Driver core patches for 5.8-rc1
Here is the set of driver core patches for 5.8-rc1.
Not all that huge this release, just a number of small fixes and
updates:
- software node fixes
- kobject now sends KOBJ_REMOVE when it is removed from sysfs,
not when it is removed from memory (which could come much
later)
- device link additions and fixes based on testing on more
devices
- firmware core cleanups
- other minor changes, full details in the shortlog
All have been in linux-next for a while with no reported issues.

Kbuild updates for v5.8
- fix warnings in 'make clean' for ARCH=um, hexagon, h8300, unicore32
- ensure to rebuild all objects when the compiler is upgraded
- exclude system headers from dependency tracking and fixdep processing
- fix potential bit-size mismatch between the kernel and BPF user-mode
helper
- add the new syntax 'userprogs' to build user-space programs for the
target architecture (the same arch as the kernel)
- compile user-space sample code under samples/ for the target arch
instead of the host arch
- make headers_install fail if a CONFIG option is leaked to user-space
- sanitize the output format of scripts/checkstack.pl
- handle ARM 'push' instruction in scripts/checkstack.pl
- error out before modpost if a module name conflict is found
- error out when multiple directories are passed to M= because this
feature is broken for a long time
- add CONFIG_DEBUG_INFO_COMPRESSED to support compressed debug info
- a lot of cleanups of modpost
- dump vmlinux symbols out into vmlinux.symvers, and reuse it in the
second pass of modpost
- do not run the second pass of modpost if nothing in modules is updated
- install modules.builtin(.modinfo) by 'make install' as well as by
'make modules_install' because it is useful even when CONFIG_MODULES=n
- add new command line variables, GZIP, BZIP2, LZOP, LZMA, LZ4, and XZ
to allow users to use alternatives such as pigz, pbzip2, etc.

firmware/dmi: Report DMI Bios & EC firmware release
Some vendors like HPe or Dell, encode the release version of their BIOS
in the "System BIOS {Major|Minor} Release" fields of Type 0.
This information is used to know which bios release actually runs.
It could be used for some quirks, debugging sessions or inventory tasks.
A typical output for a Dell system running the 65.27 bios is :
[root@t1700 ~]# cat /sys/devices/virtual/dmi/id/bios_release
65.27
[root@t1700 ~]#
Servers that have a BMC encode the release version of their firmware in the
"Embedded Controller Firmware {Major|Minor} Release" fields of Type 0.
This information is used to know which BMC release actually runs.
It could be used for some quirks, debugging sessions or inventory tasks.
A typical output for a Dell system running the 3.75 bmc release is :

"There's some core VFS changes which affect a couple of filesystems:
- Make the inode hash table RCU safe and providing some RCU-safe
accessor functions. The search can then be done without taking the
inode_hash_lock. Care must be taken because the object may be being
deleted and no wait is made.
- Allow iunique() to avoid taking the inode_hash_lock.
- Allow AFS's callback processing to avoid taking the inode_hash_lock
when using the inode table to find an inode to notify.
- Improve Ext4's time updating. Konstantin Khlebnikov said "For now,
I've plugged this issue with try-lock in ext4 lazy time update.
This solution is much better."
Then there's a set of changes to make a number of improvements to the
AFS driver:
- Improve callback (ie. third party change notification) processing
by:
(a) Relying more on the fact we're doing this under RCU and by
using fewer locks. This makes use of the RCU-based inode
searching outlined above.
(b) Moving to keeping volumes in a tree indexed by volume ID
rather than a flat list.
(c) Making the server and volume records logically part of the
cell. This means that a server record now points directly at
the cell and the tree of volumes is there. This removes an N:M
mapping table, simplifying things.
- Improve keeping NAT or firewall channels open for the server
callbacks to reach the client by actively polling the fileserver on
a timed basis, instead of only doing it when we have an operation
to process.
- Improving detection of delayed or lost callbacks by including the
parent directory in the list of file IDs to be queried when doing a
bulk status fetch from lookup. We can then check to see if our copy
of the directory has changed under us without us getting notified.
- Determine aliasing of cells (such as a cell that is pointed to be a
DNS alias). This allows us to avoid having ambiguity due to
apparently different cells using the same volume and file servers.
- Improve the fileserver rotation to do more probing when it detects
that all of the addresses to a server are listed as non-responsive.
It's possible that an address that previously stopped responding
has become responsive again.
Beyond that, lay some foundations for making some calls asynchronous:
- Turn the fileserver cursor struct into a general operation struct
and hang the parameters off of that rather than keeping them in
local variables and hang results off of that rather than the call
struct.
- Implement some general operation handling code and simplify the
callers of operations that affect a volume or a volume component
(such as a file). Most of the operation is now done by core code.
- Operations are supplied with a table of operations to issue
different variants of RPCs and to manage the completion, where all
the required data is held in the operation object, thereby allowing
these to be called from a workqueue.
- Put the standard "if (begin), while(select), call op, end" sequence
into a canned function that just emulates the current behaviour for
now.
There are also some fixes interspersed:
- Don't let the EACCES from ICMP6 mapping reach the user as such,
since it's confusing as to whether it's a filesystem error. Convert
it to EHOSTUNREACH.
- Don't use the epoch value acquired through probing a server. If we
have two servers with the same UUID but in different cells, it's
hard to draw conclusions from them having different epoch values.
- Don't interpret the argument to the CB.ProbeUuid RPC as a
fileserver UUID and look up a fileserver from it.
- Deal with servers in different cells having the same UUIDs. In the
event that a CB.InitCallBackState3 RPC is received, we have to
break the callback promises for every server record matching that
UUID.
- Don't let afs_statfs return values that go below 0.
- Don't use running fileserver probe state to make server selection
and address selection decisions on. Only make decisions on final
state as the running state is cleared at the start of probing"

- Largest change for this cycle is the DM zoned target's metadata
version 2 feature that adds support for pairing regular block devices with a zoned device to ease performance impact associated with finite random zones of zoned device. Changes came in 3 batches: first prepared for and then added the ability to pair a single regular block device, second was a batch of fixes to improve zoned's reclaim heuristic, third removed the limitation of only adding a single additional regular block device to allow many devices. Testing has shown linear scaling as more devices are added. - Add new emulated block size (ebs) target that emulates a smaller logical_block_size than a block device supports. Primary use-case is to emulate "512e" devices that have 512 byte logical_block_size and 4KB physical_block_size. This is useful to some legacy applications otherwise wouldn't be ablee to be used on 4K devices because they depend on issuing IO in 512 byte granularity. - Add discard interfaces to DM bufio. First consumer of the interface is the dm-ebs target that makes heavy use of dm-bufio. - Fix DM crypt's block queue_limits stacking to not truncate logic_block_size. - Add Documentation for DM integrity's status line. - Switch DMDEBUG from a compile time config option to instead use dynamic debug via pr_debug. - Fix DM multipath target's hueristic for how it manages "queue_if_no_path" state internally. DM multipath now avoids disabling "queue_if_no_path" unless it is actually needed (e.g. in response to configure timeout or explicit "fail_if_no_path" message). This fixes reports of spurious -EIO being reported back to userspace application during fault tolerance testing with an NVMe backend. Added various dynamic DMDEBUG messages to assist with debugging queue_if_no_path in the future. - Add a new DM multipath "Historical Service Time" Path Selector. - Fix DM multipath's dm_blk_ioctl() to switch paths on IO error. - Improve DM writecache target performance by using explicit cache flushing for target's single-threaded usecase and a small cleanup to remove unnecessary test in persistent_memory_claim. - Other small cleanups in DM core, dm-persistent-data, and DM integrity. -----BEGIN PGP SIGNATURE----- iQFHBAABCAAxFiEEJfWUX4UqZ4x1O2wixSPxCi2dA1oFAl7alrgTHHNuaXR6ZXJA cmVkaGF0LmNvbQAKCRDFI/EKLZ0DWl42B/9sBd+j60emy4Bliu/f3pd7SEkFrSXv K2jXicRFx4E5kO0aLK+fX65cOiq2vvLsDh8c++0TLXcD9q7oK0qxK9c8TCPq29Cx W2J2dwdjyyqqbr3/FZHYYM9KLOl5rsxJLygXwhJhQ2Gny44L7nVACrAXNzXIHJ3r f8xr+GLdF/jz7WLj8bwEDo3Bf8wvxDvl2ijqj7EceOhTutNE8xHQ6UcTPqTtozJy sNM8UQNk1L43DBAvXfrKZ+yQ5DYAKdXKJpV9C8qv5DEGbaEikuMrHddgO4KlDdp4 VjPk9GSfPwGcJ4ecN8vgecZVGvh52ZU7OZ8qey/q0zqps74jeHTZQQyM =jRun -----END PGP SIGNATURE----- Merge tag 'for-5.8/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - The largest change for this cycle is the DM zoned target's metadata version 2 feature that adds support for pairing regular block devices with a zoned device to ease the performance impact associated with finite random zones of zoned device.

This is the bulk of GPIO changes for the v5.8 kernel cycle.
Core changes:
- A new GPIO aggregator driver has been merged: this can
join a few select GPIO lines into a new aggregated GPIO
chip. This can be used for security: a process can be
granted access to only these lines, for example for
industrial control. Another way to use this is to
reexpose certain select lines to a virtual machine or
container.
- Warn if the gpio-line-names is too long in he DT parser
core.
- GPIO lines can now be looked up by line name in addition
to being looked up by offset.
New drivers:
- A new generic regmap GPIO driver has been merged. Too
many regmap drivers are starting to look like each other
so we need to create some common ground and try to move
drivers over to using that.
- The F7188X driver now supports F81865.
Driver improvements:
- Large improvements to the PCA953x expander, get multiple lines
and several cleanups.
- Large improvements to the DesignWare DWAPB driver, and Sergey
Semin has volunteered to maintain it.
- PL061 can now be built as a module, this is part of a bigger
effort to make the ARM platforms more modular.

powerpc updates for 5.8
- Support for userspace to send requests directly to the on-chip GZIP
accelerator on Power9.
- Rework of our lockless page table walking (__find_linux_pte()) to make it
safe against parallel page table manipulations without relying on an IPI for
serialisation.
- A series of fixes & enhancements to make our machine check handling more
robust.
- Lots of plumbing to add support for "prefixed" (64-bit) instructions on
Power10.
- Support for using huge pages for the linear mapping on 8xx (32-bit).
- Remove obsolete Xilinx PPC405/PPC440 support, and an associated sound driver.
- Removal of some obsolete 40x platforms and associated cruft.
- Initial support for booting on Power10.
- Lots of other small features, cleanups & fixes.

ARM/SoC: drivers for v5.7
These are updates to SoC specific drivers that did not have
another subsystem maintainer tree to go through for some
reason:
- Some bus and memory drivers for the MIPS P5600 based
Baikal-T1 SoC that is getting added through the MIPS tree.
- There are new soc_device identification drivers for TI K3,
Qualcomm MSM8939
- New reset controller drivers for NXP i.MX8MP, Renesas
RZ/G1H, and Hisilicon hi6220
- The SCMI firmware interface can now work across ARM SMC/HVC
as a transport.
- Mediatek platforms now use a new driver for their "MMSYS"
hardware block that controls clocks and some other aspects
in behalf of the media and gpu drivers.
- Some Tegra processors have improved power management
support, including getting woken up by the PMIC and cluster
power down during idle.
- A new v4l staging driver for Tegra is added.
- Cleanups and minor bugfixes for TI, NXP, Hisilicon,
Mediatek, and Tegra.

ARM: SoC changes for v5.8
One new platform gets added, the Realtek RTD1195, which is an older Cortex-a7 based relative of the RTD12xx chips that are already supported in arch/arm64. The platform may also be extended to support running 32-bit kernels on those 64-bit chips for memory-constrained machines. In the Renesas shmobile platform, we gain support for "RZ/G1H" or R8A7742, an eight-core chip based on Cortex-A15 and Cortex-A7 cores, originally released in 2016 as one of the last high-end 32-bit designs. There is ongoing cleanup for the integrator, tegra, imx, and omap2 platforms, with integrator getting very close to the goal of having zero code in arch/arm/, and omap2 moving more of the chip specifics from old board code into device tree files. The Versatile Express platform is made more modular, with built-in drivers now becoming loadable modules. This is part of a greater effort for the Android OS to have a common kernel binary for all platforms and any platform specific code in loadable modules. The PXA platform drops support for Compulab's pxa2xx boards that had rather unusual flash and PCI drivers but no known users remaining. All device drivers specific to those boards can now get removed as well. Across platforms, there is ongoing cleanup, with Geert and Rob revisiting some a lot of Kconfig options.

elfnote: mark all .note sections SHF_ALLOC
ELFNOTE_START allows callers to specify flags for .pushsection assembler
directives. All callsites but ELF_NOTE use "a" for SHF_ALLOC. For vdso's
that explicitly use ELF_NOTE_START and BUILD_SALT, the same section is
specified twice after preprocessing, once with "a" flag, once without.
Example:
.pushsection .note.Linux, "a", @note ;
.pushsection .note.Linux, "", @note ;
While GNU as allows this ordering, it warns for the opposite ordering,
making these directives position dependent. We'd prefer not to precisely
match this behavior in Clang's integrated assembler. Instead, the non
__ASSEMBLY__ definition of ELF_NOTE uses
__attribute__((section(".note.Linux"))) which is created with SHF_ALLOC,
so let's make the __ASSEMBLY__ definition of ELF_NOTE consistent with C
and just always use "a" flag.
This allows Clang to assemble a working mainline (5.6) kernel via:
$ make CC=clang AS=clang

include/linux/bitops.h: avoid clang shift-count-overflow warnings
Clang normally does not warn about certain issues in inline functions when

on 32-bit targets:

mm: replace zero-length array with flexible-array member
The current codebase makes use of the zero-length array language extension
to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning in
case the flexible array does not occur last in the structure, which will
help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by this
change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

mm/memory_hotplug: introduce add_memory_driver_managed()
Patch series "mm/memory_hotplug: Interface to add driver-managed system
ram", v4.
kexec (via kexec_load()) can currently not properly handle memory added
via dax/kmem, and will have similar issues with virtio-mem. kexec-tools
will currently add all memory to the fixed-up initial firmware memmap. In
case of dax/kmem, this means that - in contrast to a proper reboot - how
that persistent memory will be used can no longer be configured by the
kexec'd kernel. In case of virtio-mem it will be harmful, because that
memory might contain inaccessible pieces that require coordination with
hypervisor first.
In both cases, we want to let the driver in the kexec'd kernel handle
detecting and adding the memory, like during an ordinary reboot.
Introduce add_memory_driver_managed(). More on the samentics are in patch
#1.
In the future, we might want to make this behavior configurable for
dax/kmem- either by configuring it in the kernel (which would then also
allow to configure kexec_file_load()) or in kexec-tools by also adding
"System RAM (kmem)" memory from /proc/iomem to the fixed-up initial
firmware memmap.
More on the motivation can be found in [1] and [2].
[1] https://lkml.kernel.org/r/20200429160803.109056-1-david@redhat.com
[2] https://lkml.kernel.org/r/20200430102908.10107-1-david@redhat.com
This patch (of 3):
Some device drivers rely on memory they managed to not get added to the
initial (firmware) memmap as system RAM - so it's not used as initial
system RAM by the kernel and the driver is under control. While this is
the case during cold boot and after a reboot, kexec is not aware of that
and might add such memory to the initial (firmware) memmap of the kexec
kernel. We need ways to teach kernel and userspace that this system ram
is different.
For example, dax/kmem allows to decide at runtime if persistent memory is
to be used as system ram. Another future user is virtio-mem, which has to
coordinate with its hypervisor to deal with inaccessible parts within
memory resources.
We want to let users in the kernel (esp. kexec) but also user space
(esp. kexec-tools) know that this memory has different semantics and
needs to be handled differently:
1. Don't create entries in /sys/firmware/memmap/
2. Name the memory resource "System RAM ($DRIVER)" (exposed via
/proc/iomem) ($DRIVER might be "kmem", "virtio_mem").
3. Flag the memory resource IORESOURCE_MEM_DRIVER_MANAGED
/sys/firmware/memmap/ [1] represents the "raw firmware-provided memory
map" because "on most architectures that firmware-provided memory map is
modified afterwards by the kernel itself". The primary user is kexec on
x86-64. Since commit

mm: add kvfree_sensitive() for freeing sensitive data objects
For kvmalloc'ed data object that contains sensitive information like
cryptographic keys, we need to make sure that the buffer is always cleared
before freeing it. Using memset() alone for buffer clearing may not
provide certainty as the compiler may compile it away. To be sure, the
special memzero_explicit() has to be used.
This patch introduces a new kvfree_sensitive() for freeing those sensitive
data objects allocated by kvmalloc(). The relevant places where
kvfree_sensitive() can be used are modified to use it.

arch/kmap: define kmap_atomic_prot() for all arch's
To support kmap_atomic_prot(), all architectures need to support protections passed to their kmap_atomic_high() function. Pass protections into kmap_atomic_high() and change the name to kmap_atomic_high_prot() to match. Then define kmap_atomic_prot() as a core function which calls kmap_atomic_high_prot() when needed. Finally, redefine kmap_atomic() as a wrapper of kmap_atomic_prot() with the default kmap_prot exported by the architectures.

arch/kunmap_atomic: consolidate duplicate code
Every single architecture (including !CONFIG_HIGHMEM) calls... pagefault_enable(); preempt_enable(); ... before returning from __kunmap_atomic(). Lift this code into the kunmap_atomic() macro.

arch/kmap_atomic: consolidate duplicate code
Every arch has the same code to ensure atomic operations and a check for !HIGHMEM page. Remove the duplicate code by defining a core kmap_atomic() which only calls the arch specific kmap_atomic_high() when the page is high memory.

arch/kunmap: remove duplicate kunmap implementations
All architectures do exactly the same thing for kunmap(); remove all the duplicate definitions and lift the call to the core.

arch/kmap: remove redundant arch specific kmaps
The kmap code for all the architectures is almost 100% identical. Lift the common code to the core. Use ARCH_HAS_KMAP_FLUSH_TLB to indicate if an arch defines kmap_flush_tlb() and call if if needed. This also has the benefit of changing kmap() on a number of architectures to be an inline call rather than an actual function.
