Title:
memlock is not set
Status in systemd package in Ubuntu:
Confirmed
Status in systemd package in Debian:
New
Bug description:
I discovered this in relation to jack, which installs
/etc/security/limits.d/audio.conf, containing:
@audio - rtprio 95
@audio - memlock unlimited
For a user in the audio group:
$ulimit -l -r
max locked memory (kbytes, -l) 65536
real-time priority (-r) 95
So jack (run as user via qjackctl) reports:
ERROR: Cannot lock down 82280346 byte memory area (Cannot allocate
memory)
but does not report that it cannot set real-time priority, which it
does if run by a user not in the audio group.
I also tried putting the line in /etc/security/limits.conf, and trying
a number rather than "unlimited", but it didn't help.
