Hello,
This is the very old bug initially reported by Evan in 2010, see
https://bugzilla.kernel.org/show_bug.cgi?id=16061
Somehow we forgot to fix it and now Pedro reports it again.
>From the changelog:
Note: in the longer term we should probably change setup_sigcontext()
to use get_flags() and then just remove this user_disable_single_step().
Yes, but this needs more changes. Lets start with more simple and
backportable fix. Also because I think that enable_single_step() and
the whole TIF_SINGLESTEP/TIF_FORCED_TF logic need some cleanups, but
I am not sure what we can do.
Oleg.
