seq_file: constify seq_operations

2009-09-23T14:39:29+00:00

Make all seq_operations structs const, to help mitigate against
revectoring user-triggerable function pointers.

This is derived from the grsecurity patch, although generated from scratch
because it's simpler than extracting the changes from there.

nfsd: return success for non-NFS4 nfs4_state_start

2009-09-17T15:30:32+00:00

Today's linux-next build (sparc64_defconfig) failed like this:

In file included from arch/sparc/kernel/sys_sparc32.c:32:
include/linux/nfsd/nfsd.h: In function 'nfs4_state_start':
include/linux/nfsd/nfsd.h:177: error: no return statement in function returning non-void

Caused by commit 29ab23cc5d351658d01a4327d55e9106a73fd04f ("nfsd4: allow
nfs4 state startup to fail").  Please, if you add code that depends on a
CONFIG option, build with that option enabled and disabled.

nfsd4: allow nfs4 state startup to fail

2009-09-16T00:49:33+00:00

The failure here is pretty unlikely, but we should handle it anyway.

nfsd41: hange from page to memory based drc limits

2009-07-28T18:30:05+00:00

NFSD_SLOT_CACHE_SIZE is the size of all encoded operation responses
(excluding the sequence operation) that we want to cache.

For now, keep NFSD_SLOT_CACHE_SIZE at PAGE_SIZE. It will be reduced
when the DRC is changed from page based to memory based.

nfsd41: use globals for DRC limits

2009-07-14T21:52:40+00:00

The version 4.1 DRC memory limit and tracking variables are server wide and
session specific. Replace struct svc_serv fields with globals.
Stop using the svc_serv sv_lock.

Add a spinlock to serialize access to the DRC limit management variables which
change on session creation and deletion (usage counter) or (future)
administrative action to adjust the total DRC memory limit.

nfsd41: control nfsv4.1 svc via /proc/fs/nfsd/versions

2009-04-04T00:41:21+00:00

Support enabling and disabling nfsv4.1 via /proc/fs/nfsd/versions
by writing the strings "+4.1" or "-4.1" correspondingly.

Use user mode nfs-utils (rpc.nfsd option) to enable.
This will allow us to get rid of CONFIG_NFSD_V4_1
