The test requires new git binary.
It's not necessary installed everywhere.
Skip the test if git binary does not support bisection.
Also reoder functions from more important to less important.
Mark the test as parallel.
Move individual tests into subtests.
Split trace per subtest.
It also hash high branching factor and a bug is more likely in the callback.
For the added test we used to say:
INFO: rcu detected stall in __sys_sendmsg
now we say more useful:
INFO: rcu detected stall in tc_modify_qdisc
fix: hugetlb.<hugepagesize>.limit_in_bytes can be set.
hugetlb.<hugepagesize>.usage_in_bytes is for reading.
added descriptions for the following resource controllers:
net_cls, net_prio, devices, freezer.
Since we started using modules, it's a good time to update some deps.
Update to latest official versions packages that have newer versions.
Update #1247
Godep is long deprecated and modules is the future.
Updating dependencies with godep is painful and non-transparent.
This will hopefully help to create custom golangci-lint linters.
The change was created with:
go mod init
rm -rf vendor
go mod vendor
Fixes#1247
"git clean -fd" does not remove ignored files,
while can mess state when .gitignore changes across commits.
Use "git clean -fdx" to delete ignored files as well.
Config minimization did not update test results for the starting commit.
Test result for the starting commit still refered to the original config,
not the minimized config that was actually used during bisection.
Change a test to actually produce a new config as it is supposed
to do during config minimization and check the resulting config.
Add a regression test for the bug where we committed a broken config.
One of main outputs of the config minimization is the new config,
but tests don't do any single check of it.
Check the resulting config (is it correct in all cases?).
Ignoring errors is bad. It leads to silent failures.
If there is some particular error condition that is expected
to happen and we want to ignore, we need to ignore that one only
rather than all potenital errors in the whole process.
Implement Linux kernel configuration bisection. Use bisected minimalistic
configuration in commit bisection. Utilizes config_bisect.pl script from Linux
kernel tree in bisection.
Modify syz-bisect to read in kernel.baseline_config. This is used as a "good"
configuration when bisection is run.
Add new new Syzkaller configuration option kernel_baseline_config. This option
is supposed to be used by kernel configruation bisection as a "good" config"

Somehow informational:true is not enough to not produce errors.
We are constantly getting nacks on PRs like:
x codecov/patch — 59.2% of diff hit (target 65.3%)
Add back and relax target and treshold.
Suggest to checkout linux kernel from kernel.org rather than from github.
github is a mirror and we don't use it ourselves and I think it's
generally not used by kernel developers. The kernel.org repo is
the canonical location.
Use unix.Unmount instead of manually wrapping SYS_UMOUNT2.
Use unix.IoctlSetPointerInt instead of manually wrapping SYS_IOCTL. This
also allows to use FS_IOC_SETFLAGS instead of manually defining it for
each GOARCH.
