[libvirt] [PATCH] vbox: use user cache dir when screenshotting.
by Dawid Zamirski 12 Mar '15

12 Mar '15

For VBOX it's most likely that the connection is vbox:///session and it runs with local non-root account. This caused permission denied when LOCALSTATEDIR was used to create temp file. This patch makes use of the virGetUserCacheDirectory to address this problem for non-root users. --- src/vbox/vbox_common.c | 15 ++++++++++++++- 1 file changed, 14 insertions(+), 1 deletion(-) diff --git a/src/vbox/vbox_common.c b/src/vbox/vbox_common.c index 55d3624..a548252 100644 --- a/src/vbox/vbox_common.c +++ b/src/vbox/vbox_common.c @@ -7254,8 +7254,10 @@ vboxDomainScreenshot(virDomainPtr dom, IMachine *machine = NULL; nsresult rc; char *tmp; + char *cacheDir; int tmp_fd = -1; unsigned int max_screen; + uid_t uid = geteuid(); char *ret = NULL; if (!data->vboxObj) @@ -7288,8 +7290,18 @@ vboxDomainScreenshot(virDomainPtr dom, return NULL; } - if (virAsprintf(&tmp, "%s/cache/libvirt/vbox.screendump.XXXXXX", LOCALSTATEDIR) < 0) { + if (uid != 0) + cacheDir = virGetUserCacheDirectory(); + else { + if (virAsprintf(&cacheDir, "%s/cache/libvirt", LOCALSTATEDIR) < 0) { + VBOX_RELEASE(machine); + return NULL; + } + } + + if (cacheDir && virAsprintf(&tmp, "%s/vbox.screendump.XXXXXX", cacheDir) < 0) { VBOX_RELEASE(machine); + VIR_FREE(cacheDir); return NULL; } @@ -7368,6 +7380,7 @@ vboxDomainScreenshot(virDomainPtr dom, VIR_FORCE_CLOSE(tmp_fd); unlink(tmp); VIR_FREE(tmp); + VIR_FREE(cacheDir); VBOX_RELEASE(machine); vboxIIDUnalloc(&iid); return ret; -- 2.1.0

[libvirt] [PATCH v2] virnetdev: fix build with old kernel
by Pavel Hrdina 12 Mar '15

12 Mar '15

Commit c9027d8f added a detection of NIC HW features, but some of them are not available in old kernel. Very old kernels lack enum ethtool_flags and even if this enum is present, not all values are available for all kernels. To be sure that we have everything in kernel that we need, we must check for existence of most of that flags, because only few of them were defined at first. Also to successfully build libvirt with older kernel we need to include <linux/types.h> before <linux/ethtool.h> to have __u32 and friends defined.

[libvirt] [PATCH v3 00/15] Drop network driver lock
by Michal Privoznik 12 Mar '15

12 Mar '15

Well, this is interesting. I've turned the virNetworkObjList into using a virHash. And even though the performance in my testing (using the very same test program as in previous versions of the patch set) increased. Without these patches, the test program took 56s to finish. With these patches (that is with virHash table) it takes 46s, which is better. But previously, with network objects stored in flat array I was able to get somewhere around 23s! I wonder what may be the cause. NB, nearly all patches in the series have been ACKed already, but since I'm switching the virNetworkObjList internals, I'm posting them again. Michal Privoznik (15): virNetworkObjListPtr: Turn list into a hash table network_conf: Make virNetworkObj actually virObject network_conf: Introduce virNetworkObjEndAPI bridge_driver: Use virNetworkObjEndAPI test_driver: Use virNetworkObjEndAPI parallels_network: Use virNetworkObjEndAPI virNetworkObjList: Derive from virObjectLockableClass network_conf: Introduce locked versions of lookup functions virNetworkObjListPtr: Make APIs self-locking virNetworkObjFindBy*: Return an reference to found object struct _virNetworkDriverState: Annotate items bridge_driver: Drop networkDriverLock() from everywhere test_driver: Drop testDriverLock() from almost everywhere parallels_network: Drop parallelsDriverLock() from everywhere. bridge_driver: Use more of networkObjFromNetwork cfg.mk | 2 - src/conf/network_conf.c | 545 +++++++++++++++++++++++------------ src/conf/network_conf.h | 13 +- src/libvirt_private.syms | 7 +- src/network/bridge_driver.c | 197 +++---------- src/network/bridge_driver_platform.h | 5 +- src/parallels/parallels_network.c | 62 +--- src/test/test_driver.c | 108 ++----- tests/networkxml2conftest.c | 4 +- tests/objectlocking.ml | 4 - 10 files changed, 441 insertions(+), 506 deletions(-) -- 2.0.5

[libvirt] [PATCH 0/6] Coverity fixes
by John Ferlan 11 Mar '15

11 Mar '15

Some Coverity patches - the first one has been showing up in my dailies for a few days... The other 5 I don't see, but that's because I don't generally build with xenapi in my Coverity environment. So for those, I'm hoping someone with that environment could check them out.
