Subject: [ 23/94] KEYS: Use the compat keyctl() syscall wrapper on Sparc64 for Sparc32 compat
Date: Sun, 27 May 2012 10:04:46 +0900 [thread overview]
Message-ID: <20120527010427.030988575@linuxfoundation.org> (raw)
In-Reply-To: <20120527010332.GA11170@kroah.com>
3.3-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Howells <dhowells@redhat.com>
commit 45de6767dc51358a188f75dc4ad9dfddb7fb9480 upstream.
Use the 32-bit compat keyctl() syscall wrapper on Sparc64 for Sparc32 binary
compatibility.
Without this, keyctl(KEYCTL_INSTANTIATE_IOV) is liable to malfunction as it
uses an iovec array read from userspace - though the kernel should survive this
as it checks pointers and sizes anyway.
I think all the other keyctl() function should just work, provided (a) the top
32-bits of each 64-bit argument register are cleared prior to invoking the
syscall routine, and the 32-bit address space is right at the 0-end of the
64-bit address space. Most of the arguments are 32-bit anyway, and so for
those clearing is not required.
