      net: remove MTU limits on a few ether_setup callers · 8b1efc0f
      Jarod Wilson authored
      These few drivers call ether_setup(), but have no ndo_change_mtu, and thus
      were overlooked for changes to MTU range checking behavior. They
      previously had no range checks, so for feature-parity, set their min_mtu
      to 0 and max_mtu to ETH_MAX_MTU (65535), instead of the 68 and 1500
      inherited from the ether_setup() changes. Fine-tuning can come after we get
      back to full feature-parity here.

      hv_netvsc: fix a race between netvsc_send() and netvsc_init_buf() · e8f0a89c
      Vitaly Kuznetsov authored
      Fix in commit 88098834 ("hv_netvsc: set nvdev link after populating
      chn_table") turns out to be incomplete. A crash in
      netvsc_get_next_send_section() is observed on mtu change when the device
      is under load. The race I identified is: if we get to netvsc_send() after
      we set net_device_ctx->nvdev link in netvsc_device_add() but before we
      finish netvsc_connect_vsp()->netvsc_init_buf() send_section_map is not
      allocated and we crash. Unfortunately we can't set net_device_ctx->nvdev
      link after the netvsc_init_buf() call as during the negotiation we need
      to receive packets and on the receive path we check for it. It would
      probably be possible to split nvdev into a pair of nvdev_in and nvdev_out
      links and check them accordingly in get_outbound_net_device()/
      get_inbound_net_device() but this looks like an overkill.
      
      Check that send_section_map is allocated in netvsc_send().

      ====================
      net: use core MTU range checking everywhere
      
      This stack of patches should get absolutely everything in the kernel
      converted from doing their own MTU range checking to the core MTU range
      checking. This second spin includes alterations to hopefully fix all
      concerns raised with the first, as well as including some additional
      changes to drivers and infrastructure where I completely missed necessary
      updates.
      
      These have all been built through the 0-day build infrastructure via the
      (rebasing) master branch at https://github.com/jarodwilson/linux-muck, which
      at the time of the most recent compile across 147 configs, was based on
      net-next at commit 7b1536ef.

        possible, and let the ndo_change_mtu function continue to validate any new
        MTU change requests with checks for CM or not. Note that ipoib has no

      ethernet: use net core MTU range checking in more drivers · d894be57
      Jarod Wilson authored
      Somehow, I missed a healthy number of ethernet drivers in the last pass.
      Most of these drivers either were in need of an updated max_mtu to make
      jumbo frames possible to enable again. In a few cases, also setting a
      different min_mtu to match previous lower bounds. There are also a few
      drivers that had no upper bounds checking, so they're getting a brand new
      ETH_MAX_MTU that is identical to IP_MAX_MTU, but accessible by includes
      all ethernet and ethernet-like drivers all have already.

      net: ethernet: mediatek: use dev_kfree_skb_any instead of dev_kfree_skb · 81ad2b7d

      Replace dev_kfree_skb with dev_kfree_skb_any in mtk_start_xmit()
      which can be called from hard irq context (netpoll) and from
      other contexts. mtk_start_xmit() only frees skbs that it has

      net: fec: drop check for clk==NULL before calling clk_* · 01e5943a
      Uwe Kleine-König authored
      clk_prepare, clk_enable and their counterparts (at least the common clk
      ones, but also most others) do check for the clk being NULL anyhow (and
      return 0 then), so there is no gain when the caller checks, too.

      tcp: relax listening_hash operations · 9652dc2e
      Eric Dumazet authored
      softirq handlers use RCU protection to lookup listeners,
      and write operations all happen from process context.
      We do not need to block BH for dump operations.
      
      Also SYN_RECV since request sockets are stored in the ehash table :
      
       1) inet_diag_dump_icsk() no longer need to clear
          cb->args[3] and cb->args[4] that were used as cursors while
          iterating the old per listener hash table.
      
       2) Also factorize a test : No need to scan listening_hash[]
          if r->id.idiag_dport is not zero.

      net: smc91x: fix neponset breakage by pxa u16 writes · 25c07e2c
      Robert Jarzmik authored
      The patch isolating the u16 writes for pxa assumed all machine_is_*()
      calls were removed, and therefore removed the mach-types.h include which
      provided them.
      
      Unfortunately 2 machine_is_*() remained in smc91x.c file including
      smc91x.h from which the include was removed, triggering the error:
       drivers/net/ethernet/smsc/smc91x.c: In function ‘smc_drv_probe’:
       drivers/net/ethernet/smsc/smc91x.c:2380:2: error: implicit declaration
       of function ‘machine_is_assabet’
       [-Werror=implicit-function-declaration]
      	if (machine_is_assabet() && machine_has_neponset())
      
      This adds back the wrongly removed include.

      ila: Fix tailroom allocation of lwtstate · c5098ebb
      Thomas Graf authored
      Tailroom is supposed to be of length sizeof(struct ila_lwt) but
      sizeof(struct ila_params) is currently allocated.
      
      This leads to the dst_cache and connected member of ila_lwt being
      referenced out of bounds.
      
      struct ila_lwt {
      	struct ila_params p;
      	struct dst_cache dst_cache;
      	u32 connected : 1;
