2022-04-12Avoid generating zero-length packetsHarald Welte1-3/+3
I used the construct like f_rnd_octstring(f_rnd_int(100)) in a number of places to generate random-length packets with randomized length. The problem I didn't realize is that f_rnd_int() of course can also return '0', which would generate zero-length packets. This may be permitted in some protocols, but it leads to problems e.g. when trying to send a UDP packet of zero length (which the kernel will not do). So let's introduce * f_rnd_int_nonzero() for returning non-zero randomized integers * f_rnd_octstring_rnd_len() for returning a random-length random payload octet string * replace all f_rnd_octstring(f_rnd_int()) call sites with the new function.

2021-10-26sccp: Add TC_process_rx_xudt, verifying reception of SCCP XUDTHarald Welte1-0/+26
Test if a XUDT SCCP message is processed by libosmo-sigtran. We assume any XUDT is received (and echoed back) just like normal UDT. Related: OS#5281, SYS#5674 Change-Id: Idbf6db7a684e51858129618b2fcffcbe55b1b70f
2021-05-13sccp: Add TC_callingparty_ssn_only()Harald Welte1-1/+23
This test verifies that libosmo-sccp will properly respond to SCCP traffic that only has a SSN in the CallingPartyAddress. That situation poses the unique challenge of how to route a response, as we lack a GT and a PC to do the routing. In order to support this, libosm-sccp now adds the PC into the CallingPartyAddr when passing such messages from M3UA to SCCP. This way the recipient can simply respond back to that address and it will be routed on PC. Change-Id: Ided599a922fb7f6dbbfe90f817c5419ab793f293 Related: OS#5146
2021-02-11sccp: Add Tests for SCMG SST procedureHarald Welte1-0/+98
The SST procedure can be used by any SCCP node to test the availability of a remote SSN. If the specified remote SSN is available at the specified PC, a SCMG SSA is returned. If not, there's a timeout. Test for SSN=1 (SCMG), another non-SCMG SSN that exists, and for one SSN that doesn't exist. Change-Id: If3f5f3144c0ed83d0bda5953522a9d73287c8ba2

2020-01-21sccp: Don't use hardcoded SCCP local referencesPau Espin Pedrol1-10/+23
as tests are added or order is changed, local references used by the system under test may change, so let's take and use the one notified instead of harcoding values. Change-Id: I2b52cc637c20d5644f413030edd9040a6e6bfe2f
