[libvirt] [PATCH] Fix build --without-network
by Martin Kletzander 13 May '15

13 May '15

In order not to bring in any link dependencies, bridge driver doesn't use the usual stubs as other conditionally-built code does. However, having the function as a macro imposes a problem with possibly unused variables if just defined as "0". This was worked around by using (dom=dom, iface=iface, 0) which should act like a 0 if used in a condition. However, gcc still bugs about that, so I came up with another way how to fix that. Using static inline functions in the header won't collide with anything, it fixes the bug and does one thing that the macro didn't do. It checks whenther passed variables are pointers of compatible type. It has only one downside, and that is that we need to either a) define it with ATTRIBUTE_UNUSED, which needs an exception in cfg.mk or b) do something like ignore_value(variable); in the function body. I went with the first variant.

[libvirt] [PATCH] parallels: remove connection wide wait timeout
by Nikolay Shirokovskiy 13 May '15

13 May '15

We have a lot of passing arguments code just to pass connection object cause it holds jobTimeout. Taking into account that right now this value is defined at compile time let's just get rid of it and make arguments list more clear in many places. In case we later need some runtime configurable timeout value we can provide this value through arguments function already operate such as a parallels domain object etc as this timeouts are operation( and thus object) specific in practice.

[libvirt] time: event poll may become un-triggerable after changing system clock.
by zhang bo 13 May '15

13 May '15

event poll may become un-triggerable after changing system clock. The steps to reproduce the problem: 1 run event-test 1 define and start a domain with name vm1. 2 destroy vm1 3 change system time to 1 hour before when timer.expiresAt has been set in virEventPollUpdateTimeout (and before virEventPollDispatchTimeouts()). 4 event-test will recive no message until 1 hour later. The reasons for the problem is : 1 The value of timer.expiresAt is set by virTimeMillisNowRaw. virTimeMillisNowRaw is effectable by settimeofday(), bacause it uses CLOCK_REALTIME to get time. 2 If we change the system time to a time long before now, after that timer.expiresAt has been set. timer.expiresAt is not affected, while virEventPollDispatchTimeouts is. Suppose it's now May 12th, and we set it to 10th, then the expiresAt is 12th, and the time virEventPollDispatchTimeouts got is 10th. if (eventLoop.timeouts[i].expiresAt <= (now+20)) { // expiresAt will not be less than now until 2 days later. *Solution(not good enough)*: 1 change the clock mode in virTimeMillisNowRaw from REALTIME to MONOTONIC, which would not be affected by settimeofday(). 2 add the time got from clock_gettime(*MONOTONIC*) with the system-start-time from epoch, making it equal to the value got from REALTIME. 3 As that the timestamp of the log message should follow system time, so we keep it to REALTIME as before. However, there's still problems: 1 pthread_cond_wait() gets time with REALTIME mode. When we change system time, pthread_cond_wait() may still be affected. So, Is there any other better solution? thanks in advance. oscar

It is unhealthy. If the device is not doing any DMA operations it would work - but if you are saving and there are DMA operations happening the chance of corruption (outstanding DMAs) increase. As such re-use the check migration used.

[libvirt] [PATCHv2] conf: fix no error when set an unsupport string in ./devices/shmem/msi[@ioeventfd]
by Luyao Huang 13 May '15

13 May '15

https://bugzilla.redhat.com/show_bug.cgi?id=1220265 Pass the return value to an enum directly is not safe. When pass a invalid @ioeventfd and virTristateSwitchTypeFromString return -1 to def->msi.ioeventfd, and this value transform to 4294967295, so no error when the parse failed. To fix this issue, folter the value using int and then assign it to virTristateSwitch as it's done.
