2021-11-10virtio-mem: support VIRTIO_MEM_F_UNPLUGGED_INACCESSIBLEDavid Hildenbrand2-3/+7
The initial virtio-mem spec states that while unplugged memory should not be read, the device still has to allow for reading unplugged memory inside the usable region. The primary motivation for this default handling was to simplify bringup of virtio-mem, because there were corner cases where Linux might have accidentially read unplugged memory inside added Linux memory blocks. In the meantime, we: 1. Removed /dev/kmem in commit bbcd53c96071 ("drivers/char: remove /dev/kmem for good") 2. Disallowed access to virtio-mem device memory via /dev/mem in commit 2128f4e21aa2 ("virtio-mem: disallow mapping virtio-mem memory via /dev/mem") 3. Sanitized access to virtio-mem device memory via /proc/kcore in commit 0daa322b8ff9 ("fs/proc/kcore: don't read offline sections, logically offline pages and hwpoisoned pages") 4. Sanitized access to virtio-mem device memory via /proc/vmcore in commit ce2814622e84 ("virtio-mem: kdump mode to sanitize /proc/vmcore access") "Accidential" access to unplugged memory is no longer possible; we can support the new VIRTIO_MEM_F_UNPLUGGED_INACCESSIBLE feature that will be required by some hypervisors implementing virtio-mem in the near future.

2021-11-10selftests: net: test_vxlan_under_vrf: fix HV connectivity testAndrea Righi1-0/+2
It looks like test_vxlan_under_vrf.sh is always failing to verify the connectivity test during the ping between the two simulated VMs. This is due to the fact that veth-hv in each VM should have a distinct MAC address. Fix by setting a unique MAC address on each simulated VM interface. Without this fix: $ sudo ./tools/testing/selftests/net/test_vxlan_under_vrf.sh Checking HV connectivity [ OK ] Check VM connectivity through VXLAN (underlay in the default VRF) [FAIL] With this fix applied: $ sudo ./tools/testing/selftests/net/test_vxlan_under_vrf.sh Checking HV connectivity [ OK ] Check VM connectivity through VXLAN (underlay in the default VRF) [ OK ] Check VM connectivity through VXLAN (underlay in a VRF) [FAIL] NOTE: the connectivity test with the underlay VRF is still failing; it seems that ARP requests are blocked at the simulated hypervisor level, probably due to some missing ARP forwarding rules.

2021-11-10net: hns3: sync rx ring head in echo common pullYufeng Mo5-0/+50
When the driver processes rx packets, the head pointer is updated only after the number of received packets reaches 16. However, hardware relies on the head pointer to calculate the number of FBDs. As a result, the hardware calculates the FBD incorrectly. Therefore, the driver proactively updates the head pointer in each common poll to ensure that the number of FBDs calculated by the hardware is correct.

Currently, driver will send command to firmware to query pfc packet number when user uses dcb tool to get pfc parameters. However, the periodic service task will also periodically query and record MAC statistics, including pfc packet number. As the hardware registers of statistics is cleared after reading, it will cause pfc packet number of MAC statistics are not correct after using dcb tool to get pfc parameters. To fix this problem, when user uses dcb tool to get pfc parameters, driver updates MAC statistics firstly and then get pfc packet number from MAC statistics.

2021-11-10net: hns3: fix failed to add reuse multicast mac addr to hardware when mc ↵Guangbin Huang1-23/+27
mac table is full Currently, when driver is failed to add a new multicast mac address to hardware due to the multicast mac table is full, it will directly return. In this case, if the multicast mac list has some reuse addresses after the new address, those reuse addresses will never be added to hardware. To fix this problem, if function hclge_add_mc_addr_common() returns -ENOSPC, hclge_sync_vport_mac_list() should judge whether continue or stop to add next address. As function hclge_sync_vport_mac_list() needs parameter mac_type to know whether is uc or mc, refine this function to add parameter mac_type and remove parameter sync. So does function hclge_unsync_vport_mac_list(). Fixes: ee4bcd3b7ae4 ("net: hns3: refactor the MAC address configure") Signed-off-by: Guangbin Huang <[email protected]> Signed-off-by: David S.

Modern devices may redraw display at 60 Hz, make sure we have one input sample per one frame. Reduce sample period to 15ms, so we would get up to 66.6 samples per second, although realistically with all the jitter and extra scheduling wiggle room, we would end up just above 60 samples per second. This should be a good compromise between sampling too often and sampling too seldom.

2021-11-09Input: ili210x - improve polled sample spacingMarek Vasut1-2/+8
Currently the ili210x driver implements a threaded interrupt handler which starts upon edge on the interrupt line, and then polls the touch controller for samples. Every time a sample is obtained from the controller, the thread function checks whether further polling is required, and if so, waits fixed amount of time before polling for next sample. The delay between consecutive samples can thus vary greatly, because the I2C transfer required to retrieve the sample from the controller takes different amount of time on different platforms. Furthermore, different models of the touch controllers supported by this driver require different delays during retrieval of samples too. Instead of waiting fixed amount of time before polling for next sample, determine how much time passed since the beginning of sampling cycle and then wait only the remaining amount of time within the sampling cycle. This makes the driver deliver samples with equal spacing between them.

With commit 506c1da44fee ("cifs: use the expiry output of dns_query to schedule next resolution") and after triggering the first reconnect, the next async dns resolution of tcp server's hostname would be scheduled based on dns_resolver's key expiry default, which happens to default to 5s on most systems that use key.dns_resolver for upcall.

2021-11-09amt: use cancel_delayed_work() instead of flush_delayed_work() in amt_fini()Taehee Yoo1-1/+1
When the amt module is being removed, it calls flush_delayed_work() to exit source_gc_wq. But it wouldn't be exited properly because the amt_source_gc_work(), which is the callback function of source_gc_wq internally calls mod_delayed_work() again. So, amt_source_gc_work() would be called after the amt module is removed. Therefore kernel panic would occur. In order to avoid it, cancel_delayed_work() should be used instead of flush_delayed_work().

2021-11-10rtc: ab8500: let the core handle the alarm resolutionAlexandre Belloni1-19/+4
Tell the RTC core UIE are not supported because the resolution of the alarm is a minute. Note that this is in fact also fixing how the resolution is reported as the previous test was simply ensuring the alarm was more than a minute in the future while the register has a minute resolution. This would be ok if the alarm was a countdown but ab8500_rtc_read_alarm suggests otherwise and the AB8500 datasheet states that the RTC documentation is not public. Finally, the comment is wrong and what makes the UIE emulation work is uie_unsupported being set.
