      net: Support specifying the network namespace upon device creation. · 81adee47
      由 Eric W. Biederman 提交于 
      There is no good reason to not support userspace specifying the
network namespace during device creation, and it makes it easier
to create a network device and pass it to a child network namespace
with a well known name.

We have to be careful to ensure that the target network namespace
for the new device exists through the life of the call.  To keep
that logic clear I have factored out the network namespace grabbing
logic into rtnl_link_get_net.

In addtion we need to continue to pass the source network namespace
to the rtnl_link_ops.newlink method so that we can find the base
device source network namespace.

      can: provide library functions for skb allocation · 7b6856a0
      由 Wolfgang Grandegger 提交于 
      This patch makes the private functions alloc_can_skb() and
alloc_can_err_skb() of the at91_can driver public and adapts all
drivers to use these. While making the patch I realized, that
the skb's are *not* setup consistently. It's now done as shown
below:

  skb->protocol = htons(ETH_P_CAN);
  skb->pkt_type = PACKET_BROADCAST;
  skb->ip_summed = CHECKSUM_UNNECESSARY;
  *cf = (struct can_frame *)skb_put(skb, sizeof(struct can_frame));
  memset(*cf, 0, sizeof(struct can_frame));

The frame is zeroed out to avoid uninitialized data to be passed to
user space. Some drivers or library code did not set "pkt_type" or
"ip_summed". Also,  "__constant_htons()" should not be used for
runtime invocations, as pointed out by David Miller.

      can: sja1000: legacy SJA1000 ISA bus driver · 2a6ba39a
      由 Wolfgang Grandegger 提交于 
      This patch adds support for legacy SJA1000 CAN controllers on the ISA
or PC-104 bus. The I/O port or memory address and the IRQ number must
be specified via module parameters:

  insmod sja1000_isa.ko port=0x310,0x380 irq=7,11

for ISA devices using I/O ports or:

  insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11

for memory mapped ISA devices.

Indirect access via address and data port is supported as well:

  insmod sja1000_isa.ko port=0x310,0x380 indirect=1 irq=7,11

Here is a full list of the supported module parameters:

  port:I/O port number (array of ulong)
  mem:I/O memory address (array of ulong)
  indirect:Indirect access via address and data port (array of byte)
  irq:IRQ number (array of int)
  clk:External oscillator clock frequency (default=16000000 [16 MHz])
      (array of int)
  cdr:Clock divider register (default=0x48 [CDR_CBP | CDR_CLK_OFF])
      (array of byte)
  ocr:Output clock register (default=0x18 [OCR_TX0_PUSHPULL])
      (array of byte)

Note: for clk, cdr, ocr, the first argument re-defines the default
for all other devices, e.g.:

 insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000

is equivalent to

 insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11 \
                       clk=24000000,24000000

      由 Wolfgang Grandegger 提交于 
      The member "tx_bytes" of "struct net_device_stats" should be
incremented when the interrupt is done and an "arbitration
lost error" is a TX error and the statistics should be updated
accordingly.
