f712e70aee expbackq() was incorrectly backing up a temporary buffer when removing \n 
from the end of output of commands inside $(...) substitutions.
If the program output is n*128+1 bytes long (ending in a \n) then the code
checks buf[-1] for another \n - looking an uninitialised stack.
On a big-endian system an integer of value 10 will satisfy this (unlikely
on little endian) and can happen depending on the last code path to use
a lot of stack!
This caused the problem with newvers.sh on sparc64 after ', 2005' was
added to the date list.

d980bf3418 Keep track of the length of the gnu long name/link hack, so that 
we can append to it. Modify the code so that file_write is re-entrant,
even in the gnu long name/link hack.

The old code assumed that the buffer already contained the necessary
blocks to satisfy the read file request that contained the long
filename. This is not always the case, specially when we are dealing
with pipes which do shorter reads, thus having more probability
that a long file name will fall across a buffer boundary.

To reproduce, create a tar archive with a lot of gnu-long-names
(pkgsrc/devel/libsigc++2 is a good example), do a tar -tf to get
a list of filenames, compress it and do a tar -tzf to get another
list of the filenames. Notice that the two lists differ.

1ccdf5daeb Make "set -e" once again provide the behavior documented in the man page, 
which was unnecessarily changed in revision 1.50 while fixing other bugs.
That is, exit the shell if the last command in a || or && compound statement
is not short-circuited, and exits with a false status.  I.e., the following
will cause the shell to exit:

  set -e
  false || false

While this is not the prescribed behavior in SUSv3, it is what our man page
documents, and it is what all of the following implementations do:

  NetBSD /bin/ksh (pdksh)
  bash
  zsh
  Solaris 9 /bin/sh
  Solaris 9 /usr/xpg4/bin/sh
  Solaris 9 /usr/bin/ksh

b2f782612f Completely rework how tools/compat is done. Purge all uses/references to 
_NETBSD_SOURCE as this makes cross building from older/newer versions of
NetBSD harder, not easier (and also makes the resulting tools 'different')

Wrap all required code with the inclusion of nbtool_config.h, attempt to
only use POSIX code in all places (or when reasonable test w. configure and
provide definitions: ala u_int, etc).

Reviewed by lukem. Tested on FreeBSD 4.9, Redhat Linux ES3, NetBSD 1.6.2 x86
NetBSD current (x86 and amd64) and Solaris 9.

0deda9612a PR/25934: Dieter Baron: hard links with long names still fail. 
As mentioned in the previous commit, the switch statement in the longlink()
needed simplification and it was a bit incorrect. Only depend on the passed
type to determine what kind of gnu longlink to produce. Don't try to deduce
it from the archive file type.

8c21bc6224 Add ffs internal snapshots. Written by Marshall Kirk McKusick for FreeBSD. 
- Not enabled by default. Needs kernel option FFS_SNAPSHOT.
- Change parameters of ffs_blkfree.
- Let the copy-on-write functions return an error so spec_strategy
    may fail if the copy-on-write fails.
- Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock.
- Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer.
- Add a function ffs_checkfreefile needed for snapshot creation.
- Add special handling of snapshot files:
    Snapshots may not be opened for writing and the attributes are read-only.
    Use the mtime as the time this snapshot was taken.
    Deny mtime updates for snapshot files.
- Add function transferlockers to transfer any waiting processes from
  one lock to another.
- Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through
  a vnode.
- Add snapshot support to ls, fsck_ffs and dump.

It creates directory nodes without the 'd' bit set, so that pax thinks
they are files and does the temporary name and dance with them. Added

revision of the standard.  To quote the manual page:

     The -P option attempts to conform to U.S. DoD 5220-22.M, "National Indus-
     trial Security Program Operating Manual" ("NISPOM") as updated by Change
     2 and the July 23, 2003 "Clearing & Sanitization Matrix".  However,
     unlike earlier revisions of NISPOM, the 2003 matrix imposes requirements
     which make it clear that the standard does not and can not apply to the
     erasure of individual files, in particular requirements relating to spare
     sector management for an entire magnetic disk.  Because these
     requirements are not met, the -P option does not conform to the standard.

This also makes the -P option a *lot* more expensive than it used to be.
It used to overwrite with 0xff, overwrite with 0x00, overwrite with 0xff,
with an fsync after each write.  Now it overwrites with a random character,
overwrites with 0xff, overwrites with 0x00, reads to validate the 0x00
overwrite, then overwrites with random data -- calling sync() after every
operation in an attempt to force seeks that will clear the data from the
cache of disks that lie about whether data has been committed to the
platters.  Also, the file's opened with O_SYNC|O_RSYNC to cause metadata
updates on every read/write, which should cause still more seeks.

This is better than it used to be, but it's by no means adequate if you
have data you really don't want read by an adversary who can pull the
disk apart.

b9173dc41c Rewrite the loop in printflg(): if passing -Z to pax with syntax errors 
(like executing "pax -Z" by itself), this caused a shr of 32 bits, which is
undefined behavior (C99) if the variable is 32 bits wide, too.  Also solves
a problem where the flgch array could be indexed out of bounds.

Thanks to uwe@ and lha@ for their suggestions... I just found the bug :p

375e81b270 Some file systems, like FAT, have no inodes in the ffs sense and don't 
run out of inodes. df -i was saying, however, that such file systems
had 100% of their inodes in use, which would do things like trigger
alarms in scripts looking for file systems that have run out.

Instead, say 0% are in use, which although not strictly true is at
least less wrong, fixes scripts and is less worrying in nightly reports.
