3600604667 scripts/qmp: delete 'qmp' script
This script has not seen a patch that was specifically for this script
since it was moved to this location in 2013, and I doubt it is used. It
uses "man qmp" for its help message, which does not exist. It also
presumes there is a manual page for qmp-XXX, for each defined qmp
command XXX. I don't think that's true.

The format it expects arguments in is something like:

block-dirty-bitmap-add --node=foo --name=bar

and has no capacity to support nested JSON arguments, either.

Most developers use either qmp-shell or socat (or pasting JSON directly
into qmp stdio), so this duplication and additional alternate syntax is
not helpful.

Remove it. Leave a breadcrumb script just in case, to be removed next
release cycle.

0395b19438 tests/acceptance: pick a random gdb port for reverse debugging
Currently the test randomly fails if you are using a shared machine
due to contention on the well known port 1234. We can ameliorate this
a bit by picking a random non-ephemeral port although it doesn't
totally avoid the problem. While we could use a totally unique socket
address for debugging it is fiddly to probe for gdb support. While gdb
socket debugging is not yet ubiquitous this a sub-optimal but workable
option.

c93a656f7b tests/acceptance: Add virtiofs_submounts.py
This test invokes several shell scripts to create a random directory
tree full of submounts, and then check in the VM whether every submount
has its own ID and the structure looks as expected.

(Note that the test scripts must be non-executable, so Avocado will not
try to execute them as if they were tests on their own, too.)

Because at this commit's date it is unlikely that the Linux kernel on
the image provided by boot_linux.py supports submounts in virtio-fs, the
test will be cancelled if no custom Linux binary is provided through the
vmlinuz parameter.  (The on-image kernel can be used by providing an
empty string via vmlinuz=.)

So, invoking the test can be done as follows:
$ avocado run \
    tests/acceptance/virtiofs_submounts.py \
    -p vmlinuz=/path/to/linux/build/arch/x86/boot/bzImage

This test requires root privileges (through passwordless sudo -n),
because at this point, virtiofsd requires them.  (If you have a
timestamp_timeout period for sudoers (e.g. the default of 5 min), you
can provide this by executing something like "sudo true" before invoking
Avocado.)

08dce386e7 virtiofsd: Announce sub-mount points
Whenever we encounter a directory with an st_dev that differs from that
of its parent, we set the FUSE_ATTR_SUBMOUNT flag so the guest can
create a submount for it.

Make this behavior optional, so submounts are only announced to the
guest with the announce_submounts option.  Some users may prefer the
current behavior, so that the guest learns nothing about the host mount
structure.

eba8b096c1 virtiofsd: Store every lo_inode's parent_dev
We want to detect mount points in the shared tree.  We report them to
the guest by setting the FUSE_ATTR_SUBMOUNT flag in fuse_attr.flags, but
because the FUSE client will create a submount for every directory that
has this flag set, we must do this only for the actual mount points.

We can detect mount points by comparing a directory's st_dev with its
parent's st_dev.  To be able to do so, we need to store the parent's
st_dev in the lo_inode object.

Note that mount points need not necessarily be directories; a single
file can be a mount point as well.  However, for the sake of simplicity
let us ignore any non-directory mount points for now.

The mapping rule system implemented in the last few patches is
extremely flexible, but not easy to use.  Add a simple
'map' type as a sprinkling of sugar to make it easy.

e.g.

  -o xattrmap=":map::user.virtiofs.:"

would be sufficient to prefix all xattr's
or

  -o xattrmap=":map:trusted.:user.virtiofs.:"

would just prefix 'trusted.' xattr's and leave
everything else alone.

6084633dff tools/virtiofsd: xattr name mappings: Add option
Add an option to define mappings of xattr names so that
the client and server filesystems see different views.
This can be used to have different SELinux mappings as
seen by the guest, to run the virtiofsd with less privileges
(e.g. in a case where it can't set trusted/system/security
xattrs but you want the guest to be able to), or to isolate
multiple users of the same name; e.g. trusted attributes
used by stacking overlayfs.

A mapping engine is used with 3 simple rules; the rules can
be combined to allow most useful mapping scenarios.
The ruleset is defined by -o xattrmap='rules...'.

This patch doesn't use the rule maps yet.

06844584b6 virtiofsd: add container-friendly -o sandbox=chroot option
virtiofsd cannot run in a container because CAP_SYS_ADMIN is required to
create namespaces.

Introduce a weaker sandbox mode that is sufficient in container
environments because the container runtime already sets up namespaces.
Use chroot to restrict path traversal to the shared directory.

virtiofsd loses the following:

1. Mount namespace. The process chroots to the shared directory but
   leaves the mounts in place. Seccomp rejects mount(2)/umount(2)
   syscalls.

2. Pid namespace. This should be fine because virtiofsd is the only
   process running in the container.

3. Network namespace. This should be fine because seccomp already
   rejects the connect(2) syscall, but an additional layer of security
   is lost. Container runtime-specific network security policies can be
   used drop network traffic (except for the vhost-user UNIX domain
   socket).

648b4823d9 trace/simple: Enable tracing on startup only if the user specifies a trace option
Tracing can be enabled at the command line or via the
monitor. Command-line trace options are recorded during
trace_opt_parse(), but tracing is not enabled until the various
front-ends later call trace_init_file(). If the user passes a trace
option on the command-line, remember that and enable tracing during
trace_init_file().  Otherwise, trace_init_file() should record the
trace file specified by the frontend and avoid enabling traces
until the user requests them via the monitor.

This fixes 1b7157be3a and also
db25d56c01, by allowing the user
to enable traces on the command line and also avoiding
unwanted trace-<pid> files when the user has not asked for them.

a47295014d migration-test: Only hide error if !QTEST_LOG
The errors are very useful when debugging qtest failures, especially when
QTEST_LOG=1 is set.  Let's allow override MigrateStart.hide_stderr when
QTEST_LOG=1 is specified, because that means the user wants to be verbose.

Not very nice to introduce the first QTEST_LOG env access in migration-test.c,
however it should be handy.  Without this patch, I was hacking error_report()
when debugging such errors.  Let's make things easier.

d246ea5039 migration/postcopy: Release fd before going into 'postcopy-pause'
Logically below race could trigger with the old code:

          test program                        migration thread
          ------------                        ----------------
       wait_until('postcopy-pause')
                                          postcopy_pause()
                                            set_state('postcopy-pause')
       do_postcopy_recover()
         arm s->to_dst_file with new fd
                                            release s->to_dst_file [1]

Here [1] could have released the just-installed recoverying channel.  Then the
migration could hang without really resuming.

Instead, it should be very safe to release the fd before setting the state into
'postcopy-pause', because there's no reason for any other thread to touch it
during 'postcopy-active'.

Dave reported a very rare postcopy recovery hang that the migration-test
program waited for the migration to complete in migrate_postcopy_complete().
We do suspect it's the same thing that we're gonna fix here.  Hard to tell.
However since we've noticed this, fix this irrelevant of the hang report.
