[ Upstream commit 9a51c6b1 ] Both acpi_pci_need_resume() and acpi_dev_needs_resume() check if the current ACPI wakeup configuration of the device matches what is expected as far as system wakeup from sleep states is concerned, as reflected by the device_may_wakeup() return value for the device. However, they only should do that if wakeup.flags.valid is set for the device's ACPI companion, because otherwise the wakeup.prepare_count value for it is meaningless. Add the missing wakeup.flags.valid checks to these functions. Signed-off-by:

[ Upstream commit 3f9fbe9b ] Similar to how decrementing rb->next too early can cause data_head to (temporarily) be observed to go backward, so too can this happen when we increment too late. This barrier() ensures the rb->head load happens after the increment, both the one in the 'goto again' path, as the one from perf_output_get_handle() -- albeit very unlikely to matter for the latter.

[ Upstream commit 1b038c6e ] In perf_output_put_handle(), an IRQ/NMI can happen in below location and write records to the same ring buffer: ... local_dec_and_test(&rb->nest) ... <-- an IRQ/NMI can happen here rb->user_page->data_head = head; ... In this case, a value A is written to data_head in the IRQ, then a value B is written to data_head after the IRQ. And A > B. As a result, data_head is temporarily decreased from A to B. And a reader may see data_head < data_tail if it read the buffer frequently enough, which creates unexpected behaviors. This can be fixed by moving dec(&rb->nest) to after updating data_head, which prevents the IRQ/NMI above from updating data_head. [ Split up by peterz. ] Signed-off-by:

[ Upstream commit 2ac44ab6 ] For F17h AMD CPUs, the CPB capability ('Core Performance Boost') is forcibly set, because some versions of that chip incorrectly report that they do not have it. However, a hypervisor may filter out the CPB capability, for good reasons. For example, KVM currently does not emulate setting the CPB bit in MSR_K7_HWCR, and unchecked MSR access errors will be thrown when trying to set it as a guest: unchecked MSR access error: WRMSR to 0xc0010015 (tried to write 0x0000000001000011) at rIP: 0xffffffff890638f4 (native_write_msr+0x4/0x20) Call Trace: boost_set_msr+0x50/0x80 [acpi_cpufreq] cpuhp_invoke_callback+0x86/0x560 sort_range+0x20/0x20 cpuhp_thread_fun+0xb0/0x110 smpboot_thread_fn+0xef/0x160 kthread+0x113/0x130 kthread_create_worker_on_cpu+0x70/0x70 ret_from_fork+0x35/0x40 To avoid this issue, don't forcibly set the CPB capability for a CPU when running under a hypervisor.

[ Upstream commit ccfb62f2 ] The user can change the device_name with the IMSETDEVNAME ioctl, but we need to ensure that the user's name is NUL terminated. Otherwise it could result in a buffer overflow when we copy the name back to the user with IMGETDEVINFO ioctl. I also changed two strcpy() calls which handle the name to strscpy(). Hopefully, there aren't any other ways to create a too long name, but it's nice to do this as a kernel hardening measure. Signed-off-by:

[ Upstream commit b59bd352 ] Currently init_imc_pmu() can fail either because we try to register an IMC unit with an invalid domain (i.e an IMC node not supported by the kernel) or something went wrong while registering a valid IMC unit. In both the cases kernel provides a 'Register failed' error message. For example when trace-imc node is not supported by the kernel, but skiboot advertises a trace-imc node we print: IMC Unknown Device type IMC PMU (null) Register failed To avoid confusion just print the unknown device type message, before attempting PMU registration, so the second message isn't printed.

Given that in all callsites there is a struct net_device pointer available which holds the interface data to be stored in destination register, simplify nft_fib_store_result() to just accept that pointer instead of the nft_pktinfo pointer and interface index.

[ Upstream commit 946c0d8e ] This patch fixes netfilter hook traversal when there are more than 1 hooks returning NF_QUEUE verdict. When the first queue reinjects the packet, 'nf_reinject' starts traversing hooks with a proper hook_index. However, if it again receives a NF_QUEUE verdict (by some other netfilter hook), it queues the packet with a wrong hook_index. So, when the second queue reinjects the packet, it re-executes hooks in between. Fixes: 960632ec ("netfilter: convert hook list to an array") Signed-off-by:

[ Upstream commit 23e3983a ] This patch fixes an bug revealed by the following commit: 6b89d4c1 ("perf/x86/intel: Fix INTEL_FLAGS_EVENT_CONSTRAINT* masking") That patch modified INTEL_FLAGS_EVENT_CONSTRAINT() to only look at the event code when matching a constraint. If code+umask were needed, then the INTEL_FLAGS_UEVENT_CONSTRAINT() macro was needed instead. This broke with some of the constraints for PEBS events. Several of them, including the one used for cycles:p, cycles:pp, cycles:ppp fell in that category and caused the event to be rejected in PEBS mode. In other words, on some platforms a cmdline such as: $ perf top -e cycles:pp would fail with -EINVAL. This patch fixes this bug by properly using INTEL_FLAGS_UEVENT_CONSTRAINT() when needed in the PEBS constraint tables. Reported-by:

[ Upstream commit 1615fe41 ] The MPU6050 driver has recently gained support for the ICM20602 IMU, which is very similar to MPU6xxx. However, the ICM20602's FIFO data specifically includes temperature readings, which were not present on MPU6xxx parts. As a result, the driver will under-read the ICM20602's FIFO register, causing the same (partial) sample to be returned for all reads, until the FIFO overflows. Fix this by adding a table of scan elements specifically for the ICM20602, which takes the extra temperature data into consideration. While we're at it, fix the temperature offset and scaling on ICM20602, since it uses different scale/offset constants than the rest of the MPU6xxx devices. Signed-off-by:

Due to an issue on Spectrum-2, in front-panel ports split four ways, 2 out of 32 port buffers cannot be used. To work around this, the next FW release will mark them as unused, and will report correspondingly lower total shared buffer size. mlxsw will pick up the new value through a query to cap_total_buffer_size resource. However the initial size for shared buffer pool 0 is hard-coded and therefore needs to be updated. Thus reduce the pool size by 2.7 MiB (which corresponds to 2/32 of the total size of 42 MiB), and round down to the whole number of cells.

The cited commit changed the initialization placement of the eswitch attributes so it is done prior to parse tc actions function call, including among others the in_rep and in_mdev fields which are mistakenly reassigned inside the parse actions function. This breaks the source port matching criteria of the peer redirect rule. Fix by removing the now redundant reassignment of the already initialized fields.

After we have a dedicated uplink representor, the new netdev ops doesn't support ndo_set_feature. Because of that, we can't change some features, eg. rxvlan. Now add it back. In this patch, I also do a cleanup for the features flag handling, eg. remove duplicate NETIF_F_HW_TC flag setting.

The driver tries to periodically refresh neighbours that are used to reach nexthops. This is done by periodically calling neigh_event_send(). However, if the neighbour becomes dead, there is nothing we can do to return it to a connected state and the above function call is basically a NOP. This results in the nexthop never being written to the device's adjacency table and therefore never used to forward packets. Fix this by dropping our reference from the dead neighbour and associating the nexthop with a new neigbhour which we will try to refresh.

Add missing entries for create/destroy UCTX and UMEM commands. This could get us wrong "unknown FW command" error in flows where we unbind the device or reset the driver.

[ Upstream commit f0d2ca15 ] Using ethtool, users can specify a classification action matching on the full vlan tag, which includes the DEI bit (also previously called CFI). However, when converting the ethool_flow_spec to a flow_rule, we use dissector keys to represent the matching patterns. Since the vlan dissector key doesn't include the DEI bit, this information was silently discarded when translating the ethtool flow spec in to a flow_rule. This commit adds the DEI bit into the vlan dissector key, and allows propagating the information to the driver when parsing the ethtool flow spec. Fixes: eca4205f ("ethtool: add ethtool_rx_flow_spec to flow_rule structure translator") Reported-by:
