* ext4: bail out of ext4_xattr_ibody_get() fails for any reasonTheodore Ts'o2023-05-171-1/+1
| | | | | | | | | | | | commit 2a534e1d0d1591e951f9ece2fb460b2ff92edabd upstream. In ext4_update_inline_data(), if ext4_xattr_ibody_get() fails for any reason, it's best if we just fail as opposed to stumbling on, especially if the failure is EFSCORRUPTED.

* ext4: add bounds checking in get_max_inline_xattr_value_size()Theodore Ts'o2023-05-171-1/+11
| | | | | | | | | | | | | | | | commit 2220eaf90992c11d888fe771055d4de330385f01 upstream. Normally the extended attributes in the inode body would have been checked when the inode is first opened, but if someone is writing to the block device while the file system is mounted, it's possible for the inode table to get corrupted. Add bounds checking to avoid reading beyond the end of allocated memory if this happens.

* ext4: fix deadlock when converting an inline directory in nojournal modeTheodore Ts'o2023-05-171-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit f4ce24f54d9cca4f09a395f3eecce20d6bec4663 upstream. In no journal mode, ext4_finish_convert_inline_dir() can self-deadlock by calling ext4_handle_dirty_dirblock() when it already has taken the directory lock. There is a similar self-deadlock in ext4_incvert_inline_data_nolock() for data files which we'll fix at the same time. A simple reproducer demonstrating the problem: mke2fs -Fq -t ext2 -O inline_data -b 4k /dev/vdc 64 mount -t ext4 -o dirsync /dev/vdc /vdc cd /vdc mkdir file0 cd file0 touch file0 touch file1 attr -s BurnSpaceInEA -V abcde . touch supercalifragilisticexpialidocious Cc: stable@kernel.org Link: https://lore.kernel.org/r/20230507021608.1290720-1-tytso@mit.edu Reported-by: syzbot+91dccab7c64e2850a4e5@syzkaller.appspotmail.com Link: https://syzkaller.appspot.com/bug?id=ba84cc80a9491d65416bc7877e1650c87530fe8a Signed-off-by: Theodore Ts'o <tytso@mit.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* ext4: improve error handling from ext4_dirhash()Theodore Ts'o2023-05-172-17/+42
| | | | | | | | | | | | | | | | | | | | commit 4b3cb1d108bfc2aebb0d7c8a52261a53cf7f5786 upstream. The ext4_dirhash() will *almost* never fail, especially when the hash tree feature was first introduced. However, with the addition of support of encrypted, casefolded file names, that function can most certainly fail today. So make sure the callers of ext4_dirhash() properly check for failures, and reflect the errors back up to their callers.

* ext4: improve error recovery code paths in __ext4_remount()Theodore Ts'o2023-05-171-3/+10
| | | | | | | | | | | | | | | | | | commit 4c0b4818b1f636bc96359f7817a2d8bab6370162 upstream. If there are failures while changing the mount options in __ext4_remount(), we need to restore the old mount options. This commit fixes two problem. The first is there is a chance that we will free the old quota file names before a potential failure leading to a use-after-free. The second problem addressed in this commit is if there is a failed read/write to read-only transition, if the quota has already been suspended, we need to renable quota handling.

* ext4: check iomap type only if ext4_iomap_begin() does not failBaokun Li2023-05-171-1/+1
| | | | | | | | | | | | | | | | | | | | commit fa83c34e3e56b3c672af38059e066242655271b1 upstream. When ext4_iomap_overwrite_begin() calls ext4_iomap_begin() map blocks may fail for some reason (e.g. memory allocation failure, bare disk write), and later because "iomap->type ! = IOMAP_MAPPED" triggers WARN_ON(). When ext4 iomap_begin() returns an error, it is normal that the type of iomap->type may not match the expectation. Therefore, we only determine if iomap->type is as expected when ext4_iomap_begin() is executed successfully.

* ext4: avoid deadlock in fs reclaim with page writebackJan Kara2023-05-173-13/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 00d873c17e29cc32d90ca852b82685f1673acaa5 upstream. Ext4 has a filesystem wide lock protecting ext4_writepages() calls to avoid races with switching of journalled data flag or inode format. This lock can however cause a deadlock like: CPU0 CPU1 ext4_writepages() percpu_down_read(sbi->s_writepages_rwsem); ext4_change_inode_journal_flag() percpu_down_write(sbi->s_writepages_rwsem); - blocks, all readers block from now on ext4_do_writepages() ext4_init_io_end() kmem_cache_zalloc(io_end_cachep, GFP_KERNEL) fs_reclaim frees dentry... dentry_unlink_inode() iput() - last ref => iput_final() - inode dirty => write_inode_now()... ext4_writepages() tries to acquire sbi->s_writepages_rwsem and blocks forever Make sure we cannot recurse into filesystem reclaim from writeback code to avoid the deadlock.

* ext4: fix data races when using cached status extentsJan Kara2023-05-171-17/+13
| | | | | | | | | | | | | | | | | | | | commit 492888df0c7b42fc0843631168b0021bc4caee84 upstream. When using cached extent stored in extent status tree in tree->cache_es another process holding ei->i_es_lock for reading can be racing with us setting new value of tree->cache_es. If the compiler would decide to refetch tree->cache_es at an unfortunate moment, it could result in a bogus in_range() check. Fix the possible race by using READ_ONCE() when using tree->cache_es only under ei->i_es_lock for reading.

* drm/i915: disable sampler indirect state in bindless heapLionel Landwerlin2023-05-172-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 81900e3a37750d8c6ad705045310e002f6dd0356 ] By default the indirect state sampler data (border colors) are stored in the same heap as the SAMPLER_STATE structure. For userspace drivers that can be 2 different heaps (dynamic state heap & bindless sampler state heap). This means that border colors have to copied in 2 different places so that the same SAMPLER_STATE structure find the right data. This change is forcing the indirect state sampler data to only be in the dynamic state pool (more convenient for userspace drivers, they only have to have one copy of the border colors). This is reproducing the behavior of the Windows drivers.

For that it may be that the table needs to contain holes, making (1) even worse.

* drm/msm/adreno: adreno_gpu: Use suspend() instead of idle() on load errorKonrad Dybcio2023-05-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 3eeca5e5f3100435b06a5b5d86daa3d135a8a4bd upstream. The adreno_load_gpu() path is guarded by an error check on adreno_load_fw(). This function is responsible for loading Qualcomm-only-signed binaries (e.g. SQE and GMU FW for A6XX), but it does not take the vendor-signed ZAP blob into account. By embedding the SQE (and GMU, if necessary) firmware into the initrd/kernel, we can trigger and unfortunate path that would not bail out early and proceed with gpu->hw_init(). That will fail, as the ZAP loader path will not find the firmware and return back to adreno_load_gpu(). This error path involves pm_runtime_put_sync() which then calls idle() instead of suspend(). This is suboptimal, as it means that we're not going through the clean shutdown sequence. With at least A619_holi, this makes the GPU not wake up until it goes through at least one more start-fail-stop cycle. The pm_runtime_put_sync that appears in the error path actually does not guarantee that because of the earlier enabling of runtime autosuspend. Fix that by using pm_runtime_put_sync_suspend to force a clean shutdown. Test cases: 1. All firmware baked into kernel 2. error loading ZAP fw in initrd -> load from rootfs at DE start Both succeed on A619_holi (SM6375) and A630 (SDM845).

| | | | | | | | | | | | | | | | | | | | | commit 17d793f3ed53080dab6bbeabfc82de890c901001 upstream. To fully utilize the BT polling/refresh rate, a few input events are sent together to reduce event delay. This causes issue to the timestamp generated by input_sync since all the events in the same packet would pretty much have the same timestamp. This patch inserts time interval to the events by averaging the total time used for sending the packet. This decision was mainly based on observing the actual time interval between each BT polling. The interval doesn't seem to be constant, due to the network and system environment. So, using solutions other than averaging doesn't end up with valid timestamps.

[Description] - Due to bandwidth / arbitration issues at 200Mhz DCFCLK, we want to enforce minimum 60us of prefetch to avoid intermittent underflow issues - Since 60us prefetch is already enforced for UCLK DPM0, and many DCFCLK's > 200Mhz are mapped to UCLK DPM1, in theory there should not be any UCLK DPM regressions by enforcing greater prefetch Reviewed-by: Nevenko Stupar <Nevenko.Stupar@amd.com> Reviewed-by: Jun Lei <Jun.Lei@amd.com> Cc: Mario Limonciello <mario.limonciello@amd.com> Cc: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org Acked-by: Alex Hung <alex.hung@amd.com> Signed-off-by: Alvin Lee <Alvin.Lee2@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

This is because the DPPCLK is stopped during the middle of an optimize_bandwidth sequence during commit_minimal_transition without going through plane power down/power up. [How] The intent of a 0Hz DPP clock through update_clocks is to disable the DTO. This differs from the behavior of stopping the DPPCLK entirely (utilizing a 0Hz clock on some ASIC) so it's better to move this logic to reside next to plane power up/power down where we gate the HUBP/DPP DOMAIN. The new sequence should be: Power down: PG enabled -> RCO on Power up: RCO off -> PG disabled Rename power_on_plane to power_on_plane_resources to reflect the actual operation that's occurring.
