2f0295373a When waiting for the parent to grant us the tty, use nanosleep 
instead of spinning to avoid hogging the CPU.

6aa43ff1e4 HAVE_DECL_GETGROUPLIST_2 is always defined if HAVE_GETGROUPLIST_2 is, 
we need to check its value, not whether it is defined.

e147ba1fec Use W_EXITCODE to construct the wait status if sudo could not execute 
the command.  Fixes the sudo exit value for exec(3) failure.

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

68c1073fe5 Rewritten sudoedit_checkdir support that checks all the dirs in the 
path and refuses to follow symlinks in writable directories.
This is a better fix for CVE-2015-5602.
Adapted from a diff by Ben Hutchings.  Bug #707

3354d27a17 Do not follow symbolic links in sudoedit by default. This behavior 
can be controlled by the sudoedit_follow Defaults flag as well as
the FOLLOW/NOFOLLOW tags.

8f9aa5af25 Need to include stddef.h to get rsize_t on Mac OS X for sudo_memset_s() 
prototype.

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

49d56f323e Add strnlen() replacement needed for glob.c. 
Only used if no glob() and no strnlen().

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.

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

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

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.

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.
