Enum libseccomp::ScmpAction

#[non_exhaustive]
pub enum ScmpAction {
    KillProcess,
    KillThread,
    Trap,
    Notify,
    Errno(i32),
    Trace(u16),
    Log,
    Allow,
}

Represents an action to be taken on a filter rule match in the libseccomp.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

KillProcess

Kills the process.

KillThread

Kills the thread.

Trap

Throws a SIGSYS signal.

Notify

Triggers a userspace notification. NOTE: This action is only usable when the libseccomp API level 6 or higher is supported.

Errno(i32)

Returns the specified error code. NOTE: You can only use integers from 0 to u16::MAX.

Trace(u16)

Notifies a tracing process with the specified value.

Log

Allows the syscall to be executed after the action has been logged.

Allow

Allows the syscall to be executed.

Implementations

impl ScmpAction

pub fn from_str(action: &str, val: Option<i32>) -> Result<Self, SeccompError>

Converts string seccomp action to ScmpAction.

Arguments

• action - A string action, e.g. SCMP_ACT_*.

See the seccomp_rule_add(3) man page for details on valid action values.

Errors

If an invalid action is specified or a value on "SCMP_ACT_TRACE" is not in the range from 0 to u16::MAX, an error will be returned.

Trait Implementations

impl Clone for ScmpAction

fn clone(&self) -> ScmpAction

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ScmpAction

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for ScmpAction

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,

Feeds a slice of this type into the given Hasher.

impl PartialEq<ScmpAction> for ScmpAction

fn eq(&self, other: &ScmpAction) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
