From 41a71b47f75a52f50ad2754cce679407ebade767 Mon Sep 17 00:00:00 2001 From: Kotresh HR Date: Wed, 7 Dec 2016 07:36:19 -0500 Subject: glusterd/geo-rep: Fix glusterd crash Problem: glusterd crashes when geo-rep mountbroker setup is created if the slave user length is more than 8 characters. Cause: _POSIX_LOGIN_NAME_MAX is used which is 9 including NULL byte. Analysis: While the man page says it sufficient for portability, but acutally it's not. Linux allows the creation of username upto 32 characters by default where the max length is 256. And NetBSD's max is 17. Linux: #getconf LOGIN_NAME_MAX 256 NetBSD: #getconf LOGIN_NAME_MAX 17 Fix: Use LOGIN_NAME_MAX instead of _POSIX_LOGIN_NAME_MAX Change-Id: I26b7230433ecbbed6e6914ed39221a478c0266a8 BUG: 1368138 Signed-off-by: Kotresh HR Reviewed-on: http://review.gluster.org/16053 Smoke: Gluster Build System NetBSD-regression: NetBSD Build System CentOS-regression: Gluster Build System Reviewed-by: Aravinda VK Reviewed-by: Atin Mukherjee --- libglusterfs/src/compat.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'libglusterfs/src') diff --git a/libglusterfs/src/compat.h b/libglusterfs/src/compat.h index 69adfbcd7fe..ea722028eb5 100644 --- a/libglusterfs/src/compat.h +++ b/libglusterfs/src/compat.h @@ -158,6 +158,10 @@ enum { #define s6_addr32 __u6_addr.__u6_addr32 #endif +#ifndef LOGIN_NAME_MAX +#define LOGIN_NAME_MAX 256 +#endif + /* Posix dictates NAME_MAX to be used */ # ifndef NAME_MAX # ifdef MAXNAMLEN -- cgit
