jdolecek | add dummy implementation of linux fallocate() which just returns EOPNOTSUPP;
this is needed so that glibc falls back to emulation and apps behaving
properly, since EOPNOTSUPP is a documented and expected return code, but
ENOSYS is not
right now there are no filesystems in NetBSD tree supporting the fallocate
VOP, so no point trying to map this to a native call
supposed to help with problem reported in

kamil | Avoid signed integer overflow when convering linux timeval to timespec
Linux accepts garbage as timeout and attempts to set it to something
meaningful. Instead of checking for valid ranges of usec, just convert
the type safely, regardless of what is inside it.

kamil | branches: 1.40.4;
Refactor pipe1() and correct a bug in sys_pipe2() (SYS_pipe2)
sys_pipe2() returns two integers (values), the 2nd one is a copy of the 2nd
file descriptor that lands in fildes[2]. This is a side effect of reusing
the code for sys_pipe() (SYS_pipe) and not cleaning it up.
The first returned value is (on success) 0.
Introduced a small refactoring in pipe1() that it does not operate over
retval[], but on an array int[2]. A user sets retval[] for pipe() when
desired and needed.
This refactoring touches compat code: netbsd32, linux, linux32.
Before the changes on NetBSD/amd64:
$ ktruss -i ./a.out
[...]
15131 1 a.out pipe2(0x7f7fff2e62b8, 0) = 0, 4
[...]
After the changes:
$ ktruss -i ./a.out
[...]
782 1 a.out pipe2(0x7f7fff97e850, 0) = 0
[...]
There should not be a visible change for current users.

- splits code out where necessary to be modular
- adds module glue for each of the components
- adds/replaces hooks for things that can be installed at runtime

Compat linux/linux32 nice(2) fix. The syscall argument is an increment
to be added to the current nice value, not an absolute value to be
set.

njoly | compat linux (and linux32) uid16 functions cleanup and fixes.
- Move uid16 functions to their own file linux_uid16.c, included by
needed archs (arm, i386 and m68k).
- Add new MI types linux_{u,g}id16_t.
- Add macros to handle linux_uid16_t and uid_t conversions.
- Add linux_sys_getres{uid,gid}16 syscalls, to fix an overflow with
bad sizes given to copyout when linux_sys_getres{uid,gid} are used.
- Update arm syscall table to use more uid16 functions.
|
| 1.18 |
| 21-Dec-2007 |
njoly | - Fix setfsuid to return uid on success.
- Replace getfsuid, which never existed on Linux, by correct setfsgid
syscall.
ok by christos and dsl.

dsl | 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.

compat linux32 syscalls cleanup.
With stackgap and CHECK_ALT_xxx removal, some linux32 and netbsd32
syscalls are now identical.
To avoid code duplication, remove the linux32 definition and use the
netbsd32 one (no functional change).

njoly | Add missing chown's syscalls family members.
This makes chown(1)/chgrp(1) works under compat linux32.

Remove a spare 'timeval' structure - makes this version of this function
match some of the other copies lurking in the world of compat.

dsl | Change the way that emulations locate files within the emulation root to
avoid having to allocate space in the 'stackgap'
- which is very LWP unfriendly.
The additional code for non-emulation namei() is trivial, the reduction for
the emulations is massive.
The vnode for a processes emulation root is saved in the cwdi structure
during process exec.
If the emulation root the TRYEMULROOT flag are set, namei() will do an initial
search for absolute pathnames in the emulation root, if that fails it will
retry from the normal root.
".." at the emulation root will always go to the real root, even in the middle
of paths and when expanding symlinks.
Absolute symlinks found using absolute paths in the emulation root will be
relative to the emulation root (so /usr/lib/xxx.so -> /lib/xxx.so links
inside the emulation root don't need changing).
If the root of the emulation would be returned (for an emulation lookup), then
the real root is returned instead (matching the behaviour of emul_lookup,
but being a cheap comparison here) so that programs that scan "../.."
looking for the root dircetory don't loop forever.
The target for symbolic links is no longer mangled (it used to get the
CHECK_ALT_xxx() treatment, so could get /emul/xxx prepended).
CHECK_ALT_xxx() are no more. Most of the change is deleting them, and adding
TRYEMULROOT to the flags to NDINIT().
A lot of the emulation system call stubs could now be deleted.

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.
|
| 1.22.6.1 |
| 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.
