Treat rule_set items as merged branches instead of standalone boolean
sub-items.
Evaluate each branch inside a referenced rule-set as if it were merged
into the outer rule and keep OR semantics between branches. This lets
outer grouped fields satisfy matching groups inside a branch without
introducing a standalone outer fallback or cross-branch state union.
Keep inherited grouped state outside inverted default and logical
branches. Negated rule-set branches now evaluate !(...) against their
own conditions and only reapply the outer grouped match after negation
succeeds, so configs like outer-group && !inner-condition continue to
work.
Add regression tests for same-group merged matches, cross-group and
extra-AND failures, DNS merged-branch behaviour, and inverted merged
branches. Update the route and DNS rule docs to clarify that rule-set
branches merge into the outer rule while keeping OR semantics between
branches.
Before 795d1c289, nested rule-set evaluation reused the parent rule
match cache. In practice, this meant these fields leaked across nested
evaluation:
- SourceAddressMatch
- SourcePortMatch
- DestinationAddressMatch
- DestinationPortMatch
- DidMatch
That leak had two opposite effects.
First, it made included rule-sets partially behave like the docs'
"merged" semantics. For example, if an outer route rule had:
rule_set = ["geosite-additional-!cn"]
ip_cidr = 104.26.10.0/24
and the inline rule-set matched `domain_suffix = speedtest.net`, the
inner match could set `DestinationAddressMatch = true` and the outer
rule would then pass its destination-address group check. This is why
some `rule_set + ip_cidr` combinations used to work.
But the same leak also polluted sibling rules and sibling rule-sets.
A branch could partially match one group, then fail later, and still
leave that group cache set for the next branch. This broke cases such
as gh-3485: with `rule_set = [test1, test2]`, `test1` could touch
destination-address cache before an AdGuard `@@` exclusion made the
whole branch fail, and `test2` would then run against dirty state.
795d1c289 fixed that by cloning metadata for nested rule-set/rule
evaluation and resetting the rule match cache for each branch. That
stopped sibling pollution, but it also removed the only mechanism by
which a successful nested branch could affect the parent rule's grouped
matching state.
As a result, nested rule-sets became pure boolean sub-items against the
outer rule. The previous example stopped working: the inner
`domain_suffix = speedtest.net` still matched, but the outer rule no
longer observed any destination-address-group success, so it fell
through to `final`.
This change makes the semantics explicit instead of relying on cache
side effects:
- `rule_set: ["a", "b"]` is OR
- rules inside one rule-set are OR
- each nested branch is evaluated in isolation
- failed branches contribute no grouped match state
- a successful branch contributes its grouped match state back to the
parent rule
- grouped state from different rule-sets must not be combined together
to satisfy one outer rule
In other words, rule-sets now behave as "OR branches whose successful
group matches merge into the outer rule", which matches the documented
intent without reintroducing cross-branch cache leakage.
PreMatch and full match phases each created a fresh InboundContext,
causing process search (expensive OS syscalls) to run twice per
connection. Use a freelru ShardedLRU cache with 200ms TTL to serve
the second lookup from cache.
Add fpm-based Alpine APK packaging alongside existing DEB/RPM/Pacman
packages. Alpine APKs use `linux` in the filename to distinguish from
OpenWrt APKs which use the `openwrt` prefix.
