commit b00d30950cde27eda8f51523a40f2c05a38daac1 Author: Pouria Mousavizadeh Tehrani <[email protected]> AuthorDate: 2026-07-17 16:11:42 +0000 Commit: Pouria Mousavizadeh Tehrani <[email protected]> CommitDate: 2026-07-20 17:27:15 +0000 net/if.c: Add fib-aware ifa_ifwithaddr() Add FIB selection logic by introducing ifa_ifwithaddr_fib() to support FIB-specific lookups. Then have ifa_ifwithaddr() wrap it with RT_ALL_FIBS. Also, do the same for ifa_ifwithaddr_check().
