2022-10-24videodev2.h: add p_s32 and p_s64 pointersHans Verkuil
Added p_s32 and p_s64 pointers to the union in struct v4l2_ext_control to simplify INTEGER and INTEGER64 control array support. Internally the control framework handles such arrays just fine, but userspace is missing corresponding pointers to access array elements of these types. The internal union v4l2_ctrl_ptr which the control framework uses already has these types, they just were never added to the public API. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>

2022-10-24net: add a refcount tracker for kernel socketsEric Dumazet
Commit ffa84b5ffb37 ("net: add netns refcount tracker to struct sock") added a tracker to sockets, but did not track kernel sockets. We still have syzbot reports hinting about netns being destroyed while some kernel TCP sockets had not been dismantled. This patch tracks kernel sockets, and adds a ref_tracker_dir_print() call to net_free() right before the netns is freed. Normally, each layer is responsible for properly releasing its kernel sockets before last call to net_free().

2022-10-24udp: track the forward memory release threshold in an hot cachelinePaolo Abeni
When the receiver process and the BH runs on different cores, udp_rmem_release() experience a cache miss while accessing sk_rcvbuf, as the latter shares the same cacheline with sk_forward_alloc, written by the BH. With this patch, UDP tracks the rcvbuf value and its update via custom SOL_SOCKET socket options, and copies the forward memory threshold value used by udp_rmem_release() in a different cacheline, already accessed by the above function and uncontended. Since the UDP socket init operation grown a bit, factor out the common code between v4 and v6 in a shared helper. Overall the above give a 10% peek throughput increase under UDP flood.

2022-10-24efi: random: reduce seed size to 32 bytesArd Biesheuvel
We no longer need at least 64 bytes of random seed to permit the early crng init to complete. The RNG is now based on Blake2s, so reduce the EFI seed size to the Blake2s hash size, which is sufficient for our purposes. While at it, drop the READ_ONCE(), which was supposed to prevent size from being evaluated after seed was unmapped. However, this cannot actually happen, so READ_ONCE() is unnecessary here.

Commit bfca3dd3d068 ("kernel/utsname_sysctl.c: print kernel arch") added a new entry to the uts_kern_table[] array, but didn't update the UTS_PROC_xyz enumerators of older entries, breaking anything that used them.

2022-10-22usb: gadget: uvc: default the ctrl request interface offsetsMichael Grzeschik
For the userspace it is needed to distinguish between requests for the control or streaming interface. The userspace would have to parse the configfs to know which interface index it has to compare the ctrl requests against. Since the interface numbers are not fixed, e.g. for composite gadgets, the interface offset depends on the setup. The kernel has this information when handing over the ctrl request to the userspace. This patch removes the offset from the interface numbers and expose the default interface defines in the uapi g_uvc.h.

2022-10-22scsi: core: Support failing requests while recoveringBart Van Assche
The current behavior for SCSI commands submitted while error recovery is ongoing is to retry command submission after error recovery has finished. See also the scsi_host_in_recovery() check in scsi_host_queue_ready(). Add support for failing SCSI commands while host recovery is in progress. This functionality will be used to fix a deadlock in the UFS driver.

2022-10-22scsi: core: Change the return type of .eh_timed_out()Bart Van Assche
Commit 6600593cbd93 ("block: rename BLK_EH_NOT_HANDLED to BLK_EH_DONE") made it impossible for .eh_timed_out() implementations to call scsi_done() without causing a crash. Restore support for SCSI timeout handlers to call scsi_done() as follows: * Change all .eh_timed_out() handlers as follows: - Change the return type into enum scsi_timeout_action. - Change BLK_EH_RESET_TIMER into SCSI_EH_RESET_TIMER. - Change BLK_EH_DONE into SCSI_EH_NOT_HANDLED. * In scsi_timeout(), convert the SCSI_EH_* values into BLK_EH_* values.

blk-mq already provides a unique tag per request. Some libsas LLDDs - like hisi_sas - already use this tag as the unique per-I/O HW tag. Add a common function to provide the request associated with a sas_task for all libsas LLDDs.

2022-10-21EDAC/ghes: Make ghes_edac a proper moduleJia He
Commit dc4e8c07e9e2 ("ACPI: APEI: explicit init of HEST and GHES in apci_init()") introduced a bug leading to ghes_edac_register() to be invoked before edac_init(). Because at that time the bus "edac" hadn't been even registered, this created sysfs nodes as /devices/mc0 instead of /sys/devices/system/edac/mc/mc0 on an Ampere eMag server. Fix this by turning ghes_edac into a proper module. The list of GHES devices returned is not protected from being modified concurrently but it is pretty static as it gets created only during GHES init and latter is not a module so...

2022-10-21ASoC: SOF: Intel/IPC4: Support for external firmware librariesMark Brown
Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>: In IPC4 all DSP loadable executable is a 'library' containing modules. The main or basefw is also a library which contains multiple modules. IPC4 allows to use loadable libraries to extend the functionality of the booted basefw. This series adds support for loading external libraries in case they are needed by the loaded topology file. The libraries must be placed to a specific firmware directory (fw_lib_prefix), which is: intel/avs-lib|sof-ipc4-lib/ followed by the platform name and in case of community key use a 'community' directory. For example for upx-i11 (community key): intel/avs-lib/tgl/community is the default path. The name of the library should be the UUID of the module it contains since the library loading is going to look for the file as <module_UUID>.bin In case there is a need to bundle multiple modules into single library, symlinks can be used to point to the file: module_boundle.bin <UUID1>.bin -> module_boundle.bin <UUID2>.bin -> module_boundle.bin <UUID3>.bin -> module_boundle.bin But note that in this case all modules will be loaded to the DSP since only the whole library can be loaded, not individual modules.
