2021-03-24x86/Hyper-V: Support for free page reportingSunil Muthuswamy
Linux has support for free page reporting now (36e66c554b5c) for virtualized environment. On Hyper-V when virtually backed VMs are configured, Hyper-V will advertise cold memory discard capability, when supported. This patch adds the support to hook into the free page reporting infrastructure and leverage the Hyper-V cold memory discard hint hypercall to report/free these pages back to the host.

When xfrm interfaces are used in combination with namespaces and ESP offload, we get a dst_entry NULL pointer dereference. This is because we don't have a dst_entry attached in the ESP offloading case and we need to do a policy lookup before the namespace transition.

2021-03-24xfrm: BEET mode doesn't support fragments for inner packetsXin Long
BEET mode replaces the IP(6) Headers with new IP(6) Headers when sending packets. However, when it's a fragment before the replacement, currently kernel keeps the fragment flag and replace the address field then encaps it with ESP. It would cause in RX side the fragments to get reassembled before decapping with ESP, which is incorrect. In Xiumei's testing, these fragments went over an xfrm interface and got encapped with ESP in the device driver, and the traffic was broken. I don't have a good way to fix it, but only to warn this out in dmesg.

2021-03-23net: bridge: don't notify switchdev for local FDB addressesVladimir Oltean
As explained in this discussion: https://lore.kernel.org/netdev/20210117193009.io3nungdwuzmo5f7@skbuf/ the switchdev notifiers for FDB entries managed to have a zero-day bug. The bridge would not say that this entry is local: ip link add br0 type bridge ip link set swp0 master br0 bridge fdb add dev swp0 00:01:02:03:04:05 master local and the switchdev driver would be more than happy to offload it as a normal static FDB entry. This is despite the fact that 'local' and non-'local' entries have completely opposite directions: a local entry is locally terminated and not forwarded, whereas a static entry is forwarded and not locally terminated. So, for example, DSA would install this entry on swp0 instead of installing it on the CPU port as it should. There is an even sadder part, which is that the 'local' flag is implicit if 'static' is not specified, meaning that this command produces the same result of adding a 'local' entry: bridge fdb add dev swp0 00:01:02:03:04:05 master I've updated the man pages for 'bridge', and after reading it now, it should be pretty clear to any user that the commands above were broken and should have never resulted in the 00:01:02:03:04:05 address being forwarded (this behavior is coherent with non-switchdev interfaces): https://patchwork.kernel.org/project/netdevbpf/cover/20210211104502.2081443-1-olteanv@gmail.com/ If you're a user reading this and this is what you want, just use: bridge fdb add dev swp0 00:01:02:03:04:05 master static Because switchdev should have given drivers the means from day one to classify FDB entries as local/non-local, but didn't, it means that all drivers are currently broken. So we can just as well omit the switchdev notifications for local FDB entries, which is exactly what this patch does to close the bug in stable trees. For further development work where drivers might want to trap the local FDB entries to the host, we can add a 'bool is_local' to br_switchdev_fdb_call_notifiers(), and selectively make drivers act upon that bit, while all the others ignore those entries if the 'is_local' bit is set.

2021-03-23net/sched: act_ct: clear post_ct if doing ct_clearMarcelo Ricardo Leitner
Invalid detection works with two distinct moments: act_ct tries to find a conntrack entry and set post_ct true, indicating that that was attempted. Then, when flow dissector tries to dissect CT info and no entry is there, it knows that it was tried and no entry was found, and synthesizes/sets key->ct_state = TCA_FLOWER_KEY_CT_FLAGS_TRACKED | TCA_FLOWER_KEY_CT_FLAGS_INVALID; mimicing what OVS does. OVS has this a bit more streamlined, as it recomputes the key after trying to find a conntrack entry for it. Issue here is, when we have 'tc action ct clear', it didn't clear post_ct, causing a subsequent match on 'ct_state -trk' to fail, due to the above. The fix, thus, is to clear it. Reproducer rules: tc filter add dev enp130s0f0np0_0 ingress prio 1 chain 0 \ protocol ip flower ip_proto tcp ct_state -trk \ action ct zone 1 pipe \ action goto chain 2 tc filter add dev enp130s0f0np0_0 ingress prio 1 chain 2 \ protocol ip flower \ action ct clear pipe \ action goto chain 4 tc filter add dev enp130s0f0np0_0 ingress prio 1 chain 4 \ protocol ip flower ct_state -trk \ action mirred egress redirect dev enp130s0f1np1_0 With the fix, the 3rd rule matches, like it does with OVS kernel datapath.

2021-03-23PM: EM: postpone creating the debugfs dir till fs_initcallLukasz Luba
The debugfs directory '/sys/kernel/debug/energy_model' is needed before the Energy Model registration can happen. With the recent change in debugfs subsystem it's not allowed to create this directory at early stage (core_initcall). Thus creating this directory would fail. Postpone the creation of the EM debug dir to later stage: fs_initcall. It should be safe since all clients: CPUFreq drivers, Devfreq drivers will be initialized in later stages. The custom debug log below prints the time of creation the EM debug dir at fs_initcall and successful registration of EMs at later stages.

2021-03-23arm64: tegra: Set fw_devlink=on for Jetson TX2Jon Hunter
Commit 5d25c476f252 ("Revert "arm64: tegra: Disable the ACONNECT for Jetson TX2"") re-enabled the Tegra ADMA and ACONNECT drivers to support audio on Jetson TX2. However, this revert was dependent upon commit e590474768f1 ("driver core: Set fw_devlink=on by default") and without this commit, enabling the ACONNECT is causing resume from system suspend to fail on Jetson TX2. Resume fails because the ACONNECT driver is being resumed before the BPMP driver, and the ACONNECT driver is attempting to power on a power-domain that is provided by the BPMP. Commit e590474768f1 ("driver core: Set fw_devlink=on by default") has since been temporarily reverted while some issues are being investigated. This is causing resume from system suspend on Jetson TX2 to fail again. Rather than disable the ACONNECT driver again, fix this by setting fw_devlink is set to 'on' for Jetson TX2 in the bootargs specified in device-tree.

2021-03-23Input: nspire-keypad - enable interrupts only when openedFabian Vogt
The driver registers an interrupt handler in _probe, but didn't configure them until later when the _open function is called. In between, the keypad can fire an IRQ due to touchpad activity, which the handler ignores. This causes the kernel to disable the interrupt, blocking the keypad from working. Fix this by disabling interrupts before registering the handler. Additionally, disable them in _close, so that they're only enabled while open.

The input MCLK is 12.288MHz, the desired output sysclk is 11.2896MHz and sample rate is 44100Hz, with the configuration pllprescale=2, postscale=sysclkdiv=1, some chip may have wrong bclk and lrclk output with pll enabled in master mode, but with the configuration pllprescale=1, postscale=2, the output clock is correct. >From Datasheet, the PLL performs best when f2 is between 90MHz and 100MHz when the desired sysclk output is 11.2896MHz or 12.288MHz, so sysclkdiv = 2 (f2/8) is the best choice.

2021-03-23block: recalculate segment count for multi-segment discards correctlyDavid Jeffery
When a stacked block device inserts a request into another block device using blk_insert_cloned_request, the request's nr_phys_segments field gets recalculated by a call to blk_recalc_rq_segments in blk_cloned_rq_check_limits. But blk_recalc_rq_segments does not know how to handle multi-segment discards. For disk types which can handle multi-segment discards like nvme, this results in discard requests which claim a single segment when it should report several, triggering a warning in nvme and causing nvme to fail the discard from the invalid state.

This check fails if the compiler is not explicitly specified, so reverts to the standard "cc", in which case --version doesn't mention the "gcc" string we match against: $ cc --version | head -n 1 cc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0 This will not add the -march switch to the command line, so compilation fails: mte_helper.S: Assembler messages: mte_helper.S:25: Error: selected processor does not support `irg x0,x0,xzr' mte_helper.S:38: Error: selected processor does not support `gmi x1,x0,xzr' ... Actually clang accepts the same -march option as well, so we can just drop this check and add this unconditionally to the command line, to avoid any future issues with this check altogether (gcc actually prints basename(argv[0]) when called with --version).
