|
Control the address space model to be used by the kernel. Possible values for mode are | +as mode |
default, share_magic, exec_magic, shmem_magic, and mpas. The default value is |
|
currently equivalent to share_magic. In order to set the mode to any value other than |
|
the default, the binary must be built with the |
|
and data segments are contiguous. |
|
|
|
Control whether the embedded path list stored when the program (if any) was built can | +b flag |
be used to locate shared libraries needed by the program. The two flag values, enable |
|
and disable, respectively enable and disable use of the embedded path list. However, |
|
you cannot use disable on an ELF file, and a warning message is issued. If +b enable |
|
and +s enable are both specified, the order in which they appear determines which |
|
search path is used first. See the +s option. |
|
|
|
Format 2 only: Enable or disable the code bit for a specified segment. If this is enabled, | +c flag |
it is denoted by the +c flag for the segment listing in the chatr output. |
|
|
|
Enable or disable the code bit for the file's data segment(s). If this is enabled, it is denoted | +cd flag |
by the +c flag for the segment listing in the chatr output. |
|
|
|
Enable or disable the code bit for the file's text segments(s). If this is enabled, it is denoted | +ci flag |
by the +c flag for the segment listing. |
|
|
|
Enable or disable the ability to run a program, and, after it is running, attach to it with a | +dbg flag |
debugger and set breakpoints in its dependent shared libraries. For shared libraries, this |
|
flag makes the text segment mapped private and writable. |
|
|
|
Format 2 only: Enable or disable lazy swap allocation for dynamically allocated segments | +dz flag |
(such as the stack or heap). |
|
|
|
Control the ability of user code to execute from stack with the flag values, enable and | +es flag |
disable. See the "Restricting Execute Permission on Stacks" section of the chatr(1) |
|
manpage for additional information related to security issues. |
|
|
|
Control whether the global symbol table hash mechanism is used to look up values of | +gst flag |
symbol import/export entries. The two flag values, enable and disable, respectively enable |
|
and disable use of the global symbol table hash mechanism. The default is disable. |
|
|
|
Request a particular hash array size using the global symbol table hash mechanism. The | +gstsize size |
value can vary between 1 and MAXINT. The default value is 1103. Use this option with |
|
+gst enable. This option works on files linked with the +gst option. |
|
|
|
Controls the preference of physical memory for the data segment. This is important only | +id flag |
on ccNUMA (Coherent |
|
be either enable or disable. When enabled, the data segment uses interleaved memory. |
|
When disabled (the default), the data segment uses cell local memory. This behavior is |
|
inherited across a fork() but not an exec. For more information on ccNUMA, see |
|
pstat_getlocality(2). |
|
|
|
Request kernel assisted branch prediction. The flags, enable and disable, turn this request | +k flag |
on and off, respectively. |
|
|
|
Do not subject a library to path list lookup, even if path lists are provided. That is, use | +l libname |
default library path stored in the executable. |
|
|
|
Format 2 only: Enable or disable the modification bit for a specified segment. If this is | +m flag |
enabled, it is denoted by the +m flag for the segment listing in the chatr output. |
