Paolo Bonzini c45a70d8c2 device-plug-test: use qtest_qmp to send the device_del command
Simplify the code now that events are buffered.  There is no need
anymore to separate sending the command and retrieving the response.

Maxim Levitsky 5e34005571 qtest: remove qtest_qmp_receive_success
The purpose of qtest_qmp_receive_success was mostly to process events
that arrived between the issueing of a command and the "return"
line from QMP.  This is now handled by the buffering of events
that libqtest performs automatically.

Maxim Levitsky c22045bfe6 qtest: Reintroduce qtest_qmp_receive with QMP event buffering
The new qtest_qmp_receive buffers all the received qmp events, allowing
qtest_qmp_eventwait_ref to return them.

This is intended to solve the race in regard to ordering of qmp events
vs qmp responses, as soon as the callers start using the new interface.

In addition to that, define qtest_qmp_event_ref a function which only scans
the buffer that qtest_qmp_receive stores the events to.  This is intended
for callers that are only interested in events that were received during
the last call to the qtest_qmp_receive.

Maxim Levitsky 1c3e2a38de qtest: rename qtest_qmp_receive to qtest_qmp_receive_dict
In the next patch a new version of qtest_qmp_receive will be
reintroduced that will buffer received qmp events for later
consumption in qtest_qmp_eventwait_ref

No functional change intended.

Paolo Bonzini d9f24bf572 exec: split out non-softmmu-specific parts
Over the years, most parts of exec.c that were not specific to softmmu
have been moved to accel/tcg; what's left is mostly the low-level part
of the memory API, which includes RAMBlock and AddressSpaceDispatch.
However exec.c also hosts 4-500 lines of code for the target specific
parts of the CPU QOM object, plus a few functions for user-mode
emulation that do not have a better place (they are not TCG-specific so
accel/tcg/user-exec.c is not a good place either).

Move these parts to a new file, so that exec.c can be moved to
softmmu/physmem.c.

Philippe Mathieu-Daudé 8d0bceba24 hw/nvram: Always register FW_CFG_DATA_GENERATOR_INTERFACE
While the FW_CFG_DATA_GENERATOR_INTERFACE is only consumed
by a device only available using system-mode (fw_cfg), it is
implemented by a crypto component (tls-cipher-suites) which
is always available when crypto is used.

Commit 69699f3055 introduced the following error in the
qemu-storage-daemon binary:

  $ echo -e \
    '{"execute": "qmp_capabilities"}\r\n{"execute": "qom-list-types"}\r\n{"execute": "quit"}\r\n' \
    | storage-daemon/qemu-storage-daemon --chardev stdio,id=qmp0  --monitor qmp0
  {"QMP": {"version": {"qemu": {"micro": 50, "minor": 1, "major": 5}, "package": ""}, "capabilities": ["oob"]}}
  {"return": {}}
  missing interface 'fw_cfg-data-generator' for object 'tls-creds'
  Aborted (core dumped)

Since QOM dependencies are resolved at runtime, this issue
could not be triggered at linktime, and we don't have test
running the qemu-storage-daemon binary.

Fix by always registering the QOM interface.

Stefan Hajnoczi ebf101955c virtiofsd: avoid /proc/self/fd tempdir
In order to prevent /proc/self/fd escapes a temporary directory is
created where /proc/self/fd is bind-mounted. This doesn't work on
read-only file systems.

Avoid the temporary directory by bind-mounting /proc/self/fd over /proc.
This does not affect other processes since we remounted / with MS_REC |
MS_SLAVE. /proc must exist and virtiofsd does not use it so it's safe to
do this.

Path traversal can be tested with the following function:

  static void test_proc_fd_escape(struct lo_data *lo)
  {
      int fd;
      int level = 0;
      ino_t last_ino = 0;

      fd = lo->proc_self_fd;
      for (;;) {
          struct stat st;

          if (fstat(fd, &st) != 0) {
              perror("fstat");
              return;
          }
          if (last_ino && st.st_ino == last_ino) {
              fprintf(stderr, "inode number unchanged, stopping\n");
              return;
          }
          last_ino = st.st_ino;

          fprintf(stderr, "Level %d dev %lu ino %lu\n", level,
                  (unsigned long)st.st_dev,
                  (unsigned long)last_ino);
          fd = openat(fd, "..", O_PATH | O_DIRECTORY | O_NOFOLLOW);
          level++;
      }
  }

Before and after this patch only Level 0 is displayed. Without
/proc/self/fd bind-mount protection it is possible to traverse parent
directories.

names.

_top and _bottom also need to stay standard methods because some users
override the method and need to use `self`. Tell pylint to shush.

Make the file handling here just a tiny bit more idiomatic.
(I realize this is heavily subjective.)

Use exist_ok=True for os.makedirs and remove the exception,
use fdopen() to wrap the file descriptor in a File-like object,
and use a context manager for managing the file pointer.

John Snow f5d4361cda qapi/source.py: add type hint annotations
Annotations do not change runtime behavior.
This commit *only* adds annotations.

A note on typing of __init__: mypy requires init functions with no
parameters to document a return type of None to be considered fully
typed. In the case when there are input parameters, None may be omitted.

Since __init__ may never return any value, it is preferred to omit the
return annotation whenever possible.
