Hi,

I'm running Fedora 35, and I'm trying to replicate a Fedora 36 root
snapshot from one Btrfs file system to another, but it fails.

This is what I see on CLI (with verbose logging)

set_xattr etc/NetworkManager/dispatcher.d - name=security.selinux
data_len=56 data=system_u:object_r:NetworkManager_dispatcher_script_t:s0
ERROR: lsetxattr etc/NetworkManager/dispatcher.d
security.selinux=system_u:object_r:NetworkManager_dispatcher_script_t:s0
failed: Invalid argument

This is the AVC error:

[25325.074972] audit[23509]: AVC avc:  denied  { mac_admin } for
pid=23509 comm="btrfs" capability=33
scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
tclass=capability2 permissive=0
[25325.075188] audit: SELINUX_ERR op=setxattr
invalid_context="system_u:object_r:NetworkManager_dispatcher_script_t:s0"

I think what's going on is, Fedora 35's SELinux is preventing `btrfs
receive` from setting a label it doesn't know. If so, is this
definitely the correct behavior? Or is there something `btrfs receive`
could do to allow setting this unfamiliar label anyway?

I filed a btrfs-progs bug, feel free to answer there (or here)

Thanks,
