b20b411e71 Define NO_LEAKS when sudo is built with Coverity. 2016-05-04 13:01:57 -06:00
Todd C. Miller
e0f12d81a7 Remove configure checks for dev_t, id_t, ino_t, ptrdiff_t, size_t
and ssize_t.  These have been specified by either ANSI C or POSIX
for long enough that if the system doesn't support them, it is
unlikely to be able to compile sudo anyway.

48dff84081 Work around an ambiguity in the PAM spec with respect to the conversation
function.  It is not clear whether the "struct pam_message **msg" is an
array of pointers or a pointer to an array.  Linux-PAM and OpenPAM use
an array of pointers while Solaris/HP-UX/AIX uses a pointer to an array.
Bug #726.

41a32a1c58 When calling setauthdb(), save the old registry value so we can
restore it properly.  Previously we were setting the registry to
unrestricted instead of actually restoring it.

c1b1481204 Use faccessat(2) for directory writability instead of doing the
checks manually where possible.  This also allows us to remove the
#ifdef __linux__ bits since we no longer use fstat(2) on Linux with
an O_PATH fd.

4bcef637f8 Work around the buggy pread(2) on 32-bit HP-UX 11.00 by using
pread64() on that platform.

c50cead833 Add directory writability checks for sudoedit. 2015-10-23 14:04:35 -06:00

37abc1b7e4 There's no point in trying to interpose protected versions of the
exec family of functions.  Many modern C libraries use hidden symbols
for the functions and syscalls defined in libc such that they cannot
be overridden inside libc itself.  We have to just wrap all the exec
variants plus system and popen.

a2979ed809 Remove checks for __sys_siglist and __sys_signame. They are internal
to libc and there are no known systems that export those symbols
that do not already export the single underbar or no-underbar versions.

67183d74f4 Remove include/compat/timespec.h. Systems old enough to lack struct
timespec are too old to build a modern sudo.

7d0a623fdd Use pread(2) and pwrite(2) where possible. 2015-09-07 06:06:08 -06:00

00142c91fa Lock individual records in the timestamp file instead of the entire
file.  This will make it possible for multiple sudo processes using
the same tty to serialize their timestamp lookups.

43a57126ea Solaris 2.6 has the prototypes for inet_pton() and inet_ntop() in
resolv.h.

d77941c2be We require POSIX so no need to conditionally include dirent.h.
Add a check for d_namlen and use the result in the NAMLEN macro.

d87a0a4aab Add check for inline support. 2015-06-30 10:16:56 -06:00

09b07fe21a Add back _REENTRANT define on HP-UX to expose strtok_r on some versions.
We may need to define it on other systems too.

a50555faa2 Remove support for the obsolete malloc.h header. 2015-06-18 20:30:59 -06:00

138aa2ccd1 Remove BROKEN_SYSLOG define which was for obsolete versions of HP-UX.
Remove last remnants of 4.2BSD syslog support.

a38253b101 Replace use of OSDEFS with config.h defines.
Rename DEFS in Makefile.in to CPPDEFS and include in CPPFLAGS.
Bring back _BSD_SOURCE as a config.h define.
Remove obsolescent _REENTRANT define.

4c7a264f10 Use AC_FUNC_STRNLEN to check for broken strnlen() on AIX.
This requires that we use AC_USE_SYSTEM_EXTENSIONS so remove
things from OSDEFS that are enabled by AC_USE_SYSTEM_EXTENSIONS.
2015-06-17 17:00:21 -06:00
Todd C. Miller
82286d8b7b Add strndup() for those without it. As strndup.c uses strnlen(),
use our own if it is missing.
2015-05-26 14:05:26 -06:00
Todd C. Miller
49d56f323e Add strnlen() replacement needed for glob.c.
Only used if no glob() and no strnlen().

05a01d4c5d Avoid using a leading underbar in defines as they are reserved in
ISO C.

a40cf3e288 There should be no need to check for tzset() as it is POSIX. 2015-05-18 13:42:06 -06:00

3595807f4e Add reallocarray() for those without it. 2015-05-14 10:13:18 -06:00

8bc70a635c Instead of trying to make weak functions work on all platforms,
just use a registration function for a plugin-specific setlocale
function.  The sudoers version just wraps sudoers_setlocale().

5647736ef5 Add configure check for SIG2STR_MAX, which may be missing on UnixWare. 2015-05-07 07:34:50 -06:00

a7edf7d984 Remove compat/utime.h, it was only useful for ancient systems that
are no longer capable of compiling sudo.
2015-03-03 16:57:55 -07:00

ee72cba937 Use futimens() and utimensat() instead of futimes() and utimes(). 2015-03-02 13:58:50 -07:00

b5831d55d8 Update snprintf.c from OpenBSD. The floating point and wide character
code has been retained but is not compiled by default.

be8dbeb22e Avoid using HOST_NAME_MAX directly and use sysconf(_SC_HOST_NAME_MAX)
instead.
2015-02-19 20:28:02 -07:00
Todd C. Miller
96eddddc12 Almost no systems actually define OPEN_MAX since it is dynamic on
modern OSes.  If sysconf(_SC_OPEN_MAX) ever fails, fall back on
_POSIX_OPEN_MAX instead.  We can assume modern systems have sysconf().
Also remove checks for strrchr() and strtoll() for which the HAVE_*
defines are no longer used.
2015-02-19 09:59:25 -07:00
Todd C. Miller
166db8eeb4 Use weak symbols for sudo_warn_gettext() and sudo_warn_strerror()
so distros using "-Wl,--no-undefined" in LDFLAGS don't run into
problems.

3eb9a854d8 Add check for getresuid() declaration, which may be missing on HP-UX.
When checking for getdomainname() prototype, look in netdb.h too.

Todd C. Miller
88f79588e0 Remove configure checks for strrchr() and strtoll() for which the

Todd C. Miller
1bb633a210 Check whether getdomainname(), innetgr(), setresuid() and setresgid()
are declared and add prototypes in sudo_compat.h as needed.

f2a554f297 Add missing prototypes for usrinfo() and setauthdb() for AIX. 2015-02-03 07:33:25 -07:00
Todd C. Miller
536c83cec3 Solaris uses sysinfo(SI_SRPC_DOMAIN) instead of getdomainname() to
get the host's NIS domain.

55a34e6941 Avoid inadvertantly defining things like PATH_MAX simply because
the source file doesn't include limits.h.

2040d4dde5 Use arc4random() for mkstemp/mkdtemp if available. If not, try to
seed from /dev/urandom before falling back to the gettimeofday seed.
2014-10-31 06:57:19 -06:00
Todd C. Miller
5f9e84ea51 Use inet_ntop() instead of inet_ntoa() and include a version for
systems that are missing it.
2014-10-02 07:55:08 -06:00

99ae71452a Replace use of HAVE_GETCWD with PREFER_PORTABLE_GETCWD.
It is safe to assume getcwd() exists, we just need to handle broken ones.
2014-07-28 16:36:43 -06:00
Todd C. Miller
b0a09fb671 Add check for inet_ntoa() since it may live in libnsl.
Make getcwd() replacement private to the SunOS 4 section.

Todd C. Miller
96d1967ab0 Avoid passing -no-fast-install to libtool as this results in the
build dir being left in the library path of the installed executable.
Instead, we remove the "lt-" prefix from the program name in
initprogname() so that the regress test output is unaffected by
libtool's binary wrapper.

18dbc52e4b Add Solaris audit support; from Gary Winiger at Oracle. 2014-06-27 16:01:40 -06:00
Todd C. Miller
87c2fe5a31 Prefix all libc replacements with sudo_ and #define the real name
to the sudo_ version.  That way we don't pollute the libc namespace.

218aa1e598 Move the sha2 code into libreplace and add configure checks for
SHA224Update in libc and libmd.  Solaris uses "void *" where we use
"unsigned char *" so we need a check for that too.  Solaris sha2.h
defines SHA224, SHA256, SHA384, and SHA512 so rename those tokens.
Adapted from changes from Vladimir Marek in bug #641.
