8545605 | Eric Biggers | 26 May 2022, 04:04:12 UTC | ext4: fix up test_dummy_encryption handling for new mount API Since ext4 was converted to the new mount API, the test_dummy_encryption mount option isn't being handled entirely correctly, because the needed fscrypt_set_test_dummy_encryption() helper function combines parsing/checking/applying into one function. That doesn't work well with the new mount API, which split these into separate steps. This was sort of okay anyway, due to the parsing logic that was copied from fscrypt_set_test_dummy_encryption() into ext4_parse_param(), combined with an additional check in ext4_check_test_dummy_encryption(). However, these overlooked the case of changing the value of test_dummy_encryption on remount, which isn't allowed but ext4 wasn't detecting until ext4_apply_options() when it's too late to fail. Another bug is that if test_dummy_encryption was specified multiple times with an argument, memory was leaked. Fix this up properly by using the new helper functions that allow splitting up the parse/check/apply steps for test_dummy_encryption.

1e77696 | Kirill A. Shutemov | 14 June 2022, 12:01:35 UTC | x86/tdx: Handle load_unaligned_zeropad() page-cross to a shared page load_unaligned_zeropad() can lead to unwanted loads across page boundaries. The unwanted loads are typically harmless. But, they might be made to totally unrelated or even unmapped memory. load_unaligned_zeropad() relies on exception fixup (#PF, #GP and now #VE) to recover from these unwanted loads. In TDX guests, the second page can be shared page and a VMM may configure it to trigger #VE. The kernel assumes that #VE on a shared page is an MMIO access and tries to decode instruction to handle it. In case of load_unaligned_zeropad() it may result in confusion as it is not MMIO access. Fix it by detecting split page MMIO accesses and failing them. load_unaligned_zeropad() will recover using exception fixups. The issue was discovered by analysis and reproduced artificially. It was not triggered during testing. [ dhansen: fix up changelogs and comments for grammar and clarity, plus incorporate Kirill's off-by-one fix] Signed-off-by: Kirill A.

a2b36ff | Hans de Goede | 12 June 2022, 14:43:25 UTC | x86/PCI: Revert "x86/PCI: Clip only host bridge windows for E820 regions" This reverts commit 4c5e242d3e93. Prior to 4c5e242d3e93 ("x86/PCI: Clip only host bridge windows for E820 regions"), E820 regions did not affect PCI host bridge windows. We only looked at E820 regions and avoided them when allocating new MMIO space. If firmware PCI bridge window and BAR assignments used E820 regions, we left them alone. After 4c5e242d3e93, we removed E820 regions from the PCI host bridge windows before looking at BARs, so firmware assignments in E820 regions looked like errors, and we moved things around to fit in the space left (if any) after removing the E820 regions. This unnecessary BAR reassignment broke several machines. Guilherme reported that Steam Deck fails to boot after 4c5e242d3e93. We clipped the window that contained most 32-bit BARs: BIOS-e820: [mem 0x00000000a0000000-0x00000000a00fffff] reserved acpi PNP0A08:00: clipped [mem 0x80000000-0xf7ffffff window] to [mem 0xa0100000-0xf7ffffff window] for e820 entry [mem 0xa0000000-0xa00fffff] which forced us to reassign all those BARs, for example, this NVMe BAR: pci 0000:00:01.2: PCI bridge to [bus 01] pci 0000:00:01.2: bridge window [mem 0x80600000-0x806fffff] pci 0000:01:00.0: BAR 0: [mem 0x80600000-0x80603fff 64bit] pci 0000:00:01.2: can't claim window [mem 0x80600000-0x806fffff]: no compatible bridge window pci 0000:01:00.0: can't claim BAR 0 [mem 0x80600000-0x80603fff 64bit]: no compatible bridge window pci 0000:00:01.2: bridge window: assigned [mem 0xa0100000-0xa01fffff] pci 0000:01:00.0: BAR 0: assigned [mem 0xa0100000-0xa0103fff 64bit] All the reassignments were successful, so the devices should have been functional at the new addresses, but some were not. Andy reported a similar failure on an Intel MID platform. Benjamin reported a similar failure on a VMWare Fusion VM. Note: this is not a clean revert; this revert keeps the later change to make the clipping dependent on a new pci_use_e820 bool, moving the checking of this bool to arch_remove_reservations().

c50f11c | Will Deacon | 10 June 2022, 15:12:27 UTC | arm64: mm: Don't invalidate FROM_DEVICE buffers at start of DMA transfer Invalidating the buffer memory in arch_sync_dma_for_device() for FROM_DEVICE transfers When using the streaming DMA API to map a buffer prior to inbound non-coherent DMA (i.e. DMA_FROM_DEVICE), we invalidate any dirty CPU cachelines so that they will not be written back during the transfer and corrupt the buffer contents written by the DMA. This, however, poses two potential problems: (1) If the DMA transfer does not write to every byte in the buffer, then the unwritten bytes will contain stale data once the transfer has completed. (2) If the buffer has a virtual alias in userspace, then stale data may be visible via this alias during the period between performing the cache invalidation and the DMA writes landing in memory. Address both of these issues by cleaning (aka writing-back) the dirty lines in arch_sync_dma_for_device(DMA_FROM_DEVICE) instead of discarding them using invalidation.

85e123c | Mikulas Patocka | 16 June 2022, 17:28:57 UTC | dm mirror log: round up region bitmap size to BITS_PER_LONG The code in dm-log rounds up bitset_size to 32 bits. It then uses find_next_zero_bit_le on the allocated region. find_next_zero_bit_le accesses the bitmap using unsigned long pointers. So, on 64-bit architectures, it may access 4 bytes beyond the allocated size. Fix this bug by rounding up bitset_size to BITS_PER_LONG. This bug was found by running the lvm2 testsuite with kasan.

1ee88de | Mikulas Patocka | 16 June 2022, 18:14:39 UTC | dm: fix narrow race for REQ_NOWAIT bios being issued despite no support Starting with the commit 63a225c9fd20, device mapper has an optimization that it will take cheaper table lock (dm_get_live_table_fast instead of dm_get_live_table) if the bio has REQ_NOWAIT. The bios with REQ_NOWAIT must not block in the target request routine, if they did, we would be blocking while holding rcu_read_lock, which is prohibited. The targets that are suitable for REQ_NOWAIT optimization (and that don't block in the map routine) have the flag DM_TARGET_NOWAIT set. Device mapper will test if all the targets and all the devices in a table support nowait (see the function dm_table_supports_nowait) and it will set or clear the QUEUE_FLAG_NOWAIT flag on its request queue according to this check. There's a test in submit_bio_noacct: "if ((bio->bi_opf & REQ_NOWAIT) && !blk_queue_nowait(q)) goto not_supported" - this will make sure that REQ_NOWAIT bios can't enter a request queue that doesn't support them. This mechanism works to prevent REQ_NOWAIT bios from reaching dm targets that don't support the REQ_NOWAIT flag (and that may block in the map routine) - except that there is a small race condition: submit_bio_noacct checks if the queue has the QUEUE_FLAG_NOWAIT without holding any locks. Immediatelly after this check, the device mapper table may be reloaded with a table that doesn't support REQ_NOWAIT (for example, if we start moving the logical volume or if we activate a snapshot). However the REQ_NOWAIT bio that already passed the check in submit_bio_noacct would be sent to device mapper, where it could be redirected to a dm target that doesn't support REQ_NOWAIT - the result is sleeping while we hold rcu_read_lock. In order to fix this race, we double-check if the target supports REQ_NOWAIT while we hold the table lock (so that the table can't change under us).

8d5459c | Jan Kara | 20 May 2022, 11:14:02 UTC | ext4: improve write performance with disabled delalloc When delayed allocation is disabled (either through mount option or because we are running low on free space), ext4_write_begin() allocates blocks with EXT4_GET_BLOCKS_IO_CREATE_EXT flag. With this flag extent merging is disabled and since ext4_write_begin() is called for each page separately, we end up with a *lot* of 1 block extents in the extent tree and following writeback is writing 1 block at a time which results in very poor write throughput (4 MB/s instead of 200 MB/s). These days when ext4_get_block_unwritten() is used only by ext4_write_begin(), ext4_page_mkwrite() and inline data conversion, we can safely allow extent merging to happen from these paths since following writeback will happen on different boundaries anyway.

However, the eventual intent is that callers should be able to ask for the assistance of the log in persisting xattr updates. This capability might not be required for /all/ callers, which means that dynamic control must work correctly. Once an xattr update has decided whether or not to use logged xattrs, it needs to stay in that mode until the end of the operation regardless of what subsequent parallel operations might do. Therefore, it is an error to continue sampling xfs_globals.larp once xfs_attr_change has made a decision about larp, and it was not correct for me to have told Allison that ->create_intent functions can sample the global log incompat feature bitfield to decide to elide a log item.

b87f023 | Petr Mladek | 15 June 2022, 16:28:05 UTC | printk: Wait for the global console lock when the system is going down There are reports that the console kthreads block the global console lock when the system is going down, for example, reboot, panic. First part of the solution was to block kthreads in these problematic system states so they stopped handling newly added messages. Second part of the solution is to wait when for the kthreads when they are actively printing. It solves the problem when a message was printed before the system entered the problematic state and the kthreads managed to step in. A busy waiting has to be used because panic() can be called in any context and in an unknown state of the scheduler. There must be a timeout because the kthread might get stuck or sleeping and never release the lock. The timeout 10s is an arbitrary value inspired by the softlockup timeout.

c323028 | Petr Mladek | 15 June 2022, 16:28:04 UTC | printk: Block console kthreads when direct printing will be required There are known situations when the console kthreads are not reliable or does not work in principle, for example, early boot, panic, shutdown. For these situations there is the direct (legacy) mode when printk() tries to get console_lock() and flush the messages directly. It works very well during the early boot when the console kthreads are not available at all. It gets more complicated in the other situations when console kthreads might be actively printing and block console_trylock() in printk(). The same problem is in the legacy code as well. Any console_lock() owner could block console_trylock() in printk(). It is solved by a trick that the current console_lock() owner is responsible for printing all pending messages. It is actually the reason why there is the risk of softlockups and why the console kthreads were introduced. The console kthreads use the same approach. They are responsible for printing the messages by definition. So that they handle the messages anytime when they are awake and see new ones. The global console_lock is available when there is nothing to do. It should work well when the problematic context is correctly detected and printk() switches to the direct mode. But it seems that it is not enough in practice. There are reports that the messages are not printed during panic() or shutdown() even though printk() tries to use the direct mode here. The problem seems to be that console kthreads become active in these situation as well. They steel the job before other CPUs are stopped. Then they are stopped in the middle of the job and block the global console_lock. First part of the solution is to block console kthreads when the system is in a problematic state and requires the direct printk() mode.

f34fdcd | Logan Gunthorpe | 08 June 2022, 16:27:46 UTC | md/raid5-ppl: Fix argument order in bio_alloc_bioset() bio_alloc_bioset() takes a block device, number of vectors, the OP flags, the GFP mask and the bio set. However when the prototype was changed, the callisite in ppl_do_flush() had the OP flags and the GFP flags reversed. This introduced some sparse error: drivers/md/raid5-ppl.c:632:57: warning: incorrect type in argument 3 (different base types) drivers/md/raid5-ppl.c:632:57: expected unsigned int opf drivers/md/raid5-ppl.c:632:57: got restricted gfp_t [usertype] drivers/md/raid5-ppl.c:633:61: warning: incorrect type in argument 4 (different base types) drivers/md/raid5-ppl.c:633:61: expected restricted gfp_t [usertype] gfp_mask drivers/md/raid5-ppl.c:633:61: got unsigned long long The sparse error introduction may not have been reported correctly by 0day due to other work that was cleaning up other sparse errors in this area.

d0a1803 | Guoqing Jiang | 07 June 2022, 02:03:56 UTC | Revert "md: don't unregister sync_thread with reconfig_mutex held" The 07reshape5intr test is broke because of below path. md_reap_sync_thread -> mddev_unlock -> md_unregister_thread(&mddev->sync_thread) And md_check_recovery is triggered by, mddev_unlock -> md_wakeup_thread(mddev->thread) then mddev->reshape_position is set to MaxSector in raid5_finish_reshape since MD_RECOVERY_INTR is cleared in md_check_recovery, which means feature_map is not set with MD_FEATURE_RESHAPE_ACTIVE and superblock's reshape_position can't be updated accordingly.

This opened the possibility for a race where IO accounting is started twice for duplicate bios. To remove the race, check the flag while holding the io->lock.
