      Input: do not use property bits when generating module alias · 09c3e01b
      Dmitry Torokhov authored
      The commit 8724ecb0 ("Input: allow matching device IDs on property
      bits") started using property bits when generating module aliases for input
      handlers, but did not adjust the generation of MODALIAS attribute on input
      device uevents, breaking automatic module loading. Given that no handler
      currently uses property bits in their module tables, let's revert this part
      of the commit for now.

      stmmac: Don't access tx_q->dirty_tx before netif_tx_lock · 8d5f4b07
      Bernd Edlinger authored
      This is the possible reason for different hard to reproduce
      problems on my ARMv7-SMP test system.
      
      The symptoms are in recent kernels imprecise external aborts,
      and in older kernels various kinds of network stalls and
      unexpected page allocation failures.
      
      My testing indicates that the trouble started between v4.5 and v4.6
      and prevails up to v4.14.
      
      Using the dirty_tx before acquiring the spin lock is clearly
      wrong and was first introduced with v4.6.

      ipv6: flowlabel: do not leave opt->tot_len with garbage · 864e2a1f
      Eric Dumazet authored
      When syzkaller team brought us a C repro for the crash [1] that
      had been reported many times in the past, I finally could find
      the root cause.
      
      If FlowLabel info is merged by fl6_merge_options(), we leave
      part of the opt_space storage provided by udp/raw/l2tp with random value
      in opt_space.tot_len, unless a control message was provided at sendmsg()
      time.
      
      Then ip6_setup_cork() would use this random value to perform a kzalloc()
      call. Undefined behavior and crashes.
      
      Fix is to properly set tot_len in fl6_merge_options()
      
      At the same time, we can also avoid consuming memory and cpu cycles
      to clear it, if every option is copied via a kmemdup(). This is the
      change in ip6_setup_cork().

      of_mdio: Fix broken PHY IRQ in case of probe deferral · 66bdede4
      Geert Uytterhoeven authored
      If an Ethernet PHY is initialized before the interrupt controller it is
      connected to, a message like the following is printed:
      
          irq: no irq domain found for /interrupt-controller@e61c0000 !
      
      However, the actual error is ignored, leading to a non-functional (POLL)
      PHY interrupt later:
      
          Micrel KSZ8041RNLI ee700000.ethernet-ffffffff:01: attached PHY driver [Micrel KSZ8041RNLI] (mii_bus:phy_addr=ee700000.ethernet-ffffffff:01, irq=POLL)
      
      Depending on whether the PHY driver will fall back to polling, Ethernet
      may or may not work.
      
      To fix this:
        1. Switch of_mdiobus_register_phy() from irq_of_parse_and_map() to
           of_irq_get().
           Unlike the former, the latter returns -EPROBE_DEFER if the
           interrupt controller is not yet available, so this condition can be
           detected.
           Other errors are handled the same as before, i.e. use the passed
           mdio->irq[addr] as interrupt.
        2. Propagate and handle errors from of_mdiobus_register_phy() and
           of_mdiobus_register_device().

      mlxsw: spectrum: Configure TTL of "inherit" for offloaded tunnels
      
      Petr says:
      
      Currently mlxsw only offloads tunnels that are configured with TTL of "inherit"
      (which is the default). However, Spectrum defaults to 255 and the driver
      neglects to change the configuration. Thus the tunnel packets from offloaded
      tunnels always have TTL of 255, even though tunnels with explicit TTL of 255 are
      never actually offloaded.
      
      To fix this, introduce support for TIGCR, the register that keeps the related
      bits of global tunnel configuration, and use it on first offload to properly
      configure inheritance of TTL of tunnel packets from overlay packets.

      There are two initialization paths for the sock_reuseport structure in a
      socket: Through the udp/tcp bind paths of SO_REUSEPORT sockets or through
      SO_ATTACH_REUSEPORT_[CE]BPF before bind.  The existing implementation
      assumedthat the socket lock protected both of these paths when it actually
      only protects the SO_ATTACH_REUSEPORT path.  Syzkaller triggered this
      double allocation by running these paths concurrently.
      
      This patch moves the check for double allocation into the reuseport_alloc
      function which is protected by a global spin lock.

      sock: correct sk_wmem_queued accounting on efault in tcp zerocopy · 54d43117
      Willem de Bruijn authored
      Syzkaller hits WARN_ON(sk->sk_wmem_queued) in sk_stream_kill_queues
      after triggering an EFAULT in __zerocopy_sg_from_iter.
      
      On this error, skb_zerocopy_stream_iter resets the skb to its state
      before the operation with __pskb_trim. It cannot kfree_skb like
      datagram callers, as the skb may have data from a previous send call.
      
      __pskb_trim calls skb_condense for unowned skbs, which adjusts their
      truesize. These tcp skbuffs are owned and their truesize must add up
      to sk_wmem_queued. But they match because their skb->sk is NULL until
      tcp_transmit_skb.
      
      Temporarily set skb->sk when calling __pskb_trim to signal that the
      skbuffs are owned and avoid the skb_condense path.

      that the verifier matches on.
      
      They are targeted for net tree, note that once net gets merged

      signature change of the function find_good_pkt_pointers() as
      well as data_meta patterns present in net-next tree. You can
