Change thread_cancel to take a ** to an event, NULL-check
before dereferencing, and NULL the caller's pointer. Update
many callers to use the new signature.

The Solaris code has gone through a deprecation cycle. No-one
has said anything to us and worse of all we don't have any test
systems running Solaris to know if we are making changes that
are breaking on Solaris. Remove it from the system so
we can clean up a bit.

In case of config rollback is enabled,
record northbound transaction based on a control flag.
The actual frr daemons would set the flag to true via
nb_init from frr_init.
This will allow test daemon to bypass recording
transacation to db.

*: change the signature of the northbound callbacks to be more flexible
|
|
|
|
Having a fixed set of parameters for each northbound callback isn't a
good idea since it makes it difficult to add new parameters whenever
that becomes necessary, as several hundreds or thousands of existing
callbacks need to be updated accordingly.
To remediate this issue, this commit changes the signature of all
northbound callbacks to have a single parameter: a pointer to a
'nb_cb_x_args' structure (where x is different for each type
of callback). These structures encapsulate all real parameters
(both input and output) the callbacks need to have access to. And
adding a new parameter to a given callback is as simple as adding
a new field to the corresponding 'nb_cb_x_args' structure, without
needing to update any instance of that callback in any daemon.
This commit includes a .cocci semantic patch that can be used to
update old code to the new format automatically.

Replace sprintf with snprintf where straightforward to do so.
- sprintf's into local scope buffers of known size are replaced with the
equivalent snprintf call
- snprintf's into local scope buffers of known size that use the buffer
size expression now use sizeof(buffer)
- sprintf(buf + strlen(buf), ...) replaced with snprintf() into temp
buffer followed by strlcat

Replace all `random()` calls with a function called `frr_weak_random()`
and make it clear that it is only supposed to be used for weak random
applications.
Use the annotation described by the Coverity Scan documentation to

Same as before, instead of shoving this into a big central list we can
just put the parent node in cmd_node.

There is really no reason to not put this in the cmd_node.
And while we're add it, rename from pointless ".func" to ".config_write".

Our two northbound tools don't have embedded YANG modules like the
other FRR binaries. As such, ly_ctx_set_module_imp_clb() shouldn't be
called when the YANG subsystem it being initialized by a northbound
tool. To make that possible, add a new "embedded_modules" parameter
to the yang_init() function to control whether libyang should look
for embedded modules or not.
With this fix, "gen_northbound_callbacks" and "gen_yang_deviations"
won't emit "YANG model X not embedded, trying external file"
warnings anymore.

This is a full rewrite of the "back end" logging code. It now uses a
lock-free list to iterate over logging targets, and the targets
themselves are as lock-free as possible. (syslog() may have a hidden
internal mutex in the C library; the file/fd targets use a single
write() call which should ensure atomicity kernel-side.)
Note that some functionality is lost in this patch:
- Solaris printstack() backtraces are ditched (unlikely to come back)
- the `log-filter` machinery is gone (re-added in followup commit)
- `terminal monitor` is temporarily stubbed out. The old code had a
race condition with VTYs going away. It'll likely come back rewritten
and with vtysh support.
- The `zebra_ext_log` hook is gone. Instead, it's now much easier to
add a "proper" logging target.

*: fix ctype casts
|
|
The correct cast for these is (unsigned char), because "char" could be
signed and thus have some negative value. isalpha & co. expect an int
arg that is positive, i.e. 0-255. So we need to cast to (unsigned char)
when calling any of these.
