The index() and rindex() functions were marked LEGACY in the 2001
revision of POSIX and were subsequently removed from the 2008 revision.
The strchr() and strrchr() functions are part of the C standard.
This makes the source code a lot more consistent, as most of these C
files also call into other str*() routines. In fact, about a dozen
already perform strchr() calls.
writing label into a file image. The most common use - putting disklabel
into ISO file. Before this change the label would always go to
the offset 512, while geom_part code expects it to be in the 1st
sector (i.e. 2048 incase of ISO). BSD disklabels provide good and
lightweight way to logically split livecds. It is non-intrusive as
far as ISO9660 goes (both boot-wise and metadata-wise) and
completely transparent to anything but BSD, so you can have
BSD-specific area appended after regular ISO.
And with a little bit of GEOM trickery you can do even more
interesting stuff with it.
For example we make "hybrid" bootable CDs using this method.
We create bootable ISO with kernel and such and append UFS
image compressed with UZIP and it works like a charm. We put
label based on the offsef of the BSD part into the ISO. The kernel
boots off normal ISO9660 part, tastes label attaches it,
tastes UZIP, attaches it and finally mounts UFS using GEOM_LABEL.
This provides much better way of eliminating waste than doing
"crunched" build.

In the original Domain Search option patch, an invalid option value
would cause the whole lease to be rejected. However, DHCP servers who
emit such an invalid value are more common than I thought. With this new
patch, just the option is rejected, not the entire lease.

from scratch, copying needed functionality from the old implemenation
on demand, with a thorough review of all code. The main change is that
interface layer has been removed from the CARP. Now redundant addresses
are configured exactly on the interfaces, they run on.
The CARP configuration itself is, as before, configured and read via
SIOCSVH/SIOCGVH ioctls. A new prefix created with SIOCAIFADDR or
SIOCAIFADDR_IN6 may now be configured to a particular virtual host id,
which makes the prefix redundant.
ifconfig(8) semantics has been changed too: now one doesn't need
to clone carpXX interface, he/she should directly configure a vhid
on a Ethernet interface.
To supply vhid data from the kernel to an application the getifaddrs(8)
function had been changed to pass ifam_data with each address. [1]
The new implementation definitely closes all PRs related to carp(4)
being an interface, and may close several others. It also allows
to run a single redundant IP per interface.
Big thanks to Bjoern Zeeb for his help with inet6 part of patch, for
idea on using ifam_data and for several rounds of reviewing!

In the r228313 this behavior was fixed, and since dhclient-script
got broken.
I'm not sure this fix is a perfect one, it just changes
dhclient-script to set 0.0.0.0/255.0.0.0 explicitly.

This tool only consists of a single C file, so we can simply mark
everything except main() static. This seems to shave off about 8% of the
binary size.
The global variables and functions provided by rcorder.c are not used in
the other C files, as the other C files only provide memory allocation
and hash functions. This reduces the binary size by 10%.
The "domain-search" option (option 119) allows a DHCP server to publish
a list of implicit domain suffixes used during name lookup. This option
is described in RFC 3397.
For instance, if the domain-search option says:
".example.org .example.com"
and one wants to resolve "foobar", the resolver will try:
1. "foobar.example.org"
2. "foobar.example.com"
The file /etc/resolv.conf is updated with a "search" directive if the
DHCP server provides "domain-search".
A regression test suite is included in this patch under
tools/regression/sbin/dhclient.

Firmware can be reprogrammed on devices from Hitachi, HP, IBM, Plextor,
Quantum, and Seagate. At least one device from each manufacturer has
been tested with some version of this code, and it has been used to
update thousands of drives so far.
The man page suggests having a backup of the drive's data, and the
operation must be confirmed, either interactively or on the command
line. (This is the same as the confirmation on the format command.)
This work is largely derived from fwprog.c by Andre Albsmeier.

- Improved locking and destruction process to fix crashes.
- Improved "automatic" configuration method to make it consistent and safe
by reading metadata back from all specified paths after writing to one.
- Added provider size check to reduce chance of ordering conflict with
other GEOM classes.
- Added "manual" configuration method without using on-disk metadata.
- Added "add" and "remove" commands to allow manage paths manually.
- Failed paths are no longer dropped from geom, but only marked as FAIL
and excluded from I/O operations.
- Automatically restore failed paths when all others paths are marked
as failed, for example, because of device-caused (not transport) errors.
- Added "fail" and "restore" commands to manually control FAIL flag.
- geom is now destroyed on last path disconnection.
- Added optional Active/Active mode support. Unlike Active/Passive
mode, load evenly distributed between all working paths. If supported by
the device, it allows to significantly improve performance, utilizing
bandwidth of all paths. It is controlled by -A option during creation.
Disabled by default now.
- Improved `status` and `list` commands output.
