Struct selinux::context_restore::RestoreFlags

pub struct RestoreFlags { /* fields omitted */ }

Flags controlling relabeling operations.

Implementations

impl RestoreFlags

pub const IGNORE_DIGEST: RestoreFlags

Force the checking of labels even if the stored SHA1 digest matches the specfile entries SHA1 digest.

The specfile entries digest will be written to the security.sehash extended attribute once relabeling has been completed successfully provided the NO_CHANGE flag has not been set.

pub const NO_CHANGE: RestoreFlags

Don’t change any file labels (passive check) or update the digest in the security.sehash extended attribute.

pub const SET_SPEC_FILE_CTX: RestoreFlags

If set, reset the files label to match the default spec file context. If not set only reset the files “type” component of the context to match the default spec file context.

pub const RECURSE: RestoreFlags

Change file and directory labels recursively (descend directories) and if successful write an SHA1 digest of the spec file entries to an extended attribute.

pub const VERBOSE: RestoreFlags

Log file label changes.

Note that if VERBOSE and PROGRESS flags are set, then PROGRESS will take precedence.

pub const PROGRESS: RestoreFlags

Show progress by outputting the number of files in 1k blocks processed to stdout.

If the MASS_RELABEL flag is also set then the approximate percentage complete will be shown.

pub const REAL_PATH: RestoreFlags

Convert passed-in path name to the canonical path name using realpath().

pub const XDEV: RestoreFlags

Prevent descending into directories that have a different device number than the path name entry from which the descent began.

pub const ADD_ASSOC: RestoreFlags

Attempt to add an association between an inode and a specification. If there is already an association for the inode and it conflicts with the specification, then use the last matching specification.

pub const ABORT_ON_ERROR: RestoreFlags

Abort on errors during the file tree walk.

pub const SYS_LOG_CHANGES: RestoreFlags

Log any label changes to syslog().

pub const LOG_MATCHES: RestoreFlags

Log what spec file context matched each file.

pub const IGNORE_NO_ENTRY: RestoreFlags

Ignore files that do not exist.

pub const IGNORE_MOUNTS: RestoreFlags

Do not read /proc/mounts to obtain a list of non-seclabel mounts to be excluded from relabeling checks.

Setting IGNORE_MOUNTS is useful where there is a non-seclabel fs mounted with a seclabel fs mounted on a directory below this.

pub const MASS_RELABEL: RestoreFlags

Generally set when relabeling the entire OS, that will then show the approximate percentage complete.

The PROGRESS flag must also be set.

pub const SKIP_DIGEST: RestoreFlags

Do not check or update any extended attribute security.sehash entries.

This flag is supported only by libselinux version 3.0 or later.

pub const CONFLICT_ERROR: RestoreFlags

Treat conflicting specifications, such as where two hardlinks for the same inode have different contexts, as errors.

This flag is supported only by libselinux version 3.1 or later.

pub const fn empty() -> RestoreFlags

Returns an empty set of flags

pub const fn all() -> RestoreFlags

Returns the set containing all flags.

pub const fn bits(&self) -> c_uint

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: c_uint) -> Option<RestoreFlags>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: c_uint) -> RestoreFlags

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const unsafe fn from_bits_unchecked(bits: c_uint) -> RestoreFlags

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: RestoreFlags) -> bool

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: RestoreFlags) -> bool

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: RestoreFlags)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: RestoreFlags)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: RestoreFlags)

Toggles the specified flags in-place.

pub fn set(&mut self, other: RestoreFlags, value: bool)

Inserts or removes the specified flags depending on the passed value.
