[Libguestfs] [PATCH] fuse: clear stat structs (RHBZ#660687).

Not all the fields of struct stat are actually filled by us. This caused rubbish to appear in the microseconds fields, which were then used as base when changing atime/ctime (with e.g. touch), triggering EINVAL by futimens/utimensat when those rubbish values were out of the range allowed for microseconds. --- src/fuse.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/src/fuse.c b/src/fuse.c index 288c02a..dd4f139 100644 --- a/src/fuse.c +++ b/src/fuse.c @@ -175,6 +175,7 @@ mount_local_readdir (const char *path, void *buf, fuse_fill_dir_t filler, if (ss->val[i].ino >= 0) { struct stat statbuf; + memset (&statbuf, 0, sizeof statbuf); statbuf.st_dev = ss->val[i].dev; statbuf.st_ino = ss->val[i].ino; statbuf.st_mode = ss->val[i].mode; @@ -255,6 +256,7 @@ mount_local_getattr (const char *path, struct stat *statbuf) if (r == NULL) RETURN_ERRNO; + memset (statbuf, 0, sizeof *statbuf); statbuf->st_dev = r->dev; statbuf->st_ino = r->ino; statbuf->st_mode = r->mode; -- 1.8.3.1
