On POWER9, if the hypervisor supports XIVE exploitation mode, the guest OS
will unconditionally requests for the XIVE interrupt mode even if XIVE was
deactivated with the kernel command line xive=off. Later on, when the spapr
XIVE init code handles xive=off, it disables XIVE and tries to fall back on
the legacy mode XICS.
This discrepency causes a kernel panic because the hypervisor is configured
to provide the XIVE interrupt mode to the guest :

Look for xive=off during prom_init and don't ask for XIVE in this case. One
exception though: if the host only supports XIVE, we still want to boot so
we ignore xive=off.
Similarly, have the spapr XIVE init code to looking at the interrupt mode
negociated during CAS, and ignore xive=off if the hypervisor only supports
XIVE.

eac1e731b59e is a v4.16 commit actually but this patch only applies
cleanly to v4.20 and newer. If needed I can send a backport for
older versions.

* Latest Git kernel: Section mismatch in reference from the variable start_here_multiplatform to the function .init.text:.early_setup()
From: Christian Zigotzky @ 2019-05-15 10:09 UTC (permalink / raw)
To: linuxppc-dev, Christian Zigotzky

Hi All,
I got the following error messages with the latest Git kernel today:
GEN .version
CHK include/generated/compile.h
LD vmlinux.o
MODPOST vmlinux.o
WARNING: vmlinux.o(.text+0x302a): Section mismatch in reference from the
variable start_here_multiplatform to the function .init.text:.early_setup()
The function start_here_multiplatform() references
the function __init .early_setup().
This is often because start_here_multiplatform lacks a __init
annotation or the annotation of .early_setup is wrong.
MODINFO modules.builtin.modinfo
KSYM .tmp_kallsyms1.o
KSYM .tmp_kallsyms2.o
LD vmlinux
SORTEX vmlinux
SYSMAP System.map
CHKHEAD vmlinux
What does it mean?
Please find attached the kernel config.
Thanks,
Christian

* [PATCH] crypto: vmx - CTR: always increment IV as quadword
From: Daniel Axtens @ 2019-05-15 10:24 UTC (permalink / raw)
To: mpe, ebiggers, linux-crypto, Herbert Xu
Cc: leo.barbosa, Stephan Mueller, nayna, omosnacek, leitao, pfsmorigo,
marcelo.cerri, gcwilson, linuxppc-dev
The kernel self-tests picked up an issue with CTR mode:
alg: skcipher: p8_aes_ctr encryption test failed (wrong result) on test vector 3, cfg="uneven misaligned splits, may sleep"
Test vector 3 has an IV of FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFD, so
after 3 increments it should wrap around to 0.
In the aesp8-ppc code from OpenSSL, there are two paths that
increment IVs: the bulk (8 at a time) path, and the individual
path which is used when there are fewer than 8 AES blocks to
process.
In the bulk path, the IV is incremented with vadduqm: "Vector
Add Unsigned Quadword Modulo", which does 128-bit addition.
In the individual path, however, the IV is incremented with
vadduwm: "Vector Add Unsigned Word Modulo", which instead
does 4 32-bit additions. Thus the IV would instead become
FFFFFFFFFFFFFFFFFFFFFFFF00000000, throwing off the result.
Use vadduqm.
This was probably a typo originally, what with q and w being
adjacent. It is a pretty narrow edge case: I am really
impressed by the quality of the kernel self-tests!

I'll pass this along internally to get it into OpenSSL as well.

* [PATCH 1/2] pid: add pidfd_open()
From: Christian Brauner @ 2019-05-15 10:03 UTC (permalink / raw)
To: jannh, oleg, viro, torvalds, linux-kernel, arnd, dhowells
Cc: linux-ia64, linux-sh, linux-mips, linux-kselftest, sparclinux,

akpm, linuxppc-dev
This adds the pidfd_open() syscall. It allows a caller to retrieve pollable
pidfds for a process which did not get created via CLONE_PIDFD, i.e. for a
process that is created via traditional fork()/clone() calls that is only
referenced by a PID:
int pidfd = pidfd_open(1234, 0);
ret = pidfd_send_signal(pidfd, SIGSTOP, NULL, 0);
With the introduction of pidfds through CLONE_PIDFD it is possible to
created pidfds at process creation time.
However, a lot of processes get created with traditional PID-based calls
such as fork() or clone() (without CLONE_PIDFD). For these processes a
caller can currently not create a pollable pidfd. This is a huge problem
for Android's low memory killer (LMK) and service managers such as systemd.
Both are examples of tools that want to make use of pidfds to get reliable
notification of process exit for non-parents (pidfd polling) and race-free
signal sending (pidfd_send_signal()). They intend to switch to this API for
process supervision/management as soon as possible. Having no way to get
pollable pidfds from PID-only processes is one of the biggest blockers for
them in adopting this api. With pidfd_open() making it possible to retrieve
pidfd for PID-based processes we enable them to adopt this api.
In line with Arnd's recent changes to consolidate syscall numbers across
architectures, I have added the pidfd_open() syscall to all architectures
at the same time.

* [PATCH 2/2] tests: add pidfd_open() tests

In-Reply-To: <20190515100400.3450-1-christian@brauner.io>
This adds testing for the new pidfd_open() syscalls. Specifically, we test:
- that no invalid flags can be passed to pidfd_open()
- that no invalid pid can be passed to pidfd_open()
- that a pidfd can be retrieved with pidfd_open()
- that the retrieved pidfd references the correct pid

From: Josh Poimboeuf <jpoimboe@redhat.com>
commit 98af8452945c55652de68536afdde3b520fec429 upstream.
Keeping track of the number of mitigations for all the CPU speculation
bugs has become overwhelming for many users. It's getting more and more
complicated to decide which mitigations are needed for a given
architecture. Complicating matters is the fact that each arch tends to
have its own custom way to mitigate the same vulnerability.
Most users fall into a few basic categories:
a) they want all mitigations off;
b) they want all reasonable mitigations on, with SMT enabled even if
it's vulnerable; or
c) they want all reasonable mitigations on, with SMT disabled if
vulnerable.
Define a set of curated, arch-independent options, each of which is an
aggregation of existing options:
- mitigations=off: Disable all mitigations.
- mitigations=auto: [default] Enable all the default mitigations, but
leave SMT enabled, even if it's vulnerable.
- mitigations=auto,nosmt: Enable all the default mitigations, disabling
SMT if needed by a mitigation.
Currently, these options are placeholders which don't actually do
anything. They will be fleshed out in upcoming patches.

* [PATCH] powerpc: silence a -Wcast-function-type warning in dawr_write_file_bool
From: Mathieu Malaterre @ 2019-05-15 12:09 UTC (permalink / raw)
To: Michael Ellerman
Cc: Michael Neuling, Mathieu Malaterre, linux-kernel, Paul Mackerras,
linuxppc-dev
In commit c1fe190c0672 ("powerpc: Add force enable of DAWR on P9
option") the following piece of code was added:
smp_call_function((smp_call_func_t)set_dawr, &null_brk, 0);
Since GCC 8 this trigger the following warning about incompatible
function types:
arch/powerpc/kernel/hw_breakpoint.c:408:21: error: cast between incompatible function types from 'int (*)(struct arch_hw_breakpoint *)' to 'void (*)(void *)' [-Werror=cast-function-type]
Cast the function to an intermediate (void*) to make the compiler loose
knowledge about actual type.

I think that would work, if I understand synchronize_rcu_tasks().
I worry that it will make the enable/disable expensive. But could be
worth trying.

* [PATCH] crypto: talitos - fix skcipher failure due to wrong output IV

This above dumps show that the actual output IV is indeed the input IV.
This is due to the IV not being copied back into the request.
This patch fixes that.

Ok, can someone send me a backport that actually applies there?

And the warning is there for a reason, and should not be hidden
behind a cast. This should instead be fixed by something like this:

* [RFC PATCH 1/5] mm: large system hash use vmalloc for size > MAX_ORDER when !hashdist
From: Nicholas Piggin @ 2019-05-15 13:19 UTC (permalink / raw)
To: linuxppc-dev, linux-mm; +Cc: Linus Torvalds, Nicholas Piggin
The kernel currently clamps large system hashes to MAX_ORDER when
hashdist is not set, which is rather arbitrary.
vmalloc space is limited on 32-bit machines, but this shouldn't
result in much more used because of small physical memory.

hashdist currently always uses vmalloc when hashdist is true. When
there is only 1 online node and size <= MAX_ORDER, vmalloc can be
avoided.

* [RFC PATCH 3/5] mm/vmalloc: Hugepage vmalloc mappings
From: Nicholas Piggin @ 2019-05-15 13:19 UTC (permalink / raw)

In-Reply-To: <20190515131944.12489-1-npiggin@gmail.com>
This appears to help cached git diff performance by about 5% on a
POWER9 (with 32MB dentry cache hash).
Profiling git diff dTLB misses with a vanilla kernel:
81.75% git [kernel.vmlinux] [k] __d_lookup_rcu
7.21% git [kernel.vmlinux] [k] strncpy_from_user
1.77% git [kernel.vmlinux] [k] find_get_entry
1.59% git [kernel.vmlinux] [k] kmem_cache_free
40,168 dTLB-miss
0.100342754 seconds time elapsed
After this patch (and the subsequent powerpc HUGE_VMAP patches), the
dentry cache hash gets mapped with 2MB pages:
2,987 dTLB-miss
0.095933138 seconds time elapsed
elapsed time improvement isn't too scientific but seems consistent,
TLB misses certainly improves an order of magnitude. My laptop
takes a lot of misses here too, so x86 would be interesting to test,
I think it should just work there.

This does not actually enable huge vmap mappings, because powerpc/64
ioremap does not call ioremap_page_range, but it is required before
implementing huge mappings in ioremap, because the generic vunmap code
needs to cope with them.

[Backport of upstream commit b45ba4a51cde29b2939365ef0c07ad34c8321789]
On powerpc32, patch_instruction() is called by apply_feature_fixups()
which is called from early_init()
There is the following note in front of early_init():
* Note that the kernel may be running at an address which is different
* from the address that it was linked at, so we must use RELOC/PTRRELOC
* to access static data (including strings). -- paulus
Therefore init_mem_is_free must be accessed with PTRRELOC()

Can't apply the upstream commit as such due to several other unrelated stuff
like for instance STRICT_KERNEL_RWX which are missing.
So instead, using same approach as for commit 252eb55816a6f69ef9464cad303cdb3326cdc61d
Removed the Fixes: tag as I don't know yet the commit Id of the fixed commit on 4.4 branch.
