2013-12-29x86: Export x86 boot_params to sysfsDave Young1-0/+38
kexec-tools use boot_params for getting the 1st kernel hardware_subarch, the kexec kernel EFI runtime support also needs to read the old efi_info from boot_params. Currently it exists in debugfs which is not a good place for such infomation. Per HPA, we should avoid "sploit debugfs". In this patch /sys/kernel/boot_params are exported, also the setup_data is exported as a subdirectory. kexec-tools is using debugfs for hardware_subarch for a long time now so we're not removing it yet. Structure is like below: /sys/kernel/boot_params |__ data /* boot_params in binary*/ |__ setup_data | |__ 0 /* the first setup_data node */ | | |__ data /* setup_data node 0 in binary*/ | | |__ type /* setup_data type of setup_data node 0, hex string */ [snip] |__ version /* boot protocal version (in hex, "0x" prefixed)*/ Signed-off-by: Dave Young <dyoung@redhat.com> Acked-by: Borislav Petkov <bp@suse.de> Tested-by: Toshi Kani <toshi.kani@hp.com> Signed-off-by: Matt Fleming <matt.fleming@intel.com>
2013-12-29x86: Add xloadflags bit for EFI runtime support on kexecDave Young1-0/+3
Old kexec-tools can not load new kernels. The reason is kexec-tools does not fill efi_info in x86 setup header previously, thus EFI failed to initialize. In new kexec-tools it will by default to fill efi_info and pass other EFI required infomation to 2nd kernel so kexec kernel EFI initialization can succeed finally. To prevent from breaking userspace, add a new xloadflags bit so kexec-tools can check the flag and switch to old logic.

git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata Pull libata fixes from Tejun Heo: "There's one interseting commit - "libata, freezer: avoid block device removal while system is frozen". It's an ugly hack working around a deadlock condition between driver core resume and block layer device removal paths through freezer which was made more reproducible by writeback being converted to workqueue some releases ago. The bug has nothing to do with libata but it's just an workaround which is easy to backport. After discussion, Rafael and I seem to agree that we don't really need kernel freezables - both kthread and workqueue. There are few specific workqueues which constitute PM operations and require freezing, which will be converted to use workqueue_set_max_active() instead. All other kernel freezer uses are planned to be removed, followed by the removal of kthread and workqueue freezer support, hopefully. Others are device-specific fixes. The most notable is the addition of NO_NCQ_TRIM which is used to disable queued TRIM commands to Micro M500 SSDs which otherwise suffers data corruption" * 'for-3.13-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata: libata, freezer: avoid block device removal while system is frozen libata: implement ATA_HORKAGE_NO_NCQ_TRIM and apply it to Micro M500 SSDs libata: disable a disk via libata.force params ahci: bail out on ICH6 before using AHCI BAR ahci: imx: Explicitly clear IMX6Q_GPR13_SATA_MPLL_CLK_EN libata: add ATA_HORKAGE_BROKEN_FPDMA_AA quirk for Seagate Momentus SpinPoint M8

The BIOS does not give any option to disable it at all, so he can't just hide it from the OS via the BIOS.

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs Pull misc keyrings fixes from David Howells: "These break down into five sets: - A patch to error handling in the big_key type for huge payloads. If the payload is larger than the "low limit" and the backing store allocation fails, then big_key_instantiate() doesn't clear the payload pointers in the key, assuming them to have been previously cleared - but only one of them is. Unfortunately, the garbage collector still calls big_key_destroy() when sees one of the pointers with a weird value in it (and not NULL) which it then tries to clean up. - Three patches to fix the keyring type: * A patch to fix the hash function to correctly divide keyrings off from keys in the topology of the tree inside the associative array. This is only a problem if searching through nested keyrings - and only if the hash function incorrectly puts the a keyring outside of the 0 branch of the root node. * A patch to fix keyrings' use of the associative array. The __key_link_begin() function initially passes a NULL key pointer to assoc_array_insert() on the basis that it's holding a place in the tree whilst it does more allocation and stuff. This is only a problem when a node contains 16 keys that match at that level and we want to add an also matching 17th. This should easily be manufactured with a keyring full of keyrings (without chucking any other sort of key into the mix) - except for (a) above which makes it on average adding the 65th keyring. * A patch to fix searching down through nested keyrings, where any keyring in the set has more than 16 keyrings and none of the first keyrings we look through has a match (before the tree iteration needs to step to a more distal node). Test in keyutils test suite: http://git.kernel.org/cgit/linux/kernel/git/dhowells/keyutils.git/commit/?id=8b4ae963ed92523aea18dfbb8cab3f4979e13bd1 - A patch to fix the big_key type's use of a shmem file as its backing store causing audit messages and LSM check failures. This is done by setting S_PRIVATE on the file to avoid LSM checks on the file (access to the shmem file goes through the keyctl() interface and so is gated by the LSM that way). This isn't normally a problem if a key is used by the context that generated it - and it's currently only used by libkrb5. Test in keyutils test suite: http://git.kernel.org/cgit/linux/kernel/git/dhowells/keyutils.git/commit/?id=d9a53cbab42c293962f2f78f7190253fc73bd32e - A patch to add a generated file to .gitignore. - A patch to fix the alignment of the system certificate data such that it it works on s390.

Commit 89ce376c6bdc (drivers/net: Use of_match_ptr() macro in smc91x.c) added minimal device tree support to smc91x, but it's not working on many platforms because of the lack of some key configuration bits.

2013-12-09packet: fix send path when running with proto == 0Daniel Borkmann1-0/+10
Commit e40526cb20b5 introduced a cached dev pointer, that gets hooked into register_prot_hook(), __unregister_prot_hook() to update the device used for the send path. We need to fix this up, as otherwise this will not work with sockets created with protocol = 0, plus with sll_protocol = 0 passed via sockaddr_ll when doing the bind. So instead, assign the pointer directly. The compiler can inline these helper functions automagically. While at it, also assume the cached dev fast-path as likely(), and document this variant of socket creation as it seems it is not widely used (seems not even the author of TX_RING was aware of that in his reference example [1]).

2013-12-05net: davinci_emac: Fix platform data handling and make usable for am3517Tony Lindgren1-1/+1
When booted with device tree, we may still have platform data passed as auxdata. For am3517 this is needed for passing the interrupt_enable and interrupt_disable callbacks that access the omap system control module registers. These callback functions will eventually go away when we have a separate system control module driver. Some of the things that are currently passed as platform data we don't need to set up as device tree properties as they are always the same on am3517. So let's use a new compatible flag for those so we can get those from the device tree match data. Also note that we need to fix setting of phy_dev to NULL instead of an empty string as the code later on uses that to find the first phy on the mdio bus.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes From Tony Lindgren: Some omap related fixes that have come up with people moving to device tree only based booting for omap2+. The series contains a handful of fixes for the igep boards as they were one of the first omap3 boards to jump over completely to device tree based booting. So these can be considered regressions compared to booting igep in legacy mode with board files in v3.12. Also included are few other device tree vs legacy booting regressions: - yet more missing omap3 .dtsi entries that have showed up booting various boards with device tree only - n900 eMMC device tree fix - fixes for beagle USB EHCI - two fixes to make omap2420 MMC work As we're moving omap2+ to be device tree only for v3.14, I'd like to have v3.13 work equally well for legacy based booting and device tree based booting. So there will be likely few more device tree related booting patches trickling in. This series also includes a regression fix for the omap timer posted mode that may wrongly stay on from the bootloader for some SoCs. * tag 'omap-for-v3.13/fixes-against-rc1-take2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: mmc: omap: Fix I2C dependency and make driver usable with device tree mmc: omap: Fix DMA configuration to not rely on device id ARM: dts: omap3-beagle: Fix USB host on beagle boards (for 3.13) ARM: dts: omap3-igep0020: name twl4030 VPLL2 regulator as vdds_dsi ARM: dts: AM33XX IGEP0033: add USB support ARM: dts: AM33XX BASE0033: add 32KBit EEPROM support ARM: dts: AM33XX BASE0033: add pinmux and user led support ARM: dts: AM33XX BASE0033: add pinmux and hdmi node to enable display ARM: dts: omap3-igep0020: Add pinmuxing for DVI output ARM: dts: omap3-igep0020: Add pinmux setup for i2c devices ARM: dts: omap3-igep: Update to use the TI AM/DM37x processor ARM: dts: omap3-igep: Add support for LBEE1USJYC WiFi connected to SDIO ARM: dts: omap3-igep: Fix bus-width for mmc1 ARM: OMAP2+: dss-common: change IGEP's DVI DDC i2c bus ARM: OMAP2+: Disable POSTED mode for errata i103 and i767 ARM: OMAP2+: Fix eMMC on n900 with device tree ARM: OMAP2+: Add fixed regulator to omap2plus_defconfig ARM: OMAP2+: Fix more missing data for omap3.dtsi file Signed-off-by: Olof Johansson <olof@lixom.net>

2013-12-02KEYS: Fix multiple key add into associative arrayDavid Howells1-3/+3
If sufficient keys (or keyrings) are added into a keyring such that a node in the associative array's tree overflows (each node has a capacity N, currently 16) and such that all N+1 keys have the same index key segment for that level of the tree (the level'th nibble of the index key), then assoc_array_insert() calls ops->diff_objects() to indicate at which bit position the two index keys vary. However, __key_link_begin() passes a NULL object to assoc_array_insert() with the intention of supplying the correct pointer later before we commit the change. This means that keyring_diff_objects() is given a NULL pointer as one of its arguments which it does not expect. This results in an oops like the attached. With the previous patch to fix the keyring hash function, this can be forced much more easily by creating a keyring and only adding keyrings to it. Add any other sort of key and a different insertion path is taken - all 16+1 objects must want to cluster in the same node slot. This can be tested by: r=`keyctl newring sandbox @s` for ((i=0; i<=16; i++)); do keyctl newring ring$i $r; done This should work fine, but oopses when the 17th keyring is added. Since ops->diff_objects() is always called with the first pointer pointing to the object to be inserted (ie. the NULL pointer), we can fix the problem by changing the to-be-inserted object pointer to point to the index key passed into assoc_array_insert() instead. Whilst we're at it, we also switch the arguments so that they are the same as for ->compare_object().

MIC user space daemon poll's on sysfs changes. The documentation for sysfs_poll(...) in fs/sysfs/file.c states that "Once poll/select indicates that the value has changed, you need to close and re-open the file, or seek to 0 and read again". This step was missed out earlier and resulted in the daemon spinning continuously rather than getting blocked in 'poll'. This bug was exposed by commit aea585ef8fa65163 introduced as part of sysfs changes in 3.13-rc1. A seek to 0 has been introduced to fix it.

Some features can be configured by the companion I2C chips, which may not be available at the probe time. Fix the issue by returning -EPROBE_DEFER when the MMC controller slots are not configured. While at it, let's also add minimal device tree support so omap24xx platforms can use this driver without legacy mode since we claim to support device tree for mach-omap2 based systems. Although adding the minimal device tree support is not strictly a fix, it does remove one of the last blockers for dropping a bunch of legacy platform data for mach-omap2.

2013-11-25Documentation: gpiolib: document new interfaceAlexandre Courbot6-0/+661
gpiolib now exports a new descriptor-based interface which deprecates the older integer-based one. This patch documents this new interface and also takes the opportunity to brush-up the GPIO documentation a little bit. The new descriptor-based interface follows the same consumer/driver model as many other kernel subsystems (e.g. clock, regulator), so its documentation has similarly been splitted into different files. The content of the former documentation has been reused whenever it made sense; however, some of its content did not apply to the new interface anymore and have this been removed. Likewise, new sections like the mapping of GPIOs to devices have been written from scratch. The deprecated legacy-based documentation is still available, untouched, under Documentation/gpio/gpio-legacy.txt.
