Fwd: Bug#765410: ulimit broken as root if it fails once [origin: goswin-v-b@xxxxxx]


the following has been reported in Debian at
http://bugs.debian.org/765410 and I can reprodcue it with 4.3.10,
4.3.17, 5.0.6 and 5.0.7.

The issue seems to only appear if ulimit is run as root user. I was
not able to reproduce it as non-root user. (I was also unable to
reproduce it on any of Debian's kfreebsd-* architectures, so it may be
a linux-only issue, too.)

Package: zsh
Version: 5.0.5-2
Severity: normal

root@frosties:~# ulimit -n 1000   
root@frosties:~# ulimit -n 10000000
limit: setrlimit failed: operation not permitted
root@frosties:~# ulimit -n 1000   
limit: setrlimit failed: operation not permitted

Once setting a limit with ulimit fails all further attempts to set a
limit will also fail. But only in zsh. Works fine in bash.
