[opensuse] What package provides glibc <sys/random.h>?
All, openSuSE install of glibc doesn't provide the /usr/include/sys/random.h header. What package does? e.g. http://man7.org/linux/man-pages/man2/getrandom.2.html On Arch $ pmqo /usr/include/sys/random.h /usr/include/sys/random.h is owned by glibc 2.25-7 Where is it on openSuSE?

I think no Leap package will provide it. There is one in the kernel source tree for kernel use. Maybe man(3) random for userland. For an out of tree kernel module maybe man(4) random?

glibc-devel I would suggest. that provides "/usr/include/linux/random.h" -- Per Jessen, Zürich (26.4°C) http://www.cloudsuisse.com/ - your owncloud, hosted in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Thanks guys, Yes, I have all the devel packages installed. These are functions *in user space* that can be used to control blocking of the random devices (/dev/random and /dev/urandom) when requesting data from the entropy pool. see: https://www.gnu.org/software/libc/manual/html_node/Unpredictable-Bytes.html#... I cannot believe they are not provided by the opensuse glibc package somewhere? It would be incomplete without them :( -- David C.

David, if I look up "man getrandom" (you mentioned that) on Leap, it's in <linux/random.h>. I guess there is something in <sys/random.h> that you need, but I can't tell what it is.

aha, getentropy() is missing, but getrandom() we have in <linux/random.h> -- Per Jessen, Zürich (25.2°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Thanks Per, Yes, I found getrandom() in linux.h. I was scratching my head over the discrepancy between the gcc reference stating: The getrandom function is declared in the header file sys/random.h. It is a GNU extension. and it being in linux/random.h in openSuSE? Even more bewildering is it is in sys/random.h on Arch. I suspect, but I could be wrong, that somewhere years ago, either getrandom() was originally in linux/random.h and it moved along with getentropy() to sys/random.h and openSuSE just kept it in the original location, or something similar. Do we need to file a bug to get getentropy() added to out glibc? -- David C.

Welcome to OpenSUSE... Following up on Pers post, I found /usr/include/linux/random.h is owned by linux-glibc-devel-4.4-5.4.noarch Just a *little bit*... different -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Where is it on openSuSE? (Leap 42.2) Nowhere. Because you will need to install glibc-2.25 to get it. Leap-42.2 is

Thank you Markus! That explains it. Who'd a thunk, 3 years to get getrandom() and a knock-down drag-out fight over wrappers. Funny how history works... -- David C.
