* User tools send evtchn notifications via /dev/xen/evtchnkaf24@firebug.cl.cam.ac.uk2005-10-061-2/+9
| | | | | | | | rather than using hypercall directly. Signed-off-by: Keir Fraser <keir@xensource.com>
* Change how event channels are allocated and used by the controlkaf24@firebug.cl.cam.ac.uk2005-10-061-27/+28
| | | | | | | | | | | | | | tools. /dev/xen/evtchn is now used by daemons to connect to remote domains: the advantage is that the local ports are garbage collected automatically if the daemon dies. xen no longer constructs end-to-end event-channel port pairs -- it allocates an unbound port in new domU and writes that port to xenstore. It is then picked up by teh appropriate daemon which does interdomain bind via /dev/xen/evtchn. Signed-off-by: Keir Fraser <keir@xensource.com>
* Send event-channel notification from console daemonkaf24@firebug.cl.cam.ac.uk2005-10-051-0/+6
| | | | | | | | | | to guest console driver when the output ring is emptied. This can be used to kick transmission of more characters without needing to poll. Signed-off-by: Keir Fraser <keir@xensource.com>
* xenstore fires @releaseDomain both when a domain shutskaf24@firebug.cl.cam.ac.uk2005-09-261-1/+1
| | | | | | | | | | | down and when it eventually dies. xenconsoled now only relinquishes its handle on a domain when it dies. This allows us to 'xm console' connect to a crashed domain, which is very useful! Signed-off-by: Keir Fraser <keir@xensource.com>
* Remove iflag argument to xs_writecl349@firebug.cl.cam.ac.uk2005-09-191-1/+1
| | | | | | | | | | xs_write with O_CREAT|O_EXCL causes problems over daemon restarts, since it's not idempotent. It turns out noone really needs the flags word at all, so get rid of it. It's now as if everyone specified "O_CREAT". Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Christian Limpach <Christian.Limpach@cl.cam.ac.uk>

* Fix save/restore when using grant tables in network, robust-ify netback shand@ubuntu.eng.hq.xensource.com2005-09-011-1/+1
| | | | | | | | | | | against bogus front-end drivers, plus various small cleanups. Note that there is now only /one/ config option controlling the use of grant tables with networking (not separate ones for rx and tx). An outstanding issue is that console reconnect after a restore causes badness. Signed-off-by: Steven Hand <steven@xensource.com>
* Wait a little bit for tty to appear.cl349@firebug.cl.cam.ac.uk2005-08-311-1/+26
| | | | | | | | | There is a race condition that occurs after xend creates a domain. The console client might be running before the console daemon has noticed the new domain and setup a pty for it.

The attached patch fixes this. 1) Fix uninitialized next pointer. This could sometimes cause xenconsoled to SEGV on an invalid domain pointer 2) Fix race condition in iterating domain list where removing a domain in a callback could lead to the iterators becoming invalid.
