fs, xattr: fix bug when removing a name not in xattr list

2012-10-18T19:35:58Z

Commit 38f38657444d ("xattr: extract simple_xattr code from tmpfs") moved some code from tmpfs but introduced a subtle bug along the way. If the name passed to simple_xattr_remove() does not exist in the list of xattrs, then it is possible to call kfree(new_xattr) when new_xattr is actually initialized to itself on the stack via uninitialized_var(). This causes a BUG() since the memory was not allocated via the slab allocator and was not bypassed through to the page allocator because it was too large. Initialize the local variable to NULL so the kfree() never takes place.

audit: set the name_len in audit_inode for parent lookups

2012-10-12T04:32:01Z

Currently, this gets set mostly by happenstance when we call into audit_inode_child. While that might be a little more efficient, it seems wrong. If the syscall ends up failing before audit_inode_child ever gets called, then you'll have an audit_names record that shows the full path but has the parent inode info attached. Fix this by passing in a parent flag when we call audit_inode that gets set to the value of LOOKUP_PARENT. We can then fix up the pathname for the audit entry correctly from the get-go. While we're at it, clean up the no-op macro for audit_inode in the !CONFIG_AUDITSYSCALL case. Signed-off-by: Jeff Layton Signed-off-by: Al Viro
