It implements a network I/O backend for KDB/KGDB, the kernel debugger. I sent this patch set to linux-kernel, and was kindly referred to this list by David Miller as the right place for feedback. 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. [PATCH 1/2] NETPOLL: Extend rx_hook support. [PATCH 2/2] NETKGDB: Ethernet/UDP/IP KDB transport. Thanks, A
