Title:
"btrfs subvolume list" sporadically segfaults with linux-
image-5.4.0-52-generic
Status in linux package in Ubuntu:
Fix Committed
Bug description:
On a BTRFS volume with a lot of subvolumes, I get sporadic segfaults
on "btrfs subvolume list", about 1/3 of the time. This is on Ubuntu
20.04.
linux-image-5.4.0-48-generic does not experience those segfaults.
On #btrfs on freenode, it was pointed out that 5.4.0-52.57 seems to
have a regression but not the fix for it committed. To quote from the
IRC message:
> 5.4.0-52.57 has a regression (a48b73eca4ce btrfs: fix potential
deadlock in the search ioctl) and not the fix (1c78544eaa46 btrfs: fix
wrong address when faulting in pages in the search ioctl)
