[LTP] Change to runltp. Make tmp
directory writable for user nobody
04/04/07 08:06 PM
Please respond to
[EMAIL PROTECTED]
Folks,
Short version -
Changed the way runltp makes the temp directory that is uses
for
running test. Plus some spacing, indent changes. This is a patch that
was tested and applied against the 20070228 version of ltp-full.
Long version -
This was the error scenario I hit. When running ltp in the
following manor:
./runltp -p -d /mnt/testarea -l /mnt/testarea/syscalls.log -o
/mnt/testarea/syscalls.run.log -f syscalls
The below list of tests would fail, all in the same way. With
a
errno = 13: Permission denied. What all these tests have in common is
that in the setup function of the test it will switch to user nobody
before calling the tmp_tstdir function (as it should).
When runltp is started, it cases the args when it sees -d
It does the following.
d) # append $$ to TMP, as it is recursively
# removed at end of script.
TMPBASE=$OPTARG
TMP="${TMPBASE}/ltp-$$"
export TMPDIR="$TMP";;
So in my case the directory at this point is
/mnt/testarea/ltp-pid.
Further down in runltp it makes the directory /mnt/testarea/ltp-pid as
user root.
mkdir -p $TMP || \
{
echo "FATAL: Unable to make temporary directory $TMP"
exit 1
}
So in test cases that changes userid, user nobody does not
have the
correct permission to make additional directories under
/mnt/testarea/ltp-pid/foo
