Hi!
This is v2 of the tentative patch set I am sending for feedback. It implements a network I/O backend for KDB/KGDB, the kernel debugger.
NetKGDB is very similar to netconsole, on which it is based, but with a crucial difference - netkgdb is designed to accept connections from any hosts, i.e. it is not necessary to specify these ahead of time. This makes it that much more useful in a "this host crashed and a I want a developer to take a look at it" scenario, common to large scale test/QA farms and automated testing harnesses. This involves a minor change to the netpoll rx_hook, namely, to provide source connection information.
This differs from v1 in cleaning up the netdev notifier code, which was needlessly byzantine and had potential races, and in some docu- mentation changes.
I've also Cc'd Matt Mackall, who wrote the current netconsole code.
[PATCHv2 1/2] NETPOLL: Extend rx_hook support. [PATCHv2 2/2] NETKGDB: Ethernet/UDP/IP KDB transport.
