2019-07-16fix: taprio: Change type of txtime-delay parameter to u32Vedang Patel
During the review of the iproute2 patches for txtime-assist mode, it was pointed out that it does not make sense for the txtime-delay parameter to be negative. So, change the type of the parameter from s32 to u32.

2019-07-16be2net: Signal that the device cannot transmit during reconfigurationBenjamin Poirier
While changing the number of interrupt channels, be2net stops adapter operation (including netif_tx_disable()) but it doesn't signal that it cannot transmit. This may lead dev_watchdog() to falsely trigger during that time. Add the missing call to netif_carrier_off(), following the pattern used in many other drivers. netif_carrier_on() is already taken care of in be_open().

2019-07-15net/mlx5e: Allow dissector meta key in tc flowerVlad Buslov
Recently, fl_flow_key->indev_ifindex int field was refactored into flow_dissector_key_meta field. With this, flower classifier also sets FLOW_DISSECTOR_KEY_META flow dissector key. However, mlx5 flower dissector validation code rejects filters that use flow dissector keys that are not supported. Add FLOW_DISSECTOR_KEY_META to the list of allowed dissector keys in __parse_cls_flower() to prevent following error when offloading flower classifier to mlx5: Error: mlx5_core: Unsupported key.

2019-07-15net/mlx5e: Rely on filter_dev instead of dissector keys for tunnelsVlad Buslov
Currently, tunnel attributes are parsed and inner header matching is used only when flow dissector specifies match on some of the supported encapsulation fields. When user tries to offload tc filter that doesn't match any encapsulation fields on tunnel device, mlx5 tc layer incorrectly sets to match packet header keys on encap header (outer header) and firmware rejects the rule with syndrome 0x7e1579 when creating new flow group. Change __parse_cls_flower() to determine whether tunnel is used based on fitler_dev tunnel info, instead of determining it indirectly by checking flow dissector enc keys.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "This is the bulk of pin control changes for the v5.3 kernel cycle: Core changes: - Device links can optionally be added between a pin control producer and its consumers. This will affect how the system power management is handled: a pin controller will not suspend before all of its consumers have been suspended. This was necessary for the ST Microelectronics STMFX expander and need to be tested on other systems as well: it makes sense to make this default in the long run. Right now it is opt-in per driver. - Drive strength can be specified in microamps. With decreases in silicon technology, milliamps isn't granular enough, let's make it possible to select drive strengths in microamps. Right now the Meson (AMlogic) driver needs this. New drivers: - New subdriver for the Tegra 194 SoC. - New subdriver for the Qualcomm SDM845. - New subdriver for the Qualcomm SM8150. - New subdriver for the Freescale i.MX8MN (Freescale is now a product line of NXP). - New subdriver for Marvell MV98DX1135. Driver improvements: - The Bitmain BM1880 driver now supports pin config in addition to muxing. - The Qualcomm drivers can now reserve some GPIOs as taken aside and not usable for users. This is used in ACPI systems to take out some GPIO lines used by the BIOS so that noone else (neither kernel nor userspace) will play with them by mistake and crash the machine. - A slew of refurbishing around the Aspeed drivers (board management controllers for servers) in preparation for the new Aspeed AST2600 SoC. - A slew of improvements over the SH PFC drivers as usual. - Misc cleanups and fixes" * tag 'pinctrl-v5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (106 commits) pinctrl: aspeed: Strip moved macros and structs from private header pinctrl: aspeed: Fix missed include pinctrl: baytrail: Use GENMASK() consistently pinctrl: baytrail: Re-use data structures from pinctrl-intel.h pinctrl: baytrail: Use defined macro instead of magic in byt_get_gpio_mux() pinctrl: qcom: Add SM8150 pinctrl driver dt-bindings: pinctrl: qcom: Add SM8150 pinctrl binding dt-bindings: pinctrl: qcom: Document missing gpio nodes pinctrl: aspeed: Add implementation-related documentation pinctrl: aspeed: Split out pinmux from general pinctrl pinctrl: aspeed: Clarify comment about strapping W1C pinctrl: aspeed: Correct comment that is no longer true MAINTAINERS: Add entry for ASPEED pinctrl drivers dt-bindings: pinctrl: aspeed: Convert AST2500 bindings to json-schema dt-bindings: pinctrl: aspeed: Convert AST2400 bindings to json-schema dt-bindings: pinctrl: aspeed: Split bindings document in two pinctrl: qcom: Add irq_enable callback for msm gpio pinctrl: madera: Fixup SPDX headers pinctrl: qcom: sdm845: Fix CONFIG preprocessor guard pinctrl: tegra: Add bitmask support for parked bits ...

2019-07-12ppp: mppe: Revert "ppp: mppe: Add softdep to arc4"Eric Biggers
Commit 0e5a610b5ca5 ("ppp: mppe: switch to RC4 library interface"), which was merged through the crypto tree for v5.3, changed ppp_mppe.c to use the new arc4_crypt() library function rather than access RC4 through the dynamic crypto_skcipher API. Meanwhile commit aad1dcc4f011 ("ppp: mppe: Add softdep to arc4") was merged through the net tree and added a module soft-dependency on "arc4". The latter commit no longer makes sense because the code now uses the "libarc4" module rather than "arc4", and also due to the direct use of arc4_crypt(), no module soft-dependency is required.

The cudbg_collect_mem_region() and cudbg_read_fw_mem() both use several hundred kilobytes of kernel stack space. One gets inlined into the other, which causes the stack usage to be combined beyond the warning limit when building with clang: drivers/net/ethernet/chelsio/cxgb4/cudbg_lib.c:1057:12: error: stack frame size of 1244 bytes in function 'cudbg_collect_mem_region' [-Werror,-Wframe-larger-than=] Restructuring cudbg_collect_mem_region() lets clang do the same optimization that gcc does and reuse the stack slots as it can see that the large variables are never used together. A better fix might be to avoid using cudbg_meminfo on the stack altogether, but that requires a larger rewrite.

2019-07-12tipc: ensure head->lock is initialisedChris Packham
tipc_named_node_up() creates a skb list. It passes the list to tipc_node_xmit() which has some code paths that can call skb_queue_purge() which relies on the list->lock being initialised. The spin_lock is only needed if the messages end up on the receive path but when the list is created in tipc_named_node_up() we don't necessarily know if it is going to end up there. Once all the skb list users are updated in tipc it will then be possible to update them to use the unlocked variants of the skb list functions and initialise the lock when we know the message will follow the receive path.
