Patch Set 9: (2 comments) File include/osmocom/hnbgw/hnbgw.h: https://gerrit.osmocom.org/c/osmo-hnbgw/+/32323/comment/2e47297f_08df39f5 PS8, Line 87: DECLARE_HASHTABLE(hnbgw_context_map_by_conn_id, 6); it would be pretty much exactly the name of the table: /* hash table of struct hnbgw_context_map by SCCP conn ID */ but ok if it helps i can do it https://gerrit.osmocom.org/c/osmo-hnbgw/+/32323/comment/8c1542b3_125575af PS8, Line 133: if (!cnlink->hnbgw_sccp_user) In places where it's established to be safe i can just use cnlink->hnbgw_sccp_usser->ss7->sccp directly. This function's reason to exist is to avoid NULL dereferences. I want to call this function in *any* godforsaken corner case from early init to late cleanup, and never run into a NULL deref. I want to get the osmo_sccp_instance, or NULL if there isn't any, for whichever weird reason there might be. In the branch's final state, this function is called in two places: cnlink_sccp_addr_to_str(): return a string for logging -- if it is early link startup logging there might be no SCCP instance, or anything leading up to the SCCP instance, assigned yet. tx_reset_ack(): the SCCP link should be stable, but we're in the middle of a RESET operation, so it could be some state transition, and rarely happens. I decided to just do the extra check. I thought I'd need it more often, but two places is already enough to not dup all these checks. -- To view, visit https://gerrit.osmocom.org/c/osmo-hnbgw/+/32323 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-hnbgw Gerrit-Branch: master Gerrit-Change-Id: Iea1824f1c586723d989c80a909bae16bd2866e08 Gerrit-Change-Number: 32323 Gerrit-PatchSet: 9 Gerrit-Owner: neels <nhofmeyr(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: laforge <laforge(a)osmocom.org> Gerrit-Reviewer: pespin <pespin(a)sysmocom.de> Gerrit-CC: msuraev <msuraev(a)sysmocom.de> Gerrit-Attention: pespin <pespin(a)sysmocom.de> Gerrit-Attention: msuraev <msuraev(a)sysmocom.de> Gerrit-Comment-Date: Wed, 31 May 2023 23:49:09 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: pespin <pespin(a)sysmocom.de> Gerrit-MessageType: comment
