We do not allow spaces in algorithm names or parameters. Thanks to Joy Latten for pointing this out. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

As Joy Latten points out, inner algorithm parameters will miss the closing bracket which will also cause the outer algorithm to terminate prematurely. This patch fixes that also kills the WARN_ON if the number of parameters exceed the maximum as that is a user error. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

XTS currently considered to be the successor of the LRW mode by the IEEE1619 workgroup. LRW was discarded, because it was not secure if the encyption key itself is encrypted with LRW. XTS does not have this problem. The implementation is pretty straightforward, a new function was added to gf128mul to handle GF(128) elements in ble format. Four testvectors from the specification http://grouper.ieee.org/groups/1619/email/pdf00086.pdf were added, and they verify on my system.

When scatterwalk is built as a module digest.c was broken because it requires the crypto_km_types structure which is in scatterwalk. This patch removes the crypto_km_types structure by encoding the logic into crypto_kmap_type directly. In fact, this even saves a few bytes of code (not to mention the data structure itself) on i386 which is about the only place where it's needed.

This patch adds the authenc algorithm which constructs an AEAD algorithm from an asynchronous block cipher and a hash. The construction is done by concatenating the encrypted result from the cipher with the output from the hash, as is used by the IPsec ESP protocol. The authenc algorithm exists as a template with four parameters: authenc(auth, authsize, enc, enckeylen). The authentication algorithm, the authentication size (i.e., truncating the output of the authentication algorithm), the encryption algorithm, and the encryption key length. Both the size field and the key length field are in bytes. For example, AES-128 with SHA1-HMAC would be represented by authenc(hmac(sha1), 12, cbc(aes), 16) The key for the authenc algorithm is the concatenation of the keys for the authentication algorithm with the encryption algorithm. For the above example, if a key of length 36 bytes is given, then hmac(sha1) would receive the first 20 bytes while the last 16 would be given to cbc(aes).

This patch changes the return type of crypto_*_reqsize from int to unsigned int which matches what the underlying type is (and should be). Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

This patch adds the function scatterwalk_map_and_copy which reads or writes a chunk of data from a scatterlist at a given offset. It will be used by authenc which would read/write the authentication data at the end of the cipher/plain text. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

This patch adds support for having multiple parameters to a template, separated by a comma. It also adds support for integer parameters in addition to the current algorithm parameter type. This will be used by the authenc template which will have four parameters: the authentication algorithm, the encryption algorithm, the authentication size and the encryption key length.

This patch adds crypto_aead which is the interface for AEAD (Authenticated Encryption with Associated Data) algorithms. AEAD algorithms perform authentication and encryption in one step. Traditionally users (such as IPsec) would use two different crypto algorithms to perform these. With AEAD this comes down to one algorithm and one operation. Of course if traditional algorithms were used we'd still be doing two operations underneath. However, real AEAD algorithms may allow the underlying operations to be optimised as well.

This patch adds support for the SEED cipher (RFC4269). This patch have been used in few VPN appliance vendors in Korea for several years. And it was verified by KISA, who developed the algorithm itself. As its importance in Korean banking industry, it would be great if linux incorporates the support.

This concerns the ipv4 and ipv6 code mostly, but also the netlink and unix sockets. The netlink code is an example of how to use the __seq_open_private() call - it saves the net namespace on this private. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S.

Commit da3dedd9 ("[NET]: Make NAPI polling independent of struct net_device objects.") changed the interface to NAPI polling. Fix up the ibm_newemac driver so that it works with this new interface. This is actually a nice cleanup because ibm_newemac is one of the drivers that wants to have multiple NAPI structures for a single net_device. Compile-tested only as I don't have a system that uses the ibm_newemac driver. This conversion the conversion for the ibm_emac driver that was tested on real PowerPC 440SPe hardware.

Problem description by Daniel Drake <dsd@gentoo.org>: "This sequence of events causes loss of connectivity: <plug in> <associate as normal in managed mode> ifconfig eth7 down iwconfig eth7 mode monitor ifconfig eth7 up ifconfig eth7 down iwconfig eth7 mode managed <associate as normal> At this point you are associated but TX does not work. This is because the eth7 hard_start_xmit is still ieee80211_monitor_start_xmit." The problem is caused by ieee80211_if_set_type checking for a non-zero hard_start_xmit pointer value in order to avoid changing that value for master devices. The fix is to make that check more explicitly linked to master devices rather than simply checking if the value has been previously set.
