Have an interesting one here, originally found on xen 4.1.0 but just upgraded to xen 4.1.1 and it''s still here. Creating a VM with a tap2 device pointed at /dev/mapper/something, when that device doesn''t exist, causes the tapdisk2 process to go into D mode and also manages to take out any process that queries it. For example, I have /dev/mapper/nathanxenuk1 as a valid disk

...ssues. I can solve simple compiling and scripting problems, but that's about as far as it goes. Thanks though for helping my solve this issue. I appreciate it. Matt >>> darkeye@tyrell.hu 8/26/02 9:24:53 AM >>> OK, I now see that the send() on FreeBSD does not support the MSG_NOSIGNAL flag. As a short workaround you could simply change line 316 from: ret = send( sockfd, buf, len, MSG_NOSIGNAL); to ret = send( sockfd, buf, len, 0); <p>Later I'll try to add FreeBSD specific #ifdefs (are you familiar with these kinds of porting issues, e.g. how to make c...

While working on a new test of what happens when the server goes away while commands are in flight, I managed to hit a race where I hit death from SIGPIPE instead of a clean transition to the DEAD state. I also found myself wanting to use nbd_poll from the test, but with a way to distinguish between the state machine progressing vs. hanging. Eric Blake (2): socket: Avoid SIGPIPE where possible
