Typedef Documentation

◆ RC_AAA_CTX

typedef struct rc_aaa_ctx_st RC_AAA_CTX

Opaque context returned by rc_aaa_ctx() after a successful request.

Captures the shared secret and the request authenticator vector (AUTH_VECTOR_LEN bytes) that were used in the last request. These can be retrieved with rc_aaa_ctx_get_secret() and rc_aaa_ctx_get_vector().

Pass NULL for the ctx argument to rc_aaa_ctx() if this information is not needed. When a context is no longer needed, free it with rc_aaa_ctx_free().

rh	a handle to parsed configuration.
ctx	if non-NULL, receives an allocated RC_AAA_CTX on success; the caller must free it with rc_aaa_ctx_free(). Pass NULL if not needed.
nas_port	the physical NAS port number to include (may be zero).
send	VALUE_PAIR list of attributes to send (e.g., PW_USER_NAME).
received	on success, receives the server's reply VALUE_PAIR list; the caller must free it with rc_avpair_free().
msg	if non-NULL, must point to a buffer of PW_MAX_MSG_SIZE bytes; will contain the concatenation of any PW_REPLY_MESSAGE attributes received.
add_nas_port	if non-zero, PW_NAS_PORT is added to the sent pairs.
request_type	one of the standard RADIUS codes (e.g., PW_ACCESS_REQUEST).

Parameters

rh	a handle to parsed configuration.
list	a VALUE_PAIR array of values; initially must be NULL.
attrid	The attribute of the pair to add (e.g., PW_USER_NAME).
pval	the value (e.g., the actual username).

Definition at line 46 of file avpair.c.

◆ rc_avpair_assign()

int rc_avpair_assign	(	VALUE_PAIR *	vp,
		void const *	pval,
		int	len )

Assigns the given value to an attribute-value pair

If the value is of type PW_TYPE_STRING it must either be a null terminated string with len set to -1, or raw data with length properly set. For PW_TYPE_DATE, PW_TYPE_INTEGER, and PW_TYPE_IPADDR an uint32_t number should be set at pval. For IPv4 addresses it should be in host byte order.

For PW_TYPE_IPV6ADDR type a 16-byte long address is expected, and for PW_TYPE_IPV6PREFIX the rfc3162 prefix format is expected. Simply that is a zero byte, a byte with the value of prefix (e.g., 112), and the remaining bytes are the IPv6 address.

Parameters

vp	a pointer to a VALUE_PAIR structure.
pval	the value (e.g., the actual username).
len	the length of pval, or -1 if to calculate (in case of strings).

Returns: 0 on success or -1 on failure.

◆ rc_avpair_gen()

VALUE_PAIR * rc_avpair_gen	(	rc_handle const *	rh,
		VALUE_PAIR *	pair,
		unsigned char const *	ptr,
		int	length,
		uint32_t	vendorspec )

Decode a raw RADIUS attribute buffer into a VALUE_PAIR list

Note: This is a low-level function retained for ABI compatibility with freeradius-client and radiusclient-ng. Application code should not call it directly; build requests with rc_avpair_add() and send them with rc_auth() or rc_acct(), which handle wire encoding and decoding internally.

Decodes the attribute/value region of a received RADIUS packet (the bytes that follow the 20-byte fixed header) into a linked list of VALUE_PAIR structures. Unknown attributes are logged and skipped; they are not a hard error.

Parameters

rh	a handle to parsed configuration (used for dictionary lookups).
pair	optional existing VALUE_PAIR list to append decoded attributes to; pass NULL to start a fresh list.
ptr	pointer to the start of the attribute data region.
length	number of bytes in the attribute region.
vendorspec	vendor PEN when decoding a vendor-specific sub-attribute block; pass 0 for top-level packet attributes.

Returns: head of the (possibly extended) VALUE_PAIR list, or NULL on a hard decode error (malformed length field, allocation failure).

Definition at line 1114 of file config.c.

◆ rc_config_init()

rc_handle * rc_config_init ( rc_handle * rh )

Initialise a configuration structure for programmatic configuration

Use this when you want to configure radcli from code rather than from a file. The full call sequence is:

rc_handle *rh = rc_new();
rh = rc_config_init(rh);
rc_add_config(rh, "authserver", "radius.example.com:1812:sharedsecret",
              __FILE__, __LINE__);
rc_add_config(rh, "serv-type", "udp", __FILE__, __LINE__);
rc_apply_config(rh);
// rh is now ready for rc_auth() / rc_acct()

The provided handle must have been allocated with rc_new(). Call rc_apply_config() after all rc_add_config() calls to activate the configuration and initialise the transport.

Parameters

rh	a handle allocated by rc_new().

Returns: rh on success, NULL on failure (rh is freed on failure).

Definition at line 362 of file config.c.

◆ rc_destroy()

void rc_destroy ( rc_handle * rh )

Destroys Radius Client handle reclaiming all memory

Parameters

rh	The Radius client handle to free.

Definition at line 56 of file sendserver.c.

◆ rc_read_config()

rc_handle * rc_read_config ( char const * filename )

Read the global config file

This is the primary way to initialise radcli. Loads the configuration file, initialises the transport (including TLS/DTLS handshake when applicable), and returns an opaque handle for use in subsequent calls. The format is compatible with radiusclient-ng and freeradius-client.

Standard RFC 2865/2866/2869 attributes are built into the library; the dictionary option is only needed for vendor-specific attributes.

Recognised configuration options:

Server address:

authserver: authentication server; format is host[:port[:secret]] (may be repeated for failover, comma-separated).
acctserver: accounting server; same format as authserver.

Transport:

serv-type: one of udp (default), tcp, tls, dtls.
namespace: Linux network namespace name to use for socket operations.

TLS/DTLS credentials (required when serv-type is tls or dtls):

tls-ca-file: PEM file of the CA certificate used to verify the server.
tls-cert-file: PEM file of the client certificate.
tls-key-file: PEM file of the client private key.
tls-verify-hostname: set to false to skip server hostname verification (not recommended).

Security:

require-message-authenticator: set to no to accept responses that lack the Message-Authenticator attribute. Enabled by default per draft-ietf-radext-deprecating-radius (CVE-2024-3596 / BLAST RADIUS); only disable for legacy servers that predate RFC 3579.

Tuning:

radius_timeout: request timeout in seconds (integer, default 3).
radius_retries: number of retries per server (integer, default 3).
nas-ip: source IP address to bind to when sending requests.
nas-identifier: NAS-Identifier string sent in requests.
dictionary: path to an additional attribute dictionary file.
clientdebug: debug verbosity level (integer; 0 = off).

Parameters

filename path to the configuration file.

Returns: new rc_handle on success, NULL on failure.

Examples: radexample.c.

Definition at line 618 of file config.c.

◆ rc_read_dictionary()

Definition at line 472 of file dict.c.

◆ rc_read_dictionary_from_buffer()

int rc_read_dictionary_from_buffer	(	rc_handle *	rh,
		char const *	buf,
		size_t	size )

		char *	msg,
		rc_type	type )

Sends a request to a RADIUS server and waits for the reply
