We currently build binaries for all targets into bin.
This makes mess in bin/ and does not allow testing of different archs.
Build target binaries into bin/OS_ARCH/ subdirs.
Host binaries are still built into bin/.
Update #333
Update #324
Update #191
Add new "syzkaller_descriptions" config param that allows
to specify a dir with additional syscall descriptions
that will be copied on top of syzkaller checkout.
Dashboard needs to know when bug fixing commits reach
builders in order to fully close bugs.
Send commits that dashboard is interested in to dashboard.
If manager exits during start, it's hard to understand what happens.
Save the previous manager log as manager.log.old until we have a better solution.
Also log errors on 0 log level.
Don't write hub/dashboard params if they are not enabled
in syz-ci config. Otherwise manager gets name but not addr/key,
and that does not pass config validation.
Currently we have unix permissions for new files/dirs
hardcoded throughout the code base. Some places use 0644,
some - 0640, some - 0600 and a variety of other constants.
Introduce osutil.MkdirAll/WriteFile that use the default
permissions and use them throughout the code base.
This makes permissions consistent and also allows to easily
change the permissions later if we change our minds.
Also merge pkg/fileutil into pkg/osutil as they become
dependent on each other. The line between them was poorly
defined anyway as both operate on files.
We currently store 3 tags (compiler id, kernel commit and config hash).
But we also kernel git report/branch. To not store 2 more tag files,
combine everything into a single json file that holds all info about the build.
Will allow simpler extenstion in future as well.
