commit 32108c22ac619c32dd6db594319e259b63bfb387 upstream.

UMP events don't use the event type field, hence it's invalid to apply the filter, which may drop the events unexpectedly. Skip the event filtering for UMP events, instead.

commit 2dc43c5e212036458ed7c5586fb82ee183fee504 upstream.

This patch adds the HP Pavilion Aero 13 (13-bg0xxx) (year 2024) to list of quirks for keyboard LED mute indication.

The laptop has two LEDs (one for speaker and one for mic mute). The pre-existing quirk ALC245_FIXUP_HP_X360_MUTE_LEDS chains both the quirk for mic and speaker mute.

Tested on 6.11.0-rc4 with the aforementioned laptop.

commit 80376323e2b6a4559f86b2b4d864848ac25cb054 upstream.

There exist some warnings when building kernel if CONFIG_CPU_HAS_LBT is set but CONFIG_CPU_HAS_LSX and CONFIG_CPU_HAS_LASX are not set. In this case, there are no definitions of _restore_lsx & _restore_lasx and there are also no definitions of kvm_restore_lsx & kvm_restore_lasx in fpu.S and switch.S respectively, just add some ifdefs to fix these warnings.

[CAUSE] Although I cannot reproduce the error, the report itself is good enough to pin down the cause.

The call trace is the regular endio workqueue context, but the free-by-task trace is showing that during btrfs_submit_chunk() we already hit a critical error, and is calling btrfs_bio_end_io() to error out. And the original endio function called bio_put() to free the whole bio.

This means a double freeing thus causing use-after-free, e.g.:

1. Enter btrfs_submit_bio() with a read bio The read bio length is 128K, crossing two 64K stripes.

2. The first run of btrfs_submit_chunk()

2.1 Call btrfs_map_block(), which returns 64K 2.2 Call btrfs_split_bio() Now there are two bios, one referring to the first 64K, the other referring to the second 64K. 2.3 The first half is submitted.

3. The second run of btrfs_submit_chunk()

3.1 Call btrfs_map_block(), which by somehow failed Now we call btrfs_bio_end_io() to handle the error

3.2 btrfs_bio_end_io() calls the original endio function Which is end_bbio_data_read(), and it calls bio_put() for the original bio.

Now the original bio is freed.

4. The submitted first 64K bio finished Now we call into btrfs_check_read_bio() and tries to advance the bio iter. But since the original bio (thus its iter) is already freed, we trigger the above use-after free.

And even if the memory is not poisoned/corrupted, we will later call the original endio function, causing a double freeing.

[FIX] Instead of calling btrfs_bio_end_io(), call btrfs_orig_bbio_end_io(), which has the extra check on split bios and do the proper refcounting for cloned bios.

Furthermore there is already one extra btrfs_cleanup_bio() call, but that is duplicated to btrfs_orig_bbio_end_io() call, so remove that label completely.

commit 8af174ea863c72f25ce31cee3baad8a301c0cf0f upstream.

The mana_hwc_rx_event_handler() / mana_hwc_handle_resp() calls complete(&ctx->comp_event) before posting the wqe back. It's possible that other callers, like mana_create_txq(), start the next round of mana_hwc_send_request() before the posting of wqe. And if the HW is fast enough to respond, it can hit no_wqe error on the HW channel, then the response message is lost. The mana driver may fail to create queues and open, because of waiting for the HW response and timed out. Sample dmesg: [ 528.610840] mana 39d4:00:02.0: HWC: Request timed out! [ 528.614452] mana 39d4:00:02.0: Failed to send mana message: -110, 0x0 [ 528.618326] mana 39d4:00:02.0 enP14804s2: Failed to create WQ object: -110

To fix it, move posting of rx wqe before complete(&ctx->comp_event).

commit 2a1f596ebb23eadc0f9b95a8012e18ef76295fc8 upstream.

The 'mptcp_subflow_context' structure has two items related to the backup flags:

- 'backup': the subflow has been marked as backup by the other peer

- 'request_bkup': the backup flag has been set by the host

Looking only at the 'backup' flag can make sense in some cases, but it is not the behaviour of the default packet scheduler when selecting paths.

As explained in the commit b6a66e521a20 ("mptcp: sched: check both directions for backup"), the packet scheduler should look at both flags, because that was the behaviour from the beginning: the 'backup' flag was set by accident instead of the 'request_bkup' one. Now that the latter has been fixed, get_retrans() needs to be adapted as well.

When the endpoint used by the initial subflow is removed and re-added later, the PM has to force the ID 0, it is a special case imposed by the MPTCP specs.

Note that the endpoint should then need to be re-added reusing the same ID.

commit dce1c6d1e92535f165219695a826caedcca4e9b9 upstream.

The initial subflow has a special local ID: 0. It is specific per connection.

When a global endpoint is deleted and re-added later, it can have a different ID -- most services managing the endpoints automatically don't force the ID to be the same as before. It is then important to track these modifications to be consistent with the ID being used for the address used by the initial subflow, not to confuse the other peer or to send the ID 0 for the wrong address.

Now when removing an endpoint, msk->mpc_endpoint_id is reset if it corresponds to this endpoint. When adding a new endpoint, the same variable is updated if the address match the one of the initial subflow.

commit 87b5896f3f7848130095656739b05881904e2697 upstream.

The initial subflow has a special local ID: 0. When an endpoint is being deleted, it is then important to check if its address is not linked to the initial subflow to send the right ID.

If there was an endpoint linked to the initial subflow, msk's mpc_endpoint_id field will be set. We can then use this info when an endpoint is being removed to see if it is linked to the initial subflow.

So now, the correct IDs are passed to mptcp_pm_nl_rm_addr_or_subflow(), it is no longer needed to use mptcp_local_id_match().

commit 9366922adc6a71378ca01f898c41be295309f044 upstream.

'local_addr_used' and 'add_addr_accepted' are decremented for addresses not related to the initial subflow (ID0), because the source and destination addresses of the initial subflows are known from the beginning: they don't count as "additional local address being used" or "ADD_ADDR being accepted".

It is then required not to increment them when the entrypoint used by the initial subflow is removed and re-added during a connection. Without this modification, this entrypoint cannot be removed and re-added more than once.

From: Matthieu Baerts (NGI0) matttbe@kernel.org

commit 57f86203b41c98b322119dfdbb1ec54ce5e3369b upstream.

The ADD_ADDR 0 with the address from the initial subflow should not be considered as a new address: this is not something new. If the host receives it, it simply means that the address is available again.

When receiving an ADD_ADDR for the ID 0, the PM already doesn't consider it as new by not incrementing the 'add_addr_accepted' counter. But the 'accept_addr' might not be set if the limit has already been reached: this can be bypassed in this case. But before, it is important to check that this ADD_ADDR for the ID 0 is for the same address as the initial subflow. If not, it is not something that should happen, and the ADD_ADDR can be ignored.

Note that if an ADD_ADDR is received while there is already a subflow opened using the same address, this ADD_ADDR is ignored as well. It means that if multiple ADD_ADDR for ID 0 are received, there will not be any duplicated subflows created by the client.

commit 5f94b08c001290acda94d9d8868075590931c198 upstream.

Removing the endpoint linked to the initial subflow should trigger a RM_ADDR for the right ID, and the removal of the subflow. That's what is now being verified in the "delete and re-add" test.

Note that removing the initial subflow will not decrement the 'subflows' counters, which corresponds to the *additional* subflows. On the other hand, when the same endpoint is re-added, it will increment this counter, as it will be seen as an additional subflow this time.

The 'Fixes' tag here below is the same as the one from the previous commit: this patch here is not fixing anything wrong in the selftests, but it validates the previous fix for an issue introduced by this commit ID.

commit d397d7246c11ca36c33c932bc36d38e3a79e9aa0 upstream.

This test extends "delete and re-add" to validate the previous commit: when the endpoint linked to the initial subflow (ID 0) is re-added multiple times, it was no longer being used, because the internal linked counters are not decremented for this special endpoint: it is not an additional endpoint.

Here, the "del/add id 0" steps are done 3 times to unsure this case is validated.

The 'Fixes' tag here below is the same as the one from the previous commit: this patch here is not fixing anything wrong in the selftests, but it validates the previous fix for an issue introduced by this commit ID.

From: Imre Deak imre.deak@intel.com

commit a2ccc33b88e2953a6bf0b309e7e8849cc5320018 upstream.

In some cases the sink can reset itself after it was configured into MST mode, without the driver noticing the disconnected state. For instance the reset may happen in the middle of a modeset, or the (long) HPD pulse generated may be not long enough for the encoder detect handler to observe the HPD's deasserted state. In this case the sink's DPCD register programmed to enable MST will be reset, while the driver still assumes MST is still enabled. Detect this condition, which will tear down and recreate/re-enable the MST topology.

v2: - Add a code comment about adjusting the expected DP_MSTM_CTRL register value for SST + SideBand. (Suraj, Jani) - Print a debug message about detecting the link reset. (Jani) - Verify the DPCD MST state only if it wasn't already determined that the sink is disconnected.

commit d420c857d85777663e8d16adfc24463f5d5c2dbc upstream.

Always reprogram the hardware state on init. This ensures the PMFW state is explicitly programmed and we are not relying on the default PMFW state.

commit 50f1199250912568606b3778dc56646c10cb7b04 upstream.

Make sure that for external buffers mapping goes through the dma_buf interface instead of trying to access pages directly.

External buffers might not provide direct access to readable/writable pages so to make sure the bo's created from external dma_bufs can be read dma_buf interface has to be used.

Fixes crashes in IGT's kms_prime with vgem. Regular desktop usage won't trigger this due to the fact that virtual machines will not have multiple GPUs but it enables better test coverage in IGT.

In aperture_remove_conflicting_pci_devices(), we currently only call sysfb_disable() on vga class devices. This leads to the following problem when the pimary device is not VGA compatible:

1. A PCI device with a non-VGA class is the boot display 2. That device is probed first and it is not a VGA device so sysfb_disable() is not called, but the device resources are freed by aperture_detach_platform_device() 3. Non-primary GPU has a VGA class and it ends up calling sysfb_disable() 4. NULL pointer dereference via sysfb_disable() since the resources have already been freed by aperture_detach_platform_device() when it was called by the other device.

Fix this by passing a device pointer to sysfb_disable() and checking the device to determine if we should execute it or not.

v2: Fix build when CONFIG_SCREEN_INFO is not set v3: Move device check into the mutex Drop primary variable in aperture_remove_conflicting_pci_devices() Drop __init on pci sysfb_pci_dev_is_enabled()

[ Upstream commit ddf6492e0e508b7c2b42c8d5a4ac82bd38ef0dd5 ]

We should unpin before evicting all memory, and repin after GT resume. This way, we preserve the contents of the framebuffers, and won't hang on resume due to migration engine not being restored yet.

The current map seems to be out of sync (and includes a duplicate entry for GPIO193..).

Replace it with the map present in shipping devices' ACPI tables.

This new one seems more complete, as it e.g. contains GPIO145 (PCIE6a WAKE#)

[ Upstream commit 897e91e995b338002b00454fd0018af26a098148 ]

Addition of 'dsp_intr_base' to ACP error register offsets points to wrong register offsets in irq handler. Correct the acp error register offsets. ACP error status register offset and acp error reason register offset got changed from ACP6.0 onwards. Add 'acp_error_stat' and 'acp_sw0_i2s_err_reason' as descriptor fields in sof_amd_acp_desc structure and update the values based on the ACP variant.

From Rembrandt platform onwards, errors related to SW1 Soundwire manager

instance/I2S controller connected on P1 power tile is reported with ACP_SW1_I2S_ERROR_REASON register. Add conditional check for the same.

[ Upstream commit a42db293e5983aa1508d12644f23d73f0553b32c ]

When ACP is not powered on by default, acp power on sequence explicitly invoked by programming pgfsm control mask. The existing implementation checks the same PGFSM status mask and programs the same PGFSM control mask in all ACP variants which breaks acp power on sequence for ACP6.0 and ACP6.3 variants. So to fix this issue, update ACP pgfsm control mask and status mask based on acp descriptor rev field, which will vary based on acp variant.

[ Upstream commit 166bf8af91225576f85208a31eaedbadd182d1ea ]

Despite its name, commit fed74d75277d ("pinctrl: mediatek: common-v2: Fix bias-disable for PULL_PU_PD_RSEL_TYPE") actually broke bias-disable for PULL_PU_PD_RSEL_TYPE.

mtk_pinconf_bias_set_combo() tries every bias method supported by the pin until one succeeds. For PULL_PU_PD_RSEL_TYPE pins, before the breaking commit, mtk_pinconf_bias_set_rsel() would be called first to try and set the RSEL value (as well as PU and PD), and if that failed, the only other valid option was that bias-disable was specified, which would then be handled by calling mtk_pinconf_bias_set_pu_pd() and disabling both PU and PD.

The breaking commit misunderstood this logic and added an early "return 0" in mtk_pinconf_bias_set_rsel(). The result was that in the bias-disable case, the bias was left unchanged, since by returning success, mtk_pinconf_bias_set_combo() no longer tried calling mtk_pinconf_bias_set_pu_pd() to disable the bias.

Since the logic for configuring bias-disable on PULL_PU_PD_RSEL_TYPE pins required mtk_pinconf_bias_set_rsel() to fail first, in that case, an error was printed to the log, eg:

mt8195-pinctrl 10005000.pinctrl: Not support rsel value 0 Ohm for pin = 29 (GPIO29)

This is what the breaking commit actually got rid of, and likely part of the reason why that commit was thought to be fixing functionality, while in reality it was breaking it.

Instead of simply reverting that commit, restore the functionality but in a way that avoids the error from being printed and makes the code less confusing: * Return 0 explicitly if a bias method was successful * Introduce an extra function mtk_pinconf_bias_set_pu_pd_rsel() that calls both mtk_pinconf_bias_set_rsel() (only if needed) and mtk_pinconf_bias_set_pu_pd() * And analogously for the corresponding getters

[ Upstream commit 0aa2e1b2fb7a75aa4b5b4347055ccfea6f091769 ]

When AS_RELEASE_ALWAYS is set on a mapping, the ->release_folio() and ->invalidate_folio() calls should be invoked even if PG_private and PG_private_2 aren't set. This is used by netfslib to keep track of the point above which reads can be skipped in favour of just zeroing pagecache locally.

There are a couple of places in truncation in which invalidation is only called when folio_has_private() is true. Fix these to check folio_needs_release() instead.

Without this, the generic/075 and generic/112 xfstests (both fsx-based tests) fail with minimum folio size patches applied[1].

Fix netfs_release_folio() to say no (ie. return false) if the folio is dirty (analogous with iomap's behaviour). Without this, it will say yes to the release of a dirty page by split_huge_page_to_list_to_order(), which will result in the loss of untruncated data in the folio.

Without this, the generic/075 and generic/112 xfstests (both fsx-based tests) fail with minimum folio size patches applied[1].

Currently, we copy the mtime and ctime to the in-core inode and then mark the inode dirty. This is fine for certain types of filesystems, but not all. Some require a real setattr to properly change these values (e.g. ceph or reexported NFS).

Fix this code to call notify_change() instead, which is the proper way to effect a setattr. There is one problem though:

In this case, the client is holding a write delegation and has sent us attributes to update our cache. We don't want to break the delegation for this since that would defeat the purpose. Add a new ATTR_DELEG flag that makes notify_change bypass the try_break_deleg call.

commit 0d8584d288a9b4132e945d76bcc04395d158b2e7 upstream.

After the commit 63edbaa48a57 ("x86/cpu/topology: Add support for the AMD 0x80000026 leaf"), the topolgy_logical_die_id() function returns the logical Core Chiplet Die (CCD) ID instead of the logical socket ID.

Since this is currently used to set MSR_AMD_CPPC_ENABLE, which needs to be set on any one of the threads of the socket, it is prudent to use topology_logical_package_id() in place of topology_logical_die_id().

commit 383baf5c8f062091af34c63f28d37642a8f188ae upstream.

The current logic is enabling both STOP_INT_MASK and ABORT_INT_MASK bit. This is apparently masking those particular interrupts rather than unmasking the same. If the interrupts are masked, they would never get triggered.

So fix the issue by unmasking the STOP and ABORT interrupts properly.

[ Upstream commit b336268dde75cb09bd795cb24893d52152a9191f ]

Currently the src_addr_width and dst_addr_width fields of the dma_slave_config structure are mapped to the CTLx.SRC_TR_WIDTH and CTLx.DST_TR_WIDTH fields of the peripheral bus side in order to have the properly aligned data passed to the target device. It's done just by converting the passed peripheral bus width to the encoded value using the __ffs() function. This implementation has several problematic sides:

1. __ffs() is undefined if no bit exist in the passed value. Thus if the specified addr-width is DMA_SLAVE_BUSWIDTH_UNDEFINED, __ffs() may return unexpected value depending on the platform-specific implementation.

2. DW AHB DMA-engine permits having the power-of-2 transfer width limited by the DMAH_Mk_HDATA_WIDTH IP-core synthesize parameter. Specifying bus-width out of that constraints scope will definitely cause unexpected result since the destination reg will be only partly touched than the client driver implied.

Let's fix all of that by adding the peripheral bus width verification method and calling it in dwc_config() which is supposed to be executed before preparing any transfer. The new method will make sure that the passed source or destination address width is valid and if undefined then the driver will just fallback to the 1-byte width transfer.

If a system is using preferred cores the highest perf will be inconsistent as it can change from system events.

Skip the checks for it.

[ Upstream commit 35237475384ab3622f63c3c09bdf6af6dacfe9c3 ]

This fixes the random kernel crash seen while removing the driver, when running the load/unload test over multiple iterations.

1) modprobe btnxpuart 2) hciconfig hci0 reset 3) hciconfig (check hci0 interface up with valid BD address) 4) modprobe -r btnxpuart Repeat steps 1 to 4

The ps_wakeup() call in btnxpuart_close() schedules the psdata->work(), which gets scheduled after module is removed, causing a kernel crash.

This hidden issue got highlighted after enabling Power Save by default in 4183a7be7700 (Bluetooth: btnxpuart: Enable Power Save feature on startup)

The new ps_cleanup() deasserts UART break immediately while closing serdev device, cancels any scheduled ps_work and destroys the ps_lock mutex.

[ Upstream commit 6093cd582f8e027117a8d4ad5d129a1aacdc53d2 ]

These three implementations of map_pages() all succeed if a mapping is requested with no read or write. Since they return back to __iommu_map() leaving the mapped output as 0 it triggers an infinite loop. Therefore nothing is using no-access protection bits.

Further, VFIO and iommufd rely on iommu_iova_to_phys() to get back PFNs stored by map, if iommu_map() succeeds but iommu_iova_to_phys() fails that will create serious bugs.

Thus remove this never used "nothing to do" concept and just fail map immediately.

When sockfd_lookup() fails, gtp_encap_enable_socket() returns a NULL pointer, but its callers only check for error pointers thus miss the NULL pointer case.

Fix it by returning an error pointer with the error code carried from sockfd_lookup().

[ Upstream commit 3a0504d54b3b57f0d7bf3d9184a00c9f8887f6d7 ]

sctp_sf_do_5_2_4_dupcook() currently calls security_sctp_assoc_request() on new_asoc, but as it turns out, this association is always discarded and the LSM labels never get into the final association (asoc).

This can be reproduced by having two SCTP endpoints try to initiate an association with each other at approximately the same time and then peel off the association into a new socket, which exposes the unitialized labels and triggers SELinux denials.

Fix it by calling security_sctp_assoc_request() on asoc instead of new_asoc. Xin Long also suggested limit calling the hook only to cases A, B, and D, since in cases C and E the COOKIE ECHO chunk is discarded and the association doesn't enter the ESTABLISHED state, so rectify that as well.

One related caveat with SELinux and peer labeling: When an SCTP connection is set up simultaneously in this way, we will end up with an association that is initialized with security_sctp_assoc_request() on both sides, so the MLS component of the security context of the association will get swapped between the peers, instead of just one side setting it to the other's MLS component. However, at that point security_sctp_assoc_request() had already been called on both sides in sctp_sf_do_unexpected_init() (on a temporary association) and thus if the exchange didn't fail before due to MLS, it won't fail now either (most likely both endpoints have the same MLS range).

Tested by: - reproducer from https://src.fedoraproject.org/tests/selinux/pull-request/530 - selinux-testsuite (https://github.com/SELinuxProject/selinux-testsuite/) - sctp-tests (https://github.com/sctp/sctp-tests) - no tests failed that wouldn't fail also without the patch applied

Typically, busy-polling durations are below 100 usec.

When/if the busy-poller thread migrates to another cpu, local_clock() can be off by +/-2msec or more for small values of HZ, depending on the platform.

Use ktimer_get_ns() to ensure deterministic behavior, which is the whole point of busy-polling.

commit f9bb896eab221618927ae6a2f1d566567999839d upstream.

Linux does not write into cmd-db region. This region of memory is write protected by XPU. XPU may sometime falsely detect clean cache eviction as "write" into the write protected region leading to secure interrupt which causes an endless loop somewhere in Trust Zone.

The only reason it is working right now is because Qualcomm Hypervisor maps the same region as Non-Cacheable memory in Stage 2 translation tables. The issue manifests if we want to use another hypervisor (like Xen or KVM), which does not know anything about those specific mappings.

Changing the mapping of cmd-db memory from MEMREMAP_WB to MEMREMAP_WT/WC removes dependency on correct mappings in Stage 2 tables. This patch fixes the issue by updating the mapping to MEMREMAP_WC.

I tested this on SA8155P with Xen.

commit 3568affcddd68743e25aa3ec1647d9b82797757b upstream.

As pointed out by Stephen Boyd it is possible that during initialization of the pmic_glink child drivers, the protection-domain notifiers fires, and the associated work is scheduled, before the client registration returns and as a result the local "client" pointer has been initialized.

The outcome of this is a NULL pointer dereference as the "client" pointer is blindly dereferenced.

Timeline provided by Stephen: CPU0 CPU1 ---- ---- ucsi->client = NULL; devm_pmic_glink_register_client() client->pdr_notify(client->priv, pg->client_state) pmic_glink_ucsi_pdr_notify() schedule_work(&ucsi->register_work) <schedule away> pmic_glink_ucsi_register() ucsi_register() pmic_glink_ucsi_read_version() pmic_glink_ucsi_read() pmic_glink_ucsi_read() pmic_glink_send(ucsi->client) <client is NULL BAD> ucsi->client = client // Too late!

This code is identical across the altmode, battery manager and usci child drivers.

Resolve this by splitting the allocation of the "client" object and the registration thereof into two operations.

This only happens if the protection domain registry is populated at the time of registration, which by the introduction of commit '1ebcde047c54 ("soc: qcom: add pd-mapper implementation")' became much more likely.

Some FSA4480-compatible chips like the OCP96011 used on Fairphone 5 return 0x00 from the CHIP_ID register. Handle that gracefully and only fail probe when the I2C read has failed.

With this the dev_dbg will print 0 but otherwise continue working.

commit 4f9eedfa27ae5806ed10906bcceee7bae49c8941 upstream.

If formatting a suspended disk (such as formatting with different DIF type), the disk will be resuming first, and then the format command will submit to the disk through SG_IO ioctl.

When the disk is processing the format command, the system does not submit other commands to the disk. Therefore, the system attempts to suspend the disk again and sends the SYNCHRONIZE CACHE command. However, the SYNCHRONIZE CACHE command will fail because the disk is in the formatting process. This will cause the runtime_status of the disk to error and it is difficult for user to recover it. Error info like:

[ 669.925325] sd 6:0:6:0: [sdg] Synchronizing SCSI cache [ 670.202371] sd 6:0:6:0: [sdg] Synchronize Cache(10) failed: Result: hostbyte=0x00 driverbyte=DRIVER_OK [ 670.216300] sd 6:0:6:0: [sdg] Sense Key : 0x2 [current] [ 670.221860] sd 6:0:6:0: [sdg] ASC=0x4 ASCQ=0x4

To solve the issue, ignore the error and return success/0 when format is in progress.

commit 8512fbb64b0e599412da661412d10d4ba1cb003c upstream.

On the imx6dl-yapp4 revision based boards, the RGB LED is not driven directly by the LP5562 driver but through FET transistors. Hence the LED current is not determined by the driver but by the LED series resistors.

On the imx6dl-yapp43 revision based boards, we removed the FET transistors to drive the LED directly from the LP5562 but forgot to tune the output current to match the previous HW design.

Set the LED current on imx6dl-yapp43 based boards to the same values measured on the imx6dl-yapp4 boards and limit the maximum current to 20mA.

From: Selvarasu Ganesan selvarasu.g@samsung.com

commit 14e497183df28c006603cc67fd3797a537eef7b9 upstream.

This commit addresses an issue where the USB core could access an invalid event buffer address during runtime suspend, potentially causing SMMU faults and other memory issues in Exynos platforms. The problem arises from the following sequence. 1. In dwc3_gadget_suspend, there is a chance of a timeout when moving the USB core to the halt state after clearing the run/stop bit by software. 2. In dwc3_core_exit, the event buffer is cleared regardless of the USB core's status, which may lead to an SMMU faults and other memory issues. if the USB core tries to access the event buffer address.

To prevent this hardware quirk on Exynos platforms, this commit ensures that the event buffer address is not cleared by software when the USB core is active during runtime suspend by checking its status before clearing the buffer address.

commit 11bb2ffb679399f99041540cf662409905179e3a upstream.

Commit '9329933699b3 ("soc: qcom: pmic_glink: Make client-lock non-sleeping")' moved the pmic_glink client list under a spinlock, as it is accessed by the rpmsg/glink callback, which in turn is invoked from IRQ context.

This means that ucsi_unregister() is now called from atomic context, which isn't feasible as it's expecting a sleepable context. An effort is under way to get GLINK to invoke its callbacks in a sleepable context, but until then lets schedule the unregistration.

A side effect of this is that ucsi_unregister() can now happen after the remote processor, and thereby the communication link with it, is gone. pmic_glink_send() is amended with a check to avoid the resulting NULL pointer dereference. This does however result in the user being informed about this error by the following entry in the kernel log:

ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: failed to send UCSI write request: -5

[ Upstream commit 919ddf8336f0b84c0453bac583808c9f165a85c2 ]

aac_probe_one() calls hardware-specific init functions through the aac_driver_ident::init pointer, all of which eventually call down to aac_init_adapter().

If aac_init_adapter() fails after allocating memory for aac_dev::queues, it frees the memory but does not clear that member.

After the hardware-specific init function returns an error, aac_probe_one() goes down an error path that frees the memory pointed to by aac_dev::queues, resulting.in a double-free.

[ Upstream commit 40927f3d0972bf86357a32a5749be71a551241b6 ]

It is not safe to dereference fl->c.flc_owner without first confirming fl->fl_lmops is the expected manager. nfsd4_deleg_getattr_conflict() tests fl_lmops but largely ignores the result and assumes that flc_owner is an nfs4_delegation anyway. This is wrong.

With this patch we restore the "!= &nfsd_lease_mng_ops" case to behave as it did before the change mentioned below. This is the same as the current code, but without any reference to a possible delegation.
