riastradh | sys/compat: Memset zero before copyout.
Just in case of uninitialized padding which would lead to kernel stack disclosure. If the compiler can prove the memset redundant then it can optimize it away; otherwise better safe than sorry.

chs | branches: 1.42.52; 1.42.64; many changes for COMPAT_LINUX: - update the linux syscall table for each platform. - support new-style (NPTL) linux pthreads on all platforms. clone() with CLONE_THREAD uses 1 process with many LWPs instead of separate processes. - move the contents of sys__lwp_setprivate() into a new lwp_setprivate() and use that everywhere. - update linux_release[] and linux32_release[] to "2.6.18". - adjust placement of emul fork/exec/exit hooks as needed and adjust other emul code to match. - convert all struct emul definitions to use named initializers. - change the pid allocator to allow multiple pids to refer to the same proc. - remove a few fields from struct proc that are no longer needed. - disable the non-functional "vdso" code in linux32/amd64, glibc works fine without it. - fix a race in the futex code where we could miss a wakeup after a requeue operation. - redo futex locking to be a little more efficient.

ad | branches: 1.37.2; Merge proc::p_mutex and proc::p_smutex into a single adaptive mutex, since we no longer need to guard against access from hardware interrupt handlers.
Additionally, if cloning a process with CLONE_SIGHAND, arrange to have the child process share the parent's lock so that signal state may be kept in sync. Partially addresses PR kern/37437.

dsl | branches: 1.36.6; 1.36.8; Convert all the system call entry points from: int foo(struct lwp *l, void *v, register_t *retval) to: int foo(struct lwp *l, const struct foo_args *uap, register_t *retval) Fixup compat code to not write into 'uap' and (in some cases) to actually pass a correctly formatted 'uap' structure with the right name to the next routine. A few 'compat' routines that just call standard ones have been deleted. All the 'compat' code compiles (along with the kernels required to test build it). 98% done by automated scripts.

fvdl | branches: 1.23.2; Define linux_usertrap function, and set it in struct emul. For all but amd64, it just returns 0, doing nothing.
For amd64, it implements vsyscalls through cheating: if the faulting address is in the vsyscall area (which is statically known on Linux/amd64), and the intruction pointer is too, it must have been a vsyscall. In that case, retrieve the return address from the user stack, fix up %rip and %rsp, and just execute the normal system call. It will return as if the vsyscall has been executed.

|
1.14 |
| 04-Jul-2002 |
thorpej | Add kernel support for having userland provide the signal trampoline:
* struct sigacts gets a new sigact_sigdesc structure, which has the sigaction and the trampoline/version. Version 0 means "legacy kernel provided trampoline". Other versions are coordinated with machine- dependent code in libc. * sigaction1() grows two more arguments -- the trampoline pointer and the trampoline version. * A new __sigaction_sigtramp() system call is provided to register a trampoline along with a signal handler. * The handler is no longer passed to sensig() functions. Instead, sendsig() looks up the handler by peeking in the sigacts for the process getting the signal (since it has to look in there for the trampoline anyway). * Native sendsig() functions now select the appropriate trampoline and its arguments based on the trampoline version in the sigacts.
Changes to libc to use the new facility will be checked in later. Kernel version not bumped; we will ride the 1.6C bump made recently.

christos | - add a real linux_sys___sysctl because the mib numbers are different. implement only the kernel version getting entries. - make the signal conversion functions consistent; dest is arg 1. - make linux_fakedev deal with block and char devices differently. - add linux_sys_ugetrlimit, and flesh out the regular get/setrlimit so that they work properly. - add linux_mmap2 [untested]. - bump kernel to 2.4.18, and make the date be valentine's day :-) - linux_sys_*stat64 family was totally busted. Fix it.
tested only on i386.
Status: gdb, telnet, work jdk-1.4.0 extractor works, jdk still coredumps.

nathanw | Curproc->curlwp renaming.
Change uses of "curproc->l_proc" back to "curproc", which is more like the original use. Bare uses of "curproc" are now "curlwp".
"curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL) so that it is always safe to reference curproc (*de*referencing curproc is another story, but that's always been true).

Follow the merge of pmap.c on i386 and amd64 and move pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup code to restore CR4 before jumping back into kernel space as the large page option might cover that.

wrstuden | Per discussion with ad at n dot o, revert signal mask handling changes.
The l_sigstk changes are most likely totally un-needed as SA will never use a signal stack - we send an upcall (or will as other diffs are brought in).
The l_sigmask changes were too controvertial. In all honesty, I think it's probably best to revert them. The main reason they were there is the fact that in an SA process, we don't mask signals per kernel thread, we mask them per user thread. In the kernel, we want them all to get turned into upcalls. Thus the normal state of l_sigmask in an SA process is for it to always be empty.
While we are in the process of delivering a signal, we want to temporarily mask a signal (so we don't recursively exhaust our upcall stacks). However signal delivery is rare (important, but rare), and delivering back-to-back signals is even rarer. So rather than cause every user of a signal mask to be prepared for this very rare case, we will just add a second check later in the signal delivery code. Said change is not in this diff.
This also un-compensates all of our compatability code for dealing with SA. SA is a NetBSD-specific thing, so there's no need for Irix, Linux, Solaris, SVR4 and so on to cope with it.
As previously, everything other than kern_sa.c compiles in i386 GENERIC as of this checkin. I will switch to ALL soon for compile testing.
|
1.38.2.2 |
| 14-May-2008 |
wrstuden | Per discussion with ad, remove most of the #include <sys/sa.h> lines as they were including sa.h just for the type(s) needed for syscallargs.h.
Instead, create a new file, sys/satypes.h, which contains just the types needed for syscallargs.h. Yes, there's only one now, but that may change and it's probably more likely to change if it'd be difficult to handle. :-)
Per discussion with matt at n dot o, add an include of satypes.h to sigtypes.h. Upcall handlers are kinda signal handlers, and signalling is the header file that's already included for syscallargs.h that closest matches SA.
This shaves about 3000 lines off of the diff of the branch relative to the base. That also represents about 18% of the total before this checkin.
I think this reduction is very good thing.
|
1.38.2.1 |
| 10-May-2008 |
wrstuden | Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting.
Also, kern_sa.c has received partial cleanup. There's still more to do, though.
