Syzkaller syzlang syntax basics for describing ioctl syscalls.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Syzlang Ioctl Basics Syzkaller's description language (syzlang) describes syscalls for fuzzing. Description files are located at `/opt/syzkaller/sys/linux/*.txt`. ## Syscall Syntax Basic form: ``` syscall_name(arg1 type1, arg2 type2, ...) return_type ``` Specialized syscalls use `$` suffix: ``` syscall$VARIANT(args...) return_type ``` ## Common Type Patterns | Pattern | Meaning | |---------|---------| | `const[VALUE]` | Fixed constant value | | `flags[flag_set, type]` | Bitfield from flag set | | `ptr[direction, type]` | Pointer (in, out, inout) | | `intptr[min:max]` | Integer pointer with range | | `int8`, `int16`, `int32` | Fixed-size integers | | `int16be`, `int32be` | Big-endian integers | | `array[type]` | Variable-length array | | `array[type, count]` | Fixed-length array | ## Ioctl Patterns For ioctls with output: ``` ioctl$CMD(fd fd_type, cmd const[CMD], arg ptr[out, int32]) ``` For ioctls with input: ``` ioctl$CMD(fd fd_type, cmd const[CMD], arg ptr[in, struct_type]) ``` For simple value ioctls: ``` ioctl$CMD(fd fd_type, cmd const[CMD], arg intptr[0:1]) ``` For ioctls using ifreq structure (from socket.txt): ``` …

How to install
mdr add benchflow-ai/benchflow/syzlang-ioctl-basics@sha256:f733ad59a34b426dThe line at the top of this page pins the label git:20260610.e2a435f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
