get hung in nfs_reconnect() because they do not have the proper
privilages to bind to a socket, by adding a struct proc * argument
to sobind() (and the *_usrreq() routines, and finally in{6}_pcbbind)
and do the sobind() with proc0 in nfs_connect.

for pf(4) diverted packets; based on patch by Scot Loach; ok beck@
|
|
The option allows a socket to be bound to addresses which are not
local to the machine. In order to receive packets for these addresses
SO_BINDANY needs to be combined with matching outgoing pf(4) divert
rules, see pf.conf(5).

and the one route with the lowest number wins. This will be used by the
routing daemons to resolve the synchronisations issue in case of conflicts.
The nasty bits of this are in the multipath code. If no priority is specified
the kernel will choose an appropriate priority.
Looked at by a few people at n2k8 code is much older

simple on/off, allowing more control over how verbose the logging is.
This also allows you to do a further level of filtering in syslog.conf
if you need to.
Also add logging of state changes, inspired by diff provided by
Brian A. Seklecki in PR 5513. These messages are logged by default.

get a timestamp of when the datagram was accepted (by udp(4), for
example) rather than having to take a timestamp with gettimeofday(2)
when recv(2) returns - possibly several hundreds of microseconds later.
May be of use to those interested in precision network timing schemes
or QoS for media applications. Tested on alpha, amd64, i386 and sparc64.

it by reading the queues head pointer. if that pointer is not null
then it takes splnet and dequeues a packet for handling. this is
bad because the ifqueue head is modified at splnet and the sofnet
handlers read it without holding splnet.
this removes that check of the head pointer and simply checks if
the dequeue gave us a packet or not before proceeding.
found while reading mpls code.

crc in addition to the existing "oneshot" mode and use them to replace
ieee80211_crc_update() with the new ether_crc32_le_update(). Saves 1k
kernel bss + some code.
Mark the new ether_crc32_[lb]e_update functions as __pure for a
~25x speedup (on my i386 at least).

in the range 0 <= x < upper_bound
Please use this new API instead of "arc4random() % upper_bound", as it
avoids the "modulo bias" that favours small results when upper_bound is
not a power of two.

shuffle. Upon allocation, swap-permute the new value to a random slot in
the 0..32K-1 th entry of the buffer as we move forward, ensuring randomness
but also satisfying the non-repeating property we need. Also avoid the value
of 0, since IP ID's of 0 are special. Inspired by Dillon's implementation.
We believe this is easier to read though, initializes with less bias, handles
the ID of 0 properly, and wins speed tests.
Thanks a lot to mcbride and djm for doing a bunch of statistical and speed
analysis, and comments from nordin

Instead of using the same IP on multiple interfaces, carp has to be
configured with the new "carpnodes" and "balancing" options.
# ifconfig carp0 carpnodes 1:0,2:100,3:100 balancing ip carpdev sis0 192.168.5.50
Please note, that this is a flag day for anyone using carp balancing.
You'll need to adjust your configuration accordingly.
Addititionally this diff adds IPv6 NDP balancing support.

IPv4 interface address similar to arp_ifinit(). The main difference is
that we do not send out a gracious arp as the carp(4) is not ready to send
at that moment. This will make backup interface show up like the master ones.

that is kept in a list per carp interface. This is the huge first
step necessary to make carp load balancing nice and easy. One carp
interface can now contain up to 32 virtual host instances.
This doesn't do anything useful yet, but here is how an ifconfig
for multiple entries now looks like:
# ifconfig carp2 carpnodes 5:0,6:100 192.168.5.88
carp2: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500

It is unlikely we will ever get a working replay protection,
so better keep it simple and robust.
The cookie allows us to detect our own advertisements,
thus it is now easy to deal with network loops and
non-simplex interfaces.
Zero feedback by the people who wanted this fixed.
