martin | branches: 1.33.2; 1.33.6;
Remove clause 3 and 4 from TNF licenses

dsl | branches: 1.32.6; 1.32.8; 1.32.10;
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.

| 1.31 |
| 19-Oct-2007 |
njoly | branches: 1.31.4; 1.31.8;
Add compat_linux and exec_linux_elf lkm support for amd64:
- Add needed COMPAT_OSSAUDIO to GENERIC.
- Add missing includes needed by linux_syscallargs.h.
- Add lkm building.

christos | __unused removal on arguments; approved by core.
|
| 1.28 |
| 12-Oct-2006 |
christos | - sprinkle __unused on function decls.
- fix a couple of unused bugs
- no more -Wno-unused for i386
|

christos | branches: 1.27.20; 1.27.22;
merge ktrace-lwp.

manu | branches: 1.26.2;
First work on COMPAT_LINUX/amd64
Process startup and dynamiclinking work, but processes hang due to
Linux arch_prctl(2) not being really supported yet.
|
| 1.25 |
| 18-Jan-2003 |
thorpej | branches: 1.25.2;
Merge the nathanw_sa branch.
|
| 1.24 |
| 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.
|
| 1.23 |
| 31-Mar-2002 |
christos | branches: 1.23.2;
make signal array handling uniform, and put signal arrays in a separate
file. This is simular to errno array handling.
|
| 1.22 |
| 15-Feb-2002 |
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.

|

| 09-Aug-2000 |
tv | branches: 1.20.2; 1.20.4;
Pretend to do something useful (just fill in oldsigaction with SIG_IGN and
zeroes) if the mapped signal number comes up zero. Previously, sigaction1()
would return an error, confusing some linux apps trying to set handlers for
"all" signals.

erh | branches: 1.17.12; 1.17.18;
This is used on the alpha. It is called osf_sigaction under linux because of the format of the sigaction structure but it acts the same.

| 11-Sep-1998 |
mycroft | Substantial signal handling changes:
* Increase the size of sigset_t to accomodate 128 signals -- adding new
versions of sys_setprocmask(), sys_sigaction(), sys_sigpending() and
sys_sigsuspend() to handle the changed arguments.
* Abstract the guts of sys_sigaltstack(), sys_setprocmask(), sys_sigaction(),
sys_sigpending() and sys_sigsuspend() into separate functions, and call them
from all the emulations rather than hard-coding everything. (Avoids uses
the stackgap crap for these system calls.)
* Add a new flag (p_checksig) to indicate that a process may have signals
pending and userret() needs to do the full (slow) check.
* Eliminate SAS_ALTSTACK; it's exactly the inverse of SS_DISABLE.
* Correct emulation bugs with restoring SS_ONSTACK.
* Make the signal mask in the sigcontext always use the emulated mask format.
* Store signals internally in sigaction structures, rather than maintaining a
bunch of little sigsets for each SA_* bit.
* Keep track of where we put the signal trampoline, rather than figuring it out
in *_sendsig().
* Issue a warning when a non-emulated sigaction bit is observed.
* Add missing emulated signals, and a native SIGPWR (currently not used).
* Implement the `not reset when caught' semantics for relevant signals.
Note: Only code touched by the i386 port has been modified. Other ports and
emulations need to be updated.

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, 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.
|
| 1.33.2.1 |
| 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.
