commit ebac62fe upstream. Both tunnel6_protocol and tunnel46_protocol share the same error handler, tunnel6_err(), which traverses through tunnel6_handlers list. For ipip6 tunnels, we need to traverse tunnel46_handlers as we do e.g. in tunnel46_rcv(). Current code can generate an ICMPv6 error message with an IPv4 packet embedded in it.

commit 777d738a upstream. create_request_message() computes the maximum length of a message, but uses the wrong type for the time stamp: sizeof(struct timespec) may be 8 or 16 depending on the architecture, while sizeof(struct ceph_timespec) is always 8, and that is what gets put into the message. Found while auditing the uses of timespec for y2038 problems. Fixes: b8e69066 ("ceph: include time stamp in every MDS request") Signed-off-by:

commit 7b3d770c upstream. ib_req_notify_cq(IB_CQ_REPORT_MISSED_EVENTS) returns a positive value if WCs were added to a CQ after the last completion upcall but before the CQ has been re-armed. Commit 7f23f6f6 ("xprtrmda: Reduce lock contention in completion handlers") assumed that when ib_req_notify_cq() returned a positive RC, the CQ had also been successfully re-armed, making it safe to return control to the provider without losing any completion signals. That is an invalid assumption. Change both completion handlers to continue polling while ib_req_notify_cq() returns a positive value. Fixes: 7f23f6f6 ("xprtrmda: Reduce lock contention in ...")

OF does report a MEM64 aperture, but before this patch, pci_determine_mem_io_space() ignored it. Add support for host bridge apertures with 64-bit PCI addresses. Also set IORESOURCE_MEM_64 for PCI device and bridge resources in PCI 64-bit memory space. Sparc doesn't actually print the device and bridge resources, but after this patch, we should have the equivalent of this: pci_sun4v f02dbcfc: PCI host bridge to bus 0000:00 pci_bus 0000:00: root bus resource [io 0x804000000000-0x80400fffffff] (bus address [0x0000-0xfffffff]) pci_bus 0000:00: root bus resource [mem 0x800000000000-0x80007effffff] (bus address [0x00000000-0x7effffff]) pci_bus 0000:00: root bus resource [mem 0x800100000000-0x8007ffffffff] (bus address [0x100000000-0x7ffffffff]) pci 0000:00:01.0: bridge window [mem 0x800100000000-0x8004afffffff 64bit pref] [bhelgaas: changelog, URL to David's report] Fixes: d63e2e1f ("sparc/PCI: Clip bridge windows to fit in upstream windows") Link: http://lkml.kernel.org/r/5514391F.2030300@oracle.comReported-by:

commit 76d63c2b upstream. The "compatible" property text contradicts even the example given in the MMCIF binding document itself; moreover, the Renesas MMCIF driver only matches on the generic "compatible" string and doesn't look for the SoC specific strings at all.

commit 75c08f17 upstream. Commit 68bab866 ("mfd: twl6040: Optional clk32k clock handling") added clock handling for the 32k clock from palmas-clk. However, that patch did not consider a typical situation where twl6040 is built-in, and palmas-clk is a loadable module like we have in omap2plus_defconfig. If palmas-clk is not loaded before twl6040 probes, we will get a "clk32k is not handled" warning during booting. This means that any drivers relying on this clock will mysteriously fail, including omap5-uevm WLAN and audio. Note that for WLAN, we probably should also eventually get the clk32kgaudio for MMC3 directly as that's shared between audio and WLAN SDIO at least for omap5-uevm. It seems the WLAN chip cannot get it as otherwise MMC3 won't get properly probed. Fixes: 68bab866 ("mfd: twl6040: Optional clk32k clock handling") Signed-off-by:

commit cc6a7aab upstream. The gss_key_timeout() function causes a harmless warning in some configurations, e.g. ARM imx_v6_v7_defconfig with gcc-5.2, if the compiler cannot figure out the state of the 'expire' variable across an rcu_read_unlock(): net/sunrpc/auth_gss/auth_gss.c: In function 'gss_key_timeout': net/sunrpc/auth_gss/auth_gss.c:1422:211: warning: 'expire' may be used uninitialized in this function [-Wmaybe-uninitialized] To avoid this warning without adding a bogus initialization, this rewrites the function so the comparison is done inside of the critical section. As a side-effect, it also becomes slightly easier to understand because the implementation now more closely resembles the comment above it. Signed-off-by:

commit 3c67d839 upstream. In its original version, drm_framebuffer_init() returned a negative int if drm_mode_object_get() failed (f453ba04, "DRM: add mode setting support"). This was accidentally disabled by commit 4b096ac1 ("drm: revamp locking around fb creation/destruction"). Thus, drm_framebuffer_init() pretends success if drm_mode_object_get() failed.

commit 54c09889 upstream. The z2 machine calls pxa27x_set_pwrmode() in order to power off the machine, but this function gets discarded early at boot because it is marked __init, as pointed out by kbuild: WARNING: vmlinux.o(.text+0x145c4): Section mismatch in reference from the function z2_power_off() to the function .init.text:pxa27x_set_pwrmode() The function z2_power_off() references the function __init pxa27x_set_pwrmode(). This is often because z2_power_off lacks a __init annotation or the annotation of pxa27x_set_pwrmode is wrong. This removes the __init section modifier to fix rebooting and the build error.

commit ce938001 upstream. The LDO1 driver is using the arizona_of_get_named_gpio helper function which will return 0 if an error was encountered whilst parsing the GPIO, as under the pdata scheme 0 was not being treated as a valid GPIO. However, since the regulator framework was expanded to allow the use of GPIO 0 this causes us to attempt to register GPIO 0 when we encountered an error parsing the device tree. This patch uses of_get_named_gpio directly and sets the ena_gpio_initialized flag based on the return value.

commit 58b0497d upstream. The requested bit rate can be outside the range supported by the driver. The maximum bit rate this driver supports at the moment is 400Khz. If the requested bit rate is larger than the maximum supported by the driver, set the bitrate to the maximum supported before bitrate_khz is calculated. Maximum speed supported by the driver can be increased to 1Mhz by adding support for "fast plus mode" in the future.

commit 987008db upstream. Currently, after determining the minimum value for the High period (TCKH) the remainder of the internal clock pulses is set as the Low period (TCKL). This causes the i2c clock duty cycle to be much less than 50%. Modify the starting position to TCKH and TCKL at 50% of the internal clock, and adjusts the TCKH and TCKL values from there should the minimum value for TCKL not be met. This results in duty cycles closer to 50%. Fixes: commit 27bce457 ("i2c: img-scb: Add Imagination Technologies I2C SCB driver") Signed-off-by:

commit 0e59378b upstream. The code to read from the master read fifo, and write to the master write fifo, checks a bit in an SCB register before every byte to ensure that the fifo is not full (write fifo) or empty (read fifo). Due to clock domain crossing inside the SCB block the updated value of this bit is only visible after 2 cycles. The scb_wr_rd_fence() function does 2 dummy writes (to the read-only revision register), and it's called before reading from or writing to the fifos to ensure that subsequent reads of the fifo status bits do not read stale values. As the 2 dummy writes are required in all versions of the ip, the version check is dropped. Fixes: commit 27bce457 ("i2c: img-scb: Add Imagination Technologies I2C SCB driver") Signed-off-by:

commit 850dcc4d upstream. After a packet has been encapsulated by a tunnel we should use the tunnel sockets local multicast loopback flag to control if the encapsulated packet should be locally loopback back. Pass sk into ip_local_out_sk so that in the rare case we are dealing with a tunneled packet whose tunnel destination address is a multicast address the kernel properly decides to loopback this packet. In practice I don't think this matters as ip_queue_xmit is used by tcp, l2tp and sctp none of which I am aware of uses ip level multicasting as they are all point to point communications protocols. Let's fix this before someone uses ip_queue_xmit for a tunnel protocol that does use multicast. Fixes: aad88724 ("ipv4: add a sock pointer to dst->output() path.")

commit 1f35d04a upstream. The iomap[] array has PCIM_IOMAP_MAX (6) elements and not DEVICE_COUNT_RESOURCE (16). This bug was found using a static checker. It may be that the "if (!(mask & (1 << i)))" check means we never actually go past the end of the array in real life. Fixes: ec04b075 ('iomap: implement pcim_iounmap_regions()') Signed-off-by:

commit db1319e1 upstream. Commit d445913c ("usb: ehci-orion: add optional PHY support") added support for optional phys, but devm_phy_optional_get returns -ENOSYS if GENERIC_PHY is not enabled. This causes probe failures, even when there are no phys specified: [ 1.443365] orion-ehci f1058000.usb: init f1058000.usb fail, -38 [ 1.449403] orion-ehci: probe of f1058000.usb failed with error -38 Similar to dwc3, treat -ENOSYS as no phy.

commit a5d42b8c upstream. When the diver is removed and all the resources are deallocated, we should be iterating through the created devices only. Currently, the iteration ends when vivid_devs[i] is NULL. Since the array contains VIVID_MAX_DEVS elements, it will oops if n_devs=VIVID_MAX_DEVS because in that case, no element is NULL.

commit 1f9c6e1b upstream. There were several bugs here. 1) The done label was in the wrong place so we didn't copy any information out when there was no command given. 2) We were using PAGE_SIZE as the size of the buffer instead of "PAGE_SIZE - pos". 3) snprintf() returns the number of characters that would have been printed if there were enough space. If there was not enough space (and we had fixed the memory corruption bug #2) then it would result in an information leak when we do simple_read_from_buffer(). I've changed it to use scnprintf() instead. I also removed the initialization at the start of the function, because I thought it made the code a little more clear.
