* su: add --group and --supp-group optionsKarel Zak2012-09-041-4/+69
| | | | | | | | | | | | | | | | | | | These options allow to specify alternative groups. The command su(1) has to be executed by root. The implementation is based on Fedora runuser(1) command. For example: # su --group=kzak --supp-group=uuidd - # id uid=0(root) gid=1000(kzak) groups=0(root),985(uuidd),1000(kzak) non-root user: $ su --group=kzak - su: only root can specify alternative groups Signed-off-by: Karel Zak <kzak@redhat.com>

(gl_DEFAULT_POSIX2_VERSION, gl_USE_SYSTEM_EXTENSIONS, gl_PERL): (gl_IGNORE_UNUSED_LIBRARIES): Remove; now done by gnulib. (gl_EARLY): Add.

(getpass): remove. * src/system.h: Include mempcpy.h, stpcpy.h, strpbrk.h.

(AM_CPPFLAGS): Don't mention -I$(srcdir), since that's now done for us. (noinst_LIBRARIES, LDDADD, DEFS): Remove. (libcoreutils_a_SOURCES): Trim down greatly, just to the files that aren't in gnulib. Remove defns gnulib does for us. * m4/check-decl.m4 (gl_CHECK_DECLS): Don't include stdio.h, string.h, stdlib.h, unistd.h, sys/time.h, time.h. Use AC_CHECK_DECLS_ONCE for free, getenv, geteuid, getlogin, getuid, lseek, malloc, memchr, realloc. Don't check for getutent, memrchr, nanosleep, stpcpy, strndup, strnlen, strstr, strtoul, strtoull.

| | | | | | | | | | | | | | | | | | | | | | the callee doesn't have to count 'em. All callers changed. Don't allocate more space for the arg vector than we'll need. Use memcpy to copy the args rather than rolling our own loop. Use size_t for sizes. (fast_startup, simulate_login, change_environment, log_su, correct_password, restricted_shell, main): Use bool for booleans. (longopts): Don't assume change_environment is an int. Use NULL, not 0, for pointers. (xsetenv): New function, replacing xputenv and concat. All callers changed. (elements): Remove; no longer needed. (log_su, correct_passwd, main): Prefer !x to x==NULL. (log_su): 2 -> STDERR_FILENO. (modify_environment, main): Don't assume that getenv's returned value has an indefinite lifetime. (modify_environment): Allocate a larger environ. (main): Remove an impossible 'case 0'; if it happens now, it'll get diagnosed. Don't assume getpwnam results outlive endpwent. Check for null or empty pw_name, pw_dir and for null pw_passwd.
* (correct_password, restricted_shell, main):Jim Meyering2004-06-011-3/+3
| | | | Prefer the notation `STREQ (a, b)' over `strcmp (a, b) == 0'.
* (usage): Use EXIT_SUCCESS, not 0, for clarity.Jim Meyering2004-01-221-9/+10
| | | | | | | (main): Initialize exit_failure to EXIT_FAIL. (main): Use EXIT_ENOENT and EXIT_CANNOT_INVOKE rather than roll-your-own symbols or integers.
* Most .c files (AUTHORS): Revert the WRITTEN_BY/AUTHORS changeJim Meyering2003-10-181-2/+2
| | | | | | | | | of 2003-09-19. Now, AUTHORS is a comma-separated list of strings. Update the call to parse_long_options so that `AUTHORS, NULL' are the last parameters. * src/true.c (main): Append NULL to version_etc argument list. * src/sys2.h (case_GETOPT_VERSION_CHAR): Likewise.
* (WRITTEN_BY): Rename from AUTHORS.Jim Meyering2003-09-191-2/+2
| | | | | Begin each WRITTEN_BY string with `Written by ' and end it with `.'. Mark each WRITTEN_BY string as translatable.
* Don't include headers already included by system.h:Jim Meyering2003-07-231-1/+0Star
| | | | Don't include closeout.h.
* (usage): Don't call close_stdout here.Jim Meyering2003-07-181-1/+2
| | | | | | | (main): Use close_stdout via atexit. Now `su --version > /dev/full' fails, as it should. Somehow, the change of 2000-05-07 that purports to fix this was not checked in.
* (main): Call initialize_main.Jim Meyering2003-06-171-0/+1

* Remove anachronistic casts of xmalloc,Jim Meyering2003-04-111-5/+5
| | | | xrealloc, and xcalloc return values and of xrealloc's first argument.
* Change `exit (0)' to `exit (EXIT_SUCCESS)',Jim Meyering2002-08-311-2/+2
| | | | | `exit (1)' to `exit (EXIT_FAILURE)', and `usage (1)' to `usage (EXIT_FAILURE)'.
* Change `error (1, ...' to `error (EXIT_FAILURE, ...'.Jim Meyering2002-08-311-5/+5

* (run_shell): Exit with status 126 or 127 when execvp orJim Meyering2002-08-011-2/+6
| | | | execv fails, for consistency with POSIX commands like env and nice.
