AndyPang created MESOS-4577: ------------------------------- Summary: libprocess can not run on 16-byte aligned stack mandatory architecture(aarch64 ppc64) Key: MESOS-4577 URL: https://issues.apache.org/jira/browse/MESOS-4577 Project: Mesos Issue Type: Bug Components: containerization, libprocess, stout Environment: Linux 10-175-112-202 4.1.6-rc3.aarch64 #1 SMP Mon Oct 12 01:43:03 UTC 2015 aarch64 aarch64 aarch64 GNU/Linux Reporter: AndyPang
libprocess 3rdparty stout library(in linux.hpp) packaging a syscall "clone" : {code:title=clone|borderStyle=solid} inline pid_t clone(const lambda::function<int()>& func, int flags) { // Stack for the child. // - unsigned long long used for best alignment. // - 8 MiB appears to be the default for "ulimit -s" on OSX and Linux. // // NOTE: We need to allocate the stack dynamically. This is because // glibc's 'clone' will modify the stack passed to it, therefore the // stack must NOT be shared as multiple 'clone's can be invoked // simultaneously. int stackSize = 8 * 1024 * 1024; unsigned long long *stack = new unsigned long long[stackSize/sizeof(unsigned long long)]; pid_t pid = ::clone( childMain, &stack[stackSize/sizeof(stack[0]) - 1], // stack grows down. flags, (void*) &func); // If CLONE_VM is not set, ::clone would create a process which runs in a // separate copy of the memory space of the calling process. So we destroy the // stack here to avoid memory leak. If CLONE_VM is set, ::clone would create a // thread which runs in the same memory space with the calling process. if (!(flags & CLONE_VM)) { delete[] stack; } return pid; } {code} syscal "clone" parameter stack is 8-byte aligned,so if in 16-byte aligned stack mandatory architecture(aarch64 ppc64) it will get error. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
