commit b71121b4 upstream. Device notifications are not received after the first interface is closed; since there is an unregister for notifications on every interface close. Correct this by unregistering for device notifications only when the last interface is closed. Also, make all operations on the i40iw_notifiers_registered atomic as it can be read/modified concurrently. Fixes: 8e06af71 ("i40iw: add main, hdr, status") Signed-off-by:

commit 07c72d7d upstream. Send a zero length last streaming mode message for loopback connections to synchronize between accepting QP and connecting QP. This avoids data transfer to start on the accepting QP before the connecting QP is in RTS. Also remove function i40iw_loopback_nop() as it is no longer used.

commit 5dfd5e5e upstream. Add NULL check for pdata and pdata->addr before the memcpy in i40iw_form_cm_frame(). This fixes a NULL pointer de-reference which occurs when the MPA private data pointer is NULL. Also only copy pdata->size bytes in the memcpy to prevent reading past the length of the private data buffer provided by upper layer.

commit 5a7d87da upstream. gcc is apparently unablel to track the state of the local 'resp_v2' variable across the kzalloc() function, and warns about the response variable being used without an initialization: drivers/net/wireless/intel/iwlwifi/mvm/nvm.c: In function ‘iwl_mvm_update_mcc’: drivers/net/wireless/intel/iwlwifi/mvm/nvm.c:727:36: warning: ‘mcc_resp_v1’ may be used uninitialized in this function [-Wmaybe-uninitialized] resp_cp->n_channels = mcc_resp_v1->n_channels; drivers/net/wireless/intel/iwlwifi/mvm/nvm.c:721:3: warning: ‘mcc_resp’ may be used uninitialized in this function [-Wmaybe-uninitialized] memcpy(resp_cp, mcc_resp, resp_len); The warning showed up in x86 allmodconfig after my patch to unhide -Wmaybe-uninitialized warnings by default was merged, though it always existed in randconfig builds. I did not catch the warning earlier because I was testing on ARM, which never produced the warning. This rearranges the code in a way that improves readability for both humans and the compiler, and that avoids the warning. Signed-off-by:

commit d5d0689a upstream. This fixes a pretty ancient bug that hasn't manifested itself until now. The scratchbuf for command queue is allocated only for 32 slots but is accessed with the queue write pointer - which can be up to 256. Since the scratch buf size was 16 and there are up to 256 TFDs we never passed a page boundary when accessing the scratch buffer, but when attempting to increase the size of the scratch buffer a panic was quick to follow when trying to access the address resulted in a page boundary.

commit e7c9bd1c upstream. The TX fifos are arranged consecutively in the SMEM, beginning with the regular fifos, and tailed by the internal fifos. In the current code, while trying to read the internal fifos, we read the fifos beginning with the index zero. By doing this we actually re-read the regular fifos. In order to read the internal fifos, start the reading index from the number of regular fifos configured by the fw. Signed-off-by:

commit 2c4a247e upstream. Fix an issue where nullfunc frames and block ack requests had the same tid as aggregation frames and were queued on a non aggregation queue. The pending frames counter included those frames but the check whether to decrement the pending frames counter relied on the tid status and not on the txq id. The result was an inconsistent state of the pending frames counter followed by a failure to remove the station. This failure triggered SYSASSERT 0x3421. In addition, fix a situation in DQA mode where the number of pending frames turned negative. This was due to the TX queue being on the IWL_EMPTYING_HW_QUEUE_DELBA state and its frames were still decremented. Even though the SYSASSERT issue is fixed when DQA is disabled, the issue is not completely solved when DQA is enabled and should still be fixed. Signed-off-by:

commit 3d89e547 upstream. Commit: e9532e69 ("sched/cputime: Fix steal time accounting vs. CPU hotplug") ... set rq->prev_* to 0 after a CPU hotplug comes back, in order to fix the case where (after CPU hotplug) steal time is smaller than rq->prev_steal_time. However, this should never happen. Steal time was only smaller because of the KVM-specific bug fixed by the previous patch. Worse, the previous patch triggers a bug on CPU hot-unplug/plug operation: because rq->prev_steal_time is cleared, all of the CPU's past steal time will be accounted again on hot-plug. Since the root cause has been fixed, we can just revert commit e9532e69. Signed-off-by:

commit 4f6aa326 upstream. To support UHS modes for Tegra an external regulator must be present to adjust the IO voltage accordingly. Even if the regulator is not present but the host supports the UHS modes and the device supports the UHS modes, then we will attempt to switch to a high-speed mode. Without an external regulator, Tegra will fail to switch to the high-speed mode. It has been found that with some SD cards, that once it has been switch to operate at a high-speed mode, all subsequent commands issues to the card will fail and so it will not be possible to switch back to a non high-speed mode and so the SD card initialisation will fail. The SDHCI core does not require that the host have an external regulator when switching to UHS modes and therefore, the Tegra SDHCI host controller should only advertise the UHS modes as being supported if the regulator for the IO voltage is present. Fortunately, Tegra has a vendor specific register which can be used to control which modes are advertised via the SDHCI_CAPABILITIES register. Hence, if there is no IO voltage regulator available for the Tegra SDHCI host, then don't advertise the UHS modes. Note that if the regulator is not available, we also don't advertise that the SDHCI is compatible with v3.0 of the SDHCI specification because this will read the SDHCI_CAPABILITIES_1 register which will enable other UHS modes. This fixes commit 7ad2ed1d ("mmc: tegra: enable UHS-I modes") which enables UHS mode without checking if the board can support them. Fixes: 7ad2ed1d ("mmc: tegra: enable UHS-I modes") Signed-off-by:

commit 8b6a3fe8 upstream. When tearing down an AUX buf for an event via perf_mmap_close(), __perf_event_output_stop() is called on the event's CPU to ensure that trace generation is halted before the process of unmapping and freeing the buffer pages begins. The callback is performed via cpu_function_call(), which ensures that it runs with interrupts disabled and is therefore not preemptible. Unfortunately, the current code grabs the per-cpu context pointer using get_cpu_ptr(), which unnecessarily disables preemption and doesn't pair the call with put_cpu_ptr(), leading to a preempt_count() imbalance and a BUG when freeing the AUX buffer later on: WARNING: CPU: 1 PID: 2249 at kernel/events/ring_buffer.c:539 __rb_free_aux+0x10c/0x120 Modules linked in: [...] Call Trace: [<ffffffff813379dd>] dump_stack+0x4f/0x72 [<ffffffff81059ff6>] __warn+0xc6/0xe0 [<ffffffff8105a0c8>] warn_slowpath_null+0x18/0x20 [<ffffffff8112761c>] __rb_free_aux+0x10c/0x120 [<ffffffff81128163>] rb_free_aux+0x13/0x20 [<ffffffff8112515e>] perf_mmap_close+0x29e/0x2f0 [<ffffffff8111da30>] ? perf_iterate_ctx+0xe0/0xe0 [<ffffffff8115f685>] remove_vma+0x25/0x60 [<ffffffff81161796>] exit_mmap+0x106/0x140 [<ffffffff8105725c>] mmput+0x1c/0xd0 [<ffffffff8105cac3>] do_exit+0x253/0xbf0 [<ffffffff8105e32e>] do_group_exit+0x3e/0xb0 [<ffffffff81068d49>] get_signal+0x249/0x640 [<ffffffff8101c273>] do_signal+0x23/0x640 [<ffffffff81905f42>] ? _raw_write_unlock_irq+0x12/0x30 [<ffffffff81905f69>] ? _raw_spin_unlock_irq+0x9/0x10 [<ffffffff81901896>] ? __schedule+0x2c6/0x710 [<ffffffff810022a4>] exit_to_usermode_loop+0x74/0x90 [<ffffffff81002a56>] prepare_exit_to_usermode+0x26/0x30 [<ffffffff81906d1b>] retint_user+0x8/0x10 This patch uses this_cpu_ptr() instead of get_cpu_ptr(), since preemption is already disabled by the caller.

commit af06d4f7 upstream. 0day found a boot warning triggered in rcu_perf_writer() on !SMP kernel: WARN_ON(rcu_gp_is_normal() && gp_exp); , the root cause of which is trying to measure expedited grace periods(by setting gp_exp to true by default) when all the grace periods are normal(TINY RCU only has normal grace periods). However, such a mis-setting would only result in failing to measure the performance for a specific kind of grace periods, therefore using a WARN_ON to check this is a little overkilling. We could handle this inside rcuperf module via some error messages to tell users about the mis-settings. Therefore this patch removes the WARN_ON in rcu_perf_writer() and handles those checkings in rcu_perf_init() with plain if() code. Moreover, this patch changes the default value of gp_exp to 1) align with rcutorture tests and 2) make the default setting work for all RCU implementations by default. Suggested-by:

commit d248220f upstream. Since commit 6ce0d200 ("ARM: dma: Use dma_pfn_offset for dma address translation"), dma_to_pfn() already returns the PFN with the physical memory start offset so we don't need to add it again. This fixes USB mass storage lock-up problem on systems that can't do DMA over the entire physical memory range (e.g.) Keystone 2 systems with 4GB RAM can only do DMA over the first 2GB. [K2E-EVM]. What happens there is that without this patch SCSI layer sets a wrong bounce buffer limit in scsi_calculate_bounce_limit() for the USB mass storage device. dma_max_pfn() evaluates to 0x8fffff and bounce_limit is set to 0x8fffff000 whereas maximum DMA'ble physical memory on Keystone 2 is 0x87fffffff. This results in non DMA'ble pages being given to the USB controller and hence the lock-up. NOTE: in the above case, USB-SCSI-device's dma_pfn_offset was showing as 0. This should have really been 0x780000 as on K2e, LOWMEM_START is 0x80000000 and HIGHMEM_START is 0x800000000. DMA zone is 2GB so dma_max_pfn should be 0x87ffff. The incorrect dma_pfn_offset for the USB storage device is because USB devices are not correctly inheriting the dma_pfn_offset from the USB host controller. This will be fixed by a separate patch.

commit ba6dea4f upstream. Whilst MPIDR values themselves are less than 32 bits, it is still perfectly valid for a DT to have #address-cells > 1 in the CPUs node, resulting in the "reg" property having leading zero cell(s). In that situation, the big-endian nature of the data conspires with the current behaviour of only reading the first cell to cause the kernel to think all CPUs have ID 0, and become resoundingly unhappy as a consequence. Take the full property length into account when parsing CPUs so as to be correct under any circumstances. Cc: Russell King <linux@armlinux.org.uk> Signed-off-by:
