The old interface still exists for UDP but will be removed when I am less lazy. From testing it does not appear to have any performance improvement but this is most likely due to other bottlenecks as extra copies should always be worse. Kernel/Net: Don't use kmalloc to create send buffers 2024-07-08T19:37:15+00:00 Anton Kling anton@kling.gg 2024-07-08T19:37:15+00:00 urn:sha1:e49d2a9fa5a485c33a250ce843d44fc6dedea8b5 Current method is also really bad since it uses multiple copies when it should instead just copy to the send buffer of the network card directly. But I have other things that I want to prioritize first.

Applications that don't wish to use this should disable this for their socket. Bug fix: Fix undefined behavior of ipv4_t type. 2024-06-28T15:57:45+00:00 Anton Kling anton@kling.gg 2024-06-28T15:56:53+00:00 urn:sha1:b747eb399c556858e05de51b1bb3e875c834c8e0 Turns out unions that include arrays and a integer can have UB due to endianess not being the same across systems.
