This issue leads to failures in network-related\r\nfunctions that rely on `getaddrinfo()`, such as Python's `urllib3`\r\nlibrary, which passes the result directly to `connect()`. This results\r\nin connection attempts using a port value of 0, which naturally fails.\r\n\r\n### Minimal example to reproduce the problem\r\n```c\r\n#include <arpa/inet.h>\r\n#include <netdb.h>\r\n#include <stdio.h>\r\n\r\nint main(void) {\r\n    struct addrinfo *res = NULL;\r\n    getaddrinfo(\"google.com\", \"443\", NULL, &res);\r\n\r\n    for (struct addrinfo *i = res; i != NULL; i = i->ai_next) {\r\n        char str[INET6_ADDRSTRLEN];\r\n        if (i->ai_addr->sa_family == AF_INET) {\r\n            struct sockaddr_in *p = (struct sockaddr_in *)i->ai_addr;\r\n            int port = ntohs(p->sin_port);\r\n            printf(\"%s: %i\\n\", inet_ntop(AF_INET, &p->sin_addr, str, sizeof(str)), port);\r\n        } else if (i->ai_addr->sa_family == AF_INET6) {\r\n            struct sockaddr_in6 *p = (struct sockaddr_in6 *)i->ai_addr;\r\n            int port = ntohs(p->sin6_port);\r\n            printf(\"%s: %i\\n\", inet_ntop(AF_INET6, &p->sin6_addr, str, sizeof(str)), port);\r\n        }\r\n    }\r\n\r\n    return 0;\r\n}\r\n```\r\n```\r\n$ /opt/wasi-sdk/bin/clang -target wasm32-wasip2 -o foo foo.c\r\n$ wasmtime run -S allow-ip-name-lookup=y foo\r\n216.58.211.238: 0\r\n2a00:1450:4026:808::200e: 0\r\n```\r\nExpected output:\r\n```\r\n216.58.211.238: 443\r\n2a00:1450:4026:808::200e: 443\r\n```\r\n### Root Cause\r\n\r\nThe root cause is that `getaddrinfo()` does not correctly translate the\r\nprovided service into a port number. As described in the `getaddrinfo()`\r\nman [page](https://man7.org/linux/man-pages/man3/getaddrinfo.3.html),\r\nthe function should:\r\n\r\n> service sets the port in each returned address structure. If\r\nthis argument is a service name (see\r\n[services(5)](https://man7.org/linux/man-pages/man5/services.5.html)),\r\nit is\r\ntranslated to the corresponding port number. This argument can\r\nalso be specified as a decimal number, which is simply converted\r\nto binary. If service is NULL, then the port number of the\r\nreturned socket addresses will be left uninitialized.\r\n\r\n### Proposed Fix\r\n\r\nThis pull request addresses the issue by implementing the following\r\nbehavior for `getaddrinfo()`:\r\n\r\n* If the service is `NULL`, the port number in the returned socket\r\naddresses remains uninitialized.\r\n* The value is converted to an integer and validated if the service is\r\nnumeric.\r\n\r\nThe PR does not currently add support for translating named services\r\ninto port numbers because `getservbyname()` has not been implemented. In\r\ncases where a named service is provided, the `EAI_NONAME` error code is\r\nreturned.","shortMessageHtmlLink":"getaddrinfo: improve the service/port resolution (<a class=\"issue-link js-issue-link\" data-error-text=\"Failed to load title\" data-id=\"2446275113\" data-permission-text=\"Title is private\" data-url=\"https://github.com/WebAssembly/wasi-libc/issues/524\" data-hovercard-type=\"pull_request\" data-hovercard-url=\"/WebAssembly/wasi-libc/pull/524/hovercard\" href=\"https://github.com/WebAssembly/wasi-libc/pull/524\">#524</a>)"}},{"before":"8279f9591a066aa4930ac07b9a5b590aaf9740a7","after":"3f812abfb20a21c1427270aa8a59c5e2ddf8c7d3","ref":"refs/heads/main","pushedAt":"2024-08-28T00:01:22.000Z","pushType":"pr_merge","commitsCount":1,"pusher":{"login":"abrown","name":"Andrew Brown","path":"/abrown","primaryAvatarUrl":"https://avatars.githubusercontent.com/u/541880?s=80&v=4"},"commit":{"message":"fix shared library build with llvm-19 (#526)","shortMessageHtmlLink":"fix shared library build with llvm-19 (<a class=\"issue-link js-issue-link\" data-error-text=\"Failed to load title\" data-id=\"2462535851\" data-permission-text=\"Title is private\" data-url=\"https://github.com/WebAssembly/wasi-libc/issues/526\" data-hovercard-type=\"pull_request\" data-hovercard-url=\"/WebAssembly/wasi-libc/pull/526/hovercard\" href=\"https://github.com/WebAssembly/wasi-libc/pull/526\">#526</a>)"}},{"before":"230d4be6c54bec93181050f9e25c87150506bdd0","after":"8279f9591a066aa4930ac07b9a5b590aaf9740a7","ref":"refs/heads/main","pushedAt":"2024-08-27T23:42:48.000Z","pushType":"pr_merge","commitsCount":1,"pusher":{"login":"abrown","name":"Andrew Brown","path":"/abrown","primaryAvatarUrl":"https://avatars.githubusercontent.com/u/541880?s=80&v=4"},"commit":{"message":"Exclude setjmp runtime from LTO (#529)\n\nThis fixes errors like:\r\n```\r\nwasm-ld: error: /Volumes/PortableSSD/git/wasi-sdk/build/install/bin/../share/wasi-sysroot/lib/wasm32-wasi/llvm-lto/19.1.0-wasi-sdk/libsetjmp.a(rt.o): attempt to add bitcode file after LTO (__wasm_longjmp)\r\n```\r\n\r\nNote: Any symbol that the compiler might generate at bitcode compile\r\ntime either need to be unconditionally included at LTO time, or not\r\nbuilt as LTO.
