2017-11-27relay: Change bandwidth stats interval to 24 hoursDavid Goulet
Going from 4 hours to 24 hours in order to try reduce the efficiency of guard discovery attacks. Closes #23856 Signed-off-by: David Goulet <dgoulet@torproject.org>
2014-12-22Increase bandwidth usage report interval to 4 hours.Nick Mathewson
2014-09-02Fix a number of clang analyzer false-positivesNick Mathewson
Most of these are in somewhat non-obvious code where it is probably a good idea to initialize variables and add extra assertions anyway. Closes 13036. Patches from "teor".
2014-05-11Quench clang's complaints with -Wshorten-64-to-32 when time_t is not long.dana koch
On OpenBSD 5.4, time_t is a 32-bit integer. These instances contain implicit treatment of long and time_t as comparable types, so explicitly cast to time_t.
2014-05-05Remove /tor/dbg-stability.txt URL.Karsten Loesing
The /tor/dbg-stability.txt URL was meant to help debug WFU and MTBF calculations, but nobody was using it. Fixes #11742.
2014-04-15Uplift status.c unit test coverage with new test cases and macros.dana koch
A new set of unit test cases are provided, as well as introducing an alternative paradigm and macros to support it. Primarily, each test case is given its own namespace, in order to isolate tests from each other. We do this by in the usual fashion, by appending module and submodule names to our symbols. New macros assist by reducing friction for this and other tasks, like overriding a function in the global namespace with one in the current namespace, or declaring integer variables to assist tracking how many times a mock has been called. A set of tests for a small-scale module has been included in this commit, in order to highlight how the paradigm can be used. This suite gives 100% coverage to status.c in test execution.
2014-03-27Renamed "onionskins_completed" to "onionskins_assigned"Nick Mathewson
This improves the accuracy of the function/variable names.
2014-03-05Rename PredictedCircsRelevanceTime->PredictedPortsRelevanceTimeNick Mathewson
All circuits are predictive; it's the ports that are expiring here.

2014-03-05PredictedCircsRelevanceTime: limit how long we predict a port will be usedunixninja92
By default, after you've made a connection to port XYZ, we assume you might still want to have an exit ready to connect to XYZ for one hour. This patch lets you lower that interval. Implements ticket 91

2014-02-06Deliver circuit handshake counts as part of the heartbeatNick Mathewson
Previously, they went out once an hour, unconditionally. Fixes 10485; bugfix on 0.2.4.17-rc.
2013-12-24Merge remote-tracking branch 'public/bug10485'Nick Mathewson
2013-12-24Move onion-type stats message into heartbeatNick Mathewson
Fix for 10485. Fix on 0.2.4.17-alpha.

2013-09-05collect and log statistics about onionskins received/processedRoger Dingledine
we skip onionskins that came from non-relays, so we're less likely to run into privacy troubles. starts to implement ticket 9658.
2013-08-15Rename circuit_get_global_list to remove trailing _Nick Mathewson
2013-06-20Fix #9108 - make global_circuitlist a doubly linked listMarek Majkowski
2013-05-24Extract duplicate code in geoip and rephist.Peter Retzlaff
Create new methods check_or_create_data_subdir() and write_to_data_subdir() in config.c and use them throughout rephist.c and geoip.c. This should solve ticket #4282.
2013-02-14Authorities were adding downtime for every relay every restartRoger Dingledine
Stop marking every relay as having been down for one hour every time we restart a directory authority. These artificial downtimes were messing with our Stable and Guard flag calculations. Fixes bug 8218 (introduced by the fix for 1035). Bugfix on 0.2.2.23-alpha.
2013-02-09Wrap more macro definitions in (parentheses)Nick Mathewson
To avoid surprises, good coding practice suggests parenthesizing every macro definition -- or at the very least, all those involving an expression.
2013-02-04When we mark a node as a sybil, mark it down and reset its uptime to 0Nick Mathewson
This prevents bug 8147, where such nodes would accrue points towards Guard, Fast, HSDir, and so on. Fixes bug 8147.
2013-02-01Rename log() to tor_log() for loggingNick Mathewson
This is meant to avoid conflict with the built-in log() function in math.h. It resolves ticket 7599. First reported by dhill. This was generated with the following perl script: #!/usr/bin/perl -w -i -p s/\blog\(LOG_(ERR|WARN|NOTICE|INFO|DEBUG)\s*,\s*/log_\L$1\(/g; s/\blog\(/tor_log\(/g;

2012-10-12Rename all reserved C identifiers we definedNick Mathewson
For everything we declare that starts with _, make it end with _ instead. This is a machine-generated patch. To make it, start by getting the list of reserved identifiers using: git ls-tree -r --name-only HEAD | grep '\.[ch]$' | \ xargs ctags --c-kinds=defglmpstuvx -o - | grep '^_' | \ cut -f 1 | sort| uniq You might need gnu ctags. Then pipe the output through this script: ============================== use strict; BEGIN { print "#!/usr/bin/perl -w -i -p\n\n"; } chomp; next if ( /^__attribute__/ or /^__func__/ or /^_FILE_OFFSET_BITS/ or /^_FORTIFY_SOURCE/ or /^_GNU_SOURCE/ or /^_WIN32/ or /^_DARWIN_UNLIMITED/ or /^_FILE_OFFSET_BITS/ or /^_LARGEFILE64_SOURCE/ or /^_LFS64_LARGEFILE/ or /^__cdecl/ or /^__attribute__/ or /^__func__/ or /^_WIN32_WINNT/); my $ident = $_; my $better = $ident; $better =~ s/^_//; $better = "${better}_"; print "s/(?<![A-Za-z0-9_])$ident(?![A-Za-z0-9_])/$better/g;\n"; ============================== Then run the resulting script on all the files you want to change.

2012-10-03Free some more still-in-use memory at exitRoger Dingledine
2012-09-10Merge branch 'maint-0.2.3'Roger Dingledine
2012-09-10Avoid segfault when reading state file from ancient torNick Mathewson
If s_values is null in rep_hist_load_bwhist_state_section, we would call smartlist_len() on it, and die. Fixes bug 6801.
2012-06-28Never emit the "opt" prefix in any directory stuffNick Mathewson
Fix for bug 5124.
2012-06-28Extend tor_sscanf so it can replace sscanf in rephist.cNick Mathewson
Fixes bug 4195 and Coverity CID 448
2012-06-15Triage the XXX023 and XXX022 comments: postpone many.Nick Mathewson
2012-06-13Fix integer overflow in cell stats spotted by atagar.Karsten Loesing
Fixes #5849.
2012-06-05Merge remote-tracking branch 'public/format_doubles'Nick Mathewson
Conflicts: src/or/geoip.c
2012-06-05Resolve about 24 DOCDOCsNick Mathewson
2012-06-04Update copyright dates to 2012; add a few missing copyright statementsNick Mathewson
2012-06-04Add about 60 more DOCDOC comments to 0.2.3Nick Mathewson
Also, try to resolve some doxygen issues. First, define a magic "This is doxygen!" macro so that we take the correct branch in various #if/#else/#endifs in order to get the right documentation. Second, add in a few grouping @{ and @} entries in order to get some variables and fields to get grouped together.
2012-05-16Use %f, not %lf when formatting doublesNick Mathewson
%f is correct; %lf is only needed with scanf. Apparently, on some old BSDs, %lf is deprecated. Didn't we do this before? Yes, we did. But we only got the instances of %lf, not more complicated things like %.5lf . This patch tries to get everything. Based on a patch for 3894 by grarpamp.
2012-05-16Merge remote-tracking branch 'public/bug3296'Nick Mathewson
2012-05-15Assert that rep_hist_format_desc_stats() returns !NULL.Linus Nordberg
The guard against this is the test for start_of_served_descs_stats_interval != 0 done earlier.
2012-05-15Fix desc stats on bridge authorities that didn't serve anything.Karsten Loesing
2012-05-11When no usable exit satisfies a predicted port, stop predicting it.Nick Mathewson
Fix for bug 3296.
2012-03-28Don't try to generate stats from an empty served_descs.Linus Nordberg
2012-01-18Rename nonconformant identifiers.Nick Mathewson
Fixes bug 4893. These changes are pure mechanical, and were generated with this perl script: /usr/bin/perl -w -i.bak -p s/crypto_pk_env_t/crypto_pk_t/g; s/crypto_dh_env_t/crypto_dh_t/g; s/crypto_cipher_env_t/crypto_cipher_t/g; s/crypto_digest_env_t/crypto_digest_t/g; s/aes_free_cipher/aes_cipher_free/g; s/crypto_free_cipher_env/crypto_cipher_free/g; s/crypto_free_digest_env/crypto_digest_free/g; s/crypto_free_pk_env/crypto_pk_free/g; s/_crypto_dh_env_get_dh/_crypto_dh_get_dh/g; s/_crypto_new_pk_env_rsa/_crypto_new_pk_from_rsa/g; s/_crypto_pk_env_get_evp_pkey/_crypto_pk_get_evp_pkey/g; s/_crypto_pk_env_get_rsa/_crypto_pk_get_rsa/g; s/crypto_new_cipher_env/crypto_cipher_new/g; s/crypto_new_digest_env/crypto_digest_new/g; s/crypto_new_digest256_env/crypto_digest256_new/g; s/crypto_new_pk_env/crypto_pk_new/g; s/crypto_create_crypto_env/crypto_cipher_new/g; s/connection_create_listener/connection_listener_new/g; s/smartlist_create/smartlist_new/g; s/transport_create/transport_new/g;
2012-01-16Convert instances of tor_snprintf+strdup into tor_asprintfNick Mathewson
These were found by looking for tor_snprintf() instances that were followed closely by tor_strdup(), though I probably converted some other snprintfs as well.
2012-01-16Try to use smartlist_add_asprintf consistentlyNick Mathewson
(To ensure correctness, in every case, make sure that the temporary variable is deleted, renamed, or lowered in scope, so we can't have any bugs related to accidentally relying on the no-longer-filled variable.)
2011-10-25Avoid likely memory fragmentation from rep_hist_note_descs_servedNick Mathewson
When you're doing malloc(sizeof(int)), something may well have gone wrong. This technique is a bit abusive, but we're already relying on it working correctly in geoip.c.
2011-10-25Add percentiles to the desc stats reportingSebastian Hahn
To get a better idea what's going on on Tonga, add some code to report how often the most and least frequently fetched descriptor was fetched, as well as 25, 50, 75 percentile. Also ensure we only count bridge descriptors here.
2011-10-24Don't initialize desc stats for non-bridgedirauth nodesSebastian Hahn
Also make sure that calling rep_hist_note_desc_served() while stats aren't initialized just returns. Bug spotted by SwissTorHelp. Thanks!
2011-10-21Check for jumping clock in *format_*stats functionsSebastian Hahn
None of these were real bugs (yet), because the callers made sure everything was fine. Make it more explicit. Suggested by Nick
