Nick Mathewson 39d09ea081 doxygen: add @file declarations for src/lib
If a file doesn't use the file command (either \file or @file),
Doxygen won't try to process it.

These declarations also turned up a doxygen warning for
crypto_ope.c; I fixed that too.

Nick Mathewson 407fb0c35c Move config_format_t and allied definitions into conftypes.h
Since these are needed by every module that is _configurable_, they
belong in lib/conf, not lib/confmgt.

Nick Mathewson aa6b4b62db confparse: Add a function to check the magic of a toplevel object. 2019-10-25 08:08:43 -04:00
Nick Mathewson e0ae137df5 Write a new set of config validation callbacks.
Unlike legacy_validate_fn_t, these callbacks have separation of
duties, into:

    * early normalization and computation.
    * validation
    * transition checking
    * late normalization and computation

Only the first and last steps get mutable objects.  Only the
transition-checking step gets to see the previous values of this
object.

Nick Mathewson dc6d7f072d Make foo_validate() functions call config_validate().
The former foo_validate() functions are now toplevel
legacy_validate_fn callbacks.  The new foo_validate() functions now
call them.

This change lets us remove the old shared_random disk state
validation callback entirely.

Nick Mathewson 0cb4238537 Add a config_validate() function to invoke verify callbacks.
As we turn our monolithic configuration objects into suites of
smaller module-specific configuration objects, we will want each one
to be able to provide its own verification callbacks.  That means
that instead of invoking these verification callbacks directly, we will
want to call them via the configuration manager object.
2019-10-24 20:30:32 -04:00
Nick Mathewson 4a248bafba Rename validate_fn{,_t} to start with "legacy_".
The current API of this callback mixes responsibilities, including:
  * validation
  * transition checking
  * processing (modifying) the configuration object.

These will have to be disentangled piece by piece, so for now, we'll
have "legacy" validate functions as well.

Nick Mathewson 6bc2b41e54 config validation: make the "old_options" argument const.
We can't do this with the "options" argument yet, since several
places in the code change those right now.

Nick Mathewson 697d99e504 validate_fn(): remove now-unused defaults and from_setconf.
These arguments were only used by options_validate, and are now
ignored even there.

Alexander Færøy 7a64f6ea04 Ensure that the exit callback is called if CreateProcessA() fails on Windows.
This patch fixes an issue where the exit handler is not called for the
given process_t in case CreateProcessA() fails. This could, for example,
happen if the user tries to execute a binary that does not exist.

Alexander Færøy 85b4a5c276 Handle errors from execve() in the Unix process backend more gracefully.
This patch removes a call to tor_assert_unreached() after execve()
failed. This assertion leads to the child process emitting a stack trace
on its standard output, which makes the error harder for the user to
demystify, since they think it is an internal error in Tor instead of
"just" being a "no such file or directory" error.

The process will now instead output "Error from child process: X" where
X is the stringified version of the errno value.

Nick Mathewson 3a73f6612a Replace add_temp_log() with add_default_log().
We used to have this function so that we could mark our initial
log-to-stdout as specifically temporary so that we would delete it
once regular logs were configured.  But it's no longer necessary to
mark these logs as temporary, since we now use a mark-and-sweep
process to ensure that _all_ not-configured logs are closed when we
change our configuration.

Instead, this function will be the basis of a refactoring in how we
handle default logs.

Tobias Stoeckmann d91ad5112e Check tor_vasprintf for error return values.
In case of error, a negative value will be returned or NULL written into
first supplied argument.

This patch uses both cases to comply with style in the specific files.

A tor_vasprintf error in process_vprintf would lead to a NULL dereference
later on in buf_add, because the return value -1 casted to size_t would
pass an assertion check inside of buf_add.

On the other hand, common systems will fail on such an operation, so it
is not a huge difference to a simple assertion. Yet it is better to
properly fail instead of relying on such behaviour on all systems.
