2017-10-08ttpci: address stringop overflow warningArnd Bergmann
commit 69d3973af1acd4c0989ec8218c05f12d303cd7cf upstream. gcc-7.0.1 warns about old code in ttpci: In file included from drivers/media/pci/ttpci/av7110.c:63:0: In function 'irdebi.isra.2', inlined from 'start_debi_dma' at drivers/media/pci/ttpci/av7110.c:376:3, inlined from 'gpioirq' at drivers/media/pci/ttpci/av7110.c:659:3: drivers/media/pci/ttpci/av7110_hw.h:406:3: warning: 'memcpy': specified size between 18446744071562067968 and 18446744073709551615 exceeds maximum object size 9223372036854775807 [-Wstringop-overflow=] memcpy(av7110->debi_virt, (char *) &res, count); In function 'irdebi.isra.2', inlined from 'start_debi_dma' at drivers/media/pci/ttpci/av7110.c:376:3, inlined from 'gpioirq' at drivers/media/pci/ttpci/av7110.c:668:3: drivers/media/pci/ttpci/av7110_hw.h:406:3: warning: 'memcpy': specified size between 18446744071562067968 and 18446744073709551615 exceeds maximum object size 9223372036854775807 [-Wstringop-overflow=] memcpy(av7110->debi_virt, (char *) &res, count); Apparently, 'count' can be negative here, which will then get turned into a giant size argument for memcpy. Changing the sizes to 'unsigned int' instead seems safe as we already check for maximum sizes, and it also simplifies the code a bit.

[ Upstream commit d85fc67dd11e9a32966140677d4d6429ca540b25 ] Without this patch, failed probe would not free resources like irq. ata port tdev object currently hold a reference to the ata port object. Therefore the ata port object release function will not get called until the ata_tport_release is called. But that would never happen, releasing the last reference of ata port dev is done by scsi_host_release, which is called by ata_host_release when the ata port object is released. The ata device objects actually do not need to explicitly hold a reference to their real counterpart, given the transport objects are the children of these objects and device_add() is call for each child. We know the parent will not be deleted until we call the child's device_del().

2017-10-08xfs: remove kmem_zalloc_greedyDarrick J. Wong
[ Upstream commit 08b005f1333154ae5b404ca28766e0ffb9f1c150 ] The sole remaining caller of kmem_zalloc_greedy is bulkstat, which uses it to grab 1-4 pages for staging of inobt records. The infinite loop in the greedy allocation function is causing hangs[1] in generic/269, so just get rid of the greedy allocator in favor of kmem_zalloc_large. This makes bulkstat somewhat more likely to ENOMEM if there's really no pages to spare, but eliminates a source of hangs.

[ Upstream commit ae5c682113f9f94cc5e76f92cf041ee624c173ee ] The helper->expect_class_max must be set to the total number of expect_policy minus 1, since we will use the statement "if (class > helper->expect_class_max)" to validate the CTA_EXPECT_CLASS attr in ctnetlink_alloc_expect. So for compatibility, set the helper->expect_class_max to the NFCTH_POLICY_SET_NUM attr's value minus 1. Also: it's invalid when the NFCTH_POLICY_SET_NUM attr's value is zero. 1. this will result "expect_policy = kzalloc(0, GFP_KERNEL);"; 2. we cannot set the helper->expect_class_max to a proper value. So if nla_get_be32(tb[NFCTH_POLICY_SET_NUM]) is zero, report -EINVAL to the userspace.

2017-10-08MIPS: IRQ Stack: Unwind IRQ stack onto task stackMatt Redfearn
[ Upstream commit db8466c581cca1a08b505f1319c3ecd246f16fa8 ] When the separate IRQ stack was introduced, stack unwinding only proceeded as far as the top of the IRQ stack, leading to kernel backtraces being less useful, lacking the trace of what was interrupted. Fix this by providing a means for the kernel to unwind the IRQ stack onto the interrupted task stack. The processor state is saved to the kernel task stack on interrupt. The IRQ_STACK_START macro reserves an unsigned long at the top of the IRQ stack where the interrupted task stack pointer can be saved. After the active stack is switched to the IRQ stack, save the interrupted tasks stack pointer to the reserved location. Fix the stack unwinding code to look for the frame being the top of the IRQ stack and if so get the next frame from the saved location. The existing test does not work with the separate stack since the ra is no longer pointed at ret_from_{irq,exception}. The test to stop unwinding the stack 32 bytes from the top of a stack must be modified to allow unwinding to continue up to the location of the saved task stack pointer when on the IRQ stack. The low / high marks of the stack are set depending on whether the sp is on an irq stack or not.

2017-10-08netfilter: invoke synchronize_rcu after set the _hook_ to NULLLiping Zhang
[ Upstream commit 3b7dabf029478bb80507a6c4500ca94132a2bc0b ] Otherwise, another CPU may access the invalid pointer. For example: CPU0 CPU1 - rcu_read_lock(); - pfunc = _hook_; _hook_ = NULL; - mod unload - - pfunc(); // invalid, panic - rcu_read_unlock(); So we must call synchronize_rcu() to wait the rcu reader to finish. Also note, in nf_nat_snmp_basic_fini, synchronize_rcu() will be invoked by later nf_conntrack_helper_unregister, but I'm inclined to add a explicit synchronize_rcu after set the nf_nat_snmp_hook to NULL. Depend on such obscure assumptions is not a good idea. Last, in nfnetlink_cttimeout, we use kfree_rcu to free the time object, so in cttimeout_exit, invoking rcu_barrier() is not necessary at all, remove it too.

[ Upstream commit 37e1df8c95e2c8a57c77eafc097648f6e40a60ff ] This starts to handle probe deferrals on regulators and clocks on the ASoC DAPM. I came to this patch after audio stopped working on Ux500 ages ago and I finally looked into it to see what is wrong. I had messages like this in the console since a while back: ab8500-codec.0: ASoC: Failed to request audioclk: -517 ab8500-codec.0: ASoC: Failed to create DAPM control audioclk ab8500-codec.0: Failed to create new controls -12 snd-soc-mop500.0: ASoC: failed to instantiate card -12 snd-soc-mop500.0: Error: snd_soc_register_card failed (-12)! snd-soc-mop500: probe of snd-soc-mop500.0 failed with error -12 Apparently because the widget table for the codec looks like this (sound/soc/codecs/ab8500-codec.c): static const struct snd_soc_dapm_widget ab8500_dapm_widgets[] = { /* Clocks */ SND_SOC_DAPM_CLOCK_SUPPLY("audioclk"), /* Regulators */ SND_SOC_DAPM_REGULATOR_SUPPLY("V-AUD", 0, 0), SND_SOC_DAPM_REGULATOR_SUPPLY("V-AMIC1", 0, 0), SND_SOC_DAPM_REGULATOR_SUPPLY("V-AMIC2", 0, 0), SND_SOC_DAPM_REGULATOR_SUPPLY("V-DMIC", 0, 0), So when we call snd_soc_register_codec() and any of these widgets get a deferred probe we do not get an -EPROBE_DEFER (-517) back as we should and instead we just fail. Apparently the code assumes that clocks and regulators must be available at this point and not defer. After this patch it rather looks like this: ab8500-codec.0: Failed to create new controls -517 snd-soc-mop500.0: ASoC: failed to instantiate card -517 snd-soc-mop500.0: Error: snd_soc_register_card failed (-517)!

I want an indication from the maintainers whether I should just go in and augment all these call sites, or if deferred probe is frowned upon when it leads to this much overhead.

[ Upstream commit fa2849e9649b5180ffc4cb3c3b005261c403093a ] For some reason the axp288_adc driver was modifying the AXP288_ADC_TS_PIN_CTRL register, changing bits 0-1 depending on whether the GP_ADC channel or another channel was written. These bits control when a bias current is send to the TS_PIN, the GP_ADC has its own pin and a separate bit in another register to control the bias current. Not only does changing when to enable the TS_PIN bias current (always or only when sampling) when reading the GP_ADC make no sense at all, the code is modifying these bits is writing the entire register, assuming that all the other bits have their default value. So if the firmware has configured a different bias-current for either pin, then that change gets clobbered by the write, likewise if the firmware has set bit 2 to indicate that the battery has no thermal sensor, this will get clobbered by the write. This commit fixes all this, by simply removing all writes to the AXP288_ADC_TS_PIN_CTRL register, they are not needed to read the GP_ADC pin, and can actually be harmful.

This commit switches to checking the vbus-valid bit instead, which is only 1 when both vbus is present and the vbus-path is enabled in the vbus-path control register (the vbus-path gets disabled when a usb-host cable is detected, to avoid the pmic drawing power from the 5v boost converter).

[ Upstream commit 69b97cf6dbce7403845a28bbc75d57f5be7b12ac ] Whenever the igb driver detects the result of a read operation returns a value composed only by F's (like 0xFFFFFFFF), it will detach the net_device, clear the hw_addr pointer and warn to the user that adapter's link is lost - those steps happen on igb_rd32(). In case a PCI error happens on Power architecture, there's a recovery mechanism called EEH, that will reset the PCI slot and call driver's handlers to reset the adapter and network functionality as well. We observed that once hw_addr is NULL after the error is detected on igb_rd32(), it's never assigned back, so in the process of resetting the network functionality we got a NULL pointer dereference in both igb_configure_tx_ring() and igb_configure_rx_ring().

[ Upstream commit 3f00f4d8f083bc61005d0a1ef592b149f5c88bbd ] When clearing the .bss section in kernel_entry we do so using LONG_S instructions, and branch whilst the current write address doesn't equal the end of the .bss section minus the size of a long integer. The .bss section always begins at a long-aligned address and we always increment the write pointer by the size of a long integer - we therefore rely upon the .bss section ending at a long-aligned address. If this is not the case then the long-aligned write address can never be equal to the non-long-aligned end address & we will continue to increment past the end of the .bss section, attempting to zero the rest of memory. Despite this requirement that .bss end at a long-aligned address we pass 0 as the end alignment requirement to the BSS_SECTION macro and thus don't guarantee any particular alignment, allowing us to hit the error condition described above. Fix this by instead passing 8 bytes as the end alignment argument to the BSS_SECTION macro, ensuring that the end of the .bss section is always at least long-aligned.
