2013-11-03ipc, msg: forbid negative values for "msg{max,mnb,mni}"Mathias Krause1-3/+3
Negative message lengths make no sense -- so don't do negative queue lenghts or identifier counts. Prevent them from getting negative. Also change the underlying data types to be unsigned to avoid hairy surprises with sign extensions in cases where those variables get evaluated in unsigned expressions with bigger data types, e.g size_t. In case a user still wants to have "unlimited" sizes she could just use INT_MAX instead.

2013-10-30percpu: fix this_cpu_sub() subtrahend casting for unsignedsGreg Thelen1-4/+4
this_cpu_sub() is implemented as negation and addition. This patch casts the adjustment to the counter type before negation to sign extend the adjustment. This helps in cases where the counter type is wider than an unsigned adjustment. An alternative to this patch is to declare such operations unsupported, but it seemed useful to avoid surprises. This patch specifically helps the following example: unsigned int delta = 1 preempt_disable() this_cpu_write(long_counter, 0) this_cpu_sub(long_counter, delta) preempt_enable() Before this change long_counter on a 64 bit machine ends with value 0xffffffff, rather than 0xffffffffffffffff. This is because this_cpu_sub(pcp, delta) boils down to this_cpu_add(pcp, -delta), which is basically: long_counter = 0 + 0xffffffff Also apply the same cast to: __this_cpu_sub() __this_cpu_sub_return() this_cpu_sub_return() All percpu_test.ko passes, especially the following cases which previously failed: l -= ui_one; __this_cpu_sub(long_counter, ui_one); CHECK(l, long_counter, -1); l -= ui_one; this_cpu_sub(long_counter, ui_one); CHECK(l, long_counter, -1); CHECK(l, long_counter, 0xffffffffffffffff); ul -= ui_one; __this_cpu_sub(ulong_counter, ui_one); CHECK(ul, ulong_counter, -1); CHECK(ul, ulong_counter, 0xffffffffffffffff); ul = this_cpu_sub_return(ulong_counter, ui_one); CHECK(ul, ulong_counter, 2); ul = __this_cpu_sub_return(ulong_counter, ui_one); CHECK(ul, ulong_counter, 1); Signed-off-by: Greg Thelen <gthelen@google.com> Acked-by: Tejun Heo <tj@kernel.org> Acked-by: Johannes Weiner <hannes@cmpxchg.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2013-10-29uprobes: Teach uprobe_copy_process() to handle CLONE_VFORKOleg Nesterov1-2/+2
uprobe_copy_process() does nothing if the child shares ->mm with the forking process, but there is a special case: CLONE_VFORK. In this case it would be more correct to do dup_utask() but avoid dup_xol(). This is not that important, the child should not unwind its stack too much, this can corrupt the parent's stack, but at least we need this to allow to ret-probe __vfork() itself. Note: in theory, it would be better to check task_pt_regs(p)->sp instead of CLONE_VFORK, we need to dup_utask() if and only if the child can return from the function called by the parent. But this needs the arch-dependant helper, and I think that nobody actually does clone(same_stack, CLONE_VM).

2013-10-29uprobes: Remove the wrong __weak attributeRalf Baechle1-1/+1
linux/uprobes.h declares arch_uprobe_skip_sstep() as a weak function. But as there is no definition of generic version so when trying to build uprobes for an architecture that doesn't yet have a arch_uprobe_skip_sstep() implementation, the vmlinux will try to call arch_uprobe_skip_sstep() somehwere in Stupidhistan leading to a system crash. We rather want a proper link error so remove arch_uprobe_skip_sstep(). Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Oleg Nesterov <oleg@redhat.com>
2013-10-29perf: Fix perf ring buffer memory orderingPeter Zijlstra1-5/+7
The PPC64 people noticed a missing memory barrier and crufty old comments in the perf ring buffer code. So update all the comments and add the missing barrier. When the architecture implements local_t using atomic_long_t there will be double barriers issued; but short of introducing more conditional barrier primitives this is the best we can do.

In v3.9 6fd6ce2056de2709 ("ipv6: Do not depend on rt->n in ip6_finish_output2()." changed the behaviour of ip6_finish_output2() such that the recently introduced rt6_nexthop() is used instead of an assigned neighbor. As rt6_nexthop() prefers rt6i_gateway only for gatewayed routes this causes a problem for users like IPVS, xt_TEE and RAW(hdrincl) if they want to use different address for routing compared to the destination address. Another case is when redirect can create RTF_DYNAMIC route without RTF_GATEWAY flag, we ignore the rt6i_gateway in rt6_nexthop(). Fix the above problems by considering the rt6i_gateway if present, so that traffic routed to address on local subnet is not wrongly diverted to the destination address.

Commit 3fa4d734 (usb: phy: rename nop_usb_xceiv => usb_phy_gen_xceiv) changed the conditional around the declaration of usb_nop_xceiv_register from #if defined(CONFIG_NOP_USB_XCEIV) || (defined(CONFIG_NOP_USB_XCEIV_MODULE) && defined(MODULE)) to #if IS_ENABLED(CONFIG_NOP_USB_XCEIV) While that looks the same, it is semantically different. The first expression is true if CONFIG_NOP_USB_XCEIV is built as module and if the including code is built as module. The second expression is true if code depending on CONFIG_NOP_USB_XCEIV if built as module or into the kernel.

2013-10-16mm: memcg: handle non-error OOM situations more gracefullyJohannes Weiner2-43/+14
Commit 3812c8c8f395 ("mm: memcg: do not trap chargers with full callstack on OOM") assumed that only a few places that can trigger a memcg OOM situation do not return VM_FAULT_OOM, like optional page cache readahead. But there are many more and it's impractical to annotate them all. First of all, we don't want to invoke the OOM killer when the failed allocation is gracefully handled, so defer the actual kill to the end of the fault handling as well. This simplifies the code quite a bit for added bonus. Second, since a failed allocation might not be the abrupt end of the fault, the memcg OOM handler needs to be re-entrant until the fault finishes for subsequent allocation attempts. If an allocation is attempted after the task already OOMed, allow it to bypass the limit so that it can quickly finish the fault and invoke the OOM killer.

Some USB drive enclosures do not correctly report an overflow condition if they hold a drive with a capacity over 2TB and are confronted with a READ_CAPACITY_10. They answer with their capacity modulo 2TB. The generic layer cannot cope with that. It must be told to use READ_CAPACITY_16 from the beginning.

It seems Intel hw designers decided that was too nice a facility to allow us to have so they removed it when they went on-die (so since Ironlake at least). Now Alex Williamson added support for VGA arbitration for newer GPUs however this now exposes itself to userspace as requireing arbitration of GPU VGA regions and the X server gets involved and disables things that it can't handle when VGA access is possibly required around every operation. So in order to not break userspace we just reverted things back to the old known broken status so maybe we can try and design out way out.

2013-10-11Revert "i915: Update VGA arbiter support for newer devices"Dave Airlie1-7/+0
This reverts commit 81b5c7bc8de3e6f63419139c2fc91bf81dea8a7d. Adding drm/i915 into the vga arbiter chain means that X (in a piece of well-meant paranoia) will do a get/put on the vga decoding around _every_ accel call down into the ddx. Which results in some nice performance disasters [1]. This really breaks userspace, by disabling DRI for everyone, and stops OpenGL from working, this isn't limited to just the i915 but both the integrated and discrete GPUs on multi-gpu systems, in other words this causes untold worlds of pain, Ville tried to come up with a Great Hack to fiddle the required VGA I/O ops behind everyone's back using stop_machine, but that didn't really work out [2]. Given that we're fairly late in the -rc stage for such games let's just revert this all. One thing we might want to keep is to delay the disabling of the vga decoding until the fbdev emulation and the fbcon screen is set up. If we kill vga mem decoding beforehand fbcon can end up with a white square in the top-left corner it tried to save from the vga memory for a seamless transition. And we have bug reports on older platforms which seem to match these symptoms. But again that's something to play around with in -next.

Allow architectures which have a disabled get_cycles() function to provide a random_get_entropy() function which provides a fine-grained, rapidly changing counter that can be used by the /dev/random driver. For example, an architecture might have a rapidly changing register used to control random TLB cache eviction, or DRAM refresh that doesn't meet the requirements of get_cycles(), but which is good enough for the needs of the random driver.
