There have been quite a few of improvements, but the main thing recently is that I've been turning off warnings by default so that the zero day bot can send emails without my filtering them. I haven't been sending Spectre v1 warnings for some time. These are places where we should add array_index_nospec(). It still an issue but I've never felt like I've understood the issue well enough to triage these. If anyone would like to help triage these warnigns I could probably improve the warning a lot. (Does anyone have contacts at Intel or AMD?) The other warning that I disabled was about uninitialized variables. This check is pretty good, but it requires cross function analysis and the zero day bot doesn't do that. For example, we often have loops: for (i = 0; i < parameter_limit; i++) { Without cross function analysis we have to consider that parameter_limit could be zero or even negative. The other things about uninitialized variables is that Clang does a pretty good job warning about these. The zero day bot has a false positive with regards to "iterator not incremented" warnings, but I've never been able to reproduce that despite trying really hard so I disabled that as well. I think most people use Smatch from git but if you're using a package then there are lots of improvements in here. $ git log --oneline 1.73..1.74 | wc -l 874 All good things. :) regards, dan carpenter
