[M] Change in osmo-msc[master]: add vty setting for ThemWi RTP formats
by falconia 19 Dec '25

19 Dec '25

Attention is currently required from: fixeria, laforge, pespin. Hello Jenkins Builder, fixeria, laforge, pespin, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-msc/+/41698?usp=email to look at the new patch set (#7). The following approvals got outdated and were removed: Code-Review+1 by fixeria, Code-Review+1 by laforge, Code-Review+2 by pespin, Verified+1 by Jenkins Builder The change is no longer submittable: Code-Review and Verified are unsatisfied now. Change subject: add vty setting for ThemWi RTP formats ...................................................................... add vty setting for ThemWi RTP formats For every GSM speech codec and for CSD, Osmocom BSS supports both the standard RTP format prescribed by 3GPP and an alternative enhanced RTP format invented by Themyscira Wireless: TW-TS-001, TW-TS-002, TW-TS-006 and TW-TS-007. In order to enable these enhanced RTP formats, the MSC needs to include an extension IE in the Assignment Request it sends to the BSS. Until now there was no way to do so in mainline OsmoMSC, only via local code patches - fix this omission. The following considerations apply to this new tw-rtp-formats vty setting: * When internal MNCC is used, it is beneficial to enable enhanced TW RTP formats, especially when using E1 BTS with tw-e1abis-mgw: the DL call leg receives more complete information content from the UL call leg in each direction. * When external MNCC is used with non-ThemWi CN software (e.g., with a PBX via osmo-sip-connector), tw-rtp-formats should NOT be enabled - off-the-shelf PBX etc software won't understand them. * Future patches will allow osmo-msc to operate with a ThemWi transcoding MGW (TC to G.711) in the place of non-TC osmo-mgw; in that configuration TW RTP formats will become mandatory, as they are strictly required by ThemWi TC implementation.

[S] Change in libosmocore[master]: gsmtap_util: Increase source_fd's SO_SNDBUF to 4MB
by pespin 18 Dec '25

18 Dec '25

pespin has submitted this change. ( https://gerrit.osmocom.org/c/libosmocore/+/41716?usp=email ) Change subject: gsmtap_util: Increase source_fd's SO_SNDBUF to 4MB ...................................................................... gsmtap_util: Increase source_fd's SO_SNDBUF to 4MB Using bpftrace we spotted osmo-bts sporadically blocking on send() of gsmtap_log for 2-4s, most probably due to the UDP send buffer being full. The wmem_default of ~292KB is indeed a bit tight, and for instance upstream Linux got its wmem_max to 4MB in april 2025 since it's becoming more usual that sockets need to increase this value. Hence, increase the SO_SNDBUF to 4MB to get some extra room and avoid blocks (or drops if socket is later on set non-blocking) and be able to accomodate to logging spikes better. The kernel will take care of lowering the size set to the configured net.core.wmem_max if needed.
