Frequently it's the same condition.
In one case there is just a stray error message on console
that turns the crash into "not executing programs".
While in another case there is no stray message,
and then it's detected as "no output".
For some racy bugs syzkaller can generate a C reproducer with tun
enabled, when it's not actuallly required to trigger the bug.
Some kernel developers (that don't have CONFIG_TUN=y on their setups)
complain about such C repros.
When tun is not available, instead of exiting, print a message that tun
initialization failed and proceed.
syz-execprog doesn't utilize info about fault injections from a prog log.
Since syz-execprog is used by the repro package to reproduce crashes,
crashes caused by fault injections might not reproduce.
1. Fetch last 200K commits instead of commits for past year.
For merged commits both author date and commit date can be
arbitrary long in past (e.g. we got a commit dated by 2014).
2. Strip some commit prefixes from commits.
We have some trees where backports are prefixed with "BACKPORT:".
Previously we could no match such commits.
This is detected with newer Go toolchain:
vm/gce/gce.go:376: Errorf format %v reads arg #1, but call has only 0 args
vm/gce/gce.go:381: Errorf format %v reads arg #1, but call has only 0 args
commit 3520854be0e7 ("syz-extract: select declaring printf or not")
broke 'make extract' because it introduced invalid syntax in a text
template. Fix it.
Kernels are standalone implementations and can have their own
implementations of functions that have different prototypes than
the standard ones. In the NetBSD case the kernel printf returns
void, and it is declared in <sys/systm.h> so avoid re-declaring it.
Select if we are going to declare printf or not depending on the OS.
There is no need to specify '-' as the filename for sed(1):
- The default behavior is to read stdin
- It was not done in all places
- It breaks on NetBSD sed(1) (although I am tempted to fix it now :-)
and it does not work
Add a definition for keyctl_dh_compute(), which was added in the v4.7
kernel, then in the v4.12 kernel extended to take in an optional
'keyctl_kdf_params' argument. (Requires CONFIG_KEY_DH_OPERATIONS=y.)
Many functions in the keys API take in an ID parameter that is expected
to refer to a keyring, not to any key. Therefore, define a resource
subtype 'keyring' which can be created by add_key("keyring", ...) or by
using one of the special keyring IDs.
Also define a resource subtype 'user_key', since we'll be adding a
definition for KEYCTL_DH_COMPUTE which takes in a struct containing
"user" key IDs.
Add to key.txt all key types that currently might be present in the
kernel. It was missing a few important ones such as "asymmetric", which
has a significant attack surface since the payloads are run through an
ASN.1 decoder.
