Will be nice to have another arch(mips) support for uprobes.
It's basically ready to be merged - but it's triggering issues elsewhere
in the kernel which I have to resolve first.
The short version is that the memory special mapping created by uprobe
with VM_EXEC but not VM_READ permissions is not working but it's working
if I add VM_READ. That should not be necessary so something deep down
in the guts of arch/mips is wrong.
Weird, I have a testcase that explicitly tests VM_EXEC and !VM_READ that
works.
Do you have more information about the failure, I can look at it in the
simulator and see where it goes wrong.
Thanks,
