christos 3c07a14a75 Separate assigments of tv_sec and tv_nsec since tv_sec is a time_t (int on 
the alpha) and tv_nsec is a long.

enami acd4cefee0 In the function vattr_null(), assign each member individually 
to prevent unintended conversion due to different sign and size.

thorpej a2721a0f1b In vfs_shutdown(), do the "sync and wait for it to finish" _before_ 
unmounting all of the file systems.  If we encounter a condition where
all of the dirty buffers could not flush, then don't unmount file systems,
since it might be likely to wedge.

fvdl 4ad51c2811 Allow multiple export requests for a filesystem, host pair if the flags and 
anon cred are the same. Should probably be handled better in the mountd,
but this will do for now. Fixes PR 469, submitted Sept 1994 by
a certain "Jason R. Thorpe".. ;-)
 1997-07-20 23:31:32 +00:00
fvdl 4702f17abc Add functions to set/reset the info about the publicly exported 
(WebNFS) filesystem. At first glance this should go into the
NFS code, but all the other export code is here as well.

cgd 21bbd49bf2 in vfs_shutdown(), print "syncing disks... " before dropping to spl0(), 
so that if the drop to spl0() causes another panic (e.g. because there's
still some fatal hardware interrupt that's pending) we'll know that we
dropped IPL to sync the disks.

mycroft 06fb68217b Oops; fix reversed test for VDIR. 1997-05-08 16:34:54 +00:00
mycroft e3f99a9397 Pass the vnode type to vaccess(), and use it when checking VEXEC. Make sure 
that the mode bits passed to vaccess() and returned by foo_getattr() contain
only permission bits.
 1997-05-08 16:19:43 +00:00
mycroft 8f5978a181 GC VS[UG]ID and VSVTX, and add a new VLOOKUP, since the semantics are now 
different from VEXEC.

mycroft c32418bf82 Fix error in vfs_hang_addrlist() that caused file systems to be exported 
to more subnets than expected when using netmasks.  From Mike Hibler.

mycroft 5e62a0725b Change previous test slightly. 1997-04-23 20:19:45 +00:00
mycroft b34794e10f Do not return success when checking for execute permission by super-user and no 
execute bits are set.  Also, this test is no longer needed in execve(2).
 1997-04-23 20:18:16 +00:00
mycroft 6911ff7d13 Fix two performance issues: 
* When a delayed write buffer falls off the LRU queue, arrange for it to go on
  the AGE queue after being flushed out to disk.
* When a delayed write buffer is synced, leave it in its relative position in
  the LRU queue.

kleink 5ec0772a62 In checkalias(), initialize the speclockf structure member invented 
with the specfs advisory locking support; this could cause a panic.
 1997-04-03 23:15:52 +00:00
fvdl 501f1a3eb9 Do previous change properly (pasto; should have been inside the loop). 1997-02-23 00:07:18 +00:00
fvdl 0538233e2c Implement changes to make fix for NQNFS and MFS unmounting (race conditions) 
work. Not quite as good as with the Lite2 merges, but it'll do until then.

* dounmount() expects to be called with the mountpoint marked busy
* all callers of dounmount() thus make the call themselves
* if a filesystem was being unmounted, and we're woken up in vfs_busy(),
  don't reference the mountpoint struct pointer, as it has very probably
  been freed.

thorpej 2ca27c5550 Garbage-collect "argdev". 1997-01-31 19:10:27 +00:00
thorpej 68de7ca719 - Implement vfs_mountroot(). This function is called my main() to 
mount the root file system.  If the operator specified the root
  file system type in the kernel configuration file, attempt to
  mount that file system type on the root device.  If the root
  file system type was wildcarded (or unspecified), try all of
  the file systems statically built into the kernel until one
  succeeds.  If no file systems succeed, return an error.  The
  system will recover from this condition.
- Implement vfs_getopsbyname().  This function returns the file
  system ops vector given a file system name.

christos 60d201973e printf -> kprintf, sprintf -> ksprintf 1996-10-10 22:46:11 +00:00
cgd 60b9a20b61 initialize vnode_free_list and mountlist at compile time with the new 
queue.h list/queue head initializer macros.  mountlist was converted so
that panics (or other reboots) early on in kernel startup don't cause
sys_sync() to croak.  vnode_free_list was converted because it was nearby.

mycroft 9a4505cb89 Close routines take file flags, not I/O flags. Fix two incorrect usages. 1995-07-02 18:13:02 +00:00
jtc 95ded74f58 Moved egid credential from cr_groups[0] to new field cr_gid. POSIX.1 
requires that sgid executables and the setuid() syscall *not* change
the supplemental group list.
