      vxlan: Fix kernel crash on rmmod. · f89e57c4
      Pravin B Shelar authored
      
      
      vxlan exit module unregisters vxlan net and then it unregisters
      rtnl ops which triggers vxlan_dellink() from __rtnl_kill_links().
      vxlan_dellink() deletes vxlan-dev from vxlan_list which has
      list-head in vxlan-net-struct but that is already gone due to
      net-unregister. That is how we are getting following crash.
      
      Following commit fixes the crash by fixing module exit path.

      ipv6: in case of link failure remove route directly instead of letting it expire · 1eb4f758
      Hannes Frederic Sowa authored
      
      
      We could end up expiring a route which is part of an ecmp route set. Doing
      so would invalidate the rt->rt6i_nsiblings calculations and could provoke
      the following panic:

      macvtap: correctly linearize skb when zerocopy is used · 61d46bf9
      Jason Wang authored
      Userspace may produce vectors greater than MAX_SKB_FRAGS. When we try to
      linearize parts of the skb to let the rest of iov to be fit in
      the frags, we need count copylen into linear when calling macvtap_alloc_skb()
      instead of partly counting it into data_len. Since this breaks
      zerocopy_sg_from_iovec() since its inner counter assumes nr_frags should
      be zero at beginning. This cause nr_frags to be increased wrongly without
      setting the correct frags.
      
      This bug were introduced from b92946e2

      According to the commit 16b0dc29
      
      
      (dummy: fix rcu_sched self-detected stalls)
      
      Eric Dumazet fix the problem in dummy, but the ifb will occur the
      same problem like the dummy modules.
      
      Trying to "modprobe ifb numifbs=30000" triggers :
      
      INFO: rcu_sched self-detected stall on CPU
      
      After this splat, RTNL is locked and reboot is needed.
      
      We must call cond_resched() to avoid this, even holding RTNL.

      Michal Simek authored
      
      
      The reason is that other applications like strace
      think that every __NR_xx is syscall.
      Also __NR_syscalls is not used by user applications/libs.

      Pull networking updates from David Miller:
       "This is a re-do of the net-next pull request for the current merge
        window.  The only difference from the one I made the other day is that
        this has Eliezer's interface renames and the timeout handling changes
        made based upon your feedback, as well as a few bug fixes that have
        trickeled in.
      
        Highlights:
      
         1) Low latency device polling, eliminating the cost of interrupt
            handling and context switches.  Allows direct polling of a network
            device from socket operations, such as recvmsg() and poll().
      
            Currently ixgbe, mlx4, and bnx2x support this feature.
      
            Full high level description, performance numbers, and design in
            commit 0a4db187 ("Merge branch 'll_poll'")
      
            From Eliezer Tamir.
      
         2) With the routing cache removed, ip_check_mc_rcu() gets exercised
            more than ever before in the case where we have lots of multicast
            addresses.  Use a hash table instead of a simple linked list, from
            Eric Dumazet.
      
         3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from
            Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski,
            Marek Puzyniak, Michal Kazior, and Sujith Manoharan.
      
         4) Support reporting the TUN device persist flag to userspace, from
            Pavel Emelyanov.
      
         5) Allow controlling network device VF link state using netlink, from
            Rony Efraim.
      
         6) Support GRE tunneling in openvswitch, from Pravin B Shelar.
      
         7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from
            Daniel Borkmann and Eric Dumazet.
      
         8) Allow controlling of TCP quickack behavior on a per-route basis,
            from Cong Wang.
      
         9) Several bug fixes and improvements to vxlan from Stephen
            Hemminger, Pravin B Shelar, and Mike Rapoport.  In particular,
            support receiving on multiple UDP ports.
      
        10) Major cleanups, particular in the area of debugging and cookie
            lifetime handline, to the SCTP protocol code.  From Daniel
            Borkmann.
      
        11) Allow packets to cross network namespaces when traversing tunnel
            devices.  From Nicolas Dichtel.
      
        12) Allow monitoring netlink traffic via AF_PACKET sockets, in a
            manner akin to how we monitor real network traffic via ptype_all.
            From Daniel Borkmann.
      
        13) Several bug fixes and improvements for the new alx device driver,
            from Johannes Berg.
      
        14) Fix scalability issues in the netem packet scheduler's time queue,
            by using an rbtree.  From Eric Dumazet.
      
        15) Several bug fixes in TCP loss recovery handling, from Yuchung
            Cheng.
      
        16) Add support for GSO segmentation of MPLS packets, from Simon
            Horman.
      
        17) Make network notifiers have a real data type for the opaque
            pointer that's passed into them.  Use this to properly handle
            network device flag changes in arp_netdev_event().  From Jiri
            Pirko and Timo Teräs.
      
        18) Convert several drivers over to module_pci_driver(), from Peter
            Huewe.
      
        19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a
            O(1) calculation instead.  From Eric Dumazet.
      
        20) Support setting of explicit tunnel peer addresses in ipv6, just
            like ipv4.  From Nicolas Dichtel.
      
        21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet.
      
        22) Prevent a single high rate flow from overruning an individual cpu
            during RX packet processing via selective flow shedding.  From
            Willem de Bruijn.
      
        23) Don't use spinlocks in TCP md5 signing fast paths, from Eric
            Dumazet.
      
        24) Don't just drop GSO packets which are above the TBF scheduler's
            burst limit, chop them up so they are in-bounds instead.  Also
            from Eric Dumazet.
      
        25) VLAN offloads are missed when configured on top of a bridge, fix
            from Vlad Yasevich.
      
        26) Support IPV6 in ping sockets.  From Lorenzo Colitti.
      
        27) Receive flow steering targets should be updated at poll() time
            too, from David Majnemer.
      
        28) Fix several corner case regressions in PMTU/redirect handling due
            to the routing cache removal, from Timo Teräs.
      
        29) We have to be mindful of ipv4 mapped ipv6 sockets in
            upd_v6_push_pending_frames().  From Hannes Frederic Sowa.
      
        30) Fix L2TP sequence number handling bugs, from James Chapman."

      Pull drm updates from Dave Airlie:
       "Okay this is the big one, I was stalled on the fbdev pull req as I
        stupidly let fbdev guys merge a patch I required to fix a warning with
        some patches I had, they ended up merging the patch from the wrong
        place, but the warning should be fixed.  In future I'll just take the
        patch myself!
      
        Outside drm:
      
        There are some snd changes for the HDMI audio interactions on haswell,
        they've been acked for inclusion via my tree.  This relies on the
        wound/wait tree from Ingo which is already merged.
      
        Major changes:
      
        AMD finally released the dynamic power management code for all their
        GPUs from r600->present day, this is great, off by default for now but
        also a huge amount of code, in fact it is most of this pull request.
      
        Since it landed there has been a lot of community testing and Alex has
        sent a lot of fixes for any bugs found so far.  I suspect radeon might
        now be the biggest kernel driver ever :-P p.s.  radeon.dpm=1 to enable
        dynamic powermanagement for anyone.
      
        New drivers:
      
        Renesas r-car display unit.
      
        Other highlights:
      
         - core: GEM CMA prime support, use new w/w mutexs for TTM
           reservations, cursor hotspot, doc updates
         - dvo chips: chrontel 7010B support
         - i915: Haswell (fbc, ips, vecs, watermarks, audio powerwell),
           Valleyview (enabled by default, rc6), lots of pll reworking, 30bpp
           support (this time for sure)
         - nouveau: async buffer object deletion, context/register init
           updates, kernel vp2 engine support, GF117 support, GK110 accel
           support (with external nvidia ucode), context cleanups.
         - exynos: memory leak fixes, Add S3C64XX SoC series support, device
           tree updates, common clock framework support,
         - qxl: cursor hotspot support, multi-monitor support, suspend/resume
           support
         - mgag200: hw cursor support, g200 mode limiting
         - shmobile: prime support
         - tegra: fixes mostly
      
        I've been banging on this quite a lot due to the size of it, and it
        seems to okay on everything I've tested it on."

      Reason for this crash is a gcc miscompilation in the fault handlers of
      pa_memcpy() which return the fault address instead of the copied bytes.
      Since this seems to be a generic problem with gcc-4.7.x (and below), it's
      better to simplify the fault handlers in pa_memcpy to avoid this problem.
      
      Here is a simple reproducer for the problem:
      
      int main(int argc, char **argv)
      {
      	int fd, nbytes;
      	struct iovec wr_iovec[] = {
      		{ "TEST STRING                     ",32},
      		{ (char*)0x40005000,32} }; // random memory.
      	fd = open(DATA_FILE, O_RDWR | O_CREAT, 0666);
      	nbytes = writev(fd, wr_iovec, 2);
      	printf("return value = %d, errno %d (%s)\n",
      		nbytes, errno, strerror(errno));
      	return 0;
      }

      There is no gcc PR as pa_memcpy is not legitimate C code. There is an
      implicit assumption that certain variables will contain correct values
      when an exception occurs and the code randomly jumps to one of the
      exception blocks.  There is no guarantee of this.  If a PR was filed, it
      would likely be marked as invalid.

      parisc: Ensure volatile space register %sr1 is not clobbered · e8d8fc21
      John David Anglin authored
      
      
      I still see the occasional random segv on rp3440.  Looking at one of
      these (a code 15), it appeared the problem must be with the cache
      handling of anonymous pages.  Reviewing this, I noticed that the space
      register %sr1 might be being clobbered when we flush an anonymous page.
      
      Register %sr1 is used for TLB purges in a couple of places.  These
      purges are needed on PA8800 and PA8900 processors to ensure cache
      consistency of flushed cache lines.
      
      The solution here is simply to move the %sr1 load into the TLB lock
      region needed to ensure that one purge executes at a time on SMP
      systems.  This was already the case for one use.  After a few days of
      operation, I haven't had a random segv on my rp3440.

      If the value which should be moved into a space register is zero, we can
      optimize the inline assembly to become "mtsp %r0,%srX".

      parisc: switch to gzip-compressed vmlinuz kernel · 594174d8
      Helge Deller authored
      The latest PA-RISC Boot Loader (palo) allows loading of gzip compressed
      vmlinuz kernels. So let's now switch to build a vmlinuz file when we
      build a palo boot image.
      
      PALO version 1.9 (or higher) is required for this which is available at
      git://git.kernel.org/pub/scm/linux/kernel/git/deller/palo.git

      parisc: fix LMMIO mismatch between PAT length and MASK register · dac76f1b
      Helge Deller authored
      
      
      The LMMIO length reported by PAT and the length given by the LBA MASK
      register are not consistent. This leads e.g. to a not-working ATI FireGL
      card with the radeon DRM driver since the memory can't be mapped.
      
      Fix this by correctly adjusting the resource sizes.

      drivers/net: caif: fix wrong rtnl_is_locked() usage · 56e0ef52
      Konstantin Khlebnikov authored
      
      
      rtnl_is_locked() doesn't check who holds this lock, it just tells that it's
      locked right now. if caif::ldisc_close really can be called under rtrnl_lock
      then it should release net device in other context because there is no way
      to grab rtnl_lock without deadlock.
      
      This patch adds work which releases these devices. Also this patch fixes calling
      dev_close/unregister_netdevice without rtnl_lock from caif_ser_exit().
