Lots of netfilter hacking over the last couple of days

Following-up meeting the other networking hackers at netconf, I got really extremely motivated and basically spent every single minute hacking code.

The projects include:

• skb shrinkage (already merged in DaveM's net-2.6.14 tree)
• nfnetlink (already merged in DaveM's net-2.6.14 tree)
• conntrack event notifiers (already merged in DaveM's net-2.6.14 tree)
• ctnetlink (reworked to use network byte order in all the payload)
• nfnetlink_queue (a nfnetlink-based queue implementation)
• vdev (a virtual device that allows you to use multiple mac addresses on one Ethernet device)
• mmio_test (include support for machine-parseable reporting)

OLS Day 1

I didn't actually visit any of the talks, but instead read some of the papers in the written proceedings, hacking lots of code and talking to various people.

I've also managed to convince GregKH that support for async URB submission from userspace needs CONFIG_BROKEN. libusb doesn't use it anyway, and the number of users of this interface is limited. Unfortunately one of my customers is one of the users, so I might be forced to implement a cleaner interface for the same purpose.
