Actually, there's one more problem; I have a tentative fix for sparc64, but not for sparc32 (yet). Basically, sparc is unlike all other architectures in this respect: normally, after do_signal() has handled a signal the syscall exit glue loops back, rechecks if we need to be rescheduled, if we need to deal with more signals, etc. As the result, we build all sigframes at once. sparc (and, until recently, alpha) normally calls do_signal() only once; sparc64 _may_ call it twice, but that's it. sparc32 may call it up to three times if we had userland window spill on entry. That has unpleasant results - for starters, delivery of SIGSEGV upon failure to set sigframe up is delayed unpredictably; we will take it only when we trap again. Moreover, sigsuspend() has inconsistent behaviour in case when we have several pending signals unmasked by new mask. E.g. if we do the following on anything but sparc block signals 1 and 2 set handlers for both get signals 1 and 2 sent to you sigsuspend(&emptyset) we'll get both handlers run. On sparc we'll get only one of them, except that if we get an IRQ while running in its handler, we'll get both run... What happens is that sparc (and alpha until it got fixed) sets up one sigframe and happily buggers off to userland; the first handler runs until we hit a trap. If that trap happens to be the call of sigreturn() in the end of handler, the first thing it'll do will be restoring the original sigmask. Anything else will leave sigmask alone, see that we have another pending signal and handle it... Anyway, the sparc64 part of fix follows; I'm still digging through the sparc32 side of things.
