enum osmo_auth_algo features OSMO_AUTH_ALG_XOR, but now that I'm trying to use it, I notice that we have no code actually implementing OSMO_AUTH_ALG_XOR.
We have xor as algorithm exposed as a VTY option in the osmo-hlr DB, but when I choose it, I must notice that libosmocore doesn't osmo_auth_register() any xor implementation.
Another detail is that I happen to remember that XOR is set as algorithm on the SIM cards we have in the osmo-gsm-tester, at least in the RnD unit.
How should we deal with it? Implement xor, or remove it from osmo-hlr? Or am I missing something?

why is that? This would have been done explicitly as none of our cards had it by default.

I'd suggest * hide XOR as a selectable option in OsmoHLR for now * create Low-prio feature ticket for libosmocore o implement XOR support, and at that time enable it in OsmoMSC + OsmoHLR.
There's this related ticket in osmo-gsm-tester that was created a while ago: "Set up SIM cards with auth algo other than XOR" https://osmocom.org/issues/2497
