[libvirt] [PATCH v6 0/5] Add TXT record and hosts support for DNS service and dnsmasq command-line regression testing
by Michal Novotny 24 Jun '11

24 Jun '11

Hi, this is the 6th (and hopefully the last) version of my patch to introduce the TXT record and DNS hosts support for the DNS service on the virtual network. This can be defined using the txt subelement in the dns element of the network XML description. The definition of TXT record names containing spaces is rejected with the error message that TXT record names in DNS doesn't support spaces. Also, regression testing for the dnsmasq command line has been added to test whether the dnsmasq command-line is correct or not. The new XML definition syntax is: <dns> <txt name="example" value="example value" /> <host ip='192.168.122.1'> <hostname>gateway</hostname> <hostname>host</hostname> </host> </dns> Where multiple host elements can be defined to put the aliases. The <dns> element have to be present on the <ip> level, i.e. one level upper than it was in version 2 of the patch since the definition affects all the IP addresses on the network. The patch series has been tested for the configuration and it was working fine and also RelaxNG schema with the tests have been both altered to add test cases to test those patches. This is the new version for latest libvirt codebase so please review the patchset. Some fixes and code optimizations were done by Laine Stump, so I'm adding him into the SOB clause as well ;-) Please review.

[libvirt] [PATCH] Move load of AppArmor profile to GenLabel()
by Jamie Strandboge 24 Jun '11

24 Jun '11

Commit 12317957ecd6c37a2fb16275dcdeeacfe25c517 introduced an incompatible architectural change for the AppArmor security driver. Specifically, virSecurityManagerSetAllLabel() is now called much later in src/qemu/qemu_process.c:qemuProcessStart(). Previously, SetAllLabel() was called immediately after GenLabel() such that after the dynamic label (profile name) was generated, SetAllLabel() would be called to create and load the AppArmor profile into the kernel before qemuProcessHook() was executed. With 12317957ecd6c37a2fb16275dcdeeacfe25c517, qemuProcessHook() is now called before SetAllLabel(), such that aa_change_profile() ends up being called before the AppArmor profile is loaded into the kernel (via ProcessLabel() in qemuProcessHook()). This patch addresses the change by making GenLabel() load the AppArmor profile into the kernel after the label (profile name) is generated. SetAllLabel() is then adjusted to only reload_profile() and append stdin_fn to the profile when it is specified. This also makes the AppArmor driver work like its SELinux counterpart with regard to SetAllLabel() and stdin_fn. Passes its part of 'check' and 'syntax-check' (though libvirt_net_rpc_la-virnetmessage.lo failed to compile and po_check failed the syntax check for unrelated reasons). Prior to writing this patch, the issue was discussed on IRC with Daniel Berrange and Eric Blake. Other discussed alternatives were to do a 2 stage qemuProcessHook(), where ProcessLabel() was only called in the second stage after the handshake. In attempting this, it still didn't address the fact that aa_change_profile() was being called on an unloaded profile so it was abandoned. Another idea was to create a second private API call that the AppArmor driver would use to load the profile that would be a no-op for the SElinux driver. I started to go this route, but in the end it was both unneeded and too complicated once I realized I could simply load the profile in GenLabel() and still use SetAllLabel() to reload the profile when stdin_path was specified. The current fix is implemented wholly within the AppArmor driver and I think much cleaner. Reference: https://launchpad.net/bugs/795800 -- Jamie Strandboge | http://www.canonical.com

[libvirt] Block pull API QEMU progress update
by Stefan Hajnoczi 24 Jun '11

24 Jun '11

I am sending this email as an update on the new image streaming for QEMU (aka block pull in libvirt). Adam's libvirt virDomainBlockPull patches were recently merged to allow populating a disk image while the domain is running. The QEMU side implementation is not merged into qemu.git yet because similarity with the live block copy feature has sparked discussion on how to unify the two. The QEMU APIs for image streaming and live block copy may or may not be changed. I think they should stay as they are because they provide good interfaces for those two features. However, it is possible that unifying the implementations of the two features internally necessitates changes to the QEMU APIs. If changes are made, the question becomes whether they require changing the libvirt block pull (and proposed live block copy) API. Right now there is no proposal to change the QEMU APIs for the two features but I think it is useful for libvirt to be aware of the status on these features. Perhaps a precautionary measure like not committing to the APIs until the QEMU patches are merged is worthwhile, just for safety. Marcelo, Kevin, and I are working on unifying the QEMU side implementations of live block copy and image streaming. Hopefully the specifics will be agreed soon and we can then enable these features in QEMU and libvirt. Stefan
