Header file containing denial of service defenses for the HS subsystem for all versions.

Function Documentation

◆ hs_dos_can_send_intro2()

bool hs_dos_can_send_intro2 ( or_circuit_t * s_intro_circ )

Return true iff an INTRODUCE2 cell can be sent on the given service introduction circuit.

◆ hs_dos_consensus_has_changed()

void hs_dos_consensus_has_changed ( const networkstatus_t * ns )

Called when the consensus has changed. We might have new consensus parameters to look at.

Definition at line 153 of file hs_dos.c.

◆ hs_dos_get_intro2_rejected_count()

uint64_t hs_dos_get_intro2_rejected_count ( void )

Return rolling count of rejected INTRO2.

◆ hs_dos_init()

void hs_dos_init ( void )

Initialize the onion service Denial of Service subsystem.

◆ hs_dos_setup_default_intro2_defenses()

void hs_dos_setup_default_intro2_defenses ( or_circuit_t * circ )

Initialize the INTRODUCE2 token bucket for the DoS defenses using the consensus/default values. We might get a cell extension that changes those later but if we don't, the default or consensus parameters are used.
