Summary: Fix SIGBUS on ARM64/AArch64
Key: MESOS-6835
URL: https://issues.apache.org/jira/browse/MESOS-6835
Project: Mesos
Issue Type: Bug
Components: security, stout
Reporter: Aaron Wood
Assignee: Aaron Wood
Currently in the Linux launcher when the stack is allocated and prepared for a
call to clone() it is not properly aligned. This is not an issue for x86 or x64
but for ARM64/AArch64 it is because of the requirement of having the stack
aligned to a 16 byte boundary. While x86 and x64 also expect the stack to have
a 16 byte aligned stack, it is not enforced.
Additionally, the way that the stack is currently allocated and passed to
clone() accidentally chops off one entry, making a stack overflow using those
missing 8 bytes a possibility. Fixing this while aligning the memory will fix
both the issue of the stack overflow issue as well as the SIGBUS crash.
