As all commands use the ADMIN queue, it is pointless to pass
it as argument each time. Remove the argument, and rename the
function as nvme_admin_cmd_sync() to make this new behavior

From the specification chapter 3.1.8 "AQA - Admin Queue Attributes"
the Admin Submission Queue Size field is a 0’s based value:
Admin Submission Queue Size (ASQS):
Defines the size of the Admin Submission Queue in entries.
Enabling a controller while this field is cleared to 00h
produces undefined results. The minimum size of the Admin
Submission Queue is two entries. The maximum size of the
Admin Submission Queue is 4096 entries.
This is a 0’s based value.
This bug has never been hit because the device initialization
uses a single command synchronously :)

The abstract socket namespace is a non-portable Linux extension. An
attempt to use it elsewhere should fail with ENOENT (the abstract
address looks like a "" pathname, which does not resolve). We report
this failure like
Failed to connect socket abc: No such file or directory
Tolerable, although ENOTSUP would be better.
However, introspection lies: it has @abstract regardless of host
support. Easy enough to fix: since Linux provides them since 2.2,
'if': 'defined(CONFIG_LINUX)' should do.
The above failure becomes
Parameter 'backend.data.addr.data.abstract' is unexpected
I consider this an improvement.

unix_listen_saddr() replaces empty @path by unique value. It obtains
the value by creating and deleting a unique temporary file with
mkstemp(). This is racy, as the comment explains. It's also entirely
undocumented as far as I can tell. Goes back to commit d247d25f18
"sockets: helper functions for qemu (Gerd Hoffman)", v0.10.0.
Since abstract socket addresses have no connection with filesystem
pathnames, making them up with mkstemp() seems inappropriate. Bypass

Commit 776b97d360 "qemu-sockets: add abstract UNIX domain socket

function returns a non-abstract socket address for abstract
sockets (wrong) with a null @path (also wrong; a non-optional QAPI str
member must never be null).
The null @path is due to confused code going back all the way to

An optional bool member of a QAPI struct can be false, true, or absent.
The previous commit demonstrated that socket_listen() and
socket_connect() are broken for absent @tight, and indeed QMP chardev-
add also defaults absent member @tight to false instead of true.
In C, QAPI members are represented by two fields, has_MEMBER and MEMBER.
We have:
has_MEMBER MEMBER
false true false
true true true
absent false false/ignore
When has_MEMBER is false, MEMBER should be set to false on write, and
ignored on read.
For QMP, the QAPI visitors handle absent @tight by setting both
@has_tight and @tight to false. unix_listen_saddr() and
unix_connect_saddr() however use @tight only, disregarding @has_tight.
This is wrong and means that absent @tight defaults to false whereas it
should default to true.
The same is true for @has_abstract, though @abstract defaults to
false and therefore has the same behavior for all of QMP, HMP and CLI.
Fix unix_listen_saddr() and unix_connect_saddr() to check
@has_abstract/@has_tight, and to default absent @tight to true.
However, this is only half of the story. HMP chardev-add and CLI
-chardev so far correctly defaulted @tight to true, but defaults to
false again with the above fix for HMP and CLI. In fact, the "tight"
and "abstract" options now break completely.
Digging deeper, we find that qemu_chr_parse_socket() also ignores
@has_tight, leaving it false when it sets @tight. That is also wrong,
but the two wrongs cancelled out. Fix qemu_chr_parse_socket() to set
@has_tight and @has_abstract; writing testcases for HMP and CLI is left
for another day.

The abstract sockets test spawns a thread to listen and accept, and a
second one to connect, with a sleep(1) in between to "ensure" the
former is listening when the latter tries to connect. Review fail.
Risks spurious test failure, say when a heavily loaded machine doesn't
schedule the first thread quickly enough. It's also slow.
Listen and accept in the main thread, and start the connect thread in
between. Look ma, no sleep! Run time drops from 2s wall clock to a

Add new commands to add and remove SSH public keys from
~/.ssh/authorized_keys.
I took a different approach for testing, including the unit tests right
with the code. I wanted to overwrite the function to get the user
details, I couldn't easily do that over QMP. Furthermore, I prefer
having unit tests very close to the code, and unit files that are domain
specific (commands-posix is too crowded already). FWIW, that
coding/testing style is Rust-style (where tests can or should even be
part of the documentation!).

The glib function was introduced in 2.64. It's a safer version of
getpwnam, and also simpler to use than getpwnam_r.
Currently, it's only use by the next patch in qemu-ga, which doesn't
(well well...) need the thread safety guarantees. Since the fallback
version is still unsafe, I would rather keep the _qemu postfix, to make
sure it's not being misused by mistake. When/if necessary, we can
implement a safer fallback and drop the _qemu suffix.

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.)

Whenever we encounter a directory with an st_dev or mount ID that
differs from that of its parent, we set the FUSE_ATTR_SUBMOUNT flag so
the guest can create a submount for it.
We only need to do so in lo_do_lookup(). The following functions return
a fuse_attr object:
- lo_create(), though fuse_reply_create(): Calls lo_do_lookup().
- lo_lookup(), though fuse_reply_entry(): Calls lo_do_lookup().
- lo_mknod_symlink(), through fuse_reply_entry(): Calls lo_do_lookup().
- lo_link(), through fuse_reply_entry(): Creating a link cannot create a
submount, so there is no need to check for it.
- lo_getattr(), through fuse_reply_attr(): Announcing submounts when the
node is first detected (at lookup) is sufficient. We do not need to
return the submount attribute later.
- lo_do_readdir(), through fuse_add_direntry_plus(): Calls
lo_do_lookup().
Make announcing submounts 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.
(announce_submounts is force-disabled when the guest does not present
the FUSE_SUBMOUNTS capability, or when there is no statx().)

Using st_dev is not sufficient to uniquely identify a mount: You can
mount the same device twice, but those are still separate trees, and
e.g. by mounting something else inside one of them, they may differ.
Using statx(), we can get a mount ID that uniquely identifies a mount.
If that is available, add it to the lo_inode key.
