[PATCH] selftests: Fix test errors related to lib.mk khdr target

by shuah＠kernel.org

From: Shuah Khan <shuah(a)kernel.org> Commit b2d35fa5fc80 ("selftests: add headers_install to lib.mk") added khdr target to run headers_install target from the main Makefile. The logic uses KSFT_KHDR_INSTALL and top_srcdir as controls to initialize variables and include files to run headers_install from the top level Makefile. There are a few problems with this logic. 1. Exposes top_srcdir to all tests 2. Common logic impacts all tests 3. Uses KSFT_KHDR_INSTALL, top_srcdir, and khdr in an adhoc way. Tests add "khdr" dependency in their Makefiles to TEST_PROGS_EXTENDED in some cases, and STATIC_LIBS in other cases. This makes this framework confusing to use. The common logic that runs for all tests even when KSFT_KHDR_INSTALL isn't defined by the test. top_srcdir is initialized to a default value when test doesn't initialize it. It works for all tests without a sub-dir structure and tests with sub-dir structure fail to build. e.g: make -C sparc64/drivers/ or make -C drivers/dma-buf ../../lib.mk:20: ../../../../scripts/subarch.include: No such file or directory make: *** No rule to make target '../../../../scripts/subarch.include'. Stop. There is no reason to require all tests to define top_srcdir and there is no need to require tests to add khdr dependency using adhoc changes to TEST_* and other variables. Fix it with a consistent use of KSFT_KHDR_INSTALL and top_srcdir from tests that have the dependency on headers_install. Change common logic to include khdr target define and "all" target with dependency on khdr when KSFT_KHDR_INSTALL is defined. Only tests that have dependency on headers_install have to define just the KSFT_KHDR_INSTALL, and top_srcdir variables and there is no need to specify khdr dependency in the test Makefiles.

[PATCH] mtd: rawnand: Pass the parent of pdev to dma_request_chan()

Commit e1e6255c311b ("mtd: rawnand: omap2: convert driver to nand_scan()") moved part of the init code in the ->attach_chip hook and at the same time changed the struct device object passed to dma_request_chan() (&pdev->dev instead of pdev->dev.parent).

Security fixes for 4.4

by Ben Hutchings

I've backported a number of fixes for security issues affecting 4.4- stable. All of these are already fixed in the newer stable branches. For the BPF fix, I verified that the self-tests (taken from 4.14) didn't regress and temporarily added logging to check that the mitigation is applied when needed. For the KVM changes, I verified that IBPB/IBRS are now exposed to and used by a guest on Intel hardware. I also verified that the current self-tests for timers, usercopy and vm didn't regress.

patch "iio: adc: qcom-spmi-adc5: Initialize prescale properly" added to staging-next

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled iio: adc: qcom-spmi-adc5: Initialize prescale properly to my staging git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git in the staging-next branch.

If you have any questions about this process, please let me know. >From db23d88756abd38e0995ea8449d0025b3de4b26b Mon Sep 17 00:00:00 2001 From: Evan Green <evgreen(a)chromium.org> Date: Tue, 4 Dec 2018 11:14:19 -0800 Subject: iio: adc: qcom-spmi-adc5: Initialize prescale properly adc5_get_dt_data uses a local, prop, feeds it to adc5_get_dt_channel_data, and then puts the result into adc->chan_props. The problem is adc5_get_dt_channel_data may not initialize that structure fully, so a garbage value is used for prescale if the optional "qcom,pre-scaling" is not defined in DT. adc5_read_raw then uses this as an array index, generating a crash that looks like this: [ 6.683186] Unable to handle kernel paging request at virtual address ffffff90e78c7964 Call trace: qcom_vadc_scale_code_voltage_factor+0x74/0x104 qcom_vadc_scale_hw_calib_die_temp+0x20/0x60 qcom_adc5_hw_scale+0x78/0xa4 adc5_read_raw+0x3d0/0x65c iio_channel_read+0x240/0x30c iio_read_channel_processed+0x10c/0x150 qpnp_tm_get_temp+0xc0/0x40c of_thermal_get_temp+0x7c/0x98 thermal_zone_get_temp+0xac/0xd8 thermal_zone_device_update+0xc0/0x38c qpnp_tm_probe+0x624/0x81c platform_drv_probe+0xe4/0x11c really_probe+0x188/0x3fc driver_probe_device+0xb8/0x188 __device_attach_driver+0x114/0x180 bus_for_each_drv+0xd8/0x118 __device_attach+0x180/0x27c device_initial_probe+0x20/0x2c bus_probe_device+0x78/0x124 deferred_probe_work_func+0xfc/0x138 process_one_work+0x3d8/0x8b0 process_scheduled_works+0x48/0x6c worker_thread+0x488/0x7cc kthread+0x24c/0x264 ret_from_fork+0x10/0x18 Unfortunately, when I went to add the initializer for this and tried to boot it, my machine shut down immediately, complaining that it was hotter than the sun. It appears that adc5_chans_pmic and adc5_chans_rev2 were initializing prescale_index as if it were directly a divisor, rather than the index into adc5_prescale_ratios that it is. Fix the uninitialized value, and change the static initialization to use indices into adc5_prescale_ratios.

[PATCH] arm64: kvm: Avoid setting the upper 32 bits of VTCR_EL2 to 1

by Will Deacon

Although bit 31 of VTCR_EL2 is RES1, we inadvertently end up setting all of the upper 32 bits to 1 as well because we define VTCR_EL2_RES1 as signed, which is sign-extended when assigning to kvm->arch.vtcr. Lucky for us, the architecture currently treats these upper bits as RES0 so, whilst we've been naughty, we haven't set fire to anything yet.
