yep that makes sense

ah reading their analysis, there are errors that explain this. Particularly this:

  tcp_now   = 4,294,960,000  (frozen at pre-overflow value)
  timer     = 4,294,960,000 + 30,000 = 4,294,990,000
              (exceeds uint32 max → wraps to a small number)

timer wraps to a small number, they say

  TSTMP_GEQ(4294960000, 4294990000)

they forgot to wrap it there, it should be TSTMP_GEQ(4294960000, small_number)

  = (int)(4294960000 - 4294990000)
  = (int)(-30000)
  = -30000 >= 0 ?  → false!

wrong!

There may be a short time period where this bug occurs, and if you get enough TCP connections to TIME_WAIT in that period, they could stick around, maybe. But I think the original post is completely overreacting and was probably written by a LLM, lol.

have multiple macOS machines with 600-1000+ day uptimes, which do TCP connections every minute or so at a minimum, they are still expiring their TIME_WAIT connections as normal.

these kernel versions:

so... wonder what that's about?

+1 here -- Mutsu are fantastic, readily available at NYC greenmarkets in the fall and into the winter, though there are pretty large differences in flavor and texture between various orchards too. Samascot is my fav.

If you have an Apple Silicon mac you can install Win11 in UTM and it works great for dev purposes. Can get the free builds via Windows Insider, too.

except: 1) avoid the possibility of head injuries, and 2) if you suffer more than slight symptoms from daily routine, dial it back

or you might have an alternate prefix for "things that go in development build changelogs but not final changelogs", e.g. "-"
