2013-02-19Refactor storing of measured_bw versus Unmeasured=1.Nick Mathewson
This patch moves the measured_bw field and the has_measured_bw field into vote_routerstatus_t, since only votes have 'Measured=XX' set on their weight line. I also added a new bw_is_unmeasured flag to routerstatus_t to represent the Unmeasured=1 flag on a w line. Previously, I was using has_measured_bw for this, which was quite incorrect: has_measured_bw means that the measured_bw field is set, and it's probably a mistake to have it serve double duty as meaning that 'baandwidth' represents a measured value. While making this change,I also found a harmless but stupid bug in dirserv_read_measured_bandwidths: It assumes that it's getting a smartlist of routerstatus_t, when really it's getting a smartlist of vote_routerstatus_t. C's struct layout rules mean that we could never actually get an error because of that, but it's still quite incorrect. I fixed that, and in the process needed to add two more sorting and searching helpers. Finally, I made the Unmeasured=1 flag get parsed. We don't use it for anything yet, but someday we might. This isn't complete yet -- the new 2286 unit test doesn't build.

2013-02-19Tweak consensus method 17 based on arma's commentsNick Mathewson
Instead of capping whenever a router has fewer than 3 measurements, we cap whenever a router has fewer than 3 measurements *AND* there are at least 3 authorities publishing measured bandwidths. We also generate bandwidth lines with a new "Unmeasured=1" flag, meaning that we didn't have enough observations for a node to use measured bandwidth values in the authority's input, whether we capped it or not.

One is a probably-impossible leak if we fail to sign a consensus; another occurs when we can't look up the user we're trying to chown our sockets to.

2013-02-05New consensus method: clip the maximum votable unmeasured bwNick Mathewson
If we're deciding on a node's bandwidth based on "Bandwidth=" declarations, clip it to "20" or to the maxunmeasuredbw parameter, if it's voted on. This adds a new consensus method. This is "part A" of bug 2286

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;

2012-11-14Better policy support for IPv6Nick Mathewson
Now, "accept *:80" means "accept all addresses on port 80", and not just IPv4. For just v4, say "accept *4:80"; for just v6 say "accept *6:80". We can parse these policies from torrc just fine, and we should be successfully keeping them out of descriptors for now. We also now include appropriate IPv6 addresses in "reject private:*"
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. (That is, all the C except that in src/ext.)

2012-10-10Use fmt_addrport where appropriate.David Fifield
This is mostly a conversion from this pattern: log("... %s:%d ...", fmt_and_decorate_addr(&addr), port); to this: log("... %s ...", fmt_addrport(&addr, port)); The output is the same in all cases.

Harmless unless we somehow generate a microdesc of more than INT_MAX bytes.

2012-09-04Generate microdescriptors with "a" lines.Linus Nordberg
Generate and store all supported microdescriptor formats. Generate votes with one "m" line for each format. Only "m" lines with version info matching chosen consensus method will be voted upon. An optimisation would be to combine "m" lines with identical hashes, i.e. instead of "m 1,2,3 H1" and "m 4,5 H1", say "m 1,2,3,4,5 H1".
2012-09-04Have directory authorities vote on IPv6 OR ports according to the specLinus Nordberg
Define new new consensus method 14 adding "a" lines to vote and consensus documents. From proposal 186: As with other data in the vote derived from the descriptor, the consensus will include whichever set of "a" lines are given by the most authorities who voted for the descriptor digest that will be used for the router. This patch implements this.

2012-08-01Defensive programming: clear rs_out between iterations.Nick Mathewson
I can't currently find a bug here, but there are a couple of near-misses. Addresses ticket 6514; reported pseudonymously on IRC.
2012-07-31Remove the upper limit on the size of MD we can generate.Nick Mathewson
2012-07-31Don't include a router in an md consensus if we can't find a md for it.Nick Mathewson
The spec requires that every router in a microdesc consensus have an m line; we weren't obeying that spec. This creates a new consensus method (13) to allow voting to continue to work right. Partial fix for bug 6404; fix on 0.2.2.6-alpha.

2012-07-17Change all SMARTLIST_FOREACH loops of >=10 lines to use BEGIN/ENDNick Mathewson
The SMARTLIST_FOREACH macro is more convenient than BEGIN/END when you have a nice short loop body, but using it for long bodies makes your preprocessor tell the compiler that all the code is on the same line. That causes grief, since compiler warnings and debugger lines will all refer to that one line. So, here's a new style rule: SMARTLIST_FOREACH blocks need to be short.

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.
2012-05-07Detect out-of-bounds bwweightscale values early in the voting processNick Mathewson
If the authorities agreed on a sufficiently bad bwweightscale value (<=0 or == INT32_MAX), the bandwidth algorithm could make the voters assert while computing the consensus. Fix for bug5786; bugfix on 0.2.2.17-alpha

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.)
