SELinux is preventing /usr/sbin/pptp from using the 'signal' accesses on a process. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that pptp should be allowed signal access on processes labeled kernel_t 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 pptpcm /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:pptp_t:s0 Target Context system_u:system_r:kernel_t:s0 Target Objects Unknown [ process ] Source pptpcm Source Path /usr/sbin/pptp Port <Unbekannt> Host (removed) Source RPM Packages pptp-1.7.2-12.fc15 Target RPM Packages Policy RPM selinux-policy-3.9.16-38.fc15 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 2.6.40.4-5.fc15.i686 #1 SMP Tue Aug 30 14:54:41 UTC 2011 i686 i686 Alert Count 1 First Seen So 18 Sep 2011 00:56:04 CEST Last Seen So 18 Sep 2011 00:56:04 CEST Local ID 2f7d5d74-d0f4-4d0a-9aa9-dd8b5601d59c Raw Audit Messages type=AVC msg=audit(1316300164.89:330): avc: denied { signal } for pid=22036 comm="pptpcm" scontext=system_u:system_r:pptp_t:s0 tcontext=system_u:system_r:kernel_t:s0 tclass=process type=SYSCALL msg=audit(1316300164.89:330): arch=i386 syscall=kill success=no exit=EACCES a0=10 a1=f a2=0 a3=92e3628 items=0 ppid=1 pid=22036 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=pptpcm exe=/usr/sbin/pptp subj=system_u:system_r:pptp_t:s0 key=(null) Hash: pptpcm,pptp_t,kernel_t,process,signal audit2allow #============= pptp_t ============== allow pptp_t kernel_t:process signal; audit2allow -R #============= pptp_t ============== allow pptp_t kernel_t:process signal;
I was trying to get NetworkManager to connect to my university's network via pptp VPN by using a dispatcher script, when this error popped up.
I guess we should allow it. We should back port the fix to RHEL6
I should add that this didn't pop up every time I tried to get the script to work, but rather once... No idea if this is more of a bug?!
Fixed in -41.fc15 policy and added to F16, RHEL6
