of local file systems has been added over time, and at least zfs

xfs, ntfs, ntfs-3g, msdosfs should be added, probably more).

lock experienced contention a number of processes would race to acquire
lock when it was released. This problem resulted in a lot of CPU
load as well as locks being picked up out of order.
Unfortunately, a regression snuck in which allowed multiple threads
to pickup the same lock when -k was not used. This could occur when
multiple processes open a file descriptor to inode X (one process
will be blocked) and the file is unlinked on unlock (thereby removing
the directory entry allow another process to create a new directory
entry for the same file name and lock it).
This changes restores the old algorithm of: wait for the lock, then
acquire lock when we want to unlink the file on exit (specifically
when -k is not used) and keeps the new algorithm for when -k is used,
which yields fairness and improved performance.
Also, update the man page to inform users that if lockf(1) is being
used to facilitate concurrency between a number of processes, it
is recommended that -k be used to reduce CPU load and yeld
fairness with regard to lock ordering.

On 64-bit platforms there was no padding, so the dummy

By elimininating the dummy argument, 64-bit platforms now

general, when support was added to netstat for fetching data using sysctl,
no provision was left for fetching equivalent data from a core dump, and
in fact, netstat would _always_ fetch data from the live kernel using
sysctl even when -M was specified resulting in the user believing they
were getting data from coredumps when they actually weren't. Some specific
changes:
- Add a global 'live' variable that is true if netstat is running against
the live kernel and false if -M has been specified.
- Stop abusing the sysctl flag in the protocol tables to hold the protocol
number. Instead, the protocol is now its own field in the tables, and
it is passed as a separate parameter to the PCB and stat routines rather
than overloading the KVM offset parameter.
- Don't run PCB or stats functions who don't have a namelist offset if we
are being run against a crash dump (!live).
- For the inet and unix PCB routines, we generate the same buffer from KVM
that the sysctl usually generates complete with the header and trailer.
- Don't run bpf stats for !live (before it would just silently always run
live).
- kread() no longer trashes memory when opening the buffer if there is an
error on open and the passed in buffer is smaller than _POSIX2_LINE_MAX.
- The multicast routing code doesn't fallback to kvm on live kernels if
the sysctl fails. Keeping this made the code rather hairy, and netstat
is already tied to the kernel ABI anyway (even when using sysctl's since
things like xinpcb contain an inpcb) so any kernels this is run against
that have the multicast routing stuff should have the sysctls.
- Don't try to dig around in the kernel linker in the netgraph PCB routine
for core dumps.
Other notes:
- sctp's PCB routine only works on live kernels, it looked rather
complicated to generate all the same stuff via KVM. Someone can always
add it later if desired though.
- Fix the ipsec removal bug where N_xxx for IPSEC stats weren't renumbered.
- Use sysctlbyname() everywhere rather than hardcoded mib values.

priorities, etc.) in the NICE field:
Use a combination of pri_native and pri_user instead of pri_level to
guess the original realtime priority. Using pri_level here has been
wrong since 2001/02/12. Using only pri_native here would be correct
if the kernel actually initialized it reasonably. (The kernel exports
its raw td_base_priority as pri_native, but userland mostly wants a
refined base priority). Give up on waiting pri_native to work correctly
and only use it when there is nothing better (for kthreads).
This should reduce printing of bizarre pseudo-nice values. Bizarre
values are still printed if we observe a transient borrowed priority
for a kthread (transient borrowing is the main thing that makes the
raw td_base_priority almost useless in userland), or if there is a
kernel bug. One current kernel bug involves the kernel idprio thread
pagezero permanently changing its priority from PRI_MAX_IDLE (255) to
PUSER (160). Then the bizarre value "ki-6" is printed instead of
"ki31". Here "-6" is PRI_MIN_IDLE - PUSER = -64 truncated to 2
characters. We are observing a transient borrowed priority that has
become permanent due to a bug.

and protocol-independent host mode multicast. The code is written to
accomodate IPv6, IGMPv3 and MLDv2 with only a little additional work.
This change only pertains to FreeBSD's use as a multicast end-station and
does not concern multicast routing; for an IGMPv3/MLDv2 router
implementation, consider the XORP project.
The work is based on Wilbert de Graaf's IGMPv3 code drop for FreeBSD 4.6,
which is available at: http://www.kloosterhof.com/wilbert/igmpv3.html
Summary
* IPv4 multicast socket processing is now moved out of ip_output.c
into a new module, in_mcast.c.
* The in_mcast.c module implements the IPv4 legacy any-source API in
terms of the protocol-independent source-specific API.
* Source filters are lazy allocated as the common case does not use them.
They are part of per inpcb state and are covered by the inpcb lock.
* struct ip_mreqn is now supported to allow applications to specify
multicast joins by interface index in the legacy IPv4 any-source API.
* In UDP, an incoming multicast datagram only requires that the source
port matches the 4-tuple if the socket was already bound by source port.
An unbound socket SHOULD be able to receive multicasts sent from an
ephemeral source port.
* The UDP socket multicast filter mode defaults to exclusive, that is,
sources present in the per-socket list will be blocked from delivery.
* The RFC 3678 userland functions have been added to libc: setsourcefilter,
getsourcefilter, setipv4sourcefilter, getipv4sourcefilter.
* Definitions for IGMPv3 are merged but not yet used.
* struct sockaddr_storage is now referenced from <netinet/in.h>. It
is therefore defined there if not already declared in the same way
as for the C99 types.
* The RFC 1724 hack (specify 0.0.0.0/8 addresses to IP_MULTICAST_IF
which are then interpreted as interface indexes) is now deprecated.
* A patch for the Rhyolite.com routed in the FreeBSD base system
is available in the -net archives. This only affects individuals
running RIPv1 or RIPv2 via point-to-point and/or unnumbered interfaces.
* Make IPv6 detach path similar to IPv4's in code flow; functionally same.
* Bump __FreeBSD_version to 700048; see UPDATING.

There is `lastaddr' set by applies(), which is to notify the `c'

Handling early EOF condition in applies() could look more logical,
but it would effectively revert sed to the unreasonable behaviour
