Subject: [PATCH 1/3] gssd: fix strncmp bug causing client removals
Date: Thu, 19 Sep 2013 16:57:17 -0400	[thread overview]
Message-ID: <1379624239-31199-2-git-send-email-bfields@redhat.com> (raw)
In-Reply-To: <1379624239-31199-1-git-send-email-bfields@redhat.com>

From: root <root@pip4.fieldses.org>

Both dirname and pdir are null-terminated strings, so there's no reason
I can see for the strncmp.

And this gives the wrong result when comparing the "nfsd" and "nfsd4_cb"
directories!  The results were callback clients being removed
immediately after creation, when lack of a client with the corresponding
name under "nfsd" lead gssd to believe it had disappeared from
"nfsd4_cb".
