Class to hold MD5 key information.
MD5Key (uint8_t key_id,
const string& key,
const TimeVal& start_timeval,
const TimeVal& end_timeval,
XorpTimer start_timer,
XorpTimer end_timer)
| MD5Key |
inline uint8_t id ()
| id |
[const]
Get the ID associated with the key.
const char* key_data ()
| key_data |
[const]
Get pointer to key data. The data is of size KEY_BYTES.
inline uint32_t key_data_bytes ()
| key_data_bytes |
[const]
Get the size of the key data in bytes.
string key ()
| key |
[const]
const TimeVal& start_timeval ()
| start_timeval |
[const]
Get the start time of the key.
const TimeVal& end_timeval ()
| end_timeval |
[const]
bool is_persistent ()
| is_persistent |
[const]
Get indication of whether key is persistent.
void set_persistent (bool v)
| set_persistent |
Set the flag whether the key is persistent.
Parameters:
v | if true the key is persistent. |
inline bool id_matches (uint8_t o)
| id_matches |
[const]
Get whether ID matches a particular value (convenient for STL algorithms).
bool valid_at (const TimeVal& when)
| valid_at |
[const]
Get key validity status of key at a particular time.
Parameters:
when | the time to test whether the key is valid. |
void reset ()
| reset |
Reset the key for all sources.
void reset (const IPv4& src_addr)
| reset |
Reset the key for a particular source.
Parameters:
src_addr | the source address. |
bool packets_received (const IPv4& src_addr)
| packets_received |
[const]
Indicate whether valid packets have been received from a source with this key ID.
Parameters:
src_addr | the source address. |
Returns: true if a packet has been received from the source, otherwise false.
uint32_t last_seqno_recv (const IPv4& src_addr)
| last_seqno_recv |
[const]
Get last received sequence number from a source.
Parameters:
src_addr | the source address. |
Returns: last sequence number seen from the source. Value may be garbage if no packets have been received (check first with packets_received()).
void set_last_seqno_recv (const IPv4& src_addr,
uint32_t seqno)
| set_last_seqno_recv |
Set last sequence number received from a source. This method implicitly set packets received to true.
Parameters:
src_addr | the source address. |
seqno | the last sequence number received from the source. |
inline uint32_t next_seqno_out ()
| next_seqno_out |
Get next sequence number for outbound packets. The counter is automatically updated with each call of this method.
