2024-09-27[tree-wide] finally take no_llseek outAl Viro1-1/+0
no_llseek had been defined to NULL two years ago, in commit 868941b14441 ("fs: remove no_llseek") To quote that commit, At -rc1 we'll need do a mechanical removal of no_llseek - git grep -l -w no_llseek | grep -v porting.rst | while read i; do sed -i '/\<no_llseek\>/d' $i done would do it. Unfortunately, that hadn't been done. Linus, could you do that now, so that we could finally put that thing to rest? All instances are of the form .llseek = no_llseek, so it's obviously safe.

gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs Pull misc vfs updates from Christian Brauner: "This contains the usual pile of misc updates: Features: - Add F_CREATED_QUERY fcntl() that allows userspace to query whether a file was actually created. Often userspace wants to know whether an O_CREATE request did actually create a file without using O_EXCL. The current logic is that to first attempts to open the file without O_CREAT | O_EXCL and if ENOENT is returned userspace tries again with both flags. If that succeeds all is well. If it now reports EEXIST it retries. That works fairly well but some corner cases make this more involved. If this operates on a dangling symlink the first openat() without O_CREAT | O_EXCL will return ENOENT but the second openat() with O_CREAT | O_EXCL will fail with EEXIST. The reason is that openat() without O_CREAT | O_EXCL follows the symlink while O_CREAT | O_EXCL doesn't for security reasons. So it's not something we can really change unless we add an explicit opt-in via O_FOLLOW which seems really ugly. All available workarounds are really nasty (fanotify, bpf lsm etc) so add a simple fcntl(). - Try an opportunistic lookup for O_CREAT. Today, when opening a file we'll typically do a fast lookup, but if O_CREAT is set, the kernel always takes the exclusive inode lock. This was likely done with the expectation that O_CREAT means that we always expect to do the create, but that's often not the case. Many programs set O_CREAT even in scenarios where the file already exists (see related F_CREATED_QUERY patch motivation above). The series contained in the pr rearranges the pathwalk-for-open code to also attempt a fast_lookup in certain O_CREAT cases. If a positive dentry is found, the inode_lock can be avoided altogether and it can stay in rcuwalk mode for the last step_into. - Expose the 64 bit mount id via name_to_handle_at() Now that we provide a unique 64-bit mount ID interface in statx(2), we can now provide a race-free way for name_to_handle_at(2) to provide a file handle and corresponding mount without needing to worry about racing with /proc/mountinfo parsing or having to open a file just to do statx(2). While this is not necessary if you are using AT_EMPTY_PATH and don't care about an extra statx(2) call, users that pass full paths into name_to_handle_at(2) need to know which mount the file handle comes from (to make sure they don't try to open_by_handle_at a file handle from a different filesystem) and switching to AT_EMPTY_PATH would require allocating a file for every name_to_handle_at(2) call - Add a per dentry expire timeout to autofs There are two fairly well known automounter map formats, the autofs format and the amd format (more or less System V and Berkley). Some time ago Linux autofs added an amd map format parser that implemented a fair amount of the amd functionality. This was done within the autofs infrastructure and some functionality wasn't implemented because it either didn't make sense or required extra kernel changes. The idea was to restrict changes to be within the existing autofs functionality as much as possible and leave changes with a wider scope to be considered later. One of these changes is implementing the amd options: 1) "unmount", expire this mount according to a timeout (same as the current autofs default). 2) "nounmount", don't expire this mount (same as setting the autofs timeout to 0 except only for this specific mount) . 3) "utimeout=<seconds>", expire this mount using the specified timeout (again same as setting the autofs timeout but only for this mount) To implement these options per-dentry expire timeouts need to be implemented for autofs indirect mounts. This is because all map keys (mounts) for autofs indirect mounts use an expire timeout stored in the autofs mount super block info. structure and all indirect mounts use the same expire timeout. Fixes: - Fix missing fput for FSCONFIG_SET_FD in autofs - Use param->file for FSCONFIG_SET_FD in coda - Delete the 'fs/netfs' proc subtreee when netfs module exits - Make sure that struct uid_gid_map fits into a single cacheline - Don't flush in-flight wb switches for superblocks without cgroup writeback - Correcting the idmapping mount example in the idmapping documentation - Fix a race between evice_inodes() and find_inode() and iput() - Refine the show_inode_state() macro definition in writeback code - Prevent dump_mapping() from accessing invalid dentry.d_name.name - Show actual source for debugfs in /proc/mounts - Annotate data-race of busy_poll_usecs in eventpoll - Don't WARN for racy path_noexec check in exec code - Handle OOM on mnt_warn_timestamp_expiry() - Fix some spelling in the iomap design documentation - Fix typo in procfs comment - Fix typo in fs/namespace.c comment Cleanups: - Add the VFS git tree to the MAINTAINERS file - Move FMODE_UNSIGNED_OFFSET to fop_flags freeing up another f_mode bit in struct file bringing us to 5 free f_mode bits - Remove the __I_DIO_WAKEUP bit from i_state flags as we can simplify the wait mechanism - Remove the unused path_put_init() helper - Replace a __u32 with u32 for s_fsnotify_mask as __u32 is uapi specific - Replace the unsigned long i_state member with a u32 i_state member in struct inode freeing up 4 bytes in struct inode.

2024-09-16drm/i915/dp: Fix AUX IO power enabling for eDP PSRImre Deak3-1/+22
Panel Self Refresh on eDP requires the AUX IO power to be enabled whenever the output (main link) is enabled. This is required by the AUX_PHY_WAKE/ML_PHY_LOCK signaling initiated by the HW automatically to re-enable the main link after it got disabled in power saving states (see eDP v1.4b, sections 5.1, 6.1.3.3.1.1). The Panel Replay mode on non-eDP outputs on the other hand is only supported by keeping the main link active, thus not requiring the above AUX_PHY_WAKE/ML_PHY_LOCK signaling (eDP v1.4b, section 6.1.3.3.1.2). Thus enabling the AUX IO power for this case is not required either. Based on the above enable the AUX IO power only for eDP/PSR outputs. Bspec: 49274, 53370 v2: - Add a TODO comment to adjust the requirement for AUX IO based on whether the ALPM/main-link off mode gets enabled.

It may be possible for the sum of the values derived from i915_ggtt_offset() and __get_parent_scratch_offset()/ i915_ggtt_offset() to go over the u32 limit before being assigned to wq offsets of u64 type. Mitigate these issues by expanding one of the right operands to u64 to avoid any overflow issues just in case. Found by Linux Verification Center (linuxtesting.org) with static analysis tool SVACE.

2024-09-02drm/i915: Fix readout degamma_lut mismatch on ilk/snbVille Syrjälä1-5/+26
On ilk/snb the pipe may be configured to place the LUT before or after the CSC depending on various factors, but as there is only one LUT (no split mode like on IVB+) we only advertise a gamma_lut and no degamma_lut in the uapi to avoid confusing userspace. This can cause a problem during readout if the VBIOS/GOP enabled the LUT in the pre CSC configuration. The current code blindly assigns the results of the readout to the degamma_lut, which will cause a failure during the next atomic_check() as we aren't expecting anything to be in degamma_lut since it's not visible to userspace. Fix the problem by assigning whatever LUT we read out from the hardware into gamma_lut.

2024-09-02drm/i915: Do not attempt to load the GSC multiple timesDaniele Ceraolo Spurio2-1/+6
If the GSC FW fails to load the GSC HW hangs permanently; the only ways to recover it are FLR or D3cold entry, with the former only being supported on driver unload and the latter only on DGFX, for which we don't need to load the GSC. Therefore, if GSC fails to load there is no need to try again because the HW is stuck in the error state and the submission to load the FW would just hang the GSCCS. Note that, due to wa_14015076503, on MTL the GuC escalates all GSCCS hangs to full GT resets, which would trigger a new attempt to load the GSC FW in the post-reset HW re-init; this issue is also fixed by not attempting to load the GSC FW after an error.

2024-08-29drm/i915: deprecate the i915.modeset module parameterJani Nikula2-2/+7
The i915.modeset parameter doesn't really provide any useful benefit over the nomodeset kernel parameter. Anything that i915.modeset does can be achieved via nomodeset or not probing i915 at all. Unfortunately, the i915.modeset parameter is widely referenced on various forums, and removing it is not that simple. Start off by deprecating it in the module parameter documentation, and logging a warning message on non-default values.

2024-08-29drm/i915: fail module probe on nomodeset and i915.modeset=0Jani Nikula1-2/+1
Since commit b30324adaf8d ("drm/i915: Deprecated UMS support") we've silently failed the probe, without propagating errors, on nomodeset and i915.modeset=0. This has been to not upset userspace. See the above commit for details. Since then, we've removed both the UMS and KMS kconfig options in commit 03dae59c72ff ("drm/i915: Ditch UMS config option") and commit fd930478fb79 ("drm/i915: Remove KMS Kconfig option") respectively. Another ten years or so have passed. Continue with the deprecation by actually failing the probe with nomodeset and i915.modeset=0.
