Open mdlayher opened 7 years ago

mdlayher commented 7 years ago

Add the connectionless counterparts alongside the existing connection-oriented API.

Hey @stefanha, have the datagram sockets been implemented yet? Last I was aware, I don't think they were available.

SOCK_DGRAM is not available yet. There is currently no work in this area.

There may be some work on this now: https://lwn.net/Articles/859271/.

SOCK_SEQPACKET and SOCK_DGRAM are on the way but not 100% finished yet. @stefano-garzarella

Yep, SOCK_SEQPACKET is almost done. It is also merged in virtio-spec 1.2 and supported starting from Linux v5.14 and QEMU v6.1.

For SOCK_DGRAM, Jiang is still working on it. It hasn't landed upstream yet.

Thank you both for the updates!

Hey @stefano-garzarella, is there any update on this? AFAICT, there was some LKML activity back in June 2023 and I assume the patch set hasn't landed yet? Thanks!

Yep, the patches are not landed yet. AFAIK @beshleman and his colleagues in ByteDance are working on that.

beshleman commented 10 months ago

This is true. We should see new spec/code patches out very soon (this or next month I think).

Excellent news! Happy to incorporate dgram mode as appropriate once the kernel APIs are ready to go.
