https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D252596 --- Comment #7 from Inoki <veyx.shaw@gmail.com> --- (In reply to Mike Karels from comment #5) Yes, I saw the option in the kernel code, there is. But as far as I can see, none of the applications/frameworks seems to have set the flag explicitly (= at least the ping, and the Qt stuff). They worked before because in_broadcast() does check the INET_BROADCAST address. But the mentioned commit changes the callee to in_ifaddr_broadcast(), which does not contain such processing anymore. I checked the FreeBSD part in the XNU (macOS kernel), which is an old relea= se. The ping and our UDP broadcast keeps working on macOS. But they are broken = on current FreeBSD kernel.=20 For the compatibility, should the flag be fixed in the kernel instead of explicitly being set by the application, when the address is set to 255.255.255.255 (all ones)? --=20 You are receiving this mail because: You are the assignee for the bug.=
