Description of problem: In i386, if I try to 'getfilecon' a file which SELinux prohibits access, python dies with 'segfault': [testuser/user_r/SystemLow@rhel5 ~]$ id uid=501(testuser) gid=501(testuser) groups=501(testuser) context=testuser_u:user_r:user_t:SystemLow-SystemHigh [testuser/user_r/SystemLow@rhel5 ~]$ python Python 2.4.3 (#1, Dec 11 2006, 11:38:52) [GCC 4.1.1 20061130 (Red Hat 4.1.1-43)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import selinux >>> selinux.getfilecon('/dev/usb/lp0') Segmentation fault [testuser/user_r/SystemLow@rhel5 ~]$ python Python 2.4.3 (#1, Dec 11 2006, 11:38:52) [GCC 4.1.1 20061130 (Red Hat 4.1.1-43)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import selinux >>> selinux.getfilecon('/root/.ssh') Segmentation fault [testuser/user_r/SystemLow@rhel5 ~]$ == Relevant(?) audit messages: == type=SYSCALL msg=audit(1173896641.831:624): arch=40000003 syscall=229 success=no exit=-13 a0=b7ec78a4 a1=4612b3 a2=9d16498 a3=ff items=1 ppid=14687 pid=14716 auid=501 uid=501 gid=501 euid=501 suid=501 fsuid=501 egid=501 sgid=501 fsgid=501 tty=pts0 comm="python" exe="/usr/bin/python" subj=testuser_u:user_r:user_t:s0-s15:c0.c1023 key=(null) type=CWD msg=audit(1173896641.831:624): cwd="/home/testuser" type=PATH msg=audit(1173896641.831:624): item=0 name="/dev/usb/lp0" inode=5662 dev=00:10 mode=020660 ouid=0 ogid=7 rdev=b4:00 obj=system_u:object_r:printer_device_t:s0 Version-Release number of selected component (if applicable): libselinux-python-1.33.4-2.el5 How reproducible: always Steps to Reproduce: See Description Actual results: Segfault Expected results: something like [-1, ''] Additional info: The strange thing is that I could only reproduce this on i386 x86_64 and ppc64 seems fine: [testuser/user_r/SystemLow@zaphod ~]$ python Python 2.4.3 (#1, Dec 11 2006, 11:40:12) [GCC 4.1.1 20061130 (Red Hat 4.1.1-43)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import selinux >>> selinux.getfilecon('/root/.ssh') [-1, ''] >>> Although i386 is not in the LSPP evaluation, this bug is causing impact on test development I can to debug further if the relevant debuginfo files are made available
