Because \fBgetexecattr()\fR always +returns a single entry, the \fBnext\fR pointer in the \fBexecattr_t\fR data +structure points to \fINULL\fR. +.sp +.LP +The internal representation of an \fBexec_attr\fR entry is an \fBexecattr_t\fR +structure defined in <\fBexec_attr.h\fR> with the following members: +.sp +.in +2 +.nf +char *name; /* name of the profile */ +char *type; /* type of profile */ +char *policy; /* policy under which the attributes are */ + /* relevant*/ +char *res1; /* reserved for future use */ +char *res2; /* reserved for future use */ +char *id; /* unique identifier */ +kva_t *attr; /* attributes */ +struct execattr_s *next; /* optional pointer to next profile */ +.fi +.in -2 + +.sp +.LP +The \fBfree_execattr()\fR function releases memory. It follows the \fBnext\fR +pointers in the \fBexecattr_t\fR structure so that the entire linked list is +released. +.sp +.LP +The \fBsetexecattr()\fR function "rewinds" to the beginning of the enumeration +of \fBexec_attr\fR entries. Calls to \fBgetexecuser()\fR can leave the +enumeration in an indeterminate state. Therefore, \fBsetexecattr()\fR should be +called before the first call to \fBgetexecattr()\fR. +.sp +.LP +The \fBendexecattr()\fR function can be called to indicate that \fBexec_attr\fR +processing is complete; the library can then close any open \fBexec_attr\fR +file, deallocate any internal storage, and so forth. +.sp +.LP +The \fBgetexecuser()\fR function returns a linked list of entries that match +the \fItype\fR and \fIid\fR arguments and have a profile that has been assigned +to the user specified by \fIusername\fR, as described in \fBpasswd\fR(4). +Profiles for the user are obtained from the list of default profiles in +\fB/etc/security/policy.conf\fR (see \fBpolicy.conf\fR(4)) and the +\fBuser_attr\fR(4) database. Only entries in the name service scope for which +the corresponding profile entry is found in the \fBprof_attr\fR(4) database are +returned. +.sp +.LP +The \fBgetexecprof()\fR function returns a linked list of entries that match +the \fItype\fR and \fIid\fR arguments and have the profile specified by the +\fIprofname\fR argument. Only entries in the name service scope for which the +corresponding profile entry is found in the \fBprof_attr\fR database are +returned. +.sp +.LP +Using \fBgetexecuser()\fR and \fBgetexecprof()\fR, programmers can search for +any \fItype\fR argument, such as the manifest constant \fBKV_COMMAND\fR. The +arguments are logically AND-ed together so that only entries exactly matching +all of the arguments are returned. Wildcard matching applies if there is no +exact match for an \fBID\fR. Any argument can be assigned the \fINULL\fR value +to indicate that it is not used as part of the matching criteria. The \fB\fR +search_flag controls whether the function returns the first match +(\fBGET_ONE\fR), setting the \fBnext\fR pointer to \fINULL\fR or all matching +entries (\fBGET_ALL\fR), using the \fBnext\fR pointer to create a linked list +of all entries that meet the search criteria. See \fBEXAMPLES\fR. +.sp +.LP +Once a list of entries is returned by \fBgetexecuser()\fR or +\fBgetexecprof()\fR, the convenience function \fBmatch_execattr()\fR can be +used to identify an individual entry. It returns a pointer to the individual +element with the same profile name ( \fIprofname\fR), type name ( \fItype\fR), +and \fIid\fR. Function parameters set to \fINULL\fR are not used as part of the +matching criteria. In the event that multiple entries meet the matching +criteria, only a pointer to the first entry is returned. The +\fBkva_match\fR(3SECDB) function can be used to look up a key in a key-value +array. +.SH RETURN VALUES +.sp +.LP +Those functions returning data only return data related to the active policy. +The \fBgetexecattr()\fR function returns a pointer to a \fBexecattr_t\fR if it +successfully enumerates an entry; otherwise it returns \fINULL\fR, indicating +the end of the enumeration. +.SH USAGE +.sp +.LP +The \fBgetexecattr()\fR, \fBgetexecuser()\fR, and \fBgetexecprof()\fR functions +all allocate memory for the pointers they return. This memory should be +deallocated with the \fBfree_execattr()\fR call. The \fBmatch_execattr()\fR( +function does not allocate any memory. Therefore, pointers returned by this +function should not be deallocated. +.sp +.LP +Individual attributes may be referenced in the \fBattr\fR structure by calling +the \fBkva_match\fR(3SECDB) function. +.SH EXAMPLES +.LP +\fBExample 1 \fRFind all profiles that have the \fBping\fR command. +.sp +.in +2 +.nf +if ((execprof=getexecprof(NULL, KV_COMMAND, "/usr/sbin/ping", + GET_ONE)) == NULL) { + /* do error */ +} +.fi +.in -2 + +.LP +\fBExample 2 \fRFind the entry for the \fBping\fR command in the Network +Administration Profile. +.sp +.in +2 +.nf +if ((execprof=getexecprof("Network Administration", KV_COMMAND, + "/usr/sbin/ping", GET_ALL))==NULL) { + /* do error */ +} +.fi +.in -2 + +.LP +\fBExample 3 \fRTell everything that can be done in the Filesystem Security +profile. +.sp +.in +2 +.nf +if ((execprof=getexecprof("Filesystem Security", KV_NULL, NULL, + GET_ALL))==NULL)) { + /* do error */ +} +.fi +.in -2 + +.LP +\fBExample 4 \fRTell if the \fBtar\fR utility is in a profile assigned to user +wetmore.
