2019-01-16net: bpfilter: change section name of bpfilter UMH blob.Taehee Yoo1-1/+1
The section of bpfilter UMH blob is the ".bpfilter_umh". but this is not an explicit section. so linking warning occurred at compile time for the powerpc. So, this patch makes use of the ".rodata" instead of the ".bpfilter_umh". Config condition: CONFIG_BPFILTER=y CONFIG_BPFILTER_UMH=y Result: ld: warning: orphan section `.bpfilter_umh' from `net/bpfilter/bpfilter_umh_blob.o' being placed in section `.bpfilter_umh' Fixes: 61fbf5933d42 ("net: bpfilter: restart bpfilter_umh when error occurred") Reported-by: Stephen Rothwell <[email protected]> Signed-off-by: Taehee Yoo <[email protected]> Signed-off-by: David S.

2019-01-16drm/amd/display: Detach backlight from streamDavid Francis4-15/+3
[Why] Backlight is conceptually a property of links, not streams. All backlight programming is done on links, but there is a stream property bl_pwm_level that is used to restore backlight on dpms on and s3 resume. This is unnecessary, as backlight is already restored by hardware with no driver intervention.

2019-01-16net_sched: refetch skb protocol for each filterCong Wang1-2/+1
Martin reported a set of filters don't work after changing from reclassify to continue. Looking into the code, it looks like skb protocol is not always fetched for each iteration of the filters. But, as demonstrated by Martin, TC actions could modify skb->protocol, for example act_vlan, this means we have to refetch skb protocol in each iteration, rather than using the one we fetch in the beginning of the loop. This bug is _not_ introduced by commit 3b3ae880266d ("net: sched: consolidate tc_classify{,_compat}"), technically, if act_vlan is the only action that modifies skb protocol, then it is commit c7e2b9689ef8 ("sched: introduce vlan action") which introduced this bug.

2019-01-16nvme-pci: fix nvme_setup_irqs()Ming Lei1-8/+13
When -ENOSPC is returned from pci_alloc_irq_vectors_affinity(), we still try to allocate multiple irq vectors again, so irq queues covers the admin queue actually. But we don't consider that, then number of the allocated irq vector may be same with sum of io_queues[HCTX_TYPE_DEFAULT] and io_queues[HCTX_TYPE_READ], this way is obviously wrong, and finally breaks nvme_pci_map_queues(), and warning from pci_irq_get_affinity() is triggered. IRQ queues should cover admin queues, this patch makes this point explicitely in nvme_calc_io_queues(). We got severl boot failure internal report on aarch64, so please consider to fix it in v4.20.

cancel_delayed_work_sync() was called for any queue, but it should only be called for the queue that is associated with the currently running job. Otherwise, if two filehandles are streaming at the same time, then closing the first will cancel the work which might still be running for a job from the second filehandle. As a result the second filehandle will never be able to finish the job and an attempt to stop streaming on that second filehandle will stall.

kaslr_early_init() is called with the kernel mapped at its link time offset, and if it returns with a non-zero offset, the kernel is unmapped and remapped again at the randomized offset. During its execution, kaslr_early_init() also randomizes the base of the module region and of the linear mapping of DRAM, and sets two variables accordingly. However, since these variables are assigned with the caches on, they may get lost during the cache maintenance that occurs when unmapping and remapping the kernel, so ensure that these values are cleaned to the PoC.

2019-01-16arm64: kpti: Update arm64_kernel_use_ng_mappings() when forced onJames Morse1-1/+4
Since commit b89d82ef01b3 ("arm64: kpti: Avoid rewriting early page tables when KASLR is enabled"), a kernel built with CONFIG_RANDOMIZE_BASE can decide early whether to use non-global mappings by checking the kaslr_offset(). A kernel built without CONFIG_RANDOMIZE_BASE, instead checks the cpufeature static-key. This leaves a gap where CONFIG_RANDOMIZE_BASE was enabled, no kaslr seed was provided, but kpti was forced on using the cmdline option. When the decision is made late, kpti_install_ng_mappings() will re-write the page tables, but arm64_kernel_use_ng_mappings()'s value does not change as it only tests the cpufeature static-key if CONFIG_RANDOMIZE_BASE is disabled. This function influences PROT_DEFAULT via PTE_MAYBE_NG, and causes pgattr_change_is_safe() to catch nG->G transitions when the unchanged PROT_DEFAULT is used as part of PAGE_KERNEL_RO: [ 1.942255] alternatives: patching kernel code [ 1.998288] ------------[ cut here ]------------ [ 2.000693] kernel BUG at arch/arm64/mm/mmu.c:165!

After commit 1c25324caf82 ("net/sched: act_tunnel_key: Don't dump dst port if it wasn't set"), act_tunnel_key doesn't dump anymore the destination port, unless it was explicitly configured. This caused systematic failures in the following TDC test case: 7a88 - Add tunnel_key action with cookie parameter Avoid matching zero values of TCA_TUNNEL_KEY_ENC_DST_PORT to let the test pass again.

After merge of commit 80ef0f22ceda ("net/sched: act_tunnel_key: Allow key-less tunnels"), act_tunnel_key does not reject anymore requests to install 'set' rules where the key id is missing. Therefore, drop the following TDC testcase: ba4e - Add tunnel_key set action with missing mandatory id parameter because it's going to become a systematic fail as soon as userspace iproute2 will start supporting key-less tunnels.
