* Fix mkdtemp() umask issuefche2008-01-021-0/+2
| | | | | | | | | | | | | | | | | | | | | Even though the mkdtemp() man page indicates that the directory will be created with always 0700 permissions, it is actually affected by the process's umask. So, if you run stap with an unusual umask it can end up creating the temp dir with permissions that staprun can't handle e.g.: $> rpm -q systemtap systemtap-0.6-1.fc9 $> umask 0122 $> stap -e 'probe begin { println("foo") exit() }' ERROR: Error opening '/tmp/stapV4pBIb/stap_725b9bc541cef2618a5ccbc58bb64d15_287.ko': Permission denied Obvious solution is to briefly set the umask to zero in stap so as to ensure 0700 permissions.
