Add sysentvec->sv_fixlimits() hook so that we can catch cases on 64 bit

2003-09-25T01:10:26Z

systems where the data/stack/etc limits are too big for a 32 bit process. Move the 5 or so identical instances of ELF_RTLD_ADDR() into imgact_elf.c. Supply an ia32_fixlimits function. Export the clip/default values to sysctl under the compat.ia32 heirarchy. Have mmap(0, ...) respect the current p->p_limits[RLIMIT_DATA].rlim_max value rather than the sysctl tweakable variable. This allows mmap to place mappings at sensible locations when limits have been reduced. Have the imgact_elf.c ld-elf.so.1 placement algorithm use the same method as mmap(0, ...) now does. Note that we cannot remove all references to the sysctl tweakable maxdsiz etc variables because /etc/login.conf specifies a datasize of 'unlimited'. And that causes exec etc to fail since it can no longer find space to mmap things.

Style sync.

- Fix visibilty test for LONG_BIT and WORD_BIT. `#if defined(__FOO_VISIBLE)' is alays wrong because __FOO_VISIBLE is always defined (to 0 for invisibility). sys//include/limits.h sys//include/_limits.h: - Style fixes. Submitted by: bde Reviewed by: bsdmike Approved by: re (scottl)

Style fixes.

2003-05-04T22:13:04Z

Remove DBL_DIG, DBL_MIN, DBL_MAX and their FLT_ counterparts, they were marked for deprecation ever since SUSv1 at least. Only define ULLONG_MIN/MAX and LLONG_MAX if long long type is supported. Restore a lost comment in MI _limits.h file and remove it from sys/limits.h where it does not belong.

Deprecate machine/limits.h in favor of new sys/limits.h.

- Add vm_paddr_t, a physical address type. This is required for systems

2003-03-25T00:07:06Z

where physical addresses larger than virtual addresses, such as i386s with PAE. - Use this to represent physical addresses in the MI vm system and in the i386 pmap code. This also changes the paddr parameter to d_mmap_t. - Fix printf formats to handle physical addresses >4G in the i386 memory detection code, and due to kvtop returning vm_paddr_t instead of u_long. Note that this is a name change only; vm_paddr_t is still the same as vm_offset_t on all currently supported platforms.

Initiate deorbit burn for the i386-only a.out related support. Moves are

2002-09-17T01:49:00Z

under way to move the remnants of the a.out toolchain to ports. As the comment in src/Makefile said, this stuff is deprecated and one should not expect this to remain beyond 4.0-REL. It has already lasted WAY beyond that. Notable exceptions: gcc - I have not touched the a.out generation stuff there. ldd/ldconfig - still have some code to interface with a.out rtld. old as/ld/etc - I have not removed these yet, pending their move to ports. some includes - necessary for ldd/ldconfig for now. Tested on: i386 (extensively), alpha
