2024-09-06netpoll: remove netpoll_srcuEric Dumazet
netpoll_srcu is currently used from netpoll_poll_disable() and __netpoll_cleanup() Both functions run under RTNL, using netpoll_srcu adds confusion and no additional protection. Moreover the synchronize_srcu() call in __netpoll_cleanup() is performed before clearing np->dev->npinfo, which violates RCU rules. After this patch, netpoll_poll_disable() and netpoll_poll_enable() simply use rtnl_dereference(). This saves a big chunk of memory (more than 192KB on platforms with 512 cpus) Signed-off-by: Eric Dumazet <edumazet@google.com> Reviewed-by: Breno Leitao <leitao@debian.org> Link: https://patch.msgid.link/20240905084909.2082486-1-edumazet@google.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2024-09-06octeontx2-af: Pass string literal as format argument of alloc_workqueue()Simon Horman
Recently I noticed that both gcc-14 and clang-18 report that passing a non-string literal as the format argument of alloc_workqueue() is potentially insecure. E.g. clang-18 says: .../rvu.c:2493:32: warning: format string is not a string literal (potentially insecure) [-Wformat-security] 2493 | mw->mbox_wq = alloc_workqueue(name, | ^~~~ .../rvu.c:2493:32: note: treat the string as an argument to avoid this 2493 | mw->mbox_wq = alloc_workqueue(name, | ^ | "%s", It is always the case where the contents of name is safe to pass as the format argument. That is, in my understanding, it never contains any format escape sequences. But, it seems better to be safe than sorry. And, as a bonus, compiler output becomes less verbose by addressing this issue as suggested by clang-18. Compile tested only by author.

2024-09-06net: tls: wait for async completion on last messageSascha Hauer
When asynchronous encryption is used KTLS sends out the final data at proto->close time. This becomes problematic when the task calling close() receives a signal. In this case it can happen that tcp_sendmsg_locked() called at close time returns -ERESTARTSYS and the final data is not sent. The described situation happens when KTLS is used in conjunction with io_uring, as io_uring uses task_work_add() to add work to the current userspace task. A discussion of the problem along with a reproducer can be found in [1] and [2] Fix this by waiting for the asynchronous encryption to be completed on the final message. With this there is no data left to be sent at close time.

2024-09-07ata: libata: Improve CDL resource managementDamien Le Moal
The ncq_sense_buf buffer field of struct ata_port is allocated and used only for devices that support the Command Duration Limits (CDL) feature. However, the cdl buffer of struct ata_device, which is used to cache the command duration limits log page for devices supporting CDL is always allocated as part of struct ata_device, which is wasteful of memory for devices that do not support this feature. Clean this up by defining both buffers as part of the new ata_cdl structure and allocating this structure only for devices that support the CDL feature. This new structure is attached to struct ata_device using the cdl pointer. The functions ata_dev_init_cdl_resources() and ata_dev_cleanup_cdl_resources() are defined to manage this new structure allocation, initialization and freeing when a port is removed or a device disabled. ata_dev_init_cdl_resources() is called from ata_dev_config_cdl() only for devices that support CDL. ata_dev_cleanup_cdl_resources() is called from ata_dev_free_resources() to free the ata_cdl structure when a device is being disabled by EH. Note that the name of the former cdl log buffer of struct ata_device is changed to desc_log_buf to make it clearer that it is a buffer for the limit descriptors log page. This change reduces the size of struct ata_device, thus reducing memory usage for ATA devices that do not support the CDL feature.

2024-09-07ata: libata: Introduce ata_dev_free_resourcesDamien Le Moal
Introduce the function ata_dev_free_resources() to free the resources allocated to support a device features. For now, this function is reduced to calling zpodd_exit() for devices that have this feature enabled. ata_dev_free_resources() is called from ata_eh_dev_disable() as this function is always called for all devices attached to a port that is being detached and for devices that are being disabled due to being removed (detached) from the system or due to errors. With this change, the call to zpodd_exit() done in ata_port_detach() and ata_scsi_handle_link_detach() are removed as these functions remove all devices attached to the link or port using libata EH, thus resulting in ata_eh_dev_disable() being called and the zpodd_exit() function being executed.

2024-09-07ata: libata: Move sector_buf from struct ata_port to struct ata_deviceDamien Le Moal
The 512B buffer sector_buf field of struct ata_port is used for scanning devices as well as during error recovery with ata EH. This buffer is thus useless if a port does not have a device connected to it. And also given that commands using this buffer are issued to devices, and not to ports, move this buffer definition from struct ata_port to struct ata_device. This change slightly increases system memory usage for systems using a port-multiplier as in that case we do not need a per-device buffer for scanning devices (PMP does not allow parallel scanning) nor for EH (as when entering EH we are guaranteed that all commands to all devices connected to the PMP have completed or have been aborted). However, this change reduces memory usage on systems that have many ports with only few devices rives connected, which is a much more common use case than the PMP use case.

The function ata_eh_read_sense_success_ncq_log() does more that just reading the sense data for successful NCQ commands log page as it also sets the sense data for all commands listed in the log page. Rename this function to ata_eh_get_ncq_success_sense() to better describe what the function does. Furthermore, since this function is only called from ata_eh_get_success_sense() in libata-eh.c, there is no need to export it and its declaration can be moved to drivers/ata/libata.h. To be consistent with this change, the function ata_eh_read_sense_success_non_ncq() is also renamed to ata_eh_get_non_ncq_success_sense().

Merge series from Andre Przywara <andre.przywara@arm.com>: This is remainder of the AXP717 fix series, containing support for the boost regulator. This is meant to increase the battery voltage to the 5 volts required to provide the USB VBUS power. It's the usual trinity of DT bindings patch (1/3), the MFD part describing the PMIC registers (2/3) and the final patch to model the regulator (3/3). Compared to v2, this drops the merged patches, and just retains the boost related parts. It also changes the internal name of the register to AXP717_MODULE_EN_CONTROL_2, since there is another control register we will need later for battery support.

2024-09-06drm/amdkfd: fix missed queue reset on queue destroyJonathan Kim
If a queue is being destroyed but causes a HWS hang on removal, the KFD may issue an unnecessary gpu reset if the destroyed queue can be fixed by a queue reset. This is because the queue has been removed from the KFD's queue list prior to the preemption action on destroy so the reset call will fail to match the HQD PQ reset information against the KFD's queue record to do the actual reset. To fix this, deactivate the queue prior to preemption since it's being destroyed anyways and remove the queue from the KFD's queue list after preemption.

cleaner shader This commit replaces the use of amdgpu_job_submit_direct which submits the job to the ring directly, with drm_sched_entity in the cleaner shader job submission process. The change allows the GPU scheduler to manage the cleaner shader job. - The job is then submitted to the GPU using the drm_sched_entity_push_job function, which allows the GPU scheduler to manage the job. This change improves the reliability of the cleaner shader job submission process by leveraging the capabilities of the GPU scheduler.

2024-09-06drm/amd/display: Avoid race between dcn35_set_drr() and dc_state_destruct()Tobias Jakobi
dc_state_destruct() nulls the resource context of the DC state. The pipe context passed to dcn35_set_drr() is a member of this resource context. If dc_state_destruct() is called parallel to the IRQ processing (which calls dcn35_set_drr() at some point), we can end up using already nulled function callback fields of struct stream_resource. The logic in dcn35_set_drr() already tries to avoid this, by checking tg against NULL. But if the nulling happens exactly after the NULL check and before the next access, then we get a race. Avoid this by copying tg first to a local variable, and then use this variable for all the operations. This should work, as long as nobody frees the resource pool where the timing generators live.
