RAppArmor (version 0.8.1)

rlimit_stack: Limit stack size.

Description

Limits the maximum size of the process stack, in bytes.

Usage

rlimit_stack(hardlim, softlim = hardlim, pid = 0,
    verbose = FALSE)

Arguments

hardlim

size of stack

softlim

size of stack

pid

id of the target process

verbose

print some C output (TRUE/FALSE)

Details

The maximum size of the process stack, in bytes. Upon reaching this limit, a SIGSEGV signal is generated. To handle this signal, a process must employ an alternate signal stack (sigaltstack(2)). Since Linux 2.6.23, this limit also determines the amount of space used for the process's command-line arguments and environment variables; for details, see execve(2).
