Attachment has gone missing. Which version of kernel-headers are you using? (If this still is an issue)
Comment 2 Simon McVittie 2011-01-19 07:08:19 UTC
CAP_AUDIT_WRITE is indeed used without a guard other than HAVE_LIBAUDIT. libaudit support is auto-detected.

I'd personally be inclined to make configure.in bail out if you enable libaudit support and your kernel headers are too old for CAP_AUDIT_WRITE.

This can be worked around with "./configure --disable-libaudit" so I'm reducing the priority/severity.
Comment 3 Simon McVittie 2015-02-19 11:40:32 UTC
       CAP_AUDIT_WRITE (since Linux 2.6.11)

I don't think we (should) support Linux systems that old any more.

Workaround, if you are using outdated kernel headers: --disable-libaudit.
