540b09b32c Remove some compatibilty defines that should no longer be needed. 2015-07-02 09:07:15 -06:00
Todd C. Miller
8f9aa5af25 Need to include stddef.h to get rsize_t on Mac OS X for sudo_memset_s() 
prototype.

a76b93e23a Use our own bitmap macros instead of borrowing the ones from select. 2015-06-23 16:37:00 -06:00

4a07b472f0 Only include stddef.h where it is needed. 2015-06-20 05:34:35 -06:00

dc883f2454 We require ANSI C so stop using the obsolete STDC_HEADERS. 2015-06-19 14:29:27 -06:00

11840308c4 Fix sudo_strnlen() prototype. 2015-05-26 14:14:06 -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.

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

6ab5994152 Fix compilation when HAVE_DECL_SIG2STR_MAX is not defined. 2015-05-11 13:26:16 -06:00
Todd C. Miller
4ae1bdf9c3 HAVE_DECL_SIG2STR_MAX is always defined so use a !HAVE_DECL_SIG2STR_MAX 
check instead of #ifndef.
 2015-05-08 17:31:31 -06:00
Todd C. Miller
5647736ef5 Add configure check for SIG2STR_MAX, which may be missing on UnixWare. 2015-05-07 07:34:50 -06:00

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

5d2e9426b2 We cannot (easily) use clock_gettime(CLOCK_MONOTONIC) directly as 
it may be present but not implemented.  Add sudo_gettime_real() and
sudo_gettime_mono() functions to get the real and monotonic times
respectively.  Now sudo_gettime_mono() checks the value of
sysconf(_SC_MONOTONIC_CLOCK) before calling clock_gettime(CLOCK_MONOTONIC)
and falls back on sudo_gettime_real() as needed.  The Mach version
of sudo_gettime_mono() uses mach_absolute_time().

This should fix problems with timestamp files on systems where
the CLOCK_MONOTONIC is defined but not actually implemented.

01a4d6ccbf Check clock_gettime() return value and warn if it fails. 
Currently, the timestamp will be ignored if clock_gettime() fails.

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.

3eb9a854d8 Add check for getresuid() declaration, which may be missing on HP-UX. 
When checking for getdomainname() prototype, look in netdb.h too.
 2015-02-06 11:33:30 -07:00
Todd C. Miller
1bb633a210 Check whether getdomainname(), innetgr(), setresuid() and setresgid() 
are declared and add prototypes in sudo_compat.h as needed.

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

ccc210eddb If a system lacks mkdtemp() or mkstemps(), use our own mkdtemp() 
and mkstemps().  Previously we only exposed the missing one but
since the guts are the same we might as well use them.

d0cc4d9e4b Fix inet_ntop() replacement on older systems without it. 
We only expose the prototype for net_ifs.c due to the
use of socklen_t.

0f735f6581 Add function arg names to prototypes where missing. 2014-09-08 14:43:01 -06:00

daf634b728 Only include functions in util.exp that are actually in the library. 
Fixes a problem on Solaris where undefined functions that are listed
as exported in the map file result in a link error.
Also make sure we use our glob.c if the system is missing glob().

99ae71452a Replace use of HAVE_GETCWD with PREFER_PORTABLE_GETCWD. 
It is safe to assume getcwd() exists, we just need to handle broken ones.
