syscalls = { version = "0.3", default-features = false }

with-serde

Various types can be serialized with Serde. This can be enabled with:

syscalls = { version = "0.3", features = ["with-serde"] }

Updating the syscall list

Updates are pulled from the .tbl files in the Linux source tree.

  1. Change the Linux version in syscalls-gen/src/main.rs to the latest version. Using a release candidate version is OK.
  2. Run cd syscalls-gen && cargo run. This will regenerate the syscall tables in src/arch/.
