[M] Change in libosmocore[master]: gsmtap_util: Use Osmo IO instead of Osmo write queues

by daniel

Attention is currently required from: arehbein, laforge, pespin. daniel has posted comments on this change. ( https://gerrit.osmocom.org/c/libosmocore/+/34743?usp=email ) Change subject: gsmtap_util: Use Osmo IO instead of Osmo write queues ...................................................................... Patch Set 8: (1 comment) File src/core/gsmtap_util.c: https://gerrit.osmocom.org/c/libosmocore/+/34743/comment/8a07c099_d0014ba2 PS5, Line 478: osmo_iofd_setup(gti, gti->sink_fd, "gsmtap_inst.out", OSMO_IO_FD_MODE_READ_WRITE, &gsmtap_sink_ops, NULL); > In that case I guess we want to limit somehow the read buffer queue in the kernel to the minimum (even 0) to avoid wasting kb/mb of memory for each gsmtap socket sink with filled message that are never read. Yeah, might be a good idea, but out of scope for this patch. @arehbein@sysmocom.de gsmtap_source_add_sink is called in logging_gsmtap.c and also in osmo_pcu and osmo_bts. In libosmocore/src/vty/logging_vty.c cfg_log_gsmtap calls log_target_create_gsmtap with false, true as last parameters. That means ofd_wq_mode false and add_sink true. We should change the ofd_wq_mode parameter to true here, otherwise it doesn't use osmo_io at all. Not sure if we need a VTY parameter for that. Since add_sink is true the code will call gsmtap_source_add_sink() which creates the sink only if the gsmtap target is local. So simply enabling gsmtap logging to 127.0.0.1 should call the code in question. -- 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: 8 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 12:05:02 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: arehbein <arehbein(a)sysmocom.de> Comment-In-Reply-To: laforge <laforge(a)osmocom.org> Comment-In-Reply-To: pespin <pespin(a)sysmocom.de> Comment-In-Reply-To: daniel <dwillmann(a)sysmocom.de> Gerrit-MessageType: comment

[M] Change in libgtpnl[master]: Add IPv6 support

by osmith

Attention is currently required from: fixeria, laforge, osmith, pespin. Hello Jenkins Builder, fixeria, laforge, pespin, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/libgtpnl/+/34735?usp=email to look at the new patch set (#5). The following approvals got outdated and were removed: Verified+1 by Jenkins Builder, Verified+1 by osmith Change subject: Add IPv6 support ...................................................................... Add IPv6 support Implement IPv6 in libgtpnl and the gtp-tunnel testing tool. Allow to combine: - GTPA_MS_ADDRESS and GTPA_PEER_ADDR6 - GTPA_MS_ADDR6 and GTPA_PEER_ADDRESS to specify IPv4-in-IPv6-GTP and IPv6-in-IPv4-GTP in the tunnel declaration from control plane. This patch is based on multiple patches from Pablo in OS#6123. I decided to squash them to directly implement v4-in-v6 and vice versa, instead of implementing another variant first and then changing it again.
