rpc.idmapd runs out of file descriptors

rpc.idmapd runs out of file descriptors

[Sergio Gelato]

[-- Attachment #1: Type: text/plain, Size: 1430 bytes --]

Observed on Debian 12 (nfs-utils 2.6.2):

May 28 09:40:25 HOSTNAME rpc.idmapd[3602614]: dirscancb: scandir(/run/rpc_pipefs/nfs): Too many open files
[repeated multiple times]

Investigation with lsof on one of the affected systems shows that file desciptors are not being closed:

[...]
rpc.idmap 675 root  126r      DIR               0,40        0      10813 /run/rpc_pipefs/nfs/clnt11e6 (deleted)
rpc.idmap 675 root  127u     FIFO               0,40      0t0      10817 /run/rpc_pipefs/nfs/clnt11e6/idmap (deleted)
rpc.idmap 675 root  128r      DIR               0,40        0      10834 /run/rpc_pipefs/nfs/clnt11ef (deleted)
rpc.idmap 675 root  129u     FIFO               0,40      0t0      10838 /run/rpc_pipefs/nfs/clnt11ef/idmap (deleted)
rpc.idmap 675 root  130r      DIR               0,40        0      10855 /run/rpc_pipefs/nfs/clnt11f8 (deleted)
rpc.idmap 675 root  131u     FIFO               0,40      0t0      10859 /run/rpc_pipefs/nfs/clnt11f8/idmap (deleted)

Raising the verbosity level to 3 results in no "Stale client:" lines.
strace shows no close() calls other than for the /run/rpc_pipefs/nfs directory.

I believe this is because in dirscancb() the loop is exited prematurely
the first time nfsopen() returns -1, preventing later entries in the queue
from being reaped. I've tested the patch below, which seems indeed to cure
the problem. The bug appears to be still unfixed in the current master branch.

Subject: rpc.idmapd: nfsopen() failures should not be fatal

dirscancb() loops over all clnt* subdirectories of /run/rpc_pipefs/nfs/.
Some of these directories contain /idmap files, others don't. nfsopen()
returns -1 for the latter; we then want to skip the directory, not abort
the entire scan.

It probably fell through the cracks.  It is always good to mail
nfs-utils patches to SteveD as well as the list.  You've done that now
so hopefully he will pick it up.

I think that patch looks good and sensible.

It did because it was not in the appropriate format... The patch
was an attachment, not in-line, no  Signed-off-by: line and
the patch was not create by git format-patch command (which
adds PATCH in the subject line).

I have filters that look for things like that and I just
didn't see it...

I see no mention of formatting requirements at
https://www.linux-nfs.org/wiki/index.php/Reporting_bugs
(not even by reference to the Linux kernel tree).

Thank you all for looking into it. Steve, do you need to have it
re-submitted in a git format-patch format? At least a Signed-off-by
line by Sergio would be needed in my understanding.

I guess otherwise we can use soemthing like the following though a
Signed-off-by is probably not right here, or is it enough if I say
Reported-by: and Patch-originally-by: although the later is not an
official kernel doc mentioned tag?

And then one seems to be able to do so many mistakes around one patch.
Here is an improved version (v2), fixing a typo in the Link reference
and using a Closes: tag after the Reported-by:

This now should be better than the previous one.

I don't object to (nor do I require) your adding a

Signed-off-by: Sergio Gelato <Sergio.Gelato@astro.su.se>

(I am indeed the author of the patch, and it's too trivial to be
copyrightable anyway).

I guess Neil's comment earlier can be taken as equivalent to an Acked-by:. 

By the way, I have wondered whether to change the other two instances of
"goto out" in dirscancb() as well. For the first one (calloc() failure)
I think this would be counterproductive (one is likely to get the same
error on all subsequent iterations), the second (directory open()) is
more debatable (but failure of the directory open() should be so rare
that it doesn't matter).
