      net/stmmac: mark probe function as __devinit · f5addb91
      Arnd Bergmann authored
      Driver probe functions are generally __devinit so they will be
      discarded after initialization for non-hotplug kernels.
      This was found by a new warning after patch 6a228452 "stmmac: Add
      device-tree support" adds a new __devinit function that is called
      from stmmac_pltfr_probe.
      
      Without this patch, building socfpga_defconfig results in:
      
      WARNING: drivers/net/ethernet/stmicro/stmmac/stmmac.o(.text+0x5d4c): Section mismatch in reference from the function stmmac_pltfr_probe() to the function .devinit.text:stmmac_probe_config_dt()
      The function stmmac_pltfr_probe() references
      the function __devinit stmmac_probe_config_dt().
      This is often because stmmac_pltfr_probe lacks a __devinit
      annotation or the annotation of stmmac_probe_config_dt is wrong.

      cdc-phonet: Don't leak in usbpn_open · 47dffc75
      Jesper Juhl authored
      We allocate memory for 'req' with usb_alloc_urb() and then test
      'if (!req || rx_submit(pnd, req, GFP_KERNEL | __GFP_COLD))'.
      If we enter that branch due to '!req' then there is no problem. But if
      we enter the branch due to 'req' being != 0 and the 'rx_submit()' call
      being false, then we'll leak the memory we allocated.
      Deal with the leak by always calling 'usb_free_urb(req)' when entering
      the branch. If 'req' happens to be 0 then the call is harmless, if it
      is not 0 then we free the memory we allocated but don't need.

      batman-adv: Fix mem leak in the batadv_tt_local_event() function · 155e4e12
      Jesper Juhl authored
      Memory is allocated for 'tt_change_node' with kmalloc().
      'tt_change_node' may go out of scope really being used for anything
      (except have a few members initialized) if we hit the 'del:' label.
      This patch makes sure we free the memory in that case.

      sched: add missing group change to qfq_change_class · be72f63b
      Paolo Valente authored
      [Resending again, as the text was corrupted by the email client]
      
      To speed up operations, QFQ internally divides classes into
      groups. Which group a class belongs to depends on the ratio between
      the maximum packet length and the weight of the class. Unfortunately
      the function qfq_change_class lacks the steps for changing the group
      of a class when the ratio max_pkt_len/weight of the class changes.
      
      For example, when the last of the following three commands is
      executed, the group of class 1:1 is not correctly changed:
      
      tc disc add dev XXX root handle 1: qfq
      tc class add dev XXX parent 1: qfq classid 1:1 weight 1
      tc class change dev XXX parent 1: classid 1:1 qfq weight 4
      
      Not changing the group of a class does not affect the long-term
      bandwidth guaranteed to the class, as the latter is independent of the
      maximum packet length, and correctly changes (only) if the weight of
      the class changes. In contrast, if the group of the class is not
      updated, the class is still guaranteed the short-term bandwidth and
      packet delay related to its old group, instead of the guarantees that
      it should receive according to its new weight and/or maximum packet
      length. This may also break service guarantees for other classes.
      This patch adds the missing operations.

      net: force dst_default_metrics to const section · a37e6e34
      Eric Dumazet authored
      While investigating on network performance problems, I found this little
      gem :
      
      $ nm -v vmlinux | grep -1 dst_default_metrics
      ffffffff82736540 b busy.46605
      ffffffff82736560 B dst_default_metrics
      ffffffff82736598 b dst_busy_list
      
      Apparently, declaring a const array without initializer put it in
      (writeable) bss section, in middle of possibly often dirtied cache
      lines.
      
      Since we really want dst_default_metrics be const to avoid any possible
      false sharing and catch any buggy writes, I force a null initializer.

      net: fib: fix incorrect call_rcu_bh() · 0c03eca3
      Eric Dumazet authored
      After IP route cache removal, I believe rcu_bh() has very little use and
      we should remove this RCU variant, since it adds some cycles in fast
      path.
      
      Anyway, the call_rcu_bh() use in fib_true is obviously wrong, since
      some users only assert rcu_read_lock().

      pptp: lookup route with the proper net namespace · 08252b32
      Gao feng authored
      pptp always use init_net as the net namespace to lookup
      route, this will cause route lookup failed in container.
      
      because we already set the correct net namespace to struct
      sock in pptp_create,so fix this by using sock_net(sk) to
      replace &init_net.
