0eb4263705 Make sure the i386 sysv stack is aligned 
The previous fix had a typo in which the wrong offset was used which
meant that the alignment still wasn't correct. Fix this properly now.

e286649f08 Make sure the i386 sysv stack is aligned 
SysV ABI requires a stack alignment of 16 bytes. Currently, for i386
with SysV ABI, the trampoline function is entered with an unaligned
stack. This causes problems for the context-function that is jumped to
as its stack is also unaligned. This causes a crash for our use-case
because the context function contains an SSE instruction which reads
from the stack. The SSE instruction requires the correct alignment.
Fix it by changing the 0x2c offset to 0x30, such that the stack remains
aligned.

Add shadow stack support for fcontext
 2022-09-30 15:31:01 +02:00

3484575878 Add shadow stack support for fcontext 
Shadow stack is part of Intel's Control-Flow Enforcement Technology.

    Whenever a function is called, the return address is pushed onto both
    the regular stack and the shadow stack. When that function returns, the
    return addresses are popped off both stacks and compared; if they fail
    to match, #CP raised.

    Backport this commit from https://github.com/php/php-src/pull/9283
    With this commit, we create shadow stack with syscall map_shadow_stack
    (no.451) for each fiber context and switch the shadow stack accordingly
    during fcontext switch.

b62a991ee6 Add support for Indirect Branch Tracking (IBT) 
Indirect Branch Tracking(IBT) is part of Intel's Control-Flow
Enforcement Technology(CET). IBT is hardware based, forward edge
Control-Flow-Integrity mechanism where any indirect CALL/JMP must
target an ENDBR instruction or suffer #CP.

This commit inserts endbr64 instruction in assembly to support IBT.
