48c2bd0007 Declare getdelim(3) if it exists in libc but is not prototyped in stdio.h. 
This can happen on systems with a gcc packages that was built on
and older versions of the OS where getdelim(3) was not present.

d85d370c63 Add dependent system includes to make sudo_*.h more standalone. 
In the past we've relied on the various .c files to include the
system headers that define types that the sudo_*.h headers require.
This is fragile and can cause issues when includes get re-ordered.

ea1226be7c Only define WCONTINUED and WIFCONTINUED if neither are already defined. 
Fixes a warning on musl libc where WIFCONTINUED is defined in
stdlib.h for some reason.

92e42ff548 Add compatibility define for fseeko(3). 
This is better than cluttering up the code with #ifdefs for obsolete
systems.

dde86e585f Add support for building on OpenSSL 1.0.2. 
This adds compatibility defines for some OpenSSL 1.1.x functions.

3e56be3564 Store signal name, not number in I/O log timing file. 
The "SIG" prefix is not used so, e.g. SIGTERM -> "TERM".
This makes the I/O log files portable from one system to another.
Older I/O log files with signal numbers can still be replayed.

da98428e91 AIX 7.1 defines O_CLOEXEC but it can't be used outside the kernel. 
Redefine O_CLOEXEC if it doesn't fit in an int and pipe2() is missing.

10198ef6f3 Only include stdarg.h if we need it. 2018-08-22 12:36:28 -06:00
Todd C. Miller
5a0c86bb63 We still need to include string.h for AIX (and possibly others) 
when we are not using the system memset_r() function and rsize_t
is defined by the system headers.

957f284bba Add --enable-package-build to give configure a hint that we are 
building a package.  This can be used to avoid relying on libc
functions that may not be present in all libc versions for a
particular system.  For instance, AIX 7.1 may or may not have
memset_s() and getline() present.

Todd C. Miller
d9dec93277 AIX defines rsize_t in string.h, not stddef.h for use by the 
memset_s() prototype.  We use our own memset_s() on AIX since it
is not available on all BOS levels which makes package building
problematic.

0ae9662833 Add sudo_getgrouplist2() to dynamically allocate the group vector. 
This allows us to avoid repeatedly calling getgrouplist() with
a statically sized vector on macOS, Solaris, HP-UX, and AIX.

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

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.
