* x86: protect against sigaltstack wraparoundRoland McGrath2008-01-301-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cf http://lkml.org/lkml/2007/10/3/41 To summarize: on Linux, SA_ONSTACK decides whether you are already on the signal stack based on the value of the SP at the time of a signal. If you are not already inside the range, you are not "on the signal stack" and so the new signal handler frame starts over at the base of the signal stack. sigaltstack (and sigstack before it) was invented in BSD. There, the SA_ONSTACK behavior has always been different. It uses a kernel state flag to decide, rather than the SP value. When you first take an SA_ONSTACK signal and switch to the alternate signal stack, it sets the SS_ONSTACK flag in the thread's sigaltstack state in the kernel. Thereafter you are "on the signal stack" and don't switch SP before pushing a handler frame no matter what the SP value is. Only when you sigreturn from the original handler context do you clear the SS_ONSTACK flag so that a new handler frame will start over at the base of the alternate signal stack. The undesireable effect of the Linux behavior is that an overflow of the alternate signal stack can not only go undetected, but lead to a ring buffer effect of clobbering the original handler frame at the base of the signal stack for each successive signal that comes just after the overflow. This is what Shi Weihua's test case demonstrates. Normally this does not come up because of the signal mask, but the test case uses SA_NODEFER for its SIGSEGV handler. The other subtle part of the existing Linux semantics is that a simple longjmp out of a signal handler serves to take you off the signal stack in a safe and reliable fashion without having used sigreturn (nor having just returned from the handler normally, which means the same). After the longjmp (or even informal stack switching not via any proper libc or kernel interface), the alternate signal stack stands ready to be used again. A paranoid program would allocate a PROT_NONE red zone around its alternate signal stack. Then a small overflow would trigger a SIGSEGV in handler setup, and be fatal (core dump) whether or not SIGSEGV is blocked. As with thread stack red zones, that cannot catch all overflows (or underflows). e.g., a local array as large as page size allocated in a function called from a handler, but not actually touched before more calls push more stack, could cause an overflow that silently pushes into some unrelated allocated pages. The BSD behavior does not do anything in particular about overflow. But it does at least avoid the wraparound or "ring buffer effect", so you'll just get a straightforward all-out overflow down your address space past the low end of the alternate signal stack. I don't know what the BSD behavior is for longjmp out of an SA_ONSTACK handler. The POSIX wording relating to sigaltstack is pretty minimal. I don't think it speaks to this issue one way or another. (The program that overflows its stack is clearly in undefined behavior territory of one sort or another anyhow.) Given the longjmp issue and the potential for highly subtle complications in existing programs relying on this in arcane ways deep in their code, I am very dubious about changing the behavior to the BSD style persistent flag. I think Shi Weihua's patches have a similar effect by tracking the SP used in the last handler setup. I think it would be sensible for the signal handler setup code to detect when it would itself be causing a stack overflow. Maybe something like the following patch (untested). This issue exists in the same way on all machines, so ideally they would all do a similar check. When it's the handler function itself or its callees that cause the overflow, rather than the signal handler frame setup alone crossing the boundary, this still won't help. But I don't see any way to distinguish that from the valid longjmp case. Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

* x86: provide a DMI based port 0x80 I/O delay override.Rene Herman2008-01-308-10/+129
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | x86: provide a DMI based port 0x80 I/O delay override. Certain (HP) laptops experience trouble from our port 0x80 I/O delay writes. This patch provides for a DMI based switch to the "alternate diagnostic port" 0xed (as used by some BIOSes as well) for these. David P. Reed confirmed that port 0xed works for him and provides a proper delay. The symptoms of _not_ working are a hanging machine, with "hwclock" use being a direct trigger. Earlier versions of this attempted to simply use udelay(2), with the 2 being a value tested to be a nicely conservative upper-bound with help from many on the linux-kernel mailinglist but that approach has two problems. First, pre-loops_per_jiffy calibration (which is post PIT init while some implementations of the PIT are actually one of the historically problematic devices that need the delay) udelay() isn't particularly well-defined. We could initialise loops_per_jiffy conservatively (and based on CPU family so as to not unduly delay old machines) which would sort of work, but... Second, delaying isn't the only effect that a write to port 0x80 has. It's also a PCI posting barrier which some devices may be explicitly or implicitly relying on. Alan Cox did a survey and found evidence that additionally some drivers may be racy on SMP without the bus locking outb. Switching to an inb() makes the timing too unpredictable and as such, this DMI based switch should be the safest approach for now. Any more invasive changes should get more rigid testing first. It's moreover only very few machines with the problem and a DMI based hack seems to fit that situation. This also introduces a command-line parameter "io_delay" to override the DMI based choice again: io_delay=<standard|alternate> where "standard" means using the standard port 0x80 and "alternate" port 0xed. This retains the udelay method as a config (CONFIG_UDELAY_IO_DELAY) and command-line ("io_delay=udelay") choice for testing purposes as well. This does not change the io_delay() in the boot code which is using the same port 0x80 I/O delay but those do not appear to be a problem as David P. Reed reported the problem was already gone after using the udelay version. He moreover reported that booting with "acpi=off" also fixed things and seeing as how ACPI isn't touched until after this DMI based I/O port switch I believe it's safe to leave the ones in the boot code be. The DMI strings from David's HP Pavilion dv9000z are in there already and we need to get/verify the DMI info from other machines with the problem, notably the HP Pavilion dv6000z. This patch is partly based on earlier patches from Pavel Machek and David P. Reed.

| | | | | | | | | | | | | | | | | | | | | | | Michael Opdenacker reported: For backward compatibility with earlier (< 2.6.24) kernels, arch/i386/boot/bzImage or arch/x86_64/boot/bzImage symbolic links to arch/x86/boot/bzImage are created when you build an x86 kernel. The arch/i386 or arch/x86_64 directories are then created for this only purpose. Issue: these generated directories and symbolic links are *not cleaned up* when you run "make mrproper" (and thus "make distclean"). This disturbs the production of patches, because the source tree is left with generated files and directories. Sam has an alternative fix: The directory is killed during make clean as opposed to make mrproper.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Neither is the mips_rtc_get_time() routine defined anywhere in the MIPS architecture-specific code, nor does anyone call it any more. This patch removes the extern declaration of this fossil. This patch does not introduce any functional changes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Qemu platform was originally implemented to have an easily supportable platform until Qemu reaches a state where it emulates a real world system. Since the latest release Qemu is capable of emulating the MIPSsim and Malta platforms, so this goal has been reached. The Qemu plaform is also rather underfeatured so less useful than a Malta emulation. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
