Earlier, I upgraded to cvs-HEAD to get the reintegration fix patch, and ended up with buggy rpc2 code and all my venii crashed :-(. I backed off from that and now all is ok.
In the middle of all this, I'm also debugging significant surgery to the PF_KEY code on my laptop. Bugs in my code caused IPsec to be unstable, and thus I didn't run racoon (IKE daemon), and venus couldn't talk to the coda server. I had been editing my software development log file, but was losing due to the emacs/NetBSD/SIGIO problem, so I stopped and kept a local copy. Then, I wanted to apply a patch to du I had developed for FreeBSD (to not report sizes of files marked 'nodump'). Without thinking, I grabbed the patch out of /coda/home/gdt/PATCHES/FREEBSD, edited it into the NetBSD source, and ran 'cvs diff' redirecting to /coda/home/gdt/PATCHES/NETBSD/du-nodump. I did this all forgetting that I had no connectivity to the server. Later, I got IPsec stable enough, rebooted, started up racoon and venus, and my changes got reintegrated correctly as soon as I got tokens. I know this _shouldn't_ be exciting, but it was, particularly given my recent adventures. On the subject of emacs, compiling emacs21 with #define BROKEN_SIGIO added to /usr/pkgsrc/editors/emacs21/work/emacs-21.2/src/s/netbsd.h seems to result in satisfactory operation. Thanks to Brett for the hint. So, it seems that the coda kernel code in NetBSD 1.6 doesn't handle signals well.
