Needs cilium/ebpf#91 as well? |
|
yes, otherwise the ebpf library still generates the wrong position for src and dst registers on s390x. I'll check with @iii-i, what is blocking or the TODOs for that PR |

cilium/ebpf#91 seems merged. |

Load the full 32 bits word and take the lower 16 bits, instead of reading just 16 bits. Same fix as containers/crun@07bae05 Signed-off-by: Alice Frosi <afrosi@de.ibm.com>
The test cases need to take into account the assembly modifications.
The instruction:
LdXMemH dst: r2 src: r1 off: 0 imm: 0
has been replaced with:
LdXMemW dst: r2 src: r1 off: 0 imm: 0
And32Imm dst: r2 imm: 65535
