      qlge: Expand coverage of hw lock for config register. · 4322c5be
      由 Ron Mercer 提交于 
      The hardware semaphore covers the configuration register as well as the
ICB registers.  The ICB high and low regs contain the address of the
initialization control block and the config register is used to signal
the hardware that a block is ready to be downloaded.  Currently we were
only protecting the ICB regs.  This changes expands to cover the config
register as well.

      IPv6: preferred lifetime of address not getting updated · a1ed0526
      由 Brian Haley 提交于 
      There's a bug in addrconf_prefix_rcv() where it won't update the
preferred lifetime of an IPv6 address if the current valid lifetime
of the address is less than 2 hours (the minimum value in the RA).

For example, If I send a router advertisement with a prefix that
has valid lifetime = preferred lifetime = 2 hours we'll build
this address:

3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
    inet6 2001:1890:1109:a20:217:8ff:fe7d:4718/64 scope global dynamic
       valid_lft 7175sec preferred_lft 7175sec

If I then send the same prefix with valid lifetime = preferred
lifetime = 0 it will be ignored since the minimum valid lifetime
is 2 hours:

3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
    inet6 2001:1890:1109:a20:217:8ff:fe7d:4718/64 scope global dynamic
       valid_lft 7161sec preferred_lft 7161sec

But according to RFC 4862 we should always reset the preferred lifetime
even if the valid lifetime is invalid, which would cause the address
to immediately get deprecated.  So with this patch we'd see this:

5: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
    inet6 2001:1890:1109:a20:21f:29ff:fe5a:ef04/64 scope global deprecated dynamic
       valid_lft 7163sec preferred_lft 0sec

The comment winds-up being 5x the size of the code to fix the problem.

Update the preferred lifetime of IPv6 addresses derived from a prefix
info option in a router advertisement even if the valid lifetime in
the option is invalid, as specified in RFC 4862 Section 5.5.3e.  Fixes
an issue where an address will not immediately become deprecated.

      xfrm6: fix the proto and ports decode of sctp protocol · 59cae009
      由 Wei Yongjun 提交于 
      The SCTP pushed the skb above the sctp chunk header, so the
check of pskb_may_pull(skb, nh + offset + 1 - skb->data) in
_decode_session6() will never return 0 and the ports decode
of sctp will always fail. (nh + offset + 1 - skb->data < 0)

      xfrm4: fix the ports decode of sctp protocol · c615c9f3
      由 Wei Yongjun 提交于 
      The SCTP pushed the skb data above the sctp chunk header, so the check
of pskb_may_pull(skb, xprth + 4 - skb->data) in _decode_session4() will
never return 0 because xprth + 4 - skb->data < 0, the ports decode of
sctp will always fail.
