* Make SysV-style shared memory and semaphore limits sysctl'able.millert2002-12-171-1/+87
| | | | | | | | | | | | 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.
* Casting to unsigned int in isfoo() causes problems on alpha andmillert2002-12-151-12/+12
| | | | | | | 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.

* Instead of doing "if (c == EOF) return 0;" use the hook ('?') operatormillert2002-12-141-35/+13
| | | | | instead to make these one-liners. Works around a compiler bug on vax that affects both the libc and inline versions identically.

* Convert ctype.h macros into inline functions. This fixes the issues wemillert2002-12-112-4/+6
| | | | | | currently have with the macro versions and makes the ctype.h versions 100% identical to what is in libc. Discussed with pjanzen@ and OK'd by deraadt@.
* Make x_handy in XDR u_int, not int since there are places in themillert2002-12-111-9/+15
| | | | | | | | 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). deraadt@ OK

* BSD getopt() supports '-' in the optstring so we should too.millert2002-12-081-8/+15

* For getopt_long_only() we *do* want to match single-character optionsmillert2002-12-071-41/+36
| | | | | as shortcuts for long ones, but only if this would not conflict with a short option in optstring. Now binutils gas works.
* In srandomdev(), if we can't access /dev/arandom, use the sysctl() instead.millert2002-12-061-10/+27
| | | | | 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.
* Fix two compatibility issues with our getopt_long_only() vs. the GNU version:millert2002-12-061-28/+61
| | | | | | | | | | | | | | 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()
* Correctly handle -Wlong_arg (no space between -W and long_arg) when "W;"millert2002-12-051-6/+8
| | | | is in optstring.
* Reorganize this so that getopt_only_only() works correctly.millert2002-12-051-221/+208
| | | | | | | | 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.

| | | | | | | | | | | | | | | 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.
