PATCH 1/108 igc: Fix use-after-free error during reset

From: Vinicius Costa Gomes <[email protected]>

[ Upstream commit 56ea7ed103b46970e171eb1c95916f393d64eeff ]

Cleans the next descriptor to watch (next_to_watch) when cleaning the TX ring.

Failure to do so can cause invalid memory accesses. If igc_poll() runs while the controller is being reset this can lead to the driver try to free a skb that was already freed.

PATCH 2/108 igb: Fix use-after-free error during reset

In reply to Greg Kroah-Hartman

From: Vinicius Costa Gomes <[email protected]>

[ Upstream commit 7b292608db23ccbbfbfa50cdb155d01725d7a52e ]

Cleans the next descriptor to watch (next_to_watch) when cleaning the TX ring.

Failure to do so can cause invalid memory accesses. If igb_poll() runs while the controller is reset this can lead to the driver try to free a skb that was already freed.

(The crash is harder to reproduce with the igb driver, but the same potential problem exists as the code is identical to igc)

Fixes 7cc6fd4c60f2 ("igb: Don't bother clearing Tx buffer_info in igb_clean_tx_ring")

However, it's not exactly the same mechanism. On IPv4, all packets coming from an interface, which has disable_policy set, bypass the policy check. For ipv6, this is done only for local packets, ie for packets destinated to an address configured on the incoming interface.

Let's align ipv6 with ipv4 so that the 'disable_policy' sysctl has the same effect for both protocols.

My first approach was to create a new kind of route cache entries, to be able to set DST_NOPOLICY without modifying routes. This would have added a lot of code. Because the local delivery path is already handled, I choose to focus on the forwarding path to minimize code churn.

Fixes df789fe75206 ("ipv6: Provide ipv6 version of "disable_policy" sysctl")

PATCH 15/108 selftests: icmp_redirect: remove from checking for IPv6 route get

In reply to Greg Kroah-Hartman

From: Hangbin Liu <[email protected]>

[ Upstream commit 24b671aad4eae423e1abf5b7f08d9a5235458b8d ]

If the kernel doesn't enable option CONFIG_IPV6_SUBTREES, the RTA_SRC info will not be exported to userspace in rt6_fill_node(). And ip cmd will not print "from ::" to the route output. So remove this check.

PATCH 16/108 selftests: icmp_redirect: IPv6 PMTU info should be cleared after redirect

In reply to Greg Kroah-Hartman

From: Hangbin Liu <[email protected]>

[ Upstream commit 0e02bf5de46ae30074a2e1a8194a422a84482a1a ]

After redirecting, it's already a new path. So the old PMTU info should be cleared. The IPv6 test "mtu exception plus redirect" should only has redirect info without old PMTU.

The IPv4 test can not be changed because of legacy.

PATCH 17/108 pwm: sprd: Ensure configuring period and duty_cycle isnt wrongly skipped

In reply to Greg Kroah-Hartman

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

[ Upstream commit 65e2e6c1c20104ed19060a38f4edbf14e9f9a9a5 ]

As the last call to sprd_pwm_apply() might have exited early if state->enabled was false, the values for period and duty_cycle stored in pwm->state might not have been written to hardware and it must be ensured that they are configured before enabling the PWM.

PATCH 18/108 cxgb4: fix IRQ free race during driver unload

In reply to Greg Kroah-Hartman

From: Shahjada Abul Husain <[email protected]>

[ Upstream commit 015fe6fd29c4b9ac0f61b8c4455ef88e6018b9cc ]

IRQs are requested during driver's ndo_open() and then later freed up in disable_interrupts() during driver unload. A race exists where driver can set the CXGB4_FULL_INIT_DONE flag in ndo_open() after the disable_interrupts() in driver unload path checks it, and hence misses calling free_irq().

Fix by unregistering netdevice first and sync with driver's ndo_open(). This ensures disable_interrupts() checks the flag correctly and frees up the IRQs properly.

Fixes b37987e8db5f ("cxgb4: Disable interrupts and napi before unregistering netdev")

PATCH 19/108 nvme-pci: do not call nvme_dev_remove_admin from nvme_remove

In reply to Greg Kroah-Hartman

From: Casey Chen <[email protected]>

[ Upstream commit 251ef6f71be2adfd09546a26643426fe62585173 ]

nvme_dev_remove_admin could free dev->admin_q and the admin_tagset while they are being accessed by nvme_dev_disable(), which can be called by nvme_reset_work via nvme_remove_dead_ctrl.

Commit cb4bfda62afa ("nvme-pci: fix hot removal during error handling") intended to avoid requests being stuck on a removed controller by killing the admin queue. But the later fix c8e9e9b7646e ("nvme-pci: unquiesce admin queue on shutdown"), together with nvme_dev_disable(dev, true) right before nvme_dev_remove_admin() could help dispatch requests and fail them early, so we don't need nvme_dev_remove_admin() any more.

PATCH 30/108 spi: imx: add a check for speed_hz before calculating the clock

In reply to Greg Kroah-Hartman

From: Clark Wang <[email protected]>

[ Upstream commit 4df2f5e1372e9eec8f9e1b4a3025b9be23487d36 ]

When some drivers use spi to send data, spi_transfer->speed_hz is not assigned. If spidev->max_speed_hz is not assigned as well, it will cause an error in configuring the clock.
Add a check for these two values before configuring the clock. An error will be returned when they are not assigned.

PATCH 31/108 spi: stm32: Use dma_request_chan() instead dma_request_slave_channel()

In reply to Greg Kroah-Hartman

From: Peter Ujfalusi <[email protected]>

[ Upstream commit 0a454258febb73e4c60d7f5d9a02d1a8c64fdfb8 ]

dma_request_slave_channel() is a wrapper on top of dma_request_chan() eating up the error code.

By using dma_request_chan() directly the driver can support deferred probing against DMA.

PATCH 32/108 spi: stm32: fixes pm_runtime calls in probe/remove

In reply to Greg Kroah-Hartman

From: Alain Volmat <[email protected]>

[ Upstream commit 7999d2555c9f879d006ea8469d74db9cdb038af0 ]

Add pm_runtime calls in probe/probe error path and remove in order to be consistent in all places in ordering and ensure that pm_runtime is disabled prior to resources used by the SPI controller.

This patch also fixes the 2 following warnings on driver remove:

WARNING: CPU: 0 PID: 743 at drivers/clk/clk.c:594 clk_core_disable_lock+0x18/0x24
WARNING: CPU: 0 PID: 743 at drivers/clk/clk.c:476 clk_unprepare+0x24/0x2c

PATCH 34/108 regulator: hi6421: Fix getting wrong drvdata

In reply to Greg Kroah-Hartman

From: Axel Lin <[email protected]>

[ Upstream commit 1c73daee4bf30ccdff5e86dc400daa6f74735da5 ]

Since config.dev = pdev->dev.parent in current code, so dev_get_drvdata(rdev->dev.parent) call in hi6421_regulator_enable returns the drvdata of the mfd device rather than the regulator. Fix it.

This was broken while converting to use simplified DT parsing because the config.dev changed from pdev->dev to pdev->dev.parent for parsing the parent's of_node.

Fixes 29dc269a85ef ("regulator: hi6421: Convert to use simplified DT parsing")

PATCH 36/108 ASoC: rt5631: Fix regcache sync errors on resume

In reply to Greg Kroah-Hartman

From: Maxim Schwalm <[email protected]>

[ Upstream commit c71f78a662611fe2c67f3155da19b0eff0f29762 ]

The ALC5631 does not like multi-write accesses, avoid them. This fixes:

rt5631 4-001a: Unable to sync registers 0x3a-0x3c. -121

errors on resume from suspend (and all registers after the registers in the error not being synced).

Inspired by commit 2d30e9494f1e ("ASoC: rt5651: Fix regcache sync errors on resume") from Hans de Geode, which fixed the same errors on ALC5651.

PATCH 37/108 liquidio: Fix unintentional sign extension issue on left shift of u16

In reply to Greg Kroah-Hartman

From: Colin Ian King <[email protected]>

[ Upstream commit e7efc2ce3d0789cd7c21b70ff00cd7838d382639 ]

Shifting the u16 integer oct->pcie_port by CN23XX_PKT_INPUT_CTL_MAC_NUM_POS
(29) bits will be promoted to a 32 bit signed int and then sign-extended to a u64. In the cases where oct->pcie_port where bit 2 is set (e.g. 3..7) the shifted value will be sign extended and the top 32 bits of the result will be set.

Fix this by casting the u16 values to a u64 before the 29 bit left shift.

Addresses-Coverity: ("Unintended sign extension")

Fixes 3451b97cce2d ("liquidio: CN23XX register setup")

PATCH 38/108 s390/bpf: Perform r1 range checking before accessing jit->seen_reg[r1]

In reply to Greg Kroah-Hartman

From: Colin Ian King <[email protected]>

[ Upstream commit 91091656252f5d6d8c476e0c92776ce9fae7b445 ]

Currently array jit->seen_reg[r1] is being accessed before the range checking of index r1. The range changing on r1 should be performed first since it will avoid any potential out-of-range accesses on the array seen_reg[] and also it is more optimal to perform checks on r1 before fetching data from the array. Fix this by swapping the order of the checks before the array access.

PATCH 39/108 bpf, sockmap, tcp: sk_prot needs inuse_idx set for proc stats

In reply to Greg Kroah-Hartman

From: John Fastabend <[email protected]>

[ Upstream commit 228a4a7ba8e99bb9ef980b62f71e3be33f4aae69 ]

The proc socket stats use sk_prot->inuse_idx value to record inuse sock stats. We currently do not set this correctly from sockmap side. The result is reading sock stats '/proc/net/sockstat' gives incorrect values. The socket counter is incremented correctly, but because we don't set the counter correctly when we replace sk_prot we may omit the decrement.

To get the correct inuse_idx value move the core_initcall that initializes the TCP proto handlers to late_initcall. This way it is initialized after TCP has the chance to assign the inuse_idx value from the register protocol handler.

PATCH 44/108 KVM: PPC: Book3S: Fix CONFIG_TRANSACTIONAL_MEM=n crash

In reply to Greg Kroah-Hartman

From: Nicholas Piggin <[email protected]>

[ Upstream commit bd31ecf44b8e18ccb1e5f6b50f85de6922a60de3 ]

When running CPU_FTR_P9_TM_HV_ASSIST, HFSCR[TM] is set for the guest even if the host has CONFIG_TRANSACTIONAL_MEM=n, which causes it to be unprepared to handle guest exits while transactional.

Normal guests don't have a problem because the HTM capability will not be advertised, but a rogue or buggy one could crash the host.

PATCH 46/108 net: sched: fix memory leak in tcindex_partial_destroy_work

In reply to Greg Kroah-Hartman

From: Pavel Skripkin <[email protected]>

[ Upstream commit f5051bcece50140abd1a11a2d36dc3ec5484fc32 ]

Syzbot reported memory leak in tcindex_set_parms(). The problem was in non-freed perfect hash in tcindex_partial_destroy_work().

In tcindex_set_parms() new tcindex_data is allocated and some fields from old one are copied to new one, but not the perfect hash. Since tcindex_partial_destroy_work() is the destroy function for old tcindex_data, we need to free perfect hash to avoid memory leak.

PATCH 47/108 netrom: Decrease sock refcount when sock timers expire

In reply to Greg Kroah-Hartman

From: Nguyen Dinh Phi <[email protected]>

[ Upstream commit 517a16b1a88bdb6b530f48d5d153478b2552d9a8 ]

Commit 63346650c1a9 ("netrom: switch to sock timer API") switched to use sock timer API. It replaces mod_timer() by sk_reset_timer(), and del_timer() by sk_stop_timer().

Function sk_reset_timer() will increase the refcount of sock if it is called on an inactive timer, hence, in case the timer expires, we need to decrease the refcount ourselves in the handler, otherwise, the sock refcount will be unbalanced and the sock will never be freed.

PATCH 48/108 scsi: iscsi: Fix iface sysfs attr detection

In reply to Greg Kroah-Hartman

From: Mike Christie <[email protected]>

[ Upstream commit e746f3451ec7f91dcc9fd67a631239c715850a34 ]

A ISCSI_IFACE_PARAM can have the same value as a ISCSI_NET_PARAM so when iscsi_iface_attr_is_visible tries to figure out the type by just checking the value, we can collide and return the wrong type. When we call into the driver we might not match and return that we don't want attr visible in sysfs. The patch fixes this by setting the type when we figure out what the param is.

Fixes 3e0f65b34cc9 ("[SCSI] iscsi_transport: Additional parameters for network settings")

PATCH 50/108 spi: cadence: Correct initialisation of runtime PM again

In reply to Greg Kroah-Hartman

From: Marek Vasut <[email protected]>

[ Upstream commit 56912da7a68c8356df6a6740476237441b0b792a ]

The original implementation of RPM handling in probe() was mostly correct, except it failed to call pm_runtime_get_*() to activate the hardware. The subsequent fix, 734882a8bf98 ("spi: cadence: Correct initialisation of runtime PM"), breaks the implementation further, to the point where the system using this hard IP on ZynqMP hangs on boot, because it accesses hardware which is gated off.

Undo 734882a8bf98 ("spi: cadence: Correct initialisation of runtime PM") and instead add missing pm_runtime_get_noresume() and move the RPM disabling all the way to the end of probe(). That makes ZynqMP not hang on boot yet again.

Fixes 734882a8bf98 ("spi: cadence: Correct initialisation of runtime PM")

PATCH 51/108 bnxt_en: Improve bnxt_ulp_stop()/bnxt_ulp_start() call sequence.

In reply to Greg Kroah-Hartman

From: Vasundhara Volam <[email protected]>

[ Upstream commit aa46dffff452f7c6d907c4e6a0062e2c53a87fc0 ]

We call bnxt_ulp_stop() to notify the RDMA driver that some error or imminent reset is about to happen. After that we always call some variants of bnxt_close().

In the next patch, we will integrate the recently added error recovery with the RDMA driver. In response to ulp_stop, the RDMA driver may free MSIX vectors and that will also trigger bnxt_close(). To avoid bnxt_close() from being called twice, we set a new flag after ulp_stop is called. If the RDMA driver frees MSIX vectors while the new flag is set, we will not call bnxt_close(), knowing that it will happen in due course.

With this change, we must make sure that the bnxt_close() call after ulp_stop will reset IRQ. Modify bnxt_reset_task() accordingly if we call ulp_stop.

PATCH 52/108 bnxt_en: Refresh RoCE capabilities in bnxt_ulp_probe()

In reply to Greg Kroah-Hartman

From: Michael Chan <[email protected]>

[ Upstream commit 2c9f046bc377efd1f5e26e74817d5f96e9506c86 ]

The capabilities can change after firmware upgrade/downgrade, so we should get the up-to-date RoCE capabilities everytime bnxt_ulp_probe() is called.

Fixes 2151fe0830fd ("bnxt_en: Handle RESET_NOTIFY async event from firmware.")

PATCH 53/108 bnxt_en: Add missing check for BNXT_STATE_ABORT_ERR in bnxt_fw_rset_task()

From: Michael Chan <[email protected]>

In the BNXT_FW_RESET_STATE_POLL_VF state in bnxt_fw_reset_task() after all VFs have unregistered, we need to check for BNXT_STATE_ABORT_ERR after we acquire the rtnl_lock. If the flag is set, we need to abort.

PATCH 54/108 bnxt_en: Check abort error state in bnxt_half_open_nic()

In reply to Greg Kroah-Hartman

From: Somnath Kotur <[email protected]>

[ Upstream commit 11a39259ff79b74bc99f8b7c44075a2d6d5e7ab1 ]

bnxt_half_open_nic() is called during during ethtool self test and is protected by rtnl_lock. Firmware reset can be happening at the same time. Only critical portions of the entire firmware reset sequence are protected by the rtnl_lock. It is possible that bnxt_half_open_nic() can be called when the firmware reset sequence is aborting. In that case, bnxt_half_open_nic() needs to check if the ABORT_ERR flag is set and abort if it is. The ethtool self test will fail but the NIC will be brought to a consistent IF_DOWN state.

Without this patch, if bnxt_half_open_nic() were to continue in this error state, it may crash like this:

bnxt_en 0000:82:00.1 enp130s0f1np1: FW reset in progress during close, FW reset will be aborted

PATCH 56/108 net/tcp_fastopen: fix data races around tfo_active_disable_stamp

In reply to Greg Kroah-Hartman

From: Eric Dumazet <[email protected]>

[ Upstream commit 6f20c8adb1813467ea52c1296d52c4e95978cb2f ]

tfo_active_disable_stamp is read and written locklessly. We need to annotate these accesses appropriately.

Then, we need to perform the atomic_inc(tfo_active_disable_times) after the timestamp has been updated, and thus add barriers to make sure tcp_fastopen_active_should_disable() wont read a stale timestamp.

PATCH 57/108 net: hns3: fix rx VLAN offload state inconsistent issue

In reply to Greg Kroah-Hartman

From: Jian Shen <[email protected]>

[ Upstream commit bbfd4506f962e7e6fff8f37f017154a3c3791264 ]

Currently, VF doesn't enable rx VLAN offload when initializating, and PF does it for VFs. If user disable the rx VLAN offload for VF with ethtool -K, and reload the VF driver, it may cause the rx VLAN offload state being inconsistent between hardware and software.

Fixes it by enabling rx VLAN offload when VF initializing.

PATCH 58/108 net/sched: act_skbmod: Skip non-Ethernet packets

In reply to Greg Kroah-Hartman

From: Peilin Ye <[email protected]>

[ Upstream commit 727d6a8b7ef3d25080fad228b2c4a1d4da5999c6 ]

Currently tcf_skbmod_act() assumes that packets use Ethernet as their L2 protocol, which is not always the case. As an example, for CAN devices:

	$ ip link add dev vcan0 type vcan
	$ ip link set up vcan0
	$ tc qdisc add dev vcan0 root handle 1: htb
	$ tc filter add dev vcan0 parent 1: protocol ip prio 10 \
		matchall action skbmod swap mac

Doing the above silently corrupts all the packets. Do not perform skbmod actions for non-Ethernet packets.

From: Paolo Abeni <[email protected]>

[ Upstream commit 8fb4792f091e608a0a1d353dfdf07ef55a719db5 ]

While running the self-tests on a KASAN enabled kernel, I observed a slab-out-of-bounds splat very similar to the one reported in commit 821bbf79fe46 ("ipv6: Fix KASAN: slab-out-of-bounds Read in

We additionally need to take care of fib6_metrics initialization failure when the caller provides an nh.

The fix is similar, explicitly free the route instead of calling fib6_info_release on a half-initialized object.

for ((i = 0; i < 10; i++)); do
echo 1 > "$sysfs/remove"
echo 1 > /sys/bus/pci/rescan

Since the device ctrl could be updated as an non-RESETTING state by repeating probe/remove in userspace (which is a normal situation), we can replace stack dumping WARN_ON with a warnning message.

PATCH 61/108 Revert "USB: quirks: ignore remote wake-up on Fibocom L850-GL LTE modem"

In reply to Greg Kroah-Hartman

From: Vincent Palatin <[email protected]>

[ Upstream commit f3a1a937f7b240be623d989c8553a6d01465d04f ]

This reverts commit 0bd860493f81eb2a46173f6f5e44cc38331c8dbd.

While the patch was working as stated,ie preventing the L850-GL LTE modem from crashing on some U3 wake-ups due to a race condition between the host wake-up and the modem-side wake-up, when using the MBIM interface, this would force disabling the USB runtime PM on the device.

The increased power consumption is significant for LTE laptops, and given that with decently recent modem firmwares, when the modem hits the bug, it automatically recovers (ie it drops from the bus, but automatically re-enumerates after less than half a second, rather than being stuck until a power cycle as it was doing with ancient firmware), for most people, the trade-off now seems in favor of re-enabling it by default.

For people with access to the platform code, the bug can also be worked-around successfully by changing the USB3 LFPM polling off-time for the XHCI controller in the BIOS code.

general protection fault, probably for non-canonical address 0x435f5346592e4243: 0000 [#1] SMP PTI
CPU: 1 PID: 842 Comm: cat Not tainted 5.12.6+ #26
Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-1.fc33 04/01/2014
RIP: 0010:t_show+0x22/0xd0

Then reproducer was narrowed to

# cat /sys/kernel/tracing/printk_formats

Original F34 kernel with modules didn't crash.

So I started to disable options and after disabling AFS everything started working again.

The root cause is that AFS was placing char arrays content into a section full of _pointers_ to strings with predictable consequences.

Non canonical address 435f5346592e4243 is "CB.YFS_" which came from CM_NAME macro.

Steps to reproduce:

CONFIG_AFS=y
CONFIG_TRACING=y

# cat /sys/kernel/tracing/printk_formats

Fix this by the following means:

(1) Add enum->string translation tables in the event header with the AFS and YFS cache/callback manager operations listed by RPC operation ID.

(2) Modify the afs_cb_call tracepoint to print the string from the translation table rather than using the string at the afs_call name pointer.

(3) Switch translation table depending on the service we're being accessed as (AFS or YFS) in the tracepoint print clause. Will this cause problems to userspace utilities?

Note that the symbolic representation of the YFS service ID isn't available to this header, so I've put it in as a number. I'm not sure if this is the best way to do this.

(4) Remove the name wrangling (CM_NAME) macro and put the names directly into the afs_call_type structs in cmservice.c.

PATCH 63/108 r8169: Avoid duplicate sysfs entry creation error

In reply to Greg Kroah-Hartman

From: Sayanta Pattanayak <[email protected]>

[ Upstream commit e9a72f874d5b95cef0765bafc56005a50f72c5fe ]

When registering the MDIO bus for a r8169 device, we use the PCI bus/device specifier as a (seemingly) unique device identifier. However the very same BDF number can be used on another PCI segment, which makes the driver fail probing:

[ 27.544136] r8169 0002:07:00.0: enabling device (0000 -> 0003)
[ 27.559734] sysfs: cannot create duplicate filename '/class/mdio_bus/r8169-700'
....
[ 27.684858] libphy: mii_bus r8169-700 failed to register
[ 27.695602] r8169: probe of 0002:07:00.0 failed with error -22

Add the segment number to the device name to make it more unique.

This fixes operation on ARM N1SDP boards, with two boards connected together to form an SMP system, and all on-board devices showing up twice, just on different PCI segments. A similar issue would occur on large systems with many PCI slots and multiple RTL8169 NICs.

Fixes f1e911d5d0dfd ("r8169: add basic phylib support")

PATCH 65/108 sctp: update active_key for asoc when old key is being replaced

From: Xin Long <[email protected]>

[ Upstream commit 58acd10092268831e49de279446c314727101292 ]

syzbot reported a call trace:

This is an use-after-free issue caused by not updating asoc->shkey after it was replaced in the key list asoc->endpoint_shared_keys, and the old key was freed.

This patch is to fix by also updating active_key for asoc when old key is being replaced with a new one. Note that this issue doesn't exist in sctp_auth_del_key_id(), as it's not allowed to delete the active_key from the asoc.

PATCH 68/108 proc: Avoid mixing integer types in mem_rw()

From: Marcelo Henrique Cerri <[email protected]>

[ Upstream commit d238692b4b9f2c36e35af4c6e6f6da36184aeb3e ]

Use size_t when capping the count argument received by mem_rw(). Since count is size_t, using min_t(int, ...) can lead to a negative value that will later be passed to access_remote_vm(), which can cause unexpected behavior.

Since we are capping the value to at maximum PAGE_SIZE, the conversion from size_t to int when passing it to access_remote_vm() as "len" shouldn't be a problem.

PATCH 70/108 s390/ftrace: fix ftrace_update_ftrace_func implementation

In reply to Greg Kroah-Hartman

From: Vasily Gorbik <[email protected]>

commit f8c2602733c953ed7a16e060640b8e96f9d94b9b upstream.

s390 enforces DYNAMIC_FTRACE if FUNCTION_TRACER is selected. At the same time implementation of ftrace_caller is not compliant with HAVE_DYNAMIC_FTRACE since it doesn't provide implementation of ftrace_update_ftrace_func() and calls ftrace_trace_function() directly.

The subtle difference is that during ftrace code patching ftrace replaces function tracer via ftrace_update_ftrace_func() and activates it back afterwards. Unexpected direct calls to ftrace_trace_function() during ftrace code patching leads to nullptr-dereferences when tracing is activated for one of functions which are used during code patching. Those function currently are:
copy_from_kernel_nofault() copy_from_kernel_nofault_allowed()
preempt_count_sub() [with debug_defconfig] preempt_count_add() [with debug_defconfig]

From: Alexander Egorenkov <[email protected]>

commit 463f36c76fa4ec015c640ff63ccf52e7527abee0 upstream.

The DMA code section of the decompressor must be compiled with expolines if Spectre V2 mitigation has been enabled for the decompressed kernel. This is required because although the decompressor's image contains the DMA code section, it is handed over to the decompressed kernel for use.

Because the DMA code is already slow w/o expolines, use expolines always regardless whether the decompressed kernel is using them or not. This simplifies the DMA code by dropping the conditional compilation of expolines.

Fixes bf72630130c2 ("s390: use proper expoline sections for .dma code")

PATCH 72/108 ALSA: usb-audio: Add missing proc text entry for BESPOKEN type

In reply to Greg Kroah-Hartman

From: Takashi Iwai <[email protected]>

commit 64752a95b702817602d72f109ceaf5ec0780e283 upstream.

Recently we've added a new usb_mixer element type, USB_MIXER_BESPOKEN, but it wasn't added in the table in snd_usb_mixer_dump_cval(). This is no big problem since each bespoken type should have its own dump method, but it still isn't disallowed to use the standard one, so we should cover it as well. Along with it, define the table with the explicit array initializer for avoiding other pitfalls.

PATCH 74/108 ALSA: sb: Fix potential ABBA deadlock in CSP driver

In reply to Greg Kroah-Hartman

From: Takashi Iwai <[email protected]>

commit 1c2b9519159b470ef24b2638f4794e86e2952ab7 upstream.

SB16 CSP driver may hit potentially a typical ABBA deadlock in two code paths:

In snd_sb_csp_stop():

     spin_lock_irqsave(&p->chip->mixer_lock, flags);
     spin_lock(&p->chip->reg_lock);

In snd_sb_csp_load():

     spin_lock_irqsave(&p->chip->reg_lock, flags);
     spin_lock(&p->chip->mixer_lock);

Also the similar pattern is seen in snd_sb_csp_start().

Although the practical impact is very small (those states aren't triggered in the same running state and this happens only on a real hardware, decades old ISA sound boards -- which must be very difficult to find nowadays), it's a real scenario and has to be fixed.

This patch addresses those deadlocks by splitting the locks in snd_sb_csp_start() and snd_sb_csp_stop() for avoiding the nested locks.

PATCH 76/108 xhci: Fix lost USB 2 remote wake

In reply to Greg Kroah-Hartman

From: Mathias Nyman <[email protected]>

commit 72f68bf5c756f5ce1139b31daae2684501383ad5 upstream.

There's a small window where a USB 2 remote wake may be left unhandled due to a race between hub thread and xhci port event interrupt handler.

When the resume event is detected in the xhci interrupt handler it kicks the hub timer, which should move the port from resume to U0 once resume has been signalled for long enough.

To keep the hub "thread" running we set a bus_state->resuming_ports flag. This flag makes sure hub timer function kicks itself.

checking this flag was not properly protected by the spinlock. Flag was copied to a local variable before lock was taken. The local variable was then checked later with spinlock held.

If interrupt is handled right after copying the flag to the local variable we end up stopping the hub thread before it can handle the USB 2 resume.

CPU0 CPU1
(hub thread) (xhci event handler)

xhci_hub_status_data()

status = bus_state->resuming_ports;
					<Interrupt>
					handle_port_status()
					spin_lock()
					bus_state->resuming_ports = 1
					set_flag(HCD_FLAG_POLL_RH)
					spin_unlock()

spin_lock()
if (!status)
clear_flag(HCD_FLAG_POLL_RH)
spin_unlock()

Fix this by taking the lock a bit earlier so that it covers the resuming_ports flag copy in the hub thread

PATCH 77/108 KVM: PPC: Book3S: Fix H_RTAS rets buffer overflow

In reply to Greg Kroah-Hartman

From: Nicholas Piggin <[email protected]>

commit f62f3c20647ebd5fb6ecb8f0b477b9281c44c10a upstream.

The kvmppc_rtas_hcall() sets the host rtas_args.rets pointer based on the rtas_args.nargs that was provided by the guest. That guest nargs value is not range checked, so the guest can cause the host rets pointer to be pointed outside the args array. The individual rtas function handlers check the nargs and nrets values to ensure they are correct, but if they are not, the handlers store a -3 (0xfffffffd) failure indication in rets[0] which corrupts host memory.

Fix this by testing up front whether the guest supplied nargs and nret would exceed the array size, and fail the hcall directly without storing a failure indication to rets[0].

Also expand on a comment about why we kill the guest and try not to return errors directly if we have a valid rets[0] pointer.

PATCH 78/108 KVM: PPC: Book3S HV Nested: Sanitise H_ENTER_NESTED TM state

In reply to Greg Kroah-Hartman

From: Nicholas Piggin <[email protected]>

commit d9c57d3ed52a92536f5fa59dc5ccdd58b4875076 upstream.

The H_ENTER_NESTED hypercall is handled by the L0, and it is a request by the L1 to switch the context of the vCPU over to that of its L2 guest, and return with an interrupt indication. The L1 is responsible for switching some registers to guest context, and the L0 switches others (including all the hypervisor privileged state).

If the L2 MSR has TM active, then the L1 is responsible for recheckpointing the L2 TM state. Then the L1 exits to L0 via the H_ENTER_NESTED hcall, and the L0 saves the TM state as part of the exit, and then it recheckpoints the TM state as part of the nested entry and finally HRFIDs into the L2 with TM active MSR. Not efficient, but about the simplest approach for something that's horrendously complicated.

Problems arise if the L1 exits to the L0 with a TM state which does not match the L2 TM state being requested. For example if the L1 is transactional but the L2 MSR is non-transactional, or vice versa. The L0's HRFID can take a TM Bad Thing interrupt and crash.

Fix this by disallowing H_ENTER_NESTED in TM[T] state entirely, and then ensuring that if the L1 is suspended then the L2 must have TM active, and if the L1 is not suspended then the L2 must not have TM active.

PATCH 79/108 usb: hub: Disable USB 3 device initiated lpm if exit latency is too high

In reply to Greg Kroah-Hartman

From: Mathias Nyman <[email protected]>

commit 1b7f56fbc7a1b66967b6114d1b5f5a257c3abae6 upstream.

The device initiated link power management U1/U2 states should not be enabled in case the system exit latency plus one bus interval (125us) is greater than the shortest service interval of any periodic endpoint.

This is the case for both U1 and U2 sytstem exit latencies and link states.

See USB 3.2 section 9.4.9 "Set Feature" for more details

Note, before this patch the host and device initiated U1/U2 lpm states were both enabled with lpm. After this patch it's possible to end up with only host inititated U1/U2 lpm in case the exit latencies won't allow device initiated lpm.

If this case we still want to set the udev->usb3_lpm_ux_enabled flag so that sysfs users can see the link may go to U1/U2.

PATCH 80/108 usb: hub: Fix link power management max exit latency (MEL) calculations

In reply to Greg Kroah-Hartman

From: Mathias Nyman <[email protected]>

commit 1bf2761c837571a66ec290fb66c90413821ffda2 upstream.

Maximum Exit Latency (MEL) value is used by host to know how much in advance it needs to start waking up a U1/U2 suspended link in order to service a periodic transfer in time.

Current MEL calculation only includes the time to wake up the path from U1/U2 to U0. This is called tMEL1 in USB 3.1 section C 1.5.2

Total MEL = tMEL1 + tMEL2 +tMEL3 + tMEL4 which should additinally include:
- tMEL2 which is the time it takes for PING message to reach device
- tMEL3 time for device to process the PING and submit a PING_RESPONSE
- tMEL4 time for PING_RESPONSE to traverse back upstream to host.

Add the missing tMEL2, tMEL3 and tMEL4 to MEL calculation.

PATCH 82/108 usb: max-3421: Prevent corruption of freed memory

In reply to Greg Kroah-Hartman

From: Mark Tomlinson <[email protected]>

commit b5fdf5c6e6bee35837e160c00ac89327bdad031b upstream.

The MAX-3421 USB driver remembers the state of the USB toggles for a device/endpoint. To save SPI writes, this was only done when a new device/endpoint was being used. Unfortunately, if the old device was removed, this would cause writes to freed memory.

To fix this, a simpler scheme is used. The toggles are read from hardware when a URB is completed, and the toggles are always written to hardware when any URB transaction is started. This will cause a few more SPI transactions, but no causes kernel panics.

Fixes 2d53139f3162 ("Add support for using a MAX3421E chip as a host driver.")

PATCH 83/108 usb: renesas_usbhs: Fix superfluous irqs happen after usb_pkt_pop()

In reply to Greg Kroah-Hartman

From: Yoshihiro Shimoda <[email protected]>

commit 5719df243e118fb343725e8b2afb1637e1af1373 upstream.

This driver has a potential issue which this driver is possible to cause superfluous irqs after usb_pkt_pop() is called. So, after the commit 3af32605289e ("usb: renesas_usbhs: fix error return code of usbhsf_pkt_handler()") had been applied, we could observe the following error happened when we used g_audio.

    renesas_usbhs e6590000.usb: irq_ready run_error 1 : -22

To fix the issue, disable the tx or rx interrupt in usb_pkt_pop().

PATCH 88/108 firmware/efi: Tell memblock about EFI iomem reservations

In reply to Greg Kroah-Hartman

From: Marc Zyngier <[email protected]>

commit 2bab693a608bdf614b9fcd44083c5100f34b9f77 upstream.

kexec_load_file() relies on the memblock infrastructure to avoid stamping over regions of memory that are essential to the survival of the system.

However, nobody seems to agree how to flag these regions as reserved, and (for example) EFI only publishes its reservations in /proc/iomem for the benefit of the traditional, userspace based kexec tool.

On arm64 platforms with GICv3, this can result in the payload being placed at the location of the LPI tables. Shock, horror!

Let's augment the EFI reservation code with a memblock_reserve() call, protecting our dear tables from the secondary kernel invasion.

PATCH 89/108 tracing/histogram: Rename "cpu" to "common_cpu"

In reply to Greg Kroah-Hartman

From: Steven Rostedt (VMware) <[email protected]>

commit 1e3bac71c5053c99d438771fc9fa5082ae5d90aa upstream.

Currently the histogram logic allows the user to write "cpu" in as an event field, and it will record the CPU that the event happened on.

The problem with this is that there's a lot of events that have "cpu" as a real field, and using "cpu" as the CPU it ran on, makes it impossible to run histograms on the "cpu" field of events.

For example, if I want to have a histogram on the count of the workqueue_queue_work event on its cpu field, running:

Quoted 1 line
# echo 'hist:keys=cpu' > events/workqueue/workqueue_queue_work/trigger

Gives a misleading and wrong result.

Change the command to "common_cpu" as no event should have "common_*" fields as that's a reserved name for fields used by all events. And this makes sense here as common_cpu would be a field used by all events.

Now we can even do:

Quoted 2 lines
# echo 'hist:keys=common_cpu,cpu if cpu < 100' > events/workqueue/workqueue_queue_work/trigger
# cat events/workqueue/workqueue_queue_work/hist
 # event histogram
 #

 { common_cpu:          2, cpu:          2 } hitcount:        184

Now for backward compatibility, I added a trick. If "cpu" is used, and the field is not found, it will fall back to "common_cpu" and work as it did before. This way, it will still work for old programs that use "cpu" to get the actual CPU, but if the event has a "cpu" as a field, it will get that event's "cpu" field, which is probably what it wants anyway.

I updated the tracefs/README to include documentation about both the common_timestamp and the common_cpu. This way, if that text is present in the README, then an application can know that common_cpu is supported over just plain "cpu".

PATCH 90/108 tracing: Fix bug in rb_per_cpu_empty() that might cause deadloop.

In reply to Greg Kroah-Hartman

From: Haoran Luo <[email protected]>

commit 67f0d6d9883c13174669f88adac4f0ee656cc16a upstream.

The "rb_per_cpu_empty()" misinterpret the condition (as not-empty) when "head_page" and "commit_page" of "struct ring_buffer_per_cpu" points to the same buffer page, whose "buffer_data_page" is empty and "read" field is non-zero.

An error scenario could be constructed as followed (kernel perspective):

1. All pages in the buffer has been accessed by reader(s) so that all of them will have non-zero "read" field.

2. Read and clear all buffer pages so that "rb_num_of_entries()" will return 0 rendering there's no more data to read. It is also required that the "read_page", "commit_page" and "tail_page" points to the same page, while "head_page" is the next page of them.

3. Invoke "ring_buffer_lock_reserve()" with large enough "length" so that it shot pass the end of current tail buffer page. Now the "head_page", "commit_page" and "tail_page" points to the same page.

4. Discard current event with "ring_buffer_discard_commit()", so that "head_page", "commit_page" and "tail_page" points to a page whose buffer data page is now empty.

When the error scenario has been constructed, "tracing_read_pipe" will be trapped inside a deadloop: "trace_empty()" returns 0 since "rb_per_cpu_empty()" returns 0 when it hits the CPU containing such constructed ring buffer. Then "trace_find_next_entry_inc()" always return NULL since "rb_num_of_entries()" reports there's no more entry to read. Finally "trace_seq_to_user()" returns "-EBUSY" spanking "tracing_read_pipe" back to the start of the "waitagain" loop.

I've also written a proof-of-concept script to construct the scenario and trigger the bug automatically, you can use it to trace and validate my reasoning above:

https://github.com/aegistudio/RingBufferDetonator.git

Tests has been carried out on linux kernel 5.14-rc2 (2734d6c1b1a089fb593ef6a23d4b70903526fe0c), my fixed version of kernel (for testing whether my update fixes the bug) and some older kernels (for range of affected kernels). Test result is also attached to the proof-of-concept repository.

The reason is we call btrfs_trim_free_extents() for the missing device, which uses device->bdev (NULL for missing device) to find if the device supports discard.

Fix is to check if the device is missing before calling btrfs_trim_free_extents().

PATCH 92/108 media: ngene: Fix out-of-bounds bug in ngene_command_config_free_buf()

In reply to Greg Kroah-Hartman

From: Gustavo A. R. Silva <[email protected]>

commit 8d4abca95ecc82fc8c41912fa0085281f19cc29f upstream.

Fix an 11-year old bug in ngene_command_config_free_buf() while addressing the following warnings caught with -Warray-bounds:

arch/alpha/include/asm/string.h:22:16: warning: '__builtin_memcpy' offset [12, 16] from the object at 'com' is out of the bounds of referenced subobject 'config' with type 'unsigned char' at offset 10 [-Warray-bounds] arch/x86/include/asm/string_32.h:182:25: warning: '__builtin_memcpy' offset [12, 16] from the object at 'com' is out of the bounds of referenced subobject 'config' with type 'unsigned char' at offset 10 [-Warray-bounds]

The problem is that the original code is trying to copy 6 bytes of data into a one-byte size member _config_ of the wrong structue FW_CONFIGURE_BUFFERS, in a single call to memcpy(). This causes a legitimate compiler warning because memcpy() overruns the length of &com.cmd.ConfigureBuffers.config. It seems that the right structure is FW_CONFIGURE_FREE_BUFFERS, instead, because it contains 6 more members apart from the header _hdr_. Also, the name of the function ngene_command_config_free_buf() suggests that the actual intention is to ConfigureFreeBuffers, instead of ConfigureBuffers (which takes place in the function ngene_command_config_buf(), above).

Fix this by enclosing those 6 members of struct FW_CONFIGURE_FREE_BUFFERS into new struct config, and use &com.cmd.ConfigureFreeBuffers.config as the destination address, instead of &com.cmd.ConfigureBuffers.config, when calling memcpy().

This also helps with the ongoing efforts to globally enable -Warray-bounds and get us closer to being able to tighten the FORTIFY_SOURCE routines on memcpy().

PATCH 93/108 ixgbe: Fix packet corruption due to missing DMA sync

In reply to Greg Kroah-Hartman

From: Markus Boehme <[email protected]>

commit 09cfae9f13d51700b0fecf591dcd658fc5375428 upstream.

When receiving a packet with multiple fragments, hardware may still touch the first fragment until the entire packet has been received. The driver therefore keeps the first fragment mapped for DMA until end of packet has been asserted, and delays its dma_sync call until then.

The driver tries to fit multiple receive buffers on one page. When using 3K receive buffers (e.g. using Jumbo frames and legacy-rx is turned off/build_skb is being used) on an architecture with 4K pages, the driver allocates an order 1 compound page and uses one page per receive buffer. To determine the correct offset for a delayed DMA sync of the first fragment of a multi-fragment packet, the driver then cannot just use PAGE_MASK on the DMA address but has to construct a mask based on the actual size of the backing page.

Using PAGE_MASK in the 3K RX buffer/4K page architecture configuration will always sync the first page of a compound page. With the SWIOTLB enabled this can lead to corrupted packets (zeroed out first fragment, re-used garbage from another packet) and various consequences, such as slow/stalling data transfers and connection resets. For example, testing on a link with MTU exceeding 3058 bytes on a host with SWIOTLB enabled (e.g. "iommu=soft swiotlb=262144,force") TCP transfers quickly fizzle out without this patch.

PATCH 94/108 selftest: use mmap instead of posix_memalign to allocate memory

In reply to Greg Kroah-Hartman

From: Peter Collingbourne <[email protected]>

commit 0db282ba2c12c1515d490d14a1ff696643ab0f1b upstream.

This test passes pointers obtained from anon_allocate_area to the userfaultfd and mremap APIs. This causes a problem if the system allocator returns tagged pointers because with the tagged address ABI the kernel rejects tagged addresses passed to these APIs, which would end up causing the test to fail. To make this test compatible with such system allocators, stop using the system allocator to allocate memory in anon_allocate_area, and instead just use mmap.

PATCH 95/108 userfaultfd: do not untag user pointers

In reply to Greg Kroah-Hartman

From: Peter Collingbourne <[email protected]>

commit e71e2ace5721a8b921dca18b045069e7bb411277 upstream.

Patch series "userfaultfd: do not untag user pointers", v5.

If a user program uses userfaultfd on ranges of heap memory, it may end up passing a tagged pointer to the kernel in the range.start field of the UFFDIO_REGISTER ioctl. This can happen when using an MTE-capable allocator, or on Android if using the Tagged Pointers feature for MTE readiness [1].

When a fault subsequently occurs, the tag is stripped from the fault address returned to the application in the fault.address field of struct uffd_msg. However, from the application's perspective, the tagged address *is* the memory address, so if the application is unaware of memory tags, it may get confused by receiving an address that is, from its point of view, outside of the bounds of the allocation. We observed this behavior in the kselftest for userfaultfd [2] but other applications could have the same problem.

Address this by not untagging pointers passed to the userfaultfd ioctls. Instead, let the system call fail. Also change the kselftest to use mmap so that it doesn't encounter this problem.

[1] https://source.android.com/devices/tech/debug/tagged-pointers
[2] tools/testing/selftests/vm/userfaultfd.c

This patch (of 2):

Do not untag pointers passed to the userfaultfd ioctls. Instead, let the system call fail. This will provide an early indication of problems with tag-unaware userspace code instead of letting the code get confused later, and is consistent with how we decided to handle brk/mmap/mremap in commit dcde237319e6 ("mm: Avoid creating virtual address aliases in brk()/mmap()/mremap()"), as well as being consistent with the existing tagged address ABI documentation relating to how ioctl arguments are handled.

The code change is a revert of commit 7d0325749a6c ("userfaultfd: untag user pointers") plus some fixups to some additional calls to validate_range that have appeared since then.

PATCH 96/108 hugetlbfs: fix mount mode command line processing

In reply to Greg Kroah-Hartman

From: Mike Kravetz <[email protected]>

commit e0f7e2b2f7e7864238a4eea05cc77ae1be2bf784 upstream.

In commit 32021982a324 ("hugetlbfs: Convert to fs_context") processing of the mount mode string was changed from match_octal() to fsparam_u32.

This changed existing behavior as match_octal does not require octal values to have a '0' prefix, but fsparam_u32 does.

Use fsparam_u32oct which provides the same behavior as match_octal.

PATCH 97/108 rbd: dont hold lock_rwsem while running_list is being drained

In reply to Greg Kroah-Hartman

From: Ilya Dryomov <[email protected]>

commit ed9eb71085ecb7ded9a5118cec2ab70667cc7350 upstream.

Currently rbd_quiesce_lock() holds lock_rwsem for read while blocking on releasing_wait completion. On the I/O completion side, each image request also needs to take lock_rwsem for read. Because rw_semaphore implementation doesn't allow new readers after a writer has indicated interest in the lock, this can result in a deadlock if something that needs to take lock_rwsem for write gets involved. For example:

1. watch error occurs
2. rbd_watch_errcb() takes lock_rwsem for write, clears owner_cid and releases lock_rwsem
3. after reestablishing the watch, rbd_reregister_watch() takes lock_rwsem for write and calls rbd_reacquire_lock()
4. rbd_quiesce_lock() downgrades lock_rwsem to for read and blocks on releasing_wait until running_list becomes empty
5. another watch error occurs
6. rbd_watch_errcb() blocks trying to take lock_rwsem for write
7. no in-flight image request can complete and delete itself from running_list because lock_rwsem won't be granted anymore

A similar scenario can occur with "lock has been acquired" and "lock has been released" notification handers which also take lock_rwsem for write to update owner_cid.

We don't actually get anything useful from sitting on lock_rwsem in rbd_quiesce_lock() -- owner_cid updates certainly don't need to be synchronized with. In fact the whole owner_cid tracking logic could probably be removed from the kernel client because we don't support proxied maintenance operations.

PATCH 98/108 rbd: always kick acquire on "acquired" and "released" notifications

In reply to Greg Kroah-Hartman

From: Ilya Dryomov <[email protected]>

commit 8798d070d416d18a75770fc19787e96705073f43 upstream.

Skipping the "lock has been released" notification if the lock owner is not what we expect based on owner_cid can lead to I/O hangs. One example is our own notifications: because owner_cid is cleared in rbd_unlock(), when we get our own notification it is processed as unexpected/duplicate and maybe_kick_acquire() isn't called. If a peer that requested the lock then doesn't go through with acquiring it, I/O requests that came in while the lock was being quiesced would be stalled until another I/O request is submitted and kicks acquire from rbd_img_exclusive_lock().

This makes the comment in rbd_release_lock() actually true: prior to this change the canceled work was being requeued in response to the "lock has been acquired" notification from rbd_handle_acquired_lock().

commit c453db6cd96418c79702eaf38259002755ab23ff upstream.

Commit 1be7107fbe18 ("mm: larger stack guard gap, between vmas") fixed up all architectures to deal with the stack guard gap. But when nds32 was added to the tree, it forgot to do the same thing.

Resolve this by properly fixing up the nsd32's version of arch_get_unmapped_area()

PATCH 100/108 drm: Return -ENOTTY for non-drm ioctls

In reply to Greg Kroah-Hartman

From: Charles Baylis <[email protected]>

commit 3abab27c322e0f2acf981595aa8040c9164dc9fb upstream.

drm: Return -ENOTTY for non-drm ioctls

Return -ENOTTY from drm_ioctl() when userspace passes in a cmd number which doesn't relate to the drm subsystem.

Glibc uses the TCGETS ioctl to implement isatty(), and without this change isatty() returns it incorrectly returns true for drm devices.

To test run this command:

$ if [ -t 0 ]; then echo is a tty; fi < /dev/dri/card0
which shows "is a tty" without this patch.

This may also modify memory which the userspace application is not expecting.

PATCH 102/108 net: bcmgenet: ensure EXT_ENERGY_DET_MASK is clear

In reply to Greg Kroah-Hartman

From: Doug Berger <[email protected]>

commit 5a3c680aa2c12c90c44af383fe6882a39875ab81 upstream.

Setting the EXT_ENERGY_DET_MASK bit allows the port energy detection logic of the internal PHY to prevent the system from sleeping. Some internal PHYs will report that energy is detected when the network interface is closed which can prevent the system from going to sleep if WoL is enabled when the interface is brought down.

Since the driver does not support waking the system on this logic, this commit clears the bit whenever the internal PHY is powered up and the other logic for manipulating the bit is removed since it serves no useful function.

Fixes 1c1008c793fa ("net: bcmgenet: add main driver file")

PATCH 104/108 iio: accel: bma180: Fix BMA25x bandwidth register values

In reply to Greg Kroah-Hartman

From: Stephan Gerhold <[email protected]>

commit 8090d67421ddab0ae932abab5a60200598bf0bbb upstream

According to the BMA253 datasheet [1] and BMA250 datasheet [2] the bandwidth value for BMA25x should be set as 01xxx:

"Settings 00xxx result in a bandwidth of 7.81 Hz; [...]
It is recommended [...] to use the range from ´01000b´ to ´01111b´ only in order to be compatible with future products."

However, at the moment the drivers sets bandwidth values from 0 to 6, which is not recommended and always results into 7.81 Hz bandwidth according to the datasheet.

Fix this by introducing a bw_offset = 8 = 01000b for BMA25x, so the additional bit is always set for BMA25x.

PATCH 105/108 btrfs: compression: dont try to compress if we dont have enough pages

In reply to Greg Kroah-Hartman

From: David Sterba <[email protected]>

commit f2165627319ffd33a6217275e5690b1ab5c45763 upstream

The early check if we should attempt compression does not take into account the number of input pages. It can happen that there's only one page, eg. a tail page after some ranges of the BTRFS_MAX_UNCOMPRESSED have been processed, or an isolated page that won't be converted to an inline extent.

The single page would be compressed but a later check would drop it again because the result size must be at least one block shorter than the input. That can never work with just one page.

PATCH 106/108 PCI: Mark AMD Navi14 GPU ATS as broken

In reply to Greg Kroah-Hartman

From: Evan Quan <[email protected]>

commit e8946a53e2a698c148b3b3ed732f43c7747fbeb6 upstream

Observed unexpected GPU hang during runpm stress test on 0x7341 rev 0x00. Further debugging shows broken ATS is related.

Disable ATS on this part. Similar issues on other devices:

PATCH 107/108 perf inject: Close inject.output on exit

In reply to Greg Kroah-Hartman

From: Riccardo Mancini <[email protected]>

commit 02e6246f5364d5260a6ea6f92ab6f409058b162f upstream.

ASan reports a memory leak when running:

  # perf test "83: Zstd perf.data compression/decompression"

which happens inside 'perf inject'.

The bug is caused by inject.output never being closed.

This patch adds the missing perf_data__close().

Fixes 6ef81c55a2b6584c ("perf session: Return error code for perf_session__new() function on failure")

PATCH 108/108 xhci: add xhci_get_virt_ep() helper

In reply to Greg Kroah-Hartman

From: Mathias Nyman <[email protected]>

[commit b1adc42d440df3233255e313a45ab7e9b2b74096 upstream]

In several event handlers we need to find the right endpoint structure from slot_id and ep_index in the event.

Add a helper for this, check that slot_id and ep_index are valid.
