Quentin McGaw 3c84a94f11 hotfix(pmtud/ip): handle network is unreachable silently 2026-05-07 19:20:50 +00:00
Quentin McGaw 4a78989d9d chore: do not use sentinel errors when unneeded
- main reason being it's a burden to always define sentinel errors at global scope, wrap them with `%w` instead of using a string directly
- only use sentinel errors when it has to be checked using `errors.Is`
- replace all usage of these sentinel errors in `fmt.Errorf` with direct strings that were in the sentinel error
- exclude the sentinel error definition requirement from .golangci.yml
- update unit tests to use ContainersError instead of ErrorIs so it stays as a "not a change detector test" without requiring a sentinel error

Quentin McGaw 8d86470905 feat(pmtud/tcp): use the TCP server with highest MSS to run MTU tests 2026-02-19 14:03:46 +00:00
Quentin McGaw 5f903d1fbf chore(pmtud): remove calls to syscall in favor of unix and windows
- syscall is deprecated and is not kept up-to-date
- each OS is inherently different hence the syscall being deprecated

Quentin McGaw be92aa2ac4 Path MTU discovery fixes and improvements (#3109)
- Existing option `WIREGUARD_MTU` , if set, disables PMTUD and is used
- New option `PMTUD_ICMP_ADDRESSES=1.1.1.1,8.8.8.8` and `PMTUD_TCP_ADDRESSES=1.1.1.1:443,8.8.8.8:443`
- ICMP PMTUD now targets external-by-default IP addresses
- New TCP PMTUD (binary search only) as a second MTU confirmation and fallback mechanism.
- Force set TCP MSS to MTU - IP header - TCP base header - "magic 20 bytes" 🎆
- Fix #3108
