-Subject: [PATCH] Fix build with musl and older Linux kernel
-
-The musl libc carries its own copy of Linux system calls. When building
-with Linux headers older than v3.17, musl provides SYS_getrandom
-definition, but not GRND_NONBLOCK. This causes build failure for
-libressl and openntpd:
-
-getentropy_linux.c: In function 'getentropy_getrandom':
-getentropy_linux.c:205:42: error: 'GRND_NONBLOCK' undeclared (first use in this function)
-   ret = syscall(SYS_getrandom, buf, len, GRND_NONBLOCK);
-                                          ^~~~~~~~~~~~~
-
-Define GRND_NONBLOCK locally when its definition is missing to fix the
-build. There should be no run-time effect. Older kernels return ENOSYS
-for unsupported syscall().
