* [CRYPTO] padlock: Driver for SHA1 / SHA256 algorithmsMichal Ludvig2006-09-20
| | | | | | | Support for SHA1 / SHA256 algorithms in VIA C7 processors. Signed-off-by: Michal Ludvig <michal@logix.cz> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] padlock: Update private header fileMichal Ludvig2006-09-20
| | | | | | | | | | | PADLOCK_CRA_PRIORITY is shared between padlock-aes and padlock-sha so it should be in the header. On the other hand "struct cword" is only used in padlock-aes.c so it's unnecessary to have it in padlock.h Signed-off-by: Michal Ludvig <michal@logix.cz> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] padlock: Add compatibility alias after renameHerbert Xu2006-09-20
| | | | | | | | | | Whenever we rename modules we should add an alias to ensure that existing users can still locate the new module. This patch also gets rid of the now unused module function prototypes from padlock.h. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] padlock: Get rid of padlock-generic.cMichal Ludvig2006-09-20
| | | | | | | | | | Merge padlock-generic.c into padlock-aes.c and compile AES as a standalone module. We won't make a monolithic padlock.ko with all supported algorithms, instead we'll compile each driver into its own module.

* [CRYPTO] sha: Add module aliases for sha1 / sha256Michal Ludvig2006-09-20
| | | | | | | | | | Crypto modules should be loadable by their .cra_driver_name, so we should make MODULE_ALIAS()es with these names. This patch adds aliases for SHA1 and SHA256 only as that's what we need for PadLock-SHA driver. Signed-off-by: Michal Ludvig <michal@logix.cz> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] api: Added spawnsHerbert Xu2006-09-20
| | | | | | | | | | Spawns lock a specific crypto algorithm in place. They can then be used with crypto_spawn_tfm to allocate a tfm for that algorithm. When the base algorithm of a spawn is deregistered, all its spawns will be automatically removed. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [CRYPTO] api: Allow algorithm lookup by typeHerbert Xu2006-09-20
| | | | | | | | | | | This patch also adds the infrastructure to pick an algorithm based on their type. For example, this allows you to select the encryption algorithm "aes", instead of any algorithm registered under the name "aes". For now this is only accessible internally. Eventually it will be made available through crypto_alloc_tfm. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [CRYPTO] api: Add cryptomgrHerbert Xu2006-09-20
| | | | | | | | | | | | | | The cryptomgr module is a simple manager of crypto algorithm instances. It ensures that parameterised algorithms of the type tmpl(alg) (e.g., cbc(aes)) are always created. This is meant to satisfy the needs for most users. For more complex cases such as deeper combinations or multiple parameters, a netlink module will be created which allows arbitrary expressions to be parsed in user-space.

* [CRYPTO] api: Added event notificationHerbert Xu2006-09-20
| | | | | | | | | This patch adds a notifier chain for algorithm/template registration events. This will be used to register compound algorithms such as cbc(aes). In future this will also be passed onto user-space through netlink. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [CRYPTO] api: Add template registrationHerbert Xu2006-09-20
| | | | | | | | | A crypto_template generates a crypto_alg object when given a set of parameters. this patch adds the basic data structure fo templates and code to handle their registration/deregistration.

* [CRYPTO] api: Split out low-level APIHerbert Xu2006-09-20
| | | | | | | | | | The crypto API is made up of the part facing users such as IPsec and the low-level part which is used by cryptographic entities such as algorithms. This patch splits out the latter so that the two APIs are more clearly delineated. As a bonus the low-level API can now be modularised if all algorithms are built as modules. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [IPSEC]: Move linux/crypto.h inclusion out of net/xfrm.hHerbert Xu2006-09-20
| | | | | | | | | The header file linux/crypto.h is only needed by a few files so including it in net/xfrm.h (which is included by half of the networking stack) is a waste. This patch moves it out of net/xfrm.h and into the specific header files that actually need it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] api: Add crypto_alg reference countingHerbert Xu2006-09-20
| | | | | | | | | | | | | Up until now we've relied on module reference counting to ensure that the crypto_alg structures don't disappear from under us. This was good enough as long as each crypto_alg came from exactly one module. However, with parameterised crypto algorithms a crypto_alg object may need two or more modules to operate. This means that we need to count the references to the crypto_alg object directly. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [CRYPTO] api: Rename crypto_alg_get to crypto_mod_getHerbert Xu2006-09-20
| | | | | | | | | | | | | The functions crypto_alg_get and crypto_alg_put operates on the crypto modules rather than the algorithms. Therefore it makes sense to call them crypto_mod_get and crypto_alg_put respectively. This is needed because we need to have real algorithm reference counters for parameterised algorithms as they can be unregistered from below by when their parameter algorithms are themselves unregistered.

It also creates a new header file which will be used by all 3 modules. This eliminates all code duplication. Correctness was verified with the tcrypt module and automated test scripts.

* [CRYPTO] api: Fixed crypto_tfm context alignmentHerbert Xu2006-09-20
| | | | | | | | | | | Previously the __aligned__ attribute was added to the crypto_tfm context member to ensure it is alinged correctly on architectures such as arm. Unfortunately kmalloc does not use the same minimum alignment rules as gcc so this is useless. This patch changes it to use kmalloc's minimum alignment.

* | Revert mmiocfg heuristics and blacklist changesLinus Torvalds2006-09-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commits 11012d419cfc0e0f78ca356aca03674217910124 and 40dd2d20f220eda1cd0da8ea3f0f9db8971ba237, which allowed us to use the MMIO accesses for PCI config cycles even without the area being marked reserved in the e820 memory tables. Those changes were needed for EFI-environment Intel macs, but broke some newer Intel 965 boards, so for now it's better to revert to our old 2.6.17 behaviour and at least avoid introducing any new breakage. Andi Kleen has a set of patches that work with both EFI and the broken Intel 965 boards, which will be applied once they get wider testing.

This patch implements both ->lock() and ->unlock() and provides a fixup to install them when an AT49BV6416 chip is detected. These functions are probably valid on more Atmel chips, but I believe it's mostly obsolete ones. The AT49BV6416 is in fact obsolete, but it's used on all current AT32STK1000 development boards.

This patch only saves the option string at the early boot stage, and parses them later when block2mtd_init() is called. If open_bdev_excl() fails, open_by_devnum(name_to_dev_t()) is tried instead, which makes it possible to initialize the driver before rootfs has been mounted. Also gets rid of the superfluous parse_name() that only checks if name is longer than 80 chars and copies it to a string that is not kfreed. With this patch, I can boot statically compiled block2mtd, and mount jffs2 as rootfs (without modules or initrd), with lilo config like this: root=/dev/mtdblock0 append="rootfstype=jffs2 block2mtd.block2mtd=/dev/hdc2,65536" (Note that rootfstype=jffs2 is required, since the kernel only tries filesystems without "nodev" attribute by default, and jffs is "nodev"). Compared to first version of this patch, this one does not copy the parameters to the global buffer if init has already been called, and the global array is marked as __initdata. Compared to the second version of this patch, module build is fixed. Compared to the third version of this patch, statically compiled block2mtd driver with no boot-time parameter no longer gives spurious error 'cannot open device ""' Signed-off-by: Ville Herva <vherva@vianova.fi> Acked-by: Jörn Engel <joern@wohnheim.fh-wedel.de> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

(30% degradation running dbench with 16 threads) Commit 21730eed11de42f22afcbd43f450a1872a0b5ea1, which claims to make EXT2_DEBUG work again, moves the taking of the kernel lock out of debug-only code in ext2_count_free_inodes and ext2_count_free_blocks and into ext2_statfs. The same problem was fixed in ext3 by removing the lock completely (commit 5b11687924e40790deb0d5f959247ade82196665) Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
