CONFIG_CRYPTO_STATS: Crypto usage statistics

General informations

The Linux kernel configuration item CONFIG_CRYPTO_STATS has multiple definitions:

Crypto usage statistics found in crypto/Kconfig

The configuration item CONFIG_CRYPTO_STATS:

• prompt: Crypto usage statistics
• type: bool
• depends on: CONFIG_CRYPTO_USER
• defined in crypto/Kconfig
• found in Linux kernels: 6.1–6.6, 6.7-rc+HEAD

Help text

Enable the gathering of crypto stats.

Enabling this option reduces the performance of the crypto API. It should only be enabled when there is actually a use case for it.

This collects data sizes, numbers of requests, and numbers of errors processed by: - AEAD ciphers (encrypt, decrypt) - asymmetric key ciphers (encrypt, decrypt, verify, sign) - symmetric key ciphers (encrypt, decrypt) - compression algorithms (compress, decompress) - hash algorithms (hash) - key-agreement protocol primitives (setsecret, generate public key, compute shared secret) - RNG (generate, seed)

Crypto usage statistics for User-space found in crypto/Kconfig

The configuration item CONFIG_CRYPTO_STATS:

• prompt: Crypto usage statistics for User-space
• type: bool
• depends on: CONFIG_CRYPTO_USER
• defined in crypto/Kconfig
• found in Linux kernels: 5.0–5.19, 6.0, 6.0+HEAD

Help text

This option enables the gathering of crypto stats. This will collect: - encrypt/decrypt size and numbers of symmeric operations - compress/decompress size and numbers of compress operations - size and numbers of hash operations - encrypt/decrypt/sign/verify numbers for asymmetric operations - generate/seed numbers for rng operations

found in crypto/Kconfig

The configuration item CONFIG_CRYPTO_STATS:

• prompt:
• type: bool
• depends on: (none)
• defined in crypto/Kconfig
• found in Linux kernels: 4.20
