2015-03-19raw-posix: Deprecate host floppy passthroughMarkus Armbruster5-5/+9
Raise your hand if you have a physical floppy drive in a computer you've powered on in 2015. Okay, I see we got a few weirdos in the audience. That's okay, weirdos are welcome here. Kidding aside, media change detection doesn't fully work, isn't going to be fixed, and floppy passthrough just isn't earning its keep anymore. Deprecate block driver host_floppy now, so we can drop it after a grace period.

2015-03-19hmp: Fix definition of command quitMarkus Armbruster1-1/+0
The command handler is a union of two function types. If cmd->user_print is set, handle_user_command() calls cmd->mhandler.cmd_new(), else cmd->mhandler.cmd(). Command definitions must therefore either set both user_print() and mhandler.cmd_new(), or only mhandler.cmd(). quit's sets user_print and mhandler.cmd(). handle_user_command() calls hmp_quit() through mhandler.cmd_new() rather than mhandler.cmd(), i.e. through a function pointer with a different type. Broken in commit 7a7f325, v1.0. Works in practice because hmp_quit() doesn't use its arguments, and handle_user_command() ignores its function value.

2015-03-18profiler: Reenable built-in profilerAlexey Kardashevskiy3-7/+6
2ed1ebcf6 "timer: replace time() with QEMU_CLOCK_HOST" broke compile when configured with --enable-profiler. Turned out the profiler has been broken for a while. This does s/qemu_time/tcg_time/ as the profiler only works in a TCG mode. This also fixes the compile error. This changes profile_getclock() to return nanoseconds rather than CPU ticks as the "profile" HMP command prints seconds and there is no platform-independent way to get ticks-per-second rate. Since TCG is quite slow and get_clock() returns nanoseconds (fine enough), this should not affect precision much. This removes unused qemu_time_start and tlb_flush_time.

2015-03-18qemu-nbd: fork() can failMax Reitz1-1/+3
It is very unlikely, but it is possible. Signed-off-by: Max Reitz <mreitz@redhat.com> Message-Id: <1424887718-10800-10-git-send-email-mreitz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2015-03-18nbd: Pass return value from nbd_handle_list()Max Reitz1-3/+4
While it does not make a difference in practice, nbd_receive_options() generally returns -errno, so it should do that here as well; and the easiest way to achieve this is by passing on the value returned by nbd_handle_list().

2015-03-18nbd: Fix nbd_establish_connection()'s return valueMax Reitz1-1/+1
unix_connect_opts() and inet_connect_opts() do not necessarily set errno (if at all); therefore, nbd_establish_connection() should not literally return -errno on error.

2015-03-18qemu-nbd: Detect unused partitions by system == 0Max Reitz1-2/+4
Unused partitions do not necessarily have a total sector count of 0 (although they should have), but they always do have the system field set to 0, so use that for testing whether a partition is in use rather than the sector count field alone.
