[ Upstream commit 7a717122 ] dmesg reports that "Your touchpad (PNP: SYN3052 SYN0100 SYN0002 PNP0f13) says it can support a different bus." I've tested the offered psmouse.synaptics_intertouch=1 with 4.18.x and 4.19.x and it seems to work well. No problems seen with suspend/resume. Also, it appears that RMI/SMBus mode is actually required for 3-4 finger multitouch gestures to work -- otherwise they are not reported at all. Information from dmesg in both modes: psmouse serio3: synaptics: Touchpad model: 1, fw: 8.2, id: 0x1e2b1, caps: 0xf00123/0x840300/0x2e800/0x0, board id: 3139, fw id: 2000742 psmouse serio3: synaptics: Trying to set up SMBus access rmi4_smbus 6-002c: registering SMbus-connected sensor rmi4_f01 rmi4-00.fn01: found RMI device, manufacturer: Synaptics, product: TM3139-001, fw id: 2000742 Signed-off-by:

[ Upstream commit c8da642d ] The gpio IP on Armada 370 at offset 0x18180 has neither a clk nor pwm registers. So there is no need for a clk as the pwm isn't used anyhow. So only check for the clk in the presence of the pwm registers. This fixes a failure to probe the gpio driver for the above mentioned gpio device.

[ Upstream commit ef7cfd00 ] For the same reason as commit 25896d07 ("x86/build: Fix compiler support check for CONFIG_RETPOLINE"), you cannot put this $(error ...) into the parse stage of the top Makefile. Perhaps I'd propose a more sophisticated solution later, but this is the best I can do for now. Link: https://lkml.org/lkml/2017/12/25/211Reported-by:

[ Upstream commit 34b1e0e9 ] mac80211 uses the frag list to build AMSDU. When freeing the skb, it may not be really freed, since someone is still holding a reference to it. In that case, when TCP skb is being retransmitted, the pointer to the frag list is being reused, while the data in there is no longer valid. Since we will never get frag list from the network stack, as mac80211 doesn't advertise the capability, we can safely free and nullify it before releasing the SKB. Signed-off-by:

[ Upstream commit f7db2beb ] Currently variable data0 is not being initialized so a garbage value is being passed to vxge_hw_vpath_fw_api and this value is being written to the rts_access_steer_data0 register. There are other occurrances where data0 is being initialized to zero (e.g. in function vxge_hw_upgrade_read_version) so I think it makes sense to ensure data0 is initialized likewise to 0.

[ Upstream commit 15515aaa ] Current state for the lan78xx driver does not allow for changing the MAC address of the interface, without either removing the module (if you compiled it that way) or rebooting the machine. If you attempt to change the MAC address, ifconfig will show the new address, however, the system/interface will not respond to any traffic using that configuration. A few short-term options to work around this are to unload the module and reload it with the new MAC address, change the interface to "promisc", or reboot with the correct configuration to change the MAC. This patch enables the ability to change the MAC address via fairly normal means... ifdown <interface> modify entry in /etc/network/interfaces OR a similar method ifup <interface> Then test via any network communication, such as ICMP requests to gateway. My only test platform for this patch has been a raspberry pi model 3b+. Signed-off-by:

[ Upstream commit 8159ecab ] Bit RX_USED set to 0 in the address field allows the controller to write data to the receive buffer descriptor. The driver does not ensure the ctrl field is ready (cleared) when the controller sees the RX_USED=0 written by the driver. The ctrl field might only be cleared after the controller has already updated it according to a newly received frame, causing the frame to be discarded in gem_rx() due to unexpected ctrl field contents. A message is logged when the above scenario occurs: macb ff0b0000.ethernet eth0: not whole frame pointed by descriptor Fix the issue by ensuring that when the controller sees RX_USED=0 the ctrl field is already cleared. This issue was observed on a ZynqMP based system. Fixes: 4df95131 ("net/macb: change RX path for GEM") Signed-off-by:

[ Upstream commit e100a897 ] 64-bit DMA addresses are split in upper and lower halves that are written in separate fields on GEM. For RX, bit 0 of the address is used as the ownership bit (RX_USED). When the RX_USED bit is unset the controller is allowed to write data to the buffer. The driver does not guarantee that the controller already sees the upper half when the RX_USED bit is cleared, possibly resulting in the controller writing an incoming frame to an address with an incorrect upper half and therefore possibly corrupting unrelated system memory. Fix that by adding the necessary DMA memory barrier between the writes. This corruption was observed on a ZynqMP based system.

[ Upstream commit 6adafc35 ] Create a net bridge, add eth and vnet to the bridge. The vnet is used by a virtual machine. When ping the virtual machine from the outside host and the virtual machine send multicast at the same time, the ping package will lost. The multicast package send to the eth, eth will send it to the bridge too, and the bridge learn the mac of eth. When outside host ping the virtual mechine, it will match the promisc entry of the eth which is not expected, and the bridge send it to eth not to vnet, cause ping lost. So this patch change promisc tcam entry position to the END of 512 tcam entries, which indicate lower priority. And separate one promisc entry to two: mc & uc, to avoid package match the wrong tcam entry. Signed-off-by:

[ Upstream commit 308c6caf ] There are two test cases: 1. Remove the 4 modules:hns_enet_drv/hns_dsaf/hnae/hns_mdio, and install them again, must use "ifconfig down/ifconfig up" command pair to bring port to work. This patch calls phy_stop function when init phy to fix this bug. 2. Remove the 2 modules:hns_enet_drv/hns_dsaf, and install them again, all ports can not use anymore, because of the phy devices register failed(phy devices already exists). Phy devices are registered when hns_dsaf installed, this patch removes them when hns_dsaf removed.

[ Upstream commit 16877a55 ] There is a guard hole at the beginning of the kernel address space, also used by hypervisors. It occupies 16 PGD entries. This reserved range is not defined explicitely, it is calculated relative to other entities: direct mapping and user space ranges. The calculation got broken by recent changes of the kernel memory layout: LDT remap range is now mapped before direct mapping and makes the calculation invalid. The breakage leads to crash on Xen dom0 boot[1]. Define the reserved range explicitely. It's part of kernel ABI (hypervisors expect it to be stable) and must not depend on changes in the rest of kernel memory layout.

[ Upstream commit ca504728 ] Before commit 7fd6d98b ("i2c: i801: Allow ACPI AML access I/O ports not reserved for SMBus"), enabling RMI on the T560 would cause the touchpad to stop working after resuming from suspend. Now that this issue is fixed, RMI can be enabled safely and works fine. Reviewed-by:

[ Upstream commit e2ca26ec ] With PM enabled, I noticed that pressing a key on the droid4 keyboard will block deeper idle states for the SoC. Let's fix this by using IRQF_ONESHOT and stop constantly toggling the device OMAP4_KBD_IRQENABLE register as suggested by Dmitry Torokhov <dmitry.torokhov@gmail.com>. From the hardware point of view, looks like we need to manage the registers for OMAP4_KBD_IRQENABLE and OMAP4_KBD_WAKEUPENABLE together to avoid blocking deeper SoC idle states. And with toggling of OMAP4_KBD_IRQENABLE register now gone with IRQF_ONESHOT, also the SoC idle state problem is gone during runtime. We still also need to clear OMAP4_KBD_WAKEUPENABLE in omap4_keypad_close() though to pair it with omap4_keypad_open() to prevent blocking deeper SoC idle states after rmmod omap4-keypad. Reported-by:

[ Upstream commit 530aad77 ] When adjusting sack block sequence numbers, skb_make_writable() gets called to make sure tcp options are all in the linear area, and buffer is not shared. This can cause tcp header pointer to get reallocated, so we must reaload it to avoid memory corruption. This bug pre-dates git history. Reported-by:
