[issue10115] accept4 can fail with errno 90

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

There would need to be some tests.

Also, this last part of the patch looks strange:

@@ -3001,6 +3072,10 @@
             PyErr_SetString(PyExc_ValueError,
                             "can't use invalid socket value");
             return -1;
+#ifdef HAVE_ACCEPT4
+        /* These flags are not inherited after accept */
+        type &= ~(SOCK_NONBLOCK & SOCK_CLOEXEC);
+#endif /* HAVE_ACCEPT4 */


What is it meant for? And why does it come right after a "return" statement?
