nfsd: Move private headers to source directory

nfsd module. Move them to the source directory

nfsd: Headers Independence and include cleanups

2009-12-14T23:12:09+00:00

* Add includes that are directly used by headers
* Remove includes that are not needed

These are the changes made:

[xdr.h]
struct nfsd_readdirres has an embedded struct readdir_cd from nfsd.h
fixing that we can drop other includes

[xdr4.h]
embedded types defined both at state.h and nfsd.h

[syscall.h]
After export.h fix none of these stuff is needed.
fix extra space in # include <> statement

[stats.h]
does not need  but was export to user-mode
so I don't touch it

[state.h]
embedded types from nfsfh.h like struct knfsd_fh. bringing that
eliminates the need for all other includes

[nfsfh.h]
directly manipulating types from sunrpc/svc.h.
Removed Other unused headers.

[nfsd.h]
removed unused headers include

[export.h]
lots of sunrpc/svc.h types and a single prototype declaration
with pointer from nfsfh.h, but all users of export.h do need
nfsfh.h any way. remove now un-needed include.

[const.h]
Unfixed (not independent)

[cache.h]
could do with a forward declaration of "struct svc_rqst;"
from sunrpc/svc.h but all users absolutely will need
sunrpc/svc.h it is easier overall this way.

nfsd: make fs/nfsd/vfs.h for common includes

2009-11-13T18:23:02+00:00

None of this stuff is used outside nfsd, so move it out of the common
linux include directory.

Actually, probably none of the stuff in include/linux/nfsd/nfsd.h really
belongs there, so later we may remove that file entirely.

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':

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.
