The font files contain bit masks for characters in the cp437 character
set, and comments showing what character this is supposed to be.
This only makes sense when the terminal used to view the files is set to
the same codepage, but all other files in the kernel now use utf-8
encoding.
This changes those comments to utf-8 as well, for consistency.

The ebcdic.c file contains tables for converting between ebcdic and PC
codepage 437. I could however not identify which encoding was used for
the comments. This seems to be some variation of ISO_8859-1 with
non-UTF-8 escape characters.
I have converted this to UTF-8 by manually removing the escape
characters and then running it through recode, to get the same encoding
that we use for the rest of the kernel.

Ref-> 1c8f422059 ("mm: change return type to vm_fault_t")
Previously vm_insert_{pfn,mixed} returns err which driver mapped into
VM_FAULT_* type. The new function vmf_insert_{pfn,mixed} will replace
this inefficiency by returning VM_FAULT_* type.
vmf_error() is the newly introduce inline function in 4.17-rc6.

A process can be killed with SIGBUS(BUS_MCEERR_AR) when it tries to
allocate a page that was just freed on the way of soft-offline. This is
undesirable because soft-offline (which is about corrected error) is
less aggressive than hard-offline (which is about uncorrected error),
and we can make soft-offline fail and keep using the page for good
reason like "system is busy."
Two main changes of this patch are:
- setting migrate type of the target page to MIGRATE_ISOLATE. As done
in free_unref_page_commit(), this makes kernel bypass pcplist when
freeing the page. So we can assume that the page is in freelist just
after put_page() returns,
- setting PG_hwpoison on free page under zone->lock which protects
freelists, so this allows us to avoid setting PG_hwpoison on a page
that is decided to be allocated soon.

Patch series "mm: soft-offline: fix race against page allocation".
Xishi recently reported the issue about race on reusing the target pages
of soft offlining. Discussion and analysis showed that we need make
sure that setting PG_hwpoison should be done in the right place under
zone->lock for soft offline. 1/2 handles free hugepage's case, and 2/2
hanldes free buddy page's case.
This patch (of 2):
There's a race condition between soft offline and hugetlb_fault which
causes unexpected process killing and/or hugetlb allocation failure.
The process killing is caused by the following flow:
CPU 0 CPU 1 CPU 2
soft offline
get_any_page
// find the hugetlb is free
mmap a hugetlb file
page fault
...
hugetlb_fault
hugetlb_no_page
alloc_huge_page
// succeed
soft_offline_free_page
// set hwpoison flag
mmap the hugetlb file
page fault
...
hugetlb_fault
hugetlb_no_page
find_lock_page
return VM_FAULT_HWPOISON
mm_fault_error
do_sigbus
// kill the process
The hugetlb allocation failure comes from the following flow:
CPU 0 CPU 1
mmap a hugetlb file
// reserve all free page but don't fault-in
soft offline
get_any_page
// find the hugetlb is free
soft_offline_free_page
// set hwpoison flag
dissolve_free_huge_page
// fail because all free hugepages are reserved
page fault
...
hugetlb_fault
hugetlb_no_page
alloc_huge_page
...
dequeue_huge_page_node_exact
// ignore hwpoisoned hugepage
// and finally fail due to no-mem
The root cause of this is that current soft-offline code is written based
on an assumption that PageHWPoison flag should be set at first to avoid
accessing the corrupted data. This makes sense for memory_failure() or
hard offline, but does not for soft offline because soft offline is about
corrected (not uncorrected) error and is safe from data lost. This patch
changes soft offline semantics where it sets PageHWPoison flag only after
containment of the error page completes successfully.

Disallows open of FIFOs or regular files not owned by the user in world
writable sticky directories, unless the owner is the same as that of the
directory or the file is opened without the O_CREAT flag. The purpose
is to make data spoofing attacks harder. This protection can be turned
on and off separately for FIFOs and regular files via sysctl, just like
the symlinks/hardlinks protection. This patch is based on Openwall's
"HARDEN_FIFO" feature by Solar Designer.
This is a brief list of old vulnerabilities that could have been prevented
by this feature, some of them even allow for privilege escalation:
CVE-2000-1134
CVE-2007-3852
CVE-2008-0525
CVE-2009-0416
CVE-2011-4834
CVE-2015-1838
CVE-2015-7442
CVE-2016-7489
This list is not meant to be complete. It's difficult to track down all
vulnerabilities of this kind because they were often reported without any
mention of this particular attack vector. In fact, before
hardlinks/symlinks restrictions, fifos/regular files weren't the favorite
vehicle to exploit them.

An HFS+ filesystem can be mounted read-only without having a metadata
directory, which is needed to support hardlinks. But if the catalog
data is corrupted, a directory lookup may still find dentries claiming
to be hardlinks.
hfsplus_lookup() does check that ->hidden_dir is not NULL in such a
situation, but mistakenly does so after dereferencing it for the first
time. Reorder this check to prevent a crash.
This happens when looking up corrupted catalog data (dentry) on a
filesystem with no metadata directory (this could only ever happen on a
read-only mount). Wen Xu sent the replication steps in detail to the

Kbuild generally uses KBUILD_ prefixed variables for the internally

synchronous copies even if the client requests async.
Features:
- Add support for asynchronous server-side COPY operations
Stable bufixes:
- Fix an off-by-one in bl_map_stripe() (v3.17+)
- NFSv4 client live hangs after live data migration recovery (v4.9+)
- xprtrdma: Fix disconnect regression (v4.18+)
- Fix locking in pnfs_generic_recover_commit_reqs (v4.14+)
- Fix a sleep in atomic context in nfs4_callback_sequence() (v4.9+)
Other bugfixes and cleanups:
- Optimizations and fixes involving NFS v4.1 / pNFS layout handling
- Optimize lseek(fd, SEEK_CUR, 0) on directories to avoid locking
- Immediately reschedule writeback when the server replies with an
error
- Fix excessive attribute revalidation in nfs_execute_ok()
- Add error checking to nfs_idmap_prepare_message()
- Use new vm_fault_t return type
- Return a delegation when reclaiming one that the server has
recalled
- Referrals should inherit proto setting from parents
- Make rpc_auth_create_args a const
- Improvements to rpc_iostats tracking
- Fix a potential reference leak when there is an error processing a
callback
- Fix rmdir / mkdir / rename nlink accounting
- Fix updating inode change attribute
- Fix error handling in nfsn4_sp4_select_mode()
- Use an appropriate work queue for direct-write completion
- Don't busy wait if NFSv4 session draining is interrupted"

Merge fixes for missing TLB shootdowns.
This fixes a couple of cases that involved us possibly freeing page
table structures before the required TLB shootdown had been done.
There are a few cleanup patches to make the code easier to follow, and
to avoid some of the more problematic cases entirely when not necessary.
To make this easier for backports, it undoes the recent lazy TLB
patches, because the cleanups and fixes are more important, and Rik is
ok with re-doing them later when things have calmed down.
The missing TLB flush was only delayed, and the wrong ordering only
happened under memory pressure (and in theory under a couple of other
fairly theoretical situations), so this may have been all very unlikely
to have hit people in practice.
But getting the TLB shootdown wrong is _so_ hard to debug and see that I
consider this a crticial fix.
Many thanks to Jann Horn for having debugged this.

- Fix microMIPS build failures by adding a .insn directive to the
barrier_before_unreachable() asm statement in order to convince the
toolchain that the asm statement is a valid branch target rather
than a bogus attempt to switch ISA.
- Clean up our declarations of TLB functions that we overwrite with
generated code in order to prevent the compiler making assumptions
about alignment that cause microMIPS kernels built with GCC 7 &
above to die early during boot.
- Fix up a regression for MIPS32 kernels which slipped into the main

Merge tag 'mips_4.19_2' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux
Pull MIPS fixes from Paul Burton:
- Fix microMIPS build failures by adding a .insn directive to the
barrier_before_unreachable() asm statement in order to convince the
toolchain that the asm statement is a valid branch target rather
than a bogus attempt to switch ISA.
- Clean up our declarations of TLB functions that we overwrite with
generated code in order to prevent the compiler making assumptions
about alignment that cause microMIPS kernels built with GCC 7 &
above to die early during boot.
- Fix up a regression for MIPS32 kernels which slipped into the main
MIPS pull for 4.19, causing CONFIG_32BIT=y kernels to contain
inappropriate MIPS64 instructions.
- Extend our existing workaround for MIPSr6 builds that end up using
the __multi3 intrinsic to GCC 7 & below, rather than just GCC 7.
* tag 'mips_4.19_2' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux:
MIPS: lib: Provide MIPS64r6 __multi3() for GCC < 7
MIPS: Workaround GCC __builtin_unreachable reordering bug
compiler.h: Allow arch-specific asm/compiler.h
MIPS: Avoid move psuedo-instruction whilst using MIPS_ISA_LEVEL

Business as usual -- the bulk of our changes are to devicetree files
with new hardware support, new SoCs and platforms, and new board types.
New SoCs/platforms:
- Raspberry Pi Compute Module (CM1) and IO board
- i.MX6SSL from NXP
- Renesas RZ/N1D SoC (R9A06G032), Dual Cortex-A7 with Ethernet, CAN and
PLC interfaces
- TI AM654 SoC, Quad Cortex-A53, safety subsystem with Cortex-R5
controllers, communication and PRU subsystem and lots of other
interfaces (PCIe, USB3, etc).
New boards and systems:
- Several Atmel at91-based boards from Laird
- Marvell Armada388-based Helios4 board from SolidRun
- Samsung Aires-based phones (s5pv210)
- Allwinner A64-based Pinebook laptop
In addition to the above, there's the usual amount of new devices
described on existing platforms, fixes and tweaks and new minor variants
of boards/platforms.

This tag contains a pair of fixes to the RISC-V port. I've based this
on top of the merge of my previous PR, as I wanted to keep this as
linear as possible (so I didn't want to base on the last tag, which is
4.18 as I'm signing this PR) but didn't want to just grab master at some
arbitrary point. Let me know if that's the wrong thing to do.
The fixes are:
* The removal of our compat.h, which didn't do anything.
* Fixes to sys_riscv_flush_icache to ensure it actually shows up. We're
going to just call this a bug in the ABI, as it was always supposed to
be there.
I've given these a simple build+boot test, both individually and as the
actual tag.

from being traced by kprobes. During my testing, I found that there's places
that we may want to add kprobes to notrace, thus we may end up changing this
code before 4.19 is released. The history behind this change is that we
found that adding kprobes to various notrace functions caused the kernel to
crashed. We took the safe route and decided not to allow kprobes to trace
any notrace function. But because notrace is added to functions that just
cause weird side effects to the function tracer, but are still safe,
preventing kprobes for all notrace functios may be too much of a big hammer.
One such place is __schedule() is marked notrace, to keep function tracer
from doing strange recursive loops when it gets traced with NEED_RESCHED
set. With this change, one can not add kprobes to the scheduler.
Masami also added code to use gcov on ftrace.

Merge tag 'trace-v4.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing fixes from Steven Rostedt:
"Masami found an off by one bug in the code that keeps "notrace"
functions from being traced by kprobes. During my testing, I found
that there's places that we may want to add kprobes to notrace, thus
we may end up changing this code before 4.19 is released.
The history behind this change is that we found that adding kprobes to
various notrace functions caused the kernel to crashed. We took the
safe route and decided not to allow kprobes to trace any notrace
function.
But because notrace is added to functions that just cause weird side
effects to the function tracer, but are still safe, preventing kprobes
for all notrace functios may be too much of a big hammer.
One such place is __schedule() is marked notrace, to keep function
tracer from doing strange recursive loops when it gets traced with
NEED_RESCHED set. With this change, one can not add kprobes to the
scheduler.
Masami also added code to use gcov on ftrace"
* tag 'trace-v4.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
tracing/kprobes: Fix to check notrace function with correct range
tracing: Allow gcov profiling on only ftrace subsystem
If we don't use paravirt; don't play unnecessary and complicated games
to free page-tables.

The generic tlb_end_vma does not call invalidate_range mmu notifier, and
it resets resets the mmu_gather range, which means the notifier won't be
called on part of the range in case of an unmap that spans multiple
vmas.
ARM64 seems to be the only arch I could see that has notifiers and uses
the generic tlb_end_vma. I have not actually tested it.
[ Catalin and Will point out that ARM64 currently only uses the
notifiers for KVM, which doesn't use the ->invalidate_range()
callback right now, so it's a bug, but one that happens to
not affect them. So not necessary for stable. - Linus ]

Jann reported that x86 was missing required TLB invalidates when he
hit the !*batch slow path in tlb_remove_table().
This is indeed the case; RCU_TABLE_FREE does not provide TLB (cache)
invalidates, the PowerPC-hash where this code originated and the
Sparc-hash where this was subsequently used did not need that. ARM
which later used this put an explicit TLB invalidate in their
__p*_free_tlb() functions, and PowerPC-radix followed that example.
But when we hooked up x86 we failed to consider this. Fix this by
(optionally) hooking tlb_remove_table() into the TLB invalidate code.
NOTE: s390 was also needing something like this and might now
be able to use the generic code again.
[ Modified to be on top of Nick's cleanups, which simplified this patch
now that tlb_flush_mmu_tlbonly() really only flushes the TLB - Linus ]

Will noted that only checking mm_users is incorrect; we should also
check mm_count in order to cover CPUs that have a lazy reference to
this mm (and could do speculative TLB operations).
If removing this turns out to be a performance issue, we can
re-instate a more complete check, but in tlb_table_flush() eliding the
call_rcu_sched().
