- avoid race conditions by having seqno in ioctl
- better uid/gid tracking
- "replace" policy to replace args
- less diffs, as many of local changes were fed back to openbsd already
due to the 1st item, it was impossible for us to provide backward-compatibility
(new kernel + old bin/systrace won't work). upgrade both.
IEEE 1003.1-2001 (where applicable) and other systems, by follwoing symlinks
on the command line and changing their targets' modes/ownership/flags, rather
than ignoring them.
This fixes PR standards/563 (at last).
process and "parent" process is more conducive to policy generation.
Previously, tracing of a given program worked something like this:
fork()
if (child)
execprogram()
else
dotracing()
That means that if you "systrace -a named", named would fork and
background itself, but you would never get your prompt back because
systrace didn't exit. Now it works like this:
fork()
if (interactive)
if (child)
execprogram()
else
dotracing()
else
if (parent)
execprogram()
else
fork()
if (parent)
exit(0)
setsid()
dotracing()
This makes it *much* easier to do automated policy generation for
tasks run from rc.d. Or, for that matter, makes it much easier to use
systrace with tasks run from rc.d.

This caused pax -M on sparc64 to generate corrupt tar files.

* Don't -I/sys -- that breaks cross-building. Instead, use relative
pathnames in netbsd-syscalls.c, similar to what kdump does.
* No need to explicitly CLEANFILES the generated lex/yacc results.
* No need to link against libl and liby.

- Put a space after the C language keyword ``switch''.
- Put an empty line if a function doesn't have local variable.
- Use do { } while (/*CONSTCOND*/ 0) instead of { } to protect a multi

Unfortunately the shell assumed that it could do all process group
handling ioctls to fd=2, but this is not correct. Jobs that redirected
fd=2 would be unable to perform the ioctls and silently fail since
the error reporting channel is fd=2... Instead open /dev/tty set
it to close on exec, and use that instead (like all other shells
do). We don't handle the case where the OS does not provide FD_CLOEXEC
or FIOCLEX, because I am lazy.
While I am there:
- Simplify the code by defining functions for tc{g,s}pgrp when OLD_TTY_DRIVER
is defined.
- make sure that 'sh &' works by stopping itself. Don't kill the shell's
process group, kill the shell itself.

sign extension bugs on LP64 systems and partly takes care of PR 15677.
We now print this values as negative seconds - still wrong, but that
probably is due to the simple way this values are acumulated in the
scheduler, causing negative times when ntpd steps time backwards.

This does not affect the -G and -U options, which always use the

- Add strsuftoull(), which parses a number into a u_longlong_t, with
multiplication support, and support for 'g' (GB) and 't' (TB) suffices.
If an error occurs, print to stderr and exit.

- Add strsuftoullx(), which acts as per strsuftoull() but returns the

- Remove (now) unnecessary argument validation
- Remove unused {f,p,s,t}_stats fields in struct IO

alias expansion inside the switch as appropriate. This is achieved by a
flag noalias which is turned on and off in as we parse. In the following
example [1] and [0] indicate the value of noalias.

FreeBSD does:

files on standard input as an mtree(8) `specfile' specification, and
write or copy only those items in the specfile.
If the file exists in the underlying file system, its permissions and
modification time will be used unless specifically overridden by the
specfile. An error will be raised if the type of entry in the specfile
conflicts with that of an existing file.
Otherwise, it is necessary to specify at least the following parameters
in the specfile: type, mode, gname or gid, and uname or uid, device
(in the case of block or character devices), and link (in the case of
symbolic links). If time isn't provided, the current time will be used.
leaving the ansi stuff)
- use longlong_t instead of quad_t (etc), and rename *uqd*() -> *ull*()
- clean up the NET2_STAT stuff similar to ftpd; provide #defines and
macros which select which cast to use, etc
- clean up the NET2_FTS and NET2_REGEX #define use
- fix bug where the 'clear' flag was set outside of main loop, so
"dump,uchg,arch" on a file with flags would clear all the bits
(because "dump" sets 'clear'). noted in FreeBSD PR 10071, and fix
obtained from FreeBSD.
- enforce right-most priority on arguments by clearing the appropriate
bit in the opposite set; if a string of "nouchg,uchg" is given,
chflags(8) would clear uchg because it applies the "set" bits before
clearing the "clear" bits. now, "uchg" sets UF_IMMUTABLE in setp
and also resets it in clrp, solving this problem
- constify second arg (the `default' arg)

Make sure that each va_start has one and only one matching va_end,
especially in error cases.
If the va_list is used multiple times, do multiple va_starts/va_ends.
If a function gets va_list as argument, don't let it use va_end (since
it's the callers responsibility).

Change the add/subtract overflow checks to use an unsigned to do the op

Make multiply shortcut on either right or left being 0.
Make multiply's overflow test not fail on simple cases like 1 * -1
Make the multiple overflow test pass all the regress tests.

Break the arithemtic operators into 2 classes (+- are lower than */%)
Restructure the arithmetic code into a function either class above can call.
Finally, add a whole suite of regression tests (checked in separately) which

- trap now accepts signal names and signal numbers
e.g. INT, SIGINT, 2
- added option -l that outputs a list of valid signals
- added signal EXIT to list of valid signals
- a `-' in the action part will reset specified signal to their
default behaviour
- changed standard output format to make it suitable as an input
to another shell that achieves the same trapping results
