      net: bcmgenet: fix skb_len in bcmgenet_xmit_single() · 7dd39913
      Petri Gynther authored
      skb_len needs to be skb_headlen(skb) in bcmgenet_xmit_single().
      
      Fragmented skbs can have only Ethernet + IP + TCP headers (14+20+20=54 bytes)
      in the linear buffer, followed by the rest in fragments. Bumping skb_len to
      ETH_ZLEN would be incorrect for this case, as it would introduce garbage
      between TCP header and the fragment data.
      
      This also works with regular/non-fragmented small packets < ETH_ZLEN bytes.
      Successfully tested this on GENETv3 with 42-byte ARP frames.
      
      For testing, I used:
      ethtool -K eth0 tx-checksum-ipv4 off
      ethtool -K eth0 tx-checksum-ipv6 off
      echo 0 > /proc/sys/net/ipv4/tcp_timestamps

      net: bcmgenet: fix dev->stats.tx_bytes accounting · 55868120
      Petri Gynther authored
      1. Add bytes_compl local variable to __bcmgenet_tx_reclaim() to collect
         transmitted bytes. dev->stats updates can then be moved outside the
         while-loop. bytes_compl is also needed for future BQL support.
      2. When bcmgenet device uses Tx checksum offload, each transmitted skb
         gets an extra 64-byte header prepended to it. Before this header is
         prepended to the skb, we need to save the skb "wire" length in
         GENET_CB(skb)->bytes_sent, so that proper Tx bytes accounting can
         be done in __bcmgenet_tx_reclaim().
      3. skb->len covers the entire length of skb, whether it is linear or
         fragmented. Thus, when we clean the fragments, do not increase
         transmitted bytes.

      net: macb: replace macb_writel() call by queue_writel() to update queue ISR · ba504994
      Cyrille Pitchen authored
      macb_interrupt() should not use macb_writel(bp, ISR, <value>) but only
      queue_writel(queue, ISR, <value>).
      
      There is one IRQ and one set of {ISR, IER, IDR, IMR} [1] registers per
      queue on gem hardware, though only queue0 is actually used for now to
      receive frames: other queues can already be used to transmit frames.
      
      The queue_readl() and queue_writel() helper macros are designed to access
      the relevant IRQ registers.

      net: hns: bug fix about getting hilink status for HNS v2 · c1203fe7
      Sheng Li authored
      The hilink status reg in HNS V2 is different from HNS v1. In HNS V2, It
      distinguishes differnt lane status according to the bit-field of the reg.
      As is shown below:
      [0:0] ---> lane0
      [1:1] ---> lane1
      ...
      
      But the current driver reads the reg to get the hilink status ONLY
      concidering HNS V1 situation. Here is a patch to support both of them.

      There is a misuse of PTR as shown below:
      
      	ae_node = (void *)of_parse_phandle(dev->of_node,
      					   "ae-handle",
      					   0);
      	if (IS_ERR_OR_NULL(ae_node)) {
      		ret = PTR_ERR(ae_node);
      		dev_err(dev, "not find ae-handle\n");
      		goto out_read_prop_fail;
      	}
      
      if the ae_node is NULL, PTR_ERR(ae_node) means it returns success. And the
      return value should be -ENODEV.

      xfrm: Fix crash observed during device unregistration and decryption · 071d36bf
      subashab@codeaurora.org authored
      A crash is observed when a decrypted packet is processed in receive
      path. get_rps_cpus() tries to dereference the skb->dev fields but it
      appears that the device is freed from the poison pattern.

           |      dev = 0xFFFFFFC08B688000 -> (
           |        name =
      "......................................................
           |        name_hlist = (next = 0xAAAAAAAAAAAAAAAA, pprev =
      0xAAAAAAAAAAA
      
      Following are the sequence of events observed -
      
      - Encrypted packet in receive path from netdevice is queued
      - Encrypted packet queued for decryption (asynchronous)
      - Netdevice brought down and freed
      - Packet is decrypted and returned through callback in esp_input_done
      - Packet is queued again for process in network stack using netif_rx
      
      Since the device appears to have been freed, the dereference of
      skb->dev in get_rps_cpus() leads to an unhandled page fault
      exception.
      
      Fix this by holding on to device reference when queueing packets
      asynchronously and releasing the reference on call back return.

       - Fix a regression where bogus trip points on some Lenovo laptops start
         to screw up thermal control after commit 81ad4276 ("Thermal:
         initialize thermal zone device correctly").
      
         On these Lenovo laptops, a bogus passive trip point is reported,
         which is 0 degree Celsius.  Without commit 81ad4276, thermal zone
         fails to set cooling devices to proper cooling state, which is a bug.
         But with commit 81ad4276 applied, the processors are always
         throttled on these Lenovo laptops because the current temperature is
         always higher than the passive trip point.
      
         Fix things to ignore such bogus trip points.  (Zhang Rui)

       - Move utilities.mak from perf to tools/scripts/ (Arnaldo Carvalho de Melo)

         the union event to the machine and thread resolving routines, shortening
         function signatures and allowing the future introduction of a way
         to use tracepoint events instead of the unavailable HW cycles counter on

       - Stop using strbuf for things we can instead trivially use libc's asprintf()
         (Arnaldo Carvalho de Melo)
      
       - Ditch tools/lib/util/abspath.c, its only exported function was used at just
         one place and can be replaced by libc's realpath() (Arnaldo Carvalho de Melo)
      
       - Use strerror_r() in the llvm infrastructure, tread safe, its what is used
         elsewhere in tools/perf/ (Arnaldo Carvalho de Melo)

      Reorder the code in netvsc_sc_open(), so num_sc_offered is only decremented
      after vmbus_open() is called. This avoid pontential race of removing device
      before all channels are setup.
