Quentin McGaw	bc79901f1e	chore(pmtud/tcp): restrict temp firewall rules to source ip and source port	2026-02-19 13:20:58 +00:00
Quentin McGaw	04d7cef294	hotfix(pmtud/tcp): block kernel from racing to send RST packets ... - this makes PMTUD TCP reliable - this only works on kernels with the mark module - on kernels without the mark module, the icmp pmtud mtu found is used	2026-02-17 21:46:24 +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	2026-02-17 21:46:04 +00:00
Quentin McGaw	f81b8342d6	hotfix(pmtud/tcp): temporary test fix	2026-02-16 23:54:38 +00:00
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	2026-02-14 19:40:34 -05:00
