Refer to the databook of DesignWare Cores Ethernet MAC Universal: 6.2.1.5 Register 4 (Transmit Descriptor List Address Register If this register is not changed when the ST bit is set to 0, then the DMA takes the descriptor address where it was stopped earlier. The stmmac_tx_err() does zero indices to Tx descriptors, but does not reset HW current Tx descriptor address. To fix inconsistency, the base address of the Tx descriptors should be rewritten before restarting Tx. Signed-off-by: Jongsung Kim <neidhard.kim@lge.com> Signed-off-by: David S.

2019-12-06enetc: disable EEE autoneg by defaultYangbo Lu
The EEE support has not been enabled on ENETC, but it may connect to a PHY which supports EEE and advertises EEE by default, while its link partner also advertises EEE. If this happens, the PHY enters low power mode when the traffic rate is low and causes packet loss. This patch disables EEE advertisement by default for any PHY that ENETC connects to, to prevent the above unwanted outcome.

2019-12-05net: hns3: fix a use after free problem in hns3_nic_maybe_stop_tx()Yunsheng Lin
Currently, hns3_nic_maybe_stop_tx() uses skb_copy() to linearize a SKB if the BD num required by the SKB does not meet the hardware limitation, and it linearizes the SKB by allocating a new linearized SKB and freeing the old SKB, if hns3_nic_maybe_stop_tx() returns -EBUSY because there are no enough space in the ring to send the linearized skb to hardware, the sch_direct_xmit() still hold reference to old SKB and try to retransmit the old SKB when dev_hard_start_xmit() return TX_BUSY, which may cause use after freed problem. This patch fixes it by using __skb_linearize() to linearize the SKB in hns3_nic_maybe_stop_tx().

There is timing window between ring_space checking and netif_stop_subqueue when transmiting a SKB, and the TX BD cleaning may be executed during the time window, which may caused TX queue not restarted problem. This patch fixes it by rechecking the ring_space after netif_stop_subqueue to make sure TX queue is restarted. Also, the ring->next_to_clean is updated even when pkts is zero, because all the TX BD cleaned may be non-SKB, so it needs to check if TX queue need to be restarted.

2019-12-05s390/qeth: fix dangling IO buffers after halt/clearJulian Wiedmann
The cio layer's intparm logic does not align itself well with how qeth manages cmd IOs. When an active IO gets terminated via halt/clear, the corresponding IRQ's intparm does not reflect the cmd buffer but rather the intparm that was passed to ccw_device_halt() / ccw_device_clear(). This behaviour was recently clarified in commit b91d9e67e50b ("s390/cio: fix intparm documentation"). As a result, qeth_irq() currently doesn't cancel a cmd that was terminated via halt/clear. This primarily causes us to leak card->read_cmd after the qeth device is removed, since our IO path still holds a refcount for this cmd. For qeth this means that we need to keep track of which IO is pending on a device ('active_cmd'), and use this as the intparm when calling halt/clear. Otherwise qeth_irq() can't match the subsequent IRQ to its cmd buffer. Since we now keep track of the _expected_ intparm, we can also detect any mismatch; this would constitute a bug somewhere in the lower layers. In this case cancel the active cmd - we effectively "lost" the IRQ and should not expect any further notification for this IO.

2019-12-05s390/qeth: ensure linear access to packet headersJulian Wiedmann
When the RX path builds non-linear skbs, the packet headers can currently spill over into page fragments. Depending on the packet type and what fields we need to access in the headers, this could cause us to go past the end of skb->data. So for non-linear packets, copy precisely the length of the necessary headers ('linear_len') into skb->data. And don't copy more, upper-level protocols will peel whatever additional packet headers they need.

2019-12-05s390/qeth: guard against runt packetsJulian Wiedmann
Depending on a packet's type, the RX path needs to access fields in the packet headers and thus requires a minimum packet length. Enforce this length when building the skb. On the other hand a single runt packet is no reason to drop the whole RX buffer. So just skip it, and continue processing on the next packet.

2019-12-04net: ipv6_stub: use ip6_dst_lookup_flow instead of ip6_dst_lookupSabrina Dubroca
ipv6_stub uses the ip6_dst_lookup function to allow other modules to perform IPv6 lookups. However, this function skips the XFRM layer entirely. All users of ipv6_stub->ip6_dst_lookup use ip_route_output_flow (via the ip_route_output_key and ip_route_output helpers) for their IPv4 lookups, which calls xfrm_lookup_route(). This patch fixes this inconsistent behavior by switching the stub to ip6_dst_lookup_flow, which also calls xfrm_lookup_route(). This requires some changes in all the callers, as these two functions take different arguments and have different return types.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v5.5 kernel cycle Core changes: - Expose pull up/down flags for the GPIO character device to userspace. After clear input from the RaspberryPi and Beagle communities, it has been established that prototyping, industrial automation and make communities strongly need this feature, and as we want people to use the character device, we have implemented the simple pull up/down interface for GPIO lines. This means we can specify that a (chip-specific) pull up/down resistor can be enabled, but does not offer fine-grained control such as cases where the resistance of the same pull resistor can be controlled (yet). - Introduce devm_fwnode_gpiod_get_index() and start to phase out the old symbol devm_fwnode_get_index_gpiod_from_child(). - A bit of documentation clean-up work. - Introduce a define for GPIO line directions and deploy it in all GPIO drivers in the drivers/gpio directory. - Add a special callback to populate pin ranges when cooperating with the pin control subsystem and registering ranges as part of adding a gpiolib driver and a gpio_irq_chip driver at the same time. This is also deployed in the Intel Merrifield driver. New drivers: - RDA Micro GPIO controller. - XGS-iproc GPIO driver.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This merge window we have one small clk provider API in the core framework and then a bunch of driver updates and a handful of new drivers. In terms of diffstat the Qualcomm and Amlogic drivers are high up there because of all the clk data introcued by new drivers. The Nvidia Tegra driver had a lot of work done this cycle too to support suspend/resume and memory controllers. And the OMAP clk driver got proper clk and reset handling in place. Rounding out the patches are various updates to remove unused data, mark things static, correct incorrect data in drivers, etc. All the little things that improve drivers and maintain code health. I will point out that there's a patch in here for the GPIO clk driver, that almost nobody uses, which changes behavior and causes clk_set_rate() to try to change the GPIO gate clk's parent. Other than that things are fairly well SoC specific here.

2019-12-01net: phy: realtek: fix using paged operations with RTL8105e / RTL8208Heiner Kallweit
It was reported [0] that since the referenced commit a warning is triggered in phylib that complains about paged operations being used with a PHY driver that doesn't support this. The commit isn't wrong, just for one chip version (RTL8105e) no dedicated PHY driver exists yet. So add the missing PHY driver.

It was reported [0] that network doesn't wake up on cable plug-in with certain chip versions. Reason is that on these chip versions the PHY doesn't detect cable plug-in when being in power-down mode.

2019-12-01drivers/base/memory.c: drop the mem_sysfs_mutexDavid Hildenbrand
The mem_sysfs_mutex isn't really helpful. Also, it's not really clear what the mutex protects at all. The device lists of the memory subsystem are protected separately. We don't need that mutex when looking up. creating, or removing independent devices. find_memory_block_by_id() will perform locking on its own and grab a reference of the returned device. At the time memory_dev_init() is called, we cannot have concurrent hot(un)plug operations yet - we're still fairly early during boot. We don't need any locking. The creation/removal of memory block devices should be protected on a higher level - especially using the device hotplug lock to avoid documented issues (see Documentation/core-api/memory-hotplug.rst) - or if that is reworked, using similar locking. Protecting in the context of these functions only doesn't really make sense. Especially, if we would have a situation where the same memory blocks are created/deleted at the same time, there is something horribly going wrong (imagining adding/removing a DIMM at the same time from two call paths) - after the functions succeeded something else in the callers would blow up (e.g., create_memory_block_devices() succeeded but there are no memory block devices anymore). All relevant call paths (except when adding memory early during boot via ACPI, which is now documented) hold the device hotplug lock when adding memory, and when removing memory. Let's document that instead. Add a simple safety net to create_memory_block_devices() in case we would actually remove memory blocks while adding them, so we'll never dereference a NULL pointer. Simplify memory_dev_init() now that the lock is gone.
