The only thing that efivarfs does to enforce a valid filename is ensure that the name isn't too short. We need to strongly sanitise any filenames, not least because variable creation is delayed until efivarfs_file_write(), which means we can't rely on the firmware to inform us of an invalid name, because if the file is never written to we'll never know it's invalid. Perform a couple of steps before agreeing to create a new file, * hex_to_bin() returns a value indicating whether or not it was able to convert its arguments to a binary representation - we should check it. * Ensure that the GUID portion of the filename is the correct length and format. * The variable name portion of the filename needs to be at least one character in size.

When initrd file didn't put at the same place with stub kernel, we need give the file path of initrd, but need use backslash to separate directory and file. It's not friendly to unix/linux user, and not so intuitive for bootloader forward paramters to efi stub kernel by chainloading. This patch add support to handle_ramdisks for allow slash in file path of initrd, it convert slash to backlash when parsing path. In additional, this patch also separates print code of efi_char16_t from efi_printk, and print out the path/filename of initrd when failed to open initrd file. It's good for debug and discover typo.

Pull x86 EFI fixes from Peter Anvin: "This is a collection of fixes for the EFI support. The controversial bit here is a set of patches which bumps the boot protocol version as part of fixing some serious problems with the EFI handover protocol, used when booting under EFI using a bootloader as opposed to directly from EFI. These changes should also make it a lot saner to support cross-mode 32/64-bit EFI booting in the future. Getting these changes into 3.8 means we avoid presenting an inconsistent ABI to bootloaders. Other changes are display detection and fixing efivarfs." * 'x86-efi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, efi: remove attribute check from setup_efi_pci x86, build: Dynamically find entry points in compressed startup code x86, efi: Fix PCI ROM handing in EFI boot stub, in 32-bit mode x86, efi: Fix 32-bit EFI handover protocol entry point x86, efi: Fix display detection in EFI boot stub x86, boot: Define the 2.12 bzImage boot protocol x86/boot: Fix minor fd leakage in tools/relocs.c x86, efi: Set runtime_version to the EFI spec revision x86, efi: fix 32-bit warnings in setup_efi_pci() efivarfs: Delete dentry from dcache in efivarfs_file_write() efivarfs: Never return ENOENT from firmware efi, x86: Pass a proper identity mapping in efi_call_phys_prelog efivarfs: Drop link count of the right inode

Pull console lockdep checking revert from Dave Airlie. The lockdep splat this showed was interesting, but it's very very old, and we won't be fixing it until 3.9.

It has been reported that running this driver on some Samsung laptops with EFI can cause those machines to become bricked as detailed in the following report, https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557 There have also been reports of this driver causing Machine Check Exceptions on recent EFI-enabled Samsung laptops, https://bugzilla.kernel.org/show_bug.cgi?id=47121 So disable it if booting from EFI since this driver relies on grovelling around in the BIOS memory map which isn't going to work.

Originally 'efi_enabled' indicated whether a kernel was booted from EFI firmware. Over time its semantics have changed, and it now indicates whether or not we are booted on an EFI machine with bit-native firmware, e.g. 64-bit kernel with 64-bit firmware. The immediate motivation for this patch is the bug report at, https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557 which details how running a platform driver on an EFI machine that is designed to run under BIOS can cause the machine to become bricked. Also, the following report, https://bugzilla.kernel.org/show_bug.cgi?id=47121 details how running said driver can also cause Machine Check Exceptions. Drivers need a new means of detecting whether they're running on an EFI machine, as sadly the expression, if (!efi_enabled) hasn't been a sufficient condition for quite some time. Users actually want to query 'efi_enabled' for different reasons - what they really want access to is the list of available EFI facilities. For instance, the x86 reboot code needs to know whether it can invoke the ResetSystem() function provided by the EFI runtime services, while the ACPI OSL code wants to know whether the EFI config tables were mapped successfully. There are also checks in some of the platform driver code to simply see if they're running on an EFI machine (which would make it a bad idea to do BIOS-y things). This patch is a prereq for the samsung-laptop fix patch.

Functions called from a driver probe() method must not be marked __init, because they may get called after the init phase is done, when the device shows up late, or because of deferred probing. Without this patch, building exynos_defconfig results in multiple warnings like: WARNING: drivers/pinctrl/built-in.o(.text+0x51bc): Section mismatch in reference from the function exynos5440_pinctrl_probe() to the function .init.text:exynos5440_gpiolib_register() The function exynos5440_pinctrl_probe() references the function __init exynos5440_gpiolib_register(). This is often because exynos5440_pinctrl_probe lacks a __init annotation or the annotation of exynos5440_gpiolib_register is wrong.

It looks like the original commit that copied the rom contents from efi always copied the rom, and the fixup in setup_efi_pci from commit 886d751a ("x86, efi: correct precedence of operators in setup_efi_pci") broke that. This resulted in macbook pro's no longer finding the rom images, and thus not being able to use the radeon card any more. The solution is to just remove the check for now, and always copy the rom if available.

For non-snoop mode, we fiddle with the page attributes of CORB/RIRB and the position buffer, but also the ring buffers. The problem is that the current code blindly assumes that the buffer is contiguous. However, the ring buffers may be SG-buffers, thus a wrong vmapped address is passed there, leading to Oops.

With lazy interrupt, we always call __check_irq_replaysome with decrementers_next_tb to check if we need to replay timer interrupt. So in hotplug case we also need to set decrementers_next_tb as MAX to make sure __check_irq_replay don't replay timer interrupt when return as we expect, otherwise we'll trap here infinitely.

commit f96972f2 "kernel/sys.c: call disable_nonboot_cpus() in kernel_restart()" added a call to disable_nonboot_cpus() on kernel_restart(), which tries to shutdown all the CPUs except the first one. The issue with the PA Semi, is that it does not support CPU hotplug. When the call is made to __cpu_down(), it calls the notifiers CPU_DOWN_PREPARE, and then tries to take the CPU down. One of the notifiers to the CPU hotplug code, is the cpufreq. The DOWN_PREPARE will call __cpufreq_remove_dev() which calls cpufreq_driver->exit. The PA Semi exit handler unmaps regions of I/O that is used by an interrupt that goes off constantly (system_reset_common, but it goes off during normal system operations too). I'm not sure exactly what this interrupt does. Running a simple function trace, you can see it goes off quite a bit: # tracer: function # # TASK-PID CPU# TIMESTAMP FUNCTION # | | | | | <idle>-0 [001] 1558.859363: .pasemi_system_reset_exception <-.system_reset_exception <idle>-0 [000] 1558.860112: .pasemi_system_reset_exception <-.system_reset_exception <idle>-0 [000] 1558.861109: .pasemi_system_reset_exception <-.system_reset_exception <idle>-0 [001] 1558.861361: .pasemi_system_reset_exception <-.system_reset_exception <idle>-0 [000] 1558.861437: .pasemi_system_reset_exception <-.system_reset_exception When the region is unmapped, the system crashes with: Disabling non-boot CPUs ...

Commit fb595814 removed xfs_flushinval_pages() and changed its callers to use filemap_write_and_wait() and truncate_pagecache_range() directly. But in xfs_swap_extents() this change accidental switched the argument for 'tip' to 'ip'. This patch switches it back to 'tip' Signed-off-by: Torsten Kaiser <just.for.lkml@googlemail.com> Reviewed-by: Ben Myers <bpm@sgi.com> Signed-off-by: Ben Myers <bpm@sgi.com>

Pull IOMMU fix from Joerg Roedel: "One fix for the AMD IOMMU driver to work around broken BIOSes found in the field. Some BIOSes forget to enable a workaround for a hardware problem which might cause the IOMMU to stop working under high load conditions. The fix makes sure this workaround is enabled." * tag 'iommu-fixes-v3.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: IOMMU, AMD Family15h Model10-1Fh erratum 746 Workaround

Pull MFD fixes from Samuel Ortiz: "This is the first pull request for MFD fixes for 3.8 We have some build failure fixes (twl4030, vexpress, abx500 and tps65910), some actual runtime oops and lockup fixes (rtsx, da9052), and some more hypothetical NULL pointers dereferences fixes for pcf50633 and max776xx. Then we also have additional rtsx fixes for a correct switch output voltage and clock divider correctness for rtl8411 (rtsx driver), and irqdomain fix for db8550-prcmu, and some more cosmetic fixes for arizona and wm5102." * tag 'mfd-for-linus-3.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6: mfd: rtsx: Fix oops when rtsx_pci_sdmmc is not probed mfd: wm5102: Fix definition of WM5102_MAX_REGISTER mfd: twl4030: Don't warn about uninitialized return code mfd: da9052/53 lockup fix mfd: rtsx: Add clock divider hook mmc: rtsx: Call MFD hook to switch output voltage mfd: rtsx: Add output voltage switch hook mfd: Fix compile errors and warnings when !CONFIG_AB8500_BM mfd: vexpress: Export global functions to fix build error mfd: arizona: Check errors from regcache_sync() mfd: tc3589x: Use simple irqdomain mfd: pcf50633: Init pcf->dev before using it mfd: max77693: Init max77693->dev before using it mfd: max77686: Init max77686->dev before using it mfd: db8500-prcmu: Fix irqdomain usage mfd: tps65910: Select REGMAP_IRQ in Kconfig to fix build error mfd: arizona: Disable control interface reporting for WM5102 and WM5110

Pull networking updates from David Miller: "Much more accumulated than I would have liked due to an unexpected bout with a nasty flu: 1) AH and ESP input don't set ECN field correctly because the transport head of the SKB isn't set correctly, fix from Li RongQing. 2) If netfilter conntrack zones are disabled, we can return an uninitialized variable instead of the proper error code. Fix from Borislav Petkov. 3) Fix double SKB free in ath9k driver beacon handling, from Felix Feitkau. 4) Remove bogus assumption about netns cleanup ordering in nf_conntrack, from Pablo Neira Ayuso. 5) Remove a bogus BUG_ON in the new TCP fastopen code, from Eric Dumazet. It uses spin_is_locked() in it's test and is therefore unsuitable for UP. 6) Fix SELINUX labelling regressions added by the tuntap multiqueue changes, from Paul Moore. 7) Fix CRC errors with jumbo frame receive in tg3 driver, from Nithin Nayak Sujir. 8) CXGB4 driver sets interrupt coalescing parameters only on first queue, rather than all of them. Fix from Thadeu Lima de Souza Cascardo. 9) Fix regression in the dispatch of read/write registers in dm9601 driver, from Tushar Behera. 10) ipv6_append_data miscalculates header length, from Romain KUNTZ. 11) Fix PMTU handling regressions on ipv4 routes, from Steffen Klassert, Timo Teräs, and Julian Anastasov. 12) In 3c574_cs driver, add necessary parenthesis to "x << y & z" expression. From Nickolai Zeldovich. 13) macvlan_get_size() causes underallocation netlink message space, fix from Eric Dumazet. 14) Avoid division by zero in xfrm_replay_advance_bmp(), from Nickolai Zeldovich. Amusingly the zero check was already there, we were just performing it after the modulus :-) 15) Some more splice bug fixes from Eric Dumazet, which fix things mostly eminating from how we now more aggressively use high-order pages in SKBs. 16) Fix size calculation bug when freeing hash tables in the IPSEC xfrm code, from Michal Kubecek. 17) Fix PMTU event propagation into socket cached routes, from Steffen Klassert. 18) Fix off by one in TX buffer release in netxen driver, from Eric Dumazet. 19) Fix rediculous memory allocation requirements introduced by the tuntap multiqueue changes, from Jason Wang. 20) Remove bogus AMD platform workaround in r8169 driver that causes major problems in normal operation, from Timo Teräs. 21) virtio-net set affinity and select queue don't handle discontiguous cpu numbers properly, fix from Wanlong Gao. 22) Fix a route refcounting issue in loopback driver, from Eric Dumazet. There's a similar fix coming that we might add to the macvlan driver as well. 23) Fix SKB leaks in batman-adv's distributed arp table code, from Matthias Schiffer. 24) r8169 driver gives descriptor ownership back the hardware before we're done reading the VLAN tag out of it, fix from Francois Romieu. 25) Checksums not calculated properly in GRE tunnel driver fix from Pravin B Shelar. 26) Fix SCTP memory leak on namespace exit." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (101 commits) dm9601: support dm9620 variant SCTP: Free the per-net sysctl table on net exit. v2 net: phy: icplus: fix broken INTR pin settings net: phy: icplus: Use the RGMII interface mode to configure clock delays IP_GRE: Fix kernel panic in IP_GRE with GRE csum. sctp: set association state to established in dupcook_a handler ip6mr: limit IPv6 MRT_TABLE identifiers r8169: fix vlan tag read ordering. net: cdc_ncm: use IAD provided by the USB core batman-adv: filter ARP packets with invalid MAC addresses in DAT batman-adv: check for more types of invalid IP addresses in DAT batman-adv: fix skb leak in batadv_dat_snoop_incoming_arp_reply() net: loopback: fix a dst refcounting issue virtio-net: reset virtqueue affinity when doing cpu hotplug virtio-net: split out clean affinity function virtio-net: fix the set affinity bug when CPU IDs are not consecutive can: pch_can: fix invalid error codes can: ti_hecc: fix invalid error codes can: c_can: fix invalid error codes r8169: remove the obsolete and incorrect AMD workaround ...
