2015-04-06ipv6: protect skb->sk accesses from recursive dereference inside the stackhannes@stressinduktion.org
We should not consult skb->sk for output decisions in xmit recursion levels > 0 in the stack. Otherwise local socket settings could influence the result of e.g. tunnel encapsulation process. ipv6 does not conform with this in three places: 1) ip6_fragment: we do consult ipv6_npinfo for frag_size 2) sk_mc_loop in ipv6 uses skb->sk and checks if we should loop the packet back to the local socket 3) ip6_skb_dst_mtu could query the settings from the user socket and force a wrong MTU Furthermore: In sk_mc_loop we could potentially land in WARN_ON(1) if we use a PF_PACKET socket ontop of an IPv6-backed vxlan device. Reuse xmit_recursion as we are currently only interested in protecting tunnel devices.

2015-04-06spi: fsl-dspi: Fix clock rate scale valuesAaron Brice
Previous algorithm had an outer loop with the values {2,3,5,7} and an inner loop with {2,4,6,8,16,32,...,32768}, and would pick the first value over the required scaling value (where the total scale was the two numbers multiplied). Since the inner loop went up to 32768 it would always pick a value of 2 for PBR and a much higher than necessary value for BR. The desired scale factor was being divided by two I believe to compensate for the much higher scale factors (the divide by two not specified in the reference manual). Updated to check all values and find the smallest scale factor possible without going over the desired clock rate.

When slowly dropping 1, 2 and then 3 fingers on an image sensor touchpad, we can see that the first finger gets reassigned a new slot while it did not move. This is due to the kernel tracking algorithm which can not assign correctly the 3 touches, being out of slots.

2015-04-06workqueue: Reorder sysfs codeFrederic Weisbecker
The sysfs code usually belongs to the botom of the file since it deals with high level objects. In the workqueue code it's misplaced and such that we'll need to work around functions references to allow the sysfs code to call APIs like apply_workqueue_attrs(). Lets move that block further in the file, almost the botom. And declare workqueue_sysfs_unregister() just before destroy_workqueue() which reference it. tj: Moved workqueue_sysfs_unregister() forward declaration where other forward declarations are.

2015-04-06x86/alternatives: Guard NOPs optimizationBorislav Petkov
Take a look at the first instruction byte before optimizing the NOP - there might be something else there already, like the ALTERNATIVE_2() in rdtsc_barrier() which NOPs out on AMD even though we just patched in an MFENCE. This happens because the alternatives sees X86_FEATURE_MFENCE_RDTSC, AMD CPUs set it, we patch in the MFENCE and right afterwards it sees X86_FEATURE_LFENCE_RDTSC which AMD CPUs don't set and we blindly optimize the NOP. Checking whether at least the first byte is 0x90 prevents that.

2015-04-06x86/asm/entry: Clear EXTRA_REGS for all executable formatsDenys Vlasenko
On failure, sys_execve() does not clobber EXTRA_REGS, so we can just return to userpsace without saving/restoring them. On success, ELF_PLAT_INIT() in sys_execve() clears all these registers. On other executable formats: - binfmt_flat.c has similar FLAT_PLAT_INIT, but x86 (and everyone else except sh) doesn't define it. - binfmt_elf_fdpic.c has ELF_FDPIC_PLAT_INIT, but x86 (and most others) doesn't define it. - There are no such hooks in binfmt_aout.c et al. We inherit EXTRA_REGS from the prior executable. This inconsistency was not intended. This change removes SAVE/RESTORE_EXTRA_REGS in stub_execve, removes register clearing in ELF_PLAT_INIT(), and instead simply clears them on success in stub_execve. Run-tested.

2015-04-06x86/signal: Remove pax argument from restore_sigcontextBrian Gerst
The 'pax' argument is unnecesary. Instead, store the RAX value directly in regs. This pattern goes all the way back to 2.1.106pre1, when restore_sigcontext() was changed to return an error code instead of EAX directly: https://git.kernel.org/cgit/linux/kernel/git/history/history.git/diff/arch/i386/kernel/signal.c?id=9a8f8b7ca3f319bd668298d447bdf32730e51174 In 2007 sigaltstack syscall support was added, where the return value of restore_sigcontext() was changed to carry the memory-copying failure code. But instead of putting 'ax' into regs->ax directly, it was carried in via a pointer and then returned, where the generic syscall return code copied it to regs->ax. So there was never any deeper reason for this suboptimal pattern, it was simply never noticed after being introduced.

2015-04-04Merge branch 'nf-hook-compress'David S. Miller
netfilter: Compress hook function signatures. Currently netfilter hooks have a function signature that is huge and has many arguments. This propagates from the hook entry points down into the individual hook implementations themselves. This means that if, for example, we want to change the type of one of these arguments then we have to touch hundreds of locations. The main initial motivation behind this is that we'd like to change the signature of "okfn" so that a socket pointer can be passed in (and reference counted properly) for the sake of using the proper socket context in the case of tunnels whilst not releasing the top level user socket from skb->sk (and thus releasing it's socket memory quota usage) in order to accomodate this. This also makes it clear who actually uses 'okfn', nf_queue(). It is absolutely critical to make this obvious because any user of 'okfn' down in these hook chains have the be strictly audited for escapability. Specifically, escapability of references to objects outside of the packet processing path. And that's exactly what nf_queue() does via it's packet reinjection framework. In fact this points out a bug in Jiri's original attempt to push the socket pointer down through netfilter's okfn. It didn't grab and drop a reference to the socket in net/netfilter/nf_queue.c as needed. Furthermore, so many code paths are simplified, and should in fact be more efficient because we aren't passing in arguments that often are simply not used by the netfilter hook at all. Further simplifications are probably possible, but this series takes care of the main cases. Unfortunately I couldn't convert ebt_do_table() because ebtables is complete and utter crap and uses ebt_do_table() outside of the hook call chains. But that should not be news to anyone.
