File src/hlr.c:

https://gerrit.osmocom.org/#/c/12526/4/src/hlr.c@442
PS4, Line 442:          LOGP(DMAIN, LOGL_INFO, "%s: has IMEI: %s (consider 
setting 'store-imei 1')\n", gsup->imsi, imei);
if the subscriber doesn't exist, we should respond with an error.
I'm not saying to implement an IMEI black/whitelist, but at least to error if 
the IMSI isn't known at all.
i.e. always first db_subscr_get_by_imsi().

I'm not sure if we need to optimize for db performance, but if we do, then this 
would be an obvious improvement:
To have less DB hits instead implement db_update_imei_by_imsi(), so that we 
check IMSI presence and update the IMEI in one DB hit. A returned value of zero 
modified rows would then mean "IMSI not known".

File src/hlr_vty.c:

https://gerrit.osmocom.org/#/c/12526/4/src/hlr_vty.c@75
PS4, Line 75:           vty_out(vty, "  store-imei 1%s", VTY_NEWLINE);
looks like too much indent.
Add a vty test for this to one or other .vty transcript test, please (check 
output of 'show running-config')


https://gerrit.osmocom.org/#/c/12526/4/src/hlr_vty.c@313
PS4, Line 313:  " to set 'check-imei-rqd 1' in osmo-msc.cfg.\n"
wording: maybe rather "Note that an MSC does not necessarily send Check IMEI 
requests (for OsmoMSC, you may want to set 'check-imei-rqd 1')."

consistency: AFAICT osmo-hlr so far uses only the 'foo' / 'no foo' syntax, so 
better also make this

   'store-imei'
   'no store-imei'

(
If you decide to keep (0|1), then the first doc should be general for switching 
it off or on:

  store-imei  Configure whether to store a received IMEI in the database.

    0   Do not store...
    1   Store received IMEIs. Note that an MSC does not necessarily send Check 
IMEI
        requests (for OsmoMSC, you may want to set 'check-imei-rqd 1').
)
