SUNRPC: move bkl locking and xdr proc invocation into a common helper

2007-07-19T19:21:39+00:00

Since every invocation of xdr encode or decode functions takes the BKL now,
there's a lot of redundant lock_kernel/unlock_kernel pairs that we can pull
out into a common function.

knfsd: nfsd4: secinfo handling without secinfo= option

2007-07-17T17:23:08+00:00

We could return some sort of error in the case where someone asks for secinfo
on an export without the secinfo= option set--that'd be no worse than what
we've been doing.  But it's not really correct.  So, hack up an approximate
secinfo response in that case--it may not be complete, but it'll tell the
client at least one acceptable security flavor.

knfsd: nfsd: set rq_client to ip-address-determined-domain

2007-07-17T17:23:07+00:00

We want it to be possible for users to restrict exports both by IP address and
by pseudoflavor.  The pseudoflavor information has previously been passed
using special auth_domains stored in the rq_client field.  After the preceding
patch that stored the pseudoflavor in rq_pflavor, that's now superfluous; so
now we use rq_client for the ip information, as auth_null and auth_unix do.

However, we keep around the special auth_domain in the rq_gssclient field for
backwards compatibility purposes, so we can still do upcalls using the old
"gss/pseudoflavor" auth_domain if upcalls using the unix domain to give us an
appropriate export.  This allows us to continue supporting old mountd.

In fact, for this first patch, we always use the "gss/pseudoflavor"
auth_domain (and only it) if it is available; thus rq_client is ignored in the
auth_gss case, and this patch on its own makes no change in behavior; that
will be left to later patches.

Note on idmap: I'm almost tempted to just replace the auth_domain in the idmap
upcall by a dummy value--no version of idmapd has ever used it, and it's
unlikely anyone really wants to perform idmapping differently depending on the
where the client is (they may want to perform *credential* mapping
differently, but that's a different matter--the idmapper just handles id's
used in getattr and setattr).  But I'm updating the idmapd code anyway, just
out of general backwards-compatibility paranoia.

knfsd: nfsd4: store pseudoflavor in request

2007-07-17T17:23:07+00:00

Add a new field to the svc_rqst structure to record the pseudoflavor that the
request was made with.  For now we record the pseudoflavor but don't use it
for anything.

SUNRPC client: add interface for binding to a local address

2007-07-11T03:40:49+00:00

In addition to binding to a local privileged port the NFS client should
allow binding to a specific local address. This is used by the server
for callbacks. The patch adds the necessary interface.

SUNRPC server: record the destination address of a request

Save the destination address of an incoming request over TCP like is
done already for UDP. It is necessary later for callbacks by the server.

rename rpcb_getport_external as rpcb_get_port_sync, and make it available
always (instead of only when CONFIG_ROOT_NFS is enabled).

SUNRPC: Remove the tk_auth macro...

2007-07-11T03:40:37+00:00

We should almost always be deferencing the rpc_auth struct by means of the
credential's cr_auth field instead of the rpc_clnt->cl_auth anyway. Fix up
that historical mistake, and remove the macro that propagated it.
