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

Without this patch, an SA_SIGINFO style handler can be installed by a linux app, but if the handler accesses its sip argument, it will get a garbage pointer and likely segfault. We currently supply a valid pointer, but its contents are mainly garbage. Filling this in properly is future work. This is the second of 3 commits that will get IBM's JDK 1.3 working with FreeBSD ...

* sigset_t change (part 4 of 5)marcel1999-09-291-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ----------------------------- 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.

* Major rewrite.marcel1999-08-151-239/+50
| | | | | | | | | | | | | | | | | The first reason for this rewrite is KNF conformance. The second reason is to avoid redundancy. Each function printed the same string, with only the syscall name being different. The actual printing is now performed by a single function, which gets the syscall name as an argument. The third reason is that of convenience. It's now very easy to add a new dummy implementation. Just add ``DUMMY(foo);'' to the file. It's also a lot easier now to see if a syscall has a dummy implementation or not. The dummies are ordered on syscall number. Please maintain this when adding new dummies (there're 32 candidates at the time of writing :-) Reviewed by: bde

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.

* First incarnation of our Linux emulator or rather compatibility code.sos1995-06-251-0/+316
This first shot only incorporaties so much functionality that DOOM can run (the X version), signal handling is VERY weak, so is many other things. But it meets my milestone number one (you guessed it - running DOOM). Uses /compat/linux as prefix for loading shared libs, so it won't conflict with our own libs. Kernel must be compiled with "options COMPAT_LINUX" for this to work.
