rand_addr option is the first option for the ipv6_addr union
and is just an array of 16 bytes. This option makes it easy
for trace2syz to convert ipv6 address as strace decodes
the ipv6 address as a hex string.
- Add arm64 implementations of various algorithms
(these are usually named -arm64, -neon, or -ce)
- Add missing x86 SHA-NI algorithms (sha*-ni)
- Add adiantum (new in v4.20)
- Add streebog256 (new in v4.20)
- Add streebog512 (new in v4.20)
- Add vmac64 (new in v4.19)
- Add xchacha12 (new in v4.20)
- Add xchacha20 (new in v4.20)
- Remove speck128 (was removed soon after being added to kernel)
- Remove speck64 (likewise)
- Move sm4 from hash list to cipher list
We don't specify trailing unused args for some syscalls
(e.g. ioctl that does not use its arg).
Executor always filled tailing unsed args with 0's
but pkg/csource didn't. Some such syscalls actually
check that the unsed arg is 0 and as the result failed with C repro.
We could statically check and eliminate all such cases,
but it turns out the warning fires in 1500+ cases:
a3ace5a63f/gistfile1.txt
So instead fill such args with 0's in pkg/csource too.
This adds 2 ioctls and an argument type:
- FS_IOC_ENABLE_VERITY
- FS_IOC_MEASURE_VERITY
- struct fsverity_digest
Note fs-verity on-disk structs are not yet added.
AUTO arguments can be used for:
- consts
- lens
- pointers
For const's and len's AUTO is replaced with the natural value,
addresses for AUTO pointers are allocated linearly.
This greatly simplifies writing test programs by hand
as most of the time we want these natural values.
Update tests to use AUTO.
Add bulk of checks for strict parsing mode.
Probably not complete, but we can extend then in future as needed.
Turns out we can't easily use it for serialized programs
as they omit default args and during deserialization it looks like missing args.
Over time we relaxed parsing to handle all kinds of invalid programs
(excessive/missing args, wrong types, etc).
This is useful when reading old programs from corpus.
But this is harmful for e.g. reading test inputs as they can become arbitrary outdated.
For runtests which creates additional problem of executing not
what is actually written in the test (or at least what author meant).
Add strict parsing mode that does not tolerate any errors.
For now it just checks excessive syscall arguments.
As suggested by Dmitry us a better description of the msg_flags
field, which is only used to provide information from the
kernel to the application for recvmsg() calls. This means that
the value provided is basically ignored.
Some syscalls on OpenBSD violates the ordinary SYS_ prefix convention. This is
an exhaustive enumeration of the deviations.
Regression introduced in commit 88746fdf ("pkg/csource: use defines from
sys/syscall.h on *bsd").
