[libvirt] [GSoC] Introduction
by Sukrit Bhatnagar
Hi,
I am Sukrit Bhatnagar, selected in GSoC '18 for the project
"Automatic freeing of resources". I will be modifying the libvirt
core C library to add functionality for GCC cleanup attribute.
Over the next couple of months, I will be discussing the general
code design in this list. I had started a similar discussion a
few weeks ago [1].
I will also be continuing the addition of virQEMUBuildBufferEscapeComma
in qemu_command.c which I had been working on as a BiteSizedTask.
Looking forward to work with the libvirt community.

Thanks,

[libvirt] [jenkins-ci PATCH 0/5] guests: Enable ccache transparently
by Andrea Bolognani
This allows us to drop the ugly workaround from the Go and
MinGW templates; as a nice side-effect, we also remove the
need to hardcode most OS-dependent paths in the inventory.
Andrea Bolognani (5):
guests: Reorder tasks
guests: Figure out OS-dependent paths automatically
guests: Figure out more OS-dependent paths ahead of time
guests: Create ccache symlink farm
jobs: Remove $CC override

[libvirt] [PATCH] nwfilter: increase pcap buffer size to be compatible with TPACKET_V3
by Laine Stump
When an nwfilter rule sets the parameter CTRL_IP_LEARNING to "dhcp",
this turns on the "dhcpsnoop" thread, which uses libpcap to monitor
traffic on the domain's tap device and extract the IP address from the
DHCP response.
If libpcap on the host is built with TPACKET_V3 defined, the dhcpsnoop
code's initialization of the libpcap socket fails with the following
error:
virNWFilterSnoopDHCPOpen:1134 : internal error: pcap_setfilter: can't remove kernel filter: Bad file descriptor
It turns out that this was because libpcap with TPACKET_V3 defined
requires a larger buffer size than libvirt was setting (we were
setting it to 128k). Changing the buffer size to 256k eliminates the
error, and the dhcpsnoop thread once again works properly.
Thanks to Christian Ehrhardt <paelzer(a)gmail.com> for discovering that
buffer size was the problem.

[libvirt] [PATCH v2] logging: Don't inhibit shutdown in system daemon
by Martin Kletzander
That is a job of libvirtd and virtlogd has a dependency on it, so that will
prevent it properly. Doing it one extra time in virtlogd might also cause AVC
denials because it is not allowed to call that dbus method.
Caused by commit df34363d58bb.

I have an idea how to make this way nicer, but it requires a rework and maybe
people will not like it as much, so for now this is the preferred fix.

- Don't revert the shutdown inhibition for all instances, only for the system
one.

This basically reverts df34363d58bbf424d5c8170a93d3ad5dcd4afb26, but manually
due to the numerous changes since that was merged.
