Description Horst H. von Brand 2010-07-30 14:22:04 UTC

SELinux is preventing /usr/sbin/sendmail.sendmail "getattr" access on

Detailed Description:

SELinux denied access requested by sendmail. It is not expected that this access
is required by sendmail and this access may signal an intrusion attempt. It is
also possible that the specific version or configuration of the application is
causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug

Comment 1 Horst H. von Brand 2010-07-30 14:22:47 UTC
I have a locally generated sendmail.cf

Comment 2 Horst H. von Brand 2010-08-02 19:54:19 UTC
It seems quite nonsensical that sendmail can't stat(2) or similar its main configuration file...

BTW, what the heck is getattr? The man pages know nothing of such a system call...

It will be fixed in the next F14 selinux-policy release.

'getattr' is SELinux permission which gets attributes for object such as access mode (for example - stat(), some ioctls)

From AVC message we know that syscall=4

# ausyscall 4
