btrfs: remove pointless readahead callback wrapper
There's no point in having a static readahead callback in inode.c that does nothing besides calling extent_readahead() from extent_io.c. So just remove the callback at inode.c and rename extent_readahead() to btrfs_readahead().

btrfs: locking: rename __btrfs_tree_lock() and __btrfs_tree_read_lock()
The __btrfs_tree_lock() and __btrfs_tree_read_lock() are using a naming with a double underscore prefix, which is specially not proper for exported functions. Remove the double underscore prefix from their name and add the "_nested" suffix.

btrfs: locking: inline btrfs_tree_lock() and btrfs_tree_read_lock()
The functions btrfs_tree_lock() and btrfs_tree_read_lock() are very trivial so that can be made inline and avoid call overhead, as they are very often called inside critical sections (when searching a btree for example, attempting to lock a child node/leaf while holding a lock on the parent). So make them static inline, which even reduces the size of the btrfs module a little bit. Before this change: $ size fs/btrfs/btrfs.ko text data bss dec hex filename 1718786 156276 16920 1891982 1cde8e fs/btrfs/btrfs.ko After this change: $ size fs/btrfs/btrfs.ko text data bss dec hex filename 1718650 156260 16920 1891830 1cddf6 fs/btrfs/btrfs.ko Running fs_mark also showed a tiny improvement with this script: $ cat test.sh #!/bin/bash DEV=/dev/nullb0 MNT=/mnt/nullb0 FILES=100000 THREADS=$(nproc --all) echo "performance" | \ tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor umount $DEV &> /dev/null mkfs.btrfs -f $DEV mount $DEV $MNT OPTS="-S 0 -L 5 -n $FILES -s 0 -t $THREADS -k" for ((i = 1; i <= $THREADS; i++)); do OPTS="$OPTS -d $MNT/d$i" done fs_mark $OPTS umount $MNT Before this change: FSUse% Count Size Files/sec App Overhead 10 1200000 0 180894.0 10705410 16 2400000 0 228211.4 10765738 23 3600000 0 215969.6 11011072 30 4800000 0 199077.1 11145587 46 6000000 0 176624.1 11658470 After this change: FSUse% Count Size Files/sec App Overhead 10 1200000 0 185312.3 10708377 16 2400000 0 229320.4 10858013 23 3600000 0 217958.7 11006167 30 4800000 0 205122.9 11112899 46 6000000 0 178039.1 11438852 Reviewed-by: Anand Jain <anand.jain@oracle.com> Reviewed-by: Johannes Thumshirn <johannes.thumshirn@wdc.com> Reviewed-by: Qu Wenruo <wqu@suse.com> Signed-off-by: Filipe Manana <fdmanana@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com> |

btrfs: remove pointless BUG_ON() when creating snapshot
When creating a snapshot we first check with btrfs_lookup_dir_item() if there is a name collision in the parent directory and then return an error if there's a collision. Then later on when trying to insert a dir item for the snapshot we BUG_ON() if the return value is -EEXIST or -EOVERFLOW: static noinline int create_pending_snapshot(...) { (...) /* check if there is a file/dir which has the same name. */ dir_item = btrfs_lookup_dir_item(...); (...) ret = btrfs_insert_dir_item(...); /* We have check then name at the beginning, so it is impossible. */ BUG_ON(ret == -EEXIST || ret == -EOVERFLOW); if (ret) { btrfs_abort_transaction(trans, ret); goto fail; } (...) } It's impossible to get the -EEXIST because we previously checked for a potential collision with btrfs_lookup_dir_item() and we know that after that no one could have added a colliding name because at this point the transaction is in its critical section, state TRANS_STATE_COMMIT_DOING, so no one can join this transaction to add a colliding name and neither can anyone start a new transaction to do that. As for the -EOVERFLOW, that can't happen as long as we have the extended references feature enabled, which is a mkfs default for many years now. In either case, the BUG_ON() is excessive as we can properly deal with any error and can abort the transaction and jump to the 'fail' label, in which case we'll also get the useful stack trace (just like a BUG_ON()) from the abort if the error is either -EEXIST or -EOVERFLOW. So remove the BUG_ON().

Reapply "drm/qxl: simplify qxl_fence_wait"
This reverts commit 07ed11afb68d94eadd4ffc082b97c2331307c5ea. Stephen Rostedt reports: "I went to run my tests on my VMs and the tests hung on boot up. Unfortunately, the most I ever got out was: [ 93.607888] Testing event system initcall: OK [ 93.667730] Running tests on all trace events: [ 93.669757] Testing all events: OK [ 95.631064] ------------[ cut here ]------------ Timed out after 60 seconds" and further debugging points to a possible circular locking dependency between the console_owner locking and the worker pool locking. Reverting the commit allows Steve's VM to boot to completion again. [ This may obviously result in the "[TTM] Buffer eviction failed" messages again, which was the reason for that original revert. But at this point this seems preferable to a non-booting system... ] Reported-and-bisected-by: Steven Rostedt <rostedt@goodmis.org> Link: https://lore.kernel.org/all/20240502081641.457aa25f@gandalf.local.home/ Acked-by: Maxime Ripard <mripard@kernel.org> Cc: Alex Constantino <dreaming.about.electric.sheep@gmail.com> Cc: Maxime Ripard <mripard@kernel.org> Cc: Timo Lindfors <timo.lindfors@iki.fi> Cc: Dave Airlie <airlied@redhat.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

epoll: be better about file lifetimes
epoll can call out to vfs_poll() with a file pointer that may race with the last 'fput()'. That would make f_count go down to zero, and while the ep->mtx locking means that the resulting file pointer tear-down will be blocked until the poll returns, it means that f_count is already dead, and any use of it won't actually get a reference to the file any more: it's dead regardless. Make sure we have a valid ref on the file pointer before we call down to vfs_poll() from the epoll routines.

tracing and tracefs fixes for v6.9
- Fix RCU callback of freeing an eventfs_inode. The freeing of the eventfs_inode from the kref going to zero freed the contents of the eventfs_inode and then used kfree_rcu() to free the inode itself. But the contents should also be protected by RCU. Switch to a call_rcu() that calls a function to free all of the eventfs_inode after the RCU synchronization. - The tracing subsystem maps its own descriptor to a file represented by eventfs. The freeing of this descriptor needs to know when the last reference of an eventfs_inode is released, but currently there is no interface for that. Add a "release" callback to the eventfs_inode entry array that allows for freeing of data that can be referenced by the eventfs_inode being opened. Then increment the ref counter for this descriptor when the eventfs_inode file is created, and decrement/free it when the last reference to the eventfs_inode is released and the file is removed. This prevents races between freeing the descriptor and the opening of the eventfs file. - Fix the permission processing of eventfs. The change to make the permissions of eventfs default to the mount point but keep track of when changes were made had a side effect that could cause security concerns. When the tracefs is remounted with a given gid or uid, all the files within it should inherit that gid or uid. But if the admin had changed the permission of some file within the tracefs file system, it would not get updated by the remount. This caused the kselftest of file permissions to fail the second time it is run. The first time, all changes would look fine, but the second time, because the changes were "saved", the remount did not reset them. Create a link list of all existing tracefs inodes, and clear the saved flags on them on a remount if the remount changes the corresponding gid or uid fields. This also simplifies the code by removing the distinction between the toplevel eventfs and an instance eventfs. They should both act the same. They were different because of a misconception due to the remount not resetting the flags. Now that remount resets all the files and directories to default to the root node if a uid/gid is specified, it makes the logic simpler to implement. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZjXxzxQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qqzGAQCX8g7gtngGgwSsWqPW5GmecCifwFja k7cVEDhMYPnDeAEAkYi2ZBgJRkPsWPfMRClDK/DXP4woOo58asxtIxfTMgg= =mCkt -----END PGP SIGNATURE----- Merge tag 'trace-v6.9-rc6-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing and tracefs fixes from Steven Rostedt: - Fix RCU callback of freeing an eventfs_inode.

eventfs: Have "events" directory get permissions from its parent
The events directory gets its permissions from the root inode. But this can cause an inconsistency if the instances directory changes its permissions, as the permissions of the created directories under it should inherit the permissions of the instances directory when directories under it are created. Currently the behavior is: # cd /sys/kernel/tracing # chgrp 1002 instances # mkdir instances/foo # ls -l instances/foo [..] -r--r----- 1 root lkp 0 May 1 18:55 buffer_total_size_kb -rw-r----- 1 root lkp 0 May 1 18:55 current_tracer -rw-r----- 1 root lkp 0 May 1 18:55 error_log drwxr-xr-x 1 root root 0 May 1 18:55 events --w------- 1 root lkp 0 May 1 18:55 free_buffer drwxr-x--- 2 root lkp 0 May 1 18:55 options drwxr-x--- 10 root lkp 0 May 1 18:55 per_cpu -rw-r----- 1 root lkp 0 May 1 18:55 set_event All the files and directories under "foo" has the "lkp" group except the "events" directory. That's because its getting its default value from the mount point instead of its parent. Have the "events" directory make its default value based on its parent's permissions. That now gives: # ls -l instances/foo [..] -rw-r----- 1 root lkp 0 May 1 21:16 buffer_subbuf_size_kb -r--r----- 1 root lkp 0 May 1 21:16 buffer_total_size_kb -rw-r----- 1 root lkp 0 May 1 21:16 current_tracer -rw-r----- 1 root lkp 0 May 1 21:16 error_log drwxr-xr-x 1 root lkp 0 May 1 21:16 events --w------- 1 root lkp 0 May 1 21:16 free_buffer drwxr-x--- 2 root lkp 0 May 1 21:16 options drwxr-x--- 10 root lkp 0 May 1 21:16 per_cpu -rw-r----- 1 root lkp 0 May 1 21:16 set_event Link: https://lore.kernel.org/linux-trace-kernel/20240502200906.161887248@goodmis.org Cc: stable@vger.kernel.org Cc: Masami Hiramatsu <mhiramat@kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Mathieu Desnoyers <mathieu.desnoyers@efficios.com> Cc: Andrew Morton <akpm@linux-foundation.org> Fixes: 8186fff7ab649 ("tracefs/eventfs: Use root and instance inodes as default ownership") Signed-off-by: Steven Rostedt (Google) <rostedt@goodmis.org> |

eventfs: Do not treat events directory different than other directories
Treat the events directory the same as other directories when it comes to permissions. The events directory was considered different because it's dentry is persistent, whereas the other directory dentries are created when accessed. But the way tracefs now does its ownership by using the root dentry's permissions as the default permissions, the events directory can get out of sync when a remount is performed setting the group and user permissions. Remove the special case for the events directory on setting the attributes. This allows the updates caused by remount to work properly as well as simplifies the code.

tracefs: Still use mount point as default permissions for instances
If the instances directory's permissions were never change, then have it and its children use the mount point permissions as the default. Currently, the permissions of instance directories are determined by the instance directory's permissions itself. But if the tracefs file system is remounted and changes the permissions, the instance directory and its children should use the new permission. But because both the instance directory and its children use the instance directory's inode for permissions, it misses the update. To demonstrate this: # cd /sys/kernel/tracing/ # mkdir instances/foo # ls -ld instances/foo drwxr-x--- 5 root root 0 May 1 19:07 instances/foo # ls -ld instances drwxr-x--- 3 root root 0 May 1 18:57 instances # ls -ld current_tracer -rw-r----- 1 root root 0 May 1 18:57 current_tracer # mount -o remount,gid=1002 . # ls -ld instances drwxr-x--- 3 root root 0 May 1 18:57 instances # ls -ld instances/foo/ drwxr-x--- 5 root root 0 May 1 19:07 instances/foo/ # ls -ld current_tracer -rw-r----- 1 root lkp 0 May 1 18:57 current_tracer Notice that changing the group id to that of "lkp" did not affect the instances directory nor its children. It should have been: # ls -ld current_tracer -rw-r----- 1 root root 0 May 1 19:19 current_tracer # ls -ld instances/foo/ drwxr-x--- 5 root root 0 May 1 19:25 instances/foo/ # ls -ld instances drwxr-x--- 3 root root 0 May 1 19:19 instances # mount -o remount,gid=1002 . # ls -ld current_tracer -rw-r----- 1 root lkp 0 May 1 19:19 current_tracer # ls -ld instances drwxr-x--- 3 root lkp 0 May 1 19:19 instances # ls -ld instances/foo/ drwxr-x--- 5 root lkp 0 May 1 19:25 instances/foo/ Where all files were updated by the remount gid update.

tracefs: Reset permissions on remount if permissions are options
There's an inconsistency with the way permissions are handled in tracefs. Because the permissions are generated when accessed, they default to the root inode's permission if they were never set by the user. If the user sets the permissions, then a flag is set and the permissions are saved via the inode (for tracefs files) or an internal attribute field (for eventfs). But if a remount happens that specify the permissions, all the files that were not changed by the user gets updated, but the ones that were are not. If the user were to remount the file system with a given permission, then all files and directories within that file system should be updated. This can cause security issues if a file's permission was updated but the admin forgot about it. They could incorrectly think that remounting with permissions set would update all files, but miss some.

eventfs: Free all of the eventfs_inode after RCU
The freeing of eventfs_inode via a kfree_rcu() callback. But the content of the eventfs_inode was being freed after the last kref. This is dangerous, as changes are being made that can access the content of an eventfs_inode from an RCU loop. Instead of using kfree_rcu() use call_rcu() that calls a function to do all the freeing of the eventfs_inode after a RCU grace period has expired.

eventfs/tracing: Add callback for release of an eventfs_inode
Synthetic events create and destroy tracefs files when they are created and removed. The tracing subsystem has its own file descriptor representing the state of the events attached to the tracefs files. There's a race between the eventfs files and this file descriptor of the tracing system where the following can cause an issue: With two scripts 'A' and 'B' doing: Script 'A': echo "hello int aaa" > /sys/kernel/tracing/synthetic_events while : do echo 0 > /sys/kernel/tracing/events/synthetic/hello/enable done Script 'B': echo > /sys/kernel/tracing/synthetic_events Script 'A' creates a synthetic event "hello" and then just writes zero into its enable file. Script 'B' removes all synthetic events (including the newly created "hello" event). What happens is that the opening of the "enable" file has: { struct trace_event_file *file = inode->i_private; int ret; ret = tracing_check_open_get_tr(file->tr); [..] But deleting the events frees the "file" descriptor, and a "use after free" happens with the dereference at "file->tr". The file descriptor does have a reference counter, but there needs to be a way to decrement it from the eventfs when the eventfs_inode is removed that represents this file descriptor. Add an optional "release" callback to the eventfs_entry array structure, that gets called when the eventfs file is about to be removed. This allows for the creating on the eventfs file to increment the tracing file descriptor ref counter. When the eventfs file is deleted, it can call the release function that will call the put function for the tracing file descriptor. This will protect the tracing file from being freed while a eventfs file that references it is being opened.

The missing support causes the topology iterator to stumble over a NULL pointer and triggers a kernel OOPS on a platform with CXL 1.1 support. The fix bypasses RCH topology as the access_coordinate calculation is not necessary since RCH does not support hotplug and the memory region exported should be covered by the HMAT table already.

btrfs: make sure that WRITTEN is set on all metadata blocks
We previously would call btrfs_check_leaf() if we had the check integrity code enabled, which meant that we could only run the extended leaf checks if we had WRITTEN set on the header flags. This leaves a gap in our checking, because we could end up with corruption on disk where WRITTEN isn't set on the leaf, and then the extended leaf checks don't get run which we rely on to validate all of the item pointers to make sure we don't access memory outside of the extent buffer. However, since 732fab95abe2 ("btrfs: check-integrity: remove CONFIG_BTRFS_FS_CHECK_INTEGRITY option") we no longer call btrfs_check_leaf() from btrfs_mark_buffer_dirty(), which means we only ever call it on blocks that are being written out, and thus have WRITTEN set, or that are being read in, which should have WRITTEN set. Add checks to make sure we have WRITTEN set appropriately, and then make sure __btrfs_check_leaf() always does the item checking. This will protect us from file systems that have been corrupted and no longer have WRITTEN set on some of the blocks. This was hit on a crafted image tweaking the WRITTEN bit and reported by KASAN as out-of-bound access in the eb accessors. The example is a dir item at the end of an eb.

btrfs: qgroup: do not check qgroup inherit if qgroup is disabled
[BUG] After kernel commit 86211eea8ae1 ("btrfs: qgroup: validate btrfs_qgroup_inherit parameter"), user space tool snapper will fail to create snapshot using its timeline feature. [CAUSE] It turns out that, if using timeline snapper would unconditionally pass btrfs_qgroup_inherit parameter (assigning the new snapshot to qgroup 1/0) for snapshot creation. In that case, since qgroup is disabled there would be no qgroup 1/0, and btrfs_qgroup_check_inherit() would return -ENOENT and fail the whole snapshot creation. [FIX] Just skip the check if qgroup is not enabled. This is to keep the older behavior for user space tools, as if the kernel behavior changed for user space, it is a regression of kernel. Thankfully snapper is also fixing the behavior by detecting if qgroup is running in the first place, so the effect should not be that huge.

x86/xen: return a sane initial apic id when running as PV guest
With recent sanity checks for topology information added, there are now warnings issued for APs when running as a Xen PV guest: [Firmware Bug]: CPU 1: APIC ID mismatch. CPUID: 0x0000 APIC: 0x0001 This is due to the initial APIC ID obtained via CPUID for PV guests is always 0. Avoid the warnings by synthesizing the CPUID data to contain the same initial APIC ID as xen_pv_smp_config() is using for registering the APIC IDs of all CPUs.

drm/xe/display: Fix ADL-N detection
Contrary to i915, in xe ADL-N is kept as a different platform, not a subplatform of ADL-P. Since the display side doesn't need to differentiate between P and N, i.e. IS_ALDERLAKE_P_N() is never called, just fixup the compat header to check for both P and N. Moving ADL-N to be a subplatform would be more complex as the firmware loading in xe only handles platforms, not subplatforms, as going forward the direction is to check on IP version rather than platforms/subplatforms. Fix warning when initializing display: xe 0000:00:02.0: [drm:intel_pch_type [xe]] Found Alder Lake PCH ------------[ cut here ]------------ xe 0000:00:02.0: drm_WARN_ON(!((dev_priv)->info.platform == XE_ALDERLAKE_S) && !((dev_priv)->info.platform == XE_ALDERLAKE_P)) And wrong paths being taken on the display side.

x86/xen/smp_pv: Register the boot CPU APIC properly
The topology core expects the boot APIC to be registered from earhy APIC detection first and then again when the firmware tables are evaluated. This is used for detecting the real BSP CPU on a kexec kernel. The recent conversion of XEN/PV to register fake APIC IDs failed to register the boot CPU APIC correctly as it only registers it once. This causes the BSP detection mechanism to trigger wrongly: CPU topo: Boot CPU APIC ID not the first enumerated APIC ID: 0 > 1 Additionally this results in one CPU being ignored. Register the boot CPU APIC twice so that the XEN/PV fake enumeration behaves like real firmware.
