* [PATCH v4 07/16] powerpc: Introduce functions for instruction nullity and equality
From: Jordan Niethe @ 2020-03-20 5:18 UTC (permalink / raw)
To: linuxppc-dev; +Cc: alistair, npiggin, bala24, Jordan Niethe, dja
In-Reply-To: <20200320051809.24332-1-jniethe5@gmail.com>
In preparation for an instruction data type that can not be directly
used with the '==' operator use functions for checking equality and
nullity.

* [PATCH v4 04/16] powerpc: Use a macro for creating instructions from u32s
From: Jordan Niethe @ 2020-03-20 5:17 UTC (permalink / raw)
To: linuxppc-dev; +Cc: alistair, npiggin, bala24, Jordan Niethe, dja
In-Reply-To: <20200320051809.24332-1-jniethe5@gmail.com>
In preparation for instructions having a more complex data type start
using a macro, PPC_INST(), for making an instruction out of a u32.
Currently this does nothing, but it will allow for creating a data type
that can represent prefixed instructions.

* [PATCH v4 03/16] powerpc: Use a datatype for instructions
From: Jordan Niethe @ 2020-03-20 5:17 UTC (permalink / raw)
To: linuxppc-dev; +Cc: alistair, npiggin, bala24, Jordan Niethe, dja
In-Reply-To: <20200320051809.24332-1-jniethe5@gmail.com>
Currently unsigned ints are used to represent instructions on powerpc.
This has worked well as instructions have always been 4 byte words.
However, a future ISA version will introduce some changes to
instructions that mean this scheme will no longer work as well. This
change is Prefixed Instructions. A prefixed instruction is made up of a
word prefix followed by a word suffix to make an 8 byte double word
instruction. No matter the endianess of the system the prefix always
comes first. Prefixed instructions are only planned for powerpc64.
Introduce a ppc_inst type to represent both prefixed and word
instructions on powerpc64 while keeping it possible to exclusively have
word instructions on powerpc32, A latter patch will expand the type to
include prefixed instructions but for now just typedef it to a u32.
Later patches will introduce helper functions and macros for
manipulating the instructions so that powerpc64 and powerpc32 might
maintain separate type definitions.

* [PATCH v4 02/16] xmon: Move out-of-line instructions to text section
From: Jordan Niethe @ 2020-03-20 5:17 UTC (permalink / raw)
To: linuxppc-dev; +Cc: alistair, npiggin, bala24, Jordan Niethe, dja
In-Reply-To: <20200320051809.24332-1-jniethe5@gmail.com>
To execute an instruction out of line after a breakpoint, the NIP is set
to the address of struct bpt::instr. Here a copy of the instruction that
was replaced with a breakpoint is kept, along with a trap so normal flow
can be resumed after XOLing. The struct bpt's are located within the
data section. This is problematic as the data section may be marked as
no execute.
Instead of each struct bpt holding the instructions to be XOL'd, make a
new array, bpt_table[], with enough space to hold instructions for the
number of supported breakpoints. Place this array in the text section.
Make struct bpt::instr a pointer to the instructions in bpt_table[]
associated with that breakpoint. This association is a simple mapping:
bpts[n] -> bpt_table[n * words per breakpoint]. Currently we only need
the copied instruction followed by a trap, so 2 words per breakpoint.

* [PATCH v4 01/16] powerpc/xmon: Remove store_inst() for patch_instruction()
From: Jordan Niethe @ 2020-03-20 5:17 UTC (permalink / raw)
To: linuxppc-dev; +Cc: alistair, npiggin, bala24, Jordan Niethe, dja
In-Reply-To: <20200320051809.24332-1-jniethe5@gmail.com>
For modifying instructions in xmon, patch_instruction() can serve the
same role that store_inst() is performing with the advantage of not
being specific to xmon. In some places patch_instruction() is already
being using followed by store_inst(). In these cases just remove the
store_inst(). Otherwise replace store_inst() with patch_instruction().

* [PATCH v4 00/16] Initial Prefixed Instruction support
From: Jordan Niethe @ 2020-03-20 5:17 UTC (permalink / raw)
To: linuxppc-dev; +Cc: alistair, npiggin, bala24, Jordan Niethe, dja
A future revision of the ISA will introduce prefixed instructions. A
prefixed instruction is composed of a 4-byte prefix followed by a
4-byte suffix.
All prefixes have the major opcode 1. A prefix will never be a valid
word instruction. A suffix may be an existing word instruction or a
new instruction.
This series enables prefixed instructions and extends the instruction
emulation to support them. Then the places where prefixed instructions
might need to be emulated are updated.
The series is based on top of:
https://patchwork.ozlabs.org/patch/1232619/ as this will effect
kprobes.
v4 is based on feedback from Nick Piggins, Christophe Leroy and Daniel Axtens.
The major changes:
- Move xmon breakpoints from data section to text section
- Introduce a data type for instructions on powerpc
v3 is based on feedback from Christophe Leroy. The major changes:
- Completely replacing store_inst() with patch_instruction() in
xmon
- Improve implementation of mread_instr() to not use mread().
- Base the series on top of
https://patchwork.ozlabs.org/patch/1232619/ as this will effect
kprobes.
- Some renaming and simplification of conditionals.
v2 incorporates feedback from Daniel Axtens and and Balamuruhan
S. The major changes are:
- Squashing together all commits about SRR1 bits
- Squashing all commits for supporting prefixed load stores
- Changing abbreviated references to sufx/prfx -> suffix/prefix
- Introducing macros for returning the length of an instruction
- Removing sign extension flag from pstd/pld in sstep.c
- Dropping patch "powerpc/fault: Use analyse_instr() to check for
store with updates to sp" from the series, it did not really fit
with prefixed enablement in the first place and as reported by Greg
Kurz did not work correctly.

Platform needs to define pmd_mknotpresent() for generic pmdp_invalidate()
only when __HAVE_ARCH_PMDP_INVALIDATE is not subscribed. Otherwise platform
specific pmd_mknotpresent() is not required. Hence just drop it.

This series renames pmd_mknotpresent() as pmd_mknotvalid(). Before that it
drops an existing pmd_mknotpresent() definition from powerpc platform which
was never required as it defines it's pmdp_invalidate() through subscribing
__HAVE_ARCH_PMDP_INVALIDATE. This does not create any functional change.
This rename was suggested by Catalin during a previous discussion while we
were trying to change the THP helpers on arm64 platform for migration.
https://patchwork.kernel.org/patch/11019637/
This series is based on v5.6-rc6.
Boot tested on arm64 and x86 platforms.
Built tested on many other platforms including the ones changed here.

Well there's other unnecessary ifdefs in there too I think. But sure.
This patch also got the interrupt_exit_ prototypes leaked in from the
later patch so I could fix those.

Okay.

I could put it all in syscall.c and then we can adjust with some ifdefs
or helpers. I don't think there is enough to be worth syscall.c,
syscall_32.c, and syscall_64.c.
I wonder about the interrupt returns as well, that doesn't really make
sense in a file called syscall.c, but the code is very similar to
system call exit. Should we just call it interrupts.c?

I guess, we can have regs_set_irq_state(regs, IRQS_ENABLED); or
something like that.
We make that helper and a _get_ counterpart in a later patch which
covers other cases in the tree as well.

This goes away with patch 29. Better not to have this ugly thing
spill into ppc32 code at all if we can avoid it :)

Michal pointed this out, he's got patches that do this on top of this
series.
Incremental diff for your suggestions below. Now there is likely we're
going to have a few ifdefs, particularly in the exit paths where we have
complexity handling irq soft masked state where helpers dont make much
sense. I don't think that will be such a bad thing, but we can come to
it as we go.
Thanks,
Nick

* [PATCH v6 1/2] powerpc/64: Setup a paca before parsing device tree etc.
From: Michael Ellerman @ 2020-03-20 3:21 UTC (permalink / raw)
To: linuxppc-dev; +Cc: npiggin, dja
From: Daniel Axtens <dja@axtens.net>
Currently we set up the paca after parsing the device tree for CPU
features. Prior to that, r13 contains random data, which means there
is random data in r13 while we're running the generic dt parsing code.
This random data varies depending on whether we boot through a vmlinux
or a zImage: for the vmlinux case it's usually around zero, but for
zImages we see random values like 912a72603d420015.
This is poor practice, and can also lead to difficult-to-debug
crashes. For example, when kcov is enabled, the kcov instrumentation
attempts to read preempt_count out of the current task, which goes via
the paca. This then crashes in the zImage case.
Similarly stack protector can cause crashes if r13 is bogus, by
reading from the stack canary in the paca.
To resolve this:
- move the paca setup to before the CPU feature parsing.
- because we no longer have access to CPU feature flags in paca
setup, change the HV feature test in the paca setup path to consider
the actual value of the MSR rather than the CPU feature.
Translations get switched on once we leave early_setup, so I think
we'd already catch any other cases where the paca or task aren't set
up.
Boot tested on a P9 guest and host.
Fixes: fb0b0a73b223 ("powerpc: Enable kcov")
Fixes: 06ec27aea9fc ("powerpc/64: add stack protector support")

* [PATCH v6 2/2] powerpc/64: Prevent stack protection in early boot
From: Michael Ellerman @ 2020-03-20 3:21 UTC (permalink / raw)
To: linuxppc-dev; +Cc: npiggin, dja
In-Reply-To: <20200320032116.1024773-1-mpe@ellerman.id.au>
The previous commit reduced the amount of code that is run before we
setup a paca. However there are still a few remaining functions that
run with no paca, or worse, with an arbitrary value in r13 that will
be used as a paca pointer.
In particular the stack protector canary is stored in the paca, so if
stack protector is activated for any of these functions we will read
the stack canary from wherever r13 points. If r13 happens to point
outside of memory we will get a machine check / checkstop.
For example if we modify initialise_paca() to trigger stack
protection, and then boot in the mambo simulator with r13 poisoned in
skiboot before calling the kernel:
DEBUG: 19952232: (19952232): INSTRUCTION: PC=0xC0000000191FC1E8: [0x3C4C006D]: addis r2,r12,0x6D [fetch]

So annotate the relevant functions to ensure stack protection is never
enabled for them.

Oh I see, fwnmi_release_errinfo is done after mce_handle_error, I didnt
read your comment closely!
That means the recovery is done with MSR[ME]=0, which means saving the
SLB entries can take a machine check which will turn into a checkstop,
or walking user page tables and loading memory to handle memory
failures.
We really should release that immediately so we get ME back on.
> So we are good to turn it on here.
Possibly. I don't think it's generally a good idea enable relocation
from an interrupted relocation off context, but yeah this might be okay.
I think FWNMI mce needs to be fixed to not do this, and do the
nmi-interlock earlier, but for now your patch I guess improves things
significantly. So, okay let's go with it.
You should be able to just use mtmsrd to switch to virtual mode, so no
need for the asm code.
mtmsr(mfmsr()|MSR_IR|MSR_DR);
Otherwise,

Yeah, it would only really be used for firmware or certain embedded

Yeah, I'll keep tinkering on it, it might come in useful.

Last time I asked on the list there were still a handful of users.
And I had a patch submitted from a user as recently as last October, so
it still has some life.

There are still PS3-Linux users out there. They generally use firmware
and other tools available through the 'hacker' communities that allow
Linux to be run on more than just the 'officially supported' platforms.
Anyway, the change to use rcuwait seems fine if that's needed for the
completion re-work. I'll try to do some testing with the patch set
next week.

Reading the changelog again...
I have to say that force_dma_unencrypted() makes way more sense in that
context than force_dma_decrypted(). It still wants a comment.
Linguistical semantics and correctness matters a lot. Consistency is
required as well, but not for the price of ambiguous wording.
Thanks,

I have put this series in my kvm-ppc-next branch, and I believe
Michael Ellerman is putting patch 1 in his fixes branch so it gets
into 5.6.
