2012-10-08Blackfin: cpufreq: fix dpm_state_tableJames Cosin
This patch fixes an assumption that cclk's initial divisor will always be 1 (or 0 in the register). TSCALE is always initialized on startup with a value of 4 regardless of the inital cclk divisor; so, we can't make the assumption without making lots of other assumptions. The TPERIOD value is set with a value of the current cclk (value / (HZ * TSCALE)) - 1; so, we need to adjust based on this initial frequency and not use cclk's initial divisor for adjusting the tscale.

2012-10-08X.509: Add a crypto key parser for binary (DER) X.509 certificatesDavid Howells
Add a crypto key parser for binary (DER) encoded X.509 certificates. The certificate is parsed and, if possible, the signature is verified. An X.509 key can be added like this: # keyctl padd crypto bar @s </tmp/x509.cert 15768135 and displayed like this: # cat /proc/keys 00f09a47 I--Q--- 1 perm 39390000 0 0 asymmetri bar: X509.RSA e9fd6d08 [] Note that this only works with binary certificates. PEM encoded certificates are ignored by the parser. Note also that the X.509 key ID is not congruent with the PGP key ID, but for the moment, they will match. If a NULL or "" name is given to add_key(), then the parser will generate a key description from the CertificateSerialNumber and Name fields of the TBSCertificate: 00aefc4e I--Q--- 1 perm 39390000 0 0 asymmetri bfbc0cd76d050ea4:/C=GB/L=Cambridge/O=Red Hat/CN=kernel key: X509.RSA 0c688c7b [] Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2012-10-08MPILIB: Provide a function to read raw data into an MPIDavid Howells
Provide a function to read raw data of a predetermined size into an MPI rather than expecting the size to be encoded within the data. The data is assumed to represent an unsigned integer, and the resulting MPI will be positive. The function looks like this: MPI mpi_read_raw_data(const void *, size_t); This is useful for reading ASN.1 integer primitives where the length is encoded in the ASN.1 metadata.

2012-10-08X.509: Add an ASN.1 decoderDavid Howells
Add an ASN.1 BER/DER/CER decoder. This uses the bytecode from the ASN.1 compiler in the previous patch to inform it as to what to expect to find in the encoded byte stream. The output from the compiler also tells it what functions to call on what tags, thus allowing the caller to retrieve information. The decoder is called as follows: int asn1_decoder(const struct asn1_decoder *decoder, void *context, const unsigned char *data, size_t datalen); The decoder argument points to the bytecode from the ASN.1 compiler. context is the caller's context and is passed to the action functions. data and datalen define the byte stream to be decoded. Note that the decoder is currently limited to datalen being less than 64K. This reduces the amount of stack space used by the decoder because ASN.1 is a nested construct. Similarly, the decoder is limited to a maximum of 10 levels of constructed data outside of a leaf node also in an effort to keep stack usage down. These restrictions can be raised if necessary.

2012-10-08X.509: Add simple ASN.1 grammar compilerDavid Howells
Add a simple ASN.1 grammar compiler. This produces a bytecode output that can be fed to a decoder to inform the decoder how to interpret the ASN.1 stream it is trying to parse. Action functions can be specified in the grammar by interpolating: ({ foo }) after a type, for example: SubjectPublicKeyInfo ::= SEQUENCE { algorithm AlgorithmIdentifier, subjectPublicKey BIT STRING ({ do_key_data }) } The decoder is expected to call these after matching this type and parsing the contents if it is a constructed type. The grammar compiler does not currently support the SET type (though it does support SET OF) as I can't see a good way of tracking which members have been encountered yet without using up extra stack space. Currently, the grammar compiler will fail if more than 256 bytes of bytecode would be produced or more than 256 actions have been specified as it uses 8-bit jump values and action indices to keep space usage down.

2012-10-08X.509: Add utility functions to render OIDs as stringsDavid Howells
Add a pair of utility functions to render OIDs as strings. The first takes an encoded OID and turns it into a "a.b.c.d" form string: int sprint_oid(const void *data, size_t datasize, char *buffer, size_t bufsize); The second takes an OID enum index and calls the first on the data held therein: int sprint_OID(enum OID oid, char *buffer, size_t bufsize); Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2012-10-08X.509: Implement simple static OID registryDavid Howells
Implement a simple static OID registry that allows the mapping of an encoded OID to an enum value for ease of use. The OID registry index enum appears in the: linux/oid_registry.h header file. A script generates the registry from lines in the header file that look like: <sp*>OID_foo,<sp*>/*<sp*>1.2.3.4<sp*>*/ The actual OID is taken to be represented by the numbers with interpolated dots in the comment. All other lines in the header are ignored. The registry is queries by calling: OID look_up_oid(const void *data, size_t datasize); This returns a number from the registry enum representing the OID if found or OID__NR if not.

2012-10-08RSA: Fix signature verification for shorter signaturesDavid Howells
gpg can produce a signature file where length of signature is less than the modulus size because the amount of space an MPI takes up is kept as low as possible by discarding leading zeros.

2012-10-08KEYS: Provide signature verification with an asymmetric keyDavid Howells
Provide signature verification using an asymmetric-type key to indicate the public key to be used. The API is a single function that can be found in crypto/public_key.h: int verify_signature(const struct key *key, const struct public_key_signature *sig) The first argument is the appropriate key to be used and the second argument is the parsed signature data: struct public_key_signature { u8 *digest; u16 digest_size; enum pkey_hash_algo pkey_hash_algo : 8; union { MPI mpi[2]; struct { MPI s; /* m^d mod n */ } rsa; struct { MPI r; MPI s; } dsa; }; }; This should be filled in prior to calling the function. The hash algorithm should already have been called and the hash finalised and the output should be in a buffer pointed to by the 'digest' member. Any extra data to be added to the hash by the hash format (eg. PGP) should have been added by the caller prior to finalising the hash. It is assumed that the signature is made up of a number of MPI values. If an algorithm becomes available for which this is not the case, the above structure will have to change. It is also assumed that it will have been checked that the signature algorithm matches the key algorithm.

2012-10-08KEYS: Asymmetric key pluggable data parsersDavid Howells
The instantiation data passed to the asymmetric key type are expected to be formatted in some way, and there are several possible standard ways to format the data. The two obvious standards are OpenPGP keys and X.509 certificates. The latter is especially useful when dealing with UEFI, and the former might be useful when dealing with, say, eCryptfs. Further, it might be desirable to provide formatted blobs that indicate hardware is to be accessed to retrieve the keys or that the keys live unretrievably in a hardware store, but that the keys can be used by means of the hardware. From userspace, the keys can be loaded using the keyctl command, for example, an X.509 binary certificate: keyctl padd asymmetric foo @s <dhowells.pem or a PGP key: keyctl padd asymmetric bar @s <dhowells.pub or a pointer into the contents of the TPM: keyctl add asymmetric zebra "TPM:04982390582905f8" @s Inside the kernel, pluggable parsers register themselves and then get to examine the payload data to see if they can handle it. If they can, they get to: (1) Propose a name for the key, to be used it the name is "" or NULL. (2) Specify the key subtype. (3) Provide the data for the subtype. The key type asks the parser to do its stuff before a key is allocated and thus before the name is set. If successful, the parser stores the suggested data into the key_preparsed_payload struct, which will be either used (if the key is successfully created and instantiated or updated) or discarded.

2012-10-08KEYS: Implement asymmetric key typeDavid Howells
Create a key type that can be used to represent an asymmetric key type for use in appropriate cryptographic operations, such as encryption, decryption, signature generation and signature verification. The key type is "asymmetric" and can provide access to a variety of cryptographic algorithms. Possibly, this would be better as "public_key" - but that has the disadvantage that "public key" is an overloaded term.

2012-10-08KEYS: Add payload preparsing opportunity prior to key instantiate or updateDavid Howells
Give the key type the opportunity to preparse the payload prior to the instantiation and update routines being called. This is done with the provision of two new key type operations: int (*preparse)(struct key_preparsed_payload *prep); void (*free_preparse)(struct key_preparsed_payload *prep); If the first operation is present, then it is called before key creation (in the add/update case) or before the key semaphore is taken (in the update and instantiate cases). The second operation is called to clean up if the first was called. preparse() is given the opportunity to fill in the following structure: struct key_preparsed_payload { char *description; void *type_data[2]; void *payload; const void *data; size_t datalen; size_t quotalen; }; Before the preparser is called, the first three fields will have been cleared, the payload pointer and size will be stored in data and datalen and the default quota size from the key_type struct will be stored into quotalen. The preparser may parse the payload in any way it likes and may store data in the type_data[] and payload fields for use by the instantiate() and update() ops. The preparser may also propose a description for the key by attaching it as a string to the description field. This can be used by passing a NULL or "" description to the add_key() system call or the key_create_or_update() function. This cannot work with request_key() as that required the description to tell the upcall about the key to be created. This, for example permits keys that store PGP public keys to generate their own name from the user ID and public key fingerprint in the key. The instantiate() and update() operations are then modified to look like this: int (*instantiate)(struct key *key, struct key_preparsed_payload *prep); int (*update)(struct key *key, struct key_preparsed_payload *prep); and the new payload data is passed in *prep, whether or not it was preparsed.

2012-10-07ARM: OMAP2+: hwmod data: Fix PMU interrupt definitionsJon Hunter
Commit 7d7e1eb (ARM: OMAP2+: Prepare for irqs.h removal) and commit ec2c082 (ARM: OMAP2+: Remove hardcoded IRQs and enable SPARSE_IRQ) updated the way interrupts for OMAP2/3 devices are defined in the HWMOD data structures to being an index plus a fixed offset (defined by OMAP_INTC_START). The definition of the PMU interrupts on OMAP2/3 devices is missing the OMAP_INTC_START offset and so this is causing the allocation of PMU interrupts to fail on OMAP2/3 devices. So add the offset to fix this. This is patch is based upon Tony's master branch for OMAP. Signed-off-by: Jon Hunter <jon-hunter@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>

After Rajendra's common-clock preparation series, commit (a1978ef4da1 - ARM: omap: hwmod: get rid of all omap_clk_get_by_name usage) the clkdev table need to update with an entry for clocks used by hwmod to have clock name same as the alias.

2012-10-07net: gro: fix a potential crash in skb_gro_reset_offsetEric Dumazet
Before accessing skb first fragment, better make sure there is one. This is probably not needed for old kernels, since an ethernet frame cannot contain only an ethernet header, but the recent GRO addition to tunnels makes this patch needed. Also skb_gro_reset_offset() can be static, it actually allows compiler to inline it.

2012-10-07net: Fix skb_under_panic oops in neigh_resolve_outputramesh.nagappa@gmail.com
The retry loop in neigh_resolve_output() and neigh_connected_output() call dev_hard_header() with out reseting the skb to network_header. This causes the retry to fail with skb_under_panic. The fix is to reset the network_header within the retry loop.

2012-10-07drivers/net/ethernet/marvell/sky2.c: fix error return codePeter Senna Tschudin
The function sky2_probe() return 0 for success and negative value for most of its internal tests failures. There are two exceptions that are error cases going to err_out*:. For this two cases, the function abort its success execution path, but returns non negative value, making it dificult for a caller function to notice the error. This patch fixes the error cases that do not return negative values. This was found by Coccinelle, but the code change was made by hand. This patch is not robot generated. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by: Peter Senna Tschudin <peter.senna@gmail.com> Signed-off-by: David S.
