hannken a3a898ff0f Add the gating of system calls that cause modifications to the underlying
file system.
The function vfs_write_suspend stops all new write operations to a file
system, allows any file system modifying system calls already in progress
to complete, then sync's the file system to disk and returns. The
function vfs_write_resume allows the suspended write operations to
complete.

From FreeBSD with slight modifications.

yamt f2aa877507 for nfs_timer_ch, use callout_schedule rather than callout_reset
as the former is a little more efficient.

yamt c2025ab0ea change n_mtime from time_t to timespec in order to improve
cache consistency.

yamt 883426c958 don't call nfs_delayedtruncate() from nfs_getpages().
it causes simplelock deadlock.

there can be too many activities in a second.

yamt 3fcbf88d41 current trylater/jukebox retry delay is way too long and
it has a bug in the backoff calculation. so,
- clip it to 1-60 sec. (suggested by Rick Macklem)
- use a constant multiplier instead of nfs_backoff, which
  is already exponential.
- move some related constant definations to nfs.h from nqnfs.h and
  prefix with NFS_ instead of NQ_ because they are not nqnfs-specific.

bouyer a678ebca13 nfsrv_commit(): return success and don't do anything for requests which starts
past the end of the file. This can happen when two clients are writting to
the same file.
Close PR 21696 by myself, discussed on tech-net in 2003/05 and 2003/06.
Issue raised by Chuck Silvers (commit and truncate ops needs to be serialised)
still unadressed.

fvdl d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.
2003-06-29 22:28:00 +00:00
thorpej a06b275edc Undo part of the ktrace/lwp changes. In particular:
* Remove the "lwp *" argument that was added to vget().  Turns out
  that nothing actually used it!
* Remove the "lwp *" arguments that were added to VFS_ROOT(), VFS_VGET(),
  and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted
  above, didn't use it).
* Remove all of the "lwp *" arguments to internal functions that were added
  just to appease the above.
2003-06-29 18:43:21 +00:00
darrenr 960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V

yamt ff974db6fd if nfs_writerpc() splitted an unstable write into some rpcs and
write verifier was changed, we should restart from the first.

yamt 45c519f76f - instead of scaning a list when looking up
{a idle thread, a socket with pending requests},
  maintain dedicated list of them.
- add spin locks.

martin d505b18964 Make sure to include opt_foo.h if a defflag option FOO is used. 2003-06-23 11:00:59 +00:00
yamt 9c329a66d1 rework zero padding of rpc reply.
- for READ procedure, don't send back more bytes than requested.
- don't have doubtful assumptions on mbuf chain structure.
- rename a function (nfsm_adj -> nfs_zeropad) to avoid confusion as
  the semantics of the function was changed.

yamt bcf2e4f22f fix a problem in 'protected' case of writerpc.
retransmitted mbufs can survive even after requests themselves
finished.  so, before unbusy pages, make sure that mbufs referring them
go away.

yamt 85d0052723 workaround for UBC limit.
while our nfsd announces MAXBSIZE as wtmax for tcp,
VOP_GETPAGES of filesystems that uses genfs_getpages can't
handle >= MAX_READ_AHEAD(16) pages at once.
therefore, depending on PAGE_SIZE of the machine and file offset of
a read request, we can't VOP_GETPAGES the range at once.

yamt a340c1b544 when a result of NFSv3 READLINK is too long for us,
return ENAMETOOLONG rather than EBADRPC.
(it's our implementation limit, not protocol limit.)
