SUNRPC: Teach server to recognize RPC_AUTH_TLS

2022-02-28T15:26:40+00:00

Initial support for the RPC_AUTH_TLS authentication flavor enables
NFSD to eventually accept an RPC_AUTH_TLS probe from clients. This
patch simply prevents NFSD from rejecting these probes completely.

In the meantime, graft this support in now so that RPC_AUTH_TLS
support keeps up with generic code and API changes in the RPC
server.

Down the road, server-side transport implementations will populate
xpo_start_tls when they can support RPC-with-TLS. For example, TCP
will eventually populate it, but RDMA won't.

SUNRPC: Add svc_rqst::rq_auth_stat

2021-08-10T18:18:35+00:00

I'd like to take commit 4532608d71c8 ("SUNRPC: Clean up generic
dispatcher code") even further by using only private local SVC
dispatchers for all kernel RPC services. This change would enable
the removal of the logic that switches between
svc_generic_dispatch() and a service's private dispatcher, and
simplify the invocation of the service's pc_release method
so that humans can visually verify that it is always invoked
properly.

All that will come later.

First, let's provide a better way to return authentication errors
from SVC dispatcher functions. Instead of overloading the dispatch
method's *statp argument, add a field to struct svc_rqst that can
hold an error value.

sunrpc: check that domain table is empty at module unload.

2020-05-28T22:15:00+00:00

The domain table should be empty at module unload.  If it isn't there is
a bug somewhere.  So check and report.

SUNRPC: Trace gssproxy upcall results

2019-10-30T20:32:07+00:00

Record results of a GSS proxy ACCEPT_SEC_CONTEXT upcall and the
svc_authenticate() function to make field debugging of NFS server
Kerberos issues easier.

treewide: Add SPDX license identifier for missed files

2019-05-21T08:50:45+00:00

Add SPDX license identifiers to all files which:

 - Have no license information of any form

 - Have EXPORT_.*_SYMBOL_GPL inside which was used in the
   initial scan/conversion to ignore the file

These files fall under the project license, GPL v2 only. The resulting SPDX

SUNRPC: Add lockless lookup of the server's auth domain

2018-10-03T15:32:59+00:00

Avoid taking the global auth_domain_lock in most lookups of the auth domain
by adding an RCU protected lookup.

SUNRPC: Remove the server 'authtab_lock' and just use RCU

2018-10-03T15:32:59+00:00

Module removal is RCU safe by design, so we really have no need to
lock the 'authtab[]' array.

locking/atomic, kref: Implement kref_put_lock()

2017-01-18T09:03:29+00:00

Because home-rolling your own is _awesome_, stop doing it. Provide
kref_put_lock(), just like kref_put_mutex() but for a spinlock.
