src/groups.c, src/id.c, lib/encrypt.c, libmisc/audit_help.c,
libmisc/limits.c: Return EXIT_FAILURE instead of 1, and
EXIT_SUCCESS instead of 0.
* libmisc/audit_help.c: Replace an fprintf() by fputs().
* libmisc/audit_help.c: Remove documentation of the audit_logger
returned values. The function returns void.
* libmisc/system.c: Only return status if waitpid succeeded.
Return -1 otherwise.
* libmisc/copydir.c: Added assert to help splint.
* libmisc/copydir.c: Free allocated structures in cas of failure.
* libmisc/copydir.c: Avoid implicit conversion of pointers to
booleans.
* libmisc/copydir.c: Use buffers of size PATH_MAX instead of 1024
for filenames.
* libmisc/copydir.c: Use fchmod and fchown to change the mode of
the opened file.
* libmisc/copydir.c: Indicate the mode to open(), even if we chmod
later.
limit with getlog() / getulong(). This also means, in case of
non-PAM enabled systems, that the umask specified on the GECOS
fields should start with a 0 if specified in octal. (it used to be
force to octal). Do the appropriate cast and range checking.
* libmisc/setupenv.c: Added brackets and parenthesis.
* libmisc/setupenv.c: Ignore the return value of fclose (file
opened read-only)
* libmisc/setupenv.c: Ignore the return value of puts().
* libmisc/setupenv.c:Avoid implicit conversion of pointers to
booleans.
* libmisc/age.c: Added brackets and parenthesis.
* libmisc/age.c: Ignore the return value of fclose (file opened
read-only)
* libmisc/age.c: Ignore puts() return value.
* libmisc/age.c: Use exit(EXIT_FAILURE) instead of exit(1).
* libmisc/age.c: Avoid assignments in comparisons.
used_gids.
* libmisc/find_new_gid.c: Use getdef_ulong and cast to git_t to
get GID values.
* libmisc/find_new_gid.c: Use UL as a prefix for ulong values.
* libmisc/find_new_uid.c: Likewise.
default to 32.
* libmisc/chkname.c: Use USER_NAME_MAX_LENGTH.
* src/login.c: Use USER_NAME_MAX_LENGTH instead of the default 32.
username also needs to be bigger than USER_NAME_MAX_LENGTH because
it has to be nul-terminated.
of global utent/utxent variables. Only reuse the ut_id and maybe
the ut_host fields from utmp.
* lib/prototypes.h, libmisc/utmp.c: Removed checkutmp(),
setutmp(), setutmpx().
* lib/prototypes.h, libmisc/utmp.c: Added get_current_utmp(),
prepare_utmp(), prepare_utmpx(), setutmp(), setutmpx().
* libmisc/utmp.c (is_my_tty): Only compare the name of the utmp
line with ttyname(). (No stat of the two terminals to compare the
devices).
* libmisc/utmp.c: Use getaddrinfo() to get the address of the
host.
* configure.in: Check for getaddrinfo().
* configure.in: Use AC_CHECK_MEMBERS to check for the existence of
fields in the utmp/utmpx structures.
* configure.in: Reject systems with utmpx support but no ut_id
field in utmp. This could be fixed later if needed.
* src/login.c: Use the new utmp functions. This also simplifies
the failtmp() handling.
* src/login.c: passwd_free() renamed to pw_free() and
shadow_free() renamed to spw_free()
username as first parameter of failtmp to avoid issues with
non-null terminated ut_user, unavailability of ut_user, incomplete
username (that should not happen currently).
