70aef0eb2d sudo_debug_register: add minfd argument to specify lowest fd number 
Use this in sudo_intercept.so to avoid allocating a low-numbered
fd which the shell reserves for use by scripts.

a12b15b436 lib: util: Makefile.in: use host CFLAGS and CPPFLAGS for mksig{name,list} 
When cross-build support was added for mkig{name,list} was added, the
CFLAGS and CPPFLAGS should have been updated to the HOSTCFLAGS/HOSTCPPFLAGS
vars.

In a cross-build scenario, some of these flags don't match what the
compiler can understand (because they may be architecture specific) and
may fail the build.

Using the HOSTCFLAGS/HOSTCPPFLAGS works and builds successfully.
Also the output binary works on the target.

This is in continuation of
- https://github.com/sudo-project/sudo/pull/104
- https://github.com/sudo-project/sudo/pull/109

b40f74cb24 Cross-build support for mksigname and mksiglist 
We must build these with the host C compiler but use the target
preprocessor to generate the output.

ef91b90ad6 Sync siglist.in with the generated files. 
The change to prefer SIGSYS over SIGUNUSED wasn't made to siglist.in.
Also, mksigname.c doesn't need to explicitly set sudo_sys_signame[0].

c5247845ac Add NSS_TRYAGAIN and correct buflen in struct nss_XbyY_buf_t. 
Add some function argument names.  Also use struct nss_db_state *
instead of void * in nss_db_root_t.  We don't define struct
nss_db_state but since it is a pointer all we need is a forward
declaration.

b913a832e8 Make sure we link with libsudo_util *after* libfuzzstub. 
This only affects builds with a static libsudo_util.
Also fix a warning on HP-UX about main not being public.

3104d8ba0b Make sure we don't read or write past the end of the group buffer. 
We need to leave room for the terminating NULL in gr_mem.
It is possible for gbm->numgids > gbm->maxgids if we ran out of room.

4c182c90f1 Rename "fuzz" makefile target to "check-fuzzer". 
It's purpose is to run the fuzzers are part of a normal "make check"
to avoid bit rot, not to perform a fuzzer run.
The fuzz_logsrvd_conf fuzzer was not wired up to "make check" previously.

d9d450292d Remove compatibility defines for POSIX sys/stat.h macros. 
Modern systems have them and we no longer support pre-POSIX systems.
This fixes potential redefinition of the macros if sys/stat.h is
included after sudo_compat.h.  Bug #968.

non-local groups via getgroups(2), even when _DARWIN_UNLIMITED_GETGROUPS
is defined.  Bug #946.

and TLS support is enabled.

387169ac67 Add support on AIX for loading plugins that are .a (not .so) files. 
It is possible to specify the member name in parens after the path,
e.g. sudoers.a(shr.o) for 32-bit or sudoers.a(shr_64.o) for 64-bit.
If no member is specified in the path and dlopen() fails with ENOEXEC,
try again with an explicit member, either shr.o or shr_64.o.

a7e2dd15e1 Test the error case by closing the underlying fd. 
Note that we don't use ferror() here since our getdelim() has no
way to set the error flag if there is a memory allocation error.
