2008-04-21[CRYPTO] tcrypt: Change the XTEA test vectorsSebastian Siewior1-3/+3
The third test vector of ECB-XTEA-ENC fails for me all other are fine. I could not find a RFC or something else where they are defined. The test vector has not been modified since git started recording histrory. The implementation is very close (not to say equal) to what is available as Public Domain (they recommend 64 rounds and the in kernel uses 32). Therefore I belive that there is typo somewhere and tcrypt reported always *fail* instead of *okey*. This patch replaces input + result of the third test vector with result + input from the third decryption vector. The key is the same, the other three test vectors are also the reverse.

2008-04-21[CRYPTO] tcrypt: Shrink the tcrypt moduleSebastian Siewior1-5773/+5770
Currently the tcrypt module is about 2 MiB on x86-32. The main reason for the huge size is the data segment which contains all the test vectors for each algorithm. The test vectors are staticly allocated in an array and the size of the array has been drastically increased by the merge of the Salsa20 test vectors. With a hint from Benedigt Spranger I found a way how I could convert those fixed-length arrays to strings which are flexible in size. VIM and regex were also very helpfull :) So, I am talking about a shrinking of ~97% on x86-32: text data bss dec hex filename 18309 2039708 20 2058037 1f6735 tcrypt-b4.ko 45628 23516 80 69224 10e68 tcrypt.ko Signed-off-by: Sebastian Siewior <sebastian@breakpoint.cc> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2008-04-21[CRYPTO] tcrypt: Change the usage of the test vectorsSebastian Siewior1-165/+181
The test routines (test_{cipher,hash,aead}) are makeing a copy of the test template and are processing the encryption process in place. This patch changes the creation of the copy so it will work even if the source address of the input data isn't an array inside of the template but a pointer.

2008-04-19Security: Introduce security= boot parameterAhmed S. Darwish8-4/+83
Add the security= boot parameter. This is done to avoid LSM registration clashes in case of more than one bult-in module. User can choose a security module to enable at boot. If no security= boot parameter is specified, only the first LSM asking for registration will be loaded. An invalid security module name will be treated as if no module has been chosen. LSM modules must check now if they are allowed to register by calling security_module_enable(ops) first. Modify SELinux and SMACK to do so. Do not let SMACK register smackfs if it was not chosen on boot. Smackfs assumes that smack hooks are registered and the initial task security setup (swapper->security) is done.

2008-04-18[NET]: Fix and allocate less memory for ->priv'less netdevicesAlexey Dobriyan1-6/+9
This patch effectively reverts commit d0498d9ae1a5cebac363e38907266d5cd2eedf89 aka "[NET]: Do not allocate unneeded memory for dev->priv alignment." It was found to be buggy because of final unconditional += NETDEV_ALIGN_CONST removal. For example, for sizeof(struct net_device) being 2048 bytes, "alloc_size" was also 2048 bytes, but allocator with debugging options turned on started giving out !32-byte aligned memory resulting in redzones overwrites. Patch does small optimization in ->priv'less case: bumping size to next 32-byte boundary was always done to ensure ->priv will also be aligned. But, no ->priv, no need to do that.

The kernel now panics reliably on boot if you have a SATAPI device connected. The problem was introduced by the libata merge trying to pull out all the SFF code into a separate module. Unfortunately, if you're a satapi device you usually need to call atapi_request_sense, which has a bare invocation of a SFF callback which is NULL on non-SFF HBAs.

2008-04-18[SCSI] bsg: no need to set BSG_F_BLOCK bit in bsg_complete_all_commandsFUJITA Tomonori1-2/+0

2008-04-18[SCSI] bsg: remove minor in struct bsg_deviceFUJITA Tomonori1-6/+4
minor in struct bsg_device is used as identifier to find the corresponding struct bsg_device_class. However, request_queuse can be used as identifier for that and the minor in struct bsg_device is unnecessary.

2008-04-18[SCSI] bsg: replace kobject_get with blk_get_queueFUJITA Tomonori1-2/+7
Both takes a ref to a queue. But blk_get_queue checks QUEUE_FLAG_DEAD and is more appropriate interface here. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
2008-04-18[SCSI] bsg: takes a ref to struct device in fops->openFUJITA Tomonori1-6/+13
bsg_register_queue() takes a ref to struct device that a caller passes. For example, bsg takes a ref to the sdev_gendev for scsi devices. However, bsg doesn't inrease the refcount in fops->open. So while an application opens a bsg device, the scsi device that the bsg device holds can go away (bsg also takes a ref to a queue, but it doesn't prevent the device from going away). With this patch, bsg increases the refcount of struct device in fops->open and decreases it in fops->release.
