features/access-control: skip access-tests if the call is from fuse

2011-01-27T07:42:21+00:00

Fuse cant send aux gids. So access-control checks treat
non-primary-group membership of user as "other". So skip
access-control checks if the call is from fuse. We added a hack to
treat all calls with pid set to 1 as calls from nfs. So for calls with pid
not 1 we skip the access-control checks on all fops.

nfs: Introduce tunable for memory consumption

2011-01-12T07:58:33+00:00

NFS has used a common define called the mem-factor to determine
how much memory is allocated for the following items:

o inode table
o local structures used by nfs for storing fop state
o local structures used by nfs3 for storing nfs op state

These are all allocated through the mem-pool. The factor is multiplied by
a multiple that is specific to each data structure. For eg.

define GF_NFS_CONCURRENT_OPS_MULT     15
define GF_NFS_INODE_LRU_MULT          6000

The first value is used for allocating a mem-pool for storing
state for each fop or nfs op that is currently being handled. Knowing that linux
allows at most 128 in-flight requests, this multiple combined with the default
mem-factor of 15 gives us 225 slots in the mem-pool for the local structures.

Similarly, 6000*15 gives us a space of 90k inodes in the lru.

That means, increasing the common mem-factor will allow increasing the perf
under some conditions. This patch introduces the mem-factor as a configurable
option.

nfs: Support subdirectory exports

2010-12-29T18:20:36+00:00

Enable exporting directories as separate exports. Even though the directories
wont show up in showmount output, they'll still be mount'able.

The new option:

        nfs.export-dirs 

is enabled by default so that users dont have to wait till this option
is incorporated into the gluster command line.
