+Subject: pipe: iovec: Fix memory corruption when retrying atomic copy
+ as non-atomic
+
+From: Ben Hutchings <ben@decadent.org.uk>
+
+pipe_iov_copy_{from,to}_user() may be tried twice with the same iovec,
+the first time atomically and the second time not. The second attempt
+needs to continue from the iovec position, pipe buffer offset and
+remaining length where the first attempt failed, but currently the
+pipe buffer offset and remaining length are reset. This will corrupt
+the piped data (possibly also leading to an information leak between
+processes) and may also corrupt kernel memory.
+
+This was fixed upstream by commits f0d1bec9d58d ("new helper:
+copy_page_from_iter()") and 637b58c2887e ("switch pipe_read() to
+copy_page_to_iter()"), but those aren't suitable for stable. This fix
+for older kernel versions was made by Seth Jennings for RHEL and I
+have extracted it from their update.
+
+CVE-2015-1805
