ends up as c99 variable-sized local arrays (CMSG_SPACE() uses a function
as part of calculating its result). This causes the stack protection
code in the compiler to complain, so build this one with -fno-stack-protector
to avoid the problem.
Gets us back to buildability for this program for a number of our ports.
FORTIFY_SOURCE feature of libssp, thus checking the size of arguments to
various string and memory copy and set functions (as well as a few system
calls and other miscellany) where known at function entry. RedHat has
evidently built all "core system packages" with this option for some time.
This option should be used at the top of Makefiles (or Makefile.inc where
this is used for subdirectories) but after any setting of LIB.
This is only useful for userland code, and cannot be used in libc or in
any code which includes the libc internals, because it overrides certain
libc functions with macros. Some effort has been made to make USE_FORT=yes
work correctly for a full-system build by having the bsd.sys.mk logic
disable the feature where it should not be used (libc, libssp iteself,
the kernel) but no attempt has been made to build the entire system with
USE_FORT and doing so will doubtless expose numerous bugs and misfeatures.
Adjust the system build so that all programs and libraries that are setuid,
directly handle network data (including serial comm data), perform
authentication, or appear likely to have (or have a history of having)
data-driven bugs (e.g. file(1)) are built with USE_FORT=yes by default,
with the exception of libc, which cannot use USE_FORT and thus uses
only USE_SSP by default. Tested on i386 with no ill results; USE_FORT=no
per-directory or in a system build will disable if desired.
with MKPIC=no, possibly because the target does not support shared
libraries, these include libraries required to resolve all symbols
which end up referenced from PAM-using applications. The libraries
presently required are -lcrypt, -lrpcsvc and -lutil.
Add use of these variables which are currently set up to use PAM,
so that they compile when MKPIC=no.
Also, in the telnetd case, reorder the order of the libraries, so
that libtelnet.a comes before -ltermcap and -lutil, again to fix
link error when MKPIC=no.
Discussed with thorpej and christos.
"dereferencing type-punned pointer will break strict-aliasing rules"
which occurs when compiling crypto_openssl.c with -O[23s].
This should be gone once a new release of kame with a fix applied
is imported.
be changed in the future to "yes".
If MKDYNAMICROOT == "no", there is no change from existing behaviour
of a static /bin and /sbin (and a few programs in elsewhere).
If MKDYNAMICROOT == "yes", the following changes occur:
in <bsd.own.mk>:
SHLIBDIR?= /lib
SHLINKDIR?= /lib
in various Makefiles, the following entry is DISABLED.
LDSTATIC?=-static
This results in all programs (except those "standalone" programs built
in sys/arch/*/stand) are linked dynamically, the shared linker is moved
from /usr/libexec to /lib (with a compat symlink), and the shared
libraries used by /bin and /sbin programs are moved from /usr/lib to
/lib (with compat symlinks).
file descriptor leak fix.
null encryption algorithm key length fix (should use 0).
couple of null-pointer reference fixes.
set port # to 500 in ID payload (possible interop issue - spec is unclear).
correctly match address pair on informational exchange
infrastructure and using that infrastructure in programs.
* MKHESIOD, MKKERBEROS, MKSKEY, and MKYP control building
of the infratsructure (libraries, support programs, etc.)
* USE_HESIOD, USE_KERBEROS, USE_SKEY, and USE_YP control
building of support for using the corresponding API
in various libraries/programs that can use it.
As discussed on tech-toolchain.
- make a copy of cfparse.y called "y.tab.y" because "cfparse.h" is not
actually the yacc generated header file (duh?)
- include the tcpdump directory with -I *after* racoon's source, else
tcpdump's headers will be picked up unexpectedly
- include . *before* racoon's source so as to make the generated files
first on the list
