Fix endian issue with UDF extended attribute handling

Implement support for mounting UDF in compat32
Fixes PR#56801

Adapt to recent posix_spawn extensions.

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.

Introduce PT_LWPSTATUS + PT_LWPNEXT, obsolete PT_LWPINFO

PT_LWPINFO is a legacy ptrace(2) operation that was originally intended
to retrieve the thread (LWP) information inside a traced process.

It has a number of flaws and is confused with PT_LWPINFO from FreeBSD.

PT_LWPSTATUS and PT_LWPNEXT address the problems (shortly by: rename,
removal of pl_event) and introduces new features: signal context
(pl_sigpend, pl_sigmask), LWP name (pl_name), LWP TLS base address
(pl_private). The private pointer was so far missing information for
a debugger.

PT_LWPSTATUS@nnn is now shipped with core(5) files and contain LWP specific
information, so far missed in the core(5) files.

PT_LWPSTATUS retrieves LWP information for the prompted thread.
PT_LWPNEXT retrieves LWP information for the next thread, borrowing the
semantics from NetBSD specific PT_LWPINFO.

PT_LWPINFO is namespaced with __LEGACY_PT_LWPINFO and still available for
the foreseeable future, without plans of removing it.

Add ATF tests for PT_LWPSTATUS + PT_LWPNEXT.

Keep ATF tests for PT_LWPINFO.

Switch GDB to new API.

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).

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.

We never exec(2) with a kernel vmspace, so do not test for that, but instead
KASSERT() that we don't.
When calculating the load address for the interpreter (e.g. ld.elf_so),
we need to take into account wether the exec'd process will run with
topdown memory or bottom up. We can not use the current vmspace's flags
to test for that, as this happens too early. Luckily the execpack already
knows what the new state will be later, so instead of testing the current
vmspace, pass the info as additional argument to struct emul
e_vm_default_addr.
Fix all such functions and adopt all callers.

If you're going to change the name of something, you need to change
the name of *all* the things with the same name, not just a handful,
and you should change it to something similar so it still matches the
rest of the system rather than just picking an arbitrarily different
name.

Hi, Joerg.

To wit, rename the quotactl "delete" operation to "del", because
"delete" is a reserved word in C++ and for some reason Joerg wants to
run internal interfaces used only by C code through his C++ compiler.
Do not rename it to "remove" instead, because this doesn't match
libquota or the rest of the usage throughout the system; and rename
all the related identifiers, not just the ones that blew the mind of
Joerg's C++ compiler.

Because this is not a user-facing API (the only userland consumer
sys/quotactl.h is libquota) it is sort of ok to make arbitrary
source-incompatible changes; however, by the same token it's completely
unnecessary. If it *were* a user-facing API that someone might have a
semi-rational reason to want to run a C++ compiler on, it would be
incorrect to change it at this point.

Be consistent about whether idtype and objtype codes are signed or

choice, it doesn't really matter and the majority of preexisting uses
were signed. And consistency is good.)

Improve the names of some members of struct quotactl_args. These are

Add netbsd32_socklenp_t

As a precaution, add sys/param.h explicitly to some headers that will
no longer get it via sys/ucred.h and don't already include it
explicitly. These should in turn be removed when it can be confirmed
that it's safe to do so. (Because sys/param.h is full of things that
are often tested with #if, it's not in general safe to remove it
without checking, as such tests fail silently if the symbol goes
missing.)

merge the bouyer-quota2 branch. This adds a new on-disk format
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

remove clause #3 from my license where there are no other

Fix netbsd32_ipc_perm and netbsd32_shmid_ds structures to use correct
types.

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.

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.

Define netbsd32_uint64 for 64bit integers with the alignment requirement
of the corresponding 32bit architecture.
Use it for the 64bit items in netbsd32_statvfs so that the structure

This replaces the 'packed' attribute which wasn't architecture specific

Change all the NETBSD32PTR64(SCARG(uap, xxx))) to SCARG_P32(uap, xxx).

First attempt to bring branch in sync with HEAD

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.

adjust limits takes struct proc again.

From Nicolas Joly:

> It seems that 32bits programs, running under compat_netbsd32, using
> setrlimit force all other programs to have their maximum data size
> fixed at 3GB, where native 64bits apps used 8GB previously.

I tracked this one to the `netbsd32_adjust_limits()' function (called
when creating a new process under compat_netbsd32), where data and
stack limits are set without checking for shared `p_limit' structure
(p_limit->p_refcnt > 1). This explain the side effect where processes
have their limits changed when a compat_netbsd32 (or compat_linux32)
program is run.

The fix is to use `dosetrlimit()' to ensure the needed copy-on-write
behaviour for shared structure.

Move prototypes for siginfo32 to/from siginfo converters at the right

  operations.  This is similar to what was done in FreeBSD by Paul Saab.

- Add the COMPAT_NETBSD32 definitions and hooks.

Fix some things regarding COMPAT_NETBSD32 and limits/VM addresses.
* For sparc64 and amd64, define *SIZ32 VM constants.
* Add a new function pointer to struct emul, pointing at a function
  that will return the default VM map address. The default function
  is uvm_map_defaultaddr, which just uses the VM_DEFAULT_ADDRESS
  macro. This gives emulations control over the default map address,
  and allows things to be mapped at the right address (in 32bit range)
  for COMPAT_NETBSD32.
* Add code to adjust the data and stack limits when a COMPAT_NETBSD32
  or COMPAT_SVR4_32 binary is executed.
* Don't use USRSTACK in kern_resource.c, use p_vmspace->vm_minsaddr
  instead (emulations might have set it differently)
* Since this changes struct emul, bump kernel version to 3.99.2

method of doing i/o to change without affecting any future MD code.
Also, make netbsd32_core.c [re]use core_netbsd.c (in a similar manner that
core_elf64.c uses core_elf32.c) and eliminate that code duplication.
cpu_coredump{,32} is now called twice, first with a NULL iocookie to fill
the core structure and a second to actually write md parts of the coredump.
All i/o is nolonger random access and is suitable for shipping over a stream.
