      amd-xgbe: Use __napi_schedule() in BH context · d518691c
      Sebastian Andrzej Siewior authored
      The driver uses __napi_schedule_irqoff() which is fine as long as it is
      invoked with disabled interrupts by everybody. Since the commit
      mentioned below the driver may invoke xgbe_isr_task() in tasklet/softirq
      context. This may lead to list corruption if another driver uses
      __napi_schedule_irqoff() in IRQ context.
      
      Use __napi_schedule() which safe to use from IRQ and softirq context.

      net: stmmac: dwmac-sunxi: Provide TX and RX fifo sizes · 806fd188
      Florian Fainelli authored
      After commit bfcb8132 ("net: dsa:
      configure the MTU for switch ports") my Lamobo R1 platform which uses
      an allwinner,sun7i-a20-gmac compatible Ethernet MAC started to fail
      by rejecting a MTU of 1536. The reason for that is that the DMA
      capabilities are not readable on this version of the IP, and there
      is also no 'tx-fifo-depth' property being provided in Device Tree. The
      property is documented as optional, and is not provided.
      
      Chen-Yu indicated that the FIFO sizes are 4KB for TX and 16KB for RX, so
      provide these values through platform data as an immediate fix until
      various Device Tree sources get updated accordingly.

      Pull tracing fix from Steven Rostedt:
       "This fixes a small race between allocating a snapshot buffer and
        setting the snapshot trigger.
      
        On a slow machine, the trigger can occur before the snapshot is
        allocated causing a warning to be displayed in the ring buffer, and no
        snapshot triggering. Reversing the allocation and the enabling of the
        trigger fixes the problem"

      keys: Fix proc_keys_next to increase position index · 86d32f9a
      Vasily Averin authored
      If seq_file .next function does not change position index,
      read after some lseek can generate unexpected output:
      
          $ dd if=/proc/keys bs=1  # full usual output
          0f6bfdf5 I--Q---     2 perm 3f010000  1000  1000 user      4af2f79ab8848d0a: 740
          1fb91b32 I--Q---     3 perm 1f3f0000  1000 65534 keyring   _uid.1000: 2
          27589480 I--Q---     1 perm 0b0b0000     0     0 user      invocation_id: 16
          2f33ab67 I--Q---   152 perm 3f030000     0     0 keyring   _ses: 2

          521+0 records out
          521 bytes copied, 0,00123769 s, 421 kB/s
      
      But a read after lseek in middle of last line results in the partial
      last line and then a repeat of the final line:
      
          $ dd if=/proc/keys bs=500 skip=1
          dd: /proc/keys: cannot skip to specified offset
          g   _uid_ses.1000: 1
          3ead4096 I--Q---     1 perm 1f3f0000  1000 65534 keyring   _uid_ses.1000: 1

          0+1 records out
          97 bytes copied, 0,000135035 s, 718 kB/s
      
      and a read after lseek beyond end of file results in the last line being
      shown:
      
          $ dd if=/proc/keys bs=1000 skip=1   # read after lseek beyond end of file
          dd: /proc/keys: cannot skip to specified offset
