* ide-disk: use ide_get_lba_addr()Bartlomiej Zolnierkiewicz2008-01-25
| | | | | | | | | | | | | | * Export ide_get_lba_addr(). * Convert idedisk_{read_native,set}_max_address() to use ide_get_lba_addr(). * Remove incorrect comment from idedisk_read_native_max_address() (noticed by Sergei). There should be no functionality changes caused by this patch. Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
* ide: add ide_tf_read() helperBartlomiej Zolnierkiewicz2008-01-25
| | | | | | | | | | | | | | | | | | | | | | | | | | * Factor out code reading taskfile registers from ide_end_drive_cmd() to the new ide_tf_read() helper. * Add IDE_TFLAG_IN_* taskfile flags to indicate the need to load particular IDE taskfile register in ide_tf_read(). * Update ide_end_drive_cmd() to set respective IDE_TFLAG_IN_* taksfile flags. * Add ide_get_lba_addr() for getting LBA sector address from taskfile struct. * Factor out code getting sector address from ide_dump_ata_status() to the new ide_dump_sector() function. * Convert ide_dump_sector() to use ide_tf_read() and ide_get_lba_addr(). * Remove no longer needed ide_read_24(). The only change in functionality caused by this patch is that ide_dump_ata_status() no longer prints "high"/"low" parts of LBA48 sector address (of course LBA48 sector address is still printed).

| | | | | | | | | | | | | | | | | | | | | * Add IDE_TFLAG_CUSTOM_HANDLER taskfile flag and use it for internal requests which require custom handlers. Check the flag in do_rw_taskfile() and set handler accordingly. * Cleanup ide_init_{specify,restore,setmult}_cmd() and rename it to ide_tf_set_{specify,restore,setmult}_cmd(). * Make {set_geometry,recal,set_multmode}_intr() static. * Remove no longer needed 'handler' field from ide_task_t. v2: * 'handler' in do_rw_taskfile() must be set to NULL initially.

* ide: remove 'tf_in_flags' field from ide_task_tBartlomiej Zolnierkiewicz2008-01-25
| | | | | | | | | | | | | | | | | | | | | | | | | | * Add IDE_TFLAG_IN_DATA taskfile flag to indicate the need of reading IDE_DATA_REG in ide_end_drive_cmd(). Set the new flag in ide_taskfile_ioctl() if ->in_flags.b.data is set. * Add IDE_TFLAG_FLAGGED_SET_IN_FLAGS taskfile flag to indicate the need of modifying ->in_flags in ide_taskfile_ioctl(). Set the new flag in flagged_taskfile() and move the code modifying ->tf_in_flags to ide_taskfile_ioctl(). While at it remove the bogus comment: ->tf_in_flags (except .b.data) have no effect on selection of registers to read. * Remove no longer needed 'tf_in_flags' field from ide_task_t.

This will allow filesystems to directly own and control all of their mount options if they so choose. This interface deals only with option identifiers and strings so it should generic enough for any LSM which may come in the future. Filesystems which pass text mount data around in the kernel (almost all of them) need not currently make use of this interface when dealing with SELinux since it will still parse those strings as it always has. I assume future LSM's would do the same. NFS is the primary FS which does not use text mount data and thus must make use of this interface. An LSM would need to implement these functions only if they had mount time options, such as selinux has context= or fscontext=. If the LSM has no mount time options they could simply not implement and let the dummy ops take care of things. An LSM other than SELinux would need to define new option numbers in security.h and any FS which decides to own there own security options would need to be patched to use this new interface for every possible LSM. This is because it was stated to me very clearly that LSM's should not attempt to understand FS mount data and the burdon to understand security should be in the FS which owns the options.

| * | [AVR32] Enable debugging only when neededHaavard Skinnemoen2008-01-25
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | Keep track of processes being debugged (including the kernel itself) and turn the OCD system on and off as appropriate. Since enabling debugging turns off some optimizations in the CPU core, this fixes the issue that enabling KProbes support or simply running a program under gdbserver will reduce system performance significantly until the next reboot. The CPU performance will still be reduced for all processes while a process is being debugged, but this is a lot better than reducing the performance forever.

| * | [CRYPTO] api: Set default CRYPTO_MINALIGN to unsigned long longHerbert Xu2008-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Thanks to David Miller for pointing out that the SLAB (or SLOB/SLUB) cache uses the alignment of unsigned long long if the architecture kmalloc/slab alignment macros are not defined. This patch changes the CRYPTO_MINALIGN so that it uses the same default value. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | [CRYPTO] api: Include sched.h for cond_resched in scatterwalk.hHerbert Xu2008-01-10
| | | | | | | | | | | | | | | | | | | | | As Andrew Morton correctly points out, we need to explicitly include sched.h as we use the function cond_resched in crypto/scatterwalk.h. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | [CRYPTO] chainiv: Avoid lock spinning where possibleHerbert Xu2008-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes chainiv avoid spinning by postponing requests on lock contention if the user allows the use of asynchronous algorithms. If a synchronous algorithm is requested then we behave as before. This should improve IPsec performance on SMP when two CPUs attempt to transmit over the same SA. Currently one of them will spin doing nothing waiting for the other CPU to finish its encryption. This patch makes it postpone the request and get on with other work. If only one CPU is transmitting for a given SA, then we will process the request synchronously as before. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | [CRYPTO] null: Add null blkcipher algorithmHerbert Xu2008-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a null blkcipher algorithm called ecb(cipher_null) for backwards compatibility. Previously the null algorithm when used by IPsec copied the data byte by byte. This new algorithm optimises that to a straight memcpy which lets us better measure inherent overheads in our IPsec code. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | [CRYPTO] aead: Create default givcipher instancesHerbert Xu2008-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes crypto_alloc_aead always return algorithms that is capable of generating their own IVs through givencrypt and givdecrypt. All existing AEAD algorithms already do. New ones must either supply their own or specify a generic IV generator with the geniv field. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | [CRYPTO] aead: Add aead_geniv_alloc/aead_geniv_freeHerbert Xu2008-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch creates the infrastructure to help the construction of IV generator templates that wrap around AEAD algorithms by adding an IV generator to them. This is useful for AEAD algorithms with no built-in IV generator or to replace their built-in generator. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | [CRYPTO] aead: Add top-level givencrypt/givdecrypt callsHerbert Xu2008-01-10
| | | | | | | | | | | | | | | | | | | | | | | | This patch finally makes the givencrypt/givdecrypt operations available to users by adding crypto_aead_givencrypt and crypto_aead_givdecrypt. A suite of helpers to allocate and fill in the request is also available. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | [CRYPTO] aead: Add givcrypt operationsHerbert Xu2008-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the underlying givcrypt operations for aead and associated support elements. The rationale is identical to that of the skcipher givcrypt operations, i.e., sometimes only the algorithm knows how the IV should be generated. A new request type aead_givcrypt_request is added which contains an embedded aead_request structure with two new elements to support this operation. The new elements are seq and giv. The seq field should contain a strictly increasing 64-bit integer which may be used by certain IV generators as an input value. The giv field will be used to store the generated IV. It does not need to obey the alignment requirements of the algorithm because it's not used during the operation. The existing iv field must still be available as it will be used to store intermediate IVs and the output IV if chaining is desired. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
