decoy_user()

ACL_USER * decoy_user	(	const LEX_CSTRING &	username,
		const LEX_CSTRING &	hostname,
		MEM_ROOT *	mem,
		struct rand_struct *	rand,
		bool	is_initialized
	)

When authentication is attempted using an unknown username a dummy user account with no authentication capabilities is assigned to the connection.

When server is started with -skip-grant-tables, a dummy user account with authentication capabilities is assigned to the connection. Dummy user authenticates with the empty authentication string. This is done to decrease the cost of enumerating user accounts based on authentication protocol.

Parameters

[in]	username	A dummy user to be created.
[in]	hostname	Host of the dummy user.
[in]	mem	Memory in which the dummy ACL user will be created.
[in]	rand	Seed value to generate random data
[in]	is_initialized	State of ACL caches

Return values

A	dummy ACL USER

deinit_rsa_keys()

void deinit_rsa_keys

(

void

)

init_rsa_keys()

bool init_rsa_keys

(

void

)

Loads the RSA key pair from disk and store them in a global variable.

init_ssl()

Returns

Error code

Return values

false	Success
true	Error

Presence of only a private key file and a public temp file implies that server crashed after creating the private key file and could not create a public key file. Hence removing the private key file.
