Add tests of rtcache invalidation
Remove unnecessary NULL check of rt_ifp
It's always non-NULL.
Invalidate rtcache based on a global generation counter
The change introduces a global generation counter that is incremented when any
routes have been added or deleted. When a rtcache caches a rtentry into itself,
it also stores a snapshot of the generation counter. If the snapshot equals to
the global counter, the cache is still valid, otherwise invalidated.
One drawback of the change is that all rtcaches of all protocol families are
invalidated when any routes of any protocol families are added or deleted.
If that matters, we should have separate generation counters based on
protocol families.
This change removes LIST_ENTRY from struct route, which fixes a part of
PR kern/52515.
Remove the global lock for rtcache
Thanks to removal of LIST_ENTRY of struct route, rtcaches are accessed only by
their users. And in existing usages a rtcache is guranteed to be not accessed
simultaneously. So the rtcache framework doesn't need any exclusion controls
in itself.
Synchronize on rtcache_generation with rtlock
It's racy if NET_MPSAFE is enabled.

1.198.12.2 Wed May 14 01:34:59 UTC 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.
1.198.12.1 Sat May 10 23:48:43 UTC 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.

Fixes silent hangup right after starting a kernel on my

Reviewed by soda@. Maybe other ARC machines are also affected.

Shrink ramdisk to make RAMDISK kernel smaller for ARC BIOS restriction.

Try to shrink kernels to smaller than ~6MB due to ARC BIOS restriction.

Currently NetBSD/arc kernels are loaded at 0x80200000
(on some machines ARC BIOS uses regions before it) and
ARC BIOS also uses around 0x807f0000, so bootloader fails
on loading >6MB kernels.

Note GXemul doesn't have this restriction because it loads
a kernel directly via a command line argument.

Tested by installing using sysinst on RAMDISK kernel on netbsd-9.

PUFFS direct I/O cache fix

There are a few situations where we must take care of the cache if direct
I/O was enabled:
- if we do direct I/O for write but not for read, then any write must
invalidate the cache so that a reader gets the written data and not
the not-updated cache.
- if we used a vnode without direct I/O and it is enabled for writing,
we must flush the cache before compeling the open operation, so that
the cachec write are not lost.

And at inactive time, we wipe direct I/O flags so that a new open without
direct I/O does not inherit direct I/O.

sys/fs/puffs/puffs_vnops.c: revision 1.198
PUFFS direct I/O cache fix
There are a few situations where we must take care of the cache if
direct
I/O was enabled:
- if we do direct I/O for write but not for read, then any write must
invalidate the cache so that a reader gets the written data and not
the not-updated cache.
- if we used a vnode without direct I/O and it is enabled for writing,
we must flush the cache before compeling the open operation, so that
the cachec write are not lost.
And at inactive time, we wipe direct I/O flags so that a new open
without
direct I/O does not inherit direct I/O.

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

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.

x86/errata.c: Link to original AMD errata guide.

This one is no longer updated; need to link to newer ones for
individual families too. That's where all the cryptic nomenclature
comes from here.

x86/errata.c: Say what revision we're searching for.

x86/errata.c: Only say the errata revision search for cpu0.

x86: make the CPUID list for errata be far less confusing
the 0x80000001 CPUID result needs some parsing to match against
actual family/model/stepping values. 4-bit 'family' values of
15 or 6 change how to parse the 4-bit extended model and 8-bit
extended family value - for family 6 or 15, the extended model
bits (4) are concatenated with the base 4-bits to create an
8-bit value, and for family 15, the family value is addition
of the family value and the 8-bit extended-family value, giving
a range of 0 to 15 + 0xff aka 270.

use a CPUREV(family, model, stepping) macro that builds the
relevant bit-representation of a CPUID, making it far easier
to understand what each entry means, and to add new ones too.
i have confirmed that the emitted cpurevs[] array has the same
values before/after this change, ie, NFCI or observed.

x86: add names for errata that don't have actual numbers
zenbleed is reported as "erratum 65535" currently, this adds a name
for it, and enables the name for any others as well.
pull logging into a function with a tag message.

x86: handle AMD errata 1474: A CPU core may hang after about 1044 days
from the new comment:
* This requires disabling CC6 power level, which can be a performance
* issue since it stops full turbo in some implementations (eg, half the
* cores must be in CC6 to achieve the highest boost level.) Set a timer
* to fire in 1000 days -- except NetBSD timers end up having a signed
* 32-bit hz-based value, which rolls over in under 25 days with HZ=1000,
* and doing xcall(9) or kthread(9) from a callout is not allowed anyway,
* so just have a kthread wait 1 day for 1000 times.
documented in:
https://www.amd.com/content/dam/amd/en/documents/processor-tech-docs/revision-guides/56323-PUB_1_01.pdf

add MSR stuff for AMD errata 1474.

1.198.2.5 Sat Jul 20 14:19:31 UTC 2024 martin Pull up following revision(s) (requested by andvar in ticket #738):

sys/arch/x86/x86/identcpu.c: revision 1.129
sys/arch/x86/include/specialreg.h: revision 1.212
sys/arch/x86/x86/identcpu.c: revision 1.130

Disable the VIA Alternate Instructions according the VIA documentation:
* C7 and above do not support ALTINST, do not check or attempt to disable them.
* For VIA C3 Nehemiah check extended feature flags for support and status,
do no attempt to disable when AIS is not supported or enabled.
* For pre-Nehemiah models explicitly disable, if they are in the range
of documented models, flags aren't present to check the status on
these models.

Note: for pre-Nehemiah may be other functional side effects depdending
on the version and stepping.

Explicit disabling of ALTINST was introduced with rev. 1.84 following
the discovery of some VIA CPUs having these instructions enabled by default
leading to the potential backdoor (aka rosenbrindge).

Unfortunately, implementation used a wrong check (ACE supported flag),
which can be true for the later models, still supporting padlock features.

Setting ALTINST bit on those may have unexpected side effects like VIA C7 CPUID
instruction for temperature sensor not reporting correct value or
`cpuctl identify' not reporting certain CPU features. Similar side effects
can be observed even for Nehemiah models not supporting AIS instructions. This
change should limit possibility of such issues to only the pre-Nehemiah models,
not covered at all in the previous implementation.

Feature Control Register (FCR) macros were unified under one group and
consistent naming while implementing the change. Few comments updated as well.
patch reviewed by Riastradh@ (thank you)

PR kern/58370

Move determination of the largest VIA CPU extended function value
to the intended place where the checks are performed.
Currently the value can be overridden while checking for the padlock features,
and failing the check for max function value as a result.

x86: turn off zenbleed chicken bit on Zen2 cpus.

this is based upon Taylor's original work. i just made the list
of CPUs to run on correct as i could determine. (also, add some
Zen3 and Zen4 cpuids not yet used by any errata.)

(might be nice to have a better way to expression revision ranges
rather than specific cpuid matches, eg, 0x30-0x4f models in a cpu
family, etc.)

tested on ryzen 3600, and a ported zenbleed PoC that no longer
shows any obtained text. (a similar module-version of it stopped
the PoC on a ryzen 3950x without having to reboot.)

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.
