2019-11-06lwtunnel: add options process for cmp_encapXin Long
When comparing two tun_info, dst_cache member should have been skipped, as dst_cache is a per cpu pointer and they are always different values even in two tun_info with the same keys. So this patch is to skip dst_cache member and compare the key, mode and options_len only. For the future opts setting support, also to compare options.

2019-11-06drm/amdgpu: add dummy read by engines for some GCVM status registers in gfx10changzhu
The GRBM register interface is now capable of bursting 1 cycle per register wr->wr, wr->rd much faster than previous muticycle per transaction done interface. This has caused a problem where status registers requiring HW to update have a 1 cycle delay, due to the register update having to go through GRBM. For cp ucode, it has realized dummy read in cp firmware.It covers the use of WAIT_REG_MEM operation 1 case only.So it needs to call gfx_v10_0_wait_reg_mem in gfx10. Besides it also needs to add warning to update firmware in case firmware is too old to have function to realize dummy read in cp firmware. For sdma ucode, it hasn't realized dummy read in sdma firmware. sdma is moved to gfxhub in gfx10. So it needs to add dummy read in driver between amdgpu_ring_emit_wreg and amdgpu_ring_emit_reg_wait for sdma_v5_0.

2019-11-06Merge branch 'net-tls-add-a-TX-lock'David S. Miller
Jakub Kicinski says: ==================== net/tls: add a TX lock Some time ago Pooja and Mallesham started reporting crashes with an async accelerator. After trying to poke the existing logic into shape I came to the conclusion that it can't be trusted, and to preserve our sanity we should just add a lock around the TX side. First patch removes the sk_write_pending checks from the write space callbacks. Those don't seem to have a logical justification. Patch 2 adds the TX lock and patch 3 associated test (which should hang with current net). Mallesham reports that even with these fixes applied the async accelerator workload still occasionally hangs waiting for socket memory. I suspect that's strictly related to the way async crypto is integrated in TLS, so I think we should get these into net or net-next and move from there. ==================== Signed-off-by: David S.

2019-11-06net/tls: add a TX lockJakub Kicinski
TLS TX needs to release and re-acquire the socket lock if send buffer fills up. TLS SW TX path currently depends on only allowing one thread to enter the function by the abuse of sk_write_pending. If another writer is already waiting for memory no new ones are allowed in. This has two problems: - writers don't wake other threads up when they leave the kernel; meaning that this scheme works for single extra thread (second application thread or delayed work) because memory becoming available will send a wake up request, but as Mallesham and Pooja report with larger number of threads it leads to threads being put to sleep indefinitely; - the delayed work does not get _scheduled_ but it may _run_ when other writers are present leading to crashes as writers don't expect state to change under their feet (same records get pushed and freed multiple times); it's hard to reliably bail from the work, however, because the mere presence of a writer does not guarantee that the writer will push pending records before exiting. Ensuring wakeups always happen will make the code basically open code a mutex. Just use a mutex. The TLS HW TX path does not have any locking (not even the sk_write_pending hack), yet it uses a per-socket sg_tx_data array to push records.

2019-11-06net/tls: don't pay attention to sk_write_pending when pushing partial recordsJakub Kicinski
sk_write_pending being not zero does not guarantee that partial record will be pushed. If the thread waiting for memory times out the pending record may get stuck. In case of tls_device there is no path where parial record is set and writer present in the first place. Partial record is set only in tls_push_sg() and tls_push_sg() will return an error immediately. All tls_device callers of tls_push_sg() will return (and not wait for memory) if it failed.

2019-11-06HID: wacom: generic: Treat serial number and related fields as unsignedJason Gerecke
The HID descriptors for most Wacom devices oddly declare the serial number and other related fields as signed integers. When these numbers are ingested by the HID subsystem, they are automatically sign-extended into 32-bit integers. We treat the fields as unsigned elsewhere in the kernel and userspace, however, so this sign-extension causes problems. In particular, the sign-extended tool ID sent to userspace as ABS_MISC does not properly match unsigned IDs used by xf86-input-wacom and libwacom. We introduce a function 'wacom_s32tou' that can undo the automatic sign extension performed by 'hid_snto32'. We call this function when processing the serial number and related fields to ensure that we are dealing with and reporting the unsigned form. We opt to use this method rather than adding a descriptor fixup in 'wacom_hid_usage_quirk' since it should be more robust in the face of future devices.

2019-11-06drm/amd/display: Add ENGINE_ID_DIGD condition check for Navi14Zhan Liu
[Why] Navi10 has 6 PHY, but Navi14 only has 5 PHY, that is because there is no ENGINE_ID_DIGD in Navi14. Without this patch, many HDMI related issues (e.g. HDMI S3 resume failure, HDMI pink screen on boot) will be observed. [How] If "eng_id" is larger than ENGINE_ID_DIGD, then add "eng_id" by 1.
