Most code now uses the virProcess / virCommand APIs, so the need for sys/wait.h is quite limited. Removing this include removes the dependency on GNULIB providing a dummy sys/wait.h for Windows. Reviewed-by: NPavel Hrdina <phrdina@redhat.com> Signed-off-by: NDaniel P. Berrangé <berrange@redhat.com>

In many files there are header comments that contain an Author: statement, supposedly reflecting who originally wrote the code. In a large collaborative project like libvirt, any non-trivial file will have been modified by a large number of different contributors. IOW, the Author: comments are quickly out of date, omitting people who have made significant contribitions. In some places Author: lines have been added despite the person merely being responsible for creating the file by moving existing code out of another file. IOW, the Author: lines give an incorrect record of authorship. With this all in mind, the comments are useless as a means to identify who to talk to about code in a particular file. Contributors will always be better off using 'git log' and 'git blame' if they need to find the author of a particular bit of code. This commit thus deletes all Author: comments from the source and adds a rule to prevent them reappearing. The Copyright headers are similarly misleading and inaccurate, however, we cannot delete these as they have legal meaning, despite being largely inaccurate. In addition only the copyright holder is permitted to change their respective copyright statement. Reviewed-by: NErik Skultety <eskultet@redhat.com> Signed-off-by: NDaniel P.

Throughout the code, we have several places need to construct a path somewhere in /sys/class/net/... They are not consistent and nearly each code piece invents its own way how to do it. So unify this by: 1) use virNetDevSysfsFile() wherever possible 2) At least use common macro SYSFS_NET_DIR declared in virnetdev.h at the rest of places which can't go with 1) Signed-off-by: NMichal Privoznik <mprivozn@redhat.com>

This reverts commit 433b427f. The patch was added in order to overcome a bug in iproute2 and since it was properly identified as a bug, particularly in openSUSE 13.2, and it is being worked on [1], the best solution for libvirt seems to be to keep the old behaviour.

Due to a change (or bug?) in ip link implementation, the command 'ip link add vnet0...' is forced into 'ip link add name vnet0...' The changed command also works on older versions of iproute2, just the 'name' parameter has been made mandatory.

Auditing all callers of virCommandRun and virCommandWait that passed a non-NULL pointer for exit status turned up some interesting observations. Many callers were merely passing a pointer to avoid the overall command dying, but without caring what the exit status was - but these callers would be better off treating a child death by signal as an abnormal exit. Other callers were actually acting on the status, but not all of them remembered to filter by WIFEXITED and convert with WEXITSTATUS; depending on the platform, this can result in a status being reported as 256 times too big. And among those that correctly parse the output, it gets rather verbose. Finally, there were the callers that explicitly checked that the status was 0, and gave their own message, but with fewer details than what virCommand gives for free. So the best idea is to move the complexity out of callers and into virCommand - by default, we return the actual exit status already cleaned through WEXITSTATUS and treat signals as a failed command; but the few callers that care can ask for raw status and act on it themselves. * src/util/vircommand.h (virCommandRawStatus): New prototype. * src/libvirt_private.syms (util/command.h): Export it. * docs/internals/command.html.in: Document it. * src/util/vircommand.c (virCommandRawStatus): New function.

Consider dozen of LXC domains, each of them having this type of interface: <interface type='network'> <mac address='52:54:00:a7:05:4b'/> <source network='default'/> </interface> When starting these domain in parallel, all workers may meet in virNetDevVethCreate() where a race starts. Race over allocating veth pairs because allocation requires two steps: 1) find first nonexistent '/sys/class/net/vnet%d/' 2) run 'ip link add ...' command Now consider two threads. Both of them find N as the first unused veth index but only one of them succeeds allocating it. The other one fails. For such cases, we are running the allocation in a loop with 10 rounds. However this is very flaky synchronization. It should be rather used when libvirt is competing with other process than when libvirt threads fight each other. Therefore, internally we should use mutex to serialize callers, and do the allocation in loop (just in case we are competing with a different process). By the way we have something similar already since 1cf97c87. Signed-off-by: NMichal Privoznik <mprivozn@redhat.com>

The kernel automatically destroys veth devices when cleaning up the container network namespace. During normal shutdown, it is thus likely that the attempt to run 'ip link del vethN' will fail. If it fails, check if the device exists, and avoid reporting an error if it has gone. This switches to use the virCommand APIs instead of virRun too. Signed-off-by: NDaniel P.

These all existed before virfile.c was created, and for some reason weren't moved. This is mostly straightfoward, although the syntax rule prohibiting write() had to be changed to have an exception for virfile.c instead of virutil.c. This movement pointed out that there is a function called virBuildPath(), and another almost identical function called virFileBuildPath(). They really should be a single function, which I'll take care of as soon as I figure out what the arglist should look like.

Currently, the lxc implementation invokes 'ip' and 'ifconfig' commands inside a container using 'virRun'. That has the side effect of requiring those commands to be present and to function in a manner consistent with the usage. Some small roots (such as ttylinux) may not have 'ip' or 'ifconfig'. This patch replaces the use of these commands with usage of netdevice. The result is that lxc containers do not have to implement those commands, and lxc in libvirt is only dependent on the netdevice interface. I've tested this patch locally against the ubuntu libvirt version enough to verify its generally sane. I attempted to build upstream today, but failed with: /usr/bin/ld: ../src/.libs/libvirt_driver_qemu.a(libvirt_driver_qemu_la-qemu_domain.o): undefined reference to symbol 'xmlXPathRegisterNs@@LIBXML2_2.4.30 Thats probably a local issue only, but I wanted to get this patch up and see what others thought of it. This is ubuntu bug https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/828211 .
