Fortunately `pipe2` can\nstand in for `pipe` by passing flags of zero. Unfortunately the uclibc\ndefinition of `pipe2` is gated behind `UCLIBC_LINUX_SPECIFIC`. When\ncompiling with that config set to `n` (e.g. allnoconfig) we get a build\nerror when trying to call the function. Instead, just directly invoke\nthe syscall from the kernel via `INLINE_SYSCALL` when falling back to\n`pipe2` for implementing `pipe` on architectures without `__NR_pipe`.\n\nFixes: dde074b39 (\"pipe: Use pipe2 if arch does not have the pipe syscall\")\nSigned-off-by: Charles Mirabile <cmirabil@redhat.com>\n---\n libc/sysdeps/linux/common/pipe.c | 2 +-\n 1 file changed, 1 insertion(+), 1 deletion(-)", "diff": "diff --git a/libc/sysdeps/linux/common/pipe.c b/libc/sysdeps/linux/common/pipe.c\nindex d0809f074..15063e5c5 100644\n--- a/libc/sysdeps/linux/common/pipe.c\n+++ b/libc/sysdeps/linux/common/pipe.c\n@@ -13,7 +13,7 @@\n #if defined __NR_pipe2 && !defined __NR_pipe\n int pipe(int filedes[2])\n {\n-\treturn pipe2(filedes, 0);\n+\treturn INLINE_SYSCALL(pipe2, 2, filedes, 0);\n }\n /* If both are defined then use the pipe syscall */\n #else\n", "prefixes": [ "uclibc-ng-devel", "v1", "1/7" ] }
