Revision 372a8eaa05998cd45b3417d0e0ffd3a70978211a authored by Josh Poimboeuf on 17 July 2020, 14:04:25 UTC, committed by Thomas Gleixner on 22 July 2020, 21:47:47 UTC
The ORC unwinder fails to unwind newly forked tasks which haven't yet run on the CPU. It correctly reads the 'ret_from_fork' instruction pointer from the stack, but it incorrectly interprets that value as a call stack address rather than a "signal" one, so the address gets incorrectly decremented in the call to orc_find(), resulting in bad ORC data. Fix it by forcing 'ret_from_fork' frames to be signal frames.
