Subject: [9fans] linux 9p: uid & gid
Topicbox-Message-UUID: 01068612-eada-11e9-9d60-3106f5b1d025

Hi, all.

I wrote a 9p fs with help of libixp and after mounting i see strange uid =
and
gid numbers for files:

~# mount -t 9p -o trans=3Dunix,noextend q t
~# ls -l t
-rw-rw-rw- 1 4294967294 4294967294 1 Jan  1  1970 conf
-rw-rw-rw- 1 4294967294 4294967294 1 Jan  1  1970 data
-rw-rw-rw- 1 4294967294 4294967294 1 Jan  1  1970 stat

If i do mount with dfltuid and dfltgid, i get normal values:

~# mount -t 9p -o trans=3Dunix,noextend,trans=3Dunix,noextend,dfltuid=3D0=
,dfltgid=3D0 q t
~# ls -l t
-rw-rw-rw- 1 root root 1 Jan  1  1970 conf
-rw-rw-rw- 1 root root 1 Jan  1  1970 data
-rw-rw-rw- 1 root root 1 Jan  1  1970 stat

But in any case chown call to these files sends empty uid and gid strings=
 in
wstat T-message.

Is there any way to make uid & gid works as expected?

Thanks.
