The branch main has been updated by emaste: URL: https://cgit.FreeBSD.org/src/commit/?id=b8c1aadef9d80786daf731300c33d3a001261422 commit b8c1aadef9d80786daf731300c33d3a001261422 Author: Olivier Certner <olce.freebsd@certner.fr> AuthorDate: 2023-05-25 11:48:40 +0000 Commit: Ed Maste <emaste@FreeBSD.org> CommitDate: 2023-10-02 20:41:22 +0000 login_cap.c: Don't set errno to ERANGE on memory allocation failure Modified functions: login_getcaptime(), login_getcapnum(), login_getcapsize(). They all call cgetstr(), which returns -2 on such conditions and already sets errno to ENOMEM, arguably the appropriate value for these functions as well. No in-tree consumer currently checks for errno on error reported by these functions, so this change has no other code impact.
