2012-02-01Add basic version of bridge helperCorey Bryant
This patch adds a helper that can be used to create a tap device attached to a bridge device. Since this helper is minimal in what it does, it can be given CAP_NET_ADMIN which allows qemu to avoid running as root while still satisfying the majority of what users tend to want to do with tap devices. The way this all works is that qemu launches this helper passing a bridge name and the name of an inherited file descriptor. The descriptor is one end of a socketpair() of domain sockets. This domain socket is used to transmit a file descriptor of the opened tap device from the helper to qemu. The helper can then exit and let qemu use the tap device.

2012-01-27qom: add the base Object class (v2)Anthony Liguori
This class provides the main building block for QEMU Object Model and is extensively documented in the header file. It is largely inspired by GObject. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> --- v1 -> v2 - remove printf() in type registration - fix typo in comment (Paolo) - make Interface private - move object into a new directory and move header into include/qemu/ - don't make object.h depend on qemu-common.h - remove Type and replace it with TypeImpl * (Paolo) - use hash table to store types (Paolo) - aggressively cache parent type (Paolo) - make a type_register and use it with interfaces (Paolo) - fix interface cast comment (Paolo) - add a few more functions required in later series
2012-01-19Makefile: Remove generated headers on cleanAndreas Färber
Running `make distclean' followed by a new out-of-tree build would fail due to stale generated QMP headers in the tree. Commit 611b727374ad76fb0078ea65bc1387194913980e (Makefile: remove more generated files on clean) made sure generated sources are removed. Also remove generated headers introduced in commit e3193601c84558c303b1773379da76fce80c0a56 (qapi: use middle mode in QMP server).

2012-01-19Makefile: Exclude tests/Makefile in unconfigured treeAndreas Färber
Since commit dbfe06c62ccedc5b64e1c6466445133dd50f6de1 (build: split unit test builds to a separate makefile fragment), in absence of config-host.mak an undefined $(SRC_PATH) breaks `make distclean' due to /tests/Makefile not being include'able.

2012-01-12Fix qapi code generation fixAvi Kivity
The fixes to qapi code generation had multiple bugs: - the Null class used to drop output was missing some methods - in some scripts it was never instantiated, leading to a None return, which is missing even more methods - the --source and --header options were swapped Luckily, all those bugs were hidden by a makefile bug which caused the old behaviour (with the race) to be invoked.

2011-12-27Fix qapi code generation wrt parallel buildAvi Kivity
Make's multiple output syntax x.c x.h: x.template gen < x.template actually invokes the command once for x.c and once for x.h (with differing $@ in each invocation). During a parallel build, the two commands may be invoked in parallel; this opens up a race, where the second invocation trashes a file supposedly produced during the first, and now in use by a dependent command. The various qapi code generators are susceptible to this; fix by making them generate just one file per invocation.

We have a single rule generating .c and .h files, so .h doesn't depend on .c: both depend on the source schema.

2011-09-23Makefile: Remove 'tarbin' targetPeter Maydell
Remove the 'tarbin' target -- it isn't used as part of the official QEMU release process, and it's out of date (various new bios files were never added to its list of files). It's better not to provide it at all than to have a broken makefile target we never use or test. (Creating a tarball by just pulling in binaries that have been installed directly to the system you're running the build on is a bad idea anyway: the better way to create a binary tarball would be just to install to a temporary DESTDIR and then tar up that.)

This patch tries to cull any uneeded library dependencies from the guest agent to improve portability across various distros. We do so by being as explicit as possible about in-tree dependencies rather than relying on existing *-obj-y targets, and by manually setting LIBS for the qemu-ga target to avoid pulling in LIBS_TOOLS libraries discovered by configure.
