Module prctl

prctl is a Linux-only API for performing operations on a process or thread.

Note that careless use of some prctl() operations can confuse the user-space run-time environment, so these operations should be used with care.

For more documentation, please read prctl(2).

Enums

PrctlMCEKillPolicy

The type of hardware memory corruption kill policy for the thread.

Functions

clear_mce_kill

Clear the thread memory corruption kill policy and use the system-wide default

get_child_subreaper

Get the “child subreaper” attribute for this process

get_dumpable

Get the dumpable attribute for this process.

get_keepcaps

Get the “keep capabilities” attribute for this process

get_mce_kill

Get the thread memory corruption kill policy

get_name

Return the name of the calling thread

get_no_new_privs

Get the “no new privs” attribute for the calling thread.

get_pdeathsig

Returns the current parent-death signal

get_thp_disable

Get the “THP disable” flag for the calling thread.

get_timerslack

Get the timerslack for the calling thread.

set_child_subreaper

Set the “child subreaper” attribute for this process

set_dumpable

Set the dumpable attribute which determines if core dumps are created for this process.

set_keepcaps

Set the “keep capabilities” attribute for this process. This causes the thread to retain capabilities even if it switches its UID to a nonzero value.

set_mce_kill

Set the thread memory corruption kill policy

set_name

Set the name of the calling thread. Strings longer than 15 bytes will be truncated.

set_no_new_privs

Set the calling threads “no new privs” attribute. Once set this option can not be unset.

set_pdeathsig

Set the parent-death signal of the calling process. This is the signal that the calling process will get when its parent dies.

set_thp_disable

Set the state of the “THP disable” flag for the calling thread. Setting this disables transparent huge pages.

set_timerslack

Sets the timer slack value for the calling thread. Timer slack is used by the kernel to group timer expirations and make them the supplied amount of nanoseconds late.

set_vma_anon_name

Set an identifier (or reset it) to the address memory range.

task_perf_events_disable

Disable all performance counters attached to the calling process.

task_perf_events_enable

Enable all performance counters attached to the calling process.
