Keyword substitution: kv
Default branch: MAIN

Add sysctl entry to control to send routing message for RTM_DYNAMIC.

Some routing daemons require such routing message to keep coherency.

If we want to let kernel send such message, set net.inet.icmp.dynamic_rt_msg=1
for IPv4, net.inet6.icmp6.dynamic_rt_msg=1 for IPv6.
Default(=0) is the same as before, that is, not send such routing message.

Resolve a couple of conflicts (result of the uimin/uimax changes)

- Cleanup for dynamic sysctl:
  - Remove unused *_NAMES macros for sysctl.
  - Remove unused *_MAXID for sysctls.
- Move CTL_MACHDEP sysctl definitions for m68k into m68k/include/cpu.h and
  use them on all m68k machines.

put the histograms last and make them autosize (breaks compat with netstat).

PR/42243: Yasuoka Masahiko: Add "net.inet.icmp.bmcastecho" sysctl support,
to disable icmp replies to the broadcast address.

Sync with HEAD.

Make IP, TCP, UDP, and ICMP statistics per-CPU.  The stats are collated
when the user requests them via sysctl.

Change ICMP stats from a structure to an array of uint64_t's.

Note: This is ABI-compatible with the old icmpstat structure; old netstat
binaries will continue to work properly.

Changes to allow the IPv4 and IPv6 layers to align headers themseves,
as necessary:
* Implement a new mbuf utility routine, m_copyup(), is is like
  m_pullup(), except that it always prepends and copies, rather
  than only doing so if the desired length is larger than m->m_len.
  m_copyup() also allows an offset into the destination mbuf, which
  allows space for packet headers, in the forwarding case.
* Add *_HDR_ALIGNED_P() macros for IP, IPv6, ICMP, and IGMP.  These
  macros expand to 1 if __NO_STRICT_ALIGNMENT is defined, so that
  architectures which do not have strict alignment constraints don't
  pay for the test or visit the new align-if-needed path.
* Use the new macros to check if a header needs to be aligned, or to
  assert that it already is, as appropriate.

Note: This code is still somewhat experimental.  However, the new
code path won't be visited if individual device drivers continue
to guarantee that packets are delivered to layer 3 already properly
aligned (which are rules that are already in use).

Sync the thorpej-mips-cache branch with -current.

Add in support for timing out IPv4 routes added due to redirects,
as discussed in tech-net several weeks ago.  It turned out that
KAME had already added this functionality to the IPv6 stack, so
I followed their example in adding the sysctl variables
net.inet.icmp.rediraccept and net.inet.icmp.redirtimeout.

Update thorpej_scsipi to -current as of a month ago

count successful path MTU changes.  good for debugging.
(there could be some discussion on when to increase the counter...)

pullup (approved by releng-1-5)

switch from net.inet*.*.*ratelimit to net.inet*.*.ppslimit.

(tags are rough estimate - we had some try-and-error in main trunc)
sys/netinet/icmp6.h             1.9 -> 1.11
sys/netinet/icmp_var.h          1.15 -> 1.17
sys/netinet/in_proto.c          1.39 -> 1.42
sys/netinet/ip_icmp.c           1.50 -> 1.51, 1.52 -> 1.54
sys/netinet/tcp_input.c         1.111 -> 1.112, 1.115 -> 1.117
sys/netinet/tcp_usrreq.c        1.52 -> 1.53
sys/netinet/tcp_var.h           1.72 -> 1.75
sys/netinet6/icmp6.c            1.34 -> 1.35, 1.36 -> 1.38
sys/netinet6/in6_proto.c        1.17 -> 1.19

nuke the following sysctl variables.  "ppsratelimit" should work better.
need to recompile sbin/sysctl after updating /usr/include.
	net.inet.tcp.rstratelimit
	net.inet.icmp.errratelimit
	net.inet6.icmp6.errratelimit

implement net.inet.icmp.errppslimit.
make default value for net.inet.icmp.erratelimit to 0, as < 10ms value
does not do the right thing.

Sync w/ netbsd-1-5-base.

add icmpreturndatabytes kernel variable (default 8) which specifies the
number of extra data bytes to return in ICMP error messages.  This is
also available via sysctl as net.icmp.returndatabytes and is limited to
[8,512].

Add ICMP error rate limiting, based on the same for ICMP6.

Note, we're reusing the previously unused slot for "MTU discovery" (which
was moved to the "net.inet.ip" branch of the sysctl tree quite some time
ago).

Pull up to last week's -current.

Update protocoles and interfaces stats counters to 64bit.
RTM_IFINFO is now 0xf, 0xe is RTM_OIFINFO which returns the old (if_msghdr14)
struct with 32bit counters (binary compat, conditioned on COMPAT_14).
Same for sysctl: node 3 is renamed NET_RT_OIFLIST, NET_RT_IFLIST is now node 4.
Change rt_msg1() to add an mbuf to the mbuf chain instead of just panic()
when the message is larger than MHLEN.

add/cleanup multiple inclusion protection.

Import sys/netinet from 4.4BSD-Lite for reference purposes.

remove extraneous icmp_do_mtudisc

change sysctl net.inet.icmp.mtudisc to net.inet.ip.mtudisc

Path MTU Discovery support.  This is turned off by default.
Use sysctl -w net.inet.icmp.mtudisc=1 to turn on.
Still to come:  path removal after some period, black hole detection

KERNEL -> _KERNEL

New RCS ID's, take two.  they're more aesthecially pleasant, and use 'NetBSD'

Update to 4.4-Lite networking code, with a few local changes.

Change the counters to be all the same type -- u_long.

Fix some inconsistent spacing; spaces at the end of lines, etc.

more rcsid additions and file header cleanups

Add consistent multiple-inclusion protection.
