2020-01-21sparc32, leon: Stop adding vendor and device id to prom ambapp path componentsAndreas Larsson
These extra fields before the @ are not handled in of_node_name_eq, making commit b3e46d1a0590500335f0b95e669ad6d84b12b03a break node name comparisons for ambapp path components, thereby making LEON systems unable to boot. As there is no need for the tacked on vendor and device ID fields in the path component, resolve this situation by removing them.

2020-01-21net-sysfs: Fix reference count leakJouni Hogander
Netdev_register_kobject is calling device_initialize. In case of error reference taken by device_initialize is not given up. Drivers are supposed to call free_netdev in case of error. In non-error case the last reference is given up there and device release sequence is triggered. In error case this reference is kept and the release sequence is never started. Fix this by setting reg_state as NETREG_UNREGISTERED if registering fails. This is the rootcause for couple of memory leaks reported by Syzkaller: BUG: memory leak unreferenced object 0xffff8880675ca008 (size 256): comm "netdev_register", pid 281, jiffies 4294696663 (age 6.808s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [<0000000058ca4711>] kmem_cache_alloc_trace+0x167/0x280 [<000000002340019b>] device_add+0x882/0x1750 [<000000001d588c3a>] netdev_register_kobject+0x128/0x380 [<0000000011ef5535>] register_netdevice+0xa1b/0xf00 [<000000007fcf1c99>] __tun_chr_ioctl+0x20d5/0x3dd0 [<000000006a5b7b2b>] tun_chr_ioctl+0x2f/0x40 [<00000000f30f834a>] do_vfs_ioctl+0x1c7/0x1510 [<00000000fba062ea>] ksys_ioctl+0x99/0xb0 [<00000000b1c1b8d2>] __x64_sys_ioctl+0x78/0xb0 [<00000000984cabb9>] do_syscall_64+0x16f/0x580 [<000000000bde033d>] entry_SYSCALL_64_after_hwframe+0x44/0xa9 [<00000000e6ca2d9f>] 0xffffffffffffffff BUG: memory leak unreferenced object 0xffff8880668ba588 (size 8): comm "kobject_set_nam", pid 286, jiffies 4294725297 (age 9.871s) hex dump (first 8 bytes): 6e 72 30 00 cc be df 2b nr0....+ backtrace: [<00000000a322332a>] __kmalloc_track_caller+0x16e/0x290 [<00000000236fd26b>] kstrdup+0x3e/0x70 [<00000000dd4a2815>] kstrdup_const+0x3e/0x50 [<0000000049a377fc>] kvasprintf_const+0x10e/0x160 [<00000000627fc711>] kobject_set_name_vargs+0x5b/0x140 [<0000000019eeab06>] dev_set_name+0xc0/0xf0 [<0000000069cb12bc>] netdev_register_kobject+0xc8/0x320 [<00000000f2e83732>] register_netdevice+0xa1b/0xf00 [<000000009e1f57cc>] __tun_chr_ioctl+0x20d5/0x3dd0 [<000000009c560784>] tun_chr_ioctl+0x2f/0x40 [<000000000d759e02>] do_vfs_ioctl+0x1c7/0x1510 [<00000000351d7c31>] ksys_ioctl+0x99/0xb0 [<000000008390040a>] __x64_sys_ioctl+0x78/0xb0 [<0000000052d196b7>] do_syscall_64+0x16f/0x580 [<0000000019af9236>] entry_SYSCALL_64_after_hwframe+0x44/0xa9 [<00000000bc384531>] 0xffffffffffffffff v3 -> v4: Set reg_state to NETREG_UNREGISTERED if registering fails v2 -> v3: * Replaced BUG_ON with WARN_ON in free_netdev and netdev_release v1 -> v2: * Relying on driver calling free_netdev rather than calling put_device directly in error path Reported-by: syzbot+ad8ca40ecd77896d51e2@syzkaller.appspotmail.com Cc: David Miller <davem@davemloft.net> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Lukas Bulwahn <lukas.bulwahn@gmail.com> Signed-off-by: Jouni Hogander <jouni.hogander@unikie.com> Signed-off-by: David S.

https://git.kernel.org/pub/scm/linux/kernel/git/leon/linux-rdma Leon Romanovsky says: ==================== Use ODP MRs for kernel ULPs The following series extends MR creation routines to allow creation of user MRs through kernel ULPs as a proxy. The immediate use case is to allow RDS to work over FS-DAX, which requires ODP (on-demand-paging) MRs to be created and such MRs were not possible to create prior this series. The first part of this patchset extends RDMA to have special verb ib_reg_user_mr(). The common use case that uses this function is a userspace application that allocates memory for HCA access but the responsibility to register the memory at the HCA is on an kernel ULP. This ULP acts as an agent for the userspace application. The second part provides advise MR functionality for ULPs. This is integral part of ODP flows and used to trigger pagefaults in advance to prepare memory before running working set. The third part is actual user of those in-kernel APIs. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2020-01-21ipv6: sr: remove SKB_GSO_IPXIP6 on End.D* actionsYuki Taguchi
After LRO/GRO is applied, SRv6 encapsulated packets have SKB_GSO_IPXIP6 feature flag, and this flag must be removed right after decapulation procedure. Currently, SKB_GSO_IPXIP6 flag is not removed on End.D* actions, which creates inconsistent packet state, that is, a normal TCP/IP packets have the SKB_GSO_IPXIP6 flag. This behavior can cause unexpected fallback to GSO on routing to netdevices that do not support SKB_GSO_IPXIP6. For example, on inter-VRF forwarding, decapsulated packets separated into small packets by GSO because VRF devices do not support TSO for packets with SKB_GSO_IPXIP6 flag, and this degrades forwarding performance. This patch removes encapsulation related GSO flags from the skb right after the End.D* action is applied.

2020-01-21dmaengine: sun4i: Add support for cyclic requests with dedicated DMAStefan Mavrodiev
Currently the cyclic transfers can be used only with normal DMAs. They can be used by pcm_dmaengine module, which is required for implementing sound with sun4i-hdmi encoder. This is so because the controller can accept audio only from a dedicated DMA. This patch enables them, following the existing style for the scatter/gather type transfers.

2020-01-21drm/i915: Align engine->uabi_class/instance with i915_drm.hTvrtko Ursulin
In our ABI we have defined I915_ENGINE_CLASS_INVALID_NONE and I915_ENGINE_CLASS_INVALID_VIRTUAL as negative values which creates implicit coupling with type widths used in, also ABI, struct i915_engine_class_instance. One place where we export engine->uabi_class I915_ENGINE_CLASS_INVALID_VIRTUAL is from our our tracepoints. Because the type of the former is u8 in contrast to u16 defined in the ABI, 254 will be returned instead of 65534 which userspace would legitimately expect. Another place is I915_CONTEXT_PARAM_ENGINES. Therefore we need to align the type used to store engine ABI class and instance. v2: * Update the commit message mentioning get_engines and cc stable.
