Expand description
Represents a code directory blob entry.
This struct is versioned and has been extended over time.
The struct here represents a superset of all fields in all versions.
The parser will set Option<T>
fields to None
for instances
where the version is lower than the version that field was introduced in.
Fields
version: u32
Compatibility version.
flags: CodeSignatureFlags
Setup and mode flags.
code_limit: u32
Limit to main image signature range.
This is the file-level offset to stop digesting code data at.
It likely corresponds to the file-offset offset where the
embedded signature data starts in the __LINKEDIT
segment.
hash_size: u8
Size of each hash in bytes.
hash_type: DigestType
Type of hash.
platform: u8
Platform identifier. 0 if not platform binary.
page_size: u32
Page size in bytes. (stored as log u8)
spare2: u32
Unused (must be 0).
scatter_offset: Option<u32>
Offset of optional scatter vector.
spare3: Option<u32>
Unused (must be 0).
code_limit_64: Option<u64>
Limit to main image signature range, 64 bits.
exec_seg_base: Option<u64>
Offset of executable segment.
exec_seg_limit: Option<u64>
Limit of executable segment.
exec_seg_flags: Option<ExecutableSegmentFlags>
Executable segment flags.
runtime: Option<u32>
pre_encrypt_offset: Option<u32>
linkage_hash_type: Option<u8>
linkage_truncated: Option<u8>
spare4: Option<u16>
linkage_offset: Option<u32>
linkage_size: Option<u32>
ident: Cow<'a, str>
team_name: Option<Cow<'a, str>>
code_hashes: Vec<Digest<'a>>
special_hashes: HashMap<CodeSigningSlot, Digest<'a>>
Implementations
sourceimpl<'a> CodeDirectoryBlob<'a>
impl<'a> CodeDirectoryBlob<'a>
sourcepub fn adjust_version(&mut self) -> u32
pub fn adjust_version(&mut self) -> u32
Adjust the version of the data structure according to what fields are set.
Returns the old version.
sourcepub fn clear_newer_fields(&mut self)
pub fn clear_newer_fields(&mut self)
Clears optional fields that are newer than the current version.
The C structure is versioned and our Rust struct is a superset of all versions. While our serializer should omit too new fields for a given version, it is possible for some optional fields to be set when they wouldn’t get serialized.
Calling this function will set fields not present in the current version to None.
