fix(privileges): drop root before input and retain owned ICMP sockets (#639)
Open and own the required ICMP sockets before permanently dropping setuid root, then parse input without elevated identity. Close-on-exec socket ownership, shared IPv4/IPv6 dispatch and fault-injected identity/capability calls are covered. The owned fixture tests check deny/allow behavior without contacting external devices. Step 2/14 of the complete C17/native-correctness series. Base: the preceding series branch; merge/review in order so this PR shows only its own step. Earlier validation, before this review follow-up, in isolated copied snapshots on Linux arm64: - Clean GCC build and make check: 13 passed, 1 existing prerequisite skips, 0 failures. - ASan/UBSan: 12 passed, 2 existing privilege/allocator-interposition prerequisite skips, 0 failures; no sanitizer findings. - Production source/profile integrity verification against disposable MariaDB and loopback SNMP fixtures passed. - Release archive extracted into a separate source tree and built/tested out of tree; fuzz checks passed. Earlier local profiles retain source hashes for the copied validation tree; GitHub checks validate the published commit. No production database/device, host installation or live privilege change is part of validation. Existing prerequisite skips were retained; no test or finding was suppressed to obtain a pass. Series navigation: [Series index](https://github.com/Cacti/spine/pull/638); [previous step](https://github.com/Cacti/spine/pull/638). [Next step](https://github.com/Cacti/spine/pull/640). Review follow-up (2026-10-09): Restacked on the corrected preceding branches. The SNMP status fix is introduced in #638, the reindex/completion fixes in #640, and focused regression coverage in #650. Restacked tip validation: isolated Linux arm64 build and make check passed (18 passed, 1 setuid prerequisite skip, no failures). GitHub checks validate the updated published commits; earlier profile/archive/sanitizer evidence above belongs to the previous revisions. --------- Signed-off-by: Thomas Vincent <thomasvincent@gmail.com> |

refactor(core): add bounded native interfaces and polling contracts (#638)
Introduce bounded native interfaces and grouped runtime state, then link regression and fault contracts against the real poller implementations. The contracts capture CLI/configuration input, availability combinations, SNMP request/response ownership, script framing, reindexing, output persistence, worker completion and shutdown. This foundational change is larger because the shared interfaces and their existing production contracts must move together; later changes have separate review boundaries. Step 1/14 of the complete C17/native-correctness series. Base: develop. Earlier validation, before this review follow-up, in isolated copied snapshots on Linux arm64: - Clean GCC build and make check: 13 passed, 0 existing prerequisite skips, 0 failures. - ASan/UBSan: 12 passed, 1 existing privilege/allocator-interposition prerequisite skips, 0 failures; no sanitizer findings. - Production source/profile integrity verification against disposable MariaDB and loopback SNMP fixtures passed. - Release archive extracted into a separate source tree and built/tested out of tree; fuzz checks passed. Earlier local profiles retain source hashes for the copied validation tree; GitHub checks validate the published commit. No production database/device, host installation or live privilege change is part of validation. Existing prerequisite skips were retained; no test or finding was suppressed to obtain a pass. The worker contracts publish owned heap state and release it only after joining workers and restoring the runtime table. Coverage counters use atomic updates; cppcheck receives an explicit model of the fatal exit contract. Fixture images use public mirrors to avoid shared Docker Hub pull limits.

[build(ci): validate connectors time width and native C17 modules](https://github.com/Cacti/spine/pull/651) Review follow-up (2026-10-09): Publish the decoded GET/GETNEXT status back to the host so availability checks observe exception and missing-response failures, while preserving the legacy transport-success behavior for agent PDU errors. Updated step 1 snapshot: isolated Linux arm64 build and make check passed (13 passed, no skips or failures). The restacked tip passes all five clang-tidy gate regression tests and real clang-tidy analysis (26 reviewed baseline findings, no new findings). Actionlint and matching DCO trailers pass. The setuid test also passes when run in the separate disposable root container. GitHub checks validate the updated published commits; earlier profile/archive/sanitizer evidence above belongs to the previous revisions. --------- Signed-off-by: Thomas Vincent <thomasvincent@gmail.com> |

fix: extract core safety fixes from #597 (#621)
Extracted from #597 into a focused core correctness and memory-safety change. This checks startup allocations, bounds full log lines and query construction, frees settings result sets on NULL-row paths, caches the configured timestamp format, replaces advancing snprintf cursors with a bounded append contract, fixes remote batch boundary loss, and converts delimited hexadecimal OctetStrings without overflow. poller_output and remote status pushes use the cross-vendor VALUES() form until #590 supplies an independently detected main-server capability. Behavior worth calling out: - colon/dash-delimited hexadecimal values that were previously stored as zero now convert correctly - values wider than 64 bits become U and count as collection errors instead of producing undefined numeric conversion - remote batches flush before the boundary-triggering row and refuse truncated statements Verification on macOS arm64: - warning-enabled C99 configure/build - forced make -B check on the final tree: 6 pass, 1 expected skip - the skipped allocation-failure integration uses Linux LD_PRELOAD and runs in Linux CI - full VPATH make distcheck passed earlier in this branch - mandatory independent pre-push review: PASS Closes #564 Closes #565 Closes #566 Closes #567 Closes #588 Refs #590 Refs #597 --------- Signed-off-by: Thomas Vincent <thomasvincent@gmail.com> Signed-off-by: TheWitness <copilot@users.noreply.github.com> Co-authored-by: TheWitness <copilot@users.noreply.github.com> Co-authored-by: TheWitness <thewitness@cacti.net> |
