BugLink: https://bugs.launchpad.net/bugs/1878232 commit 65ee6708 upstream. The current implementation does not handle timeout in case of command with callback request, and this can lead to deadlock if the command doesn't get fw response. Add delayed callback timeout work before posting the command to fw. In case of real fw command completion we will cancel the delayed work. In case of fw command timeout the callback timeout handler will be called and it will simulate fw completion with timeout error.

BugLink: https://bugs.launchpad.net/bugs/1878232 commit d57847dc upstream. The device ID for VFs is in a different location than PFs. This results in the poll always timing out for VFs. There's no good way to read the VF device ID without using the PF's configuration space. Switch to waiting for the health poll to start incrementing.

BugLink: https://bugs.launchpad.net/bugs/1878232 commit c1d4d2e9 upstream. In internal error state the health poll thread will eventually call synchronize_irq() (to safely trigger command completions) which might sleep, so we are calling sleeping function from atomic context which is invalid. Here we move trigger_cmd_completions(dev) to enter error state which is the earliest stage in error state handling. This way we won't need to wait for next health poll to trigger command completions and will solve the scheduling while atomic issue. mlx5_enter_error_state can be called from two contexts, protect it with dev->intf_state_lock Fixes: 89d44f0a ('net/mlx5_core: Add pci error handlers to mlx5_core driver') Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1878232 commit 0ca00fc1 upstream. Blue flame is a latency enhancement feature that allows the driver to write the packet data directly to the NIC's registers thus making the read of the packet data from host memory redundant. We maintain a quota for the blue flame which is reloaded whenever we identify that the hardware is processing send requests and processes them fast enough so by the time we post the next send request it was able to process all the pending ones. This indicates that the hardware is capable of processing more blue flame requests efficiently. The blue flame quota is decremented whenever we send using blue flame. The current code erroneously clears the budget if we did not use blue flame for the current post send operation and we fix it here.

BugLink: https://bugs.launchpad.net/bugs/1878232 commit c23ac90f upstream. c8sectpfe driver relied on CONFIG_FW_LOADER_USER_HELPER_FALLBACK option for loading its xp70 firmware. A previous commit removed this Kconfig option, as it is apparently harmful, but did not update the driver code which relied on it. This patch reworks the firmware loading into the start_feed callback. At this point we can be sure the rootfs is present, thereby removing the depedency on CONFIG_FW_LOADER_USER_HELPER_FALLBACK.

BugLink: https://bugs.launchpad.net/bugs/1878232 commit 715780ae upstream. The kerneldoc for request_firmware_nowait() says that it may call the provided cont() callback with @fw == NULL, if the firmware request fails. However, this is not the case when called with an empty string (""). This case is short-circuited by the 'name[0] == '\0'' check introduced in commit 471b095d ("firmware_class: make sure fw requests contain a name"), so _request_firmware() never gets to set the fw to NULL.

Alexey Kardashevskiy authored
BugLink: https://bugs.launchpad.net/bugs/1878232 commit dead1c84 upstream. The pseries platform uses the PCI_PROBE_DEVTREE method of PCI probing which reads "assigned-addresses" of every PCI device and initializes the device resources. However if the property is missing or zero sized, then there is no fallback of any kind and the PCI resources remain undiscovered, i.e. pdev->resource[] array remains empty. This adds a fallback which parses the "reg" property in pretty much same way except it marks resources as "unset" which later make Linux assign those resources proper addresses. This has an effect when: 1. a hypervisor failed to assign any resource for a device; 2. /chosen/linux,pci-probe-only=0 is in the DT so the system may try assigning a resource. Neither is likely to happen under PowerVM. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1878232 commit a0ca153f upstream. This patch fixes an issue I found in which we were dropping frames if we had enabled checksums on GRE headers that were encapsulated by either FOU or GUE. Without this patch I was barely able to get 1 Gb/s of throughput. With this patch applied I am now at least getting around 6 Gb/s. The issue is due to the fact that with FOU or GUE applied we do not provide a transport offset pointing to the GRE header, nor do we offload it in software as the GRE header is completely skipped by GSO and treated like a VXLAN or GENEVE type header. As such we need to prevent the stack from generating it and also prevent GRE from generating it via any interface we create.

BugLink: https://bugs.launchpad.net/bugs/1878232 commit ca620723 upstream. iomem_is_exclusive() requires a CPU physical address, but on some arches we supplied a PCI bus address instead. On most arches, pci_resource_to_user(res) returns "res->start", which is a CPU physical address. But on microblaze, mips, powerpc, and sparc, it returns the PCI bus address corresponding to "res->start". The result is that pci_mmap_resource() may fail when it shouldn't (if the bus address happens to match an existing resource), or it may succeed when it should fail (if the resource is exclusive but the bus address doesn't match it). Call iomem_is_exclusive() with "res->start", which is always a CPU physical address, not the result of pci_resource_to_user().

BugLink: https://bugs.launchpad.net/bugs/1878232 commit 5091730d upstream. The descriptor queues for sending (SDQs) and receiving (RDQs) packets are managed by two counters - producer and consumer - which are both 16-bit in size. A queue is considered full when the difference between the two equals the queue's maximum number of descriptors. However, if the producer counter overflows, then it's possible for the full queue check to fail, as it doesn't take the overflow into account. In such a case, descriptors already passed to the device - but for which a completion has yet to be posted - will be overwritten, thereby causing undefined behavior. The above can be achieved under heavy load (~30 netperf instances). Fix that by casting the subtraction result to u16, preventing it from being treated as a signed integer.

BugLink: https://bugs.launchpad.net/bugs/1878232 commit 4f0c40d9 upstream. Dccp verifies packet integrity, including length, at initial rcv in dccp_invalid_packet, later pulls headers in dccp_enqueue_skb. A call to sk_filter in-between can cause __skb_pull to wrap skb->len. skb_copy_datagram_msg interprets this as a negative value, so (correctly) fails with EFAULT. The negative length is reported in ioctl SIOCINQ or possibly in a DCCP_WARN in dccp_close. Introduce an sk_receive_skb variant that caps how small a filter program can trim packets, and call this in dccp with the header length. Excessively trimmed packets are now processed normally and queued for reception as 0B payloads. Fixes: 7c657876 ("[DCCP]: Initial implementation") Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1878232 commit 1ba5bf99 upstream. If we hit any of the error conditions inside xfrm_dump_sa(), then xfrm_state_walk_init() never gets called. However, we still call xfrm_state_walk_done() from xfrm_dump_sa_done(), which will crash because the state walk was never initialized properly. We can fix this by setting cb->args[0] only after we've processed the first element and checking this before calling xfrm_state_walk_done().
