2016-07-18trace: Add per-vCPU tracing states for events with the 'vcpu' propertyLluís Vilanova

2016-07-13char: do not use atexit cleanup handlerMarc-André Lureau
It turns out qemu is calling exit() in various places from various threads without taking much care of resources state. The atexit() cleanup handlers cannot easily destroy resources that are in use (by the same thread or other). Since c1111a24a3, TCG arm guests run into the following abort() when running tests, the chardev mutex is locked during the write, so qemu_mutex_destroy() returns an error: #0 0x00007fffdbb806f5 in raise () at /lib64/libc.so.6 #1 0x00007fffdbb822fa in abort () at /lib64/libc.so.6 #2 0x00005555557616fe in error_exit (err=<optimized out>, msg=msg@entry=0x555555c38c30 <__func__.14622> "qemu_mutex_destroy") at /home/drjones/code/qemu/util/qemu-thread-posix.c:39 #3 0x0000555555b0be20 in qemu_mutex_destroy (mutex=mutex@entry=0x5555566aa0e0) at /home/drjones/code/qemu/util/qemu-thread-posix.c:57 #4 0x00005555558aab00 in qemu_chr_free_common (chr=0x5555566aa0e0) at /home/drjones/code/qemu/qemu-char.c:4029 #5 0x00005555558b05f9 in qemu_chr_delete (chr=<optimized out>) at /home/drjones/code/qemu/qemu-char.c:4038 #6 0x00005555558b05f9 in qemu_chr_delete (chr=<optimized out>) at /home/drjones/code/qemu/qemu-char.c:4044 #7 0x00005555558b062c in qemu_chr_cleanup () at /home/drjones/code/qemu/qemu-char.c:4557 #8 0x00007fffdbb851e8 in __run_exit_handlers () at /lib64/libc.so.6 #9 0x00007fffdbb85235 in () at /lib64/libc.so.6 #10 0x00005555558d1b39 in testdev_write (testdev=0x5555566aa0a0) at /home/drjones/code/qemu/backends/testdev.c:71 #11 0x00005555558d1b39 in testdev_write (chr=<optimized out>, buf=0x7fffc343fd9a "", len=0) at /home/drjones/code/qemu/backends/testdev.c:95 #12 0x00005555558adced in qemu_chr_fe_write (s=0x5555566aa0e0, buf=buf@entry=0x7fffc343fd98 "0q", len=len@entry=2) at /home/drjones/code/qemu/qemu-char.c:282 Instead of using a atexit() handler, only run the chardev cleanup as initially proposed at the end of main(), where there are less chances (hic) of conflicts or other races.

2016-07-13net: do not use atexit for cleanupPaolo Bonzini
This will be necessary in the next patch, which stops using atexit for character devices; without it, vhost-user and the redirector filter will cause a use-after-free. Relying on the ordering of atexit calls is also brittle, even now that both the network and chardev subsystems are using atexit. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Commit 0544edd88a "vl: smp_parse: cleanups" regressed any -smp config that left either cores or threads unspecified, and specified a topology supporting more cpus than the given online cpus. The correct way to calculate the missing parameter would be to use maxcpus, but it's too late to change that now. Restore the old way, which is to calculate it with the online cpus (as is still done), but then, if the result is zero, just set it to one.

2016-06-27qapi: Report support for -device cpu hotplug in query-machinesPeter Krempa
For management apps it's very useful to know whether the selected machine type supports cpu hotplug via the new -device approach. Using the presence of 'query-hotpluggable-cpus' alone is not enough as a witness. Add a property to 'MachineInfo' called 'hotpluggable-cpus' that will report the presence of this feature. Example of output: { "hotpluggable-cpus": false, "name": "mac99", "cpu-max": 1 }, { "hotpluggable-cpus": true, "name": "pseries-2.7", "is-default": true, "cpu-max": 255, "alias": "pseries" }, Signed-off-by: Peter Krempa <pkrempa@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Reviewed-by: Igor Mammedov <imammedo@redhat.com> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2016-06-20log: Fix qemu_set_log_filename() error handlingMarkus Armbruster
When qemu_set_log_filename() detects an invalid file name, it reports an error, closes the log file (if any), and starts logging to stderr (unless daemonized or nothing is being logged). This is wrong. Asking for an invalid log file on the command line should be fatal. Asking for one in the monitor should fail without messing up an existing logfile. Fix by converting qemu_set_log_filename() to Error. Pass it &error_fatal, except for hmp_logfile report errors. This also permits testing without a subprocess, so do that.

2016-06-16vl.c: Add '-L help' which lists data dirs.Richard W.M. Jones
QEMU compiles a list of data directories from various sources. When consuming a QEMU binary it's useful to be able to get this list of data directories: a primary reason is so you can list what BIOSes or keymaps ship with this version of QEMU. However without reproducing the method that QEMU uses internally, it's not possible to get the list of data directories. This commit adds a simple '-L help' option that just lists out the data directories as qemu calculates them: $ ./x86_64-softmmu/qemu-system-x86_64 -L help /home/rjones/d/qemu/pc-bios /usr/local/share/qemu $ ./x86_64-softmmu/qemu-system-x86_64 -L /tmp -L help /tmp /home/rjones/d/qemu/pc-bios /usr/local/share/qemu Signed-off-by: Richard W.M.

The only case where DT_SDL is used outside a #ifdef CONFIG_SDL block is in the no_frame/alt_grab/ctrl_grab check. That means the only user-visible change is that we will start printing a warning if the SDL-specific options are used in Cocoa mode. This is a bugfix, because no_frame/alt_grab/ctrl_grab are not used by Cocoa code.

2016-04-28qom: -object error messages lost location, restore itMarkus Armbruster
qemu_opts_foreach() runs its callback with the error location set to the option's location. Any errors the callback reports use the option's location automatically. Commit 90998d5 moved the actual error reporting from "inside" qemu_opts_foreach() to after it. Here's a typical hunk: if (qemu_opts_foreach(qemu_find_opts("object"), - object_create, - object_create_initial, NULL)) { + user_creatable_add_opts_foreach, + object_create_initial, &err)) { + error_report_err(err); exit(1); } Before, object_create() reports from within qemu_opts_foreach(), using the option's location. Afterwards, we do it after qemu_opts_foreach(), using whatever location happens to be current there. Commonly a "none" location. This is because Error objects don't have location information. Problematic. Reproducer: $ qemu-system-x86_64 -nodefaults -display none -object secret,id=foo,foo=bar qemu-system-x86_64: Property '.foo' not found Note no location. This commit restores it: qemu-system-x86_64: -object secret,id=foo,foo=bar: Property '.foo' not found Note that the qemu_opts_foreach() bug just fixed could mask the bug here: if the location it leaves dangling hasn't been clobbered, yet, it's the correct one.

2016-04-07Sort the fw_cfg file listGerd Hoffmann
Entries are inserted in filename order instead of being appended to the end in case sorting is enabled. This will avoid any future issues of moving the file creation around, it doesn't matter what order they are created now, the will always be in filename order. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Added machine type handling for compatibility. This was a fairly complex change, this will preserve the order of fw_cfg for older versions no matter what order the firmware files actually come in. A list is kept of the correct legacy order and the entries will be inserted based upon their order in the list. Except that some entries are ordered (in a specific area of the list) based upon what order they appear on the command line. Special handling is added for those entries.

2016-04-05vl: Move cpu_synchronize_all_states() into qemu_system_reset()David Gibson
There are currently 3 calls to qemu_system_reset() in vl.c. Two of them are immediately preceded by a cpu_synchronize_all_states9) and the remaining one should be. The one which doesn't is the very first reset called directly from main(). Without a cpu_synchronize_all_states(), kvm_vcpu_dirty is false at this point from the earlier cpu_synchronize_all_post_init(). That's incorrect because the reset path is quite likely to update the CPU state, and that updated state should be pushed back to KVM, not overwritten with stale data pushed to KVM immediately after init. This patch moves the call to cpu_synchronize_all_states() into qemu_system_reset() for safety, so it is always called. AFAICT this should be safe for the handful of callers outside vl.c - these all appear to be in places where the cpu state is already synchronized so the extra call will be a no-op.
