As it can be seen, the default prio (0) when no prio is selected is the highest one. Now comes the question whether this is desired, or we should be setting prio 0xffffff by default (the lower one), or some intermediate value like 0xff00000. This would also mean changing old behavior, but in this case we know for sure the priority stuff was not being used at all anywhere so it shouldn't be a problem. -- To view, visit https://gerrit.osmocom.org/c/libosmo-sigtran/+/38375?usp=email To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings?usp=email Gerrit-MessageType: comment Gerrit-Project: libosmo-sigtran Gerrit-Branch: master Gerrit-Change-Id: I6e7b5e3f06ae2c9468da58c55d2f42cbcd777218 Gerrit-Change-Number: 38375 Gerrit-PatchSet: 2 Gerrit-Owner: pespin <pespin(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Comment-Date: Wed, 09 Oct 2024 18:14:02 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No

[L] Change in libosmo-sigtran[master]: ss7 vty: Fix insert order of routes with higher priority

by pespin

Attention is currently required from: pespin. Hello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/libosmo-sigtran/+/38375?usp=email to look at the new patch set (#2). The following approvals got outdated and were removed: Verified-1 by Jenkins Builder Change subject: ss7 vty: Fix insert order of routes with higher priority ...................................................................... ss7 vty: Fix insert order of routes with higher priority Route lookup ((hmrt_message_for_routing() => osmo_ss7_route_lookup() => osmo_ss7_route_find_dpc_mask())) iterates the list of routes assuming they are ordered by mask length (so it doesn't need to iterate the full list every time). Similary, it implicitly seems to assume that the entries are also sorted by priority. However, priority is not currently taken into account when being inserted in the routing table, so the route ends up in the incorrect place. The VTY "update route" command used to first insert the route and only *after* that tweak some of its fields, like priority or qos-class. This commit adds a new set of osmo_ss7_route API which allows users to *first* allocate a route and configure it completelly, and *second* insert it once it contains all the information. This way, the insert algorithm can take into account the configured route priority and place the route entry in the routing table at the proper place.

[M] Change in libosmo-sigtran[master]: tests/vty: Show bug inserting routes with different priority

by pespin

Hello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/libosmo-sigtran/+/38374?usp=email to look at the new patch set (#2). The following approvals got outdated and were removed: Verified+1 by Jenkins Builder Change subject: tests/vty: Show bug inserting routes with different priority ...................................................................... tests/vty: Show bug inserting routes with different priority route lookup ((hmrt_message_for_routing() => osmo_ss7_route_lookup() => osmo_ss7_route_find_dpc_mask())) iterates the list of routes assuming they are ordered by mask length (so it doesn't need to iterate the full list every time). Similary, it implicitly seems to assume that the entries are also sorted by priority. However, priority is not currently taken into account when being inserted in the routing table, so the route ends up in the incorrect place. This commit adds a VTY test showing the wrong insert.
