* 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.

* Enable vmspace sharing on SMP. Major changes are,Luoqi Chen1999-04-281-4/+6
| | | | | | | | | | | | | | | | | | | | - %fs register is added to trapframe and saved/restored upon kernel entry/exit. - Per-cpu pages are no longer mapped at the same virtual address. - Each cpu now has a separate gdt selector table. A new segment selector is added to point to per-cpu pages, per-cpu global variables are now accessed through this new selector (%fs). The selectors in gdt table are rearranged for cache line optimization. - fask_vfork is now on as default for both UP and SMP. - Some aio code cleanup.

| | | | | | | | | | | | | | | | | | | | Compile and link a new kernel, that will give native ELF support, and provide the hooks for other ELF interpreters as well. To make native ELF binaries use John Polstras elf-kit-1.0.1.. For the time being also use his ld-elf.so.1 and put it in /usr/libexec. The Linux emulator has been enhanced to also run ELF binaries, it is however in its very first incarnation. Just get some Linux ELF libs (Slackware-3.0) and put them in the prober place (/compat/linux/...). I've ben able to run all the Slackware-3.0 binaries I've tried so far. (No it won't run quake yet :) Notes: svn path=/head/; revision=14456
* Mega-commit for Linux emulator update.. This has been stress tested underPeter Wemm1996-03-021-0/+358
netscape-2.0 for Linux running all the Java stuff. The scrollbars are now working, at least on my machine. (whew! :-) I'm uncomfortable with the size of this commit, but it's too inter-dependant to easily seperate out. The main changes: COMPAT_LINUX is *GONE*. Most of the code has been moved out of the i386 machine dependent section into the linux emulator itself. The int 0x80 syscall code was almost identical to the lcall 7,0 code and a minor tweak allows them to both be used with the same C code. All kernels can now just modload the lkm and it'll DTRT without having to rebuild the kernel first. Like IBCS2, you can statically compile it in with "options LINUX". A pile of new syscalls implemented, including getdents(), llseek(), readv(), writev(), msync(), personality(). The Linux-ELF libraries want to use some of these. linux_select() now obeys Linux semantics, ie: returns the time remaining of the timeout value rather than leaving it the original value. Quite a few bugs removed, including incorrect arguments being used in syscalls.. eg: mixups between passing the sigset as an int, vs passing it as a pointer and doing a copyin(), missing return values, unhandled cases, SIOC* ioctls, etc. The build for the code has changed. i386/conf/files now knows how to build linux_genassym and generate linux_assym.h on the fly. Supporting changes elsewhere in the kernel: The user-mode signal trampoline has moved from the U area to immediately below the top of the stack (below PS_STRINGS). This allows the different binary emulations to have their own signal trampoline code (which gets rid of the hardwired syscall 103 (sigreturn on BSD, syslog on Linux)) and so that the emulator can provide the exact "struct sigcontext *" argument to the program's signal handlers. The sigstack's "ss_flags" now uses SS_DISABLE and SS_ONSTACK flags, which have the same values as the re-used SA_DISABLE and SA_ONSTACK which are intended for sigaction only. This enables the support of a SA_RESETHAND flag to sigaction to implement the gross SYSV and Linux SA_ONESHOT signal semantics where the signal handler is reset when it's triggered. makesyscalls.sh no longer appends the struct sysentvec on the end of the generated init_sysent.c code. It's a lot saner to have it in a seperate file rather than trying to update the structure inside the awk script. :-) At exec time, the dozen bytes or so of signal trampoline code are copied to the top of the user's stack, rather than obtaining the trampoline code the old way by getting a clone of the parent's user area. This allows Linux and native binaries to freely exec each other without getting trampolines mixed up. Notes: svn path=/head/; revision=14331
