Instead of allocating a static amount of memory for the data
structures via valloc() in allocsys(), allocate things dynamically
using pool(9) when possible and malloc(9) when not. The various
members of struct seminfo and struct shminfo are in kern.seminfo
and kern.shminfo respectively (not all members of kern.seminfo are
changable).
The data structures used still leave something to be desired but
things are not made worse in that respect by this commit.

sparc64. Change cast back to unsigned char but do a bitwise AND
with 0xff to avoid any sign extension weirdness and to make it
impossible for us to overflow _C_ctype_. The bitwise AND is probably
not needed and may be removed later if this does not trigger compiler bugs.

that affects both the libc and inline versions identically.

100% identical to what is in libc.
Discussed with pjanzen@ and OK'd by deraadt@.

code that assign a u_int value to x_handy. However, this means
that we need to be careful checking for overflow as we can no longer
subtract a value and check the result for < 0. We reorder the
expression instead to avoid this problem (basic algebra).

it is not the fist character of optstring (since that would conflict
with GNU semantics).
Update the bit on "W;" within optstring when called as getopt (not
getopt_long) to current reality.

as shortcuts for long ones, but only if this would not conflict with
a short option in optstring. Now binutils gas works.

We don't want to use the sysctl() by default since we are reading more
than just a few bytes of entropy when setting up the state.

o Check for long options even when not at the beginning of an option.
For instance, if -a is a short option w/o an arg and -static is a
boolean long option then -astatic is valid for getopt_long_only().
o If a potential long argument does not match longopts and the first
character is not a short option, print a warning and skip the rest
of the argument.
Also clean up some trailing whitespace and change return value of
parse_long_options() from -2 to -1 when unmatched and in long_only mode.
With these fixes the binutils ld seems happy with our getopt_long_only()
|
|
is in optstring.
|
|
In order for getopt_only_only() to work we need to check for long
options before short ones. I have merged getopt_internal and
getopt_long_internal into a single function with the actual long
args parsing broken out into a separate function.
This also simplifies the flow of control.

getopt_long_only(). At some point this should replace the BSD
getopt(3) but we are not there yet.
While I am here add protection from the multiple getopt() definitions
due to conflicting standards.

now build libraries with propolice enabled. Without this, existing
binaries (such as ports/packages) that link with any system library
other than libc will fail with an undefined symbol of "___guard"
(__guard on ELF).

attack protection scheme, into gcc.
This protection is enabled by default. It can be turned off by using the
-fno-stack-protector flag.
Code by Hiroaki Etoh (etoh at jp dot ibm dot com); work on openbsd-specific
integration by fgsch@, deraadt@ and myself; tests by fgsch@, naddy@ and
myself; beer drinking by myself.
Please note that system upgrades with this new code will require a new
libc and ld.so to be build and installed before the propolice-enabled
compiler can be installed.
