mycroft 2bc736661a Implement poll(2). 1996-09-07 12:40:22 +00:00
mycroft c52352c819 Add a set of generic file system operations that most file systems use.
Also, fix some time stamp bogosities.

thorpej 5404d54edb Another %lx -> %x for ntohl() 1996-08-14 03:47:42 +00:00
cgd 2af08e028e print result of ntohl/htonl as a long. 1996-07-10 18:43:23 +00:00
fvdl 90b2034c7c Use the right time for v3 setattr operation. 1996-07-07 12:25:47 +00:00
fvdl 88eff7ea92 Start XIDs at a value based on the current time, not 0. This avoids nasty
XID confusions with servers that cache them over a long period and
with clients that reboot quickly.

Problems: because of the sanity check that is done by comparing the system
time with filesystem time, XIDs will start at 0 until root is mounted,
which means it isn't completely safe for diskless setups. But it's clearly
better than it was. It would also be cleaner if all XID handling (more
generally, all RPC handling) within the kernel went through the
same functions.

fvdl 0f6afee9a7 Remove bogus check on record length < NFS_MINPACKET.
(From Guy Harris via Rick Macklem).
1996-07-02 23:21:15 +00:00
fvdl 1e8262b3d6 Don't mistake a non-async block that needs to be commited for an
interrupted write.
1996-07-02 16:03:47 +00:00
fvdl 2f1b74d9f0 Always call vnode_pager_uncache when removing a file in the server
(same as in sys_unlink()).
1996-07-01 11:16:03 +00:00
fvdl b27bafebd5 We're only handling uio with iovcnt == 1, so don't ever attempt to increment
uio_iov, this will get us into nasty trouble. (Thanks to Matthias Drochner for
tracking this down).

pk 6e8ba625ef Ignore the mountpoint's `v_usecount' in nfs_unmount() if MNT_FORCE is on.
This takes care of two related problems:
	- `umount -f' wouldn't work if someone's working directory is
	  the filesystem root.
	- vfs_unmountall() would complain about a busy `/' on a
	  diskless setup.
1996-06-24 10:26:40 +00:00
cgd d73abf41aa avoid unnecessary checks of m_get/MGET/etc.'s return values. When
they're called with M_WAIT, they are defined to never return NULL.
1996-06-14 22:21:12 +00:00
cgd d9d0cc229c fix two bugs (the latter potentially fatal) in xdr_string_encode():
(1) if length needed was > MCLBYTES, an mbuf would be lost, and
(2) the wrong check was being used to determine if MCLGET succeeded.

fvdl e4145cb406 Align things right in NWDELAYHASH (for the Alpha). This fixes crashes in
the server code. From John Birell.
1996-05-27 11:22:31 +00:00
fvdl 2847784948 * Make mounts with symlinks work (needed for direct mounts with amd). PR #1917
* Never change the NQNFS flag and/or version when just doing an update mount.
  Fixes a problem that made diskless booting impossible under some
  circumstances.
1996-05-23 22:47:27 +00:00
mycroft 49d52c9b1c Pass a proc pointer down to the usrreq and pcbbind functions for PRU_ATTACH, PRU_BIND and
PRU_CONTROL.  The usrreq interface really needs to be split up, but this will have to wait.
Remove SS_PRIV completely.
1996-05-22 13:54:55 +00:00
mycroft 261382c331 Change VOP_UPDATE() semantics:
* Make 2nd and 3rd args timespecs, not timevals.
* Consistently pass a Boolean as the 4th arg (except in LFS).
Also, fix ffs_update() and lfs_update() to actually change the nsec fields.
1996-05-11 18:26:27 +00:00
thorpej 3b8a528094 Changed struct ifnet to have a pointer to the softc of the underlying
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit.  Updated interface to (*if_watchdog)() and (*if_reset)()
to take a struct ifnet *, rather than a unit number.
1996-05-07 02:51:25 +00:00
thorpej b417cc19fe Make this compile again on a SPARC if NFSCLIENT is defined without
NFSSERVER.  (-Wall unused variable lossage)
1996-04-15 20:20:00 +00:00
thorpej ea39811fd8 Make these link in the absense of "options FIFO". 1996-04-03 23:25:36 +00:00
fvdl fa29f1090f Return earlier on error in nfs_statfs. Should fix problem reported by
both mrg and cgd.
1996-03-24 23:58:10 +00:00
fvdl c0d2b279c6 Make sure not to free the reply mbuf twice. Should fix PR #2240 1996-03-20 21:59:56 +00:00
christos 3fac949f8f Fix printf format strings. 1996-03-17 02:38:20 +00:00
fvdl f5e6df1ed0 Disable invalidating of directory offsets cookies. Should fix one or two
directory problems.

XXX There is no clean solution to the cookie/cookieverifier validity mess.
    Together with the disabled strict cookie check, this puts us back at
    what v2 did in this case. Slightly better solution possible by
    consequently storing 64bit cookies in other places too.
1996-03-13 00:44:17 +00:00
fvdl 146f96c2ce Make readdirsize default to rsize if rsize is explicitly specified,
and readdirsize isn't.
1996-03-13 00:38:55 +00:00
jtk 6c62245a7b fix panic "leaf should be empty" on diagnostic kernels when unlinking on
a read-only file system.
1996-03-05 05:30:09 +00:00
jtk 115750720d Do not return whiteout directory entries in NFS readdir replies. (The
NFS protocol doesn't know how to deal with them properly, yet.)
1996-03-02 15:55:52 +00:00
fvdl 52d04f3b3f Make sure to clear B_NEEDCOMMIT in the right spot. Fix 'officially blessed'
by Rick Macklem. Fixes PR kern/2128.
1996-02-29 20:26:16 +00:00
fvdl 3821dd940b Oops. Do previous fix on the right line this time.. (thanks Charles) 1996-02-25 17:47:26 +00:00
fvdl 1f20fc9fc2 Call soreserve() with the right size for receives (from pk). 1996-02-25 15:30:01 +00:00
cgd e98dc62664 Third argument to VOP_PATHCONF is a register_t *, and register_t may be
different than 'int'.  Do the right thing when declaring variables which
are used this way.
1996-02-20 23:45:10 +00:00
fvdl e9788cf246 Fix a missing 'error =' before 'if (error)'. 1996-02-18 14:06:50 +00:00
fvdl 5ac7df1caf Bring in a merge of Rick Macklem's NFSv3 code from Lite2 1996-02-18 11:53:36 +00:00
gwr 04ff35d122 Add stub for nfs_boot_getfh if NETHER==0 1996-02-16 15:18:19 +00:00
gwr b29ca3a272 Do the RPC to bootparamd a little later (just before the mountd call)
so that we do not ask for the "swap" path when swapping on disk.

mycroft c9c8301a91 Fix vop_link, vop_symlink, and vop_remove semantics in several ways:
* Change the argument names to vop_link so they actually make sense.
* Implement vop_link and vop_symlink for all file systems, so they do proper
  cleanup.
* Require the file system to decide whether or not linking and unlinking of
  directories is allowed, and disable it for all current file systems.
(Also, remove the cross-device link check, that was moved into the file
systems some time ago.)

mycroft 59d1cce3ae Don't specify a uid or gid in create operations; let the server fill it in. 1996-01-31 05:13:33 +00:00
mycroft 85f2006f7a Correct some uses of -1 and VNOVAL. 1996-01-31 04:24:35 +00:00
cgd 3e0efb4d89 changes to make this work on systems where pointers & longs are 64 bits.
This is mostly just changes to make the stuff that goes over the wire
use fixed-size types.

ghudson d61f235615 Add cookie support. Stash cookies in the word prior to the end of
each entry, and read them out in nfs_readdir().

Caveat: our current caching method for directory blocks uses the
server offset of the first directory entry as an identifier, so a
Linux emulation getdirentries() will wind up retrieving one block from
the NFS server for each directory entry, unnecessarily thrashing the
cache.  The situation isn't as bad for other emulations.

Instead of getblk(), we need to write a routine to scan each cache
block associated with vp to find a cookie that matches at some
directory entry.  Some later time.
1995-10-14 00:56:07 +00:00
mycroft b12f4a4409 For now, return EINVAL if the client needs cookies. 1995-10-09 11:25:30 +00:00

prototypes into scope.
