1ca2839e35 When NFS_V2_ONLY is defined, refuse to mount NFSv3 and NQNFS filesystems,
rather than pretending they're NFSv2 and hoping for the best.  Fix based on

4442920f51 In nfs_loadattrcache(), if checkalias() gives us a new vnode, lock it. This
prevents us losing the locked state of the old vnode.

fvdl thinks the old vnode is certain to be locked at this point.  I've put in
a KASSERT to be on the safe side.

This seems to fix PR kern/12661.

9dc4bbb990 Don't forget to unlock the vnode returned by cache_lookup if the

5b35dc8136 When unmounting a file system, acquire the syncer_lock before
vfs_busy'ing just before the dounmount() call.  This is to avoid
sleeping with the mountlist_slock held -- but we must acquire
syncer_lock before vfs_busy because the syncer itself uses
syncer_lock -> vfs_busy locking order.

dd82ad8e2c eliminate the VM_PAGER_* error codes in favor of the traditional E* codes.
the mapping is:

VM_PAGER_OK		        0
VM_PAGER_BAD		        <unused>
VM_PAGER_FAIL		        <unused>
VM_PAGER_PEND		        0 (see below)
VM_PAGER_ERROR		        EIO
VM_PAGER_AGAIN		        EAGAIN
VM_PAGER_UNLOCK		        EBUSY
VM_PAGER_REFAULT	        ERESTART

for async i/o requests, it used to be possible for the request to
be convert to sync, and the pager would return VM_PAGER_OK or VM_PAGER_PEND
to indicate whether the caller should perform post-i/o cleanup.
this is no longer allowed; pagers must now return 0 to indicate that
the async i/o was successfully started, and the caller never needs to
worry about doing the post-i/o cleanup.

5706160195 fix several bugs:
- in the cases where we skip over the i/o loop, increment npages by ridx
   so that when the cleanup code starts processing the pgs array at index 0
   it'll actually process all of the pages.
 - process the PG_RELEASED flag when unbusying pages.
 - add some missing MP locking.
 - use MIN() and MAX() instead of min() and max() since the latter are
   functions which take arguments of type "int" but we call them with
   values of type "off_t", so the values could be truncated.

clean after themselves before unloading. This fixes random panics

ff0b960398 Fix bug in error handling for NFSv3 + nqnfs.
With nfsv2, the nfsm_reply() macro always causes the service routine
to return if error was nonzero.

With nfsv3, we can keep going after nfsm_reply() without returning,
but nqnfsrv_getlease() didn't take this into account, so add a
return(0) after each error-case nfsm_reply(0).

fb526e055c Substantial signal handling changes:
* Increase the size of sigset_t to accomodate 128 signals -- adding new
  versions of sys_setprocmask(), sys_sigaction(), sys_sigpending() and
  sys_sigsuspend() to handle the changed arguments.
* Abstract the guts of sys_sigaltstack(), sys_setprocmask(), sys_sigaction(),
  sys_sigpending() and sys_sigsuspend() into separate functions, and call them
  from all the emulations rather than hard-coding everything.  (Avoids uses
  the stackgap crap for these system calls.)
* Add a new flag (p_checksig) to indicate that a process may have signals
  pending and userret() needs to do the full (slow) check.
* Eliminate SAS_ALTSTACK; it's exactly the inverse of SS_DISABLE.
* Correct emulation bugs with restoring SS_ONSTACK.
* Make the signal mask in the sigcontext always use the emulated mask format.
* Store signals internally in sigaction structures, rather than maintaining a
  bunch of little sigsets for each SA_* bit.
* Keep track of where we put the signal trampoline, rather than figuring it out
  in *_sendsig().
* Issue a warning when a non-emulated sigaction bit is observed.
* Add missing emulated signals, and a native SIGPWR (currently not used).
* Implement the `not reset when caught' semantics for relevant signals.

Note: Only code touched by the i386 port has been modified.  Other ports and
emulations need to be updated.

651b44e211 Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

the directory cache as translation table. See nfs_subs.c for comments.
  Makes the code a bit more complex to look at than I would have liked,
  but doesn't affect the speed of the default behavior.
* Optimize caching behavior a bit when buffers are invalidated.
* Save some RPCs in readdir operations by not bothering if there is
  a small amount left to do to fill the buffer. It'll be done in the
  next RPC with a larger chunk anyway. Wastes a bit of buffer space
  but is faster.
* Make n_vattr an allocated vattr struct. This avoids nfsnode bloat,
  and is friendlier to the malloc routines.

c437b55ca7 A filesystem may not support VFS_VGET (like msdosfs). If it doesn't,
the server code would always skip all dir entries for a readdirplus
operation. To avoid endlessly retrying clients, try VFS_VGET first,
and it it fails, return NFSERR_NOTSUPP so that client will fall
back to normal readdir operations.

8c0a9bab00 Don't cast 64bit (off_t) file sizes to vm_offset_t (32bit on many
architectures), truncate them intelligently instead.
The truncation is done centralized in vnode_pager.c.
This prevents from wrap-over effects when parts of large (>2^32 byte) files
are mmapped.
Don't allow to mmap above the numerical range of vm_offset_t.
This is considered a temporary solution until the vm system handles the
object sizes/offsets more cleanly.
