      net: bcmgenet: fix error returns in bcmgenet_probe() · 24a63fe6
      Zhang Changzhong authored
      The driver forgets to call clk_disable_unprepare() in error path after
      a success calling for clk_prepare_enable().
      
      Fix to goto err_clk_disable if clk_prepare_enable() is successful.
      
      Fixes: 99d55638 ("net: bcmgenet: enable NETIF_F_HIGHDMA flag")

      net: ieee802154: adf7242: Replace HTTP links with HTTPS ones · 19dc3654
      Alexander A. Klimov authored
      Rationale:
      Reduces attack surface on kernel devs opening the links for MITM
      as HTTPS traffic is much harder to manipulate.
      
      Deterministic algorithm:
      For each file:
        If not .svg:
          For each line:
            If doesn't contain `\bxmlns\b`:
              For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
      	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
                  If both the HTTP and HTTPS versions
                  return 200 OK and serve the same content:
                    Replace HTTP with HTTPS.

      bonding: check error value of register_netdevice() immediately · 544f287b
      Taehee Yoo authored
      If register_netdevice() is failed, net_device should not be used
      because variables are uninitialized or freed.
      So, the routine should be stopped immediately.
      But, bond_create() doesn't check return value of register_netdevice()
      immediately. That will result in a panic because of using uninitialized
      or freed memory.
      
      Test commands:
          modprobe netdev-notifier-error-inject
          echo -22 > /sys/kernel/debug/notifier-error-inject/netdev/\
      actions/NETDEV_REGISTER/error
          modprobe bonding max_bonds=3
      
      Splat looks like:

      arm64: dts: clearfog-gt-8k: fix switch link configuration · 7c6719a1
      Russell King authored
      The commit below caused a regression for clearfog-gt-8k, where the link
      between the switch and the host does not come up.
      
      Investigation revealed two issues:
      - MV88E6xxx DSA no longer allows an in-band link to come up as the link
        is programmed to be forced down. Commit "net: dsa: mv88e6xxx: fix
        in-band AN link establishment" addresses this.
      
      - The dts configured dissimilar link modes at each end of the host to
        switch link; the host was configured using a fixed link (so has no
        in-band status) and the switch was configured to expect in-band
        status.
      
      With both issues fixed, the regression is resolved.
      
      Fixes: 34b5e6a3 ("net: dsa: mv88e6xxx: Configure MAC when using fixed link")
