This is diferent from # legacy clone() where the "stack" argument had to point to the lowest # or highest address of the stack depending on the architecture. # # clone3() was released with 5.3. Currently, it is not documented and # very unclear to userspace how the stack and stack_size argument have # to be passed. After talking to glibc folks we concluded that changing # clone3() to determine stack direction and doing basic validation is # the right course of action. # # Note, this is a potentially user visible change. In the very unlikely # case, that it breaks someone's use-case we will revert. (And then e.g. # place the new behavior under an appropriate flag.) # # Note that passing an empty stack will continue working just as before. # Breaking someone's use-case is very unlikely. Neither glibc nor musl # currently expose a wrapper for clone3(). There is currently also no # real motivation for anyone to use clone3() directly. First, because # using clone{3}() with stacks requires some assembly (see glibc and # musl). Second, because it does not provide features that legacy # clone() doesn't. New features for clone3() will first happen in v5.5 # which is why v5.4 is still a good time to try and make that change now # and backport it to v5.3. # # I did a codesearch on https://codesearch.debian.net, github, and # gitlab and could not find any software currently relying directly on # clone3(). I expect this to change once we land CLONE_CLEAR_SIGHAND # which was a request coming from glibc at which point they'll likely # start using it" # # * tag 'for-linus-2019-11-05' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: # clone3: validate stack arguments # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux-ld --version # < git log --format=%s --max-count=1 26bc672134241a080a83b2ab9aa8abede8d30e1c # < make -s -j 80 ARCH=s390 O=/kisskb/build/linus_s390-defconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- defconfig # make -s -j 80 ARCH=s390 O=/kisskb/build/linus_s390-defconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- Completed OK # rm -rf /kisskb/build/linus_s390-defconfig_s390x-gcc8 # Build took: 0:04:22.937255
