[PULL 02/17] qtest: use correct boolean type for failover property

[Thomas Huth]

From: Daniel P. Berrangé <berrange@redhat.com>

QMP device_add does not historically validate the parameter types.
At some point it will likely change to enforce correct types, to
match behaviour of -device. The failover property is expected to
be a boolean in JSON.

[PULL 03/17] Revert "netdev: set timeout depending on loadavg"

[Thomas Huth]

From: Daniel P. Berrangé <berrange@redhat.com>

This reverts commit cadfc7293977ecadc2d6c48d7cffc553ed2f85f1.

The test was not timing out because of slow execution. It was
timing out due to a race condition leading to the client QEMU
attempting (and fatally failing) to connect before the server
QEMU was listening.

[PULL 05/17] Revert "tests/qtest/netdev-socket: Raise connection timeout to 120 seconds"

[Thomas Huth]

From: Daniel P. Berrangé <berrange@redhat.com>

This reverts commit 0daaf2761f6d268ffaa2d01d450e202e127452b1.

The test was not timing out because of slow execution. It was
timing out due to a race condition leading to the client QEMU
attempting (and fatally failing) to connect before the server
QEMU was listening.

[PULL 06/17] net: add explicit info about connecting/listening state

[Thomas Huth]

From: Daniel P. Berrangé <berrange@redhat.com>

When running 'info network', if the stream backend is still in
the process of connecting, or waiting for an incoming connection,
no information is displayed.

There is also no way to distinguish whether the server is still
in the process of setting up the listener socket, or whether it
is ready to accept incoming client connections.

This leads to a race condition in the netdev-socket qtest which
launches a server process followed by a client process. Under
high load conditions it is possible for the client to attempt
to connect before the server is accepting clients. For the
scenarios which do not set the 'reconnect' option, this opens
up a race which can lead to the test scenario failing to reach
the expected state.

Now that 'info network' can distinguish between initialization
phase and the listening phase, the netdev-socket qtest will
correctly synchronize, such that the client QEMU is not spawned
until the server is ready.

This should solve the non-deterministic failures seen with the
netdev-socket qtest.

[PULL 07/17] net: handle QIOTask completion to report useful error message

[Thomas Huth]

From: Daniel P. Berrangé <berrange@redhat.com>

The network stream backend uses the async QIO socket APIs for listening
and connecting sockets. It does not check the task object completion
status, however, instead just looking at whether the socket FD is -1
or not.

By checking the task completion, we can set a useful error message for
users instead of the non-actionable "connection error" string.

eg so users will see:

(qemu) info network
net: index=0,type=stream,error: Failed to connect to '/foo.unix': No such file or directory

[PULL 11/17] target/s390x/kvm/pv: Provide some more useful information if decryption fails

[Thomas Huth]

It's a common scenario to copy guest images from one host to another
to run the guest on the other machine. This (of course) does not work
with "secure execution" guests since they are encrypted with one certain
host key. However, if you still (accidentally) do it, you only get a
very user-unfriendly error message that looks like this:

 qemu-system-s390x: KVM PV command 2 (KVM_PV_SET_SEC_PARMS) failed:
  header rc 108 rrc 5 IOCTL rc: -22

Let's provide at least a somewhat nicer hint to the users so that they
are able to figure out what might have gone wrong.

[PULL 12/17] hw/s390x/ccw: Replace basename() with g_path_get_basename()

[Thomas Huth]

From: Zhao Liu <zhao1.liu@intel.com>

g_path_get_basename() is a portable utility function that has the
advantage of not modifying the string argument, so it should be
preferred over basename().

And also to avoid potential compile breakage with the Musl C library
similar to [1], replace basename() with g_path_get_basename().

[PULL 13/17] hw/s390x/ccw: Replace dirname() with g_path_get_dirname()

[Thomas Huth]

From: Zhao Liu <zhao1.liu@intel.com>

As commit 3e015d815b3f ("use g_path_get_basename instead of basename")
said, g_path_get_dirname() should be preferred over dirname() since
the former is a portable utility function that has the advantage of not
modifying the string argument.

Replace dirname() with g_path_get_dirname().

[PULL 14/17] scripts/checkpatch: Support codespell checking

[Thomas Huth]

From: Zhao Liu <zhao1.liu@intel.com>

Add two spelling check options (--codespell and --codespellfile) to
enhance spelling check through dictionary, which copied the Linux
kernel's implementation in checkpatch.pl.

This check uses the dictionary at "/usr/share/codespell/dictionary.txt"
by default, if there is no dictionary specified under this path, it
will look for the dictionary of python3's codespell (This requires user
to add python3's path in environment variable $PATH, and to install
codespell by "pip install codespell").

[PULL 16/17] tests/tcg/s390x: Test LOAD ADDRESS EXTENDED

[Thomas Huth]

From: Ilya Leoshkevich <iii@linux.ibm.com>

Add a small test to prevent regressions. Userspace runs in primary
mode, so LAE should always set the access register to 0.

[PULL 17/17] .gitlab-ci.d/buildtest.yml: Work around htags bug when environment is large

[Thomas Huth]

From: Peter Maydell <peter.maydell@linaro.org>

Sometimes the CI "pages" job fails with a message like this from
htags:

$ htags -anT --tree-view=filetree -m qemu_init -t "Welcome to the QEMU sourcecode"
htags: Negative exec line limit = -371

This is due to a bug in hflags where if the environment is too large it
falls over:
https://lists.gnu.org/archive/html/bug-global/2024-01/msg00000.html

This happens to us because GitLab CI puts the commit message of the
commit under test into the CI_COMMIT_MESSAGE and/or CI_COMMIT_TAG_MESSAGE
environment variables, so the job will fail if the commit happens to
have a verbose commit message.

Work around the htags bug by unsetting these variables while running
htags.
