* Add sysentvec->sv_fixlimits() hook so that we can catch cases on 64 bitPeter Wemm2003-09-251-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=120422

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

* Infrastructure tweaks to allow having both an Elf32 and an Elf64 executablePeter Wemm2002-07-201-4/+6
| | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace the a.out emulation of 'struct linker_set' with something a little more flexible. <sys/linker_set.h> now provides macros for accessing elements and completely hides the implementation. The linker_set.h macros have been on the back burner in various forms since 1998 and has ideas and code from Mike Smith (SET_FOREACH()), John Polstra (ELF clue) and myself (cleaned up API and the conversion of the rest of the kernel to use it). The macros declare a strongly typed set. They return elements with the type that you declare the set with, rather than a generic void *. For ELF, we use the magic ld symbols (__start_<setname> and __stop_<setname>). Thanks to Richard Henderson <rth@redhat.com> for the trick about how to force ld to provide them for kld's. For a.out, we use the old linker_set struct. NOTE: the item lists are no longer null terminated. This is why the code impact is high in certain areas. The runtime linker has a new method to find the linker set boundaries depending on which backend format is in use. linker sets are still module/kld unfriendly and should never be used for anything that may be modular one day.

* Change our ELF binary branding to something more acceptable to the BinutilsDavid E. O'Brien2000-04-181-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | maintainers. After we established our branding method of writing upto 8 characters of the OS name into the ELF header in the padding; the Binutils maintainers and/or SCO (as USL) decided that instead the ELF header should grow two new fields -- EI_OSABI and EI_ABIVERSION. Each of these are an 8-bit unsigned integer. SCO has assigned official values for the EI_OSABI field. In addition to this, the Binutils maintainers and NetBSD decided that a better ELF branding method was to include ABI information in a ".note" ELF section. With this set of changes, we will now create ELF binaries branded using both "official" methods. Due to the complexity of adding a section to a binary, binaries branded with ``brandelf'' will only brand using the EI_OSABI method. Also due to the complexity of pulling a section out of an ELF file vs. poking around in the ELF header, our image activator only looks at the EI_OSABI header field. Note that a new kernel can still properly load old binaries except for Linux static binaries branded in our old method. * * For a short period of time, ``ld'' will also brand ELF binaries * using our old method. This is so people can still use kernel.old * with a new world. This support will be removed before 5.0-RELEASE, * and may not last anywhere upto the actual release. My expiration * time for this is about 6mo. * Notes: svn path=/head/; revision=59342

| | | | | | | | | | | to `register_t *'. This fixes bugs like misplacement of argc and argv on the user stack on i386's with 64-bit longs. We still use longs to represent "words" like argc and argv, and assume that they are on the stack (and that there is stack). The suword() and fuword() families should also use register_t.

* Implement pluggable ioctl handlers.Marcel Moolenaar1999-12-041-7/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | Other modules can register and unregister ioctl handlers to extend the ioctls known by the Linuxulator. A recent application is the vmware port. The Linuxulator itself uses the new interface to register its handlers as well. Handlers for the following types of ioctls have been defined: cdrom console (=keyboard and VT handling) socket sound termio All ioctl related defines and declarations have been moved to a new file (linux_ioctl.h), except for the pluggable ioctl handler interface definition. While there, cleanup linux.h some more. linux.h and linux_ioctl.[ch] have been made to conform to style(9) as much as possible. Inspired and reviewed by: Vladimir N.

* sigset_t change (part 4 of 5)Marcel Moolenaar1999-09-291-46/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ----------------------------- The compatibility code and/or emulators have been updated: iBCS2 now mostly uses the older syscalls. SVR4 now properly handles all signals. This has been achieved by using the new sigset_t throughout the emulator. The Linuxulator has been severely updated. Internally the new Linux sigset_t is made the default. These are then mapped to and from the new FreeBSD sigset_t. Also, rt_sigsuspend has been implemented in the Linuxulator. Implementing this syscall basicly caused all this sigset_t changing in the first place and the syscall has been used throughout the change as a means for testing. It basicly is too much work to undo the implementation so that it can later be added again. A special note on the use of sv_sigtbl and sv_sigsize in struct sysentvec: Every signal larger than sv_sigsize is not translated and is passed on to the signal handler unmodified. Signals in the range 1 upto and including sv_sigsize are translated. The rationale is that only the system defined signals need to be translated. The emulators also have been updated so that the translation tables are only indexed for valid (system defined) signals. This change also fixes the translation bug already in the SVR4 emulator.
