briggs 33a79483d0 Fix a panic that occurred when trying to traverse a corrupt msdosfs
filesystem.  With this particular corruption, the code in pcbmap()
would compute an offset into an array that was way out of bounds,
so check the bounds before trying to access and return an error if
the offset would be out of bounds.

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.

add quota support to TODO - makes sense only once writing support

jdolecek 62e0ed44c8 Allow separate masks for files and directories. Useful e.g. to turn
the execute bit off for files, but keep search permission for directories.
Change contributed in PR kern/21538 by Pavel Arnost, based on some FreeBSD
patches.
Further manpage changes, and backward-compatibility adjustments done by me.

fvdl d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage,

thorpej d189d63466 Fix problems with the ktrace/lwp changes. 2003-06-29 18:53:52 +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.

darrenr 28c230cff5 More changes for providing lwpid for ktrace (sparc GENERIC built) 2003-06-29 09:56:29 +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.

christos 80ecd573c0 PR/1796: John Kohl: statfs misbehaves under chrooted environments.
- Under chroot it displays only the visible filesystems with appropriate paths.
- The statfs f_mntonname gets adjusted to contain the real path from root.
- While was there, fixed a bug in ext2fs, locking problems with vfs_getfsstat(),
  and factored out some of the vfsop statfs() code to copy_statfs_info(). This
  fixes the problem where some filesystems forgot to set fsid.
- Made coda look more like a normal fs.

jdolecek 1ae0467918 back to passing magic '1' as lock id in smbfs_advlock() - the number
is used to setup a 'PID' for the lock; if a SMB write request is sent
to server, it returns EDEADLK if it doesn't have same PID. since we
use '1' as request PID (see smb_rq_new()), we must use '1' here too,
for now
add a comment what is the ID used for, to avoid similar mistake in future

this partially back off rev 1.5, and makes advisory locking work
on SMB shares mounted from Windows again (sigh)
