Hello Jenkins Builder,
I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/c/libosmo-sccp/+/34264
to look at the new patch set (#2).
Change subject: ipa: use LSBs of file descriptor as SLS in IPA->M3UA direction
......................................................................
ipa: use LSBs of file descriptor as SLS in IPA->M3UA direction
when IPA/SCCPlite traffic traverses the osmo_ss7 stack, so far the
SLS of the MTP3 label was always set to 0 (default initialization).
However, in order to achieve a better distribution of signaling traffic
in SS7 networks that actually utilize the SLS to select any links (or
ASPs), it makes sense to use non-zero values.
Instead of introducing some kind of new, configurable attribute for
each ASP (IPA client connection), let's simply use the lower 4 bits of
the file descriptor integer. Those file descriptors should have a
roughly equal distribution, resulting in traffic (from multiple IPA
clients) to be spread across the 4-bit SLS number space.
Also, this mechanism ensures that traffic from one IPA client will
always get the same SLS and hence routed the same way in any underlying
CS7/SS7 network.
