Bug#1000504: linux-image-5.15.0-1-amd64: FUSE regression in 5.15.3 affecting xdg-desktop-portal
Package: src:linux
Version: 5.15.3-1
Severity: normal
Tags: upstream
Control: affects -1 xdg-desktop-portal flatpak
Linux 5.15.3, 5.14.20 and other stable kernels are reported to have a
regression that causes Flatpak apps to freeze when using a FUSE filesystem
to load files from the host system. I can't reproduce this myself, but
it has been seen in at least Red Hat and Gentoo, so I wanted to raise
it in Debian as something to watch out for.
The regression was triggered by:
https://lore.kernel.org/all/20211115165430.669780058@linuxfoundation.org/
"fuse: fix page stealing", 712a951025c0667ff00b25afc360f74e639dfabe upstream
https://lore.kernel.org/all/CAOssrKez1mnF4rWRvWgk4LJ2iDfX8xkpMKvgprFt+-ARs83=nA@mail.gmail.com/
is a possible solution (untested - as I said, I couldn't reproduce this
myself).
Tracked elsewhere:
