I saw the exact same thing. Same behaviour. Dell Latitude D830. Used the suggestion in the troubleshooter and it worked. grep wpa_supplicant /var/log/audit/audit.log | audit2allow -M mypol semodule -i mypol.pp *** This bug has been marked as a duplicate of bug 684415 *** |
Description of problem: Get SELinux Alert after waking up laptop from suspend mode that "the source process: /usr/sbin/wpa_supplicant" attempted this access: sys_module Version-Release number of selected component (if applicable): Fedora 14 How reproducible: Wake up laptop from suspend mode. Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info: New Note 5 SELinux is preventing /usr/sbin/wpa_supplicant from using the sys_module capability. ***** Plugin sys_module (99.5 confidence) suggests ************************* If you do not believe that /usr/sbin/wpa_supplicant should be attempting to modify the kernel by loading a kernel module. Then a process might be attempting to hack into your system. Do contact your security administrator and report this issue. ***** Plugin catchall (1.49 confidence) suggests *************************** If you believe that wpa_supplicant should have the sys_module capability by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # grep wpa_supplicant /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:NetworkManager_t:s0-s0:c0.c1023 Target Context system_u:system_r:NetworkManager_t:s0-s0:c0.c1023 Target Objects Unknown [ capability ] Source wpa_supplicant Source Path /usr/sbin/wpa_supplicant Port <Unknown> Host (removed) Source RPM Packages wpa_supplicant-0.6.8-10.fc14 Target RPM Packages Policy RPM selinux-policy-3.9.7-37.fc14 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 2.6.35.12-88.fc14.x86_64 #1 SMP Thu Mar 31 21:21:57 UTC 2011 x86_64 x86_64 Alert Count 5 First Seen Mon 11 Apr 2011 08:20:36 PM EDT Last Seen Tue 12 Apr 2011 07:40:10 PM EDT Local ID fd00b79a-cb06-45cd-9acc-e458fbbd88af Raw Audit Messages type=AVC msg=audit(1302651610.727:32): avc: denied { sys_module } for pid=1406 comm="wpa_supplicant" capability=16 scontext=system_u:system_r:NetworkManager_t:s0-s0:c0.c1023 tcontext=system_u:system_r:NetworkManager_t:s0-s0:c0.c1023 tclass=capability type=SYSCALL msg=audit(1302651610.727:32): arch=x86_64 syscall=ioctl success=no exit=ENODEV a0=8 a1=8933 a2=7fff7ec0c8b0 a3=b3f1ebb1950f99a8 items=0 ppid=1 pid=1406 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=wpa_supplicant exe=/usr/sbin/wpa_supplicant subj=system_u:system_r:NetworkManager_t:s0-s0:c0.c1023 key=(null) Hash: wpa_supplicant,NetworkManager_t,NetworkManager_t,capability,sys_module audit2allow #============= NetworkManager_t ============== allow NetworkManager_t self:capability sys_module; audit2allow -R #============= NetworkManager_t ============== allow NetworkManager_t self:capability sys_module;
