Macro Definition Documentation

◆ DEFAULT_MAX_UNMEASURED_BW_KB

#define DEFAULT_MAX_UNMEASURED_BW_KB   20

Default bandwidth to clip unmeasured bandwidths to using method >= MIN_METHOD_TO_CLIP_UNMEASURED_BW. (This is not a consensus method; do not get confused with the above macros.)

Definition at line 76 of file dirvote.h.

◆ MAX_BW_FILE_HEADERS_LINE_LEN

#define MAX_BW_FILE_HEADERS_LINE_LEN   1024

Maximum size of a line in a vote.

Definition at line 84 of file dirvote.h.

◆ MAX_SUPPORTED_CONSENSUS_METHOD

#define MAX_SUPPORTED_CONSENSUS_METHOD   31

The highest consensus method that we currently support.

Definition at line 56 of file dirvote.h.

◆ MIN_DIST_SECONDS

#define MIN_DIST_SECONDS   2

Lowest allowable value for DistSeconds.

Definition at line 32 of file dirvote.h.

◆ MIN_DIST_SECONDS_TESTING

#define MIN_DIST_SECONDS_TESTING   2

Lowest allowable value for DistSeconds when TestingTorNetwork is 1

Definition at line 34 of file dirvote.h.

◆ MIN_METHOD_FOR_CANONICAL_FAMILIES_IN_MICRODESCS

#define MIN_METHOD_FOR_CANONICAL_FAMILIES_IN_MICRODESCS   29

Lowest consensus method where microdescriptor lines are put in canonical form for improved compressibility and ease of storage. See proposal 298.

Definition at line 62 of file dirvote.h.

◆ MIN_METHOD_FOR_CORRECT_BWWEIGHTSCALE

#define MIN_METHOD_FOR_CORRECT_BWWEIGHTSCALE   31

Lowest consensus method for which we use the correct algorithm for extracting the bwweightscale= and maxunmeasuredbw= parameters. See #19011.

Definition at line 71 of file dirvote.h.

◆ MIN_METHOD_FOR_UNPADDED_NTOR_KEY

#define MIN_METHOD_FOR_UNPADDED_NTOR_KEY   30

Lowest consensus method where an unpadded base64 onion-key-ntor is allowed See #7869

Definition at line 66 of file dirvote.h.

◆ MIN_SUPPORTED_CONSENSUS_METHOD

#define MIN_SUPPORTED_CONSENSUS_METHOD   28

The lowest consensus method that we currently support.

Definition at line 53 of file dirvote.h.

◆ MIN_VOTE_INTERVAL

#define MIN_VOTE_INTERVAL   300

Lowest allowable voting interval.

Definition at line 37 of file dirvote.h.

◆ MIN_VOTE_INTERVAL_TESTING

#define MIN_VOTE_INTERVAL_TESTING    (((MIN_VOTE_SECONDS_TESTING)+(MIN_DIST_SECONDS_TESTING)+1)*2)

Lowest allowable voting interval when TestingTorNetwork is 1: Voting Interval can be: 10, 12, 15, 18, 20, 24, 25, 30, 36, 40, 45, 50, 60, ... Testing Initial Voting Interval can be: 5, 6, 8, 9, or any of the possible values for Voting Interval, as they both need to evenly divide 30 minutes. If clock desynchronisation is an issue, use an interval of at least: 18 * drift in seconds, to allow for a clock slop factor

Definition at line 46 of file dirvote.h.

◆ MIN_VOTE_SECONDS

#define MIN_VOTE_SECONDS   2

Lowest allowable value for VoteSeconds.

Definition at line 27 of file dirvote.h.

◆ MIN_VOTE_SECONDS_TESTING

#define MIN_VOTE_SECONDS_TESTING   2

Lowest allowable value for VoteSeconds when TestingTorNetwork is 1

Definition at line 29 of file dirvote.h.

Function Documentation

◆ dirserv_generate_networkstatus_vote_obj()

networkstatus_t* dirserv_generate_networkstatus_vote_obj ( crypto_pk_t private_key,
authority_cert_t cert 
)

Return a new networkstatus_t* containing our current opinion. (For v3 authorities)

Definition at line 4583 of file dirvote.c.

◆ dirserv_get_bandwidth_for_router_kb()

uint32_t dirserv_get_bandwidth_for_router_kb ( const routerinfo_t ri)

Get the best estimate of a router's bandwidth for dirauth purposes, preferring measured to advertised values if available.

Definition at line 4215 of file dirvote.c.

◆ dirvote_format_all_microdesc_vote_lines()

vote_microdesc_hash_t* dirvote_format_all_microdesc_vote_lines ( const routerinfo_t ri,
time_t  now,
smartlist_t microdescriptors_out 
)

Generate and return a linked list of all the lines that should appear to describe a router's microdescriptor versions in a directory vote. Add the generated microdescriptors to microdescriptors_out.

Definition at line 4018 of file dirvote.c.

◆ dirvote_get_pending_consensus()

const char* dirvote_get_pending_consensus ( consensus_flavor_t  flav)

Return the body of the consensus that we're currently trying to build.

Definition at line 3797 of file dirvote.c.

◆ dirvote_get_pending_detached_signatures()

const char* dirvote_get_pending_detached_signatures ( void  )

Return the signatures that we know for the consensus that we're currently trying to build.

Definition at line 3806 of file dirvote.c.

◆ dirvote_get_vote()

const cached_dir_t* dirvote_get_vote ( const char *  fp,
int  flags 
)

Return a given vote specified by fp. If by_id, return the vote for the authority with the v3 authority identity key digest fp; if by_id is false, return the vote whose digest is fp. If fp is NULL, return our own vote. If include_previous is false, do not consider any votes for a consensus that's already been built. If include_pending is false, do not consider any votes for the consensus that's in progress. May return NULL if we have no vote for the authority in question.

Definition at line 3820 of file dirvote.c.

◆ DIRVOTE_OPTIONAL_FLAGS

const char DIRVOTE_OPTIONAL_FLAGS[]
extern

Definition at line 4576 of file dirvote.c.

◆ DIRVOTE_UNIVERSAL_FLAGS

const char DIRVOTE_UNIVERSAL_FLAGS[]
extern

Space-separated list of all the flags that we will always vote on.

Definition at line 4564 of file dirvote.c.
