NAME

getpflags, setpflags - get or set process flags
 

SYNOPSIS

#include <sys/types.h>
#include <priv.h>

uint_t getpflags(uint_t flag);

int setpflags(uint_t flag, uint_t value);

DESCRIPTION

The getpflags() and setpflags() functions obtain and modify the current per-process flags.

The following values for flag are supported:

PRIV_AWARE

This one bit flag takes the value of 0 (unset) or 1 (set). Only if this flag is set is the current process privilege-aware. A process can attempt to unset this flag but might fail silently if the observed set invariance condition cannot be met. Setting this flag is always successful. See privileges(5) for a discussion of this flag.

PRIV_DEBUG

This one bit flag takes the value of 0 (unset) or 1 (set). Only if this flag is set does the current process have privilege debugging enabled. Processes can set and unset this flag at will.

NET_MAC_AWARE
NET_MAC_AWARE_INHERIT

These flags are available only if the system is configured with Trusted Extensions. These one bit flags each take the value of 0 (unset) or 1 (set). If the NET_MAC_AWARE flag is set then the current process is allowed to communicate with peers at labels that are different than its own, subject to MAC policy.

The NET_MAC_AWARE_INHERIT flag controls the propagation of the NET_MAC_AWARE flag. When a process performs one of the exec(2) functions, the NET_MAC_AWARE flag is unset unless the NET_MAC_AWARE_INHERIT is set. NET_MAC_AWARE_INHERIT is always unset on one of the exec functions. The PRIV_NET_MAC_AWARE privilege is required to set either of these flags.

RETURN VALUES

The getpflags() returns the value associated with a given per-process flag. If the flag argument is invalid, (uint_t)-1 is returned and errno is set to indicate the error.

Upon successful completion, setpflags() returns 0. Otherwise, -1 is returned and errno is set to indicate the error.  

ERRORS

The getpflags() and setpflags() functions will fail if:

EINVAL

The value of flag or the value to which the flag is set is out of range.

The setpflags() function will fail if:

EPERM

An attempt was made to unset PRIV_AWARE but the observed set invariance condition was not met.
