https://bugzilla.kernel.org/show_bug.cgi?id=19812 Summary: two issues in unix(7) Product: Documentation Version: unspecified Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: man-pages AssignedTo: documentation_man-pages@xxxxxxxxxxxxxxxxxxxx ReportedBy: mzxreary@xxxxxxxxxxx Regression: No There are two smaller issues in the unix(7) man page: 1) The part about "pathname" sockets suggests usage of sizeof(sa_family_t) + strlen(sun_path) + 1 for calculating the sockaddr size. Due to alignment/padding this is probably not a good idea. Instead, one should use offsetof(struct sockaddr_un, sun_path) + strlen() + 1 or something like that. 2) The part about "abstract" sockets is misleading as it suggests that the sockaddr returned by getsockname() would necessarily have the size of sizeof(struct sockaddr), which however is not the case: getsockname() returns exactly the sockaddr size that was passed in on bind(). In particular, two sockets that are bound to the same sockaddr but different sizes are completely independant. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-man" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
