* proc: introduce proc_create_seq{,_data}Christoph Hellwig2018-05-161-13/+1
| | | | | | | | | Variants of proc_create{,_data} that directly take a struct seq_operations argument and drastically reduces the boilerplate code in the callers. All trivial callers converted over. Signed-off-by: Christoph Hellwig <hch@lst.de>
* crypto: algapi - convert cra_refcnt to refcount_tEric Biggers2018-01-051-1/+1
| | | | | | | | | | | Reference counters should use refcount_t rather than atomic_t, since the refcount_t implementation can prevent overflows, reducing the exploitability of reference leak bugs. crypto_alg.cra_refcount is a reference counter with the usual semantics, so switch it over to refcount_t.

* crypto: fips - Move fips_enabled sysctl into fips.cHerbert Xu2015-04-231-41/+0
| | | | | | | | | | | | There is currently a large ifdef FIPS code section in proc.c. Ostensibly it's there because the fips_enabled sysctl sits under /proc/sys/crypto. However, no other crypto sysctls exist. In fact, the whole ethos of the crypto API is against such user interfaces so this patch moves all the FIPS sysctl code over to fips.c.

* crypto: proc - identify internal ciphersStephan Mueller2015-03-311-0/+3
| | | | | | | | | | With ciphers that now cannot be accessed via the kernel crypto API, callers shall be able to identify the ciphers that are not callable. The /proc/crypto file is added a boolean field identifying that such internal ciphers. Signed-off-by: Stephan Mueller <smueller@chronox.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | | | | | | | For consistency drop & in front of every proc_handler. Explicity taking the address is unnecessary and it prevents optimizations like stubbing the proc_handlers to NULL.

* crypto: api - Call type show function before legacy for procHerbert Xu2008-12-251-7/+13
| | | | | | | | | | This patch makes /proc/crypto call the type-specific show function if one is present before calling the legacy show functions for cipher/digest/compress. This allows us to reuse the type values for those legacy types. In particular, hash and digest will share one type value while shash is phased in as the default hash type.

* crypto: api - Add fips_enable flagNeil Horman2008-08-291-0/+47
| | | | | | | | | | | | | | | Add the ability to turn FIPS-compliant mode on or off at boot In order to be FIPS compliant, several check may need to be preformed that may be construed as unusefull in a non-compliant mode. This patch allows us to set a kernel flag incating that we are running in a fips-compliant mode from boot up. It also exports that mode information to user space via a sysctl (/proc/sys/crypto/fips_enabled). Tested successfully by me.

* [PATCH] mark struct file_operations const 3Arjan van de Ven2007-02-121-1/+1
| | | | | | | | | | | Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

* [CRYPTO] api: Added crypto_type supportHerbert Xu2006-09-211-1/+4
| | | | | | | | | | | 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.

* [CRYPTO] api: Split out low-level APIHerbert Xu2006-09-211-0/+5
| | | | | | | | | | 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>
* [CRYPTO] api: Add crypto_alg reference countingHerbert Xu2006-09-211-0/+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>
* [CRYPTO] Allow multiple implementations of the same algorithmHerbert Xu2006-01-091-3/+3
| | | | | | | | | | | | | | | | | | | | | | This is the first step on the road towards asynchronous support in the Crypto API. It adds support for having multiple crypto_alg objects for the same algorithm registered in the system. For example, each device driver would register a crypto_alg object for each algorithm that it supports. While at the same time the user may load software implementations of those same algorithms. Users of the Crypto API may then select a specific implementation by name, or choose any implementation for a given algorithm with the highest priority. The priority field is a 32-bit signed integer. In future it will be possible to modify it from user-space. This also provides a solution to the problem of selecting amongst various AES implementations, that is, aes vs. aes-i586 vs. aes-padlock.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+112
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
