f8fc96b551 Fixed vnode corruption by undefined case in union_lookup(). When 
uerror == 0 && lerror == EACCES, lowervp == NULLVP and union_allocvp
doesn't find existing union node and new union node is created.

Sicne it is dificult to cover all the case, union_lookup always
returns when union_lookup1() returns EACCES.

2c060c765a Fix a traceroute problem in the CISCO HDLC mode. (cisco routers not 
returning ICMP_TIMXCEED)

use CISCO_UNICAST instead of CISCO_MULTICAST to send normal packets.
this is needed for packets to get processed by a cisco router,
but doesn't matter if a packet is just forwarded.

49356a1f4a Fix procfs security hole -- check permissions on meaningful I/Os (namely, 
reading/writing of mem and regs).  Also have to check for the requesting
process being group KMEM -- this is a bit of a hack, but ps et al need it.

16e2a68bff Implement the LCP fail_counter: if an option has been NAK'ed for more 
than max_failures attempts, we are going to REJ it, to prevent endless
NAK loops.

(This is actually part of a larger local set of modifications i'm
running with, but the remainder (PAP & CHAP) ain't ready for prime-
time yet.)

c0ecffb96b Modify the scheduling policy to take into account disk I/O waits 
as chargeable CPU usage.  This should mitigate the problem of processes
doing disk I/O hogging the CPU.  Various users have reported the
problem, and test code shows that the problem should now be gone.

Add support for MODEX 320x240x256color with "unchained" adressing, giving

Also make sysmouse use the right resolution in graphics modes.

750f6aad7b Support interface names up to 15 characters in length. In order to 
accommodate the expanded name, the ICMP types bitmap has been
reduced from 256 bits to 32.

A recompile of kernel and user level ipfw is required.

To be merged into 2.2 after a brief period in -current.
