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.
|
| 1.35 |
| 19-Jan-2021 |
simonb | KNF consistency: No parentheses are needed around the return value.
|

pgoyette | branches: 1.34.4; 1.34.12;
Merge the [pgoyette-compat] branch
|
| 1.33 |
| 10-Dec-2012 |
chs | branches: 1.33.30; 1.33.36; 1.33.38;
fix these *stat routines: don't pass a kernel stack buffer
to a function that will try to copyout() to it.
just do both layers of compat translation here.
|
| 1.32 |
| 30-Jan-2009 |
njoly | branches: 1.32.14; 1.32.24;
Cleanup. Kill a few netbsd32_caddr_t in syscalls argument types.
|
| 1.31 |
| 29-May-2008 |
mrg | branches: 1.31.6; 1.31.12;
remove clause #3 from my license where there are no other
copyright holders involved.
|
| 1.30 |
| 20-Dec-2007 |
dsl | branches: 1.30.6; 1.30.8; 1.30.10; 1.30.12;
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.
|
| 1.29 |
| 08-Dec-2007 |
dsl | branches: 1.29.4;
ANSIfy most of the function definitions in sys/compat (but not ndis).
All by the magic of sed ...
|
| 1.28 |
| 04-Dec-2007 |
dsl | Remove all the __P
|
| 1.27 |
| 30-Apr-2007 |
dsl | branches: 1.27.6; 1.27.8; 1.27.14; 1.27.16;
Remove some unused calls to stackgap_init()
|
| 1.26 |
| 22-Apr-2007 |
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.
|
| 1.25 |
| 18-Mar-2007 |
dsl | Change all the NETBSD32PTR64(SCARG(uap, xxx))) to SCARG_P32(uap, xxx).
|
| 1.24 |
| 16-Mar-2007 |
dsl | remove all the double (and triple) casts used to convert 32bit userspace
pointers to and from 64bit kernel pointers. Instead use the defines
NETBSD32PTR64(p32) to read a 32bit pointer and (the new) NETBSD32PTR32(p32,p64)
to write a 32bit pointer throughout.
The 32bit pointer is now a struct to enforce the above.
amd64 (with linux emul) and sparc64 will both compile (when the arch stuff
goes in soon), and amd64 still runs some i386 binaries.
|
| 1.23 |
| 04-Mar-2007 |
christos | branches: 1.23.2; 1.23.4; 1.23.6;
fix fallout from caddr_t changes.
|
| 1.22 |
| 04-Mar-2007 |
christos | Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
|
| 1.21 |
| 09-Feb-2007 |
ad | branches: 1.21.2;
Merge newlock2 to head.
|
| 1.20 |
| 11-Dec-2005 |
christos | branches: 1.20.20;
merge ktrace-lwp.
|
| 1.19 |
| 13-Sep-2005 |
christos | make this compile again.
|
| 1.18 |
| 29-Jun-2003 |
fvdl | branches: 1.18.2; 1.18.18;
Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.
|
| 1.17 |
| 28-Jun-2003 |
darrenr | Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V
|
| 1.16 |
| 18-Jan-2003 |
thorpej | Merge the nathanw_sa branch.
|
| 1.15 |
| 23-Oct-2002 |
scw | In preparation for COMPAT_NETBSD32 on SH-5:
- The MD netbsd32_machdep.h header now defines the 32-bit pointer type
instead of using u_int32_t everywhere,
- The MD netbsd32_machdep.h header now defines a macro (at least on
current implementations) which converts a 32-bit pointer to its 64-bit
equivalent,
- Change the MI code to utilise the above two items in all the right places,
- Implement netbsd32___sigaction_sigtramp().
Tested on Sparc64 by Matt Green.
|
| 1.14 |
| 16-Mar-2002 |
christos | make the stackgap_{init,alloc} functions MP friendly (i.e. pass struct proc *
in, instead of using curproc). While there add an optional size argument to
stackgap_init.
|
| 1.13 |
| 13-Nov-2001 |
lukem | add RCSIDs (including regeneration of files as appropriate)

compat_12_netbsd32_{,fl}stat12() were not copyout()ing the converted result.

fvdl | Include opt_* files to make sure prototypes are included.
|
| 1.8 |
| 01-Dec-2000 |
jdolecek | prototype netbsd32_stat12_to_netbsd32()
|
| 1.7 |
| 01-Dec-2000 |
jdolecek | add e_path (emulation path) to struct emul, which replaces emulation-specific
*_emul_path variables
change macros CHECK_ALT_{CREAT|EXIST} to use that, 'root' doesn't need
to be passed explicitly any more and *_CHECK_ALT_{CREAT|EXIST} are removed
change explicit emul_find() calls in probe functions to get the emulation
path from the checked exec switch entry's emulation
remove no longer needed header files
add e_flags and e_syscall to struct emul; these are unsed and empty for now
|
| 1.6 |
| 11-Oct-1999 |
eeh | branches: 1.6.2;
Add netbsd32_compat_14.c
Rename everything from compat_netbsd32 -> netbsd32 so we don't have silly
names like compat_14_compat_netbsd32_sys_shmctl().
|
| 1.5 |

mrg | branches: 1.5.8;
SPARC32->NETBSD32
|

eeh | Overhaul. Now will run simple things like /bin/sh and /bin/echo.
|
| 1.2 |

|

darrenr | Apply the aborted ktrace-lwp changes to a specific branch. This is just for
others to review, I'm concerned that patch fuziness may have resulted in some
errant code being generated but I'll look at that later by comparing the diff
from the base to the branch with the file I attempt to apply to it. This will,
at the very least, put the changes in a better context for others to review
them and attempt to tinker with removing passing of 'struct lwp' through
the kernel.

| 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.
|
| 1.30.12.1 |
| 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.

the next higher version.
