commit 7c973012 upstream. After building the kernel with Clang, the following section mismatch warning appears: WARNING: vmlinux.o(.text+0x3bf19a6): Section mismatch in reference from the function ssc_probe() to the function .init.text:atmel_ssc_get_driver_data() The function ssc_probe() references the function __init atmel_ssc_get_driver_data(). This is often because ssc_probe lacks a __init annotation or the annotation of atmel_ssc_get_driver_data is wrong. Remove __init from atmel_ssc_get_driver_data to get rid of the mismatch.

commit deefd242 upstream. Raydium USB touchscreen fails to set config if LPM is enabled: [ 2.030658] usb 1-8: New USB device found, idVendor=2386, idProduct=3119 [ 2.030659] usb 1-8: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 2.030660] usb 1-8: Product: Raydium Touch System [ 2.030661] usb 1-8: Manufacturer: Raydium Corporation [ 7.132209] usb 1-8: can't set config #1, error -110 Same behavior can be observed on 2386:3114. Raydium claims the touchscreen supports LPM under Windows, so I used Microsoft USB Test Tools (MUTT) [1] to check its LPM status. MUTT shows that the LPM doesn't work under Windows, either.

commit 43279819 upstream. I was trying to solve a double free but I introduced a more serious NULL dereference bug. The problem is that if there is an IRQ which triggers immediately, then we need "info->uio_dev" but it's not set yet. This patch puts the original initialization back to how it was and just sets info->uio_dev to NULL on the error path so it should solve both the Oops and the double free.

commit 92539d3e upstream. Patch ad608fbc changed how events were subscribed to address an issue elsewhere. As a side effect of that change, the "add" callback was called before the event subscription was added to the list of subscribed events, causing the first event queued by the add callback (and possibly other events arriving soon afterwards) to be lost. Fix this by adding the subscription to the list before calling the "add" callback, and clean up afterwards if that fails.

commit a0e6e083 upstream modify_ldt(2) leaves the old LDT mapped after switching over to the new one. The old LDT gets freed and the pages can be re-used. Leaving the mapping in place can have security implications. The mapping is present in the userspace page tables and Meltdown-like attacks can read these freed and possibly reused pages. It's relatively simple to fix: unmap the old LDT and flush TLB before freeing the old LDT memory. This further allows to avoid flushing the TLB in map_ldt_struct() as the slot is unmapped and flushed by unmap_ldt_struct() or has never been mapped at all.

commit d52888aa upstream On 5-level paging the LDT remap area is placed in the middle of the KASLR randomization region and it can overlap with the direct mapping, the vmalloc or the vmap area. The LDT mapping is per mm, so it cannot be moved into the P4D page table next to the CPU_ENTRY_AREA without complicating PGD table allocation for 5-level paging. The 4 PGD slot gap just before the direct mapping is reserved for hypervisors, so it cannot be used. Move the direct mapping one slot deeper and use the resulting gap for the LDT remap area. The resulting layout is the same for 4 and 5 level paging. [ tglx: Massaged changelog ] Fixes: f55f0501 ("x86/pti: Put the LDT in its own PGD if PTI is on") Signed-off-by:

[ Upstream commit 8ef14c2c ] This reverts commit 6147b1cf. The reverted patch results in attempted write access to the source repository, even if that repository is mounted read-only. Output from "strace git status -uno --porcelain": getcwd("/tmp/linux-test", 129) = 16 open("/tmp/linux-test/.git/index.lock", O_RDWR|O_CREAT|O_EXCL|O_CLOEXEC, 0666) = -1 EROFS (Read-only file system) While git appears to be able to handle this situation, a monitored build environment (such as the one used for Chrome OS kernel builds) may detect it and bail out with an access violation error. On top of that, the attempted write access suggests that git _will_ write to the file even if a build output directory is specified. Users may have the reasonable expectation that the source repository remains untouched in that situation.

[ 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 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.

[ 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:

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 0bb2ae1b ] The function perf_init_event() creates a new event and assignes it to a PMU. This a done in a loop over all existing PMUs. For each listed PMU the event init function is called and if this function does return any other error than -ENOENT, the loop is terminated the creation of the event fails. If the event is invalid, return -ENOENT to try other PMUs. Signed-off-by:
