* crypto: algapi - enforce that all instances have a ->free() methodEric Biggers2020-01-091-0/+3
| | | | | | | | | | All instances need to have a ->free() method, but people could forget to set it and then not notice if the instance is never unregistered. To help detect this bug earlier, don't allow an instance without a ->free() method to be registered, and complain loudly if someone tries to do it.

* crypto: algapi - remove crypto_template::{alloc,free}()Eric Biggers2020-01-091-5/+0
| | | | | | | | | | Now that all templates provide a ->create() method which creates an instance, installs a strongly-typed ->free() method directly to it, and registers it, the older ->alloc() and ->free() methods in 'struct crypto_template' are no longer used. Remove them. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: algapi - pass instance to crypto_grab_spawn()Eric Biggers2020-01-091-2/+1
| | | | | | | | | | | | | Currently, crypto_spawn::inst is first used temporarily to pass the instance to crypto_grab_spawn(). Then crypto_init_spawn() overwrites it with crypto_spawn::next, which shares the same union. Finally, crypto_spawn::inst is set again when the instance is registered. Make this less convoluted by just passing the instance as an argument to crypto_grab_spawn() instead.

* crypto: aead - pass instance to crypto_grab_aead()Eric Biggers2020-01-091-2/+4
| | | | | | | | | | | | | | | | | | | | Initializing a crypto_aead_spawn currently requires: 1. Set spawn->base.inst to point to the instance. 2. Call crypto_grab_aead(). But there's no reason for these steps to be separate, and in fact this unneeded complication has caused at least one bug, the one fixed by commit 6db43410179b ("crypto: adiantum - initialize crypto_spawn::inst") So just make crypto_grab_aead() take the instance as an argument. To keep the function calls from getting too unwieldy due to this extra argument, also introduce a 'mask' variable into the affected places which weren't already using one.

* crypto: aead - Split out geniv into its own moduleHerbert Xu2019-11-171-163/+2
| | | | | | | | | | | | | If aead is built as a module along with cryptomgr, it creates a dependency loop due to the dependency chain aead => crypto_null => cryptomgr => aead. This is due to the presence of the AEAD geniv code. This code is not really part of the AEAD API but simply support code for IV generators such as seqiv. This patch moves the geniv code into its own module thus breaking the dependency loop. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | Return -EINVAL on an attempt to set the authsize to 0 with an auth. algorithm with a non-zero digestsize (i.e. anything but digest_null) as authenticating the data and then throwing away the result does not make any sense at all.

| * crypto: aead - un-inline encrypt and decrypt functionsEric Biggers2019-06-131-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | crypto_aead_encrypt() and crypto_aead_decrypt() have grown to be more than a single indirect function call. They now also check whether a key has been set, the decryption side checks whether the input is at least as long as the authentication tag length, and with CONFIG_CRYPTO_STATS=y they also update the crypto statistics. That can add up to a lot of bloat at every call site. Moreover, these always involve a function call anyway, which greatly limits the benefits of inlining. So change them to be non-inline.

* crypto: aead - set CRYPTO_TFM_NEED_KEY if ->setkey() failsEric Biggers2019-01-181-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Some algorithms have a ->setkey() method that is not atomic, in the sense that setting a key can fail after changes were already made to the tfm context. In this case, if a key was already set the tfm can end up in a state that corresponds to neither the old key nor the new key. For example, in gcm.c, if the kzalloc() fails due to lack of memory, then the CTR part of GCM will have the new key but GHASH will not. It's not feasible to make all ->setkey() methods atomic, especially ones that have to key multiple sub-tfms. Therefore, make the crypto API set CRYPTO_TFM_NEED_KEY if ->setkey() fails, to prevent the tfm from being used until a new key is set. [Cc stable mainly because when introducing the NEED_KEY flag I changed AF_ALG to rely on it; and unlike in-kernel crypto API users, AF_ALG previously didn't have this problem. So these "incompletely keyed" states became theoretically accessible via AF_ALG -- though, the opportunities for causing real mischief seem pretty limited.] Fixes: dc26c17f743a ("crypto: aead - prevent using AEADs without setting key") Cc: <stable@vger.kernel.org> # v4.16+ Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: user - clean up report structure copyingEric Biggers2018-11-091-9/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There have been a pretty ridiculous number of issues with initializing the report structures that are copied to userspace by NETLINK_CRYPTO. Commit 4473710df1f8 ("crypto: user - Prepare for CRYPTO_MAX_ALG_NAME expansion") replaced some strncpy()s with strlcpy()s, thereby introducing information leaks. Later two other people tried to replace other strncpy()s with strlcpy() too, which would have introduced even more information leaks: - https://lore.kernel.org/patchwork/patch/954991/ - https://patchwork.kernel.org/patch/10434351/ Commit cac5818c25d0 ("crypto: user - Implement a generic crypto statistics") also uses the buggy strlcpy() approach and therefore leaks uninitialized memory to userspace. A fix was proposed, but it was originally incomplete. Seeing as how apparently no one can get this right with the current approach, change all the reporting functions to: - Start by memsetting the report structure to 0. This guarantees it's always initialized, regardless of what happens later. - Initialize all strings using strscpy(). This is safe after the memset, ensures null termination of long strings, avoids unnecessary work, and avoids the -Wstringop-truncation warnings from gcc. - Use sizeof(var) instead of sizeof(type). This is more robust against copy+paste errors. For simplicity, also reuse the -EMSGSIZE return value from nla_put().

* crypto: aead - prevent using AEADs without setting keyEric Biggers2018-01-121-2/+11
| | | | | | | | | | | | | | | Similar to what was done for the hash API, update the AEAD API to track whether each transform has been keyed, and reject encryption/decryption if a key is needed but one hasn't been set. This isn't quite as important as the equivalent fix for the hash API because AEADs always require a key, so are unlikely to be used without one. Still, tracking the key will prevent accidental unkeyed use. algif_aead also had to track the key anyway, so the new flag replaces that and slightly simplifies the algif_aead implementation.

* crypto: Replaced gcc specific attributes with macros from compiler.hGideon Israel Dsouza2017-01-131-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | Continuing from this commit: 52f5684c8e1e ("kernel: use macros from compiler.h instead of __attribute__((...))") I submitted 4 total patches. They are part of task I've taken up to increase compiler portability in the kernel. I've cleaned up the subsystems under /kernel /mm /block and /security, this patch targets /crypto. There is <linux/compiler.h> which provides macros for various gcc specific constructs. Eg: __weak for __attribute__((weak)). I've cleaned all instances of gcc specific attributes with the right macros for the crypto subsystem. I had to make one additional change into compiler-gcc.h for the case when one wants to use this: __attribute__((aligned) and not specify an alignment factor. From the gcc docs, this will result in the largest alignment for that data type on the target machine so I've named the macro __aligned_largest. Please advise if another name is more appropriate.

* crypto: seqiv - Add support for new AEAD interfaceHerbert Xu2015-05-221-37/+63
| | | | | | | | | | | | | | | | | | | | This patch converts the seqiv IV generator to work with the new AEAD interface where IV generators are just normal AEAD algorithms. Full backwards compatibility is paramount at this point since no users have yet switched over to the new interface. Nor can they switch to the new interface until IV generation is fully supported by it. So this means we are adding two versions of seqiv alongside the existing one. The first one is the one that will be used when the underlying AEAD algorithm has switched over to the new AEAD interface. The second one handles the current case where the underlying AEAD algorithm still uses the old interface. Both versions export themselves through the new AEAD interface.

* crypto: aead - Add new interface with single SG listHerbert Xu2015-05-221-2/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | The primary user of AEAD, IPsec includes the IV in the AD in most cases, except where it is implicitly authenticated by the underlying algorithm. The way it is currently implemented is a hack because we pass the data in piecemeal and the underlying algorithms try to stitch them back up into one piece. This is why this patch is adding a new interface that allows a single SG list to be passed in that contains everything so the algorithm implementors do not have to stitch. The new interface accepts a single source SG list and a single destination SG list. Both must be laid out as follows: AD, skipped data, plain/cipher text, ICV The ICV is not present from the source during encryption and from the destination during decryption. For the top-level IPsec AEAD algorithm the plain/cipher text will contain the generated (or received) IV. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | | | | | | | | | | Three errors resulting in kernel memory disclosure: 1/ The structures used for the netlink based crypto algorithm report API are located on the stack. As snprintf() does not fill the remainder of the buffer with null bytes, those stack bytes will be disclosed to users of the API. Switch to strncpy() to fix this. 2/ crypto_report_one() does not initialize all field of struct crypto_user_alg. Fix this to fix the heap info leak. 3/ For the module name we should copy only as many bytes as module_name() returns -- not as much as the destination buffer could hold. But the current code does not and therefore copies random data from behind the end of the module name, as the module name is always shorter than CRYPTO_MAX_ALG_NAME. Also switch to use strncpy() to copy the algorithm's name and driver_name. They are strings, after all.

* crypto: aead - Avoid infinite loop when nivaead fails selftestHerbert Xu2009-02-181-0/+16
| | | | | | | | | | | | | | | | | | | When an aead constructed through crypto_nivaead_default fails its selftest, we'll loop forever trying to construct new aead objects but failing because it already exists. The crux of the issue is that once an aead fails the selftest, we'll ignore it on the next run through crypto_aead_lookup and attempt to construct a new aead. We should instead return an error to the caller if we find an an that has failed the test. This bug hasn't manifested itself yet because we don't have any test vectors for the existing nivaead algorithms. They're tested through the underlying algorithms only.
