In my comments on v1 of this patch I wrote: "I think all the uses of sigprocmask() in linux-user/signal.c also need to be do_sigprocmask(), as they are the guest trying to control its signal mask (via the mask it specifies for running signal handlers, or the mask it passes back when restoring context on return from a signal handler)." ...but I don't see those changes here. -- PMM
