Add new command line option for exporting coverage information
calculated form rawcover file input into CSV file. The columns of
the exported file are:
Filename - function source file path
Function - function name
Percent - coverage percentage
PCs - number of total program counters

Add fstab entry to mount the root filesystem read-write after boot. This
has been done with commit 873745 for create-image.sh. Maybe this hint is
not necessary for GCE but it is required when running on other platforms
(e.g. VMware).
Two virtual wireless devices are instantiated during network devices
initialization.
A new flag (-wifi) is added that controls whether these virtual wifi
devices are instantiated and configured during proc initialization.
Also, two new pseudo syscalls are added:
1. syz_80211_inject_frame(mac_addr, packet, packet_len) -- injects an
arbitrary packet into the wireless stack. It is injected as if it
originated from the device identitied by mac_addr.
2. syz_80211_join_ibss(interface_name, ssid, ssid_len, mode) --
puts a specific network interface into IBSS state and joins an IBSS
network.
Arguments of syz_80211_join_ibss:
1) interface_name -- null-terminated string that identifies
a wireless interface
2) ssid, ssid_len -- SSID of an IBSS network to join to
3) mode -- mode of syz_80211_join_ibss operation (see below)
Modes of operation:
JOIN_IBSS_NO_SCAN (0x0) -- channel scan is not performed and
syz_80211_join_ibss waits until the interface reaches IF_OPER_UP.
JOIN_IBSS_BG_SCAN (0x1) -- channel scan is performed (takes ~ 9
seconds), syz_80211_join_ibss does not await IF_OPER_UP.
JOIN_IBSS_BG_NO_SCAN (0x2) -- channel scan is not performed,
syz_80211_join_ibss does not await IF_OPER_UP.
Local testing ensured that these syscalls are indeed able to set up an
operating network and inject packets into mac80211.
And populate images with some files,
which should make both mounting and resulting dir more interesting.
Note: this adds 100MB of image files into the repo...
Maybe we need to think of some other way of string these images...
tools/create_{f2fs,btrfs}_image.sh are... well, shell scripts.
It's hard to scale this appraoch to more file systems
avoiding duplication and stupid errors while doing proper
error handling and parallelization.
Upgrade syz-imagegen to generate full test files and replace
the shell scripts.
f2fs -O=compression options is removed, it does not seem to be
supported by mkfs.f2fs, it always says:
Error: Wrong features
The shell script used it, but it seems that the way it passed
arguments (in a single '-quoted string) just made mkfs misparse
the arguments (use only the first one?) and so -O=compression
and most other arguments were simply ignored.
create-image.sh assumes that the qemu name and the Debian name for the
target architecture are the same. This is not always true.
For comedy and/or historical reasons, Debian refers to 64-bit little
endian PowerPC as ppc64el, whereas qemu and most other things use ppc64le.
Debian refers to aarch64 as arm64, and 32-bit little endian arm as armel.
Add special cases to handle this.

File types that we don't format automatically can end up
with such basic untidiness as trailing whitespaces.
Check for these. Remove all existing precedents.
Currently we only test parsing in tools/syz-runtest
and for test OS in pkg/runtest tests.
This means errors in tests for other OSes won't be
noticed until somebody runs tests manually.
Test parsing of all tests in pkg/runtest tests.
Fix up 2 broken tests.
Introduce "manual" requirement for tests (only run if explicitly selected)
and mark f2fs tests as manual. There are too many of them.
Follow up to #2032
We now have 8 arches for Linux and .const files
produce lots of noise in PRs and lots of diffs.
If 3 .txt files are touched, the PR will have 24 .const files,
which will be intermixed with .txt files.
Frequently const values are equal across arches,
and even if they don't spreading a single value
across 8 files is inconvinient.
Merge all 8 *_arch.const files into a single .const file.
See the test for details of the new format.
The old format is still parsed for now,
we can't update all OSes at once.
For Linux this reduces number of const files/lines
from 1288/96599 to 158/11603.
Fixes#1983
We currently check from github.event.pull_request.base.sha
to github.event.pull_request.head.sha, but they may be in
different branches if the PR commits are branched not from
the latest master HEAD (at the time of PR creation).
Then GH will create a merge commit, and the range we try
to check is not valid.
Check github.event.pull_request.commits commits backwards
from github.event.pull_request.head.sha commit.
Create a struct on pkg/vcs to store data of syzkaller email recipients
and update its users. The struct contains default name, email, and a
label to divide user into To and Cc when sending the emails.

Add a udev rule to create /dev/i915, a symlink to /dev/dri/card#.
This prevents i915 related syscalls from being exercised during fuzzing
if the driver is not used.
Calls to alloc didn't respect the alignment attribute. Now
Type.Alignment() is used to ensure each type is correctly
aligned. Existing descriptions with [align[X]] don't have an
issue as they align to small blocks and default align is to
64 bytes. This commits adds support for [align[X]] for an X
larger than 64.
