6f3e1c7c67 pkg/build: chmod key file before running qemu

f7fbb18cba syz-manager: add detailed coverage logging 
Originally, syz-manager confusingly logs corpusSignal as "cover".
Change syz-manager's logging to output corpusSignal, corpusCover
and maxSignal.
Add a field in Stats to store maxSignal.

2510d1afaa pkg/report: avoid producing no guilty file 
If we produce no guilty file at all, the report is mailed only to LKML,
which is mostly equivalent to mailing to nobody.
If we skip all files, return the first one.

cdc5f8a23e sys/targets: support SOURCEDIR_GOOS vars 
Support SOURCEDIR_GOOS env vars as an alternative to SOURCEDIR.
SOURCEDIR_GOOS takes precedence.
This allows to test several OSes at the same time.

default.

syzkaller testing may be slowed down by concurrent kernel builds too much

142a0957d0 sys/openbsd: change type of sysctl namelen argument 
The namelen argument must reflect the number of elements in the name
vector. Since it's a vector of integers, bytesize4 seems more
appropriate.

With help from by Dmitry[1].

fdf90f622b pkg/cover: add test for report generation 
Test various combinations of no debug info,
no coverage instrumentation, no PCs, bad PCs, good PCs,
and what errors we produce for these.
Also implement support for cross-arch reports:
prefix objdump with cross-compile prefix
(e.g. aarch64-linux-gnu-objdump instead of objdump).

vm/isolated: fix hang when target_reboot is not set 
* updated the contributor list

* Fixes #1750, syz-manager hangs with "target_reboot:" false in isolated VM mode

If in the isolated VM mode, "target_reboot": false option is set in the
syz-manager's configuration, it hangs forever. syz-manager essentially
keeps on waiting for the VM to reboot, while a reboot is never triggered
due to target_reboot option being set to false. The fix is to perform the
waitRebootAndSSH() check only when target_reboot is set to true.

File(s) changed:

    vm/isolated/isolated.go: Move the waitRebootAndSSH() check inside the correct block
