From 286286283e9bdc7ef894306e2dbcf4c115b97ba2 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Wed, 10 Mar 2021 12:26:31 -0300 Subject: linux: Add close_range It was added on Linux 5.9 (278a5fbaed89) with CLOSE_RANGE_CLOEXEC added on 5.11 (582f1fb6b721f). Although FreeBSD has added the same syscall, this only adds the symbol on Linux ports. This syscall is required to provided a fail-safe way to implement the closefrom symbol (BZ #10353). Checked on x86_64-linux-gnu and i686-linux-gnu on kernel 5.11 and 4.15. --- include/bits/unistd_ext.h | 6 ++++++ 1 file changed, 6 insertions(+) create mode 100644 include/bits/unistd_ext.h (limited to 'include/bits/unistd_ext.h') diff --git a/include/bits/unistd_ext.h b/include/bits/unistd_ext.h new file mode 100644 index 0000000000..277be05746 --- /dev/null +++ b/include/bits/unistd_ext.h @@ -0,0 +1,6 @@ +#include_next + +#ifndef _ISOMAC +extern int __close_range (unsigned int lowfd, unsigned int highfd, int flags); +libc_hidden_proto (__close_range); +#endif -- cgit v1.2.3
