git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk fixes from Stephen Boyd: "Fixes for various clk driver issues that happened because of code we merged this merge window. The Amlogic driver was missing some flags causing rates to be rounded improperly or clk_set_rate() to fail. The Samsung driver wasn't freeing everything on error paths and improperly saving/restoring PLL state across suspend/resume. The at91 driver was calling msleep() too early when scheduling hadn't started, so we put in place a quick solution until we can handle this sort of problem in the core framework. There were also problems with the Allwinner driver and operator precedence being incorrect causing subtle bugs.

The max value of EPB can only be 0x0F. Attempting to set more than that triggers an "unchecked MSR access error" warning which happens in intel_pstate_hwp_force_min_perf() called via cpufreq stop_cpu(). However, it is not even necessary to touch the EPB from intel_pstate, because it is restored on every CPU online by the intel_epb.c code, so let that code do the right thing and drop the redundant (and incorrect) EPB update from intel_pstate.

2019-11-07ipv6: fixes rt6_probe() and fib6_nh->last_probe initEric Dumazet1-3/+10
While looking at a syzbot KCSAN report [1], I found multiple issues in this code : 1) fib6_nh->last_probe has an initial value of 0. While probably okay on 64bit kernels, this causes an issue on 32bit kernels since the time_after(jiffies, 0 + interval) might be false ~24 days after boot (for HZ=1000) 2) The data-race found by KCSAN I could use READ_ONCE() and WRITE_ONCE(), but we also can take the opportunity of not piling-up too many rt6_probe_deferred() works by using instead cmpxchg() so that only one cpu wins the race.

2019-11-07net: hns: Fix the stray netpoll locks causing deadlock in NAPI pathSalil Mehta3-25/+1
This patch fixes the problem of the spin locks, originally meant for the netpoll path of hns driver, causing deadlock in the normal NAPI poll path. The issue happened due to the presence of the stray leftover spin lock code related to the netpoll, whose support was earlier removed from the HNS[1], got activated due to enabling of NET_POLL_CONTROLLER switch. Earlier background: The netpoll handling code originally had this bug(as identified by Marc Zyngier[2]) of wrong spin lock API being used which did not disable the interrupts and hence could cause locking issues. i.e. if the lock were first acquired in context to thread like 'ip' util and this lock if ever got later acquired again in context to the interrupt context like TX/RX (Interrupts could always pre-empt the lock holding task and acquire the lock again) and hence could cause deadlock. Proposed Solution: 1. If the netpoll was enabled in the HNS driver, which is not right now, we could have simply used spin_[un]lock_irqsave() 2. But as netpoll is disabled, therefore, it is best to get rid of the existing locks and stray code for now. This should solve the problem reported by Marc.

2019-11-07pinctrl: stmfx: fix valid_mask init sequenceAmelie Delaunay1-14/+0
With stmfx_pinctrl_gpio_init_valid_mask callback, gpio_valid_mask was used to initialize gpiochip valid_mask for gpiolib. But gpio_valid_mask was not yet initialized. gpio_valid_mask required gpio-ranges to be registered, this is the case after gpiochip_add_data call. But init_valid_mask callback is also called under gpiochip_add_data. gpio_valid_mask initialization cannot be moved before gpiochip_add_data because gpio-ranges are not registered. So, it is not possible to use init_valid_mask callback. To avoid this issue, get rid of valid_mask and rely on ranges.

In L2 tests that filter packets by destination MAC address we need to prevent false positives that can occur if we add an address that collides with the existing ones. To fix this, lets manually check if the new address to be added is already present in the NIC and use a different one if so. For Hash filtering this also envolves converting the address to the hash.

2019-11-06SMB3: Fix persistent handles reconnectPavel Shilovsky1-0/+1
When the client hits a network reconnect, it re-opens every open file with a create context to reconnect a persistent handle. All create context types should be 8-bytes aligned but the padding was missed for that one. As a result, some servers don't allow us to reconnect handles and return an error. The problem occurs when the problematic context is not at the end of the create request packet. Fix this by adding a proper padding at the end of the reconnect persistent handle context.

2019-11-06drm/amdgpu: add dummy read by engines for some GCVM status registers in gfx10changzhu4-6/+64
The GRBM register interface is now capable of bursting 1 cycle per register wr->wr, wr->rd much faster than previous muticycle per transaction done interface. This has caused a problem where status registers requiring HW to update have a 1 cycle delay, due to the register update having to go through GRBM. For cp ucode, it has realized dummy read in cp firmware.It covers the use of WAIT_REG_MEM operation 1 case only.So it needs to call gfx_v10_0_wait_reg_mem in gfx10. Besides it also needs to add warning to update firmware in case firmware is too old to have function to realize dummy read in cp firmware. For sdma ucode, it hasn't realized dummy read in sdma firmware. sdma is moved to gfxhub in gfx10. So it needs to add dummy read in driver between amdgpu_ring_emit_wreg and amdgpu_ring_emit_reg_wait for sdma_v5_0.

If a pnet table entry is to be added mentioning a valid ethernet interface, but an invalid infiniband or ISM device, the dev_put() operation for the ethernet interface is called twice, resulting in a negative refcount for the ethernet interface, which disables removal of such a network interface.

Jakub Kicinski says: ==================== net/tls: add a TX lock Some time ago Pooja and Mallesham started reporting crashes with an async accelerator. After trying to poke the existing logic into shape I came to the conclusion that it can't be trusted, and to preserve our sanity we should just add a lock around the TX side. First patch removes the sk_write_pending checks from the write space callbacks. Those don't seem to have a logical justification. Patch 2 adds the TX lock and patch 3 associated test (which should hang with current net). Mallesham reports that even with these fixes applied the async accelerator workload still occasionally hangs waiting for socket memory. I suspect that's strictly related to the way async crypto is integrated in TLS, so I think we should get these into net or net-next and move from there. ==================== Signed-off-by: David S.
