• Type: Bug
• Resolution: Fixed

Description

The patch from bugzilla ticket 22766 added the following code:

diff --git a/lustre/utils/liblustreapi.c b/lustre/utils/liblustreapi.c
index 1e88a51..72818c8 100644
--- a/lustre/utils/liblustreapi.c
+++ b/lustre/utils/liblustreapi.c
@@ -1566,6 +1566,8 @@ int llapi_file_get_stripe(const char *path, struct lov_user_md *lum)
         int fd, rc = 0;
 
         fname = strrchr(path, '/');
+        if (strlen(fname) + 1 < sizeof(struct lov_user_md))
+                return ENAMETOOLONG;

This check does not make any sense and causes llapi_file_get_stripe() to fail with ENAMETOOLONG without any obvious reasons.
