net: move pskb_put() to core code

2013-11-08T00:28:58+00:00

This function has usage beside IPsec so move it to the core skbuff code.
While doing so, give it some documentation and change its return type to
'unsigned char *' to be in line with skb_put().

net: esp{4,6}: get rid of struct esp_data

2013-10-29T05:39:42+00:00

struct esp_data consists of a single pointer, vanishing the need for it
to be a structure. Fold the pointer into 'data' direcly, removing one
level of pointer indirection.

The padlen member of struct esp_data is always zero. Get rid of it.

esp.h: Remove extern from function prototypes

2013-09-20T18:49:32+00:00

There are a mix of function prototypes with and without extern
in the kernel sources.  Standardize on not using extern for
function prototypes.

Function prototypes don't need to be written with extern.
extern is assumed by the compiler.  Its use is as unnecessary as
using auto to declare automatic/local variables in a block.

[IPSEC]: Use crypto_aead and authenc in ESP

2008-02-01T03:27:02+00:00

This patch converts ESP to use the crypto_aead interface and in particular
the authenc algorithm.  This lays the foundations for future support of
combined mode algorithms.

cleanup asm/scatterlist.h includes

2007-11-02T07:47:06+00:00

Not architecture specific code should not #include .

This patch therefore either replaces them with
#include  or simply removes them if they were
unused.

[IPSEC]: Get rid of ipv6_{auth,esp,comp}_hdr

2007-10-10T23:55:55+00:00

This patch removes the duplicate ipv6_{auth,esp,comp}_hdr structures since
they're identical to the IPv4 versions.  Duplicating them would only create
problems for ourselves later when we need to add things like extended
sequence numbers.

I've also added transport header type conversion headers for these types
which are now used by the transforms.

[IPSEC] esp: Remove keys from esp_data structure

2007-10-10T23:54:52+00:00

The keys are only used during initialisation so we don't need to carry them
in esp_data.  Since we don't have to allocate them again, there is no need
to place a limit on the authentication key length anymore.

This patch also kills the unused auth.icv member.

[NET]: Move generic skbuff stuff from XFRM code to generic code

2007-04-26T05:28:33+00:00

Move generic skbuff stuff from XFRM code to generic code so that
AF_RXRPC can use it too.

The kdoc comments I've attached to the functions needs to be checked
by whoever wrote them as I had to make some guesses about the workings
of these functions.

[IPSEC] esp: Defer output IV initialization to first use.

2006-09-22T22:17:35+00:00

First of all, if the xfrm_state only gets used for input
packets this entropy is a complete waste.

Secondly, it is often the case that a configuration loads
many rules (perhaps even dynamically) and they don't all
necessarily ever get used.

This get_random_bytes() call was showing up in the profiles
for xfrm_state inserts which is how I noticed this.
