Running sys/*/test programs requires real machines and kernels for each OS.
We can't do that in unit tests, but at least try to deserialize these programs
so that they don't get rotten.
Ensure that we have at least 1GB per Makefile job.
Go compiler/linker can consume significant amount of memory
(observed to consume at least 600MB). See #1276 for context.
Update #1276
One instance we observed that objdump hanged due to stdout
pipe overflow due to panic in archCallInsn.
The reason for the original panic is still unclear,
but fix the objdump hang. We need to terminate objdump
and propagate the panic.
Also extend the panic messages.
* sys/fuchsia: update zx_clock_get.
zx_clock_get was deprecated and replaced by zx_clock_get_new. In a
recent CL[0], they replaced the zx_clock_get by zx_clock_get_new and
moved all client. This commit updates syzkaller to use the new function.

* run make extract && make generate
Instead of defining the __GLIBC_USE macro on every OS, we are just
defining it based on a parameter. That parameter is set to false for all
OSs except for fuchsia.
When I try to run `make extract` for fuchsia, the clang compiler
complains that __GLIBC_USE is undefined.
This CL just defines it to be an always false function-like macro if it
was not defined.
This commit removes the fuchsia-power fidl definitions. The interface
doesn't have a service implementing it in fuchsia, and it is causing
issues in make extract.
1. Change HID descriptions to allow devices to have two interrupt endpoints.
2. Remove unneeded responses to OUT control requests from descriptions.
3. Add some debugging code to detect and report missing descriptions.
Update descriptions to be compatible with latest linux-next
(next-20190715), which in theory will match v5.3-rc1 when the merge
window closes.
- KEYCTL_GRANT_PERMISSION was reverted. So remove its description.
- CRYPTO_ALG_TYPE_DIGEST was removed. So remove its description.
- IB_QP_CREATE_SIGNATURE_EN was renamed to IB_QP_CREATE_INTEGRITY_EN.
Also remove the sys/linux/rdma_*.const files which were incorrectly
checked into git. The real copies of those files are in
sys/linux/dev_infiniband_rdma_*.const.
For now I did *not* check for other new APIs that need to be described.
Currently the 'image_device' config option in qemu.go doesn't properly
support the modern '-drive' argument for describing qemu hard disks.
In fact the various old ways to define qemu drives all boil down to
the common form '-drive if=TYPE,bus=BUS,unit=UNIT,OPTS...'
For example '-hda img' is equivalent to '-drive index=0,media=disk,file=img'.
Let's make the 'image_device' config option support both forms.

- Add KEYCTL_MOVE (new in v5.3)
- Add KEYCTL_CAPABILITIES (new in v5.3)
- Add KEYCTL_GRANT_PERMISSION (new in v5.3)
- Remove KEY_PERM_UNDEF (was only ever in an internal kernel header,
not in UAPI; removed in v5.3)
On OpenBSD, the executor sometimes manages to set the memory resource
limit 0 causing any following memory allocation to fail. Since threads
are potentially created from such a thread which cannot allocate any
memory, the executor will exit non-zero which in turn will cause
false-positive panics to be reported. For more info see the
discussion[1] in PR #1243.
Instead, if hitting a fatal error during thread creation exit zero.

In the various linux build instructions, add pointers to the main
doc with instructions for building syzkaller.
These instructions were present before commit d23e90a7b4 ("all:
switch to Go 1.12"). They were duplicated across files. Since the
commit the instructions are in one place. Make it easier to find
them from the platform-specific setup guides.
Also clarify in the x86_64 guide that using a precompiled compiler
from the supplied list is optional if the distribution provided
compiler is recent enough. Before commit d28f4ce ("Update
setup_ubuntu-host_qemu-vm_x86-64-kernel.md") the file had explicit
build instructions. Those are no longer needed.
Fix several nasty bugs in minimization that could lead
to almost arbitrary results. These bugs affected both
crash minimization and corpus population.
Extend the randomized test to catch these bugs.
Add additional asserts to code to catch similar bugs in future.
