Subject: [PATCH v7 0/4] Add close_range, closefrom, and posix_spawn_file_actions_closefrom_np
Date: Tue, 6 Jul 2021 11:58:35 -0300 [thread overview]
Message-ID: <20210706145839.1658623-1-adhemerval.zanella@linaro.org> (raw)
Linux v5.9 added a new close_range syscall, which allows the caller to
issue the kernel to close or set close-on-exec on a range of file
descriptors.
This patchset export the syscall along with two GNU extensions:
closefrom, with similar semantics from other systems ((Solaris, OpenBSD,
NetBSD, FreeBSD); and posix_spawn_file_actions_closefrom_np, which
allows use close_range semantic on posix_spawn().
The first patch is libsupport one for the tests. The second patch adds
the Linux specific close_range syscall. The third adds the GNU extension
closefrom(), which use close_range() if available. The firth adds the
posix_spawn extension.
Adhemerval Zanella (4):
support: Add support_stack_alloc
linux: Add close_range
io: Add closefrom [BZ #10353]
posix: Add posix_spawn_file_actions_addclosefrom_np
