2019-01-02perf session: Add comment for perf_session__register_idle_thread()Adrian Hunter1-0/+7
Add a comment to perf_session__register_idle_thread() to bring attention to a pitfall with the idle task thread structure. The pitfall is that there should really be a 'struct thread' for the idle task of each cpu, but there is only one that can have pid == tid == 0.

2019-01-02perf thread-stack: Fix thread stack processing for the idle taskAdrian Hunter5-25/+69
perf creates a single 'struct thread' to represent the idle task. That is because threads are identified by PID and TID, and the idle task always has PID == TID == 0. However, there are actually separate idle tasks for each CPU. That creates a problem for thread stack processing which assumes that each thread has a single stack, not one stack per CPU. Fix that by passing through the CPU number, and in the case of the idle "thread", pick the thread stack from an array based on the CPU number.

2019-01-02thermal: generic-adc: Fix adc to temp interpolationBjorn Andersson1-4/+8
First correct the edge case to return the last element if we're outside the range, rather than at the last element, so that interpolation is not omitted for points between the two last entries in the table. Then correct the formula to perform linear interpolation based the two points surrounding the read ADC value. The indices for temp are kept as "hi" and "lo" to pair with the adc indices, but there's no requirement that the temperature is provided in descendent order. mult_frac() is used to prevent issues with overflowing the int.

2019-01-02thermal: armada: add overheat interrupt supportMiquel Raynal1-1/+269
The IP can manage to trigger interrupts on overheat situation from all the sensors. However, the interrupt source changes along with the last selected source (ie. the last read sensor), which is an inconsistent behavior. Avoid possible glitches by always selecting back only one channel which will then be referenced as the "overheat_sensor" (arbitrarily: the first in the DT which has a critical trip point filled in). It is possible that the scan of all thermal zone nodes did not bring a critical trip point from which the overheat interrupt could be configured. In this case just complain but do not fail the probe. Also disable sensor switch during overheat situations because changing the channel while the system is too hot could clear the overheat state by changing the source while the temperature is still very high. Even if the overheat state is not declared, overheat interrupt must be cleared by reading the DFX interrupt cause _after_ the temperature has fallen down to the low threshold, otherwise future possible interrupts would not be served. A work polls the corresponding register until the overheat flag gets cleared in this case.

2019-01-01PCI: imx: Enable MSI from downstream componentsRichard Zhu1-0/+10
The MSI Enable bit in the MSI Capability (PCIe r4.0, sec 7.7.1.2) controls whether a Function can request service using MSI. i.MX6 Root Ports implement the MSI Capability and may use MSI to request service for events like PME, hotplug, AER, etc. In addition, on i.MX6, the MSI Enable bit controls delivery of MSI interrupts from components below the Root Port. Prior to f3fdfc4ac3a2 ("PCI: Remove host driver Kconfig selection of CONFIG_PCIEPORTBUS"), enabling CONFIG_PCI_IMX6 automatically also enabled CONFIG_PCIEPORTBUS, and when portdrv claimed the Root Ports, it set the MSI Enable bit so it could use PME, hotplug, AER, etc. As a side effect, that also enabled delivery of MSI interrupts from downstream components. The imx6q-pcie driver itself does not depend on portdrv, so set MSI Enable in imx6q-pcie so MSI from downstream components works even if nobody uses MSI for the Root Port events.

2019-01-01KEYS: fix parsing invalid pkey info stringEric Biggers1-0/+2
We need to check the return value of match_token() for Opt_err before doing anything with it. [ Not only did the old "-1" value for Opt_err cause problems for the __test_and_set_bit(), as fixed in commit 94c13f66e13c ("security: don't use a negative Opt_err token index"), but accessing "args[0].from" is invalid for the Opt_err case, as pointed out by Eric later. - Linus ] Reported-by: [email protected] Fixes: 00d60fd3b932 ("KEYS: Provide keyctls to drive the new key type ops for asymmetric keys [ver #2]") Signed-off-by: Eric Biggers <[email protected]> Cc: [email protected] # 4.20 Signed-off-by: Linus Torvalds <[email protected]>
2019-01-01net: hns3: call hns3_nic_net_open() while doing HNAE3_UP_CLIENTHuazhong Tan1-3/+4
For HNAE3_DOWN_CLIENT calling hns3_nic_net_stop(), HNAE3_UP_CLIENT should call hns3_nic_net_open(), since if the number of queue or the map of TC has is changed before HHAE3_UP_CLIENT is called, it will cause problem. Also the HNS3_NIC_STATE_RESETTING flag needs to be cleared before hns3_nic_net_open() called, and set it back while hns3_nic_net_open() failed.

2019-01-01ip: validate header length on virtual device xmitWillem de Bruijn9-32/+66
KMSAN detected read beyond end of buffer in vti and sit devices when passing truncated packets with PF_PACKET. The issue affects additional ip tunnel devices. Extend commit 76c0ddd8c3a6 ("ip6_tunnel: be careful when accessing the inner header") and commit ccfec9e5cb2d ("ip_tunnel: be careful when accessing the inner header"). Move the check to a separate helper and call at the start of each ndo_start_xmit function in net/ipv4 and net/ipv6. Minor changes: - convert dev_kfree_skb to kfree_skb on error path, as dev_kfree_skb calls consume_skb which is not for error paths. - use pskb_network_may_pull even though that is pedantic here, as the same as pskb_may_pull for devices without llheaders. - do not cache ipv6 hdrs if used only once (unsafe across pskb_may_pull, was more relevant to earlier patch) Reported-by: syzbot <[email protected]> Signed-off-by: Willem de Bruijn <[email protected]> Signed-off-by: David S.

2019-01-01tap: call skb_probe_transport_header after setting skb->devWillem de Bruijn1-2/+1
The BPF flow dissector expects either skb->sk or skb->dev set on all skbs. Delay flow dissection until after skb->dev is set. This requires calling from within an rcu read-side critical section. That is fine, see also the call from tun_xdp_one.

2019-01-01ptr_ring: wrap back ->producer in __ptr_ring_swap_queue()Cong Wang1-0/+2
__ptr_ring_swap_queue() tries to move pointers from the old ring to the new one, but it forgets to check if ->producer is beyond the new size at the end of the operation. This leads to an out-of-bound access in __ptr_ring_produce() as reported by syzbot. Reported-by: [email protected] Fixes: 5d49de532002 ("ptr_ring: resize support") Cc: "Michael S.

2019-01-01ALSA: hda - Revert DSP detection on legacy HD-audio driverTakashi Iwai4-116/+8
This essentially reverts the commits c337104b1a16 ("ALSA: HD-Audio: SKL+: abort probe if DSP is present and Skylake driver selected") and d82b51c855a2 ("ALSA: HD-Audio: SKL+: force HDaudio legacy or SKL+ driver selection") for the path of legacy HD-audio controller (snd-hda-intel). The automatic DSP detection and skip of binding with the legacy driver caused regressions on several machines like Dell XPS13. They give the PCI class 0x40380 indicating the availability of DSP while they don't work with ASoC SKL driver (yet). As the support of ASoC driver for such devices isn't available, it's better to revert the whole DSP-detection-and-skip behavior of the legacy driver, so that we can get the old good driver working on such devices. The pci_binding option for ASoC SKL driver is still kept so that it can work without blacklisting.
