      Add genphy_c45_config_aneg() function to phy-c45.c · 94acaeb5
      Marco Hartmann authored
      Commit 34786005 ("net: phy: prevent PHYs w/o Clause 22 regs from calling
      genphy_config_aneg") introduced a check that aborts phy_config_aneg()
      if the phy is a C45 phy.
      This causes phy_state_machine() to call phy_error() so that the phy
      ends up in PHY_HALTED state.
      
      Instead of returning -EOPNOTSUPP, call genphy_c45_config_aneg()
      (analogous to the C22 case) so that the state machine can run
      correctly.
      
      genphy_c45_config_aneg() closely resembles mv3310_config_aneg()
      in drivers/net/phy/marvell10g.c, excluding vendor specific
      configurations for 1000BaseT.

      net_sched: fix a NULL pointer deref in ipt action · 981471bd
      Cong Wang authored
      The net pointer in struct xt_tgdtor_param is not explicitly
      initialized therefore is still NULL when dereferencing it.
      So we have to find a way to pass the correct net pointer to
      ipt_destroy_target().
      
      The best way I find is just saving the net pointer inside the per
      netns struct tcf_idrinfo, which could make this patch smaller.
      
      Fixes: 0c66dc1e ("netfilter: conntrack: register hooks in netns when needed by ruleset")

      Yi-Hung Wei authored
      This patch addresses a conntrack cache issue with timeout policy.
      Currently, we do not check if the timeout extension is set properly in the
      cached conntrack entry.  Thus, after packet recirculate from conntrack
      action, the timeout policy is not applied properly.  This patch fixes the
      aforementioned issue.

      up down the nexthop_mpath_fill_node() path which is wrong for a
      blackhole.
      
      The blackhole check in nexthop_num_path is leftover from early days
      of the blackhole implementation which did not initialize the device.
      In the end the design was simpler (fewer special case checks) to set
      the device to loopback in nh_info, so the check in nexthop_num_path
      should have been removed.

      Pull x86 fixes from Thomas Gleixner:
       "A few fixes for x86:
      
         - Fix a boot regression caused by the recent bootparam sanitizing
           change, which escaped the attention of all people who reviewed that
           code.
      
         - Address a boot problem on machines with broken E820 tables caused
           by an underflow which ended up placing the trampoline start at
           physical address 0.
      
         - Handle machines which do not advertise a legacy timer of any form,
           but need calibration of the local APIC timer gracefully by making
           the calibration routine independent from the tick interrupt. Marked
           for stable as well as there seems to be quite some new laptops
           rolled out which expose this.
      
         - Clear the RDRAND CPUID bit on AMD family 15h and 16h CPUs which are
           affected by broken firmware which does not initialize RDRAND
           correctly after resume. Add a command line parameter to override
           this for machine which either do not use suspend/resume or have a
           fixed BIOS. Unfortunately there is no way to detect this on boot,
           so the only safe decision is to turn it off by default.
      
         - Prevent RFLAGS from being clobbers in CALL_NOSPEC on 32bit which
           caused fast KVM instruction emulation to break.
      
         - Explain the Intel CPU model naming convention so that the repeating
           discussions come to an end"

      ALSA: seq: Fix potential concurrent access to the deleted pool · 75545304
      Takashi Iwai authored
      The input pool of a client might be deleted via the resize ioctl, the
      the access to it should be covered by the proper locks.  Currently the
      only missing place is the call in snd_seq_ioctl_get_client_pool(), and
      this patch papers over it.
