* uml: fix FP register corruptionJeff Dike2008-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit ee3d9bd4de1ed93d2a7ee41c331ed30a1c7b8acd ("uml: simplify SIGSEGV handling"), while greatly simplifying the kernel SIGSEGV handler that runs in the process address space, introduced a bug which corrupts FP state in the process. Previously, the SIGSEGV handler called the sigreturn system call by hand - it couldn't return through the restorer provided to it because that could try to call the libc restorer which likely wouldn't exist in the process address space. So, it blocked off some signals, including SIGUSR1, on entry to the SIGSEGV handler, queued a SIGUSR1 to itself, and invoked sigreturn. The SIGUSR1 was delivered, and was visible to the UML kernel after sigreturn finished. The commit eliminated the signal masking and the call to sigreturn. The handler simply hits itself with a SIGTRAP to let the UML kernel know that it is finished. UML then restores the process registers, which effectively longjmps the process out of the signal handler, skipping sigreturn's restoring of register state and the signal mask. The bug is that the host apparently sets used_fp to 0 when it saves the process FP state in the sigcontext on the process signal stack. Thus, when the process is longjmped out of the handler, its FP state is corrupt because it wasn't saved on the context switch to the UML kernel. This manifested itself as sleep hanging. For some reason, sleep uses floating point in order to calculate the sleep interval. When a page fault corrupts its FP state, it is faked into essentially sleeping forever. This patch saves the FP state before entering the SIGSEGV handler and restores it afterwards.

* Mark CC_STACKPROTECTOR as being BROKENLinus Torvalds2008-02-22
| | | | | | | | | | | | | | | | | | | | It's always been broken, but recent fixes actually made it do something, and now the brokenness shows up as the resulting kernel simply not working at all. So it used to be that you could enable this config option, and it just didn't do anything. Now we'd better stop people from enabling it by mistake, since it _does_ do something, but does it so badly as to be unusable. Code to actually make it work is pending, but incomplete and won't be merged into 2.6.25 in any case.

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2.6.25 has a regression where we can starve the scheduler by creating (N_SPES+1) contexts, then running them one at a time. The final context will never be run, as the other contexts are loaded on the SPEs, none of which are repoted as free (ie, spu->alloc_state != SPU_FREE), so spu_get_idle() doesn't give us a spu to run on. Because all of the contexts are stopped, none are descheduled by the scheduler tick, as spusched_tick returns if spu_stopped(ctx). This change replaces the spu_stopped() check with checking for SCHED_IDLE in ctx->policy. We set a context's policy to SCHED_IDLE when we're not in spu_run(). We also favour SCHED_IDLE contexts when looking for contexts to unbind, but leave their timeslice intact for later resumption.

There are two problems with this: 1) This is a total nightmare for the ioremap() implementation to keep various mappings of the same page coherent. 2) It's a total nightmare for the AGP code since it adds a ton of complexity in terms of keeping track of 2 different pointers to the same thing, in terms of error handling etc etc. This patch fixes this by making the AGP drivers use the new set_memory_XX APIs instead. Note: amd-k7-agp.c is built on Alpha too, and generic.c is built on ia64 as well, which do not yet have the set_memory_*() APIs, so for them some we have a few ugly #ifdefs - hopefully they'll be fixed soon.

| * | | x86: fix page_is_ram() thinkoArjan van de Ven2008-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | page_is_ram() has a special case for the 640k-1M bios area, however due to a thinko the special case checks the e820 table entry and not the memory the user has asked for. This patch fixes the bug. [ mingo@elte.hu: this too is better solved in the e820 space, but those fixes are too intrusive for v2.6.25. ] Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
| * | | x86: fix WARN_ON() message: teach page_is_ram() about the special 4Kb bios ↵Arjan van de Ven2008-02-19

This fixes the WARN_ON() reported by Laurent Riffard who was also very helpful in diagnosing the issue.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I suggest to make the vdso_install step independent as in following patch. This solves the issue at ahnd and still gives us the posibility to install the files should they be needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | change back the IO delay to 0x80. Alan says that 0xed is known to break some older boxes, and given that the get-rid-of-outb-APIs efforts are well underway we should just let them be finished.
