kernel/linux.git/net/sunrpc/auth_null.c, branch v6.12.80Linux kernel stable tree (mirror)https://git.radix-linux.su/kernel/linux.git/atom?h=v6.12.802019-02-14T16:48:36+00:00SUNRPC: Add rpc_auth::au_ralign field2019-02-14T16:48:36+00:00Chuck Leverchuck.lever@oracle.com2019-02-11T16:25:36+00:00urn:sha1:35e77d21baa04b554bf3dc9a08dfa7e569286e51
Currently rpc_inline_rcv_pages() uses au_rslack to estimate the
size of the upper layer reply header. This is fine for auth flavors
where au_verfsize == au_rslack.
However, some auth flavors have more going on. krb5i for example has
two more words after the verifier, and another blob following the
RPC message. The calculation involving au_rslack pushes the upper
layer reply header too far into the rcv_buf.
au_rslack is still valuable: it's the amount of buffer space needed
for the reply, and is used when allocating the reply buffer. We'll
keep that.
But, add a new field that can be used to properly estimate the
location of the upper layer header in each RPC reply, based on the
auth flavor in use.

au_verfsize will be needed for a non-flavor-specific computation
in a subsequent patch.

This now always just does get_rpccred(), so we
don't need an operation pointer to know to do that.
