2017-10-31Drivers: hv: vmbus: Make panic reporting to be more usefulK. Y. Srinivasan1-2/+2
Hyper-V allows the guest to report panic and the guest can pass additional information. All this is logged on the host. Currently Linux is passing back information that is not particularly useful. Make the following changes: 1. Windows uses crash MSR P0 to report bugcheck code. Follow the same convention for Linux as well. 2. It will be useful to know the gust ID of the Linux guest that has paniced. Pass back this information. These changes will help in better supporting Linux on Hyper-V Signed-off-by: K. Y.

2017-10-23genwqe: Take R/W permissions into account when dealing with memory pagesGuilherme G. Piccoli3-18/+38
Currently we assume userspace pages are always writable when doing memory pinning. This is not true, specially since userspace applications may allocate their memory the way they want, we have no control over it. If a read-only page is set for pinning, currently the driver fails due to get_user_pages_fast() refusing to map read-only pages as writable. This patch changes this behavior, by taking the permission flags of the pages into account in both pinning/unpinning process, as well as in the DMA data copy-back to userpace (which we shouldn't try to do blindly, since it will fail in case of read-only-pages).

2017-10-22stmmac: Don't access tx_q->dirty_tx before netif_tx_lockBernd Edlinger1-1/+2
This is the possible reason for different hard to reproduce problems on my ARMv7-SMP test system. The symptoms are in recent kernels imprecise external aborts, and in older kernels various kinds of network stalls and unexpected page allocation failures. My testing indicates that the trouble started between v4.5 and v4.6 and prevails up to v4.14. Using the dirty_tx before acquiring the spin lock is clearly wrong and was first introduced with v4.6.

2017-10-22of_mdio: Fix broken PHY IRQ in case of probe deferralGeert Uytterhoeven1-12/+27
If an Ethernet PHY is initialized before the interrupt controller it is connected to, a message like the following is printed: irq: no irq domain found for /interrupt-controller@e61c0000 ! However, the actual error is ignored, leading to a non-functional (POLL) PHY interrupt later: Micrel KSZ8041RNLI ee700000.ethernet-ffffffff:01: attached PHY driver [Micrel KSZ8041RNLI] (mii_bus:phy_addr=ee700000.ethernet-ffffffff:01, irq=POLL) Depending on whether the PHY driver will fall back to polling, Ethernet may or may not work. To fix this: 1. Switch of_mdiobus_register_phy() from irq_of_parse_and_map() to of_irq_get(). Unlike the former, the latter returns -EPROBE_DEFER if the interrupt controller is not yet available, so this condition can be detected. Other errors are handled the same as before, i.e. use the passed mdio->irq[addr] as interrupt. 2. Propagate and handle errors from of_mdiobus_register_phy() and of_mdiobus_register_device().

2017-10-21net: aquantia: Bad udp rate on default interrupt coalescingIgor Russkikh1-6/+6
Default Tx rates cause very long ISR delays on Tx. 0xff is 510us delay, giving only ~ 2000 interrupts per seconds for Tx rings cleanup. With these settings udp tx rate was never higher than ~800Mbps on a single stream. Changing min delay to 0xF makes it way better with ~6Gbps TCP stream performance is almost unaffected by this change, since LSO optimizations play important role. CPU load is affected insignificantly by this change. Signed-off-by: Pavel Belous <pavel.belous@aquantia.com> Signed-off-by: Igor Russkikh <igor.russkikh@aquantia.com> Signed-off-by: David S.

2017-10-21net: aquantia: Reset nic statistics on interface up/downIgor Russkikh6-17/+75
Internal statistics system on chip never gets reset until hardware reboot. This is quite inconvenient in terms of ethtool statistics usage. This patch implements incremental statistics update inside of service callback. Upon nic initialization, first request is done to fetch initial stat data, current collected stat data gets cleared. Internal statistics mailbox readout is improved to save space and increase readability Signed-off-by: Pavel Belous <pavel.belous@aquantia.com> Signed-off-by: Igor Russkikh <igor.russkikh@aquantia.com> Signed-off-by: David S.

2017-10-21android: binder: Don't get mm from taskSherry Yang2-14/+9
Use binder_alloc struct's mm_struct rather than getting a reference to the mm struct through get_task_mm to avoid a potential deadlock between lru lock, task lock and dentry lock, since a thread can be holding the task lock and the dentry lock while trying to acquire the lru lock.

2017-10-21geneve: Fix function matching VNI and tunnel ID on big-endianStefano Brivio1-6/+0
On big-endian machines, functions converting between tunnel ID and VNI use the three LSBs of tunnel ID storage to map VNI. The comparison function eq_tun_id_and_vni(), on the other hand, attempted to map the VNI from the three MSBs. Fix it by using the same check implemented on LE, which maps VNI from the three LSBs of tunnel ID. Fixes: 2e0b26e10352 ("geneve: Optimize geneve device lookup.")

git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can Marc Kleine-Budde says: ==================== pull-request: can 2017-10-19 this is a pull request of 11 patches for the upcoming 4.14 release. There are 6 patches by ZHU Yi for the flexcan driver, that work around the CAN error handling state transition problems found in various incarnations of the flexcan IP core. The patch by Colin Ian King fixes a potential NULL pointer deref in the CAN broad cast manager (bcm). One patch by me replaces a direct deref of a RCU protected pointer by rcu_access_pointer. My second patch adds missing OOM error handling in af_can. A patch by Stefan Mätje for the esd_usb2 driver fixes the dlc in received RTR frames. And the last patch is by Wolfgang Grandegger, it fixes a busy loop in the gs_usb driver in case it runs out of TX contexts. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
