Currently the fdstream function hardcodes the location of the iohelper to LIBEXECDIR "/libvirt_iohelper". This is not convenient when trying to write test cases which use this code. Add a virFDStreamSetIOHelper method to allow the test cases to point to the location of the un-installed iohelper binary. Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

In b2878ed8 we added the O_NOCTTY flag when opening files in the stream code. Unfortunately a later piece of code was comparing the flags == O_RDONLY, without masking out the non-access mode flags. This broke the iohelper when used with streams for read, since it caused us to attach the stream output pipe to the stream input FD instead of output FD :-( Signed-off-by: NDaniel P.

The source code base needs to be adapted as well. Some files include virutil.h just for the string related functions (here, the include is substituted to match the new file), some include virutil.h without any need (here, the include is removed), and some require both.

Ensure that the driver struct field names match the public API names. For an API virXXXX we must have a driver struct field xXXXX. ie strip the leading 'vir' and lowercase any leading uppercase letters. Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

When opening a stream to a device which is a TTY, that device may become the controlling TTY of libvirtd, if libvirtd was daemonized. This in turn means when the other end of the stream closes, libvirtd gets SIGHUP, causing it to reload its config. Prevent this by forcing O_NOCTTY on all streams that are opened Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

Wen Congyang reported that we have a double-close bug if we fail virFDStreamOpenInternal, since childfd duplicated one of the fds[] array contents. In truth, since we always transfer both members of fds to other variables, we should close the fds through those other names, and just use fds[] for pipe(). Bug present since 0.9.0 (commit e886237a). * src/fdstream.c (virFDStreamOpenFileInternal): Swap scope of childfd and fds[], to avoid a double close.

virCommandRunAsync() will set errfd if it succeed. We should close it if virFDStreamOpenInternal() fails.

This patch adds another callback to a FDstream object. The original callback is used by the daemon stream driver to handle events. This callback is called if and only if the stream is about to be closed. This might be used to handle cleanup steps after a fdstream exits. This will be used later on in ensuring mutually exclusive access to consoles. * src/fdstream.c: - emit the callback, when stream is being closed - add data structures needed to handle the callback - add function to register callback * src/fdstream.h: - define function prototypes for the callback

This patch causes the fdstream driver to call the stream event callback if virStreamAbort() is called on a stream using this driver. A remote handler for a stream can only detect changes via stream events, so this event callback is necessary in order to enable a daemon to abort a stream in such a way that the client will see the change. * src/fdstream.c: - modify close function to call stream event callback

In virFDStreamOpenFileInternal(), a errfd pipe is opened by virCommandRunAsync() and given to virFDStreamOpenInternal(). It seems virFDStream should close errfd, just like the other fd it is given. This fixes screenshots leaking FDs: http://bugzilla.redhat.com/show_bug.cgi?id=745761

Revert 6a1f5f56. Now that libvirt_iohelper takes fds by inheritance rather than by open() (commit 1eb66479), there is no longer a race where the parent can unlink() a file prior to the iohelper open()ing the same file. From there, it makes more sense to have the callers both create and unlink, rather than the caller create and the stream unlink, since the latter was only needed when iohelper had to do the unlink. * src/fdstream.h (virFDStreamOpenFile, virFDStreamCreateFile): Callers are responsible for deletion. * src/fdstream.c (virFDStreamOpenFileInternal): Don't leak created file on failure.

Rather than making the iohelper subject to a race in reopening the file, it is nicer to pass an already-open fd by inheritance. The old synopsis form must continue to work - if someone updates their libvirt package and installs a new libvirt_iohelper but without restarting the old libvirtd daemon, then the daemon can still make calls using the old syntax but the new iohelper. * src/util/iohelper.c (runIO): Split code for open...

Enforce the recent flags cleanups - we want to use 'unsigned int flags' in any of our APIs (except where backwards compatibility is important, in the public migration APIs), and that all flags are checked for validity (except when there are stub functions that completely ignore the flags argument).

Continuation of commit 313ac7fd, and enforce things with a syntax check. Technically, virNetServerClientCalculateHandleMode is not printing a mode_t, but rather a collection of VIR_EVENT_HANDLE_* bits; however, these bits are < 8, so there is no different in the output, and that was the easiest way to silence the new syntax check. * cfg.mk (sc_flags_debug): New syntax check.
