2022-10-05cifs: Replace a couple of one-element arrays with flexible-array membersGustavo A. R. Silva
One-element arrays are deprecated, and we are replacing them with flexible array members instead. So, replace one-element arrays with flexible-array member in structs negotiate_req and extended_response, and refactor the rest of the code, accordingly. Also, make use of the DECLARE_FLEX_ARRAY() helper to declare flexible array member EncryptionKey in union u. This new helper allows for flexible-array members in unions. Change pointer notation to proper array notation in a call to memcpy() where flexible-array member DialectsArray is being used as destination argument. Important to mention is that doing a build before/after this patch results in no binary output differences. This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy() and help us make progress towards globally enabling -fstrict-flex-arrays=3 [1].

2022-10-05smb3: do not log confusing message when server returns no network interfacesSteve French
Some servers can return an empty network interface list so, unless multichannel is requested, no need to log an error for this, and when multichannel is requested on mount but no interfaces, log something less confusing. For this case change parse_server_interfaces: malformed interface info to empty network interface list returned by server localhost Also do not relog this error every ten minutes (only log on mount, once) Cc: <stable@vger.kernel.org> Reviewed-by: Paulo Alcantara (SUSE) <pc@cjr.nz> Signed-off-by: Steve French <stfrench@microsoft.com>

2022-09-24Merge branch 'for-6.0/dax' into libnvdimm-fixesDan Williams
Pick up another "Soft Reservation" fix for v6.0-final on top of some straggling nvdimm fixes that missed v5.19.
2022-09-24devdax: Fix soft-reservation memory descriptionDan Williams
The "hmem" platform-devices that are created to represent the platform-advertised "Soft Reserved" memory ranges end up inserting a resource that causes the iomem_resource tree to look like this: 340000000-43fffffff : hmem.0 340000000-43fffffff : Soft Reserved 340000000-43fffffff : dax0.0 This is because insert_resource() reparents ranges when they completely intersect an existing range. This matters because code that uses region_intersects() to scan for a given IORES_DESC will only check that top-level 'hmem.0' resource and not the 'Soft Reserved' descendant. So, to support EINJ (via einj_error_inject()) to inject errors into memory hosted by a dax-device, be sure to describe the memory as IORES_DESC_SOFT_RESERVED. This is a follow-on to: commit b13a3e5fd40b ("ACPI: APEI: Fix _EINJ vs EFI_MEMORY_SP") ...that fixed EINJ support for "Soft Reserved" ranges in the first instance.

2022-09-23io_uring: ensure that cached task references are always put on exitJens Axboe
io_uring caches task references to avoid doing atomics for each of them per request. If a request is put from the same task that allocated it, then we can maintain a per-ctx cache of them. This obviously relies on io_uring always pruning caches in a reliable way, and there's currently a case off io_uring fd release where we can miss that. One example is a ring setup with IOPOLL, which relies on the task polling for completions, which will free them. However, if such a task submits a request and then exits or closes the ring without reaping the completion, then ring release will reap and put. If release happens from that very same task, the completed request task refs will get put back into the cache pool. This is problematic, as we're now beyond the point of pruning caches. Manually drop these caches after doing an IOPOLL reap. This releases references from the current task, which is enough. If another task happens to be doing the release, then the caching will not be triggered and there's no issue.

The first is a revert of the "fw_devlink.strict=1" default option that we keep trying to enable, but we keep finding platforms that this just breaks everything on. So again, we need it reverted and hopefully it can be worked on in future releases. The second is a sysfs file-size bugfix that resolves an issue that many people are starting to hit as the fix it is fixing also was backported to stable kernels. The util-linux developers are starting to get bugreports about sysfs files that contain no data because of this problem, and this fix which has been in linux-next in the bitfield tree for a long time, resolves it.

2022-09-23vmlinux.lds.h: CFI: Reduce alignment of jump-table to function alignmentWill Deacon
Due to undocumented, hysterical raisins on x86, the CFI jump-table sections in .text are needlessly aligned to PMD_SIZE in the vmlinux linker script. When compiling a CFI-enabled arm64 kernel with a 64KiB page-size, a PMD maps 512MiB of virtual memory and so the .text section increases to a whopping 940MiB and blows the final Image up to 960MiB. Others report a link failure. Since the CFI jump-table requires only instruction alignment, reduce the alignment directives to function alignment for parity with other parts of the .text section. This reduces the size of the .text section for the aforementioned 64KiB page size arm64 kernel to 19MiB for a much more reasonable total Image size of 39MiB.
