2013-06-26ipv6: rearm router solicitaion timer when setting new tokenized addressHannes Frederic Sowa
When a new tokenized address gets installed we send out just one router solicition. We should send out `rtr_solicits' in case one router advertisment got lost. So, rearm the timer as we do in addrconf_dad_complete.

2013-06-26ipv6: ip6_sk_dst_check() must not assume ipv6 dstEric Dumazet
It's possible to use AF_INET6 sockets and to connect to an IPv4 destination. After this, socket dst cache is a pointer to a rtable, not rt6_info. ip6_sk_dst_check() should check the socket dst cache is IPv6, or else various corruptions/crashes can happen.

2013-06-26net: fix kernel deadlock with interface rename and netdev name retrieval.Nicolas Schichan
When the kernel (compiled with CONFIG_PREEMPT=n) is performing the rename of a network interface, it can end up waiting for a workqueue to complete. If userland is able to invoke a SIOCGIFNAME ioctl or a SO_BINDTODEVICE getsockopt in between, the kernel will deadlock due to the fact that read_secklock_begin() will spin forever waiting for the writer process (the one doing the interface rename) to update the devnet_rename_seq sequence. This patch fixes the problem by adding a helper (netdev_get_name()) and using it in the code handling the SIOCGIFNAME ioctl and SO_BINDTODEVICE setsockopt. The netdev_get_name() helper uses raw_seqcount_begin() to avoid spinning forever, waiting for devnet_rename_seq->sequence to become even. cond_resched() is used in the contended case, before retrying the access to give the writer process a chance to finish. The use of raw_seqcount_begin() will incur some unneeded work in the reader process in the contended case, but this is better than deadlocking the system.

2013-06-26perf/x86: Fix shared register mutual exclusion enforcementStephane Eranian
This patch fixes a problem with the shared registers mutual exclusion code and incremental event scheduling by the generic perf_event code. There was a bug whereby the mutual exclusion on the shared registers was not enforced because of incremental scheduling abort due to event constraints. As an example on Intel Nehalem, consider the following events: group1= L1D_CACHE_LD:E_STATE,OFFCORE_RESPONSE_0:PF_RFO,L1D_CACHE_LD:I_STATE group2= L1D_CACHE_LD:I_STATE The L1D_CACHE_LD event can only be measured by 2 counters. Yet, there are 3 instances here. The first group can be scheduled and is committed. Then, the generic code tries to schedule group2 and this fails (because there is no more counter to support the 3rd instance of L1D_CACHE_LD). But in x86_schedule_events() error path, put_event_contraints() is invoked on ALL the events and not just the ones that just failed. That causes the "lock" on the shared offcore_response MSR to be released. Yet the first group is actually scheduled and is exposed to reprogramming of that shared msr by the sibling HT thread. In other words, there is no guarantee on what is measured. This patch fixes the problem by tagging committed events with the PERF_X86_EVENT_COMMITTED tag. In the error path of x86_schedule_events(), only the events NOT tagged have their constraint released. The tag is eventually removed when the event in descheduled.

Using static data for fields which are accessed by HW will fail if the driver is build as a module (since this would be vmalloc'ed memory). This Bug was revealed via "s390: remove virt_to_phys implementation" - the old virt_to_phys implementation would have translated the address but it was not guaranteed that the memory was contiguous.

2013-06-26s390/vmwatchdog: do not use static dataSebastian Ott
Using static data for fields which are accessed by HW will fail if the driver is build as a module (since this would be vmalloc'ed memory). This Bug was revealed via "s390: remove virt_to_phys implementation" - the old virt_to_phys implementation would have translated the address but it was not guaranteed that the memory was contiguous. Fix it by putting the data on the stack.
