Some getaddrinfo implementations do not detect invalid numeric services and blindly pass the port number to htons(). For example, service "960179" is returned as port 42675. glibc https://sourceware.org/bugzilla/show_bug.cgi?id=16208 https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/posix/getaddrinfo.c;h=a8bdd9a1829409bd797637b2c4fca4d67a11012d;hb=HEAD#l435 https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/posix/getaddrinfo.c;h=a8bdd9a1829409bd797637b2c4fca4d67a11012d;hb=HEAD#l2313 AIX 7.1 libc Broken Modules/getaddrinfo https://github.com/python/cpython/blob/master/Modules/getaddrinfo.c#L342 On the other hand, for example, OpenBSD and musl check the port range https://github.com/openbsd/src/blob/master/lib/libc/asr/getaddrinfo_async.c#L477 https://git.musl-libc.org/cgit/musl/tree/src/network/lookup_serv.c#n53 Modules/getaddrinfo should be fixed. The configure script should detect whether the system getaddrinfo is broken. If so, a wrapper that checks numeric services, and returns EAI_SERVICE or calls the system getaddrinfo should be used in place of the system getaddrinfo. |
