crypto: ecdh - move curve_id of ECDH from the key to algorithm name

2021-03-12T13:04:03+00:00

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.

Bluetooth: Remove CRYPTO_ALG_INTERNAL flag

2020-07-31T13:42:04+00:00

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 Signed-off-by: Johan Hedberg

Bluetooth: Fix compiler warning with selftest duration calculation

Bluetooth: let the crypto subsystem generate the ecc privkey

2017-10-06T18:35:47+00:00

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.

Bluetooth: move ecdh allocation outside of ecdh_helper

2017-10-06T18:35:47+00:00

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 Signed-off-by: Marcel Holtmann

Bluetooth: kfree tmp rather than an alias to it

2017-08-11T19:19:46+00:00

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. Detected by CoverityScan, CID#1448650 ("Free of address-of expression") Signed-off-by: Colin Ian King Signed-off-by: Marcel Holtmann

Bluetooth: allocate data for kpp on heap

2017-04-30T10:22:05+00:00

Bluetooth would crash when computing ECDH keys with kpp if VMAP_STACK is enabled. Fix by allocating data passed to kpp on heap. Fixes: 58771c1c ("Bluetooth: convert smp and selftest to crypto kpp API") Signed-off-by: Salvatore Benedetto Signed-off-by: Marcel Holtmann

Bluetooth: convert smp and selftest to crypto kpp API

2017-04-25T02:53:42+00:00

* 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. Signed-off-by: Salvatore Benedetto Signed-off-by: Marcel Holtmann

Bluetooth: Export ECDH selftest result in debugfs

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 Signed-off-by: Johan Hedberg
