* maint: Include bug-reporting info in --help outputEric Blake2017-08-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | These days, many programs are including a bug-reporting address, or better yet, a link to the project web site, at the tail of their --help output. However, we were not very consistent at doing so: only qemu-nbd and qemu-qa mentioned anything, with the latter pointing to an individual person instead of the project. Add a new #define that sets up a uniform string, mentioning both bug reporting instructions and overall project details, and which a downstream vendor could tweak if they want bugs to go to a downstream database. Then use it in all of our binaries which have --help output. The canned text intentionally references http:// instead of https:// because our https website currently causes certificate errors in some browsers. That can be tweaked later once we have resolved the web site issued. Signed-off-by: Eric Blake <eblake@redhat.com> Reviewed-by: Daniel P.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases the slave devices of a virtual block device are tracked by the parent in the corresponding sysfs node. For instance, if we have a loop-back mount of the form: /dev/loop3p1 on /home/mdroth/mnt type ext4 (rw,relatime,data=ordered) this will be reflected in sysfs as: /sys/devices/virtual/block/loop3/ ... /sys/devices/virtual/block/loop3/slaves /sys/devices/virtual/block/loop3/loop3p1 The current code however assumes the mounted virtual block device, loop3p1 in this case, contains the slaves directory, and reports an error otherwise. This breaks 'make check' in certain environments. Fix this by simply skipping attempts to generate disk topology information in these cases. Since this information is documented in QAPI as optionally-reported, this should be ok from an API perspective. In the future, this can possibly be improved upon by collecting topology information from the parent in these cases.

* qemu-ga: obey LISTEN_PID when using systemd socket activationPaolo Bonzini2017-03-191-38/+13Star
| | | | | | | | | | | | | | | | | | | | | qemu-ga's socket activation support was not obeying the LISTEN_PID environment variable, which avoids that a process uses a socket-activation file descriptor meant for its parent. Mess can for example ensue if a process forks a children before consuming the socket-activation file descriptor and therefore setting O_CLOEXEC on it. Luckily, qemu-nbd also got socket activation code, and its copy does support LISTEN_PID. Some extra fixups are needed to ensure that the code can be used for both, but that's what this patch does. The main change is to replace get_listen_fds's "consume" argument with the FIRST_SOCKET_ACTIVATION_FD macro from the qemu-nbd code. Cc: "Richard W.M.

* qapi: The #optional tag is redundant, dropMarkus Armbruster2017-03-161-19/+19
| | | | | | | | | | | | | | | | | | | | | | | | | We traditionally mark optional members #optional in the doc comment. Before commit 3313b61, this was entirely manual. Commit 3313b61 added some automation because its qapi2texi.py relied on #optional to determine whether a member is optional. This is no longer the case since the previous commit: the only thing qapi2texi.py still does with #optional is stripping it out. We still reject bogus qapi-schema.json and six places for qga/qapi-schema.json. Thus, you can't actually rely on #optional to see whether something is optional. Yet we still make people add it manually. That's just busy-work. Drop the code to check, fix up and strip out #optional, along with all instances of #optional. To keep it out, add code to reject it, to be dropped again once the dust settles. No change to generated documentation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Since we added the documentation generator in commit 3313b61, doc comments are mandatory. That's a very good idea for a schema that needs to be documented, but has proven to be annoying for testing. Make doc comments optional again, but add a new directive { 'pragma': { 'doc-required': true } } to let a QAPI schema require them. Add test cases for the new pragma directive. While there, plug a minor hole in includ directive test coverage. Require documentation in the schemas we actually want documented: qapi-schema.json and qga/qapi-schema.json.

This allows systemd to manage the listen socket until the first client connects and between restarts. Advantages of socket activation are that parallel startup of network services becomes possible and that unused daemons do not consume memory. The key to achieving this is the LISTEN_FDS environment variable, which is a stable ABI as shown here: https://www.freedesktop.org/wiki/Software/systemd/InterfacePortabilityAndStabilityChart/ We could link against libsystemd and use sd_listen_fds(3) but it's easy to implement the tiny LISTEN_FDS ABI so that qemu-ga does not depend on libsystemd. Some systems may not have systemd installed and wish to avoid the dependency. Other init systems or socket activation servers may implement the same ABI without systemd involvement.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The way we get QMP commands registered is high tech: * qapi-commands.py generates qmp_init_marshal() that does the actual work * it also generates the magic to register it as a MODULE_INIT_QAPI function, so it runs when someone calls module_call_init(MODULE_INIT_QAPI) * main() calls module_call_init() QEMU needs to register a few non-qapified commands. Same high tech works: monitor.c has its own qmp_init_marshal() along with the magic to make it run in module_call_init(MODULE_INIT_QAPI). QEMU also needs to unregister commands that are not wanted in this build's configuration (commit 5032a16). Simple enough: qmp_unregister_commands_hack(). The difficulty is to make it run after the generated qmp_init_marshal(). We can't simply run it in monitor.c's qmp_init_marshal(), because the order in which the registered functions run is indeterminate. So qmp_init_marshal() registers qmp_unregister_commands_hack() separately. Since registering *appends* to the list of registered functions, this will make it run after all the functions that have been registered already. I suspect it takes a long and expensive computer science education to not find this silly. Dumb it down as follows: * Drop MODULE_INIT_QAPI entirely * Give the generated qmp_init_marshal() external linkage. * Call it instead of module_call_init(MODULE_INIT_QAPI) * Except in QEMU proper, call new monitor_init_qmp_commands() that in turn calls the generated qmp_init_marshal(), registers the additional commands and unregisters the unwanted ones.

| | | | | | | | | | | | | | | | | | Throughout the code there are c->listen_channel checks which manage the listen socket file descriptor (waiting for accept(2), closing the file descriptor, etc). These checks are currently preceded by explicit c->method == GA_CHANNEL_UNIX_LISTEN checks. Explicit GA_CHANNEL_UNIX_LISTEN checks are not necessary since serial channel types do not create the listen channel (c->listen_channel). As more listen channel types are added, explicitly checking all of them becomes messy. Rely on c->listen_channel to determine whether or not a listen socket file descriptor is used.

As QEMU has its own primitives with well understood semantics we might as well use them. The use of atomics was a little inconsistent so I've also ensure the values are correctly set with atomic primitives at the same time. I also made the usage of bool consistent while I was at it.

* | rules.mak: quiet-command: Split command name and args to printPeter Maydell2016-10-061-3/+3
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The quiet-command make rule currently takes two arguments: the command and arguments to run, and a string to print if the V flag is not set (ie we are not being verbose). By convention, the string printed is of the form " NAME some args". Unfortunately to get nicely lined up output all the strings have to agree about what column the arguments should start in, which means that if we add a new quiet-command usage which wants a slightly longer CMD name then we either put up with misalignment or change every quiet-command string. Split the quiet-mode string into two, the "NAME" and the "same args" part, and use printf(1) to format the string automatically. This means we only need to change one place if we want to support a longer maximum name. In particular, we can now print 7-character names lined up properly (they are needed for the OSX "SETTOOL" invocation). Change all the uses of quiet-command to the new syntax. (Any which are missed or inadvertently reintroduced via later merges will result in slightly misformatted quiet output rather than disaster.) A few places in the pc-bios/ makefiles are updated to use "BUILD", "SIGN" and "STRIP" rather than "Building", "Signing" and "Stripping" for consistency and to keep them below 7 characters. Module .mo links now print "LD" rather than the nonstandard "LD -r".
