Do a pass over all modules in the kernel and make them return EOPNOTSUPP

for unknown events. A number of modules return EINVAL in this instance, and I have left those alone for now and instead taught MOD_QUIESCE to accept this as "didn't do anything".

Add an additional field to the elf brandinfo structure to support

quicker exec-time replacement of the elf interpreter on an emulation environment where an entire /compat/* tree isn't really warranted.

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.

Rename P_THREADED to P_SA. P_SA means a process is using scheduler

Sync up linux and svr compat elf fixup functions for exec(). These

2003-03-21T19:49:34Z

functions are now all basically identical except that alpha linux uses Elf64 arguments and svr4 and i386 linux use Elf32. The fixups include changing the first argument to be a register_t ** to match the prototype for fixup functions, asserting that the process in the image_params struct is always curproc and removing unnecessary locking to read credentials as a result, and a few style fixes.

Added fields for VM_MIN_ADDRESS, PS_STRINGS and stack protections to

sysentvec. Initialized all fields of all sysentvecs, which will allow them to be used instead of constants in more places. Provided stack fixup routines for emulations that previously used the default.

Infrastructure tweaks to allow having both an Elf32 and an Elf64 executable

handler in the kernel at the same time. Also, allow for the exec_new_vmspace() code to build a different sized vmspace depending on the executable environment. This is a big help for execing i386 binaries on ia64. The ELF exec code grows the ability to map partial pages when there is a page size difference, eg: emulating 4K pages on 8K or 16K hardware pages. Flesh out the i386 emulation support for ia64. At this point, the only binary that I know of that fails is cvsup, because the cvsup runtime tries to execute code in pages not marked executable. Obtained from: dfr (mostly, many tweaks from me).
