68406d1085 tests/unit: cleanups for test-io-channel-command
This test is hanging under heavy load when the two socats race while
trying to create the socket. I've tried various approaches to avoid
the race but it seems "creat=0" won't stop socat trying to create a
pipe if it executes first. In the end I just use a small sleep which
seems to be reliable enough on the load situations I've tried.

While I was there I also properly created a tmpdir for the socket to
live in which is cleaned up at the end of the test.

5bb0474778 block: Manipulate bs->file / bs->backing pointers in .attach/.detach
bs->file and bs->backing are a kind of duplication of part of
bs->children. But very useful diplication, so let's not drop them at
all:)

We should manage bs->file and bs->backing in same place, where we
manage bs->children, to keep them in sync.

Moreover, generic io paths are unprepared to BdrvChild without a bs, so
it's double good to clear bs->file / bs->backing when we detach the
child.

Detach is simple: if we detach bs->file or bs->backing child, just
set corresponding field to NULL.

Attach is a bit more complicated. But we still can precisely detect
should we set one of bs->file / bs->backing or not:

- if role is BDRV_CHILD_COW, we definitely deal with bs->backing
- else, if role is BDRV_CHILD_FILTERED (it must be also
  BDRV_CHILD_PRIMARY), it's a filtered child. Use
  bs->drv->filtered_child_is_backing to chose the pointer field to
  modify.
- else, if role is BDRV_CHILD_PRIMARY, we deal with bs->file
- in all other cases, it's neither bs->backing nor bs->file. It's some
  other child and we shouldn't care

OK. This change brings one more good thing: we can (and should) get rid
of all indirect pointers in the block-graph-change transactions:

bdrv_attach_child_common() stores BdrvChild** into transaction to clear
it on abort.

bdrv_attach_child_common() has two callers: bdrv_attach_child_noperm()
just pass-through this feature, bdrv_root_attach_child() doesn't need
the feature.

Look at bdrv_attach_child_noperm() callers:
  - bdrv_attach_child() doesn't need the feature
  - bdrv_set_file_or_backing_noperm() uses the feature to manage
    bs->file and bs->backing, we don't want it anymore
  - bdrv_append() uses the feature to manage bs->backing, again we
    don't want it anymore

So, we should drop this stuff! Great!

We could probably keep BdrvChild** argument to keep the int return
value, but it seems not worth the complexity.

Finally, we now set .file / .backing automatically in generic code and
want to restring setting them by hand outside of .attach/.detach.
So, this patch cleanups all remaining places where they were set.
To find such places I use:

  git grep '\->file ='
  git grep '\->backing ='
  git grep '&.*\<backing\>'
  git grep '&.*\<file\>'

1921b4f786 test-bdrv-graph-mod: fix filters to be filters
bdrv_pass_through is used as filter, even all node variables has
corresponding names. We want to append it, so it should be
backing-child-based filter like mirror_top.
So, in test_update_perm_tree, first child should be DATA, as we don't
want filters with two filtered children.

bdrv_exclusive_writer is used as a filter once. So it should be filter
anyway. We want to append it, so it should be backing-child-based
fitler too.

Make all FILTERED children to be PRIMARY as well. We are going to force
this rule by assertion soon.

Don't worry about setting bs->backing itself: in further commit we'll

code.

1dcea71979 test-bdrv-graph-mod: update test_parallel_perm_update test case
test_parallel_perm_update() does two things that we are going to
restrict in the near future:

1. It updates bs->file field by hand. bs->file will be managed
   automatically by generic code (together with bs->children list).

   Let's better refactor our "tricky" bds to have own state where one
   of children is linked as "selected".
   This also looks less "tricky", so avoid using this word.

2. It create FILTERED children that are not PRIMARY. Except for tests
   all FILTERED children in the Qemu block layer are always PRIMARY as
   well.  We are going to formalize this rule, so let's better use DATA
   children here.

3. It creates more than one FILTERED child, which is already abandoned
   in BDRV_CHILD_FILTERED's description.

While being here, update the picture to better correspond to the test
code.

f1018ea0a3 tests: avoid DOS line endings in PSK file
Using FILE * APIs for writing the PSK file results in translation from
UNIX to DOS line endings on Windows. When the crypto PSK code later
loads the credentials the stray \r will result in failure to load the
PSK credentials into GNUTLS.

Rather than switching the FILE* APIs to open in binary format, just
switch to the more concise g_file_set_contents API.

76f5148c21 tests/unit: make test-io-channel-command work on win32
This has been tested under msys2 & windows 11. I haven't tried to make
it work with other environments yet, but that should be enough to
validate the channel-command implementation anyway.

Here are the changes:
- drop tests/ from fifo/pipe path, to avoid directory issues
- use g_find_program() to lookup the socat executable (otherwise we
would need to change ChanneCommand to use G_SPAWN_SEARCH_PATH, and deal
with missing socat differently)
- skip the "echo" test when socat is missing as well

bb06b0143b tests/channel-helper: set blocking in main thread
The /io/channel/command/echo tests run the reader side and the writer
side with the same underlying command channel. Setting the blocking mode
of the fd/handles while the other end is already reading/writing may
create issues (deadlock in win32 when earlier attempt of this series
were using SetNamedPipeHandleState). Let's just do it before spawning
the threads to avoid further concurrency issues.

so it should not use "qtest.*" for temporary file names. Give
them better names instead, so that it clear where the temporary
files come from.

9bd4d3c2e3 job: remove unused functions
These public functions are not used anywhere, thus can be dropped.
Also, since this is the final job API that doesn't use AioContext
lock and replaces it with job_lock, adjust all remaining function
documentation to clearly specify if the job lock is taken or not.

Also document the locking requirements for a few functions
where the second version is not removed.

6f592e5aca job.c: enable job lock/unlock and remove Aiocontext locks
Change the job_{lock/unlock} and macros to use job_mutex.

Now that they are not nop anymore, remove the aiocontext
to avoid deadlocks.

Therefore:
- when possible, remove completely the aiocontext lock/unlock pair
- if it is used by some other function too, reduce the locking
  section as much as possible, leaving the job API outside.
- change AIO_WAIT_WHILE in AIO_WAIT_WHILE_UNLOCKED, since we
  are not using the aiocontext lock anymore

The only functions that still need the aiocontext lock are:
- the JobDriver callbacks, already documented in job.h
- job_cancel_sync() in replication.c is called with aio_context_lock
  taken, but now job is using AIO_WAIT_WHILE_UNLOCKED so we need to
  release the lock.

Reduce the locking section to only cover the callback invocation
and document the functions that take the AioContext lock,
to avoid taking it twice.

Also remove real_job_{lock/unlock}, as they are replaced by the
public functions.

191e7af394 jobs: use job locks also in the unit tests
Add missing job synchronization in the unit tests, with
explicit locks.

We are deliberately using _locked functions wrapped by a guard
instead of a normal call because the normal call will be removed
in future, as the only usage is limited to the tests.

In other words, if a function like job_pause() is/will be only used
in tests to avoid:

WITH_JOB_LOCK_GUARD(){
    job_pause_locked();
}

then it is not worth keeping job_pause(), and just use the guard.

Note: at this stage, job_{lock/unlock} and job lock guard macros
are *nop*.

582a098e6c qga: Replace 'blacklist' command line and config file options by 'block-rpcs'
Let's use a more appropriate wording for this command line and config
file option. The old ones are still accepted for compatibility reasons,
but marked as deprecated now so that it could be removed in a future
version of QEMU.

This change is based on earlier patches from Philippe Mathieu-Daudé,
with the idea for the new option name suggested by BALATON Zoltan.

And while we're at it, replace the "?" in the help text with "help"
since that does not have the problem of conflicting with the wildcard
character of the shells.

b3a58a6ae3 tests: unit: add NULL-pointer check
In CID 1432593, Coverity complains that the result of qdict_crumple()
might leak if it is not a dictionary.  This is not a practical concern
since the test would fail immediately with a NULL pointer dereference
in qdict_size().

However, it is not nice to depend on qdict_size() crashing, so add an
explicit assertion that that the crumpled object was indeed a dictionary.

test-visitor-serialization list tests is using an "if" to pick either the first
element of the list or the next one.  This was done presumably to mimic the
code that creates the list, which has to fill in either the head pointer
or the next pointer of the last element.  However, the code in the insert
phase is a pretty standard singly-linked list insertion, while the one
in the visit phase looks weird and even looks at the first item twice:
this is confusing because the test puts in 32 items and finishes with
an assertion that i == 33.

So, move the "else" step in a separate switch statement, and change
the do...while loop to a while, because cur_head has already been
initialized beforehand.

c4f8ce24de tests/unit: Replace g_memdup() by g_memdup2()
Per https://discourse.gnome.org/t/port-your-module-from-g-memdup-to-g-memdup2-now/5538

  The old API took the size of the memory to duplicate as a guint,
  whereas most memory functions take memory sizes as a gsize. This
  made it easy to accidentally pass a gsize to g_memdup(). For large
  values, that would lead to a silent truncation of the size from 64
  to 32 bits, and result in a heap area being returned which is
  significantly smaller than what the caller expects. This can likely
  be exploited in various modules to cause a heap buffer overflow.

Replace g_memdup() by the safer g_memdup2() wrapper.
