Patch Set 6: (1 comment) File src/core/gsmtap_util.c: https://gerrit.osmocom.org/c/libosmocore/+/34743/comment/60b927bc_93d7e161 PS5, Line 478: osmo_iofd_setup(gti, gti->sink_fd, "gsmtap_inst.out", OSMO_IO_FD_MODE_READ_WRITE, &gsmtap_sink_ops, NULL); Yeah, one option is to keep it like it was not using osmo_io (so that the read doesn't allocate). I was wondering what happens if you open the socket and simply never read from it since we don't care about the data anyway. I don't think it's worth the effort here because we might need to decrease the kernel receive buffer and even then the kernel could send ICMP errors. So I'd suggest to keep the source_add_sink code as it was before (using osmo_fd with the read callback). -- To view, visit https://gerrit.osmocom.org/c/libosmocore/+/34743?usp=email To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: libosmocore Gerrit-Branch: master Gerrit-Change-Id: Iadbbef74e3add7001d84dd6b68f51eac293e44d0 Gerrit-Change-Number: 34743 Gerrit-PatchSet: 6 Gerrit-Owner: arehbein <arehbein(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: daniel <dwillmann(a)sysmocom.de> Gerrit-Reviewer: pespin <pespin(a)sysmocom.de> Gerrit-CC: laforge <laforge(a)osmocom.org> Gerrit-Attention: arehbein <arehbein(a)sysmocom.de> Gerrit-Attention: laforge <laforge(a)osmocom.org> Gerrit-Attention: pespin <pespin(a)sysmocom.de> Gerrit-Comment-Date: Tue, 24 Oct 2023 08:50:22 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: arehbein <arehbein(a)sysmocom.de> Comment-In-Reply-To: daniel <dwillmann(a)sysmocom.de> Gerrit-MessageType: comment
