2011-03-22zlib: slim down zlib_deflate() workspace when possibleJim Keniston2-8/+13
Instead of always creating a huge (268K) deflate_workspace with the maximum compression parameters (windowBits=15, memLevel=8), allow the caller to obtain a smaller workspace by specifying smaller parameter values. For example, when capturing oops and panic reports to a medium with limited capacity, such as NVRAM, compression may be the only way to capture the whole report. In this case, a small workspace (24K works fine) is a win, whether you allocate the workspace when you need it (i.e., during an oops or panic) or at boot time. I've verified that this patch works with all accepted values of windowBits (positive and negative), memLevel, and compression level.

2011-01-29crypto: testmgr - mark ghash as fips_allowedJarod Wilson1-0/+1
A self-test failure in fips mode means a panic. Well, gcm(aes) self-tests currently fail in fips mode, as gcm is dependent on ghash, which semi-recently got self-test vectors added, but wasn't marked as a fips_allowed algorithm. Because of gcm's dependence on what is now seen as a non-fips_allowed algorithm, its self-tests refuse to run. Previously, ghash got a pass in fips mode, due to the lack of any test vectors at all, and thus gcm self-tests were able to run. After this patch, a 'modprobe tcrypt mode=35' no longer panics in fips mode, and successful self-test of gcm(aes) is reported.

We (Red Hat) are intending to include dm-crypt functionality, using xts(aes) for disk encryption, as part of an upcoming FIPS-140-2 certification effort, and xts(aes) *is* on the list of possible mode/cipher combinations that can be certified. To make that possible, we need to mark xts(aes) as fips_allowed in the crypto subsystem. A 'modprobe tcrypt mode=10' in fips mode shows xts(aes) self-tests passing successfully after this change.

2010-11-30crypto: algif_skcipher - Handle unaligned receive bufferHerbert Xu1-6/+7
As it is if user-space passes through a receive buffer that's not aligned to to the cipher block size, we'll end up encrypting or decrypting a partial block which causes a spurious EINVAL to be returned.

2010-11-30crypto: algif_skcipher - Fixed overflow when sndbuf is page alignedHerbert Xu1-21/+11
When sk_sndbuf is not a multiple of PAGE_SIZE, the limit tests in sendmsg fail as the limit variable becomes negative and we're using an unsigned comparison. The same thing can happen if sk_sndbuf is lowered after a sendmsg call. This patch fixes this by always taking the signed maximum of limit and 0 before we perform the comparison. It also rounds the value of sk_sndbuf down to a multiple of PAGE_SIZE so that we don't end up allocating a page only to use a small number of bytes in it because we're bound by sk_sndbuf.

2010-11-26crypto: algif_skcipher - User-space interface for skcipher operationsHerbert Xu3-0/+649
This patch adds the af_alg plugin for symmetric key ciphers, corresponding to the ablkcipher kernel operation type. Keys can optionally be set through the setsockopt interface. Once a sendmsg call occurs without MSG_MORE no further writes may be made to the socket until all previous data has been read. IVs and and whether encryption/decryption is performed can be set through the setsockopt interface or as a control message to sendmsg. The interface is completely synchronous, all operations are carried out in recvmsg(2) and will complete prior to the system call returning. The splice(2) interface support reading the user-space data directly without copying (except that the Crypto API itself may copy the data if alignment is off). The recvmsg(2) interface supports directly writing to user-space without additional copying, i.e., the kernel crypto interface will receive the user-space address as its output SG list.

2010-11-19crypto: algif_hash - User-space interface for hash operationsHerbert Xu3-0/+328
This patch adds the af_alg plugin for hash, corresponding to the ahash kernel operation type. Keys can optionally be set through the setsockopt interface. Each sendmsg call will finalise the hash unless sent with a MSG_MORE flag. Partial hash states can be cloned using accept(2). The interface is completely synchronous, all operations will complete prior to the system call returning. Both sendmsg(2) and splice(2) support reading the user-space data directly without copying (except that the Crypto API itself may copy the data if alignment is off). For now only the splice(2) interface supports performing digest instead of init/update/final. In future the sendmsg(2) interface will also be modified to use digest/finup where possible so that hardware that cannot return a partial hash state can still benefit from this interface.

2010-11-19crypto: af_alg - User-space interface for Crypto APIHerbert Xu3-0/+486
This patch creates the backbone of the user-space interface for the Crypto API, through a new socket family AF_ALG. Each session corresponds to one or more connections obtained from that socket. The number depends on the number of inputs/outputs of that particular type of operation. For most types there will be a s ingle connection/file descriptor that is used for both input and output. AEAD is one of the few that require two inputs. Each algorithm type will provide its own implementation that plugs into af_alg. They're keyed using a string such as "skcipher" or "hash". IOW this patch only contains the boring bits that is required to hold everything together. Thakns to Miloslav Trmac for reviewing this and contributing fixes and improvements.

I noticed that by factoring out common rounds from the branches of the if-statements in the encryption and decryption functions, the executable file size goes down significantly, for crypto/cast5.ko from 26688 bytes to 24336 bytes (amd64).

If a scatterwalk chain contains an entry with an unaligned offset then hash_walk_next() will cut off the next step at the next alignment point. However, if the entry ends before the next alignment point then we a loop, which leads to a kernel oops. Fix this by checking whether the next aligment point is before the end of the current entry.

2010-07-31crypto: pcrypt - Update pcrypt cpumask according to the padata cpumask notifierSteffen Klassert1-2/+11
The padata cpumask change notifier passes a padata_cpumask to the notifier chain. So we use this cpumask instead of asking padata for the cpumask. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2010-07-31crypto: pcrypt - Rename pcrypt_instanceSteffen Klassert1-16/+14
In the crypto-layer an instance refers usually to a crypto instance. The struct pcrypt_instance is not related to a crypto instance. It rather contains the padata informations, so we rename it to padata_pcrypt. The functions that handle this struct are renamed accordingly.

2010-07-31padata: Rename padata_alloc functionsSteffen Klassert1-1/+1
We rename padata_alloc to padata_alloc_possible because this function allocates a padata_instance and uses the cpu_possible mask for parallel and serial workers. Also we rename __padata_alloc to padata_alloc to avoid to export underlined functions. Underlined functions are considered to be private to padata. Users are updated accordingly.

2010-07-26crypto: pcrypt - Dont calulate a callback cpu on empty callback cpumaskSteffen Klassert1-0/+3
If the callback cpumask is empty, we crash with a division by zero when we try to calculate a callback cpu. So we don't update the callback cpu in pcrypt_do_parallel if the callback cpumask is empty.

2010-07-19pcrypt: Added sysfs interface to pcryptDan Kruchinin1-3/+32
Added sysfs interface to pcrypt. Now pcrypt subsystem creates two sysfs directories with corresponding padata sysfs objects: /sys/kernel/pcrypt/[pencrypt|pdecrypt] Signed-off-by: Dan Kruchinin <dkruchinin@acm.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2010-07-19padata: Make two separate cpumasksDan Kruchinin1-54/+137
The aim of this patch is to make two separate cpumasks for padata parallel and serial workers respectively. It allows user to make more thin and sophisticated configurations of padata framework. For example user may bind parallel and serial workers to non-intersecting CPU groups to gain better performance. Also each padata instance has notifiers chain for its cpumasks now. If either parallel or serial or both masks were changed all interested subsystems will get notification about that. It's especially useful if padata user uses algorithm for callback CPU selection according to serial cpumask.
