[PATCH] tpm: Define TPM2_SPACE_BUFFER_SIZE to replace the use of PAGE_SIZE

by Jarkko Sakkinen

The size of the buffers for storing context's and sessions can vary from arch to arch as PAGE_SIZE can be anything between 4 kB and 256 kB (the maximum for PPC64). Define a fixed buffer size set to 16 kB. This should be enough for most use with three handles (that is how many we allow at the moment).

These preallocated extents have, and must have, the same size that extents from the data block group being relocated have. Later before we start the relocation stage that updates pointers (bytenr field of file extent items) to point to the the new extents, we trigger writeback for the data relocation inode. The expectation is that writeback will write the pages to the previously preallocated extents, that it follows the NOCOW path. That is generally the case, however, if a scrub is running it may have turned the block group that contains those extents into RO mode, in which case writeback falls back to the COW path. However in the COW path instead of allocating exactly one extent with the expected size, the allocator may end up allocating several smaller extents due to free space fragmentation - because we tell it at cow_file_range() that the minimum allocation size can match the filesystem's sector size. This later breaks the relocation's expectation that an extent associated to a file extent item in the data relocation inode has the same size as the respective extent pointed by a file extent item in another tree - in this case the extent to which the relocation inode poins to is smaller, causing relocation.c:get_new_location() to return -EINVAL. For example, if we are relocating a data block group X that has a logical address of X and the block group has an extent allocated at the logical address X + 128KiB with a size of 64KiB: 1) At prealloc_file_extent_cluster() we allocate an extent for the data relocation inode with a size of 64KiB and associate it to the file offset 128KiB (X + 128KiB - X) of the data relocation inode. This preallocated extent was allocated at block group Z; 2) A scrub running in parallel turns block group Z into RO mode and starts scrubing its extents; 3) Relocation triggers writeback for the data relocation inode; 4) When running delalloc (btrfs_run_delalloc_range()), we try first the NOCOW path because the data relocation inode has BTRFS_INODE_PREALLOC set in its flags. However, because block group Z is in RO mode, the NOCOW path (run_delalloc_nocow()) falls back into the COW path, by calling cow_file_range(); 5) At cow_file_range(), in the first iteration of the while loop we call btrfs_reserve_extent() to allocate a 64KiB extent and pass it a minimum allocation size of 4KiB (fs_info->sectorsize). Due to free space fragmentation, btrfs_reserve_extent() ends up allocating two extents of 32KiB each, each one on a different iteration of that while loop; 6) Writeback of the data relocation inode completes; 7) Relocation proceeds and ends up at relocation.c:replace_file_extents(), with a leaf which has a file extent item that points to the data extent from block group X, that has a logical address (bytenr) of X + 128KiB and a size of 64KiB. Then it calls get_new_location(), which does a lookup in the data relocation tree for a file extent item starting at offset 128KiB (X + 128KiB - X) and belonging to the data relocation inode. It finds a corresponding file extent item, however that item points to an extent that has a size of 32KiB, which doesn't match the expected size of 64KiB, resuling in -EINVAL being returned from this function and propagated up to __btrfs_cow_block(), which aborts the current transaction. To fix this make sure that at cow_file_range() when we call the allocator we pass it a minimum allocation size corresponding the desired extent size if the inode belongs to the data relocation tree, otherwise pass it the filesystem's sector size as the minimum allocation size.

FAILED: patch "[PATCH] btrfs: fix race between block group removal and block group" failed to apply to 5.7-stable tree

The patch below does not apply to the 5.7-stable tree.

When this happens we end up failing the block group creation with an error -EEXIST since we attempt to insert a duplicate block group item key in the extent tree. That results in a transaction abort. The race happens like this: 1) Task A is doing a fitrim, and at btrfs_trim_block_group() it freezes block group X with btrfs_freeze_block_group() (until very recently that was named btrfs_get_block_group_trimming()); 2) Task B starts removing block group X, either because it's now unused or due to relocation for example. So at btrfs_remove_block_group(), while holding the chunk mutex and the block group's lock, it sets the 'removed' flag of the block group and it sets the local variable 'remove_em' to false, because the block group is currently frozen (its 'frozen' counter is > 0, until very recently this counter was named 'trimming'); 3) Task B unlocks the block group and the chunk mutex; 4) Task A is done trimming the block group and unfreezes the block group by calling btrfs_unfreeze_block_group() (until very recently this was named btrfs_put_block_group_trimming()). In this function we lock the block group and set the local variable 'cleanup' to true because we were able to decrement the block group's 'frozen' counter down to 0 and the flag 'removed' is set in the block group. Since 'cleanup' is set to true, it locks the chunk mutex and removes the extent mapping representing the block group from the mapping tree; 5) Task C allocates a new block group Y and it picks up the logical address that block group X had as the logical address for Y, because X was the block group with the highest logical address and now the second block group with the highest logical address, the last in the fs mapping tree, ends at an offset corresponding to block group X's logical address (this logical address selection is done at volumes.c:find_next_chunk()). At this point the new block group Y does not have yet its item added to the extent tree (nor the corresponding device extent items and chunk item in the device and chunk trees). The new group Y is added to the list of pending block groups in the transaction handle; 6) Before task B proceeds to removing the block group item for block group X from the extent tree, which has a key matching: (X logical offset, BTRFS_BLOCK_GROUP_ITEM_KEY, length) task C while ending its transaction handle calls btrfs_create_pending_block_groups(), which finds block group Y and tries to insert the block group item for Y into the exten tree, which fails with -EEXIST since logical offset is the same that X had and task B hasn't yet deleted the key from the extent tree. This failure results in a transaction abort, producing a stack like the following: ------------[ cut here ]------------ BTRFS: Transaction aborted (error -17) WARNING: CPU: 2 PID: 19736 at fs/btrfs/block-group.c:2074 btrfs_create_pending_block_groups+0x1eb/0x260 [btrfs] Modules linked in: btrfs blake2b_generic xor raid6_pq (...)

There is a second bug where if removing the free space tree entries (the call to remove_block_group_free_space()) fails we end up jumping to the 'out_put_group' label but end up decrementing the reference count only once, when we should have done it twice, since we have already removed the block group from the block group cache rbtree. This happens because the reference count decrement for the rbtree reference happens after attempting to remove the free space tree entries, which is far away from the place where we remove the block group from the rbtree. To make things less error prone, decrement the reference count for the rbtree immediately after removing the block group from it. This also eleminates the need for two different exit labels on error, renaming 'out_put_label' to just 'out' and removing the old 'out'.

[PATCH] Drivers: hv: Change flag to write log level in panic msg to false

by Joseph Salisbury

When the kernel panics, one page worth of kmsg data is written to an allocated page. The Hypervisor is notified of the page address trough the MSR. This panic information is collected on the host. Since we are only collecting one page of data, the full panic message may not be collected. Each line of the panic message is prefixed with the log level of that particular message in the form <N>, where N is the log level. The typical 4 Kbytes contains anywhere from 50 to 100 lines with that log level prefix. hv_dmsg_dump() makes a call to kmsg_dump_get_buffer(). The second argument in the call is a bool described as: ‘@syslog: include the “<4>” Prefixes’. With this change, we will not write the log level to the allocated page. This will provide additional room in the allocated page for more informative panic information. Requesting in stable kernels, since many kernels running in production are stable releases.
