[libvirt] Plans for next release 2.4.0
by Daniel Veillard 24 Oct '16

24 Oct '16

I will be in vacation this week, but should be able to make the release candidate on Thursday, which means that if I can make a CR2 release on the week-end, we should be able to push 2.4.0 around Nov 1st if everything looks good. There is a few tests who went red in https://ci.centos.org/view/libvirt-project/ maybe something to look at in the meantime, thanks !

[libvirt] [PATCH 0/4] Complete virDomainChrSourceDefPtr adjustments
by John Ferlan 24 Oct '16

24 Oct '16

Similar to _virDomainChrDef, alter _virDomainSmartcardDef and _virDomainRedirdevDef in order to use a virDomainChrSourceDefPtr. This includes modifying the relevant allocations for the source. Next, modify the virDomainRNGDef allocation to use virDomainChrSourceNew rather than a straight VIR_ALLOC. Finally, add the "missing" iterators for RNG and Redirdev. All this should set up what's necessary in order to handle adding the TLS chardev TCP for all chr, smartcard, rng, and redirdev devices. John Ferlan (4): conf: Use virDomainChrSourceDefPtr for _virDomainSmartcardDef 'passthru' conf: Use virDomainChrSourceDefPtr for _virDomainRedirdevDef 'source.chr' conf: Use virDomainChrSourceDefNew for virDomainRNGDef allocation conf: Add iterators for RNG and Redirdev src/conf/domain_audit.c | 2 +- src/conf/domain_conf.c | 122 ++++++++++++++++++++++++++++++---------- src/conf/domain_conf.h | 22 +++++++- src/libvirt_private.syms | 2 + src/qemu/qemu_command.c | 4 +- src/qemu/qemu_hotplug.c | 2 +- src/security/security_selinux.c | 4 +- 7 files changed, 119 insertions(+), 39 deletions(-) -- 2.7.4

[libvirt] [PATCH 0/4] Add TLS for TCP chardev redirdev and rng backends
by John Ferlan 24 Oct '16

24 Oct '16

This "would" conflict with other TLS/TCP changes on list depending on order of commit, but it does work against the current top. The conflict would be limited to the new helper qemuDomainGetChardevTLSObjects and changing the 'if (!cfg->chardevTLS)' to the corresponding 'if dev->source.data.tcp.haveTLS != VIR_TRISTATE_BOOL_YES)' once Pavel's changes are in and of course removing the need to fetch 'cfg'. Then if my other changes related to making 'source' a pointer in the _virDomainChrDef is accepted, the 'source.' here would change to 'source->'. Essentially during the review process of adding a secret to access the TLS environment, it was determined that the backends for redirdev and rng weren't adding the TLS object on hotplug, even though the command line processing would add it. NB: Smartcard would be in the same category, but it doesn't support hotplug, so we're off the hook for that. John Ferlan (4): qemu: Introduce qemuDomainGetChardevTLSObjects for hotplug qemu: Clean up error path in qemuDomainAttachRedirdevDevice qemu: Add TLS hotplug for qemuDomainAttachRedirdevDevice qemu: Add TLS hotplug for qemuDomainAttachRNGDevice src/qemu/qemu_hotplug.c | 125 ++++++++++++++++++++++++++++++++++++++---------- 1 file changed, 99 insertions(+), 26 deletions(-) -- 2.7.4

If you have selinux/apparmour that will also block permission. This is an example of why usage of qemu:commandline is discouraged - it will always have problems with permissions if you pass files using it.

[libvirt] [PATCH 0/3] Alter 'source' to be virDomainChrSourceDefPtr in _virDomainChrDef
by John Ferlan 21 Oct '16

21 Oct '16

Yes, it's absolutely terrifying; however, in order to "fix" problems noted during the review of the TLS chardev TCP 'properly' making the 'source' be a pointer and then moving the 'privateData' from _virDomainChrDef to _virDomainChrSourceDef will allow for setting of the 'secinfo' for the smartcard, rng, and redirdev backends that use a TCP channel. 95% of the changes obviously fell out of build issues from a 'make check syntax-check'. The remaining 5% of the changes are from sources I don't normally build; however, those were found by using cscope on the sources and finding references of "source\.{type|data|logfile|logappend} (IOW: virDomainChrSourceDef members).

[libvirt] [PATCH 00/15] qemu: Add QMP schema introspection and use it to add gluster debug setting
by Peter Krempa 21 Oct '16

21 Oct '16

Add support for QMP schema introspection along with test data adding and fixup and use it to detect support for gluster debug setting in qemu. Thanks to Andrea and Pavel for gathering test data for me so I don't have to compile multiple qemu versions or deal with minority architectures. (I honoured them by granting them autorship on the patches) This series also includes the gluster posting from Prasanna which I've properly split, reordered and fixed.
