The syslog is even scarier:<\/p>\n
\nMay 23 12:55:53 her9 kernel: cleanup[4836]: segfault at 0000000000000008 rip 00002b152350db10 rsp 00007fff855746e8 error 6\n<\/pre>\n
Yes, a segfault.  Things work better when SELinux gets disabled.
\nWithout going deeply into the reason of this incompatibility the following commands make opendkim work while SELinux is still active.<\/p>\n
This command will show you what did cause trouble today, and convert it already in to the syntax for an ‘allow’:<\/p>\n
\nausearch -m avc -ts today | audit2allow\n\n\nIf what you see is indeed only about opendkim you then can go ahead and install this:\n<\/pre>\n
\nausearch -m avc -ts today | audit2allow -M yourdesiredmodulename\nsemodule -i yourdesiredmodulename.pp\n<\/pre>\n
Things work much better then.<\/p>\n
The Centos SELinux How To<\/a> is  a helpful resource for this kind of thing.<\/p>\n","protected":false},"excerpt":{"rendered":"
