-Subject: [PATCH] 9pfs: use g_malloc0 to allocate space for xattr
-
-9p back-end first queries the size of an extended attribute,
-allocates space for it via g_malloc() and then retrieves its
-value into allocated buffer. Race between querying attribute
-size and retrieving its could lead to memory bytes disclosure.
-Use g_malloc0() to avoid it.
