Node and cmpxchg kuser helper #8437

Closed peerchemist closed 10 years ago

peerchemist commented 10 years ago

Found this while trying to run node on Grsecurity (and PAX) enabled kernel on ARMv6 (raspberry pi). I've asked on grsecurity forum first: https://forums.grsecurity.net/viewtopic.php?f=3&t=4052

You can see into that thread if you need more and possibly excesive information.

Problem is summed up by grsecurity author:

"Your nodejs binary is attempting to execute the cmpxchg kuser helper at its fixed address (0xffff0fc0)."

The responsible code is at: http://code.dyne.org/jmx/tree/node.js/deps/v8/src/atomicops_internals_arm_gcc.h?id=99bb8deb7d4d930854f51ad86ac8d9bc8efaf3b8

Sorry, we are not maintaining v8. This issue belongs here: http://code.google.com/p/v8/issues
