Package: linux-image-amd64
Version: 6.12.43-1
NFSv4.2 reports "Operation Not Supported" on getxattr calls.
The following is with the same NFS backend, and same mount options. The
NFS server reports name: "Linux NFSv4.2 [an identifier]" under
/proc/fs/nfsd/clients/*/info for both clients.
Bookworm:
# touch testfile
# setfattr -h -n user.test -v yes testfile
# getfattr -h -n user.test testfile
# file: testfile
user.test="yes"
Trixie:
# setfattr -h -n user.test -v yes testfile
setfattr: testfile: Operation not supported
# getfattr -h -n user.test testfile
testfile: user.test: Operation not supported
There seems to be a regression in set/getxattr handling in 6.12 and other
branches. This may be helpful:
