linux-kselftest-4.14-rc1-update
This update consists of:
-- TAP13 framework API and converting tests to TAP13 continues. A few
more tests are converted and kselftest common RUN_TESTS in lib.mk
is enhanced to print TAP13 to cover test shell scripts that won't
be able to use kselftest API.
-- Several fixes to existing tests to not fail in unsupported cases.
This has been an ongoing work based on the feedback from stable
release kselftest users.
-- A new watchdog test and much needed cleanups to the existing tests
from Eugeniu Rosca.
-- Changes to kselftest common lib.mk framework to make RUN_TESTS a
function to be called from individual test make files to run stress
and destructive sub-tests.

genksyms: fix gperf removal conversion
I had stupidly missed one special use of 'is_reserved_word()' when I
converted the code to avoid gperf.
I had changed that function to return the token ID directly rather than
a pointer to the token descriptor structure, but that meant that the
test for "is this a reserved word" changed from checking the return
value against NULL, to checking that it wasn't negative.
And while I had converted the main token parser over, I missed the
special case of the typeof phrase handling. And since our dependency
chain for genksyms does not include the genksyms program itself
changing, my kernel rebuild didn't show the problem.
Fixes:

RDMA/netlink: clean up message validity array initializer
The fix in the parent made me look at that function, and react to how illogical and illegible the array initializer was. Use named array indexes to make it clearer what is going on, and make the initializer not depend silently on the exact index numbers. [ The initializer now also shows an odd inconsistency in the naming: note the IWCM vs IWPM.. - Linus ] Cc: Leon Romanovsky <leonro@mellanox.com> Cc: Doug Ledford <dledford@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

RDAM/netlink: Fix out-of-bound access while checking message validity
The netlink message sent with type == 0, which doesn't have any client
behind it, caused to the overflow in max_num_ops array.
Fix it by declaring zero number of ops for the first client.

Merge branch 'kvm-ppc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc
This fix was intended for 4.13, but didn't get in because both maintainers were on vacation. Paul Mackerras: "It adds mutual exclusion between list_add_rcu and list_del_rcu calls on the kvm->arch.spapr_tce_tables list. Without this, userspace could potentially trigger corruption of the list and cause a host crash or worse." |

Merge branch 'gperf-removal'
Remove our use of 'gperf' for generating perfect hashes from some of our build tools. This removal was prompted by Masahiro Yamada sending out a patch that removes all our pre-generated files, and when I tested it, I noticed that the gperf version I have (3.1) apparently generates code that no longer works with out code-base because the function interfaces generated by gperf have changed. We really don't care that much, and the gperf people changed their interfaces in ways that makes it annoying to work with them. Tools that make it hard to use them should not be used, and the kernel is not at all interested in some autoconf mess. So remove the gperf dependency entirely. It turns out that if you ignore the pre-generated files, the use of gperf apparently saved us a whopping fifteen lines of code. It obviously wasn't worth it, considering that the pre-generated files are about 500 lines. I sent this out as a patch about three weeks ago, and got absolutely zero responses. So let's see if anybody notices now that I merge it. Because there might be serious bugs here, but it WorksForMe(tm). * gperf-removal: Remove gperf usage from toolchain |

SCSI misc on 20170907
This is mostly updates of the usual suspects: lpfc, qla2xxx, hisi_sas, megaraid_sas, zfcp and a host of minor updates. The major driver change here is the elimination of the block based cciss driver in favour of the SCSI based hpsa driver (which now drives all the legacy cases cciss used to be required for).

This series has the ultimate goal of providing a sane stack rlimit when
running set*id processes. To do this, the bprm_secureexec LSM hook is collapsed into the bprm_set_creds hook so the secureexec-ness of an exec can be determined early enough to make decisions about rlimits and the resulting memory layouts. Other logic acting on the secureexec-ness of an exec is similarly consolidated. Capabilities needed some special handling, but the refactoring removed other special handling, so that was a wash. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: Kees Cook <kees@outflux.net> iQIcBAABCgAGBQJZrwRKAAoJEIly9N/cbcAmhboP/iwLbYfWngIJdu3pYKrW+CEg uUVY6RNnsumJ5yEhD/yQKXSPmZ8PkC8vexPYvf8TcPOlMRQuhVvdiR0FfSUvkMWy pB8ZVCyAV1uSnW4BH61FCxHInrahy8jlvQwnAujvw+FNxhcQjyEGKupOLIMGLioQ 8G5Ihf+hOjiXRhKbXueQi89n8i4jEI5YTH1RnC+Gsy8jG11EC9BhPddKSMaUKZA3 HYYqUyV0daYpGuxTOxaRdDO5wb6rlS+B46hqtOsSsIBOQkCjnLCRcdeMCqvXjQmv kyZj03cPlUjEHqh3d3nB6utvVWReGf/p986//kQjT1OZPhATbySAu7wUHoLik3dU zuexudNTBROf6YXahMxSJp348GS++xoBFARa78402E++U7C4/eoclbLCWAylBwVA H+QAHFYRC2WFoskejSYBRPz6HLr1SIaSYMsKbkHqP07zi6p3ic2Uq3XvOP2zL/5p l/mXa1Fs2vcDOWPER8a8b9mVkJDvuXj6J11lG+q80UWAWC3sd9GkSwOen80ps3Xo /7dd+h2BAJSSVxZQFxd5YCx99mT0ntQZ797PhjxOY6SX/xUdOCAp9x1zDU5OUovP q2ty3UTd7tq8h1RnHOnrn9cKmMmI7kpBvEfPGM507cEVjyfsMu2jJtUxN9dXOAkB aebEsg3C8M6z5OdGVpWH =Yva4 -----END PGP SIGNATURE----- Merge tag 'secureexec-v4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull secureexec update from Kees Cook: "This series has the ultimate goal of providing a sane stack rlimit when running set*id processes.

Pull media updates from Mauro Carvalho Chehab:
"Brazil's Independence Day pull request :-)
This is one of the biggest media pull requests, with 625 patches
affecting almost all parts of media (RC, DVB, V4L2, CEC, docs).
This contains:
- A lot of new drivers:
* DVB frontends: mxl5xx, stv0910, stv6111;
* camera flash: as3645a led driver;
* HDMI receiver: adv748X;
* camera sensor: Omnivision 6650 5M driver (ov6650);
* HDMI CEC: ao-cec meson driver;
* V4L2: Qualcom camss driver;
* Remote controller: gpio-ir-tx, pwm-ir-tx and zx-irdec drivers.
- The DDbridge DVB driver got a massive update, with makes it in sync
with modern hardware from that vendor;
- There's an important milestone on this series: the DVB
documentation was written in 2003, but only started to be updated
in 2007. It also used to contain several gaps from the time it was
kept out of tree, mentioning error codes and device nodes that
never existed upstream. On this series, it received a massive
update: all non-deprecated digital TV APIs are now in sync with the
current implementation;
- Some DVB APIs that aren't used by any upstream driver got removed;
- Other parts of the media documentation algo got updated, fixing
some bugs on its PDF output and making it compatible with Sphinx
version 1.6.
As the number of hacks required to build PDF output reduced, I hope
we'll have less troubles as newer versions of our documentation
toolchain are released (famous last words);
- As usual, lots of driver cleanups and improvements"

sound updates for 4.14-rc1
We have touched quite a lot of files but with fewer changes at this
cycle; as you can see, most of changes are trivial fixes, especially
constification patches. Among the massive attacks by constification
gangs, we had a few core changes (mostly for ASoC core), as well the
fixes and the updates by major vendors. Some highlights are below:
ALSA core:
- Fix possible races in control API user-TLV codes
- Small cleanup of PCM core
ASoC:
- Continued work for componentization; still half-baked, but we're
certainly progressing
- Use of devres for jack detection GPIOs, rather as a cleanup
- Jack detection support for Qualcomm MSM8916
- Support for Allwinner H3, Cirrus Logic CS43130, Intel Kabylake
systems with RT5663, Realtek RT274, TI TLV320AIC32x6 and Wolfson

Pull block layer updates from Jens Axboe:
"This is the first pull request for 4.14, containing most of the code
changes. It's a quiet series this round, which I think we needed after
the churn of the last few series. This contains:
- Fix for a registration race in loop, from Anton Volkov.
- Overflow complaint fix from Arnd for DAC960.
- Series of drbd changes from the usual suspects.
- Conversion of the stec/skd driver to blk-mq. From Bart.
- A few BFQ improvements/fixes from Paolo.
- CFQ improvement from Ritesh, allowing idling for group idle.
- A few fixes found by Dan's smatch, courtesy of Dan.
- A warning fixup for a race between changing the IO scheduler and
device remova. From David Jeffery.

powerpc updates for 4.14
Nothing really major this release, despite quite a lot of activity. Just lots of
things all over the place.
Some things of note include:
- Access via perf to a new type of PMU (IMC) on Power9, which can count both
core events as well as nest unit events (Memory controller etc).
- Optimisations to the radix MMU TLB flushing, mostly to avoid unnecessary Page
Walk Cache (PWC) flushes when the structure of the tree is not changing.
- Reworks/cleanups of do_page_fault() to modernise it and bring it closer to
other architectures where possible.
- Rework of our page table walking so that THP updates only need to send IPIs
to CPUs where the affected mm has run, rather than all CPUs.
- The size of our vmalloc area is increased to 56T on 64-bit hash MMU systems.
This avoids problems with the percpu allocator on systems with very sparse
NUMA layouts.
- STRICT_KERNEL_RWX support on PPC32.
- A new sched domain topology for Power9, to capture the fact that pairs of
cores may share an L2 cache.
- Power9 support for VAS, which is a new mechanism for accessing coprocessors,
and initial support for using it with the NX compression accelerator.
- Major work on the instruction emulation support, adding support for many new
instructions, and reworking it so it can be used to implement the emulation
needed to fixup alignment faults.
- Support for guests under PowerVM to use the Power9 XIVE interrupt controller.
And probably that many things again that are almost as interesting, but I had to
keep the list short. Plus the usual fixes and cleanups as always.

Pull EFI updates from Ingo Molnar:
"The main changes in this cycle were:
- Transparently fall back to other poweroff method(s) if EFI poweroff
fails (and returns)
- Use separate PE/COFF section headers for the RX and RW parts of the
ARM stub loader so that the firmware can use strict mapping
permissions
- Add support for requesting the firmware to wipe RAM at warm reboot
- Increase the size of the random seed obtained from UEFI so CRNG
fast init can complete earlier
- Update the EFI framebuffer address if it points to a BAR that gets
moved by the PCI resource allocation code
- Enable "reset attack mitigation" of TPM environments: this is
enabled if the kernel is configured with
CONFIG_RESET_ATTACK_MITIGATION=y.
- Clang related fixes
- Misc cleanups, constification, refactoring, etc"

Merge branch 'kvm-ppc-next' of git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc
KVM/PPC update for 4.14 There are various minor fixes and cleanups. The only new feature is that we now export information about storage key support to userspace, so it can advertise it to the guest. I have pulled in Michael Ellerman's topic/ppc-kvm branch from the powerpc tree to get a couple of fixes that touch both KVM PPC code and other PPC code. That's why there is some arch/powerpc stuff in the diffstat that isn't arch/powerpc/kvm. |

fs: aio: fix the increment of aio-nr and counting against aio-max-nr
Currently, aio-nr is incremented in steps of 'num_possible_cpus() * 8'
for io_setup(nr_events, ..) with 'nr_events < num_possible_cpus() * 4':
ioctx_alloc()
...
nr_events = max(nr_events, num_possible_cpus() * 4);
nr_events *= 2;
...
ctx->max_reqs = nr_events;
...
aio_nr += ctx->max_reqs;
....
This limits the number of aio contexts actually available to much less
than aio-max-nr, and is increasingly worse with greater number of CPUs.
For example, with 64 CPUs, only 256 aio contexts are actually available
(with aio-max-nr = 65536) because the increment is 512 in that scenario.
Note: 65536 [max aio contexts] / (64*4*2) [increment per aio context]
is 128, but make it 256 (double) as counting against 'aio-max-nr * 2':
ioctx_alloc()
...
if (aio_nr + nr_events > (aio_max_nr * 2UL) ||
...
goto err_ctx;
...
This patch uses the original value of nr_events (from userspace) to
increment aio-nr and count against aio-max-nr, which resolves those.

Pull percpu updates from Tejun Heo: "A lot of changes for percpu this time around. percpu inherited the same area allocator from the original pre-virtual-address-mapped implementation. This was from the time when percpu allocator wasn't used all that much and the implementation was focused on simplicity, with the unfortunate computational complexity of O(number of areas allocated from the chunk) per alloc / free. With the increase in percpu usage, we're hitting cases where the lack of scalability is hurting. The most prominent one right now is bpf perpcu map creation / destruction which may allocate and free a lot of entries consecutively and it's likely that the problem will become more prominent in the future. To address the issue, Dennis replaced the area allocator with hinted bitmap allocator which is more consistent. While the new allocator does perform a bit worse in some cases, it outperforms the old allocator way more than an order of magnitude in other more common scenarios while staying mostly flat in CPU overhead and completely flat in memory consumption" * 'for-4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu: (27 commits) percpu: update header to contain bitmap allocator explanation. percpu: update pcpu_find_block_fit to use an iterator percpu: use metadata blocks to update the chunk contig hint percpu: update free path to take advantage of contig hints percpu: update alloc path to only scan if contig hints are broken percpu: keep track of the best offset for contig hints percpu: skip chunks if the alloc does not fit in the contig hint percpu: add first_bit to keep track of the first free in the bitmap percpu: introduce bitmap metadata blocks percpu: replace area map allocator with bitmap percpu: generalize bitmap (un)populated iterators percpu: increase minimum percpu allocation size and align first regions percpu: introduce nr_empty_pop_pages to help empty page accounting percpu: change the number of pages marked in the first_chunk pop bitmap percpu: combine percpu address checks percpu: modify base_addr to be region specific percpu: setup_first_chunk rename schunk/dchunk to chunk percpu: end chunk area maps page aligned for the populated bitmap percpu: unify allocation of schunk and dchunk percpu: setup_first_chunk remove dyn_size and consolidate logic ... |

x86/mm: Reinitialize TLB state on hotplug and resume
When Linux brings a CPU down and back up, it switches to init_mm and then
loads swapper_pg_dir into CR3. With PCID enabled, this has the side effect
of masking off the ASID bits in CR3.
This can result in some confusion in the TLB handling code. If we
bring a CPU down and back up with any ASID other than 0, we end up
with the wrong ASID active on the CPU after resume. This could
cause our internal state to become corrupt, although major
corruption is unlikely because init_mm doesn't have any user pages.
More obviously, if CONFIG_DEBUG_VM=y, we'll trip over an assertion
in the next context switch. The result of *that* is a failure to
resume from suspend with probability 1 - 1/6^(cpus-1).
Fix it by reinitializing cpu_tlbstate on resume and CPU bringup.

tracing: Apply trace_clock changes to instance max buffer
Currently trace_clock timestamps are applied to both regular and max
buffers only for global trace. For instance trace, trace_clock
timestamps are applied only to regular buffer. But, regular and max
buffers can be swapped, for example, following a snapshot. So, for
instance trace, bad timestamps can be seen following a snapshot.
Let's apply trace_clock timestamps to instance max buffer as well.

mm,fork: introduce MADV_WIPEONFORK
Introduce MADV_WIPEONFORK semantics, which result in a VMA being empty
in the child process after fork. This differs from MADV_DONTFORK in one
important way.
If a child process accesses memory that was MADV_WIPEONFORK, it will get
zeroes. The address ranges are still valid, they are just empty.
If a child process accesses memory that was MADV_DONTFORK, it will get a
segmentation fault, since those address ranges are no longer valid in
the child after fork.
Since MADV_DONTFORK also seems to be used to allow very large programs
to fork in systems with strict memory overcommit restrictions, changing
the semantics of MADV_DONTFORK might break existing programs.
MADV_WIPEONFORK only works on private, anonymous VMAs.
The use case is libraries that store or cache information, and want to
know that they need to regenerate it in the child process after fork.
Examples of this would be:
- systemd/pulseaudio API checks (fail after fork) (replacing a getpid
check, which is too slow without a PID cache)
- PKCS#11 API reinitialization check (mandated by specification)
- glibc's upcoming PRNG (reseed after fork)
- OpenSSL PRNG (reseed after fork)
The security benefits of a forking server having a re-inialized PRNG in
every child process are pretty obvious. However, due to libraries
having all kinds of internal state, and programs getting compiled with
many different versions of each library, it is unreasonable to expect
calling programs to re-initialize everything manually after fork.
A further complication is the proliferation of clone flags, programs
bypassing glibc's functions to call clone directly, and programs calling
unshare, causing the glibc pthread_atfork hook to not get called.
It would be better to have the kernel take care of this automatically.
The patch also adds MADV_KEEPONFORK, to undo the effects of a prior
MADV_WIPEONFORK.
This is similar to the OpenBSD minherit syscall with MAP_INHERIT_ZERO:
