From b9cb946fac3288e7a35571525ef09946e2ba6d7f Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Fri, 14 May 2010 15:33:36 +0400 Subject: [PATCH] NFSD: don't report compiled-out versions as present commit 15ddb4aec54422ead137b03ea4e9b3f5db3f7cc2 upstream. The /proc/fs/nfsd/versions file calls nfsd_vers() to check whether the particular nfsd version is present/available. The problem is that once I turn off e.g. NFSD-V4 this call returns -1 which is true from the callers POV which is wrong. The proposal is to report false in that case. The bug has existed since 6658d3a7bbfd1768 "[PATCH] knfsd: remove nfsd_versbits as intermediate storage for desired versions". Signed-off-by: Pavel Emelyanov Acked-by: NeilBrown Signed-off-by: J.
