Christof Meerwald 0ab42081b5 kernel/network: Limit send MSS by interface MTU
see RFC9293 3.7.1. Maximum Segment Size Option

  The maximum size of a segment that a TCP endpoint really sends, the
  "effective send MSS", MUST be the smaller of the send MSS (that
  reflects the available reassembly buffer size at the remote host)
  and the largest transmission size permitted by the IP layer.

Previously, instead of just choosing a lower send MSS, we would
(try to) fragment those packets.

With this change I now get a 10/10 score from test-ipv6.com when
setting the local MTU to 1280 (this is needed as a workaround as we
don't implement Path MTU Discovery).

Haiku

Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs

Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.

Goals

  • Sensible defaults with minimal configuration required.
  • Clean, clear, concise code.
  • Unified desktop environment.

Trying Haiku

Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.

Compiling Haiku

See ReadMe.Compiling.
