nbjoerghm. I still have that 6 year old zero broadcast patch around
-
nbjoergI wonder if I should push that one again...
-
nbjoergnetbsd.org/~joerg/no-zero-broadcast.diff <-- remove a relict from the ancient past
-
danmcdnbjoerg: SOmething like this it's always about comprehensive testing.
-
nbjoergack
-
nbjoergthis is essentially removing a workaround for a 4.3BSD network "feature"
-
nbjoergI think illumos is one of the few systems still left with this restriction...
-
danmcdI know all about all-0s (And it goes back to 4.2 if not earlier).
-
nbjoergI forgot why I hit this in 2016 and looked at it
-
danmcdI'm also curious if removing this *just might* allow /31 w/o further alterations?
-
nbjoergyou might need to still skip the regular broadcast in that case?
-
danmcdAs of this moment, my /31 thoughts were to push it up into userspace, and then configure IFF_POINTOPOINT under the covers (which is how you actually deploy a /31 IPv4 on illumos today).
-
danmcdDoh, yes. Sorry, just got up.
-
danmcd(My thoughts then still stand.)
-
nbjoergthat said, it should highlight most of the relevant cases to touch
-
nbjoergis /31 still used?
