net: ethernet: sun: Zero initialize class in default case in niu_add_ethtool_tcam_entry
When building with -Wsometimes-uninitialized, Clang warns: drivers/net/ethernet/sun/niu.c:7466:5: warning: variable 'class' is used uninitialized whenever switch default is taken [-Wsometimes-uninitialized] The default case can never happen because i can only be 0 to 3 (NIU_L3_PROG_CLS is defined as 4). To make this clear to Clang, just zero initialize class in the default case (use the macro CLASS_CODE_UNRECOG to make it clear this shouldn't happen).

fou, fou6: avoid uninit-value in gue_err() and gue6_err()
My prior commit missed the fact that these functions
were using udp_hdr() (aka skb_transport_header())
to get access to GUE header.
Since pskb_transport_may_pull() does not exist yet, we have to add
transport_offset to our pskb_may_pull() calls.

net: sched: fix potential use-after-free in __tcf_chain_put()
When used with unlocked classifier that have filters attached to actions
with goto chain, __tcf_chain_put() for last non action reference can race
with calls to same function from action cleanup code that releases last
action reference. In this case action cleanup handler could free the chain
if it executes after all references to chain were released, but before all
concurrent users finished using it. Modify __tcf_chain_put() to only access
tcf_chain fields when holding block->lock. Remove local variables that were
used to cache some tcf_chain fields and are no longer needed because their
values can now be obtained directly from chain under block->lock
protection.

vhost: silence an unused-variable warning
On some architectures, the MMU can be disabled, leading to access_ok() becoming an empty macro that does not evaluate its size argument, which in turn produces an unused-variable warning: drivers/vhost/vhost.c:1191:9: error: unused variable 's' [-Werror,-Wunused-variable] size_t s = vhost_has_feature(vq, VIRTIO_RING_F_EVENT_IDX) ? 2 : 0; Mark the variable as __maybe_unused to shut up that warning.

connector: fix unsafe usage of ->real_parent
proc_exit_connector() uses ->real_parent lockless. This is not
safe that its parent can go away at any moment, so use RCU to
protect it, and ensure that this task is not released.

Since the first one, we've added basic unit testing of the three system calls, that resides in liburing like the other unit tests that we have so far. It'll take a while to get full coverage of it, but we're working towards it. I've also added two basic test programs to tools/io_uring. One uses the raw interface and has support for all the various features that io_uring supports outside of standard IO, like fixed files, fixed IO buffers, and polled IO. The other uses the liburing API, and is a simplified version of cp(1). This adds support for a new IO interface, io_uring. io_uring allows an application to communicate with the kernel through two rings, the submission queue (SQ) and completion queue (CQ) ring. This allows for very efficient handling of IOs, see the v5 posting for some basic numbers: https://lore.kernel.org/linux-block/20190116175003.17880-1-axboe@kernel.dk/ Outside of just efficiency, the interface is also flexible and extendable, and allows for future use cases like the upcoming NVMe key-value store API, networked IO, and so on. It also supports async buffered IO, something that we've always failed to support in the kernel. Outside of basic IO features, it supports async polled IO as well. This particular feature has already been tested at Facebook months ago for flash storage boxes, with 25-33% improvements. It makes polled IO actually useful for real world use cases, where even basic flash sees a nice win in terms of efficiency, latency, and performance. These boxes were IOPS bound before, now they are not. This series adds three new system calls. One for setting up an io_uring instance (io_uring_setup(2)), one for submitting/completing IO (io_uring_enter(2)), and one for aux functions like registrating file sets, buffers, etc (io_uring_register(2)). Through the help of Arnd, I've coordinated the syscall numbers so merge on that front should be painless. Jon did a writeup of the interface a while back, which (except for minor details that have been tweaked) is still accurate. Find that here: https://lwn.net/Articles/776703/ Huge thanks to Al Viro for helping getting the reference cycle code correct, and to Jann Horn for his extensive reviews focused on both security and bugs in general. There's a userspace library that provides basic functionality for applications that don't need or want to care about how to fiddle with the rings directly. It has helpers to allow applications to easily set up an io_uring instance, and submit/complete IO through it without knowing about the intricacies of the rings. It also includes man pages (thanks to Jeff Moyer), and will continue to grow support helper functions and features as time progresses. Find it here: git://git.kernel.dk/liburing Fio has full support for the raw interface, both in the form of an IO engine (io_uring), but also with a small test application (t/io_uring) that can exercise and benchmark the interface" * tag 'io_uring-2019-03-06' of git://git.kernel.dk/linux-block: io_uring: add a few test tools io_uring: allow workqueue item to handle multiple buffered requests io_uring: add support for IORING_OP_POLL io_uring: add io_kiocb ref count io_uring: add submission polling io_uring: add file set registration net: split out functions related to registering inflight socket files io_uring: add support for pre-mapped user IO buffers block: implement bio helper to add iter bvec pages to bio io_uring: batch io_kiocb allocation io_uring: use fget/fput_many() for file references fs: add fget_many() and fput_many() io_uring: support for IO polling io_uring: add fsync support Add io_uring IO interface |

vxlan: Fix GRO cells race condition between receive and link delete
If we receive a packet while deleting a VXLAN device, there's a chance vxlan_rcv() is called at the same time as vxlan_dellink(). This is fine, except that vxlan_dellink() should never ever touch stuff that's still in use, such as the GRO cells list. Otherwise, vxlan_rcv() crashes while queueing packets via gro_cells_receive(). Move the gro_cells_destroy() to vxlan_uninit(), which runs after the RCU grace period is elapsed and nothing needs the gro_cells anymore. This is now done in the same way as commit |

rxrpc: Fix client call connect/disconnect race
rxrpc_disconnect_client_call() reads the call's connection ID protocol
value (call->cid) as part of that function's variable declarations. This
is bad because it's not inside the locked section and so may race with
someone granting use of the channel to the call.
This manifests as an assertion failure (see below) where the call in the
presumed channel (0 because call->cid wasn't set when we read it) doesn't
match the call attached to the channel we were actually granted (if 1, 2 or
3).
Fix this by moving the read and dependent calculations inside of the
channel_lock section. Also, only set the channel number and pointer
variables if cid is not zero (ie. unset).
This problem can be induced by injecting an occasional error in
rxrpc_wait_for_channel() before the call to schedule().
Make two further changes also:
(1) Add a trace for wait failure in rxrpc_connect_call().
(2) Drop channel_lock before BUG'ing in the case of the assertion failure.
The failure causes a trace akin to the following:
rxrpc: Assertion failed - 18446612685268945920(0xffff8880beab8c00) == 18446612685268621312(0xffff8880bea69800) is false

route: set the deleted fnhe fnhe_daddr to 0 in ip_del_fnhe to fix a race
The race occurs in __mkroute_output() when 2 threads lookup a dst:
CPU A CPU B
find_exception()
find_exception() [fnhe expires]
ip_del_fnhe() [fnhe is deleted]
rt_bind_exception()
In rt_bind_exception() it will bind a deleted fnhe with the new dst, and
this dst will get no chance to be freed. It causes a dev defcnt leak and
consecutive dmesg warnings:
unregister_netdevice: waiting for ethX to become free. Usage count = 1
Especially thanks Jon to identify the issue.
This patch fixes it by setting fnhe_daddr to 0 in ip_del_fnhe() to stop
binding the deleted fnhe with a new dst when checking fnhe's fnhe_daddr
and daddr in rt_bind_exception().
It works as both ip_del_fnhe() and rt_bind_exception() are protected by
fnhe_lock and the fhne is freed by kfree_rcu().

This is the bulk of GPIO changes for the v5.1 cycle:
Core changes: - The big change this time around is the irqchip handling in the qualcomm pin controllers, closely coupled with the gpiochip. This rework, in a classic fall-between-the-chairs fashion has been sidestepped for too long. The Qualcomm IRQchips using the SPMI and SSBI transport mechanisms have been rewritten to use hierarchical irqchip. This creates the base from which I intend to gradually pull support for hierarchical irqchips into the gpiolib irqchip helpers to cut down on duplicate code. We have too many hacks in the kernel because people have been working around the missing hierarchical irqchip for years, and once it was there, noone understood it for a while. We are now slowly adapting to using it. This is why this pull requests include changes to MFD, SPMI, IRQchip core and some ARM Device Trees pertaining to the Qualcomm chip family. Since Qualcomm have so many chips and such large deployments it is paramount that this platform gets this right, and now it (hopefully) does. - Core support for pull-up and pull-down configuration, also from the device tree. When a simple GPIO chip support a "off or on" pull-up or pull-down resistor, we provide a way to set this up using machine descriptors or device tree. If more elaborate control of pull up/down (such as resistance shunt setting) is required, drivers should be phased over to use pin control. We do not yet provide a userspace ABI for this pull up-down setting but I suspect the makers are going to ask for it soon enough. PCA953x is the first user of this new API. - The GPIO mockup driver has been revamped after some discussion improving the IRQ simulator in the process. The idea is to make it possible to use the mockup for both testing and virtual prototyping, e.g. when you do not yet have a GPIO expander to play with but really want to get something to develop code around before hardware is available. It's neat. The blackbox testing usecase is currently making its way into kernelci. - ACPI GPIO core preserves non direction flags when updating flags. - A new device core helper for devm_platform_ioremap_resource() is funneled through the GPIO tree with Greg's ACK. New drivers: - TQ-Systems QTMX86 GPIO controllers (using port-mapped I/O) - Gateworks PLD GPIO driver (vaccumed up from OpenWrt) - AMD G-Series PCH (Platform Controller Hub) GPIO driver. - Fintek F81804 & F81966 subvariants. - PCA953x now supports NXP PCAL6416. Driver improvements: - IRQ support on the Nintendo Wii (Hollywood) GPIO. - get_direction() support for the MVEBU driver. - Set the right output level on SAMA5D2. - Drop the unused irq trigger setting on the Spreadtrum driver. - Wakeup support for PCA953x. - A slew of cleanups in the various Intel drivers. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJcgoLEAAoJEEEQszewGV1zjBAP/3OmTFGv49PFmJwSx+PlLiYf V6/UPaQzq81CGSMtHxbS51TyP9Id7PCfsacbuFYutzn0D1efvl7jrkb8qJ6fVvCM bl/i6q8ipRTPzAf1hD3QCgCe3BXCA064/OcPrz987oIvI3bJQXsmBjBSXHWr4Cwa WfB5DX/afn9TK3XHhMQGfw5f0d+TtnKAs90RTTVKiz9Ow8eFYZJOhgPkvhCR3Gi9 YJIzIAiwhHZ7/zauo4JAYFU/O/Z3YEC5zeLne2ItebzNooRkSxdz0c9Hs7HlCZmU 930Uv9jNN89N3vPqpZzAHtPvwDOmAILMWvKy9xRSp+eoIukarRJgF7ALPk7QWxK1 yy+tGj4dXBQ6tI8W3wUN1WgjNpii3K1HbJ+1LQVQL2/q9o+3YXXqmjdjuw7C8YYV 5ystNrUppkgfIIciHL4lhqw3wKJJhVEAns2V245hIitoShT+RvIg8GQbGZmWlQFd YsHbynqHL9iwfRNv26kEqZXZOo/4D1t6Scw+OPVyba2Wyttf+qbmg+XaYMqFaxYW mfydvdtymeCOUIPJMzw58KGPUTXJ4UPLENyayXNUHokr1a8VO8OIthY7zwi0CpvJ IcsAY9zoGxvfbRV922mlIsw3oOBcM2IN2lC9sY469ZVnjBrdC3rsQpIBZr+Vzz8i YlUfXLSGSyuUZUz//2eG =VoVC -----END PGP SIGNATURE----- Merge tag 'gpio-v5.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v5.1 cycle: Core changes: - The big change this time around is the irqchip handling in the qualcomm pin controllers, closely coupled with the gpiochip.

A couple of bug fixes and a bunch of code cleanup:
* Fix a use after free error in a certain error situation. * Fix some flag handling issues in the SSIF (I2C) IPMI driver. * A bunch of cleanups, spacing issues, converting pr_xxx to dev_xxx, use standard UUID handling, and some other minor stuff. * The IPMI code was creating a platform device if none was supplied. Instead of doing that, have every source that creates an IPMI device supply a device struct. This fixes several issues,including a crash in one situation, and cleans things up a bit. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE/Q1c5nzg9ZpmiCaGYfOMkJGb/4EFAlx+qm8ACgkQYfOMkJGb /4F8rxAAmzPgNowsV6T0T9ZHg35XRx31vjPyrCZsbzBv0ahSr6mIwoz41iZAz1z8 bGjJJ8LA6oqfG9PsolUMc8RsiHXOlCXR2qpcx7r6N1Ptj/7VNdy9UneIl5UwnxhP 1mGkWJeKYQn3tXVa8PjzfX9kZ3gxcooL9q+0+m2E6O5M/ldzUvWDGXRfoVD+Uy88 RoPd3AeUnaIBDoB42l5a9EzPr+xXVKYSPl7WLEgV4GTwWRANvFP88PSXOenzo35b G08Yq6+u1M1QY/HJLLtvanHWpkBrHGLr+XTdXKAxKgV40s2flL4xBSfYWF8RFLCW R74HXwSOSvpZEhROrleaj2GcL1DsJhQj5Q+DsYAIyMJSkavPtFZU2TRL+nOUoe39 wJdS5F0i7qhnNPtj0Iatz9zOwY5apT5vj7/MAEXIQi2t+p1m7ado1kw7CDaQsTOK ONzhlxCZ6b6rvdpJ7hH8u1AAejRoZ8tq9rAdsKSJvgTPiDrtLDlouPkAQCJpl7Ub VsByzrXeL2a6yEW9W5V2LH2UXandRAKguzvnYDOEbY5bVOmQmEaoDWTvoC5jRr6K MRobCgC96UpNgY4SXJSoZunrFjuGJR0CN66BJd52afcxEM/iu50Z8+DJ92KnDjhY E8XVvC5fXH6EMF1yDIt51GiDyHYQXX1TaNArFuFZWaEJ8e2gT6M= =LSch -----END PGP SIGNATURE----- Merge tag 'for-linus-5.1' of git://github.com/cminyard/linux-ipmi Pull IPMI updates from Corey Minyard: "A couple of bug fixes and a bunch of code cleanup: - Fix a use after free error in a certain error situation. - Fix some flag handling issues in the SSIF (I2C) IPMI driver. - A bunch of cleanups, spacing issues, converting pr_xxx to dev_xxx, use standard UUID handling, and some other minor stuff. - The IPMI code was creating a platform device if none was supplied.

gfs2: Fix missed wakeups in find_insert_glock
Mark Syms has reported seeing tasks that are stuck waiting in find_insert_glock. It turns out that struct lm_lockname contains four padding bytes on 64-bit architectures that function glock_waitqueue doesn't skip when hashing the glock name. As a result, we can end up waking up the wrong waitqueue, and the waiting tasks may be stuck forever. Fix that by using ht_parms.key_len instead of sizeof(struct lm_lockname) for the key length.

gpio: gpio-omap: fix level interrupt idling
Tony notes that the GPIO module does not idle when level interrupts are in use, as the wakeup appears to get stuck. After extensive investigation, it appears that the wakeup will only be cleared if the interrupt status register is cleared while the interrupt is enabled. However, we are currently clearing it with the interrupt disabled for level-based interrupts. It is acknowledged that this observed behaviour conflicts with a statement in the TRM: CAUTION After servicing the interrupt, the status bit in the interrupt status register (GPIOi.GPIO_IRQSTATUS_0 or GPIOi.GPIO_IRQSTATUS_1) must be reset and the interrupt line released (by setting the corresponding bit of the interrupt status register to 1) before enabling an interrupt for the GPIO channel in the interrupt-enable register (GPIOi.GPIO_IRQSTATUS_SET_0 or GPIOi.GPIO_IRQSTATUS_SET_1) to prevent the occurrence of unexpected interrupts when enabling an interrupt for the GPIO channel. However, this does not appear to be a practical problem. Further, as reported by Grygorii Strashko <grygorii.strashko@ti.com>, the TI Android kernel tree has an earlier similar patch as "GPIO: OMAP: Fix the sequence to clear the IRQ status" saying: if the status is cleared after disabling the IRQ then sWAKEUP will not be cleared and gates the module transition When we unmask the level interrupt after the interrupt has been handled, enable the interrupt and only then clear the interrupt. If the interrupt is still pending, the hardware will re-assert the interrupt status. Should the caution note in the TRM prove to be a problem, we could use a clear-enable-clear sequence instead.
