do_setresgid

DO_SETRESUID(9) 					   BSD Kernel Developer's Manual					   DO_SETRESUID(9)

NAME

     do_setresuid, do_setresgid -- set process uid and gid

SYNOPSIS

     #include <sys/ucred.h>

     int
     do_setresuid(struct lwp *lwp, uid_t ruid, uid_t euid, uid_t svuid, u_int flags);

     int
     do_setresgid(struct lwp *lwp, uid_t ruid, uid_t euid, uid_t svuid, u_int flags);

DESCRIPTION

     The do_setresuid and do_setresgid functions are used to implement the various system calls that allow a process to change its real, effec-
     tive, and saved uid and gid values.

     The do_setresuid function sets the specified processes real user ID to ruid, its effective user ID to euid, and its saved user ID to svuid.
     If any of the uid arguments are -1 then that assignment is skipped.

     If suser() is true, then any values may be assigned, otherwise the new uid values must match one of the existing values and the caller must
     have set the relevant bit in flags.

     The flags argument specifies which of the existing uid values the new value must match.  It should be set to a logical OR of
     ID_{R,E,S}_EQ_{R,E,S}, where ID_E_EQ_R means that it is valid to set the effective ID to the current value of the real ID.

     The do_setresgid function sets the group IDs but otherwise behaves in the same manner as do_setresuid.  The processes group list is neither
     examined nor effected.

CODE REFERENCES

     These functions are implemented in: sys/kern/kern_prot.c.

HISTORY

     Implemented for NetBSD 2.0 to replace ad-hoc code in each system call routine and in the various compat modules.
