2019-08-15qed: Add driver API for flashing the config attributes.Sudarsana Reddy Kalluru
The patch adds driver interface for reading the config attributes from user provided buffer, and updates these values on nvm config flash partition. This is basically an expansion of our existing ethtool -f implementation. The management FW has exposed an additional method of configuring some of the nvram options, and this makes use of that. This implementation will come into use when newer FW files which contain configuration directives employing this API will be provided to ethtool -f.

2019-08-15ALSA: usb-audio: Fix a stack buffer overflow bug in check_input_termHui Peng
`check_input_term` recursively calls itself with input from device side (e.g., uac_input_terminal_descriptor.bCSourceID) as argument (id). In `check_input_term`, if `check_input_term` is called with the same `id` argument as the caller, it triggers endless recursive call, resulting kernel space stack overflow. This patch fixes the bug by adding a bitmap to `struct mixer_build` to keep track of the checked ids and stop the execution if some id has been checked (similar to how parse_audio_unit handles unitid argument).

2019-08-15net: myri10ge: fix memory leaksWenwen Wang
In myri10ge_probe(), myri10ge_alloc_slices() is invoked to allocate slices related structures. Later on, myri10ge_request_irq() is used to get an irq. However, if this process fails, the allocated slices related structures are not deallocated, leading to memory leaks. To fix this issue, revise the target label of the goto statement to 'abort_with_slices'. Signed-off-by: Wenwen Wang <wenwen@cs.uga.edu> Signed-off-by: David S. Miller <davem@davemloft.net>

The first two patches are for the kvaser_pciefd driver: Christer Beskow removes unnecessary code in the kvaser_pciefd_pwm_stop() function, YueHaibing removes the unused including of <linux/version.h>. In the next patch YueHaibing also removes the unused including of <linux/version.h> in the f81601 driver. In the ti_hecc driver the next 6 patches are by me and fix checkpatch warnings. YueHaibing's patch removes an unused variable in the ti_hecc_mailbox_read() function. The next 6 patches all target the xilinx_can driver. Anssi Hannula's patch fixes a chip start failure with an invalid bus. The patch by Venkatesh Yadav Abbarapu skips an error message in case of a deferred probe. The 3 patches by Appana Durga Kedareswara rao fix the RX and TX path for CAN-FD frames. Srinivas Neeli's patch fixes the bit timing calculations for CAN-FD. The next 12 patches are by me and several checkpatch warnings in the af_can, raw and bcm components. Thomas Gleixner provides a patch for the bcm, which switches the timer to HRTIMER_MODE_SOFT and removes the hrtimer_tasklet. Then 6 more patches by me for the gw component, which fix checkpatch warnings, followed by 2 patches by Oliver Hartkopp to add CAN-FD support. The vcan driver gets 3 patches by me, fixing checkpatch warnings. And finally a patch by Andre Hartmann to fix typos in CAN's netlink header. ====================
2019-08-15net: tls, fix sk_write_space NULL write when tx disabledJohn Fastabend
The ctx->sk_write_space pointer is only set when TLS tx mode is enabled. When running without TX mode its a null pointer but we still set the sk sk_write_space pointer on close(). Fix the close path to only overwrite sk->sk_write_space when the current pointer is to the tls_write_space function indicating the tls module should clean it up properly as well.

2019-08-15nfsd: use i_wrlock instead of rcu for nfsdfs i_privateJ. Bruce Fields
synchronize_rcu() gets called multiple times each time a client is destroyed. If the laundromat thread has a lot of clients to destroy, the delay can be noticeable. This was causing pynfs test RENEW3 to fail. We could embed an rcu_head in each inode and do the kref_put in an rcu callback. But simplest is just to take a lock here. (I also wonder if the laundromat thread would be better replaced by a bunch of scheduled work or timers or something.) Signed-off-by: J. Bruce Fields <bfields@redhat.com>

Commit bd11b3a391e3 ("io_uring: don't use iov_iter_advance() for fixed buffers") introduced an optimization to avoid using the slow iov_iter_advance by manually populating the iov_iter iterator in some cases. However, the computation of the iterator count field was erroneous: The first bvec was always accounted for an extent of page size even if the bvec length was smaller. In consequence, some I/O operations on fixed buffers were unable to operate on the full extent of the buffer, consistently skipping some bytes at the end of it.

2019-08-15PCI: Reset both NVIDIA GPU and HDA in ThinkPad P50 workaroundLyude Paul
quirk_reset_lenovo_thinkpad_50_nvgpu() resets NVIDIA GPUs to work around an apparent BIOS defect. It previously used pci_reset_function(), and the available method was a bus reset, which was fine because there was only one function on the bus. After b516ea586d71 ("PCI: Enable NVIDIA HDA controllers"), there are now two functions (the HDA controller and the GPU itself) on the bus, so the reset fails. Use pci_reset_bus() explicitly instead of pci_reset_function() since it's OK to reset both devices.

Switch the buffer allocation to use the uses_dma flag used by the rest of the USB code, and create a helper in hcd.h that checks this flag as well as the CONFIG_HAS_DMA to simplify the caller a bit.

2019-08-15usb: don't create dma pools for HCDs with a localmem_poolChristoph Hellwig
If the HCD provides a localmem pool we will never use the DMA pools, so don't create them.

2019-08-15usb: chipidea: imx: fix EPROBE_DEFER support during driver probeAndré Draszik
If driver probe needs to be deferred, e.g. because ci_hdrc_add_device() isn't ready yet, this driver currently misbehaves badly: a) success is still reported to the driver core (meaning a 2nd probe attempt will never be done), leaving the driver in a dysfunctional state and the hardware unusable b) driver remove / shutdown OOPSes: [ 206.786916] Unable to handle kernel paging request at virtual address fffffdff [ 206.794148] pgd = 880b9f82 [ 206.796890] [fffffdff] *pgd=abf5e861, *pte=00000000, *ppte=00000000 [ 206.803179] Internal error: Oops: 37 [#1] PREEMPT SMP ARM [ 206.808581] Modules linked in: wl18xx evbug [ 206.813308] CPU: 1 PID: 1 Comm: systemd-shutdow Not tainted 4.19.35+gf345c93b4195 #1 [ 206.821053] Hardware name: Freescale i.MX7 Dual (Device Tree) [ 206.826813] PC is at ci_hdrc_remove_device+0x4/0x20 [ 206.831699] LR is at ci_hdrc_imx_remove+0x20/0xe8 [ 206.836407] pc : [<805cd4b0>] lr : [<805d62cc>] psr: 20000013 [ 206.842678] sp : a806be40 ip : 00000001 fp : 80adbd3c [ 206.847906] r10: 80b1b794 r9 : 80d5dfe0 r8 : a8192c44 [ 206.853136] r7 : 80db93a0 r6 : a8192c10 r5 : a8192c00 r4 : a93a4a00 [ 206.859668] r3 : 00000000 r2 : a8192ce4 r1 : ffffffff r0 : fffffdfb [ 206.866201] Flags: nzCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment none [ 206.873341] Control: 10c5387d Table: a9e0c06a DAC: 00000051 [ 206.879092] Process systemd-shutdow (pid: 1, stack limit = 0xb271353c) [ 206.885624] Stack: (0xa806be40 to 0xa806c000) [ 206.889992] be40: a93a4a00 805d62cc a8192c1c a8170e10 a8192c10 8049a490 80d04d08 00000000 [ 206.898179] be60: 00000000 80d0da2c fee1dead 00000000 a806a000 00000058 00000000 80148b08 [ 206.906366] be80: 01234567 80148d8c a9858600 00000000 00000000 00000000 00000000 80d04d08 [ 206.914553] bea0: 00000000 00000000 a82741e0 a9858600 00000024 00000002 a9858608 00000005 [ 206.922740] bec0: 0000001e 8022c058 00000000 00000000 a806bf14 a9858600 00000000 a806befc [ 206.930927] bee0: a806bf78 00000000 7ee12c30 8022c18c a806bef8 a806befc 00000000 00000001 [ 206.939115] bf00: 00000000 00000024 a806bf14 00000005 7ee13b34 7ee12c68 00000004 7ee13f20 [ 206.947302] bf20: 00000010 7ee12c7c 00000005 7ee12d04 0000000a 76e7dc00 00000001 80d0f140 [ 206.955490] bf40: ab637880 a974de40 60000013 80d0f140 ab6378a0 80d04d08 a8080470 a9858600 [ 206.963677] bf60: a9858600 00000000 00000000 8022c24c 00000000 80144310 00000000 00000000 [ 206.971864] bf80: 80101204 80d04d08 00000000 80d04d08 00000000 00000000 00000003 00000058 [ 206.980051] bfa0: 80101204 80101000 00000000 00000000 fee1dead 28121969 01234567 00000000 [ 206.988237] bfc0: 00000000 00000000 00000003 00000058 00000000 00000000 00000000 00000000 [ 206.996425] bfe0: 0049ffb0 7ee13d58 0048a84b 76f245a6 60000030 fee1dead 00000000 00000000 [ 207.004622] [<805cd4b0>] (ci_hdrc_remove_device) from [<805d62cc>] (ci_hdrc_imx_remove+0x20/0xe8) [ 207.013509] [<805d62cc>] (ci_hdrc_imx_remove) from [<8049a490>] (device_shutdown+0x16c/0x218) [ 207.022050] [<8049a490>] (device_shutdown) from [<80148b08>] (kernel_restart+0xc/0x50) [ 207.029980] [<80148b08>] (kernel_restart) from [<80148d8c>] (sys_reboot+0xf4/0x1f0) [ 207.037648] [<80148d8c>] (sys_reboot) from [<80101000>] (ret_fast_syscall+0x0/0x54) [ 207.045308] Exception stack(0xa806bfa8 to 0xa806bff0) [ 207.050368] bfa0: 00000000 00000000 fee1dead 28121969 01234567 00000000 [ 207.058554] bfc0: 00000000 00000000 00000003 00000058 00000000 00000000 00000000 00000000 [ 207.066737] bfe0: 0049ffb0 7ee13d58 0048a84b 76f245a6 [ 207.071799] Code: ebffffa8 e3a00000 e8bd8010 e92d4010 (e5904004) [ 207.078021] ---[ end trace be47424e3fd46e9f ]--- [ 207.082647] Kernel panic - not syncing: Fatal exception [ 207.087894] ---[ end Kernel panic - not syncing: Fatal exception ]--- c) the error path in combination with driver removal causes imbalanced calls to the clk_*() and pm_()* APIs a) happens because the original intended return value is overwritten (with 0) by the return code of regulator_disable() in ci_hdrc_imx_probe()'s error path b) happens because ci_pdev is -EPROBE_DEFER, which causes ci_hdrc_remove_device() to OOPS Fix a) by being more careful in ci_hdrc_imx_probe()'s error path and not overwriting the real error code Fix b) by calling the respective cleanup functions during remove only when needed (when ci_pdev != NULL, i.e. when everything was initialised correctly). This also has the side effect of not causing imbalanced clk_*() and pm_*() API calls as part of the error code path.
