mlelstv | Crude patch to allow building and loading of compat_16 and compat_netbsd32_16 code
on aarch64.

COMPAT_NETBSD32 is all about running the 32-bit flavor of native
binaries on a 64-bit platform[*], as such:
- Make the logic about which "sendsig" flavor to call MI (as it is in the
native 64-bit environment) and follow the same rules as the native 32-bit
environment.
- Make COMPAT_NETBSD32 x COMPAT_16 work the same as it would in the
native 32-bit environment by providing a netbsd32_sendsig_sigcontext_16_hook,
rather than overriding the entire sendsig logic with a netbsd32_sendsig_hook.
- In netbsd32___sigaction_sigtramp(), make sure the compat_netbsd32_16
module is loaded if the trampoline version specifies a sigcontext style
handler, otherwise return EINVAL so that libc can try again with siginfo
style.
[*] ...except for arm32, which uses it to mean "run 32-bit OABI binaries
from the 32-bit EABI environment". Doing it this way was arguably a mistake,
but we are stuck with it for now, so support it by providing a machine-
dependent override for netbsd32_sendsig() that also disables the corresponding
logic in netbsd32___sigaction_sigtramp().
Fixes PR kern/56487.

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.

rin | When converting siginfo, examine si_code at the beginning,

- If it is SI_NOINFO, there's no additional information.
- If it is non-positive, i.e., codes described in siginfo(2),
we need to fill in _rt.

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.

drochner | -SUS says that a successful call to setcontext(2) does not return. This
implies that _UC_CPU must be set in the context passed. Check for this
and return EINVAL if not; this gives a cheap test for corrupted
ucontexts eg on a signal handler stack which would go unnoticed otherwise.
-Don't ckeck for NULL ucontext pointers explicitely. This is an error,
except in the swapcontext() case where it can be easily caught in
userland.

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.
|
| 1.3 |
| 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.

are sa-specific versions of getucontext{,32}(). The main difference

signal mask, both to avoid needing p_lock and because the process
signal mask is almost always 0 for SA.

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.
|
| 1.29.4.1 |
| 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.

Make {s,g}et{db,fp,}regs work again for PK_32 processes
XXX: pullup-8
add disgusting magic to handle compat_netbsd32 as a module.
use process_*reg32 instead of struct *reg32.
Remove the filesystem tracing feature
This is a legacy interface from 4.4BSD, and it was
introduced to overcome shortcomings of ptrace(2) at that time, which are
no longer relevant (performance). Today /proc/#/ctl offers a narrow
subset of ptrace(2) commands and is not applicable for modern
applications use beyond simplistic tracing scenarios.
This removal will simplify kernel internals. Users will still be able to
use all the other /proc files.
This change won't affect other procfs files neither Linux compat
features within mount_procfs(8). /proc/#/ctl isn't available on Linux.
Remove:
- /proc/#/ctl from mount_procfs(8)
- P_FSTRACE note from the documentation of ps(1)
- /proc/#/ctl and filesystem tracing documentation from mount_procfs(8)
- KAUTH_REQ_PROCESS_PROCFS_CTL documentation from kauth(9)
- source code file miscfs/procfs/procfs_ctl.c
- PFSctl and procfs_doctl() from sys/miscfs/procfs/procfs.h
- KAUTH_REQ_PROCESS_PROCFS_CTL from sys/sys/kauth.h
- PSL_FSTRACE (0x00010000) from sys/sys/proc.h
- P_FSTRACE (0x00010000) from sys/sys/sysctl.h
Reduce code complexity after removal of this functionality.
Update TODO.ptrace accordingly: remove two entries about /proc tracing.
Do not keep legacy notes as comments in the headers about removed
PSL_FSTRACE / P_FSTRACE, as this interface had little number of users
(close or equal to zero).
Proposed on tech-kern@.
All filesystem tracing utility users are encouraged to switch to ptrace(2).

untangle the mess:
- factor out common code
- break each ptrace subcall to its own sub-function
.. more to come ...
- reduce ifdef ugliness by moving it up top.
- factor out PT_IO and make PT_{READ,WRITE}_{I,D} use it
- factor out PT_DUMPCORE
- factor out sendsig code
.. more to come ...
handle siginfo requests for ptrace32
ptrace: Partially undo PT_{READ,WRITE}_{I,D} and unbreak these commands
The refactored code did not work and was generating EFAULT.
Sponsored by <The NetBSD Foundation>
Merge the code back; the problem was that since we are reading/writing
to a kernel address for PT_{READ,WRITE}_{I,D} we need the kernel vmspace.
provide separate read and write functions to accomodate register functions
that need a size argument.
don't ignore error from copyout_piod
Use the proper process (the tracee) to get information about lwps and
registers and the tracer for vmspace.
Add new sysctl(3) entry: security.models.extensions.user_set_dbregs
Model this new sysctl(3) entry after "user_set_cpu_affinity" in the same
level of sysctl(3) switches.
Allow to read unconditionally Debug Registers (no change here). This is
convenient as even if a user of a debugger does not use hardware assisted
watchpoints/breakpoints, a debugger can still prompt these values to store
in an internal cache with context of registers. Reading them should have
no security concerns.
Add a paranoid MI switch that prohibits by default setting these registers
by a regular user (non-superuser). Make this switch disabled by default.
There are enough reserved bits out there to allow using them
unconditionally on hardened hosts.
Features shipped with Debug Registers are optional features in debuggers.
There is no reduction in elementary functionality.

Belatedly catch up with kern_sig.c rev 1.358:
Provide syscall information with SIGTRAP TRAP_SCE/TRAP_SCX so that
picotrace/truss, for example, works fine on COMPAT_NETBSD32.
With some minor changes:
- Centralize netbsd32_si{,32}_si{32,}() into netbsd32_ksi{,32}_ksi{32,}().
- Provide si_status with SIGCHLD.
- Remove the remaining of SA.
Sort by signal numbers as far as possible, adjust locations of functions.
No functional changes intended.
XXX
pullup to netbsd-9
Provide _ptrace_state for SIGTRAP with TRAP_EXEC, TRAP_CHLD, or TRAP_LWP.
Pointed out by kamil. Thanks!
XXX
pullup to netbsd-9
When converting siginfo, examine si_code at the beginning,
as explained in siginfo(2).
- If it is SI_NOINFO, there's no additional information.
- If it is non-positive, i.e., codes described in siginfo(2),
we need to fill in _rt.
XXX
Description for SA_ASYNCIO in siginfo(2) seems outdated;
neither si_fd nor si_band are filled in with that code.
XXX
pullup to netbsd-9
TRAP_EXEC does not have extra fields to be filled in at the moment.
Explicitly ignore fields for now.
