2017-04-12usb: xhci: add quirk flag for broken PED bitsFelipe Balbi
[ Upstream commit 41135de1e7fd14c6fcb9158404ba5c8fb97bf259 ] Some devices from Texas Instruments [1] suffer from a silicon bug where Port Enabled/Disabled bit should not be used to silence an erroneous device. The bug is so that if port is disabled with PED bit, an IRQ for device removal (or attachment) will never fire. Just for the sake of completeness, the actual problem lies with SNPS USB IP and this affects all known versions up to 3.00a. A separate patch will be added to dwc3 to enabled this quirk flag if version is <= 3.00a.

2017-04-12drm/i915: actually drive the BDW reserved IDsPaulo Zanoni
[ Upstream commit 98b2f01c8dfc8922a2af1fe82a1c40cac4911634 ] Back in 2014, commit fb7023e0e248 ("drm/i915: BDW: Adding Reserved PCI IDs.") added the reserved PCI IDs in order to try to make sure we had working drivers in case we ever released products using these IDs (since we had instances of this type of problem in the past). The problem is that the patch only touched the macros used by early-quirks.c and by the user space components that rely on i915_pciids.h, it didn't touch the macros used by i915_pci.c. So we correctly handled the stolen memory for these theoretical IDs, but we didn't actually drive the devices from i915.ko. So this patch fixes the original commit by actually making i915.ko drive these IDs, which was the goal. There's no information on what would be the GT count on these IDs, so we just go with the safer intel_broadwell_info, at the risk of ignoring a possibly inexistent BSD2_RING. I did some checking, and it seems that these IDs are driven by intel-gpu-tools, xf86-video-intel and libdrm (since they contain old copies of i915_pciids.h), but they are not checked by mesa. The alternative to this patch would be to just assume we're actually never going to use these IDs, and then remove them from our ID lists and make sure our user space components sync the latest i915_pciids.h copy. I'm fine with either approaches, as long as we make sure that every component tries to drive the same list of PCI IDs. Fixes: fb7023e0e248 ("drm/i915: BDW: Adding Reserved PCI IDs.")

2017-04-12ACPI / sysfs: Provide quirk mechanism to prevent GPE floodingLv Zheng
[ Upstream commit 9c4aa1eecb48cfac18ed5e3aca9d9ae58fbafc11 ] Sometimes, the users may require a quirk to be provided from ACPI subsystem core to prevent a GPE from flooding. Normally, if a GPE cannot be dispatched, ACPICA core automatically prevents the GPE from firing. But there are cases the GPE is dispatched by _Lxx/_Exx provided via AML table, and OSPM is lacking of the knowledge to get _Lxx/_Exx correctly executed to handle the GPE, thus the GPE flooding may still occur. The existing quirk mechanism can be enabled/disabled using the following commands to prevent such kind of GPE flooding during runtime: # echo mask > /sys/firmware/acpi/interrupts/gpe00 # echo unmask > /sys/firmware/acpi/interrupts/gpe00 To avoid GPE flooding during boot, we need a boot stage mechanism. This patch provides such a boot stage quirk mechanism to stop this kind of GPE flooding. This patch doesn't fix any feature gap but since the new feature gaps could be found in the future endlessly, and can disappear if the feature gaps are filled, providing a boot parameter rather than a DMI table should suffice.

2017-04-12nvme: simplify stripe quirkKeith Busch
[ Upstream commit e6282aef7b89a11d26e731060c4409b7aac278bf ] Some OEMs believe they own the Identify Controller vendor specific region and will repurpose it with their own values. While not common, we can't rely on the PCI VID:DID to tell use how to decode the field we reserved for this as the stripe size so we need to do something else for the list of devices using this quirk. The field was supposed to allow flexibility on the device's back-end striping, but it turned out that never materialized; the chunk is always the same as MDTS in the products subscribing to this quirk, so this patch removes the stripe_size field and sets the chunk to the max hw transfer size for the devices using this quirk.

[ Upstream commit 5241b1938a4d33eee3d3b43f23067c8e5b96db45 ] The AMW0_GUID1 wmi is not only found on Acer family but also other machines like Lenovo, Fujitsu and Medion. In the past, acer-wmi handled those non-Acer machines by quirks list. But actually acer-wmi driver was loaded on any machine that had AMW0_GUID1. This behavior is strange because those machines should be supported by appropriate wmi drivers. e.g. fujitsu-laptop, ideapad-laptop. This patch adds the logic to check the machine that has AMW0_GUID1 should be in Acer/Packard Bell/Gateway white list. But, it still keeps the quirk list of those supported non-acer machines for backward compatibility.

[ Upstream commit 093d24a204425f71f4f106b7e62c8df4b456e1cc ] Currently we use one shared global acpi_pci_root_ops structure to keep controller-specific ops. We pass its pointer to acpi_pci_root_create() and associate it with a host bridge instance for good. Such a design implies serious drawback. Any potential manipulation on the single system-wide acpi_pci_root_ops leads to kernel crash. The structure content is not really changing even across multiple host bridges creation; thus it was not an issue so far. In preparation for adding ECAM quirks mechanism (where controller-specific PCI ops may be different for each host bridge) allocate new acpi_pci_root_ops and fill in with data for each bridge. Now it is safe to have different controller-specific info. As a consequence free acpi_pci_root_ops when host bridge is released. No functional changes in this patch.

2017-04-12svcauth_gss: Close connection when dropping an incoming messageChuck Lever
[ Upstream commit 4d712ef1db05c3aa5c3b690a50c37ebad584c53f ] S5.3.3.1 of RFC 2203 requires that an incoming GSS-wrapped message whose sequence number lies outside the current window is dropped. The rationale is: The reason for discarding requests silently is that the server is unable to determine if the duplicate or out of range request was due to a sequencing problem in the client, network, or the operating system, or due to some quirk in routing, or a replay attack by an intruder. Discarding the request allows the client to recover after timing out, if indeed the duplication was unintentional or well intended. However, clients may rely on the server dropping the connection to indicate that a retransmit is needed. Without a connection reset, a client can wait forever without retransmitting, and the workload just stops dead. I've reproduced this behavior by running xfstests generic/323 on an NFSv4.0 mount with proto=rdma and sec=krb5i. To address this issue, have the server close the connection when it silently discards an incoming message due to a GSS sequence number problem. There are a few other places where the server will never reply. Change those spots in a similar fashion. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J.

With the previous hid-input fix, there is now a full support of the Type Cover and we can remove all specific bits from hid-core and hid-microsoft. hid-multitouch will automatically set HID_QUIRK_NO_INIT_REPORTS so we can also remove it from the list of ushbid quirks.

[ Upstream commit d8ec7595a013237f82d965dcf981571aeb41855b ] The ARM specifies that the system counter "must be implemented in an always-on power domain," and so we try to use the counter as a source of timekeeping across suspend/resume. Unfortunately, some SoCs (e.g., Rockchip's RK3399) do not keep the counter ticking properly when switched from their high-power clock to the lower-power clock used in system suspend. Support this quirk by adding a new device tree property.

2017-04-12clk: lpc32xx: add a quirk for PWM and MS clock dividersVladimir Zapolskiy
[ Upstream commit f84d42a9cffc4ecd96f1ce3a038f841782142eb2 ] In common clock framework CLK_DIVIDER_ONE_BASED or'ed with CLK_DIVIDER_ALLOW_ZERO flags indicates that 1) a divider clock may be set to zero value, 2) divider's zero value is interpreted as a non-divided clock. On the LPC32xx platform clock dividers of PWM and memory card clocks comply with the first condition, but zero value means a gated clock, thus it may happen that the divider value is not updated when the clock is enabled and the clock remains gated. The change adds one-shot quirks, which check for zero value of divider on initialization and set it to a non-zero value, therefore in runtime a gate clock will work as expected.

2017-04-12random: use chacha20 for get_random_int/longJason A. Donenfeld
commit f5b98461cb8167ba362ad9f74c41d126b7becea7 upstream. Now that our crng uses chacha20, we can rely on its speedy characteristics for replacing MD5, while simultaneously achieving a higher security guarantee. Before the idea was to use these functions if you wanted random integers that aren't stupidly insecure but aren't necessarily secure either, a vague gray zone, that hopefully was "good enough" for its users. With chacha20, we can strengthen this claim, since either we're using an rdrand-like instruction, or we're using the same crng as /dev/urandom. And it's faster than what was before. We could have chosen to replace this with a SipHash-derived function, which might be slightly faster, but at the cost of having yet another RNG construction in the kernel. By moving to chacha20, we have a single RNG to analyze and verify, and we also already get good performance improvements on all platforms. Implementation-wise, rather than use a generic buffer for both get_random_int/long and memcpy based on the size needs, we use a specific buffer for 32-bit reads and for 64-bit reads. This way, we're guaranteed to always have aligned accesses on all platforms. While slightly more verbose in C, the assembly this generates is a lot simpler than otherwise. Finally, on 32-bit platforms where longs and ints are the same size, we simply alias get_random_int to get_random_long. Signed-off-by: Jason A.

2017-04-12MIPS: Flush wrong invalid FTLB entry for huge pageHuacai Chen
commit 0115f6cbf26663c86496bc56eeea293f85b77897 upstream. On VTLB+FTLB platforms (such as Loongson-3A R2), FTLB's pagesize is usually configured the same as PAGE_SIZE. In such a case, Huge page entry is not suitable to write in FTLB. Unfortunately, when a huge page is created, its page table entries haven't created immediately. Then the TLB refill handler will fetch an invalid page table entry which has no "HUGE" bit, and this entry may be written to FTLB. Since it is invalid, TLB load/store handler will then use tlbwi to write the valid entry at the same place. However, the valid entry is a huge page entry which isn't suitable for FTLB. Our solution is to modify build_huge_handler_tail. Flush the invalid old entry (whether it is in FTLB or VTLB, this is in order to reduce branches) and use tlbwr to write the valid new entry.
