[opensuse] Why is Leap 42.2 missing /usr/include/sys/random.h?? (and no getrandom in linux/random.h)
All, getrandom() was added with the 3.17 kernel, yet Leap 42.2 does not contain a prototype in /usr/include/linux/random.h and does not include /usr/include/sys/random.h at all. Anybody know why?? -- David C. Rankin, J.D.,P.E. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Yes, yes, I have glibc-devel installed and I have /usr/include/linux/random.h, but notice: it does not contain a prototype for getrandom() that's the funky missing part. With arch, it is now in sys/random.h, but for leap, it should be in linux/random.h -- at least according to the man page on Leap. Checkout man getrandom. Why is the prototype missing? -- David C.

Just had a look on my 42.3 system, man getrandom bring up the man page and gives prototype int getrandom(void *buf, size_t buflen, unsigned int flags); and clearly states "#include <linux/random.h>" find finds: /usr/include/linux/random.h and rpm says that it comes from: linux-glibc-devel-4.4-5.4.noarch and the man page comes from man-pages-4.02-9.4.noarch but grepping /usr/include/linux/random.h for getrandom only brings up * Flags for getrandom(2) I smell a bug, definitely in the man page but more important in the missing getrandom prototype. Have a look at the Arch man page, maybe that will give a clue as to where it's disappeared to.

Yes, that indeed does provide a hint that something is in fact missing from linux/random.h and howto workaround the problem, but is this a BUG? Why on earth would we have a man page for getrandom(), but then the implementation is actually missing from the stated header? The quote: "It appears that some Linux systems have a man page for getrandom and the correct syscall definitions, but no C function." doesn't quite answer that question. To me, is looks like a bug, walks like a bug and quacks like a bug.... that leaves you either (1) implementing the workaround function, (2) drawing from /dev/urandom, or (3) polling /dev/random -- all of which the getrandom() function was implemented to avoid having to do :( -- David C.

It is indeed a bug but the question is, is it a kernel bug or is it a glibc bug or is it only a man pages bug? Dave P -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

This is kernel header, why should it contain user-space prototypes.
that's the funky missing part. With arch, it is now in sys/random.h, but
Compare glibc versions.
for leap, it should be in linux/random.h -- at least according to the man page on Leap. Checkout man getrandom.
man page is completely independent of either kernel or glibc. And this is already fixed in actual man-pages.
Why is the prototype missing?
Because it has never been in this file in the first place and glibc in Leap is too old to provide another file.

Andrei, I completely disagree. getrandom() is a user-space function. If it wasn't fixed in Leap 42.3 by implementing the prototype in linux/random.h, then it was not fixed correctly. -- David C.

Quoting David C. Rankin <drankinatty@suddenlinkmail.com>:
All,
getrandom() was added with the 3.17 kernel, yet Leap 42.2 does not contain a prototype in /usr/include/linux/random.h and does not include /usr/include/sys/random.h at all. Anybody know why??
