Nick Mathewson 5fa2b32200 Coverity: fix test issues with always-present 'service' var.
Coverity is worried that we check "service" at the end of these test
functions, since it doesn't see any way to reach the cleanup code
without having first dereferenced the variable.

Removing the check would be unwise in this case: instead we add a
tt_assert check before using "service" so that coverity thinks that
the check is doing something useful.

Bugfix on 0.3.2.1-alpha.

Nick Mathewson 68792f77e5 Fix a few coverity unitinitialzed-value warnings in the unit tests.
Coverity can't see that it is not in fact going to read
uninitialized memory here, so we initialize these values
unconditionally.

Bugfix on 0.4.0.1-alpha.

Nick Mathewson f55598f870 Coverity: different implementation for csiphash
Coverity has had trouble figuring out our csiphash implementation,
and has given spurious warnings about its behavior.

This patch changes the csiphash implementation when coverity is in
use, so that coverity can figure out that we are not about to read
beyond the provided input.

Closes ticket 31025.

Nick Mathewson 0fa3dc3228 begin_cell_parse(): Add an assertion to please coverity.
Coverity doesn't understand that if begin_cell_parse() returns 0 and
sets is_begindir to 0, its address field will always be set.

Fixes bug 30126; bugfix on 0.2.4.7-alpha; Fixes CID 1447296.

teor adb8538e7b address/resolve: Require square brackets on IPv6 address:ports
When parsing addreses via Tor's internal address:port parsing and
DNS lookup APIs, require IPv6 addresses with ports to have square
brackets.

But allow IPv6 addresses without ports, whether or not they have
square brackets.

Fixes bug 30721; bugfix on 0.2.1.5-alpha.

teor cd1de99468 resolve: consistently parse IP addresses in square brackets
When parsing addreses via Tor's internal DNS lookup API:
* reject IPv4 addresses in square brackets (with or without a port),
* accept IPv6 addresses in square brackets (with or without a port), and
* accept IPv6 addresses without square brackets, as long as they have no port.

This change completes the work started in 23082, making address parsing
consistent between tor's internal DNS lookup and address parsing APIs.

Fixes bug 30721; bugfix on 0.2.1.5-alpha.

Nick Mathewson a7835202cf Turn several properties of types or variables into flags.
"unsettable" is a property of types.  LINELIST_V and OBSOLETE are
unsettable, meaning that they cannot be set by name.

"contained" is a property of types.  I'm hoping to find a better
name here.  LINELIST_S is "contained" because it always appears
within a LINELIST_V, and as such doesn't need to be dumped ore
copied independently.

"cumulative" is a property of types. Cumulative types can appear
more than once in a torrc without causing a warning, because they
add to each other rather than replacing each other.

"obsolete" is a property of variables.

"marking fragile" is now a command that struct members can accept.

With these changes, confparse and config no longer ever need to
mention CONFIG_TYPE_XYZ values by name.

Nick Mathewson c60a85d22a Add a "typed_var" abstraction to implement lvalue access in C.
Right now, this has been done at a high level by confparse.c, but it
makes more sense to lower it.

This API is radically un-typesafe as it stands; we'll be wrapping it
in a safer API as we do #30914 and lower the struct manipulation
code as well.
