NFS: Enabling v4.2 should not recompile nfsd and lockd

2013-11-19T21:20:40+00:00

When CONFIG_NFS_V4_2 is toggled nfsd and lockd will be recompiled, instead of only the nfs client. This patch moves a small amount of code into the client directory to avoid unnecessary recompiles. Signed-off-by: Anna Schumaker Signed-off-by: Trond Myklebust

NFSv4: Move the DNS resolver into the NFSv4 module

2013-06-18T17:47:18+00:00

The other protocols don't use it, so make it local to NFSv4, and remove the EXPORT. Also ensure that we only compile in cache_lib.o if we're using the legacy DNS resolver. Signed-off-by: Trond Myklebust Cc: Bryan Schumaker

SUNRPC: remove "cache_request" argument in sunrpc_cache_pipe_upcall() function

2013-02-15T15:43:47+00:00

Passing this pointer is redundant since it's stored on cache_detail structure, which is also passed to sunrpc_cache_pipe_upcall () function. Signed-off-by: Stanislav Kinsbursky Signed-off-by: J. Bruce Fields

SUNRPC: introduce cache_detail->cache_request callback

2013-02-15T15:43:45+00:00

This callback will allow to simplify upcalls in further patches in this series. Signed-off-by: Stanislav Kinsbursky Signed-off-by: J. Bruce Fields

NFS: simplify and clean cache library

2013-02-15T15:43:36+00:00

This is a cleanup patch. Such helpers like nfs_cache_init() and nfs_cache_destroy() are redundant, because they are just a wrappers around sunrpc_init_cache_detail() and sunrpc_destroy_cache_detail() respectively. So let's remove them completely and move corresponding logic to nfs_cache_register_net() and nfs_cache_unregister_net() respectively (since they are called together anyway).

NFS: use SUNRPC cache creation and destruction helper for DNS cache

2013-02-15T15:43:12+00:00

This cache was the first containerized and doesn't use net-aware cache creation and destruction helpers. This is a cleanup patch which just makes code looks clearer and reduce amount of lines of code. Signed-off-by: Stanislav Kinsbursky Signed-off-by: J. Bruce Fields

sunrpc: move address copy/cmp/convert routines and prototypes from clnt.h to addr.h

2013-02-05T14:41:14+00:00

These routines are used by server and client code, so having them in a separate header would be best. Signed-off-by: Jeff Layton Acked-by: Trond Myklebust Signed-off-by: J. Bruce Fields

NFS: fix bug in legacy DNS resolver.

2012-10-31T20:25:59+00:00

The DNS resolver's use of the sunrpc cache involves a 'ttl' number (relative) rather that a timeout (absolute). This confused me when I wrote commit c5b29f885afe890f953f7f23424045cdad31d3e4 "sunrpc: use seconds since boot in expiry cache" and I managed to break it. The effect is that any TTL is interpreted as 0, and nothing useful gets into the cache. This patch removes the use of get_expiry() - which really expects an expiry time - and uses get_uint() instead, treating the int correctly as a ttl. This fixes a regression that has been present since 2.6.37, causing certain NFS accesses in certain environments to incorrectly fail.

NFS: Convert v4 into a module

2012-07-30T23:06:52+00:00

This patch exports symbols needed by the v4 module. In addition, I also switch over to using IS_ENABLED() to check if CONFIG_NFS_V4 or CONFIG_NFS_V4_MODULE are set. The module (nfs4.ko) will be created in the same directory as nfs.ko and will be automatically loaded the first time you try to mount over NFS v4.

NFS: Fix a number of sparse warnings

2012-03-11T19:14:16+00:00

Fix a number of "warning: symbol 'foo' was not declared. Should it be static?" conditions. Fix 2 cases of "warning: Using plain integer as NULL pointer" fs/nfs/delegation.c:263:31: warning: restricted fmode_t degrades to integer - We want to allow upgrades to a WRITE delegation, but should otherwise consider servers that hand out duplicate delegations to be borken.
