      libcrc32c: Add crc32c_le macro · 0426c166
      由 Herbert Xu 提交于 
      The bnx2x driver actually uses the crc32c_le name so this patch
restores the crc32c_le symbol through a macro.

      libcrc32c: Move implementation to crypto crc32c · 69c35efc
      由 Herbert Xu 提交于 
      This patch swaps the role of libcrc32c and crc32c.  Previously
the implementation was in libcrc32c and crc32c was a wrapper.
Now the code is in crc32c and libcrc32c just calls the crypto
layer.

The reason for the change is to tap into the algorithm selection
capability of the crypto API so that optimised implementations
such as the one utilising Intel's CRC32C instruction can be
used where available.

      crypto: hash - Export shash through hash · 5f7082ed
      由 Herbert Xu 提交于 
      This patch allows shash algorithms to be used through the old hash
interface.  This is a transitional measure so we can convert the
underlying algorithms to shash before converting the users across.

      crypto: hash - Add import/export interface · dec8b786
      由 Herbert Xu 提交于 
      It is often useful to save the partial state of a hash function
so that it can be used as a base for two or more computations.

The most prominent example is HMAC where all hashes start from
a base determined by the key.  Having an import/export interface
means that we only have to compute that base once rather than
for each message.

      This patch allows shash algorithms to be used through the ahash

      crypto: hash - Add shash interface · 7b5a080b
      由 Herbert Xu 提交于 
      The shash interface replaces the current synchronous hash interface.
It improves over hash in two ways.  Firstly shash is reentrant,
meaning that the same tfm may be used by two threads simultaneously
as all hashing state is stored in a local descriptor.

The other enhancement is that shash no longer takes scatter list
entries.  This is because shash is specifically designed for
synchronous algorithms and as such scatter lists are unnecessary.

All existing hash users will be converted to shash once the
algorithms have been completely converted.

There is also a new finup function that combines update with final.
This will be extended to ahash once the algorithm conversion is
done.

This is also the first time that an algorithm type has their own
registration function.  Existing algorithm types will be converted
to this way in due course.

      crypto: api - Rebirth of crypto_alloc_tfm · 7b0bac64
      由 Herbert Xu 提交于 
      This patch reintroduces a completely revamped crypto_alloc_tfm.
The biggest change is that we now take two crypto_type objects
when allocating a tfm, a frontend and a backend.  In fact this
simply formalises what we've been doing behind the API's back.

For example, as it stands crypto_alloc_ahash may use an
actual ahash algorithm or a crypto_hash algorithm.  Putting
this in the API allows us to do this much more cleanly.

The existing types will be converted across gradually.

      crypto: api - Move type exit function into crypto_tfm · 4a779486
      由 Herbert Xu 提交于 
      The type exit function needs to undo any allocations done by the type
init function.  However, the type init function may differ depending
on the upper-level type of the transform (e.g., a crypto_blkcipher
instantiated as a crypto_ablkcipher).

So we need to move the exit function out of the lower-level
structure and into crypto_tfm itself.

As it stands this is a no-op since nobody uses exit functions at
all.  However, all cases where a lower-level type is instantiated
as a different upper-level type (such as blkcipher as ablkcipher)
will be converted such that they allocate the underlying transform
and use that instead of casting (e.g., crypto_ablkcipher casted
into crypto_blkcipher).  That will need to use a different exit
function depending on the upper-level type.

This patch also allows the type init/exit functions to call (or not)
cra_init/cra_exit instead of always calling them from the top level.

      ipv6: Add IPV6_PKTINFO sticky option support to setsockopt() · b24a2516
      由 Yang Hongyang 提交于 
      There are three reasons for me to add this support:
1.When no interface is specified in an IPV6_PKTINFO ancillary data
  item, the interface specified in an IPV6_PKTINFO sticky optionis 
  is used.

RFC3542:
6.7.  Summary of Outgoing Interface Selection

   This document and [RFC-3493] specify various methods that affect the
   selection of the packet's outgoing interface.  This subsection
   summarizes the ordering among those in order to ensure deterministic
   behavior.

   For a given outgoing packet on a given socket, the outgoing interface
   is determined in the following order:

   1. if an interface is specified in an IPV6_PKTINFO ancillary data
      item, the interface is used.

   2. otherwise, if an interface is specified in an IPV6_PKTINFO sticky
      option, the interface is used.

2.When no IPV6_PKTINFO ancillary data is received,getsockopt() should 
  return the sticky option value which set with setsockopt().

RFC 3542:
   Issuing getsockopt() for the above options will return the sticky
   option value i.e., the value set with setsockopt().  If no sticky
   option value has been set getsockopt() will return the following
   values:

3.Make the setsockopt implementation POSIX compliant.

      net: Refactor full duplex flow control resolution · bc02ff95
      由 Steve Glendinning 提交于 
      These 4 drivers have identical full duplex flow control resolution
functions.  This patch changes them all to use one common function.

The function in question decides whether a device should enable TX and
RX flow control in a standard way (IEEE 802.3-2005 table 28B-3), so this
should also be useful for other drivers.

      net: Move flow control definitions to mii.h · e18ce346
      由 Steve Glendinning 提交于 
      flags used within drivers for indicating tx and rx flow control are
defined in 4 drivers (and probably more), move these constants to mii.h.

The 3 SMSC drivers use the same constants (FLOW_CTRL_TX), but TG3 uses
TG3_FLOW_CTRL_TX, so this patch also renames the constants within TG3.

      netfilter: ctnetlink: fix missing CTA_NAT_SEQ_UNSPEC · 092cab7e
      由 Pablo Neira Ayuso 提交于 
      This patch fixes an inconsistency in nfnetlink_conntrack.h that
I introduced myself. The problem is that CTA_NAT_SEQ_UNSPEC is
missing from enum ctattr_natseq. This inconsistency may lead to
problems in the message parsing in userspace (if the message
contains the CTA_NAT_SEQ_* attributes, of course).

This patch breaks backward compatibility, however, the only known
client of this code is libnetfilter_conntrack which indeed crashes
because it assumes the existence of CTA_NAT_SEQ_UNSPEC to do
the parsing.

The CTA_NAT_SEQ_* attributes were introduced in 2.6.25.

      net: Add skb_gro_receive · 71d93b39
      由 Herbert Xu 提交于 
      This patch adds the helper skb_gro_receive to merge packets for
GRO.  The current method is to allocate a new header skb and then
chain the original packets to its frag_list.  This is done to
make it easier to integrate into the existing GSO framework.

In future as GSO is moved into the drivers, we can undo this and
simply chain the original packets together.
