2021-02-18i40e: Fix flow for IPv6 next header (extension header)Slawomir Laba
When a packet contains an IPv6 header with next header which is an extension header and not a protocol one, the kernel function skb_transport_header called with such sk_buff will return a pointer to the extension header and not to the TCP one. The above explained call caused a problem with packet processing for skb with encapsulation for tunnel with I40E_TX_CTX_EXT_IP_IPV6. The extension header was not skipped at all. The ipv6_skip_exthdr function does check if next header of the IPV6 header is an extension header and doesn't modify the l4_proto pointer if it points to a protocol header value so its safe to omit the comparison of exthdr and l4.hdr pointers. The ipv6_skip_exthdr can return value -1. This means that the skipping process failed and there is something wrong with the packet so it will be dropped.

2021-02-18cpufreq: ACPI: Set cpuinfo.max_freq directly if max boost is knownRafael J. Wysocki
Commit 3c55e94c0ade ("cpufreq: ACPI: Extend frequency tables to cover boost frequencies") attempted to address a performance issue involving acpi-cpufreq, the schedutil governor and scale-invariance on x86 by extending the frequency tables created by acpi-cpufreq to cover the entire range of "turbo" (or "boost") frequencies, but that caused frequencies reported via /proc/cpuinfo and the scaling_cur_freq attribute in sysfs to change which may confuse users and monitoring tools. For this reason, revert the part of commit 3c55e94c0ade adding the extra entry to the frequency table and use the observation that in principle cpuinfo.max_freq need not be equal to the maximum frequency listed in the frequency table for the given policy. Namely, modify cpufreq_frequency_table_cpuinfo() to allow cpufreq drivers to set their own cpuinfo.max_freq above that frequency and change acpi-cpufreq to set cpuinfo.max_freq to the maximum boost frequency found via CPPC. This should be sufficient to let all of the cpufreq subsystem know the real maximum frequency of the CPU without changing frequency reporting.

2021-02-18cpufreq: qcom-hw: drop devm_xxx() calls from init/exit hooksShawn Guo
Commit f17b3e44320b ("cpufreq: qcom-hw: Use devm_platform_ioremap_resource() to simplify code") introduces a regression on platforms using the driver, by failing to initialise a policy, when one is created post hotplug. When all the CPUs of a policy are hoptplugged out, the call to .exit() and later to devm_iounmap() does not release the memory region that was requested during devm_platform_ioremap_resource(). Therefore, a subsequent call to .init() will result in the following error, which will prevent a new policy to be initialised: [ 3395.915416] CPU4: shutdown [ 3395.938185] psci: CPU4 killed (polled 0 ms) [ 3399.071424] CPU5: shutdown [ 3399.094316] psci: CPU5 killed (polled 0 ms) [ 3402.139358] CPU6: shutdown [ 3402.161705] psci: CPU6 killed (polled 0 ms) [ 3404.742939] CPU7: shutdown [ 3404.765592] psci: CPU7 killed (polled 0 ms) [ 3411.492274] Detected VIPT I-cache on CPU4 [ 3411.492337] GICv3: CPU4: found redistributor 400 region 0:0x0000000017ae0000 [ 3411.492448] CPU4: Booted secondary processor 0x0000000400 [0x516f802d] [ 3411.503654] qcom-cpufreq-hw 17d43000.cpufreq: can't request region for resource [mem 0x17d45800-0x17d46bff] With that being said, the original code was tricky and skipping memory region request intentionally to hide this issue. The true cause is that those devm_xxx() device managed functions shouldn't be used for cpufreq init/exit hooks, because &pdev->dev is alive across the hooks and will not trigger auto resource free-up. Let's drop the use of device managed functions and manually allocate/free resources, so that the issue can be fixed properly.

2021-02-18HID: wacom: Ignore attempts to overwrite the touch_max value from HIDJason Gerecke
The `wacom_feature_mapping` function is careful to only set the the touch_max value a single time, but this care does not extend to the `wacom_wac_finger_event` function. In particular, if a device sends multiple HID_DG_CONTACTMAX items in a single feature report, the driver will end up retaining the value of last item. The HID descriptor for the Cintiq Companion 2 does exactly this. It incorrectly sets a "Report Count" of 2, which will cause the driver to process two HID_DG_CONTACTCOUNT items. The first item has the actual count, while the second item should have been declared as a constant zero. The constant zero is the value the driver ends up using, however, since it is the last HID_DG_CONTACTCOUNT in the report. Report ID (16), Usage (Contact Count Maximum), ; Contact count maximum (55h, static value) Report Count (2), Logical Maximum (10), Feature (Variable), To address this, we add a check that the touch_max is not already set within the `wacom_wac_finger_event` function that processes the HID_DG_TOUCHMAX item. We emit a warning if the value is set and ignore the updated value. This could potentially cause problems if there is a tablet which has a similar issue but requires the last item to be used. This is unlikely, however, since it would have to have a different non-zero value for HID_DG_CONTACTMAX earlier in the same report, which makes no sense except in the case of a firmware bug. Note that cases where the HID_DG_CONTACTMAX items are in different reports is already handled (and similarly ignored) by `wacom_feature_mapping` as mentioned above.

2021-02-18opp: Don't skip freq update for different frequencyJonathan Marek
We skip the OPP update if the current and target OPPs are same. This is fine for the devices that don't support frequency but may cause issues for the ones that need to program frequency. An OPP entry doesn't really signify a single operating frequency but rather the highest frequency at which the other properties of the OPP entry apply. And we may reach here with different frequency values, while all of them would point to the same OPP entry in the OPP table. We just need to update the clock frequency in that case, though in order to not add special exit points we reuse the code flow from a normal path. While at it, rearrange the conditionals in the 'if' statement to check 'enabled' flag at the end.

Code clean-up. * Remove unnecessary \n termination from dev_*() messages. * Remove 'char *fmt' to define strings to stay within 80 column limit. Not needed since coding guidelines increased to 100 columns limit. Keeping format in place allows static code checkers to validate the arguments. * Tighten up vertical spacing.

When enabling output using PTP_CLK_REQ_PEROUT, need to align the output clock to the internal 1 PPS clock. Signed-off-by: Vincent Cheng <vincent.cheng.xh@renesas.com> Acked-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-02-17ptp: ptp_clockmatrix: Add wait_for_sys_apll_dpll_lock.Vincent Cheng
Part of the device initialization aligns the rising edge of the output clock to the internal 1 PPS clock. If the system APLL and DPLL is not locked, then the alignment will fail and there will be a fixed offset between the internal 1 PPS clock and the output clock. After loading the device firmware, poll the system APLL and DPLL for locked state prior to initialization, timing out after 2 seconds.

2021-02-17net: stmmac: dwmac-sun8i: Add a shutdown callbackSamuel Holland
The Ethernet MAC and PHY are usually major consumers of power on boards which may not be able to fully power off (those with no PMIC). Powering down the MAC and internal PHY saves power while these boards are "off". Reviewed-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Samuel Holland <samuel@sholland.org> Signed-off-by: David S.

Ocelot now uses include/linux/dsa/ocelot.h which makes use of CONFIG_PACKING to pack/unpack bits into the Injection/Extraction Frame Headers. So it needs to explicitly select it, otherwise there might be build errors due to the missing dependency.
