2018-06-27proc: add proc_seq_releaseChunyu Hu
kmemleak reported some memory leak on reading proc files. After adding some debug lines, find that proc_seq_fops is using seq_release as release handler, which won't handle the free of 'private' field of seq_file, while in fact the open handler proc_seq_open could create the private data with __seq_open_private when state_size is greater than zero. So after reading files created with proc_create_seq_private, such as /proc/timer_list and /proc/vmallocinfo, the private mem of a seq_file is not freed. Fix it by adding the paired proc_seq_release as the default release handler of proc_seq_ops instead of seq_release.

2018-06-27ARM64: dts: meson-gxl: fix Mali GPU compatible stringMartin Blumenstingl
meson-gxl-mali.dtsi is only used on GXL SoCs. Thus it should use the GXL specific compatible string instead of the GXBB one. For now this is purely cosmetic since the (out-of-tree) lima driver for this GPU currently uses the "arm,mali-450" match instead of the SoC specific one. However, update the .dts to match the documentation since this driver behavior might change in the future.

Like the odroid-c2 and wetek, the s400 uses the RTL8211F and seems to suffer from the kind of stability issue. Doing an iperf3 download test, we can see a significant number of LPI interrupts on the tx path. After a short while (5 to 15 seconds), the network connection dies. If using rootfs over NFS, the connection may also break during the boot sequence. We still don't have a real explanation for this problem so let's disable EEE once again.

There is a problem with the sd-uhs mode when doing a soft reboot. Switching back from 1.8v to 3.3v messes with the card, which no longer respond (timeout errors). According to the specification, we should perform a card reset (power cycling the card) but this is something we cannot control on this design. Then the only solution to restore the communication with the card is an "unplug-plug" which is not acceptable Until we find a solution, if any, disable the sd-uhs modes on this design. For the people using uhs at the moment, there will a performance drop as a result.

Currently, amdgpu_do_flip() spinlocks crtc->dev->event_lock and releases it only after committing updates to the stream. dc_commit_updates_for_stream() should be moved out of spinlock for the below reasons: 1. event_lock is supposed to protect access to acrct->pflip_status _only_ 2. dc_commit_updates_for_stream() has potential sleep's and also its not appropriate to be in an atomic state for such long sequences of code.

The implementation of flush_icache_range() includes instruction sequences which are themselves patched at runtime, so it is not safe to call from the patching framework. This patch reworks the alternatives cache-flushing code so that it rolls its own internal D-cache maintenance using DC CIVAC before invalidating the entire I-cache after all alternatives have been applied at boot. Modules don't cause any issues, since flush_icache_range() is safe to call by the time they are loaded.

2018-06-27dm thin: handle running out of data space vs concurrent discardMike Snitzer
Discards issued to a DM thin device can complete to userspace (via fstrim) _before_ the metadata changes associated with the discards is reflected in the thinp superblock (e.g. free blocks). As such, if a user constructs a test that loops repeatedly over these steps, block allocation can fail due to discards not having completed yet: 1) fill thin device via filesystem file 2) remove file 3) fstrim From initial report, here: https://www.redhat.com/archives/dm-devel/2018-April/msg00022.html "The root cause of this issue is that dm-thin will first remove mapping and increase corresponding blocks' reference count to prevent them from being reused before DISCARD bios get processed by the underlying layers. However. increasing blocks' reference count could also increase the nr_allocated_this_transaction in struct sm_disk which makes smd->old_ll.nr_allocated + smd->nr_allocated_this_transaction bigger than smd->old_ll.nr_blocks. In this case, alloc_data_block() will never commit metadata to reset the begin pointer of struct sm_disk, because sm_disk_get_nr_free() always return an underflow value." While there is room for improvement to the space-map accounting that thinp is making use of: the reality is this test is inherently racey and will result in the previous iteration's fstrim's discard(s) completing vs concurrent block allocation, via dd, in the next iteration of the loop. No amount of space map accounting improvements will be able to allow user's to use a block before a discard of that block has completed. So the best we can really do is allow DM thinp to gracefully handle such aggressive use of all the pool's data by degrading the pool into out-of-data-space (OODS) mode. We _should_ get that behaviour already (if space map accounting didn't falsely cause alloc_data_block() to believe free space was available).. but short of that we handle the current reality that dm_pool_alloc_data_block() can return -ENOSPC.

2018-06-27selftests/bpf: Test sys_connect BPF hooks with TFOAndrey Ignatov
TCP Fast Open is triggered by sys_sendmsg with MSG_FASTOPEN flag for SOCK_STREAM socket. Even though it's sys_sendmsg, it eventually calls __inet_stream_connect the same way sys_connect does for TCP. __inet_stream_connect, in turn, already has BPF hooks for sys_connect. That means TFO is already covered by BPF_CGROUP_INET{4,6}_CONNECT and the only missing piece is selftest. The patch adds selftest for TFO.

2018-06-27x86/mm: Drop unneeded __always_inline for p4d page table helpersKirill A. Shutemov
This reverts the following commits: 1ea66554d3b0 ("x86/mm: Mark p4d_offset() __always_inline") 046c0dbec023 ("x86: Mark native_set_p4d() as __always_inline") p4d_offset(), native_set_p4d() and native_p4d_clear() were marked __always_inline in attempt to move __pgtable_l5_enabled into __initdata section. It was required as KASAN initialization code is a user of USE_EARLY_PGTABLE_L5, so all pgtable_l5_enabled() translated to __pgtable_l5_enabled there. This includes pgtable_l5_enabled() called from inline p4d helpers. If compiler would decided to not inline these p4d helpers, but leave them standalone, we end up with section mismatch. We don't need __always_inline here anymore. __pgtable_l5_enabled moved back to be __ro_after_init.

2018-06-27x86/entry/64/compat: Fix "x86/entry/64/compat: Preserve r8-r11 in int $0x80"Andy Lutomirski
Commit: 8bb2610bc496 ("x86/entry/64/compat: Preserve r8-r11 in int $0x80") was busted: my original patch had a minor conflict with some of the nospec changes, but "git apply" is very clever and silently accepted the patch by making the same changes to a different function in the same file. There was obviously a huge offset, but "git apply" for some reason doesn't feel any need to say so. Move the changes to the correct function. Now the test_syscall_vdso_32 selftests passes. If anyone cares to observe the original problem, try applying the patch at: https://lore.kernel.org/lkml/d4c4d9985fbe64f8c9e19291886453914b48caee.1523975710.git.luto@kernel.org/raw to the kernel at 316d097c4cd4e7f2ef50c40cff2db266593c4ec4: - "git am" and "git apply" accept the patch without any complaints at all - "patch -p1" at least prints out a message about the huge offset.
