Patch Set 1: (1 comment) File src/libosmo-mgcp-client/mgcp_client.c: https://gerrit.osmocom.org/c/osmo-mgw/+/35322/comment/4c625f74_e0fabcf7 PS1, Line 762: ret = read(fd->fd, msg->data, msgb_tailroom(msg) - 1); JFYI, the nul-termination is already done deeper in the code: ``` mgcp_do_read() // this func mgcp_client_rx() mgcp_response_parse_head() mgcp_msg_terminate_nul() ``` I am simply making sure that there will be enough room for this function to terminate the received string, if needed. What you suggest is also an option, indeed, except that `msg->l2h[OSMO_MIN(ret, msgb_l2len(msg))]` does not make sense to me because the code is doing `msg->l2h = msgb_put(msg, ret)` below, so that `ret == msgb_l2len(msg)`. Let's see what the others think. -- To view, visit https://gerrit.osmocom.org/c/osmo-mgw/+/35322?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: Icc878af7f671213bb516af62cb601914d86ff808 Gerrit-Change-Number: 35322 Gerrit-PatchSet: 1 Gerrit-Owner: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-CC: pespin <pespin(a)sysmocom.de> Gerrit-Attention: pespin <pespin(a)sysmocom.de> Gerrit-Comment-Date: Mon, 11 Dec 2023 14:49:52 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: pespin <pespin(a)sysmocom.de> Gerrit-MessageType: comment
