2002-06-11Remove some unused code for dealing with nfs over kerberos. No actual change,Hans Insulander
just some #ifdef'ed out code removed. ok deraadt@, art@ and csapuntz@
2002-06-11splassert where comments tell us to.Artur Grabowski
2002-06-02correct fake nfs_boot_getfh(); ski@wuhjuhbuh.2y.netTheo de Raadt
2002-05-21Protect calls to biodone with splbio. Some functions calledArtur Grabowski
by biodone assume splbio (probably just on other filesystems) and some callbacks from b_iodone assume it too. It's just much safer. costa@ ok.
2002-05-17Fix nfs_realign to allocate new mbufs. Taken from freebsdConstantine Sapuntzakis
2002-05-10Fix for PR2641. Length calculation was wrong in loop. Include commentConstantine Sapuntzakis

2002-02-23Sigh. The diff is out for testing for three months without a single problem.Artur Grabowski
Two days after commit people report serious lockups all over the place. Back out nfs locking changes.
2002-02-22More locking in the NFS codeConstantine Sapuntzakis
2002-02-12Fix all users of getsock to use FREF/FRELE properly.Artur Grabowski
2002-02-10theo doesn't like this codeNathan Binkert
2002-02-08- Rename FILE_{,UN}USE to FREF and FRELE. USE is a bad verb and we don't haveArtur Grabowski
the same semantics as NetBSD anyway, so it's good to avoid name collissions. - Always fdremove before freeing the file, not the other way around. - falloc FREFs the file. - have FILE_SET_MATURE FRELE the file (It feels like a good ortogonality to falloc FREFing the file). - Use closef as much as possible instead of ffree in error paths of falloc:ing functions. closef is much more careful with the fd and can deal with the fd being forcibly closed by dup2. Also try to avoid manually calling *fo_close when closef can do that for us (this makes some error paths mroe complicated (sys_socketpair and sys_pipe), but others become simpler (sys_open)).
2002-02-08There are NFS servers where it's possible to modify a symbolic link. Remove ↵Constantine Sapuntzakis
aggressive optimization
2002-02-05Add counting of temporary references to a struct file (as opposed to referencesArtur Grabowski
from fd tables and other long-lived objects). This is to avoid races between using a file descriptor and having another process (with shared fd table) close it. We use a separate refence count so that error values from close(2) will be correctly returned to the caller of close(2). The macros for those reference counts are FILE_USE(fp) and FILE_UNUSE(fp). Make sure that the cases where closef can be called "incorrectly" (most notably dup2(2)) are handled. Right now only callers of closef (and {,p}read) use FILE_{,UN}USE correctly, more fixes incoming soon.

2002-01-23Pool deals fairly well with physical memory shortage, but it doesn't dealArtur Grabowski
well (not at all) with shortages of the vm_map where the pages are mapped (usually kmem_map). Try to deal with it: - group all information the backend allocator for a pool in a separate struct. The pool will only have a pointer to that struct. - change the pool_init API to reflect that. - link all pools allocating from the same allocator on a linked list. - Since an allocator is responsible to wait for physical memory it will only fail (waitok) when it runs out of its backing vm_map, carefully drain pools using the same allocator so that va space is freed. (see comments in code for caveats and details). - change pool_reclaim to return if it actually succeeded to free some memory, use that information to make draining easier and more efficient. - get rid of PR_URGENT, noone uses it.
2002-01-20Move nfs_norsvport out from behind #ifdef NFSSERVER so ramdiskHugh Graham
kernels with only NFSCLIENT defined can build.

2001-12-22Init the creds in nfs_open too.Artur Grabowski
Repairs swap over nfs. Tested by hugh@
2001-12-19UBC was a disaster. It worked very good when it worked, but on someArtur Grabowski
machines or some configurations or in some phase of the moon (we actually don't know when or why) files disappeared. Since we've not been able to track down the problem in two weeks intense debugging and we need -current to be stable, back out everything to a state it had before UBC. We apologise for the inconvenience.
2001-12-14Workaround a compiler bug on m68k.Artur Grabowski
2001-12-11minor fixes.Artur Grabowski
2001-12-10Big cleanup inspired by NetBSD with some parts of the code from NetBSD.Artur Grabowski
- get rid of VOP_BALLOCN and VOP_SIZE - move the generic getpages and putpages into miscfs/genfs - create a genfs_node which must be added to the top of the private portion of each vnode for filsystems that want to use genfs_{get,put}pages - rename genfs_mmap to vop_generic_mmap
2001-12-10Merge in struct uvm_vnode into struct vnode.Artur Grabowski
2001-12-04Readd VOP_MMAP, will be used soon. Right now it's just a question toArtur Grabowski
the filesystem if we're allowed to mmap the file.

2001-11-29Correctly handle b_vp with bgetvp and brelvp in {get,put}pages.Artur Grabowski
Prevents panics caused by vnodes being recycled under our feet.
2001-11-27Merge in the unified buffer cache code as found in NetBSD 2001/03/10. TheArtur Grabowski
code is written mostly by Chuck Silvers <chuq@chuq.com>/<chs@netbsd.org>. Tested for the past few weeks by many developers, should be in a pretty stable state, but will require optimizations and additional cleanups.
2001-11-15Remove creds from struct buf, move the creds that nfs need into the nfs node.Artur Grabowski
While in the area, convert nfs node allocation from malloc to pool and do some cleanups. Based on the UBC changes in NetBSD. niklas@ ok.

2001-07-26Back out changes to symlink and mknod that were not well tested.Todd C. Miller
A simple mknod at causes a kernel panic (uvm_fault).
2001-07-26change vop_symlink and vop_mknod to return vpp (the created node)assar
