[ Upstream commit bbcde0a7 ] Since commit b41d920a ("kbuild: deb-pkg: split generating packaging and build"), the build version of the kernel contained in a deb package is too low by 1. Prior to the bad commit, the kernel was built first, then the number in .version file was read out, and written into the debian control file. Now, the debian control file is created before the kernel is actually compiled, which is causing the version number mismatch. Let the mkdebian script pass KBUILD_BUILD_VERSION=${revision} to require the build system to use the specified version number.

[ Upstream commit bfaa9f85 ] Fixed a condition mistake due to which macvlans unicast item number 32 was not added in the unicast filter. The consequence is that when exactly 32 macvlans are created on NIC, the last created macvlan receives no traffic because its MAC was not registered in HW.

[ Upstream commit 7a1bb494 ] IOMMU fault may occurr on unbind/bind or if_down/if_up sequence. Although driver disables the rings on down, this is not enough. Due to internal HW design, during subsequent initialization NIC sometimes may reuse RX descriptors cache and write to the host memory from the descriptor cache. That's get catched by IOMMU on host. This patch invalidates the descriptor cache in NIC on interface down to prevent writing to the cached descriptors and to the memory pointed in those descriptors. Signed-off-by:

[ Upstream commit ba766b8b ] Since commit bacd75cf ("i40e/i40evf: Add capability exchange for outer checksum", 2017-04-06) the i40e driver has not reported support for IP-in-IP offloads. This likely occurred due to a bad rebase, as the commit extracts hw_enc_features into its own variable. As part of this change, it dropped the NETIF_F_FSO_IPXIP flags from the netdev->hw_enc_features. This was unfortunately not caught during code review. Fix this by adding back the missing feature flags. For reference, NETIF_F_GSO_IPXIP4 was added in commit 7e13318d ("net: define gso types for IPx over IPv4 and IPv6", 2016-05-20), replacing NETIF_F_GSO_IPIP and NETIF_F_GSO_SIT. NETIF_F_GSO_IPXIP6 was added in commit bf2d1df3 ("intel: Add support for IPv6 IP-in-IP offload", 2016-05-20). Signed-off-by:

[ Upstream commit d944b469 ] Currently if the driver does a TSO offload the bytecount sent to netdev_tx_sent_queue will be incorrect. This is because in ice_tso we overwrite the initial value that we set in ice_tx_map. This creates a mismatch between the Tx and Tx clean flow. In the Tx clean flow we calculate the bytecount (called total_bytes) as we clean the descriptors so the value used in the Tx clean path is correct. Fix this by using += in ice_tso instead of =. This fixes the mismatch in bytecount mentioned above. Signed-off-by:

[ Upstream commit 6ac22262 ] Currently jvmti agent can not be used because function scnprintf is not present in the agent libperf-jvmti.so. As a result the JVM when using such agent to record JITed code profiling information will fail on looking up scnprintf: java: symbol lookup error: lib/libperf-jvmti.so: undefined symbol: scnprintf This commit fixes that by reverting to the use of snprintf, that can be looked up, instead of scnprintf, adding a proper check for the returned value in order to print a better error message when the jitdump file pathname is too long. Checking the returned value also helps to comply with some recent gcc versions, like gcc8, which will fail due to truncated writing checks related to the -Werror=format-truncation= flag.

This didn't get detected in tip/sched/core because we were missing: commit cb538267 ("jump_label/lockdep: Assert we hold the hotplug lock for _cpuslocked() operations") Calls to build_sched_domains() post sched_init_smp() will hold the hotplug lock, it just so happens that this very first call is a special case. As stated by a comment in sched_init_smp(), "There's no userspace yet to cause hotplug operations" so this is a harmless warning. However, to both respect the semantics of underlying callees and make lockdep happy, take the hotplug lock in sched_init_smp(). This also satisfies the comment atop sched_init_domains() that says "Callers must hold the hotplug lock". Reported-by:

[ Upstream commit 6778be4e ] of_dma_configure() was *supposed* to be following the same logic as acpi_dma_configure() and only setting bus_dma_mask if some range was specified by the firmware. However, it seems that subtlety got lost in the process of fitting it into the differently-shaped control flow, and as a result the force_dma==true case ends up always setting the bus mask to the 32-bit default, which is not what anyone wants. Make sure we only touch it if the DT actually said so. Fixes: 6c2fb2ea ("of/device: Set bus DMA mask as appropriate") Reported-by:

[ Upstream commit 63237f87 ] [why] Removing connector reusage from DM to match the rest of the tree ended up revealing an issue that was surprisingly subtle. The original amdgpu code for DC that was submitted appears to have left a chunk in dm_dp_create_fake_mst_encoder() that tries to find a "master encoder", the likes of which isn't actually used or stored anywhere. It does so at the wrong time as well by trying to access parts of the drm_connector from the encoder init before it's actually been initialized. This results in a NULL pointer deref on MST hotplugs: [ 160.696613] BUG: unable to handle kernel NULL pointer dereference at 0000000000000000 [ 160.697234] PGD 0 P4D 0 [ 160.697814] Oops: 0010 [#1] SMP PTI [ 160.698430] CPU: 2 PID: 64 Comm: kworker/2:1 Kdump: loaded Tainted: G O 4.19.0Lyude-Test+ #2 [ 160.699020] Hardware name: HP HP ZBook 15 G4/8275, BIOS P70 Ver. 01.22 05/17/2018 [ 160.699672] Workqueue: events_long drm_dp_mst_link_probe_work [drm_kms_helper] [ 160.700322] RIP: 0010: (null) [ 160.700920] Code: Bad RIP value.

[ Upstream commit 6ca469e2 ] This reverts commit 0586feba This patch makes it to need get_vblank_counter callback in crtc to get frame counter from decon driver. However, drm_dev->max_vblank_count is a member unique to vendor's DRM driver but in case of ARM DRM, some CRTC devices don't provide the frame counter value. As a result, this patch made extension and clone mode not working. Instead of this patch, we may need separated max_vblank_count which belongs to each CRTC device, or need to implement frame counter emulation for them who don't support HW frame counter.

[ Upstream commit 1af6ab3b ] A quoted label reference doesn't expand to the node path and is taken as a literal string. Dropping the quotes can fix this unless the baudrate string is appended in which case we have to use the alias. At least on VF610, the problem was masked by setting the console in bootargs. Use the alias syntax with baudrate parameter so we can drop setting the console in bootargs.

[ Upstream commit e3e61f01 ] If gcc decides not to inline make_sensor_label(): WARNING: vmlinux.o(.text+0x4df549c): Section mismatch in reference from the function .create_device_attrs() to the function .init.text:.make_sensor_label() The function .create_device_attrs() references the function __init .make_sensor_label(). This is often because .create_device_attrs lacks a __init annotation or the annotation of .make_sensor_label is wrong. As .probe() can be called after freeing of __init memory, all __init annotiations in the driver are bogus, and should be removed. Signed-off-by:

[ Upstream commit 30356d08 ] qeth only registers its netdevice when the qeth device is first set online. Thus a device that has never been set online will trigger a WARN ("network todo 'hsi%d' but state 0") in unregister_netdev() when removed. Fix this by protecting the unregister step, just like we already protect against repeated registering of the netdevice. Fixes: d3d1b205 ("s390/qeth: allocate netdevice early") Reported-by:

[ Upstream commit bd74a7f9 ] Sniffing mode for L3 HiperSockets requires that no IP addresses are registered with the HW. The preferred way to achieve this is for userspace to delete all the IPs on the interface. But qeth is expected to also tolerate a configuration where that is not the case, by skipping the IP registration when in sniffer mode. Since commit 5f78e29c ("qeth: optimize IP handling in rx_mode callback") reworked the IP registration logic in the L3 subdriver, this no longer works. When the qeth device is set online, qeth_l3_recover_ip() now unconditionally registers all unicast addresses from our internal IP table. While we could fix this particular problem by skipping qeth_l3_recover_ip() on a sniffer device, the more future-proof change is to skip the IP address registration at the lowest level. This way we a) catch any future code path that attempts to register an IP address without considering the sniffer scenario, and b) continue to build up our internal IP table, so that if sniffer mode is switched off later we can operate just like normal.
