From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>
The patches are divided into two parts:
1) A set of SUNRPC patches to fix and clean up the XDR decoding
operations that are used by READ_PLUS, READ and READDIR. The main focus
is on the operations used to shift data left and right in pages.
2) A set of patches to the NFSv4.2 READ_PLUS client code. These mainly
try to fix issues around bounds checking, but also fix at least one
protocol conformance problem.

v2: - Fix corner cases when calling xdr_shrink_bufhead() and
xdr_shrink_pagelen() with shorter values of buf->len
- Fix xdr_buf helper functions to take a length parameter so we can
optimise shorter values of buf->len more easily.
- Fix issues with sparse pages reported by Tigran
- Disable use of READ_PLUS in pNFS.
- Move nfsd patches into a separate series.
Trond Myklebust (15):
SUNRPC: _shift_data_left/right_pages should check the shift length
SUNRPC: Fixes for xdr_align_data()
SUNRPC: Fix xdr_expand_hole()
SUNRPC: Cleanup xdr_shrink_bufhead()
SUNRPC: _copy_to/from_pages() now check for zero length
SUNRPC: Clean up open coded setting of the xdr_stream 'nwords' field
SUNRPC: Cleanup - constify a number of xdr_buf helpers
SUNRPC: When expanding the buffer, we may need grow the sparse pages
NFSv4.2: Ensure we always reset the result->count in
decode_read_plus()
NFSv4.2: decode_read_plus_data() must skip padding after data segment
NFSv4.2: decode_read_plus_hole() needs to check the extent offset
NFSv4.2: Handle hole lengths that exceed the READ_PLUS read buffer
NFSv4.2: Don't error when exiting early on a READ_PLUS buffer overflow
NFSv4.2: Deal with potential READ_PLUS data extent buffer overflow
NFSv4.2/pnfs: Don't use READ_PLUS with pNFS yet
