2ba71ec506 pkg/repro: don't enable features missing on the target 
Manager has already checked what features are present on the target.
But if we detected that, say, USB is missing, we still enabled it
in the starting csource options. This is wrong, increases configuration
minimization time and may lead to some obscure bugs.

a86ce602b3 syz-runtest: disable csource tests for HostFuzzer targets 
HostFuzzer targets require that we cross-compile the csource tests and
then copy them to the target system. The code to copy files is
currently missing from syz-runtest; also, at least for Fuchsia (which
uses HostFuzzer mode), cross-compiling is non-trivial.

f3ba1b5b7b sys/syz-sysgen: add -src and -out flags 
This is useful for integrating into Fuchsia's build system, where we
need to be able to run syz-sysgen with a read-only source directory,
and emit the output files elsewhere.

06417ff868 pkg/report: add tests for rcu stalls in kmem_cache_alloc 
I though maybe we need special handling for them:
stop at kmem_cache_alloc function. But now I am not sure.
This can also be an infinite loop which calls kmalloc/kfree.
Let's not change code for now, just fix things with tests
(this is a good representative set).

52fd7b7d77 tools: add syz-big-env 
On top of syz-env it provides akaros/fuchsia/netbsd toolchains and gcloud sdk.
With this it's possible to run dashboard/app tests on CI and locally
and test executor build and pkg/{csource,cover} for these OSes.

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.

which is mostly equivalent to mailing to nobody.

d19ed305ae pkg/build/fuchsia: Enable KASAN by default. 
This commit makes syzkaller build the kasan variant of fuchsia by
default.

Support for kernel address sanitizer has landed in fuchsia since commit
`54c5edfc37afe7294256552cefefca64c6ce7e94`[0].

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).
