2006-09-21[CRYPTO] users: Use crypto_comp and crypto_has_*Herbert Xu1-0/+5
This patch converts all users to use the new crypto_comp type and the crypto_has_* functions. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2006-09-21[CRYPTO] api: Add crypto_comp and crypto_has_*Herbert Xu1-6/+84

2006-09-21[CRYPTO] digest: Added user API for new hash typeHerbert Xu1-34/+138
The existing digest user interface is inadequate for support asynchronous operations. For one it doesn't return a value to indicate success or failure, nor does it take a per-operation descriptor which is essential for the issuing of requests while other requests are still outstanding. This patch is the first in a series of steps to remodel the interface for asynchronous operations. For the ease of transition the new interface will be known as "hash" while the old one will remain as "digest". This patch also changes sg_next to allow chaining.

2006-09-21[CRYPTO] api: Mark parts of cipher interface as deprecatedHerbert Xu1-12/+36
Mark the parts of the cipher interface that have been replaced by block ciphers as deprecated. Thanks to Andrew Morton for suggesting doing this before removing them completely. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2006-09-21[PATCH] scatterlist: Add const to sg_set_buf/sg_init_one pointer argumentHerbert Xu1-2/+2
This patch adds a const modifier to the buf argument of sg_set_buf and sg_init_one. This lets people call it with pointers that are const. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2006-09-21[SUNRPC] GSS: Use block ciphers where applicableHerbert Xu2-11/+12
This patch converts SUNRPC/GSS to use the new block cipher type where applicable. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2006-09-21[CRYPTO] cipher: Added block cipher typeHerbert Xu1-0/+179
This patch adds the new type of block ciphers. Unlike current cipher algorithms which operate on a single block at a time, block ciphers operate on an arbitrarily long linear area of data. As it is block-based, it will skip any data remaining at the end which cannot form a block. The block cipher has one major difference when compared to the existing block cipher implementation. The sg walking is now performed by the algorithm rather than the cipher mid-layer. This is needed for drivers that directly support sg lists. It also improves performance for all algorithms as it reduces the total number of indirect calls by one. In future the existing cipher algorithm will be converted to only have a single-block interface. This will be done after all existing users have switched over to the new block cipher type. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2006-09-21[CRYPTO] cipher: Added encrypt_one/decrypt_oneHerbert Xu1-0/+96
This patch adds two new operations for the simple cipher that encrypts or decrypts a single block at a time. This will be the main interface after the existing block operations have moved over to the new block ciphers. It also adds the crypto_cipher type which is currently only used on the new operations but will be extended to setkey as well once existing users have been converted to use block ciphers where applicable. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2006-09-21[CRYPTO] api: Added crypto_type supportHerbert Xu1-0/+3
This patch adds the crypto_type structure which will be used for all new crypto algorithm types, beginning with block ciphers. The primary purpose of this abstraction is to allow different crypto_type objects for crypto algorithms of the same type, in particular, there will be a different crypto_type objects for asynchronous algorithms. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2006-09-21[CRYPTO] api: Added crypto_alloc_baseHerbert Xu1-11/+3
Up until now all crypto transforms have been of the same type, struct crypto_tfm, regardless of whether they are ciphers, digests, or other types. As a result of that, we check the types at run-time before each crypto operation. This is rather cumbersome. We could instead use different C types for each crypto type to ensure that the correct types are used at compile time. That is, we would have crypto_cipher/crypto_digest instead of just crypto_tfm. The appropriate type would then be required for the actual operations such as crypto_digest_digest. Now that we have the type/mask fields when looking up algorithms, it is easy to request for an algorithm of the precise type that the user wants. However, crypto_alloc_tfm currently does not expose these new attributes. This patch introduces the function crypto_alloc_base which will carry these new parameters. It will be renamed to crypto_alloc_tfm once all existing users have been converted. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2006-09-21[CRYPTO] api: Added asynchronous flagHerbert Xu1-0/+1
This patch adds the asynchronous flag and changes all existing users to only look up algorithms that are synchronous. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2006-09-21[CRYPTO] cipher: Removed special IV checks for ECBHerbert Xu1-2/+0
This patch makes IV operations on ECB fail through nocrypt_iv rather than calling BUG(). This is needed to generalise CBC/ECB using the template mechanism. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2006-09-21[CRYPTO] api: Get rid of flags argument to setkeyHerbert Xu1-4/+2
Now that the tfm is passed directly to setkey instead of the ctx, we no longer need to pass the &tfm->crt_flags pointer. This patch also gets rid of a few unnecessary checks on the key length for ciphers as the cipher layer guarantees that the key length is within the bounds specified by the algorithm. Rather than testing dia_setkey every time, this patch does it only once during crypto_alloc_tfm. The redundant check from crypto_digest_setkey is also removed.

2006-09-21[CRYPTO] api: Added spawnsHerbert Xu1-0/+4
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>
2006-09-21[CRYPTO] api: Add cryptomgrHerbert Xu1-0/+9
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.

2006-09-21[CRYPTO] api: Added event notificationHerbert Xu1-1/+3
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>
2006-09-21[CRYPTO] api: Add crypto_alg reference countingHerbert Xu1-0/+3
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>
2006-09-21[CRYPTO] api: Fixed crypto_tfm context alignmentHerbert Xu1-2/+23
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.

Stop exporting it, and include it only from within the existing #ifdef __KERNEL__ part of <linux/timex.h> This fixes a 'make headers_check' failure on i386 because asm-i386/timex.h includes both asm-i386/tsc.h and asm-i386/processor.h, neither of which are exported to userspace.

We don't need any of this crap included from the user-visible part of nfs_fs.h -- remove it all. In fact, we probably don't need anything but NFS_SUPER_MAGIC to be defined; is there any need for anything else?

2006-09-10V4L/DVB (4605): Fixes an issue with V4L1 and make headers-installMauro Carvalho Chehab2-4/+1
V4L1 support should be disabled when no CONFIG_VIDEO_V4L1_COMPAT is defined, to allow checking for broken V4L2 ports. This is very important during the migration phase for V4L2 API. However, userspace apps should be capable of using both APIs, since they need to test at runtime, via VIDIOCGCAP ioctl, if V4L1 is supported. So, when __KERNEL__ is not defined, those ioctls and corresponding structs should be visible. This patch also removes the obsolete defines HAVE_V4L1 and HAVE_V4L2, that where causing some confusion, and were replaced by CONFIG_VIDEO_V4L1_COMPAT and CONFIG_VIDEO_V4L2.

2006-09-08[PATCH] NFS: large non-page-aligned direct I/O clobbers memoryTrond Myklebust2-5/+5
The logic in nfs_direct_read_schedule and nfs_direct_write_schedule can allow data->npages to be one larger than rpages. This causes a page pointer to be written beyond the end of the pagevec in nfs_read_data (or nfs_write_data). Fix this by making nfs_(read|write)_alloc() calculate the size of the pagevec array, and initialise data->npages. Also get rid of the redundant argument to nfs_commit_alloc().

2006-09-06[PATCH] prevent timespec/timeval to ktime_t overflowThomas Gleixner1-1/+6
Frank v. Waveren pointed out that on 64bit machines the timespec to ktime_t conversion might overflow. This is also true for timeval to ktime_t conversions. This breaks a "sleep inf" on 64bit machines. While a timespec/timeval with tx.sec = MAX_LONG is valid by specification the internal representation of ktime_t is based on nanoseconds. The conversion of seconds to nanoseconds overflows for seconds values >= (MAX_LONG / NSEC_PER_SEC). Check the seconds argument to the conversion and limit it to the maximum time which can be represented by ktime_t.

2006-09-01[PATCH] task delay accounting fixesShailabh Nagar2-4/+7
Cleanup allocation and freeing of tsk->delays used by delay accounting. This solves two problems reported for delay accounting: 1. oops in __delayacct_blkio_ticks http://www.uwsg.indiana.edu/hypermail/linux/kernel/0608.2/1844.html Currently tsk->delays is getting freed too early in task exit which can cause a NULL tsk->delays to get accessed via reading of /proc/<tgid>/stats. The patch fixes this problem by freeing tsk->delays closer to when task_struct itself is freed up. As a result, it also eliminates the use of tsk->delays_lock which was only being used (inadequately) to safeguard access to tsk->delays while a task was exiting. 2. Possible memory leak in kernel/delayacct.c http://www.uwsg.indiana.edu/hypermail/linux/kernel/0608.2/1389.html The patch cleans up tsk->delays allocations after a bad fork which was missing earlier. The patch has been tested to fix the problems listed above and stress tested with rapid calls to delay accounting's taskstats command interface (which is the other path that can access the same data, besides the /proc interface causing the oops above).

2006-09-01[PATCH] ZVC: Scale thresholds depending on the size of the systemChristoph Lameter1-0/+1
The ZVC counter update threshold is currently set to a fixed value of 32. This patch sets up the threshold depending on the number of processors and the sizes of the zones in the system. With the current threshold of 32, I was able to observe slight contention when more than 130-140 processors concurrently updated the counters. The contention vanished when I either increased the threshold to 64 or used Andrew's idea of overstepping the interval (see ZVC overstep patch). However, we saw contention again at 220-230 processors. So we need higher values for larger systems. But the current default is already a bit of an overkill for smaller systems. Some systems have tiny zones where precision matters. For example i386 and x86_64 have 16M DMA zones and either 900M ZONE_NORMAL or ZONE_DMA32. These are even present on SMP and NUMA systems. The patch here sets up a threshold based on the number of processors in the system and the size of the zone that these counters are used for. The threshold should grow logarithmically, so we use fls() as an easy approximation. Results of tests on a system with 1024 processors (4TB RAM) The following output is from a test allocating 1GB of memory concurrently on each processor (Forking the process. So contention on mmap_sem and the pte locks is not a factor): X MIN TYPE: CPUS WALL WALL SYS USER TOTCPU fork 1 0.552 0.552 0.540 0.012 0.552 fork 4 0.552 0.548 2.164 0.036 2.200 fork 16 0.564 0.548 8.812 0.164 8.976 fork 128 0.580 0.572 72.204 1.208 73.412 fork 256 1.300 0.660 310.400 2.160 312.560 fork 512 3.512 0.696 1526.836 4.816 1531.652 fork 1020 20.024 0.700 17243.176 6.688 17249.863 So a threshold of 32 is fine up to 128 processors. At 256 processors contention becomes a factor. Overstepping the counter (earlier patch) improves the numbers a bit: fork 4 0.552 0.548 2.164 0.040 2.204 fork 16 0.552 0.548 8.640 0.148 8.788 fork 128 0.556 0.548 69.676 0.956 70.632 fork 256 0.876 0.636 212.468 2.108 214.576 fork 512 2.276 0.672 997.324 4.260 1001.584 fork 1020 13.564 0.680 11586.436 6.088 11592.523 Still contention at 512 and 1020.

2006-08-27[PATCH] Manage jbd allocations from its own slabsBadari Pulavarty1-0/+3
JBD currently allocates commit and frozen buffers from slabs. With CONFIG_SLAB_DEBUG, its possible for an allocation to cross the page boundary causing IO problems. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=200127 So, instead of allocating these from regular slabs - manage allocation from its own slabs and disable slab debug for these slabs.

2006-08-27[PATCH] vcsa attribute bits -> ioctl(VT_GETHIFONTMASK)Samuel Thibault2-0/+2
When reading /dev/vcsa while a font with more than 256 characters is loaded, one of the attribute bits records the 9th bit of the character. But depending on the console driver (vgacon or fbcon for instance), that's bit 3 or bit 0. And there is no way for userland to know that, thus no way for userland to safely grab the screen content. So here is a (tested) patch: Add a VT_GETHIFONTMASK ioctl for knowing which bit is the 9th bit for VC text (vc_hi_font_mask field of the vc_data structure).

The bridge-netfilter code will overwrite memory if there is not headroom in the skb to save the header. This first showed up when using Xen with sky2 driver that doesn't allocate the extra space.
