Below is the list of build error/warning regressions/improvements in
v4.18-rc7[1] compared to v4.17[2].
Summarized:
- build errors: +1/-1
- build warnings: +216/-46406
JFYI, when comparing v4.18-rc7[1] to v4.18-rc6[3], the summaries are:
- build errors: +0/-1
- build warnings: +72/-62
Note that there may be false regressions, as some logs are incomplete.
Still, they're build errors/warnings.
Happy fixing! ;-)
Thanks to the linux-next team for providing the build service.

There are quite some -Wstringop-* warnings, so here is some
information that may be useful and/or save time for other maintainers:
* Many of these (-Wstringop-*) happen only on recent GCCs, e.g. 8.1.
* Most of the targets in the build bot (i.e. the linked URLs) do not
use such modern GCC -- you need to take a look at e.g.
linus/parisc-allmodconfig/parisc.
* If your strings are intended to be non-null-terminated, we could
mark them with the new nonstring attribute (we were discussing adding
support for it a few months ago, the patch is in the list if you want
to test if it helps in your case: see [1]).
* For drivers/auxdisplay/, it seems that GCC 8.1/8.2 (the release
versions) do not trigger some of the warnings (nor the current 9.0). I
compiled a quite old GCC 8.0 (while it was in development,
905e9975935e1c) after -Wstringop-* was introduced and the warnings are
triggered when compiling the untouched kernel sources. However, if I
pick a reduced test case and when building *outside of the kernel*,
the warnings appear again in 8.1/8.2/current 9.0, see [2] below. I
guess that is a result of the warnings requiring some optimization
passes enabled. Martin Sebor (CC'd) fixed some false positives from
what I can see in gcc's log, but possibly there are still some quirks
(?). I am unsure what options the linus/parisc-allmodconfig/parisc
target using, since even the text of the warning itself is different.
Also, a suggestion for Geert (or whoever is maintaining the bot): it
would be nice to see from which target the warnings are exactly coming
from. Many/most warnings come from many/most targets, but at least
knowing 1 of them would be nice.
Hope that helps,
Miguel

Thanks for pointing this out!
The first two calls are diagnosed because GCC uses the size
of the destination array as the size of the accessed object
(it would be invalid to write past its end and into the next
subobject). In the last call, since the destination array
is the last member of the enclosing object, GCC conservatively
treats it as a (potential) flexible array member and decides
the actual array could be bigger than its type implies. This
heuristic is designed to throttle optimization and doesn't
necessarily have to impact diagnostics (they could be more
strict) but the code for both for this warning is the same
so we end up with a false negative. The -Wstringop-overflow
warning uses its own more refined logic and would trigger on
this case so it makes sense tighten up the truncation warning
and diagnose both. I opened bug 86764 in GCC Bugzilla to
take care of this.
The just released GCC 8.2 fixes a few -Wstringop-truncation
false positives based on some of the feedback I got. If
there are any other issues (false positives or negatives)
please let me know.

I used to upload the summaries containing that information to kernel.org,
but stopped doing so when kup was introduced (and I had to spend time to
learn how to use kup).
I've attached the summary for v4.18-rc7.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.

I see, I suspected something was going on. It is very good to know the
reason behind it. When the feature is more stable, maybe it is a good
idea to add some of the known false positives/negatives to the GCC
docs (those that cannot be fixed), if any.

Thanks a lot -- following it.

I will! Sometimes I am not sure if reporting such things related to
new-ish features like this since they might be trivial, intended, or
impossible-to-fix; given how new and/or optimization-dependent they
are; and therefore wasting people's time :)
