2021-03-12crypto: ecdh - move curve_id of ECDH from the key to algorithm nameMeng Yu1-1/+1
1. crypto and crypto/atmel-ecc: Move curve id of ECDH from the key into the algorithm name instead in crypto and atmel-ecc, so ECDH algorithm name change form 'ecdh' to 'ecdh-nist-pxxx', and we cannot use 'curve_id' in 'struct ecdh'; 2. crypto/testmgr and net/bluetooth: Modify 'testmgr.c', 'testmgr.h' and 'net/bluetooth' to adapt the modification.

2020-07-31Bluetooth: Remove CRYPTO_ALG_INTERNAL flagHerbert Xu1-1/+1
The flag CRYPTO_ALG_INTERNAL is not meant to be used outside of the Crypto API. It isn't needed here anyway. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

2017-10-06Bluetooth: let the crypto subsystem generate the ecc privkeyTudor Ambarus1-3/+11
That Bluetooth SMP knows about the private key is pointless, since the detection of debug key usage is actually via the public key portion. With this patch, the Bluetooth SMP will stop keeping a copy of the ecdh private key and will let the crypto subsystem to generate and handle the ecdh private key, potentially benefiting of hardware ecc private key generation and retention. The loop that tries to generate a correct private key is now removed and we trust the crypto subsystem to generate a correct private key. This backup logic should be done in crypto, if really needed.

2017-10-06Bluetooth: move ecdh allocation outside of ecdh_helperTudor Ambarus1-8/+21
Before this change, a new crypto tfm was allocated, each time, for both key generation and shared secret computation. Allocate a single tfm for both cases. Signed-off-by: Tudor Ambarus <tudor.ambarus@microchip.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2017-08-11Bluetooth: kfree tmp rather than an alias to itColin Ian King1-1/+1
While the kfree of dhkey_a is of the same address of tmp, it probably is clearer and more human readable if tmp is kfree'd rather than dhkey_a.

2017-04-30Bluetooth: allocate data for kpp on heapSalvatore Benedetto1-5/+17
Bluetooth would crash when computing ECDH keys with kpp if VMAP_STACK is enabled. Fix by allocating data passed to kpp on heap.

2017-04-25Bluetooth: convert smp and selftest to crypto kpp APISalvatore Benedetto1-3/+3
* Convert both smp and selftest to crypto kpp API * Remove module ecc as no more required * Add ecdh_helper functions for wrapping kpp async calls This patch has been tested *only* with selftest, which is called on module loading.

2015-04-02Bluetooth: Export ECDH selftest result in debugfsMarcel Holtmann1-4/+31
When ECDH selftest is enabled, then besides printing the result into the kernel message buffer, also create a debugfs file that allows retrieving the same information. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2015-01-14Bluetooth: Use %llu for printing duration details of selftestsMarcel Holtmann1-1/+1
The duration variable for the selftests is unsigned long long and with that use %llu instead of %lld when printing the results. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

2014-12-30Bluetooth: Add support for self testing frameworkMarcel Holtmann1-0/+62
This add support for the Bluetooth self testing framework that allows running certain test cases of sample data to ensure correctness of its basic functionality. With this patch only the basic framework will be added. It contains the build magic that allows running this at module loading time or at late_initcall stage when built into the kernel image.
