## Description

In the Linux kernel, the following vulnerability has been resolved:  btrfs: reserve enough transaction items for qgroup ioctls  Currently our qgroup ioctls don't reserve any space, they just do a transaction join, which does not reserve any space, neither for the quota tree updates nor for the delayed refs generated when updating the quota tree. The quota root uses the global block reserve, which is fine most of the time since we don't expect a lot of updates to the quota root, or to be too close to -ENOSPC such that other critical metadata updates need to resort to the global reserve.  However this is not optimal, as not reserving proper space may result in a transaction abort due to not reserving space for delayed refs and then abusing the use of the global block reserve.  For example, the following reproducer (which is unlikely to model any real world use case, but just to illustrate the problem), triggers such a transaction abort due to -ENOSPC when running delayed refs:    $ cat test.sh   #!/bin/bash    DEV=/dev/nullb0   MNT=/mnt/nullb0    umount $DEV &> /dev/null   # Limit device to 1G so that it's much faster to reproduce the issue.   mkfs.btrfs -f -b 1G $DEV   mount -o commit=600 $DEV $MNT    fallocate -l 800M $MNT/filler   btrfs quota enable $MNT    for ((i = 1; i <= 400000; i++)); do       btrfs qgroup create 1/$i $MNT   done    umount $MNT  When running this, we can see in dmesg/syslog that a transaction abort happened:    [436.490] BTRFS error (device nullb0): failed to run delayed ref for logical 30408704 num_bytes 16384 type 176 action 1 ref_mod 1: -28   [436.493] ------------[ cut here ]------------   [436.494] BTRFS: Transaction aborted (error -28)   [436.495] WARNING: fs/btrfs/extent-tree.c:2247 at btrfs_run_delayed_refs+0xd9/0x110 [btrfs], CPU#4: umount/2495372   [436.497] Modules linked in: btrfs loop (...)
