Implementations

impl Personality

pub const UNAME26: Self

Have uname(2) report a 2.6.40+ version number rather than a 3.x version number. Added as a stopgap measure to support broken applications that could not handle the kernel version- numbering switch from 2.6.x to 3.x.

pub const ADDR_NO_RANDOMIZE: Self

With this flag set, disable address-space-layout randomization.

pub const FDPIC_FUNCPTRS: Self

User-space function pointers to signal handlers point (on certain architectures) to descriptors.

pub const MMAP_PAGE_ZERO: Self

Map page 0 as read-only (to support binaries that depend on this SVr4 behavior).

pub const ADDR_COMPAT_LAYOUT: Self

With this flag set, provide legacy virtual address space layout.

pub const READ_IMPLIES_EXEC: Self

With this flag set, PROT_READ implies PROT_EXEC for mmap(2).

pub const ADDR_LIMIT_32BIT: Self

Limit the address space to 32 bits.

pub const SHORT_INODE: Self

No effects(?).

pub const WHOLE_SECONDS: Self

No effects(?).

pub const STICKY_TIMEOUTS: Self

With this flag set, select(2), pselect(2), and ppoll(2) do not modify the returned timeout argument when interrupted by a signal handler.

pub const ADDR_LIMIT_3GB: Self

With this flag set, use 0xC0000000 as the offset at which to search a virtual memory chunk on mmap(2); otherwise use 0xFFFFE000.

pub const PER_XENIX: Self

Implies STICKY_TIMEOUTS and SHORT_INODE; otherwise no effects.

pub const PER_LINUX32: Self

[To be documented.]

pub const PER_LINUX32_3GB: Self

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl Personality

pub const fn iter(&self) -> Iter<Personality>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
