* x86/vsyscall: allow seccomp filter in vsyscall=emulateWill Drewry2012-07-131-4/+31
| | | | | | | | | | | | | | | | | | | | If a seccomp filter program is installed, older static binaries and distributions with older libc implementations (glibc 2.13 and earlier) that rely on vsyscall use will be terminated regardless of the filter program policy when executing time, gettimeofday, or getcpu. This is only the case when vsyscall emulation is in use (vsyscall=emulate is the default). This patch emulates system call entry inside a vsyscall=emulate by populating regs->ax and regs->orig_ax with the system call number prior to calling into seccomp such that all seccomp-dependencies function normally. Additionally, system call return behavior is emulated in line with other vsyscall entrypoints for the trace/trap cases.

| | | | | | | | | | | | | | | | | | | | | | | | The macros just called BUG(), but that results in unused variable warnings all over the place, like in the IPMI driver. The build regression emails were annoying me, so here's the fix. I have not even compile tested this, but it's rather obvious.

In v3.5, it has at least the following problems: - warning dump during bootup - hang during suspend - prevents CORE powerdomain from entering retention during idle (even when no USB devices connected.) This demonstrates that this driver has not been thoroughly tested and therfore should not be enabled in the default defconfig. In addition, the problems above cause new PM regressions which need be addressed before this driver should be enabled in the default defconfig.

This prevents device low power states. The root cause is that the 32K sync timer IP block does not support smart-idle mode[1], and so the hwmod code keeps the IP block in no-idle mode while it is active. This in turn prevents the WKUP clockdomain from transitioning to idle. There is a hardcoded sleep dependency that prevents the CORE_L3 and CORE_CM clockdomains from transitioning to idle when the WKUP clockdomain is active[2], so the chip cannot enter any device low power states. It turns out that there is no need to take the 32k sync timer out of idle. The IP block itself probably does not have any native idle handling at all, due to its simplicity. Furthermore, the PRCM will never request target idle for this IP block while the kernel is running, due to the sleep dependency that prevents the WKUP clockdomain from idling while the CORE_L3 clockdomain is active. So we can safely leave the 32k sync timer in target-force-idle mode, even while we continue to access it. This workaround is implemented by defining a new clockdomain flag, CLKDM_ACTIVE_WITH_MPU, that indicates that the clockdomain is guaranteed to be active whenever the MPU is inactive. If an IP block's main functional clock exists inside this clockdomain, and the IP block does not support smart-idle modes, then the hwmod code will place the IP block into target force-idle mode even when enabled. The WKUP clockdomains on OMAP3/4 are marked with this flag. (On OMAP2xxx, no OCP header existed on the 32k sync timer.) Other clockdomains also should be marked with this flag, but those changes are deferred until a later merge window, to create a minimal fix. Another theoretically clean fix for this problem would be to implement PM runtime-based control for 32k sync timer accesses. These PM runtime calls would need to located in a custom clocksource, since the 32k sync timer is currently used as an MMIO clocksource. But in practice, there would be little benefit to doing so; and there would be some cost, due to the addition of unnecessary lines of code and the additional CPU overhead of the PM runtime and hwmod code - unnecessary in this case. Another possible fix would have been to modify the pm34xx.c code to force the IP block idle before entering WFI. But this would not have been an acceptable approach: we are trying to remove this type of centralized IP block idle control from the PM code.

In fact, the reset fixes that went upstream are exposing the problem more by causing BUG_ON() to trigger (which this patch turns into a WARN_ON instead). We need to be careful when using a variant of low power state that has the side effect of turning interrupts back on, to properly set all the SW & lazy state to look as if everything is enabled before we enter the low power state with MSR:EE off as we will return with MSR:EE on. If not, we have a discrepancy of state which can cause things to go very wrong later on. This patch moves the logic into a helper and uses it from the pseries and cell idle code. The power4/970 idle code already got things right (in assembly even !) so I'm not touching it. The power7 "bare metal" idle code is subtly different and correct. Remains PA6T and some hypervisor based Cell platforms which have questionable code in there, but they are mostly dead platforms so I'll fix them when I manage to get final answers from the respective maintainers about how the low power state actually works on them.

Conflicts: arch/arm/kernel/ptrace.c The new syscall restarting code can lead to problems if we take an interrupt in userspace just before restarting the svc instruction. If a signal is delivered when returning from the interrupt, the TIF_SYSCALL_RESTARTSYS will remain set and cause any syscalls executed from the signal handler to be treated as a restart of the previously interrupted system call. This includes the final sigreturn call, meaning that we may fail to exit from the signal context. Furthermore, if a system call made from the signal handler requires a restart via the restart_block, it is possible to clear the thread flag and fail to restart the originally interrupted system call. The right solution to this problem is to perform the restarting in the kernel, avoiding the possibility of handling a further signal before the restart is complete. Since we're almost at -rc6, let's revert the new method for now and aim for in-kernel restarting at a later date.
