an alternative program to be used for mounting a file system.
Ideally, all file systems
should be converted to pass string arguments to nmount(), so that
/sbin/mount can handle them. However, certain file systems such as FUSE have
not done this, and want to have their own userland mount programs.
For example, to mount an NTFS file system with the FUSE NTFS driver:
mount -t ntfs -o mountprog=/usr/local/bin/ntfs-3g /dev/acd0 /mnt
or via an fstab entry:
/dev/acd0 /mnt ntfs ro,noauto,mountprog=/usr/local/bin/ntfs-3g 0 0

channel modes:
o usurp 'h' mode flag for half-width channels
o add 'q' mode flag for quarter-width channels
o rewrite rate parameter parsing to handle fractional values
o merge mode loops to eliminate ordering assumptions
o replace 0x80 with IEEE80211_RATE_MCS

space taken by a partition. The offset and size are used to
describe the effective (usable) storage of that partition.
o add missing channel flags for ECM, indoor, and outdoor constraints
o use HT capabilities to short-circuit HT20/HT40 channel construction
o rewrite 1/2 and 1/4 width channel handling yet again; previously
we assumed there was a full-width version of the channel in the
calibration table but that's not always true (e.g. for the Public
Safety Band), now we first check the calibration table for the
exact channel we want then fall back to the heuristics we used before

robust. With these changes fsck is now able to detect and reliably
rebuild corrupted cylinder group maps. The -D option is no longer
necessary as it has been replaced by a prompt asking whether the
corrupted cylinder group should be rebuilt and doing so when requested.
These actions are only offered and taken when running fsck in manual
mode. Corrupted cylinder groups found during preen mode cause the fsck
to fail.
Add the -r option to free up excess unused inodes. Decreasing the
number of preallocated inodes reduces the running time of future
runs of fsck and frees up space that can allocated to files. The -r
option is ignored when running in preen mode.

things, 1/2 and 1/4 width channels are hidden behind the full width
channel; this is needed because they are ordered such that they
appear after in the channel table
o only include 1/2 and 1/4 width channels when they are specified in the
regulatory database description; previously we treated them as if they
were part of the band and blindly added them for 11a/g
o check the channel list returned in the devcaps to identify whether a
device supports 1/2 or 1/4 width channels on a band; this might be
better brought out as a capability bit to avoid filling the channel
list w/ 1/2 and 1/4 width channels but then cards that only support
these channels in a range of frequencies could not be described (though
right now we don't check frequency range only band)
fragments in the file system by fragment (block) number. This new
mode does the necessary arithmetic to generate absolute fragment
numbers rather than than the cg-relative numbers printed in the default
mode.
If -f is passed once, contiguous fragment ranges are collapsed into
an X-Y format as free block lists are currently printed in regular
dumpfs output, but if specified twice, all block numbers are printed
individually, allowing both compact and more script-friendly
representation.
This proves quite handy when attempting to recover deleted data, as it
allows exclusion of non-deleted data from blocks searched.

o change ioctl's that pass channel lists in/out to handle variable-size
arrays instead of a fixed (compile-time) value; we do this in a way
that maintains binary compatibility
o change ifconfig so all channel list data structures are now allocated

Usual moving of code with no changes from ipfw2.c to the
newly created files, and addition of prototypes to ipfw2.h
I have added forward declarations for ipfw_insn_* in ipfw2.h
to avoid a global dependency on ip_fw.h
In this episode:
- introduce a common header with a minimal set of common definitions;
- bring the main() function and options parser in main.c
- rename the main functions with an ipfw_ prefix
No code changes except for the introduction of a global variable,
resvd_set_number, which stores the RESVD_SET value from ip_fw.h
and is used to remove the dependency of main.c from ip_fw.h
(and the subtree of dependencies) for just a single constant.
program name, and ignore that entry. ipfw2.c code instead skips
this entry and starts with options at offset 0, relying on a more
tolerant implementation of the library.
This change fixes the issue by always passing a program name
in the first entry to getopt. The motivation for this change
is to remove a potential compatibility issue should we use
a different getopt() implementation in the future.
No functional changes.

Most entries in the table are probably 15+ years old and largely outdated,

1. separating L2 tables (ARP, NDP) from the L3 routing tables
2. removing as much locking dependencies among these layers as
possible to allow for some parallelism in the search operations
3. simplify the logic in the routing code,
The most notable end result is the obsolescent of the route
cloning (RTF_CLONING) concept, which translated into code reduction
in both IPv4 ARP and IPv6 NDP related modules, and size reduction in
struct rtentry{}. The change in design obsoletes the semantics of
RTF_CLONING, RTF_WASCLONE and RTF_LLINFO routing flags. The userland
applications such as "arp" and "ndp" have been modified to reflect
those changes. The output from "netstat -r" shows only the routing
entries.
Quite a few developers have contributed to this project in the
past: Glebius Smirnoff, Luigi Rizzo, Alessandro Cerri, and
Andre Oppermann. And most recently:
- Kip Macy revised the locking code completely, thus completing
the last piece of the puzzle, Kip has also been conducting
active functional testing
- Sam Leffler has helped me improving/refactoring the code, and
provided valuable reviews
- Julian Elischer setup the perforce tree for me and has helped
me maintaining that branch before the svn conversion
