From df05a49f7204d81ba0e29fda3d56ccb730f05d87 Mon Sep 17 00:00:00 2001 From: Kinglong Mee Date: Sat, 13 Jun 2015 10:07:00 +0800 Subject: [PATCH] nfs: Fix showing truncated fsid/dev in, /proc/net/nfsfs/volumes A truncated fsid showing from /proc/fs/nfsfs/volumes as, NV SERVER PORT DEV FSID FSC v4 c0a80881 801 0:43 34931f044c2a439b no It should be as, NV SERVER PORT DEV FSID FSC v4 c0a80881 801 0:43 34931f044c2a439b:954c5d830fa4be8c no The max buffer length for storing "%llx:%llx" format should be 16 + 1 + 16 + 1 = 34 (16 for %llx, 1 for ':', 1 for '\0'). Also, for storing "%u:%u" of MAJOR() and MINOR() should be 8 + 1 + 3 + 1 = 13 (8 for 2^24, 1 for ':', 3 for 2^8, 1 for '\0'). v2, add comments for dev/fsid buffer and use sizeof in snprintf.
