Andrew Cooper 83754331a7 CI: Remove useless/misleading randconfig jobs
Randconfig builds pick CONFIG_DEBUG with 50% probability.  Therefore
$foo{,-debug}-randconfig are just two equivalent jobs with misleading names.

Furthermore, arm64 has randconfig jobs for both Alpine and Bookworm; Both
environments use GCC 12.2, so we have 4 equivalent jobs.  Delete 3 of them.

This leaves us with 4 primary randconfig jobs:

  gitlab-ci/build.yaml:381:debian-bookworm-gcc-arm32-randconfig:
  gitlab-ci/build.yaml:429:alpine-3.18-gcc-arm64-randconfig:
  gitlab-ci/build.yaml:495:archlinux-current-gcc-riscv64-randconfig:
  gitlab-ci/build.yaml:640:debian-bookworm-gcc-randconfig:

as PPC64 doesn't want randconfig right now, and buster-gcc-ibt is a special
job with a custom compiler.

Andrew Cooper 3420cc1a50 CI: Fix CONTAINER_UID0=1 scripts/containerize
Right now, most build containers use root.  Archlinux, Fedora and Yocto set up
a regular user called `user`.

For those containers, trying to containerize as root fails, because
CONTAINER_UID0=1 does nothing, whereas CONTAINER_UID0=0 forces the user away
from root.

To make CONTAINER_UID0=1 work reliably, force to root if requested.

Andrew Cooper d49ba6bf8f build: Drop xorg-x11 as a build dependency
The history on this one is complicated.  The note to README was added in
commit 1f95747a4f ("Add openssl-dev and xorg-x11-dev to README") in 2007.

At the time, there was a vendered version of Qemu in xen.git with a local
modification using <X11/keysymdef.h> to access the monitor console over VNC.

The final reference to keysymdef.h was dropped in commit 85896a7c4d ("build:
add autoconf to replace custom checks in tools/check") in 2012.  The next
prior mention was in 2009 with commit a8ccb671c3 ("tools: fix x11 check")
noting that x11 was not a direct dependcy of Xen; it was transitive through
SDL for Qemu for source-based distros.

It appears there may have been other unspecified dependencies on xorg,
e.g. the use of lndir by unmodified_drivers which are no longer relevant
either.

These days its only the Debian based dockerfiles which install xorg-x11, and
Qemu builds fine in these and others without x11.

Andrew Cooper c2a66d0b58 CI: Rework the CentOS7 container
CentOS 7 is fully End-of-life as of 2024-06-30, and the Yum repo configuration
points at URLs which have become non-existent.

First, start by using a heredoc RUN for legibility.  It's important to use
`set -e` to offset the fact that we're no longer chaining every command
together with an &&.

Also, because we're using a single RUN command to perform all RPM operations,
we no longer need to work around the OverlayFS bug.

Adjust the CentOS-*.repo files to point at vault.centos.org.  This also
involves swapping mirrorlist= for baseurl= in the yum config.

Use a minor bashism to express the dependenices more coherently, and identify
why we have certain dependencies.  Some adjustments are:

 * We need bzip2-devel for the dombuilder.  bzip2 needs retaining stubdom or
   `tar` fails to unpack the .bz2 archives.
 * {lzo,lz4,ztd}-devel are new optional dependency since the last time this
   package list was refreshed.
 * openssl-devel hasn't been a dependency since Xen 4.6.
 * We long ago ceased being able to build Qemu and SeaBIOS in this container,
   so drop their dependencies too.

Andrew Cooper aa2b6e4d84 CI: Formalise the use of heredocs
Commit b5739330d7 introduced the use of heredocs in the jessie/stretch
dockerfiles.

It turns out this was introduced by BuildKit in 2018 along with a
standardisation of Dockerfile syntax, and has subsequently been adopted by the
docker community.

Annotate all dockerfiles with a statement of the syntax in use, and extend
README.md details including how to activate BuildKit when it's available but
off by default.

This allows the containers to be rebuilt following commit a0e29b3163 ("CI:

MISRA C Rule 20.7 states: "Expressions resulting from the expansion
of macro parameters shall be enclosed in parentheses".

The local helpers GRP2 and XADD in the x86 emulator use their first
argument as the constant expression for a case label. This pattern

Rule 21.2 reports identifiers reserved for the C and POSIX standard
libraries: or, and, not and xor are reserved identifiers because they
constitute alternate spellings for the corresponding operators (they are
defined as macros by iso646.h); however Xen doesn't use standard library
headers, so there is no risk of overlap.

This addresses violations arising from x86_emulate/x86_emulate.c, where
label statements named as or, and and xor appear.

Nicola Vetrini c2d5e63c73 xen: fix MISRA regressions on rule 20.9 and 20.12
Commit ea59e7d780 ("xen/bitops: Cleanup and new infrastructure ahead of
rearrangements") introduced new violations on previously clean rules 20.9 and
20.12 (clean on ARM only, right now).

The first is introduced because CONFIG_CC_IS_CLANG in xen/self-tests.h is not
defined in the configuration under analysis. Using "defined()" instead avoids
relying on the preprocessor's behaviour upon encountering an undedfined identifier
and addresses the violation.

The violation of Rule 20.12 is due to "val" being used both as an ordinary argument
in macro RUNTIME_CHECK, and as a stringification operator.

Disable unnecessary configs for two cases:
1. By utilizing EXTRA_FIXED_RANDCONFIG for randconfig builds (GitLab CI jobs).
2. By using tiny64_defconfig for non-randconfig builds.

Only configs which lead to compilation issues were disabled.

Remove lines related to disablement of configs which aren't affected
compilation:
 -# CONFIG_SCHED_CREDIT is not set
 -# CONFIG_SCHED_RTDS is not set
 -# CONFIG_SCHED_NULL is not set
 -# CONFIG_SCHED_ARINC653 is not set
 -# CONFIG_TRACEBUFFER is not set
 -# CONFIG_HYPFS is not set
 -# CONFIG_SPECULATIVE_HARDEN_ARRAY is not set

Update argo.c to include asm/p2m.h directly, rather than on a transitive
dependency through asm/domain.h Update asm/p2m.h to include xen/errno.h,
rather than rely on it having included already.

CONFIG_XSM=n as it requires an introduction of:
* boot_module_find_by_kind()
* BOOTMOD_XSM
* struct bootmodule
* copy_from_paddr()
The mentioned things aren't introduced now.

CONFIG_BOOT_TIME_CPUPOOLS requires an introduction of cpu_physical_id() and
acpi_disabled, so it is disabled for now.

PERF_COUNTERS requires asm/perf.h and asm/perfc-defn.h, so it is
also disabled for now, as RISC-V hasn't introduced this headers yet.

LIVEPATCH isn't ready for RISC-V too and it can be overriden by randconfig,
so to avoid compilation errors for randconfig it is disabled for now.

Simone Ballarin 4edbbcd0c0 automation/eclair: reorganize pipelines
Introduce accepted_guidelines.sh: a script to autogenerate the
configuration file accepted.ecl from docs/misra/rules.rst which enables
all accepted guidelines.

Introduce monitored.ecl: a manual selection of accepted guidelines
which are clean or almost clean, it is intended to be used for the
analyses triggered by commits.

Reorganize tagging.ecl:
  -Remove "accepted" tags: keeping track of accepted guidelines tagging
   them as "accepted" in the configuration file tagging.ecl is no
   longer needed since docs/rules.rst is keeping track of them.
  -Tag more guidelines as clean.

Reorganize eclair pipelines:
  - Set1, Set2, Set3 are now obsolete: remove the corresponding
    pipelines and ecl files.
  - Amend scheduled eclair pipeline to use accepted.ecl.
  - Amend triggered eclair pipeline to use monitored.ecl.

Rename and improve action_check_clean_regressions.sh to print a
diagnostic in case a commit introduces a violation of a clean guideline.

An example of diagnostic is the following:

Failure: 13 regressions found for clean guidelines
  service MC3R1.R8.2: (required) Function types shall be in prototype form with named parameters:
   violation: 13

Michal Orzel 31d6b5b4a7 automation: Add arm64 test for running Xen with GICv3
At the moment, all the Arm64 Qemu tests use GICv2 which is the default
GIC version used by Qemu. Improve the coverage by adding a new test in
which Qemu will be configured to have GICv3.

Rename host device tree name to "virt.dtb" to be GIC version agnostic.
Use "gic-version" Qemu option to select the version to use. Unless the
test variant is set to "gicv3", version 2 will be used.

Michal Orzel c05b97fc7a automation: Drop some of the non-debug variants of the same Arm jobs
To save some bandwith that can be later on used to increase the test
coverage by adding new tests, drop the following non-debug test/build
jobs existing in both debug and non-debug variants:
 - static memory (arm64, arm32)
 - static shared memory (arm64)
 - static heap (arm64)
 - boot cpupools (arm64)
 - gzip (arm32)

More generic tests existing in both variants were left unmodified.

Nicola Vetrini 93d6e6efa8 automation/eclair_analysis: substitute deprecated service STD.emptrecd
The ECLAIR service STD.emptrecd (which checks for empty structures) is being
deprecated; hence, as a preventive measure, STD.anonstct (which checks for
structures with no named members, an UB in C99) is used here; the latter being
a more general case than the previous one, this change does not affect the
analysis. This new service is already supported by the current version of
ECLAIR.

No functional change.

Nicola Vetrini 5495ed0cd2 eclair_analysis: deviate x86 emulator for Rule 16.2
MISRA C Rule 16.2 states:
"A switch label shall only be used when the most closely-enclosing
compound statement is the body of a switch statement".

Since complying with this rule of the x86 emulator would lead to
a lot of code duplication, it is deemed better to exempt those
files for this guideline.

No functional change.
