From 8e158aa65577b96494eaa94c4983eed1449116dc Mon Sep 17 00:00:00 2001 From: Steve Dickson Date: Tue, 15 Jul 2008 14:43:00 -0400 Subject: [PATCH] It appears that a recent glibc update now enforces the requirement for a mode parameter for open calls with the O_CREAT flag set. nfs-utils support code defines a function xflock used by exportfs and mountd that calls open with O_CREAT but no mode parameter. This causes exportfs and mountd to dump core, with the error message: *** invalid open64 call: O_CREAT without mode ***:rpc.mountd terminated Signed-off-by: Steve Dickson --- support/nfs/xio.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/support/nfs/xio.c b/support/nfs/xio.c index 0453ca7..f21f5f0 100644 --- a/support/nfs/xio.c +++ b/support/nfs/xio.c @@ -54,13 +54,19 @@ xflock(char *fname, char *type) { struct sigaction sa, oldsa; int readonly = !strcmp(type, "r"); + mode_t mode = (S_IRUSR|S_IWUSR|S_IRGRP|S_IROTH); struct flock fl = { readonly?
