BugLink: https://bugs.launchpad.net/bugs/1878232 commit e895cdce upstream. In commit f02db315 ("ipv4: IP_TOS and IP_TTL can be specified as ancillary data") Francesco added IP_TOS values specified as integer. However, kernel sends to userspace (at recvmsg() time) an IP_TOS value in a single byte, when IP_RECVTOS is set on the socket. It can be very useful to reflect all ancillary options as given by the kernel in a subsequent sendmsg(), instead of aborting the sendmsg() with EINVAL after Francesco patch. So this patch extends IP_TOS ancillary to accept an u8, so that an UDP server can simply reuse same ancillary block without having to mangle it. Jesper can then augment https://github.com/netoptimizer/network-testing/blob/master/src/udp_example02.c to add TOS reflection ;) Fixes: f02db315 ("ipv4: IP_TOS and IP_TTL can be specified as ancillary data") Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1878232 commit fa17806c upstream. inet_forward_change() runs with RTNL held. We are allowed to sleep if required. If we use __in_dev_get_rtnl() instead of __in_dev_get_rcu(), we no longer have to use GFP_ATOMIC allocations in inet_netconf_notify_devconf(), meaning we are less likely to miss notifications under memory pressure, and wont touch precious memory reserves either and risk dropping incoming packets. inet_netconf_get_devconf() can also use GFP_KERNEL allocation.

BugLink: https://bugs.launchpad.net/bugs/1878232 commit 918c023f upstream. This patch corrects the logic for the IPv4 parsing so that it is consistent with how we handle IPv6. Specifically if we do not have the flow key indicating we want the addresses we still may need to take a look at the IP fragmentation bits and to see if we should stop after we have recognized the L3 header.

BugLink: https://bugs.launchpad.net/bugs/1878232 commit a69bf3c5 upstream. The adapter->pcicfg resource is either mapped via pci_iomap() or derived from adapter->db. During be_remove() this resource was ignored and so could remain mapped after remove. Add a flag to track whether adapter->pcicfg was mapped or not, then use that flag in be_unmap_pci_bars() to unmap if required.

BugLink: https://bugs.launchpad.net/bugs/1878232 commit e2127ae7 upstream. Tegra124 was accidentally left out when the number of TLB lines was parameterized in commit 11cec15b ("iommu/tegra-smmu: Parameterize number of TLB lines"). Fortunately this doesn't cause any noticeable regressions upstream, presumably because there aren't any use-cases that exercise enough pressure on the SMMU. But it is a regression nonetheless, so let's fix it. Fixes: 11cec15b ("iommu/tegra-smmu: Parameterize number of TLB lines") Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1878232 [ Upstream commit 3554e54a ] The driver is designed to drop Rx packets and reclaim the buffers when an allocation fails, and the network interface needs to safely handle this packet loss. Therefore, an allocation failure of Rx SKBs is relatively benign. However, the output of the warning message occurs with a high scheduling priority that can cause excessive jitter/latency for other high priority processing. This commit suppresses the warning messages to prevent scheduling problems while retaining the failure count in the statistics of the network interface. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1878232 [ Upstream commit 7717cbec ] i2400mu_bus_bm_wait_for_ack() invokes usb_get_urb(), which increases the refcount of the "notif_urb". When i2400mu_bus_bm_wait_for_ack() returns, local variable "notif_urb" becomes invalid, so the refcount should be decreased to keep refcount balanced. The issue happens in all paths of i2400mu_bus_bm_wait_for_ack(), which forget to decrease the refcnt increased by usb_get_urb(), causing a refcnt leak. Fix this issue by calling usb_put_urb() before the i2400mu_bus_bm_wait_for_ack() returns. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1878232 [ Upstream commit b87080ea ] After successfully running the IPC msgque test once, subsequent runs result in a test failure: $ sudo ./run_kselftest.sh TAP version 13 1..1 # selftests: ipc: msgque # Failed to get stats for IPC queue with id 0 # Failed to dump queue: -22 # Bail out! # # Pass 0 Fail 0 Xfail 0 Xpass 0 Skip 0 Error 0 not ok 1 selftests: ipc: msgque # exit=1 The dump_queue() function loops through the possible message queue index values using calls to msgctl(kern_id, MSG_STAT, ...) where kern_id represents the index value. The first time the test is ran, the initial index value of 0 is valid and the test is able to complete. The index value of 0 is not valid in subsequent test runs and the loop attempts to try index values of 1, 2, 3, and so on until a valid index value is found that corresponds to the message queue created earlier in the test. The msgctl() syscall returns -1 and sets errno to EINVAL when invalid index values are used. The test failure is caused by incorrectly comparing errno to -EINVAL when cycling through possible index values. Fix invalid test failures on subsequent runs of the msgque test by correctly comparing errno values to a non-negated EINVAL.

BugLink: https://bugs.launchpad.net/bugs/1878232 commit deccd16f upstream. Commit 5ea94e76 ("phy: add phy_mac_interrupt()") to use with PHY_IGNORE_INTERRUPT added a cancel_work_sync() into phy_mac_interrupt() which is allowed to sleep, whereas phy_mac_interrupt() is expected to be callable from interrupt context. Now that we have fixed how the PHY state machine treats PHY_IGNORE_INTERRUPT with respect to state changes, we can just set the new link state, and queue the PHY state machine for execution so it is going to read the new link state. For that to work properly, we need to update phy_change() not to try to invoke any interrupt callbacks if we have configured the PHY device for PHY_IGNORE_INTERRUPT, because that PHY device and its driver are not required to implement those.

BugLink: https://bugs.launchpad.net/bugs/1878232 commit d5c3d846 upstream. Commit 2c7b4921 ("phy: fix the use of PHY_IGNORE_INTERRUPT") changed a hunk in phy_state_machine() in the PHY_RUNNING case which was not needed. The change essentially makes the PHY library treat PHY devices with PHY_IGNORE_INTERRUPT to keep polling for the PHY device, even though the intent is not to do it. Fix this by reverting that specific hunk, which makes the PHY state machine wait for state changes, and stay in the PHY_RUNNING state for as long as needed.
