2013-07-18s390/bpf,jit: address randomize and write protect jit codeHeiko Carstens1-5/+46
This is the s390 variant of 314beb9b "x86: bpf_jit_comp: secure bpf jit against spraying attacks". With this change the whole jit code and literal pool will be write protected after creation. In addition the start address of the jit code won't be always on a page boundary anymore. Signed-off-by: Heiko Carstens <[email protected]> Signed-off-by: Martin Schwidefsky <[email protected]>
2013-07-18s390/bpf,jit: use generic jit dumperHeiko Carstens1-8/+2
This is the s390 backend of 79617801 "filter: bpf_jit_comp: refactor and unify BPF JIT image dump output". Signed-off-by: Heiko Carstens <[email protected]> Signed-off-by: Martin Schwidefsky <[email protected]>
2013-07-18s390/bpf,jit: call module_free() from any contextHeiko Carstens1-17/+3
The workqueue workaround is no longer needed. Same as 5199dfe531 "sparc: bpf_jit_comp: can call module_free() from any context". Signed-off-by: Heiko Carstens <[email protected]> Signed-off-by: Martin Schwidefsky <[email protected]>
