commit 868baf07 upstream. When the fuction graph tracer starts, it needs to make a special stack for each task to save the real return values of the tasks. All running tasks have this stack created, as well as any new tasks. On CPU hot plug, the new idle task will allocate a stack as well when init_idle() is called. The problem is that cpu hotplug does not create a new idle_task. Instead it uses the idle task that existed when the cpu went down. ftrace_graph_init_task() will add a new ret_stack to the task that is given to it. Because a clone will make the task have a stack of its parent it does not check if the task's ret_stack is already NULL or not. When the CPU hotplug code starts a CPU up again, it will allocate a new stack even though one already existed for it. The solution is to treat the idle_task specially. In fact, the function_graph code already does, just not at init_idle(). Instead of using the ftrace_graph_init_task() for the idle task, which that function expects the task to be a clone, have a separate ftrace_graph_init_idle_task(). Also, we will create a per_cpu ret_stack that is used by the idle task. When we call ftrace_graph_init_idle_task() it will check if the idle task's ret_stack is NULL, if it is, then it will assign it the per_cpu ret_stack. Reported-by:

commit f8626854 upstream. mm_fault_error() should not execute oom-killer, if page fault occurs in kernel space. E.g. in copy_from_user()/copy_to_user(). This would happen if we find ourselves in OOM on a copy_to_user(), or a copy_from_user() which faults. Without this patch, the kernels hangs up in copy_from_user(), because OOM killer sends SIG_KILL to current process, but it can't handle a signal while in syscall, then the kernel returns to copy_from_user(), reexcute current command and provokes page_fault again. With this patch the kernel return -EFAULT from copy_from_user(). The code, which checks that page fault occurred in kernel space, has been copied from do_sigbus(). This situation is handled by the same way on powerpc, xtensa, tile, ... Signed-off-by:

commit bf3a1eb8 upstream. When au1000_eth probes the MII bus for PHY address, if we do not set au1000_eth platform data's phy_search_highest_address, the MII probing logic will exit early and will assume a valid PHY is found at address 0. For MTX-1, the PHY is at address 31, and without this patch, the link detection/speed/duplex would not work correctly. Signed-off-by:

commit f08dc1ac upstream. ata_qc_complete() contains special handling for certain commands. For example, it schedules EH for device revalidation after certain configurations are changed. These shouldn't be applied to EH commands but they were. In most cases, it doesn't cause an actual problem because EH doesn't issue any command which would trigger special handling; however, ACPI can issue such commands via _GTF which can cause weird interactions. Restructure ata_qc_complete() such that EH commands are always passed on to __ata_qc_complete(). stable: Please apply to -stable only after 2.6.38 is released. Signed-off-by:

commit 8909c9ad upstream. Since a8f80e8f any process with CAP_NET_ADMIN may load any module from /lib/modules/. This doesn't mean that CAP_NET_ADMIN is a superset of CAP_SYS_MODULE as modules are limited to /lib/modules/**. However, CAP_NET_ADMIN capability shouldn't allow anybody load any module not related to networking. This patch restricts an ability of autoloading modules to netdev modules with explicit aliases. This fixes CVE-2011-1019. Arnd Bergmann suggested to leave untouched the old pre-v2.6.32 behavior of loading netdev modules by name (without any prefix) for processes with CAP_SYS_MODULE to maintain the compatibility with network scripts that use autoloading netdev modules by aliases like "eth0", "wlan0".

Commit: e8e5c215 upstream When CPU hotplug is used, some CPUs may be offline at the time a kexec is performed. The subsequent kernel may expect these CPUs to be already running, and will declare them stuck. On pseries, there's also a soft-offline (cede) state that CPUs may be in; this can also cause problems as the kexeced kernel may ask RTAS if they're online -- and RTAS would say they are. The CPU will either appear stuck, or will cause a crash as we replace its cede loop beneath it. This patch kicks each present offline CPU awake before the kexec, so that none are forever lost to these assumptions in the subsequent kernel. Now, the behaviour is that all available CPUs that were offlined are now online & usable after the kexec. This mimics the behaviour of a full reboot (on which all CPUs will be restarted).

commit d504bed6 upstream. Currently for kexec the PTE tear down on 1TB segment systems normally requires 3 hcalls for each PTE removal. On a machine with 32GB of memory it can take around a minute to remove all the PTEs. This optimises the path so that we only remove PTEs that are valid. It also uses the read 4 PTEs at once HCALL. For the common case where a PTEs is invalid in a 1TB segment, this turns the 3 HCALLs per PTE down to 1 HCALL per 4 PTEs. This gives an > 10x speedup in kexec times on PHYP, taking a 32GB machine from around 1 minute down to a few seconds. Signed-off-by:

commit f90ece28 upstream. This adds plpar_pte_read_4_raw() which can be used read 4 PTEs from PHYP at a time, while in real mode. It also creates a new hcall9 which can be used in real mode. It's the same as plpar_hcall9 but minus the tracing hcall statistics which may require variables outside the RMO. Signed-off-by:

commit 095c7965 upstream. Author: Milton Miller <miltonm@bga.com> On large machines we are running out of room below 256MB. In some cases we only need to ensure the allocation is in the first segment, which may be 256MB or 1TB. Add slb0_limit and use it to specify the upper limit for the irqstack and emergency stacks. On a large ppc64 box, this fixes a panic at boot when the crashkernel= option is specified (previously we would run out of memory below 256MB). Signed-off-by:

commit 5d7a8721 upstream. I saw this in a kdump kernel: IOMMU table initialized, virtual merging enabled Interrupt 155954 (real) is invalid, disabling it. Interrupt 155953 (real) is invalid, disabling it. ie we took some spurious interrupts. default_machine_crash_shutdown tries to disable all interrupt sources but uses chip->disable which maps to the default action of: static void default_disable(unsigned int irq) { } If we use chip->shutdown, then we actually mask the IRQ: static void default_shutdown(unsigned int irq) { struct irq_desc *desc = irq_to_desc(irq); desc->chip->mask(irq); desc->status |= IRQ_MASKED; } Not sure why we don't implement a ->disable action for xics.c, or why default_disable doesn't mask the interrupt.

commit 06440794 upstream. We wrap the crash_shutdown_handles[] calls with longjmp/setjmp, so if any of them fault we can recover. The problem is we add a hook to the debugger fault handler hook which calls longjmp unconditionally. This first part of kdump is run before we marshall the other CPUs, so there is a very good chance some CPU on the box is going to page fault. And when it does it hits the longjmp code and assumes the context of the oopsing CPU. The machine gets very confused when it has 10 CPUs all with the same stack, all thinking they have the same CPU id. I get even more confused trying to debug it. The patch below adds crash_shutdown_cpu and uses it to specify which cpu is in the protected region. Since it can only be -1 or the oopsing CPU, we don't need to use memory barriers since it is only valid on the local CPU - no other CPU will ever see a value that matches it's local CPU id. Eventually we should switch the order and marshall all CPUs before doing the crash_shutdown_handles[] calls, but that is a bigger fix. Signed-off-by:

Hugh Dickins authored
commit a3e8cc64 upstream. Robert Swiecki reported a BUG_ON(page_mapped) from a fuzzer, punching a hole with madvise(,, MADV_REMOVE). That path is under mutex, and cannot be explained by lack of serialization in unmap_mapping_range(). Reviewing the code, I found one place where vm_truncate_count handling should have been updated, when I switched at the last minute from one way of managing the restart_addr to another: mremap move changes the virtual addresses, so it ought to adjust the restart_addr. But rather than exporting the notion of restart_addr from memory.c, or converting to restart_pgoff throughout, simply reset vm_truncate_count to 0 to force a rescan if mremap move races with preempted truncation. We have no confirmation that this fixes Robert's BUG, but it is a fix that's worth making anyway. Signed-off-by:

commit d11327ad upstream. NETDEV_NOTIFY_PEER is an explicit request by the driver to send a link notification while NETDEV_UP/NETDEV_CHANGEADDR generate link notifications as a sort of side effect. In the later cases the sysctl option is present because link notification events can have undesired effects e.g. if the link is flapping. I don't think this applies in the case of an explicit request from a driver. This patch makes NETDEV_NOTIFY_PEER unconditional, if preferred we could add a new sysctl for this case which defaults to on. This change causes Xen post-migration ARP notifications (which cause switches to relearn their MAC tables etc) to be sent by default. Signed-off-by:
