* Avoid assertion failure on unexepcted address family in DNS reply.Nick Mathewson2013-07-26
| | | | Fixes bug 9337; bugfix on 0.2.4.7-alpha.
* Rename log() to tor_log() for loggingNick Mathewson2013-02-01
| | | | | | | | | | | | | 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;

| * Add a TOR_SOCKET_T_FORMAT construction for logging sockets.Nick Mathewson2012-11-02
| | | | | | | | | | | | We need this since win64 has a 64-bit SOCKET type. Based on a patch from yayooo for 7260, forward-ported to 0.2.4.
* | Remove some XXXX commens in dns.cNick Mathewson2012-11-15
| | | | | | | | | | | | | | | | | | Previously, I was freaking out about passing an unspec address to dns_found_answer() on an error, since I was using the address type to determine whether the error was an error on an ipv4 address lookup or on an ipv6 address lookup. But now dns_found_answer() has a separate orig_query_type argument to tell what kind of query it is, so there's no need to freak out.
* | Make DNS resolve requests work for IPv6Nick Mathewson2012-11-14
| | | | | | | | | | | | | | * If there's an IPv4 and an IPv6 address, return both in the resolved cell. * Treat all resolve requests as permitting IPv6, since by the spec they're allowed to, and by the code that won't break anything.
* | Fix a bug in policy_is_reject_star() that was making IPv4 exits breakNick Mathewson2012-11-14
| | | | | | | | | | | | | | | | IPv4-only exits have an implicit "reject [::]/0", which was making policy_is_reject_star() return 1 for them, making us refuse to do hostname lookups. This fix chanes policy_is_reject_star() to ask about which family we meant.

* | Repair DNS NEXIST hijacking workaroundNick Mathewson2012-11-14
| | | | | | | | | | | | | | | | | | | | | | | | The code previously detected wildcarding and replaced wildcarded answers with DNS_STATUS_FAILED_PERMANENT. But that status variable was no longer used! Remove the status variable, and instead change the value of 'result' in evdns_callback. Thank goodness for compiler warnings. In this case, unused-but-set-variable. Thanks to Linus for finding this one.
* | Define a wrapper for evdns_base_resolve_ipv6 for systems w/o libevent 2Nick Mathewson2012-11-14

* | Make address_is_invalid_destination recognize ipv6 addrs as valid.Nick Mathewson2012-11-14

* | Revise the DNS subsystem to handle IPv6 exits.Nick Mathewson2012-11-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now, every cached_resolve_t can remember an IPv4 result *and* an IPv6 result. As a light protection against timing-based distinguishers for IPv6 users (and against complexity!), every forward request generates an IPv4 *and* an IPv6 request, assuming that we're an IPv6 exit. Once we have answers or errors for both, we act accordingly. This patch additionally makes some useful refactorings in the dns.c code, though there is quite a bit more of useful refactoring that could be done. Additionally, have a new interface for the argument passed to the evdns_callback function. Previously, it was just the original address we were resolving. But it turns out that, on error, evdns doesn't tell you the type of the query, so on a failure we didn't know whether IPv4 or IPv6 queries were failing. The new convention is to have the first byte of that argument include the query type. I've refactored the code a bit to make that simpler.

* | Make DNS callback pass IPv6 answers to dns_answer_foundNick Mathewson2012-11-14
| | | | | | | | | | | | | | | | Also, count ipv6 timeouts vs others. If we have too many ipv6 requests time out, then we could be degrading performance because of a broken DNS server that ignores AAAA requests. Other cases in which we never learn an AAAA address aren't so bad, since they don't slow A (ipv4) answers down very much.
* | Make dns wildcarding checks work for ipv6Nick Mathewson2012-11-14

* | Simplest version of server-side IPv6 support (no dns)Nick Mathewson2012-11-14
|/ | | | | | | This is a relatively simple set of changes: we mostly need to remove a few "but not for IPv6" changes. We also needed to tweak the handling of DNS code to generate RESOLVED cells that could get an IPv6 answer in return.
* Rename all reserved C identifiers we definedNick Mathewson2012-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* When iterating over connections pending DNS, skip marked onesNick Mathewson2012-08-17
| | | | | | | | Failure to do this would lead to double-free cases and similar, especially when the exit's DNS was broken. See bug 6472 for full details; this is a fix for 6472. Anonymous patch from "cypherpunks" on trac.

|
* Fix a hard-to-trigger memory leak in launch_resolveNick Mathewson2012-05-18
| | | | | | | | | | | To hit this leak, you need to be a relay that gets a RESOLVE request or an exit node getting a BEGIN or RESOLVE request. You must either have unconfigured (and unconfigurable) nameservers, or you must have somehow set DisableNetwork after a network request arrived but before you managed to process it. So, I doubt this is reached often. Still, a leak's a leak. Fix for bug 5916; bugfix on 0.2.3.9-alpha and 0.1.2.1-alpha.
* Use the standard _WIN32, not the Torism MS_WINDOWS or deprecated WIN32Nick Mathewson2012-01-31
| | | | | | | | | | | This commit is completely mechanical; I used this perl script to make it: #!/usr/bin/perl -w -i.bak -p if (/^\s*\#/) { s/MS_WINDOWS/_WIN32/g; s/\bWIN32\b/_WIN32/g; }
* Use !SOCKET_OK to test if a socket is uninitializedSebastian Hahn2012-01-23
| | | | | This fixes a compile warning on Windows. Fixes bug 4946, not in any released version.
* Rename nonconformant identifiers.Nick Mathewson2012-01-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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;
* Use SOCKET_OK macros in even more placesNick Mathewson2012-01-17
| | | | | | Add a TOR_INVALID_SOCKET macro to wrap -1/INVALID_SOCKET. Partial work for bug4533.
* Make sure we never launch an evdns resolve when DisableNetwork is 1Nick Mathewson2011-11-29
|
* Change "reverse_lookup_name" functions to refer to "PTR_name"sNick Mathewson2011-10-11
| | | | | | | | | | Under the new convention, having a tor_addr.*lookup function that doesn't do hostname resolution is too close for comfort. I used this script here, and have made no other changes. s/tor_addr_parse_reverse_lookup_name/tor_addr_parse_PTR_name/g; s/tor_addr_to_reverse_lookup_name/tor_addr_to_PTR_name/g;
* Fix names of functions that convert strings to addrsNick Mathewson2011-10-11
| | | | | | | | | | | | | | | | | | | | Now let's have "lookup" indicate that there can be a hostname resolution, and "parse" indicate that there wasn't. Previously, we had one "lookup" function that did resolution; four "parse" functions, half of which did resolution; and a "from_str()" function that didn't do resolution. That's confusing and error-prone! The code changes in this commit are exactly the result of this perl script, run under "perl -p -i.bak" : s/tor_addr_port_parse/tor_addr_port_lookup/g; s/parse_addr_port(?=[^_])/addr_port_lookup/g; s/tor_addr_from_str/tor_addr_parse/g; This patch leaves aton and pton alone: their naming convention and behavior is is determined by the sockets API. More renaming may be needed.
* Make the get_options() return constNick Mathewson2011-06-14
| | | | | | | | This lets us make a lot of other stuff const, allows the compiler to generate (slightly) better code, and will make me get slightly fewer patches from folks who stick mutable stuff into or_options_t. const: because not every input is an output!

| * Fix check for failed evdns request creationNick Mathewson2011-01-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using libevent 2, we use evdns_base_resolve_*(). When not, we fake evdns_base_resolve_*() using evdns_resolve_*(). Our old check was looking for negative values (like libevent 2 returns), but our eventdns.c code returns 1. This code makes the check just test for nonzero. Note that this broken check was not for _resolve_ failures or even for failures to _launch_ a resolve: it was for failures to _create_ or _encode_ a resolve request. Bug introduced in 81eee0ecfff3dac1e9438719d2f7dc0ba7e84a71; found by lodger; uploaded to trac by rransom. Bug 2363. Fix on 0.2.2.6-alpha.
