From 4303ef19c6e6d16ea845c04b02b9cf086bcb8ed7 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 11 Jun 2010 17:30:05 +0100 Subject: [PATCH] KEYS: Propagate error code instead of returning -EINVAL This is from a Smatch check I'm writing. strncpy_from_user() returns -EFAULT on error so the first change just silences a warning but doesn't change how the code works. The other change is a bug fix because install_thread_keyring_to_cred() can return a variety of errors such as -EINVAL, -EEXIST, -ENOMEM or -EKEYREVOKED.
