6a61b70b43 gcov: remove CONFIG_GCOV_FORMAT_AUTODETECT
CONFIG_GCOV_FORMAT_AUTODETECT compiles either gcc_3_4.c or gcc_4_7.c
according to your GCC version.

We can achieve the equivalent behavior by setting reasonable dependency
with the knowledge of the compiler version.

If GCC older than 4.7 is used, GCOV_FORMAT_3_4 is the default, but users
are still allowed to select GCOV_FORMAT_4_7 in case the newer format is
back-ported.

On the other hand, If GCC 4.7 or newer is used, there is no reason to
use GCOV_FORMAT_3_4, so it should be hidden.

If you downgrade the compiler to GCC 4.7 or older, oldconfig/syncconfig
will display a prompt for the choice because GCOV_FORMAT_3_4 becomes
visible as a new symbol.

2a61f4747e stack-protector: test compiler capability in Kconfig and drop AUTO mode
Move the test for -fstack-protector(-strong) option to Kconfig.

If the compiler does not support the option, the corresponding menu
is automatically hidden.  If STRONG is not supported, it will fall
back to REGULAR.  If REGULAR is not supported, it will be disabled.
This means, AUTO is implicitly handled by the dependency solver of
Kconfig, hence removed.

I also turned the 'choice' into only two boolean symbols.  The use of
'choice' is not a good idea here, because all of all{yes,mod,no}config
would choose the first visible value, while we want allnoconfig to
disable as many features as possible.

X86 has additional shell scripts in case the compiler supports those
options, but generates broken code.  I added CC_HAS_SANE_STACKPROTECTOR
to test this.  I had to add -m32 to gcc-x86_32-has-stack-protector.sh
to make it work correctly.

315bab4e97 kbuild: fix endless syncconfig in case arch Makefile sets CROSS_COMPILE
Commit 21c54b7747 ("kconfig: show compiler version text in the top
comment") was intended to detect the compiler upgrade, but Geert
reported a breakage on the m68k build.

The compiler upgrade is detected by the change of the environment
variable, CC_VERSION_TEXT, which contains the first line of the output
from $(CC) --version.  Currently, this works well when CROSS_COMPILE
is given via the environment variable or the Make command line.

However, some architectures such as m68k can specify CROSS_COMPILE
from arch/$(SRCARCH)/Makefile as well.  In this case, "make ARCH=m68k"
ends up with endless syncconfig loop.

  $ make ARCH=m68k defconfig
  *** Default configuration is based on 'multi_defconfig'
  #
  # configuration written to .config
  #
  $ make ARCH=m68k
  scripts/kconfig/conf  --syncconfig Kconfig
  scripts/kconfig/conf  --syncconfig Kconfig
  scripts/kconfig/conf  --syncconfig Kconfig
  scripts/kconfig/conf  --syncconfig Kconfig

Things are happening like this:

Because arch/$(SRCARCH)/Makefile is included after CC_VERSION_TEXT
is set, it contains the host compiler version in the defconfig phase.

To create or update auto.conf, the following line is triggered:

include/config/%.conf: $(KCONFIG_CONFIG) include/config/auto.conf.cmd
        $(Q)$(MAKE) -f $(srctree)/Makefile syncconfig

This recurses the top Makefile after arch/$(SRCARCH)/Makefile is
included.  CROSS_COMPILE is set to a m68k toolchain prefix and
exported to the recursed Make.  Then, syncconfig is invoked with
the target compiler version in CC_VERSION_TEXT.

The Make will restart because auto.conf and auto.conf.cmd have been
updated.  At this point, CROSS_COMPILE is reset, so CC_VERSION_TEXT
is set to the host compiler version again.  Then, syncconfig is
triggered due to the change of CC_VERSION_TEXT.  This loop continues
eternally.

To fix this problem, $(CC_VERSION_TEXT) must be evaluated only after
arch/$(SRCARCH)/Makefile.  Setting it earlier is OK as long as it is
defined by using the '=' operator instead of ':='.

For the defconfig phase, $(CC_VERSION_TEXT) is evaluated when Kbuild
descends into scripts/kconfig/, so it contains the target compiler
version correctly.

include/config/auto.conf.cmd references $(CC_VERSION_TEXT) as well,
so it must be included after arch/$(SRCARCH)/Makefile.

c90fca951e powerpc updates for 4.18
Notable changes:
 
  - Support for split PMD page table lock on 64-bit Book3S (Power8/9).
 
  - Add support for HAVE_RELIABLE_STACKTRACE, so we properly support live
    patching again.
 
  - Add support for patching barrier_nospec in copy_from_user() and syscall entry.
 
  - A couple of fixes for our data breakpoints on Book3S.
 
  - A series from Nick optimising TLB/mm handling with the Radix MMU.
 
  - Numerous small cleanups to squash sparse/gcc warnings from Mathieu Malaterre.
 
  - Several series optimising various parts of the 32-bit code from Christophe Leroy.
 
  - Removal of support for two old machines, "SBC834xE" and "C2K" ("GEFanuc,C2K"),
    which is why the diffstat has so many deletions.
 
 And many other small improvements & fixes.
 
 There's a few out-of-area changes. Some minor ftrace changes OK'ed by Steve, and
 a fix to our powernv cpuidle driver. Then there's a series touching mm, x86 and
 fs/proc/task_mmu.c, which cleans up some details around pkey support. It was
 ack'ed/reviewed by Ingo & Dave and has been in next for several weeks.

Pull overflow updates from Kees Cook:
 "This adds the new overflow checking helpers and adds them to the
  2-factor argument allocators. And this adds the saturating size
  helpers and does a treewide replacement for the struct_size() usage.
  Additionally this adds the overflow testing modules to make sure
  everything works.

  I'm still working on the treewide replacements for allocators with
  "simple" multiplied arguments:

     *alloc(a * b, ...) -> *alloc_array(a, b, ...)

  and

     *zalloc(a * b, ...) -> *calloc(a, b, ...)

  as well as the more complex cases, but that's separable from this
  portion of the series. I expect to have the rest sent before -rc1
  closes; there are a lot of messy cases to clean up.

Merge tag 'audit-pr-20180605' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit

Pull audit updates from Paul Moore:
 "Another reasonable chunk of audit changes for v4.18, thirteen patches
  in total.

  The thirteen patches can mostly be broken down into one of four
  categories: general bug fixes, accessor functions for audit state
  stored in the task_struct, negative filter matches on executable
  names, and extending the (relatively) new seccomp logging knobs to the
  audit subsystem.

  The main driver for the accessor functions from Richard are the
  changes we're working on to associate audit events with containers,
  but I think they have some standalone value too so I figured it would
  be good to get them in now.

  The seccomp/audit patches from Tyler apply the seccomp logging
  improvements from a few releases ago to audit's seccomp logging;
  starting with this patchset the changes in
  /proc/sys/kernel/seccomp/actions_logged should apply to both the
  standard kernel logging and audit.

  As usual, everything passes the audit-testsuite and it happens to
  merge cleanly with your tree"

0eb0061381 It's been a busy release for the IPMI driver. Some notable changes:
A user was running into timeout issues doing maintenance commands over
 the IPMB network behind an IPMI controller.  Extend the maintenance
 mode concept to messages over IPMB and allow the timeouts to be tuned.
 
 Lots of cleanup, style fixing, some bugfixes, and such.
 
 At least one user was having trouble with the way the IPMI driver would
 lock the i2c driver module it used.  The IPMI driver was not designed
 for hotplug.  However, hotplug is a reality now, so the IPMI driver
 was modified to support hotplug.
 
 The proc interface code is now completely removed.  Long live sysfs!

ca95bf62fc linux-kselftest-4.18-rc1
This Kselftest update for 4.18-rc1 consists of:
 
 - Work to restructure timers test suite to move PIE out of rtctest from
   Alexandre Belloni.
 
 - Several minor spelling and bug fixes.
 
 - New cgroup tests from Roman Gushchin and Mike Rapoport.
 
 - Kselftest framework changes to handle and report skipped tests correctly.
   Prior to these changes, framework treated all non-zero return codes from

   to unmet dependencies and/or unsupported configuration, reporting them as
   failed lead to false negatives on the tests that couldn't be run.
 
 - Fixes to test Makefiles to remove unnecessary RUN_TESTS and EMIT_TESTS

0ad39cb3d7 Kconfig updates for v4.18
Kconfig now supports new functionality to perform textual substitution.
 It has been a while since Linus suggested to move compiler option tests
 from makefiles to Kconfig. Finally, here it is. The implementation has
 been generalized into a Make-like macro language. Some built-in functions
 such as 'shell' are provided. Variables and user-defined functions are
 also supported so that 'cc-option', 'ld-option', etc. are implemented as
 macros.
 
 Summary:
 
 - refactor package checks for building {m,n,q,g}conf
 
 - remove unused/unmaintained localization support
 
 - remove Kbuild cache
 
 - drop CONFIG_CROSS_COMPILE support
 
 - replace 'option env=' with direct variable expansion
 
 - add built-in functions such as 'shell'
 
 - support variables and user-defined functions
 
 - add helper macros as as 'cc-option'
 
 - add unit tests and a document of the new macro language
 
 - add 'testconfig' to help
 
 - fix warnings from GCC 8.1

acafe7e302 treewide: Use struct_size() for kmalloc()-family
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
    int stuff;
    void *entry[];
};

instance = kmalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = kmalloc(struct_size(instance, entry, count), GFP_KERNEL);

This patch makes the changes for kmalloc()-family (and kvmalloc()-family)
uses. It was done via automatic conversion with manual review for the
"CHECKME" non-standard cases noted below, using the following Coccinelle
script:

// pkey_cache = kmalloc(sizeof *pkey_cache + tprops->pkey_tbl_len *
//                      sizeof *pkey_cache->table, GFP_KERNEL);

7170e6045a strparser: Add __strp_unpause and use it in ktls.
strp_unpause queues strp_work in order to parse any messages that
arrived while the strparser was paused. However, the process invoking
strp_unpause could eagerly parse a buffered message itself if it held
the sock lock.

__strp_unpause is an alternative to strp_pause that avoids the scheduling
overhead that results when a receiving thread unpauses the strparser
and waits for the next message to be delivered by the workqueue thread.

This patch more than doubled the IOPS achieved in a benchmark of NBD
traffic encrypted using ktls.

fb1967a69f rxrpc: Fix terminal retransmission connection ID to include the channel
When retransmitting the final ACK or ABORT packet for a call, the cid field
in the packet header is set to the connection's cid, but this is incorrect
as it also needs to include the channel number on that connection that the
call was made on.

Fix this by OR'ing in the channel number.

Note that this fixes the bug that:

	commit 1a025028d4
	rxrpc: Fix handling of call quietly cancelled out on server

works around.  I'm not intending to revert that as it will help protect
against problems that might occur on the server.

5040cc990c net: dsa: b53: Fix for brcm tag issue in Cygnus SoC
In the Broadcom Cygnus SoC, the brcm tag needs to be inserted
in between the mac address and the ether type (should use
'DSA_PROTO_TAG_BRCM') for the packets sent to the internal
b53 switch.

Since the Cygnus was added with the BCM58XX device id and the
BCM58XX uses 'DSA_PROTO_TAG_BRCM_PREPEND', the data path is
broken, due to the incorrect brcm tag location.

Add a new b53 device id (BCM583XX) for Cygnus family to fix the
issue. Add the new device id to the BCM58XX family as Cygnus
is similar to the BCM58XX in most other functionalities.

Fixes: 1160603960 ("net: dsa: b53: Support prepended Broadcom tags")

4016a7f15e enic: fix UDP rss bits
In commit 48398b6e70 ("enic: set UDP rss flag") driver needed to set a
single bit to enable UDP rss. This is changed to two bit. One for UDP
IPv4 and other bit for UDP IPv6. The hardware which supports this is not
released yet. When released, driver should set 2 bit to enable UDP rss for
both IPv4 and IPv6.

Also add spinlock around vnic_dev_capable_rss_hash_type().

ff5bc793e4 powerpc/64s/radix: Fix missing ptesync in flush_cache_vmap
There is a typo in f1cb8f9beb ("powerpc/64s/radix: avoid ptesync after
set_pte and ptep_set_access_flags") config ifdef, which results in the
necessary ptesync not being issued after vmalloc.

This causes random kernel faults in module load, bpf load, anywhere
that vmalloc mappings are used.

After correcting the code, this survives a guest kernel booting
hundreds of times where previously there would be a crash every few
boots (I haven't noticed the crash on host, perhaps due to different
TLB and page table walking behaviour in hardware).

A memory clobber is also added to the flush, just to be sure it won't
be reordered with the pte set or the subsequent mapping access.

Pull cgroup updates from Tejun Heo:

 - For cpustat, cgroup has a percpu hierarchical stat mechanism which
   propagates up the hierarchy lazily.

   This contains commits to factor out and generalize the mechanism so
   that it can be used for other cgroup stats too.

   The original intention was to update memcg stats to use it but memcg
   went for a different approach, so still the only user is cpustat. The
   factoring out and generalization still make sense and it's likely
   that this can be used for other purposes in the future.

 - cgroup uses kernfs_notify() (which uses fsnotify()) to inform user
   space of certain events. A rate limiting mechanism is added.

Pull driver core updates from Greg KH:
 "Here is the driver core patchset for 4.18-rc1.

  The large chunk of these are firmware core documentation and api
  updates. Nothing major there, just better descriptions for others to
  be able to understand the firmware code better. There's also a user
  for a new firmware api call.

  Other than that, there are some minor updates for debugfs, kernfs, and
  the driver core itself.

  All of these have been in linux-next for a while with no reported
  issues"
