dogcow 372e6ef309 now that we have -Wno-unused-parameter, back out all the tremendously ugly 
code to gratuitously access said parameters.

christos 3b347a3429 another variable should have been _KERNEL only. 2006-10-17 14:55:13 +00:00
christos 0a3d351aae don't expose kernel variables to userland. 2006-10-17 14:53:54 +00:00
yamt 583781abd3 grab glock when calling uvm_unp_setsize, so that it doesn't interfere 
mmap'ed accesses.  this fixes an assertion failure in in nfs_doio_read.
("vp->v_size >= uiop->uio_offset + uiop->uio_resid")

dogcow 44603cac1f more unused variable fallout. 2006-10-13 18:28:06 +00:00
christos 4d595fd7b1 - sprinkle __unused on function decls. 
- fix a couple of unused bugs
- no more -Wno-unused for i386
 2006-10-12 01:30:41 +00:00
dogcow 55ddfc9aae change the MOWNER_INIT define to take two args; fix extant struct mowner 
decls to use it. Makes options MBUFTRACE compile again and not whinge about
missing structure declarations. (Also makes initialization consistent.)

drochner 429dff1c3d Flush regular files before setattr also if the mode bits are going to 
be set. Linux NFS servers (at least) reset suid/sgid bits if a write
happens afterwards. Add a comment why this is done.
This fixes system builds on diskless systems for me where suid bits
were missing after install(1).
Approved by yamt.

yamt ff1a471a3b nfs_ispublicfh: fix another instance of cast-qual. 2006-09-04 08:38:16 +00:00
yamt 80fe9dcf8f remove (void *) cast from NFSRVFH_DATA as it sometimes 
discards const qualifier.  pointed out by Havard Eidnes.
(it wasn't detected by in-tree gcc4.  seems like a compiler bug.)

christos da9052a357 Don't free what we did not allocate. 2006-08-24 12:40:39 +00:00
christos f73c6e5980 Change iostat_alloc() to take the parent pointer and the name directly, so 
that callers are not responsible for initializing the fields. Store the name
inside the struct instead of maintaining a pointer to external storage, or
leaked memory (nfs case).

christos 1c50629119 When there are too many empty entries in a row, and we need to try to 
read the next block, free the cookie buffer before doing so to avoid
a memory leak. Reported by  Mark Davies.

yamt b0c4bb36d9 nfs_getreq: fix a kauth fallout.

martin a3b5baed42 Fix alignement problems for fhandle_t, exposed by gcc4.1. 
While touching all vptofh/fhtovp functions, get rid of VFS_MAXFIDSIZ,
version the getfh(2) syscall and explicitly pass the size available in
the filehandle from userland.

Discussed on tech-kern, with lots of help from yamt (thanks!).

yamt ce1a2b18c3 some comments taken from Jed Davis's patch. 2006-07-01 11:30:44 +00:00
yamt e38f237e53 if a file is sillyrename'ed because it's a destination of rename, 
make sillyrename (try to) use LINK operation rather than RENAME.
PR/33861 from Jed Davis.  he provided the almost same patch.
according to him, it also happen to be what opensolaris does in this case.

from the PR:
> In nfs_rename(), if the destination appears to exist and is "in use"
> (this check is apparently satisfied even if the file isn't in use by
> anything except the rename itself), it will sillyrename it, then delete
> the sillyrenamed file even if the rename fails -- for instance, because
> the "from" file no longer exists on the server.

> mkdir a b; touch a/x; perl -e 'fork(); rename("a/x","b/x") or die "$!\n"'
>
> Afterwards, neither a/x nor b/x will exist.

> 1) Lookup of b/x; fails with NOENT.
> 2) Rename from a/x to b/x; succeeds.
> 3) Lookup of b/x; fails with NOENT.
> 4) Rename from b/x to b/.nfsA23a3; succeeds.
> 5) Rename from a/x to b/x; fails with NOENT.
> 6) Remove of b/.nfsA23a3; succeeds.

kardel de4337ab21 merge FreeBSD timecounters from branch simonb-timecounters 
- struct timeval time is gone
  time.tv_sec -> time_second
- struct timeval mono_time is gone
  mono_time.tv_sec -> time_uptime
- access to time via
	{get,}{micro,nano,bin}time()
	get* versions are fast but less precise
- support NTP nanokernel implementation (NTP API 4)
