Re: cross-gcc for itanium
Date: Sun, 18 Sep 2011 05:06:04 +0300 From: Paul Irofti p...@irofti.net This makes the cross-gcc target for ia64 build, okay? That is gcc3 stuff. You should use gcc4 for ia64.
bgpd initial graceful restart support
Please test this diff whereever possible and make sure it does not cause
troubles with certain peers for you.
This is the first bit of support of graceful restart.
The diff only implements the procedures for the receiving speaker (aka the
box that was not restarted). So bgpd will not preserve its rouing table
accross restarts (that's for later) but will do the handling when a GR
capable neighbor restarts.
Note: bgpd will not announce the graceful restart capability by default.
Use announce restart yes to turn it on.
I will probably commit this later this week so you have been warned :)

Re: hide kernel threads in ps?
Having muttered a bunch, I'm in favor of this.

The distinction betwen kernel threads and kernel visible threads is certainly obvious to everyone, but this also seems more consise to me. Having said that, I'm fine with the shortened paragraph.
