yamt cc716087b0 - tweak lfs_update_single()'s prototype so that it can be used by
roll-forward code.
- reduce code duplication using the above in update_meta()
  this also fixes fragment accounting.

- related assertions.

yamt cd2445d8d3 more assertion about file truncation to zero. 2003-11-07 14:48:28 +00:00
hannken 2ef662a69e Clean up the usage of vn_start_write(). At least one occurence clobbered
previous error conditions.
If "(flags & (V_WAIT|V_PCATCH)) == V_WAIT" the return value is always zero.
Ignore the return value in these cases.

lukem 171d653219 Overhaul how `build.sh tools' are used:
*	Rename "config.h" to "nbtool_config.h" and
	HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
	This makes in more obvious in the source when we're using
	tools/compat/config.h versus "standard autoconf" config.h

    *	Consistently move the inclusion of nbtool_config.h to before
    	<sys/cdefs.h> so that the former can provide __RCSID() (et al),
    	and there's no need to protect those macros any more.

These changes should make it easier to "tool-ify" a program by adding:
	#if HAVE_NBTOOL_CONFIG_H
	#include "nbtool_config.h"
	#endif
to the top of the source files (for the general case).

kleink cceefb77ec Remove the present incarnation of FSYNC_DATAONLY use from ffs_fsync() and
ffs_full_fsync(); while it is supposed to hint that the update of _file_
metadata (as in timestamps et al.) may be omitted it doesn't mean the
same for _filesystem_ metadata.

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.

dbj 5c09d20130 Declare fs_old_flags and fs_flags as unsigned.
This fixes a bug introduced in revision 1.120 of ffs_vfsops dated 2003/09/13
which results in fs_flags having a value of 0x7fffff00 when a superblock
is updated to use the new layout.

yamt 61d5d4362b fix a bug of lfs.
genfs_getpages() can read in more blocks than it should due to faked filesize
of lfs_gop_size().  it's a security problem and it makes gcc3 "internal error"

to fix this,
- in genfs_getpages(), always calculate diskeof and memeof separately
  so that filesystems (in this case, lfs) can use different strategies
  for them.
- introduce GOP_SIZE_MEM flag and use it to request in-core filesize.
  (it was an intention of GOP_SIZE_READ,
  but after the above change _READ is not a straightforward name)

after this, no one uses GOP_SIZE_{READ,WRITE} anymore but leave them for now.

to avoid compat problems with old ffsv1 by reuse of the old FS_SWAPPED
value for FS_FLAGS_UPDATED, and use of new, larger fields:
- Don't use FS_FLAGS_UPDATED to see if we need to update new fields from
  old fields in ffsv1 case.
- when writing back the superblock, copy back the flags to the old location
  if only old flags are set (FS_FLAGS_UPDATED won't be set in this case)
  in ffsv1 case.
