Subject: [PATCH] Resolve denial while changing password
Date: Mon, 11 Mar 2019 16:02:29 +0000 [thread overview]
Message-ID: <20190311160147.17642-1-dsugar@tresys.com> (raw)
I'm seeing the following denials reading /proc/sys/crypto/fips_enabled
and sending message for logging. This resolves those denials.
type=AVC msg=audit(1552222811.419:470): avc: denied { search } for pid=7739 comm="passwd" name="crypto" dev="proc" ino=2253 scontext=sysadm_u:sysadm_r:passwd_t:s0-s0:c0.c1023 tcontext=system_u:object_r:sysctl_crypto_t:s0 tclass=dir permissive=1
