- Big OpenBSD CVS update (mainly beginnings of SSH2 infrastructure)
- [auth.c session.c sshd.c auth.h] split sshd.c -> auth.c session.c sshd.c plus cleanup and goto-removal - [bufaux.c bufaux.h] support ssh2 bignums - [channels.c channels.h clientloop.c sshd.c nchan.c nchan.h packet.c] [readconf.c ssh.c ssh.h serverloop.c] replace big switch() with function tables (prepare for ssh2) - [ssh2.h] ssh2 message type codes - [sshd.8] reorder Xr to avoid cutting - [serverloop.c] close(fdin) if fdin != fdout, shutdown otherwise, ok theo@ - [channels.c] missing close allow bigger packets - [cipher.c cipher.h] support ssh2 ciphers - [compress.c] cleanup, less code - [dispatch.c dispatch.h] function tables for different message types - [log-server.c] do not log() if debuggin to stderr rename a cpp symbol, to avoid param.h collision - [mpaux.c] KNF - [nchan.c] sync w/ channels.c
