Package: src:linux
Version: 5.9.1-1
Severity: minor
Dear Maintainer,
The sunrpc.transports sysctl looks emtpy when directly queried with sysctl,
but a closer inspection of /proc/sys/sunrpc/transports reveals a list of null
bytes. Even weirder, sysctl -a does produce a different set of random(?)
characters each time.
I would expect an output such as:
sunrpc.transports = tcp 1048576
sunrpc.transports = udp 32768
instead of this weirdness.
$ /sbin/sysctl sunrpc.transports | cat -A ; od -c /proc/sys/sunrpc/transports ; /sbin/sysctl -a 2>/dev/null | grep -a sunrpc.transports
sunrpc.transports = $
0000000 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0
0000020 \0 \0 \0 \0 \0 \0
0000026
sunrpc.transports = �]�
$ /sbin/sysctl -a 2>/dev/null | grep -a sunrpc.transports
sunrpc.transports = ��
$ /sbin/sysctl -a 2>/dev/null | grep -a sunrpc.transports
sunrpc.transports = �vo�
Last week I updated this system to Debian testing (from stable).

I think this was fixed in c09f56b8f68d ("net/sunrpc: Fix return value
for sysctl sunrpc.transports") in v5.10-rc1 and was backported to
5.9.5, so in included in 5.9.6-1.
