Patch Set 2: (1 comment) File src/osmo-bsc-nat/bssap_conn.c: https://gerrit.osmocom.org/c/osmo-bsc-nat/+/28582/comment/0cfff071_f23be8f0 PS2, Line 60: len = IP_V4_ADDR_LEN; AFAIR and from waht you mention, msgb_put checks length by calling osmo_panic(), which is not desirable. That osmo_panic is just to signal that something is really wrong in the caller code. So we want proper checking here, not just osmo_panic. I still think the proper way is to handle one check inside gsm0808_enc_aoip_trasp_addr() and another one directly in this function for the path calling tlv_encode_one(). Because for the first path, you always want to have that checked, and I'd expect that function to check that. For the other path, you are really doing different stuff and it's fine doing the check in the same function. -- To view, visit https://gerrit.osmocom.org/c/osmo-bsc-nat/+/28582 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-bsc-nat Gerrit-Branch: master Gerrit-Change-Id: I1fc4c81e139bab3d7d977ef9467f62d8088884db Gerrit-Change-Number: 28582 Gerrit-PatchSet: 2 Gerrit-Owner: osmith <osmith(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: pespin <pespin(a)sysmocom.de> Gerrit-Attention: osmith <osmith(a)sysmocom.de> Gerrit-Comment-Date: Wed, 13 Jul 2022 12:25:42 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: osmith <osmith(a)sysmocom.de> Comment-In-Reply-To: pespin <pespin(a)sysmocom.de> Gerrit-MessageType: comment
