itojun 4f825aaddd recover traditional MINCLSIZE (= MHLEN + MLEN + 1). it will make 
drivers less aggressive about use of cluster mbufs.

this chnage affects drivers with m_devget()-emulation.  many of
recent drivers do not look at MINCLSIZE any more, not sure why.

itojun 73a29e35ff do not forward packet with :: in the source. 
this is not in the spec - we had rough consensus on it in ipngwg,
spec will get updated to include this behavior.

itojun 928dfa5233 do not disable icmp error rate limitation for local address. 
local address can be abused too.  pps rate limitation should work fine for
moderate amount of icmp errors.

itojun dd9f2f7f1d implement net.inet.tcp.rstppslimit to limit TCP RSTs by packet-per-second 
basis.  default: 100pps

set default value for net.inet.tcp.rstratelimit to 0 (disabled),
NOTE: it does not work right for smaller-than-1/hz interval.  maybe we should
nuke it, or make it impossible to set smaller-than-1/hz value.

jeffs 3eae1609f1 Fix to actually compile MIPS1 only. 2000-07-27 08:28:36 +00:00
jeffs e4a0934c13 Do not attempt mips3 style cache flush on mips1 in setregs() as it 
is illegal to flush on user addresses.  In theory the race exists
on MIPS1, but it is rather unlikely in common use.  I have
seen it with regress/sys/kern/sigtramp on a QED 5231 system.

itojun a18c2d780f be proactive about unspecified IPv6 source address. pcb layer uses 
unspecified address (::) to mean "unbounded" or "unconnected",
and can be confused by packets from outside.

use of :: as source is not documented well in IPv6 specification.

not sure if it presents a real threat.  the worst case scenario is a DoS
against TCP listening socket:
- outsider transmit TCP SYN with :: as IPv6 source
- receiving side creates TCP control block with:
	local address = my addres
	remote address = ::     (meaning "unconnected")
	state = SYN_RCVD
  note that SYN ACK will not be sent due to ip6_output() filter.
  this stays until it timeouts.
- the TCP control block prevents listening TCP control block from
  being contacted (DoS).

udp6/raw6 socket may have similar problem, but as they are connectionless,
it may too much to filter it out.

cgd 4adc7b9704 add nops after jals in PANIC and PRINTF. (these macros are often used in 
code which has noreorder set, and they're not used with nops afterwards,
as is appropriate in that case, so put the nops in the macros.)

pk 2079f86890 On-board devices on psycho machines seem to have the `interrupt' property 
in the parent bus format (i.e. an INO) rather than being represented as
an PCI interrupt line. Provide a hack to work around this in pci_attach_hook().

mycroft 93a8d5ffea The ELF ABI declares that argc must fill an `argument slot'. Make it so. 
For __sparc_v9__ only, do a hack to make old executables continue to work --
for now.
