2015-07-31Move formatting functions around.Nick Mathewson
The base64 and base32 functions used to be in crypto.c; crypto_format.h had no header; some general-purpose functions were in crypto_curve25519.c. This patch makes a {crypto,util}_format.[ch], and puts more functions there. Small modules are beautiful!
2015-07-27Allow a single trailing `.` when validating FQDNs from SOCKS.Yawning Angel
URI syntax (and DNS syntax) allows for a single trailing `.` to explicitly distinguish between a relative and absolute (fully-qualified) domain name. While this is redundant in that RFC 1928 DOMAINNAME addresses are *always* fully-qualified, certain clients blindly pass the trailing `.` along in the request. Fixes bug 16674; bugfix on 0.2.6.2-alpha.

2015-07-15Add more EINVAL errno setting on key read failuresNick Mathewson
Teor found these. This is for part of #16582.
2015-07-14Make file-reading and key-reading preserve errnoNick Mathewson
This is an important part of #16582.
2015-06-24Work around nytimes.com's broken hostnames in our SOCKS checks.Yawning Angel
RFC 952 is approximately 30 years old, and people are failing to comply, by serving A records with '_' as part of the hostname. Since relaxing the check is a QOL improvement for our userbase, relax the check to allow such abominations as destinations, especially since there are likely to be other similarly misconfigured domains out there.

2015-03-26Use prctl() to have the kernel SIGTERM background processes on exit.Yawning Angel
This uses a Linux-ism to attempt to always clean up background processes if possible. Note that it is not a catch-all, in that executables with suid/sgid or elevated capabilities will have the prctl() attribute stripped as part of the execve(). Resolves ticket 15471.
2015-03-26Implement "TOR_PT_EXIT_ON_STDIN_CLOSE".Yawning Angel
Background processes spawned by Tor now will have a valid stdin. Pluggable transports can detect this behavior with the aformentioned enviornment variable, and exit if stdin ever gets closed.

2015-01-28Bug #8405: Report SOCKS username/password in CIRC status eventsArthur Edelstein
Introduces two new circuit status name-value parameters: SOCKS_USERNAME and SOCKS_PASSWORD. Values are enclosing in quotes and unusual characters are escaped. Example: 650 CIRC 5 EXTENDED [...] SOCKS_USERNAME="my_username" SOCKS_PASSWORD="my_password"
2015-01-15Restrict sample values of the Laplace distribution to int64_t.George Kadianakis
This helps avoid undefined behavior from casting big double values to int64_t. Fixes #14090.

Have clients and authorities both have new behavior, since the fix for bug 11243 has gone in. But make clients still accept accept old bogus HSDir descriptors, to avoid fingerprinting trickery. Fixes bug 9286.

2014-12-22When decoding a base-{16,32,64} value, clear the target buffer firstNick Mathewson
This is a good idea in case the caller stupidly doesn't check the return value from baseX_decode(), and as a workaround for the current inconsistent API of base16_decode. Prevents any fallout from bug 14013.

2014-11-08Stop failing when key files are zero-lengthteor
Instead, generate new keys, and overwrite the empty key files. Adds FN_EMPTY to file_status_t and file_status. Fixes bug 13111. Related changes due to review of FN_FILE usage: Stop generating a fresh .old RSA key file when the .old file is missing. Avoid overwriting .old key files with empty key files. Skip loading zero-length extra info store, router store, stats, state, and key files.
2014-11-08Stop crashing when a NULL filename is passed to file_status()teor
Stop crashing when a NULL filename is passed to file_status(), instead, return FN_ERROR. Also return FN_ERROR when a zero-length filename is passed to file_status(). Fixed as part of bug 13111.

Check all date/time values passed to tor_timegm and parse_rfc1123_time for validity, taking leap years into account. Improves HTTP header validation. Avoid unlikely signed integer overflow in tor_timegm on systems with 32-bit time_t. Fixes bug 13476.
