fields as discussed in the commit to ip_fw.c:1.186
On top of this, a ton of non functional changes to clean up the code,
write functions to replace sections of code that were replicated
multiple times (e.g. the printing or matching of flags and options),
splitting long sections of inlined code into separate functions,
and the like.
I have tested the code quite a bit, but some typos (using one variable
in place of another) might have escaped.
The "embedded manpage" is a bit inconsistent, but i am leaving fixing
it for later. The current format makes no sense, it is over 40 lines
long and practically unreadable. We can either split it into sections
( ipfw -h options , ipfw -h pipe , ipfw -h queue ...)
or remove it altogether and refer to the manpage.
+ setting a bandwidth too large for a pipe (above 2Gbit/s) could
cause the internal representation (which is int) to wrap to a
negative number, causing an infinite loop in the kernel;
+ (see PR bin/35628): when configuring RED parameters for a queue,
the values are not passed to the kernel resulting in panics at
runtime (part of the problem here is also that the kernel does
not check for valid parameters being passed, but this will be
fixed in a separate commit).
These are both critical fixes which need to be merged into 4.6-RELEASE.

o Implement -c (clear) to clear previously kept headers (note that
dumps not cleared will remain until -c is used),
o Implement -f (force) to allow re-saving a previously saved dump,
o Implement -k (keep) and make clearing the dump header the default,
o Implement -v (verbose) and make most output conditional upon it,
o Emit minimal output for the non-verbose case with the assumption
that savecore is run mostly from within /etc/rc,
o Update usage message to reflect what is and what's not,
o mark -d as obsolete.
Low-level changes:
o Rename devname to device, for devname mirrors a global declaration
and GCC 3.x warns about it,
o Open the dump device R/W for clear and !keep to work,
o Reorder the locals of DoFile according to style(9),
o Remove newlines from strings passed to warn* and err*,
o Use stat(2) to check if a dump has been saved before,
o Truncate existing core and info files to support force,
o First check for the magic and the version before we complain about
parity errors. This prevents emitting parity error messages when
there's no dump,
o Keep track of the number of headers found and the number of headers
saved to support the minimal output,
o Close files we opened in DoFile. Not critical, but cleaner.

that might have changed, then did a byte-by-byte comparison with
the alternate. If any unused fields got used, they had to be added
to the exception list. Such changes caused too many false alarms.
So, I have changed the comparison algorithm to compare a selected
set of fields that are not expected to change. This new algorithm
causes far fewer false hits and still does a good job of detecting
problems when they have really occurred. In particular, this change
should ease the transition to kernels supporting UFS2 which make
some significant changes to the superblock.

Commandline compatible with the previous savecore unless you specify
any options, none of them are implemented (yet).
Scans all devices marked "dump" or "swap" for dump header signatures
and saves dumps off under a name which is a MD5 hash of the header
information. This should give unique filenames. A *.info file contains
ascii version of the header information.
Caveats:
The new savecore program is not complete in the sense that it emulates
enough of the old savecores features to do the job, but implements none
of the options yet.
I would appreciate if a userland hacker could help me out getting savecore
to do what we want it to do from a users point of view, compression,
email-notification, space reservation etc etc. (send me email if
you are interested).
Currently, savecore will scan all devices marked as "swap" or "dump" in
/etc/fstab _or_ any devices specified on the command-line.
All architectures but i386 lack an implementation of dumpsys(), but
looking at the i386 version it should be trivial for anybody familiar
with the platform(s) to provide this function.
Documentation is quite sparse at this time, more to come.

machdep.guessed_bootdev, and add code to sysctl to parse its value
and give a (not necessarily correct) name to the device we booted
from (the main motivation for this code is to use the info in the
PicoBSD boot scripts, and the impact on the kernel is minimal).
NOTE: the information available in bootdev is not always reliable,
so you should not trust it too much. The parsing code is the same
as in boot2.c, and cannot cover all cases -- as it is, it seems to
work fine with floppies and IDE disks recognised by the BIOS. It
_should_ work as well with SCSI disks recognised by the BIOS.
Booting from a CDROM in floppy emulation will return /dev/fd0 (because
this is what the BIOS tells us).
Booting off the network (e.g. with etherboot) leaves bootdev unset so
the value will be printed as "invalid (0xffffffff)".
Finally, this feature might go away at some point, hopefully when we
have a more reliable way to get the same information.

modifying the source code and not to use __h_errno_set.
