2017-04-18Rename `write_to_buf_zlib()` to `write_to_buf_compress()`.Alexander Færøy
See https://bugs.torproject.org/21663
2017-04-17Refactor the streaming compression code.Alexander Færøy
This patch refactors our streaming compression code to allow us to extend it with non-zlib/non-gzip based compression schemas. See https://bugs.torproject.org/21663

2017-02-27Merge branch 'disable_memory_sentinels_squashed'Nick Mathewson
2017-02-27Code to disable memory sentinels for fuzzingNick Mathewson
This feature makes it possible to turn off memory sentinels (like those used for safety in buffers.c and memarea.c) when fuzzing, so that we can catch bugs that they would otherwise prevent.

2017-02-27Try to check for (and prevent) buffer size INT_MAX overflow better.Nick Mathewson
Possible fix or diagnostic for 21369.

2017-02-14fixup! Don't atoi off the end of a buffer chunk.Nick Mathewson
Use STATIC.
2017-02-14Don't atoi off the end of a buffer chunk.Nick Mathewson
Fixes bug 20894; bugfix on 0.2.0.16-alpha. We already applied a workaround for this as 20834, so no need to freak out (unless you didn't apply 20384 yet).
2016-12-19for fuzzing: Add a function to make a buf with given contentsteor
(Teor wrote the code, nick extracted it into a smaller patch.)
2016-10-17Update the buffer sentinel fix to work with our #20081 fix.Nick Mathewson
2016-10-17Merge branch 'maint-0.2.8'Nick Mathewson
2016-10-17Merge branch 'buf_sentinel_026_v2' into maint-0.2.8Nick Mathewson
2016-10-17Add a one-word sentinel value of 0x0 at the end of each buf_t chunkNick Mathewson
This helps protect against bugs where any part of a buf_t's memory is passed to a function that expects a NUL-terminated input. It also closes TROVE-2016-10-001 (aka bug 20384).
2016-10-17Write a bunch of module documentation.Nick Mathewson
This commit adds or improves the module-level documenation for: buffers.c circuitstats.c command.c connection_edge.c control.c cpuworker.c crypto_curve25519.c crypto_curve25519.h crypto_ed25519.c crypto_format.c dircollate.c dirserv.c dns.c dns_structs.h fp_pair.c geoip.c hibernate.c keypin.c ntmain.c onion.c onion_fast.c onion_ntor.c onion_tap.c periodic.c protover.c protover.h reasons.c rephist.c replaycache.c routerlist.c routerparse.c routerset.c statefile.c status.c tor_main.c workqueue.c In particular, I've tried to explain (for each documented module) what each module does, what's in it, what the big idea is, why it belongs in Tor, and who calls it. In a few cases, I've added TODO notes about refactoring opportunities. I've also renamed an argument, and fixed a few DOCDOC comments.
2016-09-13Make preferred_chunk_size avoid overflow, handle big inputs betterNick Mathewson
Also, add tests for the function. Closes 20081; bugfix on 0.2.0.16-alpha. This is a Guido Vranken issue. Thanks, Guido!

2016-08-02Remove generic_buffer_*() functions as needless.Nick Mathewson
These functions were there so that we could abstract the differences between evbuffer and buf_t. But with the bufferevent removal, this no longer serves a purpose.
2016-08-02Rename generic_buffer_set_to_copy, since generic buffers are not a thingNick Mathewson
2016-07-19Use coarse monotonic timer instead of cached monotonized libevent time.Nick Mathewson

2016-05-30Replace nearly all XXX0vv comments with smarter onesNick Mathewson
So, back long ago, XXX012 meant, "before Tor 0.1.2 is released, we had better revisit this comment and fix it!" But we have a huge pile of such comments accumulated for a large number of released versions! Not cool. So, here's what I tried to do: * 0.2.9 and 0.2.8 are retained, since those are not yet released. * XXX+ or XXX++ or XXX++++ or whatever means, "This one looks quite important!" * The others, after one-by-one examination, are downgraded to plain old XXX. Which doesn't mean they aren't a problem -- just that they cannot possibly be a release-blocking problem.

2015-09-02Remove remaining references to "nulterminate" in commentsNick Mathewson
Thanks to Roger for spotting this!
2015-09-01Remove the unused "nulterminate" option to buf_pullup()Nick Mathewson
I was going to add a test for this, but I realized that it had no users. So, removed.

2015-05-07Write the outlines of a WritingTests.txt documentNick Mathewson
Also, add some sample tests to be examples.
2015-03-14Remove relative paths to header files.cypherpunks
The paths are already in the directory search path of the compiler therefore no need to include them in the source code.

2015-03-03Make the assert related to 15083 a tiny bit more tolerantNick Mathewson
2015-03-03Do not leave empty, invalid chunks in buffers during buf_pullupNick Mathewson
This fixes an assertion failure bug in 15083; bugfix on 0.2.0.10-alpha. Patch from 'cypherpunks'
2015-02-11Remove mempools and buf freelistsNick Mathewson
They have been off-by-default since 0.2.5 and nobody has complained. :) Also remove the buf_shrink() function, which hasn't done anything since we first stopped using contiguous memory to store buffers. Closes ticket 14848.

2014-12-30Allow IPv4 and IPv6 addresses in SOCKS5 FQDN requests.Yawning Angel
Supposedly there are a decent number of applications that "support" IPv6 and SOCKS5 using the FQDN address type. While said applications should be using the IPv6 address type, allow the connection if SafeSocks is not set. Bug not in any released version.

Because in 95 years, we or our successors will surely care about enforcing the BSD license terms on this code. Right?
