fix this by filling in op->mtime before calling the create op.

Fixes e49c7b2f6de7 ("afs: Build an abstraction around an "operation" concept")

PATCH 15/91 neighbour: fix unaligned access to pneigh_entry

In reply to Greg Kroah-Hartman

From: Qingfang DENG <[email protected]>

[ Upstream commit ed779fe4c9b5a20b4ab4fd6f3e19807445bb78c7 ]

After the blamed commit, the member key is longer 4-byte aligned. On platforms that do not support unaligned access, e.g., MIPS32R2 with unaligned_action set to 1, this will trigger a crash when accessing an IPv6 pneigh_entry, as the key is cast to an in6_addr pointer.

Change the type of the key to u32 to make it aligned.

PATCH 16/91 net: dsa: lan9303: allow vid != 0 in port_fdb_{add|del} methods

PATCH 17/91 bpf: Fix UAF in task local storage

In reply to Greg Kroah-Hartman

From: KP Singh <[email protected]>

[ Upstream commit b0fd1852bcc21accca6260ef245356d5c141ff66 ]

When task local storage was generalized for tracing programs, the bpf_task_local_storage callback was moved from a BPF LSM hook callback for security_task_free LSM hook to it's own callback. But a failure case in bad_fork_cleanup_security was missed which, when triggered, led to a dangling task owner pointer and a subsequent use-after-free. Move the bpf_task_storage_free to the very end of free_task to handle all failure cases.

This issue was noticed when a BPF LSM program was attached to the task_alloc hook on a kernel with KASAN enabled. The program used bpf_task_storage_get to copy the task local storage from the current task to the new task being created.

PATCH 18/91 net/ipv6: fix bool/int mismatch for skip_notify_on_dev_down

From: Eric Dumazet <[email protected]>

[ Upstream commit edf2e1d2019b2730d6076dbe4c040d37d7c10bbe ]

skip_notify_on_dev_down ctl table expects this field to be an int (4 bytes), not a bool (1 byte).

Because proc_dou8vec_minmax() was added in 5.13, this patch converts skip_notify_on_dev_down to an int.

Following patch then converts the field to u8 and use proc_dou8vec_minmax().

When an alernate RNIC is available in system, SMC will try to add a new link based on the RNIC for resilience. All the RMBs in use will be mapped to the new link. Then the RMBs' MRs corresponding to the new link will be filled into LLC messages. For SMCRv1, they are ADD LINK CONT messages.

However smc_llc_add_link_cont() may mistakenly access to unused RMBs which haven't been mapped to the new link and have no valid MRs, thus causing a crash. So this patch fixes it.

PATCH 20/91 net: enetc: correct the statistics of rx bytes

In reply to Greg Kroah-Hartman

From: Wei Fang <[email protected]>

[ Upstream commit 7190d0ff0e17690a9b1279d84a06473600ba2060 ]

The rx_bytes of struct net_device_stats should count the length of ethernet frames excluding the FCS. However, there are two problems with the rx_bytes statistics of the current enetc driver. one is that the length of VLAN header is not counted if the VLAN extraction feature is enabled. The other is that the length of L2 header is not counted, because eth_type_trans() is invoked before updating rx_bytes which will subtract the length of L2 header from skb->len. BTW, the rx_bytes statistics of XDP path also have similar problem, I will fix it in another patch.

PATCH 22/91 drm/i915: Explain the magic numbers for AUX SYNC/precharge length

In reply to Greg Kroah-Hartman

From: Ville Syrjälä <[email protected]>

[ Upstream commit 26bfc3f36f2104c174dfc72415547d5c28ef3f1c ]

Replace the hardcoded final numbers in the AUX SYNC/precharge setup, and derive those from numbers from the (e)DP specs.

The new functions can serve as the single point of truth for the number of SYNC pulses we use.

PATCH 23/91 drm/i915: Use 18 fast wake AUX sync len

In reply to Greg Kroah-Hartman

From: Jouni Högander <[email protected]>

[ Upstream commit 2d6f2f79e06571d41eb1223abebe9097511c9544 ]

HW default for wake sync pulses is 18. 10 precharge and 8 preamble. There is no reason to change this especially as it is causing problems with certain eDP panels.

v3: Change "Fixes:" commit
v2: Remove "fast wake" repeat from subject

PATCH 24/91 Bluetooth: Fix l2cap_disconnect_req deadlock

In reply to Greg Kroah-Hartman

From: Ying Hsu <[email protected]>

[ Upstream commit 02c5ea5246a44d6ffde0fddebfc1d56188052976 ]

L2CAP assumes that the locks conn->chan_lock and chan->lock are acquired in the order conn->chan_lock, chan->lock to avoid potential deadlock.
For example, l2sock_shutdown acquires these locks in the order:
mutex_lock(&conn->chan_lock)
l2cap_chan_lock(chan)

However, l2cap_disconnect_req acquires chan->lock in l2cap_get_chan_by_scid first and then acquires conn->chan_lock before calling l2cap_chan_del. This means that these locks are acquired in unexpected order, which leads to potential deadlock:
l2cap_chan_lock(c)
mutex_lock(&conn->chan_lock)

This patch releases chan->lock before acquiring the conn_chan_lock to avoid the potential deadlock.

PATCH 25/91 Bluetooth: L2CAP: Add missing checks for invalid DCID

In reply to Greg Kroah-Hartman

From: Sungwoo Kim <[email protected]>

[ Upstream commit 75767213f3d9b97f63694d02260b6a49a2271876 ]

When receiving a connect response we should make sure that the DCID is within the valid range and that we don't already have another channel allocated for the same DCID.
Missing checks may violate the specification (BLUETOOTH CORE SPECIFICATION Version 5.4 | Vol 3, Part A, Page 1046).

PATCH 27/91 wifi: cfg80211: fix locking in sched scan stop work

In reply to Greg Kroah-Hartman

From: Johannes Berg <[email protected]>

[ Upstream commit 3e54ed8247c94c8bdf370bd872bd9dfe72b1b12b ]

This should use wiphy_lock() now instead of acquiring the RTNL, since cfg80211_stop_sched_scan_req() now needs that.

PATCH 30/91 selftests/bpf: Fix sockopt_sk selftest

In reply to Greg Kroah-Hartman

From: Yonghong Song <[email protected]>

[ Upstream commit 69844e335d8c22454746c7903776533d8b4ab8fa ]

Commit f4e4534850a9 ("net/netlink: fix NETLINK_LIST_MEMBERSHIPS length report") fixed NETLINK_LIST_MEMBERSHIPS length report which caused
selftest sockopt_sk failure. The failure log looks like

test_sockopt_sk:PASS:join_cgroup /sockopt_sk 0 nsec
run_test:PASS:skel_load 0 nsec
run_test:PASS:setsockopt_link 0 nsec
run_test:PASS:getsockopt_link 0 nsec
getsetsockopt:FAIL:Unexpected NETLINK_LIST_MEMBERSHIPS value unexpected Unexpected NETLINK_LIST_MEMBERSHIPS value: actual 8 != expected 4 run_test:PASS:getsetsockopt 0 nsec
#201 sockopt_sk:FAIL

In net/netlink/af_netlink.c, function netlink_getsockopt(), for NETLINK_LIST_MEMBERSHIPS, nlk->ngroups equals to 36. Before Commit f4e4534850a9, the optlen is calculated as
ALIGN(nlk->ngroups / 8, sizeof(u32)) = 4
After that commit, the optlen is
ALIGN(BITS_TO_BYTES(nlk->ngroups), sizeof(u32)) = 8

Fix the test by setting the expected optlen to be 8.

PATCH 31/91 netfilter: conntrack: fix NULL pointer dereference in nf_confirm_cthelper

In reply to Greg Kroah-Hartman

From: Tijs Van Buggenhout <[email protected]>

[ Upstream commit e1f543dc660b44618a1bd72ddb4ca0828a95f7ad ]

An nf_conntrack_helper from nf_conn_help may become NULL after DNAT.

Observed when TCP port 1720 (Q931_PORT), associated with h323 conntrack helper, is DNAT'ed to another destination port (e.g. 1730), while nfqueue is being used for final acceptance (e.g. snort).

This happenned after transition from kernel 4.14 to 5.10.161.

Workarounds:
* keep the same port (1720) in DNAT
* disable nfqueue
* disable/unload h323 NAT helper

PATCH 32/91 netfilter: ipset: Add schedule point in call_ad().

In reply to Greg Kroah-Hartman

From: Kuniyuki Iwashima <[email protected]>

[ Upstream commit 24e227896bbf003165e006732dccb3516f87f88e ]

syzkaller found a repro that causes Hung Task [0] with ipset. The repro first creates an ipset and then tries to delete a large number of IPs from the ipset concurrently:

IPSET_ATTR_IPADDR_IPV4 : 172.20.20.187
IPSET_ATTR_CIDR : 2

The first deleting thread hogs a CPU with nfnl_lock(NFNL_SUBSYS_IPSET) held, and other threads wait for it to be released.

Previously, the same issue existed in set->variant->uadt() that could run so long under ip_set_lock(set). Commit 5e29dc36bd5e ("netfilter: ipset:
Rework long task execution when adding/deleting entries") tried to fix it, but the issue still exists in the caller with another mutex.

While adding/deleting many IPs, we should release the CPU periodically to prevent someone from abusing ipset to hang the system.

Note we need to increment the ipset's refcnt to prevent the ipset from being destroyed while rescheduling.

The CmprI and CmprE fields indicate the number of prefix octets that are shared with the IPv6 Destination Address. When CmprI or CmprE is not 0, Addresses[1..n] are compressed as follows:

1..n-1 : (16 - CmprI) bytes

       n : (16 - CmprE) bytes

Segments Left indicates the number of route segments remaining. When the value is not zero, the SRH is forwarded to the next hop. Its address is extracted from Addresses[n - Segment Left + 1] and swapped with IPv6 Destination Address.

When Segment Left is greater than or equal to 2, the size of SRH is not changed because Addresses[1..n-1] are decompressed and recompressed with CmprI.

OTOH, when Segment Left changes from 1 to 0, the new SRH could have a different size because Addresses[1..n-1] are decompressed with CmprI and recompressed with CmprE.

Let's say CmprI is 15 and CmprE is 0. When we receive SRH with Segment Left >= 2, Addresses[1..n-1] have 1 byte for each, and Addresses[n] has 16 bytes. When Segment Left is 1, Addresses[1..n-1] is decompressed to 16 bytes and not recompressed. Finally, the new SRH will need more room in the header, and the size is (16 - 1) * (n - 1) bytes.

Here the max value of n is 255 as Segment Left is u8, so in the worst case, we have to allocate 3825 bytes in the skb headroom. However, now we only allocate a small fixed buffer that is IPV6_RPL_SRH_WORST_SWAP_SIZE (16 + 7 bytes). If the decompressed size overflows the room, skb_push() hits BUG() below [0].

Instead of allocating the fixed buffer for every packet, let's allocate enough headroom only when we receive SRH with Segment Left 1.

PATCH 34/91 rfs: annotate lockless accesses to sk->sk_rxhash

In reply to Greg Kroah-Hartman

From: Eric Dumazet <[email protected]>

[ Upstream commit 1e5c647c3f6d4f8497dedcd226204e1880e0ffb3 ]

Add READ_ONCE()/WRITE_ONCE() on accesses to sk->sk_rxhash.

This also prevents a (smart ?) compiler to remove the condition in:

if (sk->sk_rxhash != newval)

	sk->sk_rxhash = newval;

We need the condition to avoid dirtying a shared cache line.

PATCH 36/91 drm/i915/selftests: Increase timeout for live_parallel_switch

From: Akeem G Abodunrin <[email protected]>

[ Upstream commit 373269ae6f90bbbe945abde4c0811a991a27901a ]

With GuC submission, it takes a little bit longer switching contexts among all available engines simultaneously, when running live_parallel_switch subtest. Increase the timeout.

PATCH 37/91 drm/i915/selftests: Stop using kthread_stop()

In reply to Greg Kroah-Hartman

From: Tvrtko Ursulin <[email protected]>

[ Upstream commit 6407cf533217e09dfd895e64984c3f1ee3802373 ]

Since a7c01fa93aeb ("signal: break out of wait loops on kthread_stop()") kthread_stop() started asserting a pending signal which wreaks havoc with a few of our selftests. Mainly because they are not fully expecting to handle signals, but also cutting the intended test runtimes short due signal_pending() now returning true (via __igt_timeout), which therefore breaks both the patterns of:

kthread_run()
..sleep for igt_timeout_ms to allow test to exercise stuff.. kthread_stop()

And check for errors recorded in the thread.

And also:

Main thread | Test thread
---------------+------------------------------
kthread_run() |
kthread_stop() | do stuff until __igt_timeout
| -- exits early due signal --

Where this kthread_stop() was assume would have a "join" semantics, which it would have had if not the new signal assertion issue.

To recap, threads are now likely to catch a previously impossible ERESTARTSYS or EINTR, marking the test as failed, or have a pointlessly short run time.

To work around this start using kthread_work(er) API which provides an explicit way of waiting for threads to exit. And for cases where parent controls the test duration we add explicit signaling which threads will now use instead of relying on kthread_should_stop().

PATCH 38/91 drm/i915/selftests: Add some missing error propagation

In reply to Greg Kroah-Hartman

From: Tvrtko Ursulin <[email protected]>

[ Upstream commit 79d0150d2d983a4f6efee676cea06027f586fcd0 ]

Add some missing error propagation in live_parallel_switch.

To avoid needlessly burdening the various backport processes, note I am not marking it as a fix against any patches and not copying stable since it is debug/selftests only code.

PATCH 39/91 net: sched: move rtm_tca_policy declaration to include file

In reply to Greg Kroah-Hartman

From: Eric Dumazet <[email protected]>

[ Upstream commit 886bc7d6ed3357975c5f1d3c784da96000d4bbb4 ]

rtm_tca_policy is used from net/sched/sch_api.c and net/sched/cls_api.c, thus should be declared in an include file.

This fixes the following sparse warning:

PATCH 42/91 bpf: Add extra path pointer check to d_path helper

In reply to Greg Kroah-Hartman

From: Jiri Olsa <[email protected]>

[ Upstream commit f46fab0e36e611a2389d3843f34658c849b6bd60 ]

Anastasios reported crash on stable 5.15 kernel with following BPF attached to lsm hook:

  SEC("lsm.s/bprm_creds_for_exec")
  int BPF_PROG(bprm_creds_for_exec, struct linux_binprm *bprm)
  {
          struct path *path = &bprm->executable->f_path;
          char p[128] = { 0 };
          bpf_d_path(path, p, 128);
          return 0;

}

But bprm->executable can be NULL, so bpf_d_path call will crash:

It's problem for all stable trees with bpf_d_path helper, which was added in 5.9.

This issue is fixed in current bpf code, where we identify and mark trusted pointers, so the above code would fail even to load.

For the sake of the stable trees and to workaround potentially broken verifier in the future, adding the code that reads the path object from the passed pointer and verifies it's valid in kernel space.

PATCH 43/91 lib: cpu_rmap: Fix potential use-after-free in irq_cpu_rmap_release()

PATCH 44/91 bnxt_en: Dont issue AP reset during ethtools reset operation

From: Sreekanth Reddy <[email protected]>

[ Upstream commit 1d997801c7cc6a7f542e46d5a6bf16f893ad3fe9 ]

Only older NIC controller's firmware uses the PROC AP reset type. Firmware on 5731X/5741X and newer chips does not support this reset type. When bnxt_reset() issues a series of resets, this PROC AP reset may actually fail on these newer chips because the firmware is not ready to accept this unsupported command yet. Avoid this unnecessary error by skipping this reset type on chips that don't support it.

PATCH 45/91 bnxt_en: Query default VLAN before VNIC setup on a VF

In reply to Greg Kroah-Hartman

From: Somnath Kotur <[email protected]>

[ Upstream commit 1a9e4f501bc6ff1b6ecb60df54fbf2b54db43bfe ]

We need to call bnxt_hwrm_func_qcfg() on a VF to query the default VLAN that may be setup by the PF. If a default VLAN is enabled, the VF cannot support VLAN acceleration on the receive side and the VNIC must be setup to strip out the default VLAN tag. If a default VLAN is not enabled, the VF can support VLAN acceleration on the receive side. The VNIC should be set up to strip or not strip the VLAN based on the RX VLAN acceleration setting.

Without this call to determine the default VLAN before calling bnxt_setup_vnic(), the VNIC may not be set up correctly. For example, bnxt_setup_vnic() may set up to strip the VLAN tag based on stale default VLAN information. If RX VLAN acceleration is not enabled, the VLAN tag will be incorrectly stripped and the RX data path will not work correctly.

Fixes cf6645f8ebc6 ("bnxt_en: Add function for VF driver to query default VLAN.")

PATCH 46/91 bnxt_en: Implement .set_port / .unset_port UDP tunnel callbacks

In reply to Greg Kroah-Hartman

From: Somnath Kotur <[email protected]>

[ Upstream commit 1eb4ef12591348c440ac9d6efcf7521e73cf2b10 ]

As per the new udp tunnel framework, drivers which need to know the details of a port entry (i.e. port type) when it gets deleted should use the .set_port / .unset_port callbacks.

Implementing the current .udp_tunnel_sync callback would mean that the deleted tunnel port entry would be all zeros. This used to work on older firmware because it would not check the input when deleting a tunnel port. With newer firmware, the delete will now fail and subsequent tunnel port allocation will fail as a result.

PATCH 47/91 batman-adv: Broken sync while rescheduling delayed work

In reply to Greg Kroah-Hartman

From: Vladislav Efanov <[email protected]>

commit abac3ac97fe8734b620e7322a116450d7f90aa43 upstream.

Syzkaller got a lot of crashes like:

KASAN: use-after-free Write in *_timers*

All of these crashes point to the same memory area:

The buggy address belongs to the object at ffff88801f870000
 which belongs to the cache kmalloc-8k of size 8192

The buggy address is located 5320 bytes inside of
8192-byte region [ffff88801f870000, ffff88801f872000)

This area belongs to :

        batadv_priv->batadv_priv_dat->delayed_work->timer_list

The reason for these issues is the lack of synchronization. Delayed work (batadv_dat_purge) schedules new timer/work while the device is being deleted. As the result new timer/delayed work is set after cancel_delayed_work_sync() was called. So after the device is freed the timer list contains pointer to already freed memory.

Found by Linux Verification Center (linuxtesting.org) with syzkaller.

PATCH 48/91 Input: xpad - delete a Razer DeathAdder mouse VID/PID entry

In reply to Greg Kroah-Hartman

From: Ismael Ferreras Morezuelas <[email protected]>

commit feee70f4568650cf44c573488798ffc0a2faeea3 upstream.

While doing my research to improve the xpad device names I noticed that the 1532:0037 VID/PID seems to be used by the DeathAdder 2013, so that Razer Sabertooth instance looked wrong and very suspect to me. I didn't see any mention in the official drivers, either.

After doing more research, it turns out that the xpad list is used by many other projects (like Steam) as-is [1], this issue was reported [2] and Valve/Sam Lantinga fixed it [3]:

[1]: https://github.com/libsdl-org/SDL/blob/dcc5eef0e2395854b254ea2873a4899edab347c6/src/joystick/controller_type.h#L251
[2]: https://steamcommunity.com/app/353380/discussions/0/1743392486228754770/
[3]: https://hg.libsdl.org/SDL/rev/29809f6f0271

(With multiple Internet users reporting similar issues, not linked here)

After not being able to find the correct VID/PID combination anywhere on the Internet and not receiving any reply from Razer support I did some additional detective work, it seems like it presents itself as "Razer Sabertooth Gaming Controller (XBOX360)", code 1689:FE00.

Leaving us with this:
* Razer Sabertooth (1689:fe00)
* Razer Sabertooth Elite (24c6:5d04)
* Razer DeathAdder 2013 (1532:0037) [note: not a gamepad]

So, to sum things up; remove this conflicting/duplicate entry:

{ 0x1532, 0x0037, "Razer Sabertooth", 0, XTYPE_XBOX360 },

As the real/correct one is already present there, even if the Internet as a whole insists on presenting it as the Razer Sabertooth Elite, which (by all accounts) is not:

{ 0x1689, 0xfe00, "Razer Sabertooth", 0, XTYPE_XBOX360 },

Actual change in SDL2 referencing this kernel issue:
https://github.com/libsdl-org/SDL/commit/e5e54169754ca5d3e86339d968b20126d9da0a15

PATCH 50/91 Input: fix open count when closing inhibited device

In reply to Greg Kroah-Hartman

From: Dmitry Torokhov <[email protected]>

commit 978134c4b192ed04ecf699be3e1b4d23b5d20457 upstream.

Because the kernel increments device's open count in input_open_device() even if device is inhibited, the counter should always be decremented in input_close_device() to keep it balanced.

PATCH 58/91 can: j1939: j1939_sk_send_loop_abort(): improved error queue handling in J1939 Socket

In reply to Greg Kroah-Hartman

From: Oleksij Rempel <[email protected]>

commit 2a84aea80e925ecba6349090559754f8e8eb68ef upstream.

This patch addresses an issue within the j1939_sk_send_loop_abort() function in the j1939/socket.c file, specifically in the context of Transport Protocol (TP) sessions.

Without this patch, when a TP session is initiated and a Clear To Send (CTS) frame is received from the remote side requesting one data packet, the kernel dispatches the first Data Transport (DT) frame and then waits for the next CTS. If the remote side doesn't respond with another CTS, the kernel aborts due to a timeout. This leads to the user-space receiving an EPOLLERR on the socket, and the socket becomes active.

However, when trying to read the error queue from the socket with sock.recvmsg(, , socket.MSG_ERRQUEUE), it returns -EAGAIN, given that the socket is non-blocking. This situation results in an infinite loop: the user-space repeatedly calls epoll(), epoll() returns the socket file descriptor with EPOLLERR, but the socket then blocks on the recv() of ERRQUEUE.

This patch introduces an additional check for the J1939_SOCK_ERRQUEUE flag within the j1939_sk_send_loop_abort() function. If the flag is set, it indicates that the application has subscribed to receive error queue messages. In such cases, the kernel can communicate the current transfer state via the error queue. This allows for the function to return early, preventing the unnecessary setting of the socket into an error state, and breaking the infinite loop. It is crucial to note that a socket error is only needed if the application isn't using the error queue, as, without it, the application wouldn't be aware of transfer issues.

PATCH 59/91 can: j1939: change j1939_netdev_lock type to mutex

In reply to Greg Kroah-Hartman

From: Fedor Pchelkin <[email protected]>

commit cd9c790de2088b0d797dc4d244b4f174f9962554 upstream.

It turns out access to j1939_can_rx_register() needs to be serialized, otherwise j1939_priv can be corrupted when parallel threads call j1939_netdev_start() and j1939_can_rx_register() fails. This issue is thoroughly covered in other commit which serializes access to j1939_can_rx_register().

Change j1939_netdev_lock type to mutex so that we do not need to remove GFP_KERNEL from can_rx_register().

j1939_netdev_lock seems to be used in normal contexts where mutex usage is not prohibited.

  j1939_priv_set(ndev, NULL)
  kfree(priv)
					j1939_sk_sock_destruct()
					j1939_priv_put() // <- uaf

To avoid this, call j1939_can_rx_register() under j1939_netdev_lock so that a concurrent thread cannot process j1939_priv before j1939_can_rx_register() returns.

PATCH 61/91 ceph: fix use-after-free bug for inodes when flushing capsnaps

In reply to Greg Kroah-Hartman

From: Xiubo Li <[email protected]>

commit 409e873ea3c1fd3079909718bbeb06ac1ec7f38b upstream.

There is a race between capsnaps flush and removing the inode from 'mdsc->snap_flush_list' list:

== Thread A == == Thread B ==
ceph_queue_cap_snap()
-> allocate 'capsnapA'
->ihold('&ci->vfs_inode')
->add 'capsnapA' to 'ci->i_cap_snaps'
->add 'ci' to 'mdsc->snap_flush_list'

    ...

== Thread C ==
ceph_flush_snaps()
->__ceph_flush_snaps()
->__send_flush_snap()

                                handle_cap_flushsnap_ack()
                                 ->iput('&ci->vfs_inode')
                                   this also will release 'ci'
                                    ...
				      == Thread D ==
                                ceph_handle_snap()
                                 ->flush_snaps()
                                  ->iterate 'mdsc->snap_flush_list'
                                   ->get the stale 'ci'

->remove 'ci' from ->ihold(&ci->vfs_inode) this
'mdsc->snap_flush_list' will WARNING

To fix this we will increase the inode's i_count ref when adding 'ci' to the 'mdsc->snap_flush_list' list.

PATCH 62/91 s390/dasd: Use correct lock while counting channel queue length

In reply to Greg Kroah-Hartman

From: Jan Höppner <[email protected]>

commit ccc45cb4e7271c74dbb27776ae8f73d84557f5c6 upstream.

The lock around counting the channel queue length in the BIODASDINFO ioctl was incorrectly changed to the dasd_block->queue_lock with commit 583d6535cb9d ("dasd: remove dead code"). This can lead to endless list iterations and a subsequent crash.

The queue_lock is supposed to be used only for queue lists belonging to dasd_block. For dasd_device related queue lists the ccwdev lock must be used.

Fix the mentioned issues by correctly using the ccwdev lock instead of the queue lock.

PATCH 64/91 Bluetooth: hci_qca: fix debugfs registration

In reply to Greg Kroah-Hartman

From: Johan Hovold <[email protected]>

commit 47c5d829a3e326b7395352a10fc8a6effe7afa15 upstream.

Since commit 3e4be65eb82c ("Bluetooth: hci_qca: Add poweroff support during hci down for wcn3990"), the setup callback which registers the debugfs interface can be called multiple times.

This specifically leads to the following error when powering on the controller:

debugfs: Directory 'ibs' with parent 'hci0' already present!

Add a driver flag to avoid trying to register the debugfs interface more than once.

Fixes 3e4be65eb82c ("Bluetooth: hci_qca: Add poweroff support during hci down for wcn3990")

PATCH 65/91 tee: amdtee: Add return_origin to struct tee_cmd_load_ta

In reply to Greg Kroah-Hartman

From: Rijo Thomas <[email protected]>

commit 436eeae0411acdfc54521ddea80ee76d4ae8a7ea upstream.

After TEE has completed processing of TEE_CMD_ID_LOAD_TA, set proper value in 'return_origin' argument passed by open_session() call. To do so, add 'return_origin' field to the structure tee_cmd_load_ta. The Trusted OS shall update return_origin as part of TEE processing.

This change to 'struct tee_cmd_load_ta' interface requires a similar update in AMD-TEE Trusted OS's TEE_CMD_ID_LOAD_TA interface.

This patch has been verified on Phoenix Birman setup. On older APUs, return_origin value will be 0.

PATCH 67/91 rbd: get snapshot context after exclusive lock is ensured to be held

In reply to Greg Kroah-Hartman

From: Ilya Dryomov <[email protected]>

commit 870611e4877eff1e8413c3fb92a585e45d5291f6 upstream.

Move capturing the snapshot context into the image request state machine, after exclusive lock is ensured to be held for the duration of dealing with the image request. This is needed to ensure correctness of fast-diff states (OBJECT_EXISTS vs OBJECT_EXISTS_CLEAN) and object deltas computed based off of them. Otherwise the object map that is forked for the snapshot isn't guaranteed to accurately reflect the contents of the snapshot when the snapshot is taken under I/O. This breaks differential backup and snapshot-based mirroring use cases with fast-diff enabled: since some object deltas may be incomplete, the destination image may get corrupted.

PATCH 69/91 usb: usbfs: Enforce page requirements for mmap

In reply to Greg Kroah-Hartman

From: Ruihan Li <[email protected]>

commit 0143d148d1e882fb1538dc9974c94d63961719b9 upstream.

The current implementation of usbdev_mmap uses usb_alloc_coherent to allocate memory pages that will later be mapped into the user space. Meanwhile, usb_alloc_coherent employs three different methods to allocate memory, as outlined below:
* If hcd->localmem_pool is non-null, it uses gen_pool_dma_alloc to allocate memory;
* If DMA is not available, it uses kmalloc to allocate memory;
* Otherwise, it uses dma_alloc_coherent.

However, it should be noted that gen_pool_dma_alloc does not guarantee that the resulting memory will be page-aligned. Furthermore, trying to map slab pages (i.e., memory allocated by kmalloc) into the user space is not resonable and can lead to problems, such as a type confusion bug when PAGE_TABLE_CHECK=y [1].

To address these issues, this patch introduces hcd_alloc_coherent_pages, which addresses the above two problems. Specifically, hcd_alloc_coherent_pages uses gen_pool_dma_alloc_align instead of gen_pool_dma_alloc to ensure that the memory is page-aligned. To replace kmalloc, hcd_alloc_coherent_pages directly allocates pages by calling __get_free_pages.

PATCH 70/91 usb: usbfs: Use consistent mmap functions

In reply to Greg Kroah-Hartman

From: Ruihan Li <[email protected]>

commit d0b861653f8c16839c3035875b556afc4472f941 upstream.

When hcd->localmem_pool is non-null, localmem_pool is used to allocate DMA memory. In this case, the dma address will be properly returned (in dma_handle), and dma_mmap_coherent should be used to map this memory into the user space. However, the current implementation uses pfn_remap_range, which is supposed to map normal pages.

Instead of repeating the logic in the memory allocation function, this patch introduces a more robust solution. Here, the type of allocated memory is checked by testing whether dma_handle is properly set. If dma_handle is properly returned, it means some DMA pages are allocated and dma_mmap_coherent should be used to map them. Otherwise, normal pages are allocated and pfn_remap_range should be called. This ensures that the correct mmap functions are used consistently, independently with logic details that determine which type of memory gets allocated.

PATCH 73/91 arm64: dts: qcom: sc7180-lite: Fix SDRAM freq for misidentified sc7180-lite boards

In reply to Greg Kroah-Hartman

From: Douglas Anderson <[email protected]>

[ Upstream commit 3a735530c159b75e1402c08abe1ba4eb99a1f7a3 ]

In general, the three SKUs of sc7180 (lite, normal, and pro) are handled dynamically.

The cpufreq table in sc7180.dtsi includes the superset of all CPU frequencies. The "qcom-cpufreq-hw" driver in Linux shows that we can dynamically detect which frequencies are actually available on the currently running CPU and then we can just enable those ones.

The GPU is similarly dynamic. The nvmem has a fuse in it (see "gpu_speed_bin" in sc7180.dtsi) that the GPU driver can use to figure out which frequencies to enable.

There is one part, however, that is not so dynamic. The way SDRAM frequency works in sc7180 is that it's tied to cpufreq. At the busiest cpufreq operating points we'll pick the top supported SDRAM frequency. They ramp down together.

For the "pro" SKU of sc7180, we only enable one extra cpufreq step. That extra cpufreq step runs SDRAM at the same speed as the step below. Thus, for normal and pro things are OK. There is no sc7180-pro device tree snippet.

For the "lite" SKU if sc7180, however, things aren't so easy. The "lite" SKU drops 3 cpufreq entries but can still run SDRAM at max frequency. That messed things up with the whole scheme. This is why we added the "sc7180-lite" fragment in commit 8fd01e01fd6f ("arm64: dts:
qcom: sc7180-lite: Tweak DDR/L3 scaling on SC7180-lite").

When the lite scheme came about, it was agreed that the WiFi SKUs of lazor would _always_ be "lite" and would, in fact, be the only "lite" devices. Unfortunately, this decision changed and folks didn't realize that it would be a problem. Specifically, some later lazor WiFi-only devices were built with "pro" CPUs.

Building WiFi-only lazor with "pro" CPUs isn't the end of the world. The SDRAM will ramp up a little sooner than it otherwise would, but aside from a small power hit things work OK. One problem, though, is that the SDRAM scaling becomes a bit quirky. Specifically, with the current tables we'll max out SDRAM frequency at 2.1GHz but then _lower_ it at 2.2GHz / 2.3GHz only to raise it back to max for 2.4GHz and 2.55GHz.

Let's at least fix this so that the SDRAM frequency doesn't go down in that quirky way. On true "lite" SKUs this change will be a no-op because the operating points we're touching are disabled. This change is only useful when a board that thinks it has a "lite" CPU actually has a "normal" or "pro" one stuffed.

PATCH 75/91 arm64: dts: imx8-ss-dma: assign default clock rate for lpuarts

In reply to Greg Kroah-Hartman

From: Shenwei Wang <[email protected]>

[ Upstream commit ca50d7765587fe0a8351a6e8d9742cfd4811d925 ]

Add the assigned-clocks and assigned-clock-rates properties for the LPUARTx nodes. Without these properties, the default clock rate used would be 0, which can cause the UART ports to fail when open.

Fixes 35f4e9d7530f ("arm64: dts: imx8: split adma ss into dma and audio ss")

PATCH 76/91 ASoC: mediatek: mt8195-afe-pcm: Convert to platform remove callback returning void

In reply to Greg Kroah-Hartman

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

[ Upstream commit 6461fee68064ba970e3ba90241fe5f5e038aa9d4 ]

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void.

Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

Stable-dep-of: dc93f0dcb436 ("ASoC: mediatek: mt8195: fix use-after-free in driver remove path")

PATCH 77/91 ASoC: mediatek: mt8195: fix use-after-free in driver remove path

In reply to Greg Kroah-Hartman

From: Trevor Wu <[email protected]>

[ Upstream commit dc93f0dcb436dfd24a06c5b3c0f4c5cd9296e8e5 ]

During mt8195_afe_init_clock(), mt8195_audsys_clk_register() was called followed by several other devm functions. At mt8195_afe_deinit_clock() located at mt8195_afe_pcm_dev_remove(), mt8195_audsys_clk_unregister() was called.

However, there was an issue with the order in which these functions were called. Specifically, the remove callback of platform_driver was called before devres released the resource, resulting in a use-after-free issue during remove time.

At probe time, the order of calls was:
1. mt8195_audsys_clk_register
2. afe_priv->clk = devm_kcalloc
3. afe_priv->clk[i] = devm_clk_get

At remove time, the order of calls was:
1. mt8195_audsys_clk_unregister
3. free afe_priv->clk[i]
2. free afe_priv->clk

To resolve the problem, we can utilize devm_add_action_or_reset() in mt8195_audsys_clk_register() so that the remove order can be changed to 3->2->1.

PATCH 78/91 arm64: dts: imx8mn-beacon: Fix SPI CS pinmux

The final production baseboard had a different chip select than earlier prototype boards. When the newer board was released, the SPI stopped working because the wrong pin was used in the device tree and conflicted with the UART RTS. Fix the pinmux for production boards.

PATCH 79/91 i2c: mv64xxx: Fix reading invalid status value in atomic mode

In reply to Greg Kroah-Hartman

From: Marek Behún <[email protected]>

[ Upstream commit 5578d0a79b6430fa1543640dd6f2d397d0886ce7 ]

There seems to be a bug within the mv64xxx I2C controller, wherein the status register may not necessarily contain valid value immediately after the IFLG flag is set in the control register.

My theory is that the controller:
- first sets the IFLG in control register
- then updates the status register
- then raises an interrupt

This may sometime cause weird bugs when in atomic mode, since in this mode we do not wait for an interrupt, but instead we poll the control register for IFLG and read status register immediately after.

I encountered -ENXIO from mv64xxx_i2c_fsm() due to this issue when using this driver in atomic mode.

Note that I've only seen this issue on Armada 385, I don't know whether other SOCs with this controller are also affected. Also note that this fix has been in U-Boot for over 4 years [1] without anybody complaining, so it should not cause regressions.

PATCH 81/91 i2c: sprd: Delete i2c adapter in .removes error path

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

[ Upstream commit ca0aa17f2db3468fd017038d23a78e17388e2f67 ]

If pm runtime resume fails the .remove callback used to exit early. This resulted in an error message by the driver core but the device gets removed anyhow. This lets the registered i2c adapter stay around with an unbound parent device.

So only skip clk disabling if resume failed, but do delete the adapter.

PATCH 83/91 riscv: fix kprobe __user string arg print fault issue

In reply to Greg Kroah-Hartman

From: Ruan Jinjie <[email protected]>

[ Upstream commit 99a670b2069c725a7b50318aa681d9cae8f89325 ]

On riscv qemu platform, when add kprobe event on do_sys_open() to show filename string arg, it just print fault as follow:

echo 'p:myprobe do_sys_open dfd=$arg1 filename=+0($arg2):string flags=$arg3 mode=$arg4' > kprobe_events

bash-166 [000] ...1. 360.195367: myprobe: (do_sys_open+0x0/0x84)

As riscv do not select ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE, the +0($arg2) addr is processed as a kernel address though it is a userspace address, cause the above filename=(fault) print. So select ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE to avoid the issue, after that the kprobe trace is ok as below:

Syzkaller hits a kernel WARN when the first character of the dev name provided is NULL. Solution is to add a NULL check before calling cdev_device_add() in vduse_create_dev().

PATCH 88/91 ext4: only check dquot_initialize_needed() when debugging

In reply to Greg Kroah-Hartman

From: Theodore Ts'o <[email protected]>

commit dea9d8f7643fab07bf89a1155f1f94f37d096a5e upstream.

ext4_xattr_block_set() relies on its caller to call dquot_initialize() on the inode. To assure that this has happened there are WARN_ON checks. Unfortunately, this is subject to false positives if there is an antagonist thread which is flipping the file system at high rates between r/o and rw. So only do the check if EXT4_XATTR_DEBUG is enabled.

 </TASK>

The fuzzed image contains an AGF with an obviously garbage agf_refcount_level value of 32, and a dirty log with a buffer log item for that AGF. The ondisk AGF has a higher LSN than the recovered log item. xlog_recover_buf_commit_pass2 reads the buffer, compares the LSNs, and decides to skip replay because the ondisk buffer appears to be newer.

Unfortunately, the ondisk buffer is corrupt, but recovery just read the buffer with no buffer ops specified:

	error = xfs_buf_read(mp->m_ddev_targp, buf_f->blf_blkno,
			buf_f->blf_len, buf_flags, &bp, NULL);

Skipping the buffer leaves its contents in memory unverified. This sets us up for a kernel crash because xfs_refcount_recover_cow_leftovers reads the buffer (which is still around in XBF_DONE state, so no read verification) and creates a refcountbt cursor of height 32. This is impossible so we run off the end of the cursor object and crash.

Fix this by invoking the verifier on all skipped buffers and aborting log recovery if the ondisk buffer is corrupt. It might be smarter to force replay the log item atop the buffer and then see if it'll pass the write verifier (like ext4 does) but for now let's go with the conservative option where we stop immediately.

Ben reports that this should not have been backported to the older kernels as the rest of the macro is not empty. It was a clean-up patch in 6.4-rc1 only, it did not add new device ids.
