6 years agoFix preventing memory allocation in signal handler (#16485)
Jan Vorlicek [Fri, 23 Feb 2018 09:40:54 +0000 (10:40 +0100)]
Fix preventing memory allocation in signal handler (#16485)

There was a subtle bug. When the hardware exception handler returns back
to the signal handler, the exception's CONTEXT record may contain
modified registers and so the changes need to be propagated back to the
signal context. But the recent change #16384 was restoring the signal
context from the originally grabbed context instead of the one that's
pointed to by the exception, which is different.

I have also added a little optimization - the contextRecord that was
added is not needed, since the signalContextRecord can be used as the
initial context record for the exception. So we can save the
contextRecord and also copying to the signalContextRecord from it.

Fix ARM/ARM64 hijacking in tail calls (#16039)

* Fix ARM/ARM64 hijacking in tail calls

This change fixes an issue that can happen when a function that has tail
calls is hijacked. There are two potential issues:

1. When a function that tail calls another one is hijacked, the LR may be
stored at a different location in the stack frame of the tail call
target.
So just by performing tail call, the hijacked location becomes invalid and
unhijacking would corrupt stack by writing to that location.

2. There is a small window after the caller pops LR from the stack in its
epilog and before the tail called function pushes LR in its prolog when
the hijacked return address would not be not on the stack and so we would
not be able to unhijack.

The fix is to prevent hijacking of functions that contain tail calls.

* Enable the tailcall hijacking test for ARM64

The test JIT/Methodical/tailcall_v4/hijacking should be passing now on
ARM64.
