net: sched: propagate extack to cls offloads on destroy and only with skip_sw
This series some of Jiri's comments and the fact that today drivers
may produce extack even if there is no skip_sw flag (meaning the
driver failure is not really a problem), and warning messages will
only confuse the users.
First patch propagates extack to destroy as requested by Jiri, extack
is then propagated to the driver callback for each classifier. I chose
not to provide the extack on error paths. As a rule of thumb it seems
best to keep the extack of the condition which caused the error. E.g.
err = this_will_fail(arg, extack);
if (err) {
undo_things(arg, NULL /* don't pass extack */);
return err;
}
Note that NL_SET_ERR_MSG() will ignore the message if extack is NULL.
I was pondering whether we should make NL_SET_ERR_MSG() refuse to
overwrite the msg, but there seem to be cases in the tree where extack
is set like this:
err = this_will_fail(arg, extack);
if (err) {
undo_things(arg, NULL /* don't pass extack */);
NL_SET_ERR_MSG(extack, "extack is set after undo call :/");
return err;
}
I think not passing extack to undo calls is reasonable.
v2:
- rename the temporary tc_cls_common_offload_init().

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
