Hi,
Running llseek01 testcase as unprivileged user currently fails.
njoly@raya [syscalls/llseek]> ./llseek01
llseek01 1 TPASS : Functionality of llseek() on tmp_file successful
llseek01 2 TBROK : llseek01.c:223: Cannot reset max. file size using
setrlimit
llseek01 3 TBROK : llseek01.c:223: Remaining cases broken
This issue comes from cleanup function that tries to restore
previously altered file size limit. But this fails as unprivileged
because it cannot raise the hard limits.
The attached patch make the testcase succeed as unprivileged by
removing the offending setrlimit call.
njoly@raya [syscalls/llseek]> ./llseek01
llseek01 1 TPASS : Functionality of llseek() on tmp_file successful
Hope this helps,
Regards.
