Why: Enable CI validation on ARM architectures so platform-specific regressions are caught before merge. arm64 uses native GitHub runners; armhf uses QEMU because GitHub does not offer 32-bit ARM runners. Network namespace tests may fail under QEMU where the mount syscall is not properly emulated. Impact: - New arm_CI job runs on armhf and arm64 when relevant files change. - arm64 uses native ubuntu-24.04-arm runner; armhf uses QEMU on x64. - Netns tests skip gracefully (exit 77) if ip netns add fails. Before: - No ARM CI; netns tests could fail with cryptic errors under QEMU. After: - arm_CI: armhf (QEMU, reduced test set) and arm64 (native, expanded tests, ASan). - require_netns_capable() in diag.sh; netns tests call it and skip when unavailable. - ratelimit double-free fixed in ratelimit.c. - skip_ASAN() in diag.sh; empty-hostname, omfile-read-only* skip when ASan enabled (LD_PRELOAD/read-only behavior conflicts). Technical Overview: - Add arm_CI job to run_checks.yml: matrix over armhf/arm64. armhf: runs-on ubuntu-24.04, QEMU + Docker Buildx, reduced configure (disable-default-tests, many modules disabled). arm64: runs-on ubuntu-24.04-arm (native), expanded configure (default tests, gnutls, relp, imfile, etc.). Conditional QEMU setup only for armhf. - Add devtools/ci/Dockerfile.arm: Ubuntu 24.04 with build tools, gnutls, libestr, libfastjson, zlib, iproute2, libgcrypt, librelp, uuid, libyaml (for arm64 expanded build). - Add require_netns_capable() to diag.sh; use in imtcp-netns.sh, uxsock_multiple_netns.sh, tcp_forwarding_ns_tpl.sh. - Add skip_ASAN() to diag.sh; use in empty-hostname.sh, omfile-read-only.sh, omfile-read-only-errmsg.sh. - Add devtools/ci/Dockerfile.arm to arm_CI changed-files filter. - Quote $GITHUB_OUTPUT and $GITHUB_STEP_SUMMARY in clang static analyzer steps. - Fix double-free in ratelimit.c: shared->name is the hashtable key, freed by hashtable_destroy; remove redundant free(shared->name) in ratelimitFreeShared.

# This tests basic omuxsock functionality with namespaces.
|
|
# Multiple socket receivers are started which sends all data
|
|
# to an output file, then a rsyslog instance is started which
|
|
# generates messages and sends them to multiple unix sockets.
|
|
# Multiple socket types are being used.
|
|
# Based on uxsock_simple.sh added 2010-08-06 by Rgerhards
|
|
# Updated 2025-04-16 for abstract sockets and multiple socket
|
|
# types.
