- g_lcm() - calculates Least Common Multiple of two given values,
it is helpful when we need to find sector size for provider
which is based on disks with different sector size;
- g_get_mediasize() - returns media size of given provider;
- g_get_sectorsize() - returns sector size of given provider;
Those function aren't used now, but are used by geom_mirror which will be
committed soon.
routed should be able to specify multicast memberships to be added by
interface index. This should fix the unnumbered / point-to-point case
for RIPv2.

. Implement option -c, all partition sizes will be calculated
in cylinders as opposed to sectors. Since the Sun label is
inherently cylinder-based, this makes the job a little easier.
. Implement option -h, print the label in `human readable'
size/offset format.
. Implement SVR4-compatible VTOC-style elements. They are
fully optional, defaulting to the current behaviour where no
VTOC-style table will be written to disk. However, if
desired, the full functionality of the partitioning menu of
Solaris' format(1m) is now offered (and even more).
. When editing the label, do not loop around edit_label() where
a new template file is generated for each turn, this used to
be annoying in that any possible syntax error caused a
complaint, but then the template was created anew, so the
user had to perform all their editing again. Rather loop
inside edit_label(), similar to bsdlabel(8), so in case of
errors, the user will be presented their previous template
file again.
. If VTOC-style elements are present, the overlap checks are
made less stringent. Overlaps will still be warned about,
but overlaps of `unmountable' partitions against other ones
are no longer fatal. That way, e. g. VxVM encapsulated
disk labels can be fully edited in FreeBSD (but not in
Solaris ;-).
. In print_label(), generate the editing hints only if the -e
flag is in effect. Additionally, print a hint about the
total number of sectors in the (hardware) medium.
. When editing a label, allow for changing the geometry
emulation (and textual name) by modifying the "text:" line
on top. That way, a more effective emulation can be
chosen.
. When editing/reading a label, additionally allow for the
suffixes `s' (512-byte sectors), and `c' (cylinders) in the
partition size field.
. Finally, turn the stub man page into something that really
explains the entire thing.
Print the ETA of dump being finished, rather than a cryptic delta
time. Also, if we have written more blocks than the tapesize, assume
that we are 99.99% done and that we'll be finished 'soon'.

GEOM classes. It works by loading a shared library via dlopen(3) mechanism
with class-specific code, it is also responsible for communicating with
GEOM via libgeom(3).
Per-class shared libraries are going to be stored in /lib/geom/ directory.
It provides also few standard commands like 'list', 'load' and 'unload'
for existing classes which aren't aware of geom(8).
More info will be send on freebsd-current@ mailing list.

shuffles the timing and sleep calls in bgfsck from:
sleep timer_on io timer_off io io io io io io io
to
sleep io io io io io io io timer_on io timer_off
The original method basically guaranteed that the timed I/O included a
disk seek every time, which made bgfsck sleep for much longer than
necessary.

root is allowed to create raw sockets, then they will be able to create
routing sockets, too. However prison-root is not able to manipulate
routing tables. So when route(8) attempts to write to a routing
socket and recieves EPERM from the kernel, exit rather than moving
on with execution.

violate POLA a little less by not requiring exactly two spaces in front
of the entry (and silently discarding any non-matching entry). We now
recognize anything starting with a letter followed by a colon as the
first non-space chars as a partition entry.

only needed to satisfy leakage of kernel interfaces to userland and
namespace bugs in those interfaces...
This little thing can cause a deadlock, because taste mechanism start
to work after creation of ggate provider and I/O requests are sent from
other classes from the g_event thread, so number of pending events isn't 0.
Now ggatec(8) start second handshake and ggated(8) is trying to open
GEOM provider (for example md(4)) and it can't, because it hangs on
g_waitidle() in g_dev_open(). g_waitidle() cannot finish because
there is a pending read on event queue, and this read can't be
finished, because ggated(8) can't open target device.
GEOM Gate will recover from this deadlock, because requests will
timeout, but it of course isn't the best solution and I don't know
better one for now, so we should avoid opening GEOM providers while
there are pending requests in event queue.

This we don't support. So, before gpt(8) can be used on a big-endian
machine, it has to deal with the endianness.

Also try again for deleting routes if things fail. We've seen

This fixes it. It will whine but it will do the work.

libufs, which only works for Charlie root.
This change reverts the introduction of libufs and moves the
check into the kernel. Since the f_fstypename is the same
for both ufs and ufs2, we check fs_magic for presence of
ufs2 and copy "ufs2" explicitly instead.

source address of a packet exists in the routing table. The
default route is ignored because it would match everything and
render the check pointless.
This option is very useful for routers with a complete view of
the Internet (BGP) in the routing table to reject packets with
spoofed or unrouteable source addresses.
