      i40e: Fix bug with TCP over IPv6 over VXLAN · df23075f
      Anjali Singhai authored
      The driver was examining the outer protocol layer to set the inner protocol
      layer checksum offload.  In the case of TCP over IPV6 over an IPv4 based
      VXLAN the inner checksum offloads would be set to look for IPv4/UDP instead
      of IPv6/TCP.  This code fixes that so that the driver will look at the
      proper layer for encapsulation offload settings.

      i40e: fix un-necessary Tx hangs · d91649f5
      Jesse Brandeburg authored
      When the driver was polling with interrupts disabled the hardware
      will occasionally not write back descriptors.  This patch causes
      the driver to detect this situation and force an interrupt to
      fire which will flush the stuck descriptor.  Does not conflict
      with napi because if we are already polling the napi_schedule is
      ignored.  Additionally the extra interrupts are rate limited, so
      don't cause a burden to the CPU.

      subscription bitmask is used. Existing userspace code code may request
      to listen to all of the existing netlink groups by setting an all to one
      subscription group bitmask. Netlink already validates subscription via

      netfilter: conntrack: fix race between confirmation and flush · 8ca3f5e9
      Pablo Neira Ayuso authored
      Commit 5195c14c ("netfilter: conntrack: fix race in
      __nf_conntrack_confirm against get_next_corpse") aimed to resolve the
      race condition between the confirmation (packet path) and the flush
      command (from control plane). However, it introduced a crash when
      several packets race to add a new conntrack, which seems easier to
      reproduce when nf_queue is in place.
      
      Fix this race, in __nf_conntrack_confirm(), by removing the CT
      from unconfirmed list before checking the DYING bit. In case
      race occured, re-add the CT to the dying list
      
      This patch also changes the verdict from NF_ACCEPT to NF_DROP when
      we lose race. Basically, the confirmation happens for the first packet
      that we see in a flow. If you just invoked conntrack -F once (which
      should be the common case), then this is likely to be the first packet
      of the flow (unless you already called flush anytime soon in the past).
      This should be hard to trigger, but better drop this packet, otherwise
      we leave things in inconsistent state since the destination will likely
      reply to this packet, but it will find no conntrack, unless the origin
      retransmits.
      
      The change of the verdict has been discussed in:

      mm: propagate error from stack expansion even for guard page · fee7e49d
      Linus Torvalds authored
      Jay Foad reports that the address sanitizer test (asan) sometimes gets
      confused by a stack pointer that ends up being outside the stack vma
      that is reported by /proc/maps.
      
      This happens due to an interaction between RLIMIT_STACK and the guard
      page: when we do the guard page check, we ignore the potential error
      from the stack expansion, which effectively results in a missing guard
      page, since the expected stack expansion won't have been done.
      
      And since /proc/maps explicitly ignores the guard page (commit
      d7824370: "mm: fix up some user-visible effects of the stack guard
      page"), the stack pointer ends up being outside the reported stack area.
      
      This is the minimal patch: it just propagates the error.  It also
      effectively makes the guard page part of the stack limit, which in turn
      measn that the actual real stack is one page less than the stack limit.
      
      Let's see if anybody notices.  We could teach acct_stack_growth() to
      allow an extra page for a grow-up/grow-down stack in the rlimit test,
      but I don't want to add more complexity if it isn't needed.
