Function Documentation

check_authority_cert_callback()

static int check_authority_cert_callback ( time_t  now, const or_options_t *  options  )

static

Periodic callback: if we're an authority, check on our authority certificate (the one that authenticates our authority signing key).

Definition at line 41 of file dirauth_periodic.c.

dirvote_callback()

static int dirvote_callback ( time_t  now, const or_options_t *  options  )

static

Scheduled callback: Run directory-authority voting functionality.

The schedule is a bit complicated here, so dirvote_act() manages the schedule itself.

Definition at line 61 of file dirauth_periodic.c.

downrate_stability_callback()

static int downrate_stability_callback ( time_t  now, const or_options_t *  options  )

static

Periodic callback: if we're an authority, discount the stability information (and other rephist information) that's older.

Definition at line 130 of file dirauth_periodic.c.

launch_reachability_tests_callback()

static int launch_reachability_tests_callback ( time_t  now, const or_options_t *  options  )

static

Periodic callback: if we're an authority, make sure we test the routers on the network for reachability.

Definition at line 113 of file dirauth_periodic.c.

reschedule_dirvote()

void reschedule_dirvote

(

const or_options_t *

options

)

Reschedule the directory-authority voting event. Run this whenever the schedule has changed.

Definition at line 83 of file dirauth_periodic.c.

save_stability_callback()

static int save_stability_callback ( time_t  now, const or_options_t *  options  )

static

Periodic callback: if we're an authority, record our measured stability information from rephist in an mtbf file.

Definition at line 95 of file dirauth_periodic.c.

write_bridge_ns_callback()

static int write_bridge_ns_callback ( time_t  now, const or_options_t *  options  )

static

Periodic callback: if we're the bridge authority, write a networkstatus file to disk.
