I'm running Debian Unstable booting with file-rc, and there are several
system daemons that have screwy SigBlk masks, of which sshd is one. They
are listed in the attached "commands" file.
You can get the data for a similar report on your own machine by running
the following commands (as root):
grep SigBlk /proc/*/status | grep -v 0000000000000000 > commands
for x in $(grep SigBlk /proc/*/status | grep -v 000000000000 | \
sed -e 's@/proc/\(.*\)/status.*$@\1@g'); do
echo -n "$x: "
cat /proc/$x/cmdline
echo
done >> commands
(After running this, I cleaned things up a bit in vim to better organize
the report.)
Maybe this will help debug the root of the problem, though if sshd is
inheriting a screwy SigBlk mask, it should be patched to defensively fix
the SigBlk mask.
