Patch Set 4: Code-Review+1 (5 comments) Patchset: PS4: Ok, I see, and agree with this. Below some petty details below. First petty detail: we could squash it into that other patch. File src/libosmo-mgcp/mgcp_network.c: https://gerrit.osmocom.org/c/osmo-mgw/+/35176/comment/e0c4ce52_25437aa2 PS4, Line 838: osmo_sockaddr_port(&conn->end.addr.u.sa) == 0) { the most concise restriction would be: - validate the IP address if present, - and validate the port if present, independently. I mean, in this patch we skip both checks if one of them is not set. Instead we can skip only the port number check if port == 0, and skip only the address check if address == ANY. (That's mainly why it's so compelling to just skip sender validation for early IuUP entirely; doing checks properly rejiggers this entire function.) https://gerrit.osmocom.org/c/osmo-mgw/+/35176/comment/6ec9f8d2_73ec40b1 PS4, Line 841: announce "not all hNodeB", but some are happily sending RAB Assignment success before IuUP Initialization. I find "MGCP client" confusing here, the hNodeB obviously does not talk MGCP protocol. https://gerrit.osmocom.org/c/osmo-mgw/+/35176/comment/a34c5956_389c6fc8 PS4, Line 842: ASs (RAB Assignment Response at HNBGW) https://gerrit.osmocom.org/c/osmo-mgw/+/35176/comment/f783b56a_3eb116ae PS4, Line 843: MDCX Writing "MDCX" is too specific: it is up to the client to do CRCX with SDP all-in-one or adjust with MDCX later. I'd rather write: Hence the MGW may not yet know the remote IuUP address and port at the time of receiving IuUP Initialization from the hNodeB. -- To view, visit https://gerrit.osmocom.org/c/osmo-mgw/+/35176?usp=email To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-mgw Gerrit-Branch: master Gerrit-Change-Id: Idd833997abce46886e9664505b2776fa5dadc8db Gerrit-Change-Number: 35176 Gerrit-PatchSet: 4 Gerrit-Owner: pespin <pespin(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: neels <nhofmeyr(a)sysmocom.de> Gerrit-Attention: pespin <pespin(a)sysmocom.de> Gerrit-Comment-Date: Mon, 04 Dec 2023 23:41:07 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: Yes Gerrit-MessageType: comment
