Nick Mathewson 0694263b75 Make round_to_next_multiple_of always round upwards.
Yes, even if it has to return a non-multiple.  This prevents us from
ever having a bug where we try to use it for allocation, and under-allocate.

Nick Mathewson 347fe449fe Move formatting functions around.
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!

Yawning Angel da6aa7bfa5 Allow a single trailing . when validating FQDNs from SOCKS.
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.

Yawning Angel 3f336966a2 Work around nytimes.com's broken hostnames in our SOCKS checks.
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.

David Goulet 8acccdbeac Add an util function to cast double to int64_t
Use it in the sample_laplace_distribution function to make sure we return
the correct converted value after math operations are done on the input
values.

Thanks to Yawning for proposing a solution.

Karsten Loesing dad5eb7e1f Tweak teor's and dgoulet's #13192 patches.
- Rewrite changes file.
 - Avoid float comparison with == and use <= instead.
 - Add teor's tor_llround(trunc(...)) back to silence clang warnings.
 - Replace tt_assert() with tt_i64_op() and friends.
 - Fix whitespace and a comment.

teor 09cac24373 Handle edge cases in the round_*_to_next_multiple_of functions
Consistently check for overflow in round_*_to_next_multiple_of.

Check all round_*_to_next_multiple_of functions with expected values.
Check all round_*_to_next_multiple_of functions with maximal values.

Related to HS stats in #13192.

teor 6d54bdbdcf Handle edge cases in laplace functions
Avoid division by zero.
Avoid taking the log of zero.
Silence clang type conversion warnings using round and trunc.
The existing values returned by the laplace functions do not change.

Add tests for laplace edge cases.
These changes pass the existing unit tests without modification.

Yawning Angel fa81508eb2 Use prctl() to have the kernel SIGTERM background processes on exit.
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.

Yawning Angel fda61e030e Implement "TOR_PT_EXIT_ON_STDIN_CLOSE".
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.

Arthur Edelstein cb714d896c Bug #8405: Report SOCKS username/password in CIRC status events
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"

Nick Mathewson 47760c7ba5 When decoding a base-{16,32,64} value, clear the target buffer first
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.

Fixes bug 13111.

Avoid overwriting .old key files with empty key files.
Skip loading zero-length extra info store, router store, stats, state,
and key files.
