Structures kvm_vcpu_events, kvm_debugregs, kvm_pit_state2 and kvm_clock_data are copied to userland with some padding and reserved fields unitialized. It leads to leaking of contents of kernel stack memory. We have to initialize them to zero. In patch v1 Jan Kiszka suggested to fill reserved fields with zeros instead of memset'ting the whole struct. It makes sense as these fields are explicitly marked as padding.

2010-11-05KVM: Write protect memory after slot swapMichael S. Tsirkin1-4/+4
I have observed the following bug trigger: 1. userspace calls GET_DIRTY_LOG 2. kvm_mmu_slot_remove_write_access is called and makes a page ro 3. page fault happens and makes the page writeable fault is logged in the bitmap appropriately 4. kvm_vm_ioctl_get_dirty_log swaps slot pointers a lot of time passes 5. guest writes into the page 6. userspace calls GET_DIRTY_LOG At point (5), bitmap is clean and page is writeable, thus, guest modification of memory is not logged and GET_DIRTY_LOG returns an empty bitmap. The rule is that all pages are either dirty in the current bitmap, or write-protected, which is violated here. It seems that just moving kvm_mmu_slot_remove_write_access down to after the slot pointer swap should fix this bug. KVM-Stable-Tag. Signed-off-by: Michael S.

2010-11-01arch/tile: mark "hardwall" device as non-seekableChris Metcalf1-1/+1
Arnd's recent patch series tagged this device with noop_llseek, conservatively. In fact, it should be no_llseek, which we arrange for by opening the device with nonseekable_open(). Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
2010-11-01asm-generic/stat.h: support 64-bit file time_t for stat()Chris Metcalf3-5/+9
The existing asm-generic/stat.h specifies st_mtime, etc., as a 32-value, and works well for 32-bit architectures (currently microblaze, score, and 32-bit tile). However, for 64-bit architectures it isn't sufficient to return 32 bits of time_t; this isn't good insurance against the 2037 rollover. (It also makes glibc support less convenient, since we can't use glibc's handy STAT_IS_KERNEL_STAT mode.) This change extends the two "timespec" fields for each of the three atime, mtime, and ctime fields from "int" to "long". As a result, on 32-bit platforms nothing changes, and 64-bit platforms will now work as expected. The only wrinkle is 32-bit userspace under 64-bit kernels taking advantage of COMPAT mode. For these, we leave the "struct stat64" definitions with the "int" versions of the time_t and nsec fields, so that architectures can implement compat_sys_stat64() and friends with sys_stat64(), etc., and get the expected 32-bit structure layout. This requires a field-by-field copy in the kernel, implemented by the code guarded under __ARCH_WANT_STAT64. This does mean that the shape of the "struct stat" and "struct stat64" structures is different on a 64-bit kernel, but only one of the two structures should ever be used by any given process: "struct stat" is meant for 64-bit userspace only, and "struct stat64" for 32-bit userspace only. (On a 32-bit kernel the two structures continue to have the same shape, since "long" is 32 bits.) The alternative is keeping the two structures the same shape on 64-bit kernels, which means a 64-bit time_t in "struct stat64" for 32-bit processes. This is a little unnatural since 32-bit userspace can't do anything with 64 bits of time_t information, since time_t is just "long", not "int64_t"; and in any case 32-bit userspace might expect to be running under a 32-bit kernel, which can't provide the high 32 bits anyway. In the case of a 32-bit kernel we'd then be extending the kernel's 32-bit time_t to 64 bits, then truncating it back to 32 bits again in userspace, for no particular reason. And, as mentioned above, if we have 64-bit time_t for 32-bit processes we can't easily use glibc's STAT_IS_KERNEL_STAT, since glibc's stat structure requires an embedded "struct timespec", which is a pair of "long" (32-bit) values in a 32-bit userspace. "Inventive" solutions are possible, but are pretty hacky. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com> Acked-by: Arnd Bergmann <arnd@arndb.de>
2010-11-01arch/tile: don't allow user code to set the PL via ptrace or signal returnChris Metcalf2-18/+24
The kernel was allowing any component of the pt_regs to be updated either by signal handlers writing to the stack, or by processes writing via PTRACE_POKEUSR or PTRACE_SETREGS, which meant they could set their PL up from 0 to 1 and get access to kernel code and data (or, in practice, cause a kernel panic). We now always reset the ex1 field, allowing the user to set their ICS bit only. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
2010-11-01arch/tile: correct double syscall restart for nested signalsChris Metcalf1-1/+5
This change is modelled on similar fixes for other architectures. The pt_regs "faultnum" member is set to the trap (fault) number that caused us to enter the kernel, and is INT_SWINT_1 for the syscall software interrupt. We already supported a pseudo value, INT_SWINT_1_SIGRETURN, that we used for the rt_sigreturn syscall; it avoided the case where one signal was handled, then we "tail-called" to another handler. This change avoids the similar case where we start to call one handler, then are preempted into another handler when we start trying to run the first handler. We clear ->faultnum after calling handle_signal(), and to be paranoid also in the case where there was no signal to deliver. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
2010-11-01arch/tile: avoid __must_check warning on one strict_strtol checkChris Metcalf1-2/+6
For the "initfree" boot argument it's not that big a deal, but to avoid warnings in the code, we check for a valid value before allowing the specified argument to override the kernel default. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>

2010-11-01arch/tile: complete migration to new kmap_atomic schemeChris Metcalf7-24/+40
This change makes KM_TYPE_NR independent of the actual deprecated list of km_type values, which are no longer used in tile code anywhere. For now we leave it set to 8, allowing that many nested mappings, and thus reserving 32MB of address space. A few remaining places using KM_* values were cleaned up as well.

2010-11-01ARM: mach-shmobile: include drivers/sh/KconfigPaul Mundt1-0/+2

2010-10-30ARM: h1940: Fix backlight and LCD power functionsVasily Khoruzhick2-16/+66
Current implementation of LCD and backlight power control functions is not complete, as result PDA consumes power in suspend. Fix this issue by managing state of some latch bits, just like WinMobile does. Signed-off-by: Vasily Khoruzhick <anarsoul@gmail.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-10-29x86, alternative: Call stop_machine_text_poke() on all cpusJason Baron1-1/+1
Currently, text_poke_smp() passes a NULL as the third argument to __stop_machine(), which will only run stop_machine_text_poke() on 1 cpu. Change NULL -> cpu_online_mask, as stop_machine_text_poke() is intended to be run on all cpus. I actually didn't notice any problems with stop_machine_text_poke() only being called on 1 cpu, but found this via code inspection.

2010-10-30ARM: S3C2440: fix boot failure introduced by recent changes in gpiolibAbdoulaye Walsimou Gaye1-0/+2
Recent changes in s3c gpio break mini2440 board and may be others. The problem is that mach-mini2440.c: mini2440_init() (where we call s3c_gpio_setpull()) is called before s3c2440.c: s3c2440_init() (where we initialize s3c24xx_gpiocfg_default.set_pull function pointer). This causes dereferencing of NULL pointer at boot time and a kernel panic.
