devlink: convert occ_get op to separate registration
This resolves race during initialization where the resources with
ops are registered before driver and the structures used by occ_get
op is initialized. So keep occ_get callbacks registered only when
all structs are initialized.
The example flows, as it is in mlxsw:
1) driver load/asic probe:
mlxsw_core
-> mlxsw_sp_resources_register
-> mlxsw_sp_kvdl_resources_register
-> devlink_resource_register IDX
mlxsw_spectrum
-> mlxsw_sp_kvdl_init
-> mlxsw_sp_kvdl_parts_init
-> mlxsw_sp_kvdl_part_init
-> devlink_resource_size_get IDX (to get the current setup
size from devlink)
-> devlink_resource_occ_get_register IDX (register current
occupancy getter)
2) reload triggered by devlink command:
-> mlxsw_devlink_core_bus_device_reload
-> mlxsw_sp_fini
-> mlxsw_sp_kvdl_fini
-> devlink_resource_occ_get_unregister IDX
(struct mlxsw_sp *mlxsw_sp is freed at this point, call to occ get
which is using mlxsw_sp would cause use-after free)
-> mlxsw_sp_init
-> mlxsw_sp_kvdl_init
-> mlxsw_sp_kvdl_parts_init
-> mlxsw_sp_kvdl_part_init
-> devlink_resource_size_get IDX (to get the current setup
size from devlink)
-> devlink_resource_occ_get_register IDX (register current
occupancy getter)

Char/Misc patches for 4.17-rc1
Here is the big set of char/misc driver patches for 4.17-rc1.
There are a lot of little things in here, nothing huge, but all
important to the different hardware types involved:
- thunderbolt driver updates
- parport updates (people still care...)
- nvmem driver updates
- mei updates (as always)
- hwtracing driver updates
- hyperv driver updates
- extcon driver updates
- and a handfull of even smaller driver subsystem and individual
driver updates
All of these have been in linux-next with no reported issues.

Driver core patches for 4.17-rc1
Here is the "big" set of driver core patches for 4.17-rc1. There's really not much here, just a bunch of firmware code refactoring from Luis as he attempts to wrangle that codebase into something that is managable, along with a bunch of userspace tests for it.

Staging/IIO patches for 4.17-rc1
Here is the big set of Staging/IIO driver patches for 4.17-rc1. It is a lot, over 500 changes, but not huge by previous kernel release standards. We deleted more lines than we added again (27k added vs. 91k remvoed), thanks to finally being able to delete the IRDA drivers and networking code. We also deleted the ccree crypto driver, but that's coming back in through the crypto tree to you, in a much cleaned-up form. Added this round is at lot of "mt7621" device support, which is for an embedded device that Neil Brown cares about, and of course a handful of new IIO drivers as well. And finally, the fsl-mc core code moved out of the staging tree to the "real" part of the kernel, which is nice to see happen as well.

And the PHY driver updates are merged in here as well as they interacted with the USB drivers in some places.

Pull networking fixes from David Miller:
"This fixes some fallout from the net-next merge the other day, plus
some non-merge-window-related bug fixes:
1) Fix sparse warnings in bcmgenet, systemport, b53, and mt7530
(Florian Fainelli)
2) pptp does a bogus dst_release() on a route we have a single
refcount on, and attached to a socket, which needs that refcount
(Eric Dumazet)
3) UDP connected sockets on ipv6 can race with route update handling,
resulting in a pre-PMTU update route still stuck on the socket and
thus continuing to get ICMPV6_PKT_TOOBIG errors. We end up never
seeing the updated route. (Alexey Kodanev)
4) Missing list initializer(s) in TIPC (Jon Maloy)
5) Connect phy early to prevent crashes in lan78xx driver (Alexander
Graf)
6) Fix build with modular NVMEM (Arnd Bergmann)

Pull time(r) updates from Thomas Gleixner:
"A small set of updates for timers and timekeeping:
- The most interesting change is the consolidation of clock MONOTONIC
and clock BOOTTIME.
Clock MONOTONIC behaves now exactly like clock BOOTTIME and does
not longer ignore the time spent in suspend. A new clock
MONOTONIC_ACTIVE is provived which behaves like clock MONOTONIC in
kernels before this change. This allows applications to
programmatically check for the clock MONOTONIC behaviour.
As discussed in the review thread, this has the potential of
breaking user space and we might have to revert this. Knock on wood
that we can avoid that exercise.
- Updates to the NTP mechanism to improve accuracy
- A new kernel internal data structure to aid the ongoing Y2038 work.
- Cleanups and simplifications of the clocksource code.

"There are a several user visible changes, the rest is mostly invisible
and continues to clean up the whole code base.
User visible changes:
- new mount option nossd_spread (pair for ssd_spread)
- mount option subvolid will detect junk after the number and fail
the mount
- add message after cancelled device replace
- direct module dependency on libcrc32, removed own crc wrappers
- removed user space transaction ioctls
- use lighter locking when reading /proc/self/mounts, RCU instead of
mutex to avoid unnecessary contention
Enhancements:
- skip writeback of last page when truncating file to same size
- send: do not issue unnecessary truncate operations
- mount option token specifiers: use %u for unsigned values, more
validation
- selftests: more tree block validations
qgroups:
- preparatory work for splitting reservation types for data and
metadata, this should allow for more accurate tracking and fix some
issues with underflows or do further enhancements
- split metadata reservations for started and joined transaction so
they do not get mixed up and are accounted correctly at commit time
- with the above, it's possible to revert patch that potentially
deadlocks when trying to make more space by explicitly committing
when the quota limit is hit
- fix root item corruption when multiple same source snapshots are
created with quota enabled
RAID56:
- make sure target is identical to source when raid56 rebuild fails
after dev-replace
- faster rebuild during scrub, batch by stripes and not
block-by-block
- make more use of cached data when rebuilding from a missing device
Fixes:
- null pointer deref when device replace target is missing
- fix fsync after hole punching when using no-holes feature
- fix lockdep splat when allocating percpu data with wrong GFP flags
Cleanups, refactoring, core changes:
- drop redunant parameters from various functions
- kill and opencode trivial helpers
- __cold/__exit function annotations
- dead code removal
- continued audit and documentation of memory barriers
- error handling: handle removal from uuid tree
- error handling: remove handling of impossible condtitons
- more debugging or error messages

Merge branch 'userns-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull namespace updates from Eric Biederman: "There was a lot of work this cycle fixing bugs that were discovered after the merge window and getting everything ready where we can reasonably support fully unprivileged fuse. The bug fixes you already have and much of the unprivileged fuse work is coming in via other trees. Still left for fully unprivileged fuse is figuring out how to cleanly handle .set_acl and .get_acl in the legacy case, and properly handling of evm xattrs on unprivileged mounts. Included in the tree is a cleanup from Alexely that replaced a linked list with a statically allocated fix sized array for the pid caches, which simplifies and speeds things up. Then there is are some cleanups and fixes for the ipc namespace. The motivation was that in reviewing other code it was discovered that access ipc objects from different pid namespaces recorded pids in such a way that when asked the wrong pids were returned. In the worst case there has been a measured 30% performance impact for sysvipc semaphores. Other test cases showed no measurable performance impact. Manfred Spraul and Davidlohr Bueso who tend to work on sysvipc performance both gave the nod that this is good enough. Casey Schaufler and James Morris have given their approval to the LSM side of the changes. I simplified the types and the code dealing with sysvipc to pass just kern_ipc_perm for all three types of ipc. Which reduced the header dependencies throughout the kernel and simplified the lsm code. Which let me work on the pid fixes without having to worry about trivial changes causing complete kernel recompiles" * 'userns-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: ipc/shm: Fix pid freeing. ipc/shm: fix up for struct file no longer being available in shm.h ipc/smack: Tidy up from the change in type of the ipc security hooks ipc: Directly call the security hook in ipc_ops.associate ipc/sem: Fix semctl(..., GETPID, ...) between pid namespaces ipc/msg: Fix msgctl(..., IPC_STAT, ...) between pid namespaces ipc/shm: Fix shmctl(..., IPC_STAT, ...) between pid namespaces. ipc/util: Helpers for making the sysvipc operations pid namespace aware ipc: Move IPCMNI from include/ipc.h into ipc/util.h msg: Move struct msg_queue into ipc/msg.c shm: Move struct shmid_kernel into ipc/shm.c sem: Move struct sem and struct sem_array into ipc/sem.c msg/security: Pass kern_ipc_perm not msg_queue into the msg_queue security hooks shm/security: Pass kern_ipc_perm not shmid_kernel into the shm security hooks sem/security: Pass kern_ipc_perm not sem_array into the sem security hooks pidns: simpler allocation of pid_* caches |

Pull ACPI updates from Rafael Wysocki:
"These update the ACPICA code in the kernel to follow upstream revision
20180313 which includes fixes related to the so-called module-level
AML (mostly "if" type of statements outside of any methods) that
should improve the handling of systems that load alternative SSDTs
depending on the current configuration, for example, and event
handling fixes related to disabling and enabling GPEs on system
startup and on suspend/resume.
Moreover, the ACPICA license boilerplate is replaced with SPDX license
IDs which alone reduces the number of lines of ACPICA code in the
kernel quite a bit.
Also added is a new driver for the generic ACPI Time and Alarm Device
(TAD). At the moment it only handles the most basic capabilities of
the TAD, however.
In addition to that the ACPI battery driver is improved to handle
battery thresholds on ThinkPads, among other things, some bugs are
fixed, a new backlight quirk is added and some documentation is
updated.

Merge branch 'syscalls-next' of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/linux
Pull removal of in-kernel calls to syscalls from Dominik Brodowski:
"System calls are interaction points between userspace and the kernel.
Therefore, system call functions such as sys_xyzzy() or
compat_sys_xyzzy() should only be called from userspace via the
syscall table, but not from elsewhere in the kernel.
At least on 64-bit x86, it will likely be a hard requirement from
v4.17 onwards to not call system call functions in the kernel: It is
better to use use a different calling convention for system calls
there, where struct pt_regs is decoded on-the-fly in a syscall wrapper
which then hands processing over to the actual syscall function. This
means that only those parameters which are actually needed for a
specific syscall are passed on during syscall entry, instead of
filling in six CPU registers with random user space content all the
time (which may cause serious trouble down the call chain). Those
x86-specific patches will be pushed through the x86 tree in the near
future.
Moreover, rules on how data may be accessed may differ between kernel
data and user data. This is another reason why calling sys_xyzzy() is
generally a bad idea, and -- at most -- acceptable in arch-specific
code.
This patchset removes all in-kernel calls to syscall functions in the
kernel with the exception of arch/. On top of this, it cleans up the
three places where many syscalls are referenced or prototyped, namely
kernel/sys_ni.c, include/linux/syscalls.h and include/linux/compat.h"

arch: remove obsolete architecture ports
This removes the entire architecture code for blackfin, cris, frv, m32r, metag, mn10300, score, and tile, including the associated device drivers. I have been working with the (former) maintainers for each one to ensure that my interpretation was right and the code is definitely unused in mainline kernels. Many had fond memories of working on the respective ports to start with and getting them included in upstream, but also saw no point in keeping the port alive without any users. In the end, it seems that while the eight architectures are extremely different, they all suffered the same fate: There was one company in charge of an SoC line, a CPU microarchitecture and a software ecosystem, which was more costly than licensing newer off-the-shelf CPU cores from a third party (typically ARM, MIPS, or RISC-V). It seems that all the SoC product lines are still around, but have not used the custom CPU architectures for several years at this point. In contrast, CPU instruction sets that remain popular and have actively maintained kernel ports tend to all be used across multiple licensees. The removal came out of a discussion that is now documented at https://lwn.net/Articles/748074/. Unlike the original plans, I'm not marking any ports as deprecated but remove them all at once after I made sure that they are all unused. Some architectures (notably tile, mn10300, and blackfin) are still being shipped in products with old kernels, but those products will never be updated to newer kernel releases. After this series, we still have a few architectures without mainline gcc support: - unicore32 and hexagon both have very outdated gcc releases, but the maintainers promised to work on providing something newer. At least in case of hexagon, this will only be llvm, not gcc. - openrisc, risc-v and nds32 are still in the process of finishing their support or getting it added to mainline gcc in the first place. They all have patched gcc-7.3 ports that work to some degree, but complete upstream support won't happen before gcc-8.1. Csky posted their first kernel patch set last week, their situation will be similar. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJawdL2AAoJEGCrR//JCVInuH0P/RJAZh1nTD+TR34ZhJq2TBoo PgygwDU7Z2+tQVU+EZ453Gywz9/NMRFk1RWAZqrLix4ZtyIMvC6A1qfT2yH1Y7Fb Qh6tccQeLe4ezq5u4S/46R/fQXu3Txr92yVwzJJUuPyU0arF9rv5MmI8e6p7L1en yb74kSEaCe+/eMlsEj1Cc1dgthDNXGKIURHkRsILoweysCpesjiTg4qDcL+yTibV FP2wjVbniKESMKS6qL71tiT5sexvLsLwMNcGiHPj94qCIQuI7DLhLdBVsL5Su6gI sbtgv0dsq4auRYAbQdMaH1hFvu6WptsuttIbOMnz2Yegi2z28H8uVXkbk2WVLbqG ZESUwutGh8MzOL2RJ4jyyQq5sfo++CRGlfKjr6ImZRv03dv0pe/W85062cK5cKNs cgDDJjGRorOXW7dyU6jG2gRqODOQBObIv3w5efdq5OgzOWlbI4EC+Y5u1Z0JF/76 pSwtGXA6YhwC+9LLAlnVTHG+yOwuLmAICgoKcTbzTVDKA2YQZG/cYuQfI5S1wD8e X6urPx3Md2GCwLXQ9mzKBzKZUpu/Tuhx0NvwF4qVxy6x1PELjn68zuP7abDHr46r 57/09ooVN+iXXnEGMtQVS/OPvYHSa2NgTSZz6Y86lCRbZmUOOlK31RDNlMvYNA+s 3iIVHovno/JuJnTOE8LY =fQ8z -----END PGP SIGNATURE----- Merge tag 'arch-removal' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pul removal of obsolete architecture ports from Arnd Bergmann: "This removes the entire architecture code for blackfin, cris, frv, m32r, metag, mn10300, score, and tile, including the associated device drivers.

bpf: whitelist all syscalls for error injection
Error injection is a useful mechanism to fail arbitrary kernel
functions. However, it is often hard to guarantee an error propagates
appropriately to user space programs. By injecting into syscalls, we can
return arbitrary values to user space directly; this increases
flexibility and robustness in testing, allowing us to test user space
error paths effectively.
The following script, for example, fails calls to sys_open() from a
given pid:
from bcc import BPF
from sys import argv
pid = argv[1]
prog = r"""
int kprobe__SyS_open(struct pt_regs *ctx, const char *pathname, int flags)
{
u32 pid = bpf_get_current_pid_tgid();
if (pid == %s)
bpf_override_return(ctx, -ENOMEM);
return 0;
}
""" % pid
b = BPF(text=prog)
while 1:
b.perf_buffer_poll()
This patch whitelists all syscalls defined with SYSCALL_DEFINE and
COMPAT_SYSCALL_DEFINE for error injection. These changes are not
intended to be considered stable, and would normally be configured off.

syscalls/x86: auto-create compat_sys_*() prototypes
compat_sys_*() functions are no longer called from within the kernel on x86 except from the system call table. Linking the system call does not require compat_sys_*() function prototypes at least on x86. Therefore, generate compat_sys_*() prototypes on-the-fly within the COMPAT_SYSCALL_DEFINEx() macro, and remove x86-specific prototypes from various header files.
