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.

Properly mark netbsd32_compat_43 syscalls that are directly implemented
by calling their compat_43 equivalents. With these changes, and with
built-in versions of COMPAT_NETBSD32, COMPAT_NOMID, and COMPAT_09, I can
now run a netbsd-0.9 statically linked i386 (32-bit) version of /bin/ls
on a 9.99.x amd64 host!
Addresses PR kern/55047 but more changes coming to handle non-built-in
modules.

| 01-Jan-2020 |
maxv | Fix sizeof mismatch in copyin. This leads to a user-triggerable stack
overflow. On my test build at least, by luck, the compiler orders the
variables in a way that the overflow hits only local structures which
haven't yet been initialized and used, so the overflow is harmless.
Very easily seeable with kASan - just invoke the syscall from a 32bit
binary.

Fix COMPAT_NETBSD32 cmsg handling:
1. alignment was wrong for > 1 message
2. macros were doing incorrect pointer comparisons, fortunately ending
the iteration early after the fists cmsg instead of crashing.
3. don't output 32 bit ktrace records for cmsg. 32 bit programs running
under emulation on 64 bit systems should produce 64 bit ktrace records
so that the native ktrace can handle the records; remove extra arguments
that are now not needed (the 32 bit msghdr).
4. output the correct type for cmsg trace records.
5. output all the cmsg records in traces instead of just the first one.
Welcome to 8.99.15 because of the argument removal.
XXX: Really all the code should be changed to use the CMSG_{FIRST,NXT}HDR
macros...

christos | PR/53103: Timo Buhrmester: linux emulation of sendto(2) broken
The sockargs refactoring broke it, because sockargs only works with a user

coming from. Welcome to 8.99.14.

Make the ktrace record written by do_sys_sendmsg/do_sys_recvmsg overridable
by the caller. Use this in compat_netbsd32 to log the 32bit version, so
the 32bit userland kdump is happy.

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).

dsl | sendmsg() shouldn't modify the 'msg' parameter, and recvmsg() doesn't have

|
| 1.41 |
| 30-Apr-2007 |
dsl | Rework compat stat() and statvfs() code so that it no longer uses the stackgap.
|
| 1.40 |
| 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.
|
| 1.39 |
| 18-Mar-2007 |
dsl | Change all the NETBSD32PTR64(SCARG(uap, xxx))) to SCARG_P32(uap, xxx).
|
| 1.38 |
| 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.

Dynamic sysctl.
Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(),
vfs_sysctl(), etc, routines, along with sysctl_int() et al. Now all
nodes are registered with the tree, and nodes can be added (or
removed) easily, and I/O to and from the tree is handled generically.
Since the nodes are registered with the tree, the mapping from name to
number (and back again) can now be discovered, instead of having to be
hard coded. Adding new nodes to the tree is likewise much simpler --
the new infrastructure handles almost all the work for simple types,
and just about anything else can be done with a small helper function.
All existing nodes are where they were before (numerically speaking),
so all existing consumers of sysctl information should notice no
difference.
PS - I'm sorry, but there's a distinct lack of documentation at the
moment. I'm working on sysctl(3/8/9) right now, and I promise to
watch out for buses.

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

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.

errant code being generated but I'll look at that later by comparing the diff

at the very least, put the changes in a better context for others to review

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.

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.

Properly mark netbsd32_compat_43 syscalls that are directly implemented
by calling their compat_43 equivalents. With these changes, and with
built-in versions of COMPAT_NETBSD32, COMPAT_NOMID, and COMPAT_09, I can
now run a netbsd-0.9 statically linked i386 (32-bit) version of /bin/ls
on a 9.99.x amd64 host!
Addresses PR kern/55047 but more changes coming to handle non-built-in

Fix sizeof mismatch in copyin. This leads to a user-triggerable stack
overflow. On my test build at least, by luck, the compiler orders the
variables in a way that the overflow hits only local structures which
haven't yet been initialized and used, so the overflow is harmless.
Very easily seeable with kASan - just invoke the syscall from a 32bit
binary.
Fix three stack info leaks, found by kMSan when just invoking all syscalls
with a zero page as argument.
MSan: Uninitialized Stack Memory In copyout() At Offset 0, Variable 'sb32' From compat_20_netbsd32_getfsstat()
MSan: Uninitialized Stack Memory In copyout() At Offset 12, Variable 'oss' From compat_43_sys_sigstack()

Fix info leaks.
Fix stupid bugs in linux_sys_shmctl(): the index could be out of bound
(page fault) and there was no proper locking.
Maybe we should just remove LINUX_SHM_STAT, like compat_linux32.
Remove printf.
When dealing with an unknown value, set -1, to prevent (harmless)
uninitialized accesses later.
Add a default case, don't call sys_ioctl() with an uninitialized 'com'
argument.
Fix error handling, returns an errno, not -1.
Put the printf under DEBUG_LINUX.
Hum, don't forget the 'pid' argument, otherwise we're not gonna go very
far.
Don't read data from userland directly. This simply does not work on any
recent x86 CPU (thanks to SMAP) and all architectures that forbid direct
access to userland from the kernel. But I guess no one noticed because no
one ever uses compat_linux, right?
Hum, don't pass an mbuf to realloc(). Inspired from copyin32_msg_control().
Fix memory leak.
I don't see the point in having this useless printf, but add a '\n' to it,
so that it at least displays useless stuff correctly.
Hum, remove incorrect assignment. Userland could have passed a smaller
namelen, and the uninitialized bytes from sb_data were being used later in
the network stack.
