From e64b13f62782f5e495c085e1c06e48224545617f Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Fri, 18 Dec 2009 16:28:05 -0500 Subject: [PATCH] SUNRPC: Fix up an error return value in gss_import_sec_context_kerberos() commit 14ace024b1e16d2bb9445c8387494fbbd820a738 upstream. If the context allocation fails, the function currently returns a random error code, since the variable 'p' still points to a valid memory location. Ensure that it returns ENOMEM...
