Add memfd_create() and constants MFD_ALLOW_SEALING, MFD_CLOEXEC to the os module. A glibc wrapper for memfd_create() is not available yet but the interface has been standardized.http://man7.org/linux/man-pages/man2/memfd_create.2.htmlhttps://dvdhrm.wordpress.com/tag/memfd/

Maybe useful at mmapmodule.c replacing        /* SVR4 method to map anonymous memory is to open /dev/zero */        fd = devzero = _Py_open("/dev/zero", O_RDWR);tagname is unused at UNIX version of new_mmap_object() so if provided something like could be added for Linux only        fd = memfd_create(tagname, O_RDWR);

https://buildbot.python.org/all/#builders/99/builds/2738 is failing because some HUGE TLB constants are not defined on Gentoo.

Davin, Pierre, it looks like this could simplify lifetime management of shared memory pools, what do you think?
msg344302 -(view)Author: Pierre Glaser (pierreglaser)*Date: 2019-06-02 19:03
From a quick skim at the man page of memfd_create, this looks promising.

It seems like this issue can now be closed, no?
msg344685 -(view)Author: Christian Heimes (christian.heimes)*(Python committer)Date: 2019-06-05 08:46
Yes, the feature is implemented and buildbots are green.
