SUNRPC: Add a helper function xdr_stream_decode_string_dup()

2017-02-21T21:56:16Z

Create a helper function that decodes a xdr string object, allocates a memory buffer and then store it as a NUL terminated string. Signed-off-by: Trond Myklebust Reviewed-by: Chuck Lever Signed-off-by: Anna Schumaker

SUNRPC: Add generic helpers for xdr_stream encode/decode

SUNRPC: Refactor rpc_xdr_buf_init()

2016-09-19T17:08:37Z

Clean up: there is some XDR initialization logic that is common to the forward channel and backchannel. Move it to an XDR header so it can be shared. rpc_rqst::rq_buffer points to a buffer containing big-endian data. Update its annotation as part of the clean up.

rpc: define xdr_restrict_buflen

With this xdr_reserve_space can help us enforce various limits. Signed-off-by: J. Bruce Fields

nfsd4: allow encoding across page boundaries

2014-05-30T21:31:54Z

After this we can handle for example getattr of very large ACLs. Read, readdir, readlink are still special cases with their own limits. Also we can't handle a new operation starting close to the end of a page. Signed-off-by: J. Bruce Fields

rpc: xdr_truncate_encode

2014-05-30T21:31:47Z

This will be used in the server side in a few cases: - when certain operations (read, readdir, readlink) fail after encoding a partial response. - when we run out of space after encoding a partial response. - in readlink, where we initially reserve PAGE_SIZE bytes for data, then truncate to the actual size.

sunrpc: trim off trailing checksum before returning decrypted or integrity authenticated buffer

2013-02-08T20:19:10Z

When GSSAPI integrity signatures are in use, or when we're using GSSAPI privacy with the v2 token format, there is a trailing checksum on the xdr_buf that is returned. It's checked during the authentication stage, and afterward nothing cares about it. Ordinarily, it's not a problem since the XDR code generally ignores it, but it will be when we try to compute a checksum over the buffer to help prevent XID collisions in the duplicate reply cache. Fix the code to trim off the checksums after verifying them. Note that in unwrap_integ_data, we must avoid trying to reverify the checksum if the request was deferred since it will no longer be present when it's revisited. Signed-off-by: Jeff Layton
