* Sync up linux and svr compat elf fixup functions for exec(). TheseJohn Baldwin2003-03-211-10/+9
| | | | | | | | | | | | 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.

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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o Introduce private types for use in linux syscalls for two reasons: 1. establish type independence for ease in porting and, 2. provide a visual queue as to which syscalls have proper prototypes to further cleanup the i386/alpha split. Linuxulator types are prefixed by 'l_'. void and char have not been "virtualized". o Provide dummy functions for all syscalls and remove dummy functions or implementations of truely obsolete syscalls. o Sanitize the shm*, sem* and msg* syscalls. o Make a first attempt to implement the linux_sysctl syscall. At this time it only returns one MIB (KERN_VERSION), but most importantly, it tells us when we need to add additional sysctls :-) o Bump the kenel version up to 2.4.2 (this is not the same as the KERN_VERSION MIB, BTW). o Implement new syscalls, of which most are specific to i386. Our syscall table is now up to date with Linux 2.4.2. Some highlights: - Implement the 32-bit uid_t and gid_t bases syscalls. - Implement a couple of 64-bit file size/offset bases syscalls. o Fix or improve numerous syscalls and prototypes. o Reduce style(9) violations while I'm here. Especially indentation inconsistencies within the same file are addressed. Re-indenting did not obfuscate actual changes to the extend that it could not be combined. NOTE: I spend some time testing these changes and found that if there were regressions, they were not caused by these changes AFAICT. It was observed that installing a RH 7.1 runtime environment did make matters worse. Hangs and/or reboots have been observed with and without these changes, so when it failed to make life better in cases it doesn't look like it made it worse. Notes: svn path=/head/; revision=83221

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. establish type independence for ease in porting and, 2. provide a visual queue as to which syscalls have proper prototypes to further cleanup the i386/alpha split. Linuxulator types are prefixed by 'l_'. void and char have not been "virtualized". o Provide dummy functions for all unimplemented syscalls, except for the osf1 syscalls. This can only be done if the osfulator implements at least all syscalls used by the linuxulator. Remove dummy functions for syscalls that are now truely unimplemented. o Set the syscall namespace as follows: Mark a syscall as OSF1 if the Linux kernel has prefixed the syscall with 'osf_' and has provided special implementations for it. Otherwise mark the syscall as LINUX by default. Some of the LINUX syscalls remain marked as BSD or POSIX. o Rename syscalls so they match the names used in the Linux kernel. Also, provide more accurate prototypes. This generally improves cross-referencing and reduces head-scratching. o Fix the (g|s)etresuid syscalls. They mapped to (g|s)etresgid. o Sanitize the the shm*, sem* and msg* syscalls. Their prototypes were dictated by the way these syscalls were used in the i386 code. That has been fixed. NOTE: linux_semctl now passes it's 'arg' parameter by value and not by reference. o Fix prototype of linux_utime. It takes a struct timeval, not a struct utimbuf. o Fix the linux_sysfs syscall. It's index is not 255, but 254. o Implement the following syscalls: linux_sysctl o Add the following new syscalls: (g|s)etresgid linux_pivot_root (dummy) linux_mincore (dummy) linux_pciconfig_iobase (dummy) linux_getdents64 Notes: svn path=/head/; revision=83220

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