The lexer (see zonecfg_lex.l) builds up tokens, which 31 * the grammar (see zonecfg_grammar.y) builds up into commands, some of 32 * which takes resources and/or properties as arguments. See the block 33 * comments near the end of zonecfg_grammar.y for how the data structures 34 * which keep track of these resources and properties are built up. 35 * 36 * The resource/property data structures are inserted into a command 37 * structure (see zonecfg.h), which also keeps track of command names, 38 * miscellaneous arguments, and function handlers. The grammar selects 39 * the appropriate function handler, each of which takes a pointer to a 40 * command structure as its sole argument, and invokes it. The grammar 41 * itself is "entered" (a la the Matrix) by yyparse(), which is called 42 * from read_input(), our main driving function. That in turn is called 43 * by one of do_interactive(), cmd_file() or one_command_at_a_time(), each 44 * of which is called from main() depending on how the program was invoked. 45 * 46 * The rest of this module consists of the various function handlers and 47 * their helper functions. Some of these functions, particularly the 48 * X_to_str() functions, which maps command, resource and property numbers 49 * to strings, are used quite liberally, as doing so results in a better 50 * program w/rt I18N, reducing the need for translation notes. 51 */ 52 53 #include <sys/mntent.h> 54 #include <sys/varargs.h> 55 #include <sys/sysmacros.h> 56 #include <sys/secflags.h> 57 58 #include <errno.h> 59 #include <fcntl.h> 60 #include <strings.h> 61 #include <unistd.h> 62 #include <ctype.h> 63 #include <stdlib.h> 64 #include <assert.h> 65 #include <sys/stat.h> 66 #include <zone.h> 67 #include <arpa/inet.h> 68 #include <netdb.h> 69 #include <locale.h> 70 #include <libintl.h> 71 #include <alloca.h> 72 #include <signal.h> 73 #include <wait.h> 74 #include <libtecla.h> 75 #include <libzfs.h> 76 #include <sys/brand.h> 77 #include <libbrand.h> 78 #include <sys/systeminfo.h> 79 #include <libdladm.h> 80 #include <libinetutil.h> 81 #include <pwd.h> 82 #include <inet/ip.h> 83 84 #include <libzonecfg.h> 85 #include "zonecfg.h" 86 87 #if !defined(TEXT_DOMAIN) /* should be defined by cc -D */ 88 #define TEXT_DOMAIN "SYS_TEST" /* Use this only if it wasn't */ 89 #endif 90 91 #define PAGER "/usr/bin/more" 92 #define EXEC_PREFIX "exec " 93 #define EXEC_LEN (strlen(EXEC_PREFIX)) 94 95 struct help { 96 uint_t cmd_num;
