2022-08-16drm/nouveau/kms/nv140-: Disable interlacingLyude Paul
As it turns out: while Nvidia does actually have interlacing knobs on their GPU still pretty much no current GPUs since Volta actually support it. Trying interlacing on these GPUs will result in NVDisplay being quite unhappy like so: nouveau 0000:1f:00.0: disp: chid 0 stat 00004802 reason 4 [INVALID_ARG] mthd 2008 data 00000001 code 00080000 nouveau 0000:1f:00.0: disp: chid 0 stat 10005080 reason 5 [INVALID_STATE] mthd 0200 data 00000001 code 00000001 So let's fix this by following the same behavior Nvidia's driver does and disable interlacing entirely.

2022-08-16gcc-plugins: Undefine LATENT_ENTROPY_PLUGIN when plugin disabled for a fileAndrew Donnellan
Commit 36d4b36b6959 ("lib/nodemask: inline next_node_in() and node_random()") refactored some code by moving node_random() from lib/nodemask.c to include/linux/nodemask.h, thus requiring nodemask.h to include random.h, which conditionally defines add_latent_entropy() depending on whether the macro LATENT_ENTROPY_PLUGIN is defined. This broke the build on powerpc, where nodemask.h is indirectly included in arch/powerpc/kernel/prom_init.c, part of the early boot machinery that is excluded from the latent entropy plugin using DISABLE_LATENT_ENTROPY_PLUGIN. It turns out that while we add a gcc flag to disable the actual plugin, we don't undefine LATENT_ENTROPY_PLUGIN. This leads to the following: CC arch/powerpc/kernel/prom_init.o In file included from ./include/linux/nodemask.h:97, from ./include/linux/mmzone.h:17, from ./include/linux/gfp.h:7, from ./include/linux/xarray.h:15, from ./include/linux/radix-tree.h:21, from ./include/linux/idr.h:15, from ./include/linux/kernfs.h:12, from ./include/linux/sysfs.h:16, from ./include/linux/kobject.h:20, from ./include/linux/pci.h:35, from arch/powerpc/kernel/prom_init.c:24: ./include/linux/random.h: In function 'add_latent_entropy': ./include/linux/random.h:25:46: error: 'latent_entropy' undeclared (first use in this function); did you mean 'add_latent_entropy'? 25 | add_device_randomness((const void *)&latent_entropy, sizeof(latent_entropy)); | ^~~~~~~~~~~~~~ | add_latent_entropy ./include/linux/random.h:25:46: note: each undeclared identifier is reported only once for each function it appears in make[2]: *** [scripts/Makefile.build:249: arch/powerpc/kernel/prom_init.o] Fehler 1 make[1]: *** [scripts/Makefile.build:465: arch/powerpc/kernel] Fehler 2 make: *** [Makefile:1855: arch/powerpc] Error 2 Change the DISABLE_LATENT_ENTROPY_PLUGIN flags to undefine LATENT_ENTROPY_PLUGIN for files where the plugin is disabled.

2022-08-16exec: Replace kmap{,_atomic}() with kmap_local_page()Fabio M. De Francesco
The use of kmap() and kmap_atomic() are being deprecated in favor of kmap_local_page(). There are two main problems with kmap(): (1) It comes with an overhead as mapping space is restricted and protected by a global lock for synchronization and (2) it also requires global TLB invalidation when the kmap’s pool wraps and it might block when the mapping space is fully utilized until a slot becomes available. With kmap_local_page() the mappings are per thread, CPU local, can take page faults, and can be called from any context (including interrupts). It is faster than kmap() in kernels with HIGHMEM enabled. Furthermore, the tasks can be preempted and, when they are scheduled to run again, the kernel virtual addresses are restored and are still valid. Since the use of kmap_local_page() in exec.c is safe, it should be preferred everywhere in exec.c. As said, since kmap_local_page() can be also called from atomic context, and since remove_arg_zero() doesn't (and shouldn't ever) rely on an implicit preempt_disable(), this function can also safely replace kmap_atomic(). Therefore, replace kmap() and kmap_atomic() with kmap_local_page() in fs/exec.c. Tested with xfstests on a QEMU/KVM x86_32 VM, 6GB RAM, booting a kernel with HIGHMEM64GB enabled. Cc: Eric W.

2022-08-16x86: simplify load_unaligned_zeropad() implementationLinus Torvalds
The exception for the "unaligned access at the end of the page, next page not mapped" never happens, but the fixup code ends up causing trouble for compilers to optimize well. clang in particular ends up seeing it being in the middle of a loop, and tries desperately to optimize the exception fixup code that is never really reached. The simple solution is to just move all the fixups into the exception handler itself, which moves it all out of the hot case code, and means that the compiler never sees it or needs to worry about it.

2022-08-16locking/atomic: Make test_and_*_bit() ordered on failureHector Martin
These operations are documented as always ordered in include/asm-generic/bitops/instrumented-atomic.h, and producer-consumer type use cases where one side needs to ensure a flag is left pending after some shared data was updated rely on this ordering, even in the failure case. This is the case with the workqueue code, which currently suffers from a reproducible ordering violation on Apple M1 platforms (which are notoriously out-of-order) that ends up causing the TTY layer to fail to deliver data to userspace properly under the right conditions. This change fixes that bug. Change the documentation to restrict the "no order on failure" story to the _lock() variant (for which it makes sense), and remove the early-exit from the generic implementation, which is what causes the missing barrier semantics in that case. Without this, the remaining atomic op is fully ordered (including on ARM64 LSE, as of recent versions of the architecture spec).

2022-08-16i40e: Fix to stop tx_timeout recovery if GLOBR failsAlan Brady
When a tx_timeout fires, the PF attempts to recover by incrementally resetting. First we try a PFR, then CORER and finally a GLOBR. If the GLOBR fails, then we keep hitting the tx_timeout and incrementing the recovery level and issuing dmesgs, which is both annoying to the user and accomplishes nothing. If the GLOBR fails, then we're pretty much totally hosed, and there's not much else we can do to recover, so this makes it such that we just kill the VSI and stop hitting the tx_timeout in such a case.

2022-08-16IB/iser: Fix login with authenticationSergey Gorenko
The iSER Initiator uses two types of receive buffers: - one big login buffer posted by iser_post_recvl(); - several small message buffers posted by iser_post_recvm(). The login buffer is used at the login phase and full feature phase in the discovery session. It may take a few requests and responses to complete the login phase. The message buffers are only used in the normal operational session at the full feature phase. After the commit referred in the fixes line, the login operation fails if the authentication is enabled. That happens because the Initiator posts a small receive buffer after the first response from Target. So, the next send operation fails because Target's second response does not fit into the small receive buffer. This commit adds additional checks to prevent posting small receive buffers until the full feature phase.

2022-08-16ublk_drv: do not add a re-issued request aborted previously to ioucmd's ↵ZiyangZhang
task_work In ublk_queue_rq(), Assume current request is a re-issued request aborted previously in monitor_work because the ubq_daemon(ioucmd's task) is PF_EXITING. For this request, we cannot call io_uring_cmd_complete_in_task() anymore because at that moment io_uring context may be freed in case that no inflight ioucmd exists. Otherwise, we may cause null-deref in ctx->fallback_work. Add a check on UBLK_IO_FLAG_ABORTED to prevent the above situation. This check is safe and makes sense. Note: monitor_work sets UBLK_IO_FLAG_ABORTED and ends this request (releasing the tag). Then the request is restarted(allocating the tag) and we are here. Since releasing/allocating a tag implies smp_mb(), finding UBLK_IO_FLAG_ABORTED guarantees that here is a re-issued request aborted previously.

This reverts commit 762faee5a2678559d3dc09d95f8f2c54cd0466a7. This has been reported to trip up guests on GCP (Google Cloud). The reason is that virtio_find_vqs_ctx_size is broken on legacy devices. We can in theory fix virtio_find_vqs_ctx_size but in fact the patch itself has several other issues: - It treats unknown speed as < 10G - It leaves userspace no way to find out the ring size set by hypervisor - It tests speed when link is down - It ignores the virtio spec advice: Both \field{speed} and \field{duplex} can change, thus the driver is expected to re-read these values after receiving a configuration change notification. - It is not clear the performance impact has been tested properly Revert the patch for now.

2022-08-15ksmbd: remove unnecessary generic_fillattr in smb2_openHyunchul Lee
Remove unnecessary generic_fillattr to fix wrong AllocationSize of SMB2_CREATE response, And Move the call of ksmbd_vfs_getattr above the place where stat is needed because of truncate. This patch fixes wrong AllocationSize of SMB2_CREATE response. Because ext4 updates inode->i_blocks only when disk space is allocated, generic_fillattr does not set stat.blocks properly for delayed allocation. But ext4 returns the blocks that include the delayed allocation blocks when getattr is called. The issue can be reproduced with commands below: touch ${FILENAME} xfs_io -c "pwrite -S 0xAB 0 40k" ${FILENAME} xfs_io -c "stat" ${FILENAME} 40KB are written, but the count of blocks is 8.

In the uniprocessor case, cpumask_next_wrap() can be simplified, as the number of valid argument combinations is limited: - 'start' can only be 0 - 'n' can only be -1 or 0 The only valid CPU that can then be returned, if any, will be the first one set in the provided 'mask'. For NR_CPUS == 1, include/linux/cpumask.h now provides an inline definition of cpumask_next_wrap(), which will conflict with the one provided by lib/cpumask.c. Make building of lib/cpumask.o again depend on CONFIG_SMP=y (i.e. NR_CPUS > 1) to avoid the re-definition.

2022-08-15nios2: add force_successful_syscall_return()Al Viro
If we use the ancient SysV syscall ABI, we'd better have tell the kernel how to claim that a negative return value is a success. Use ->orig_r2 for that - it's inaccessible via ptrace, so it's a fair game for changes and it's normally[*] non-negative on return from syscall. Set to -1; syscall is not going to be restart-worthy by definition, so we won't interfere with that use either. [*] the only exception is rt_sigreturn(), where we skip the entire messing with r1/r2 anyway.
