[PATCH] xfs: truncate transaction does not modify the inobt

by Amir Goldstein

From: Brian Foster <bfoster(a)redhat.com> The truncate transaction does not ever modify the inode btree, but includes an associated log reservation. Update xfs_calc_itruncate_reservation() to remove the reservation associated with inobt updates. [Amir: This commit was merged for kernel v4.16 and a twin commit was merged for xfsprogs v4.16. As a result, a small xfs filesystem formatted with features -m rmapbt=1,reflink=1 using mkfs.xfs version >= v4.16 cannot be mounted with kernel < v4.16. For example, xfstests generic/17{1,2,3} format a small fs and when trying to mount it, they fail with an assert on this very demonic line: XFS (vdc): Log size 3075 blocks too small, minimum size is 3717 blocks XFS (vdc): AAIEEE! Log failed size checks. Abort! XFS: Assertion failed: 0, file: src/linux/fs/xfs/xfs_log.c, line: 666 The simple solution for stable kernels is to apply this patch, because mkfs.xfs v4.16 is already in the wild, so we have to assume that xfs filesystems with a "too small" log exist. Regardless, xfsprogs maintainers should also consider reverting the twin patch to stop creating those filesystems for the sake of users with unpatched kernels.] Signed-off-by: Brian Foster <bfoster(a)redhat.com> Reviewed-by: Dave Chinner <dchinner(a)redhat.com> Reviewed-by: Darrick J.

[PATCH V2] x86/speculation: Support Enhanced IBRS on future CPUs

by Sai Praneeth Prakhya

From: Sai Praneeth <sai.praneeth.prakhya(a)intel.com> [ Upstream commit 706d51681d636a0c4a5ef53395ec3b803e45ed4d ] Future Intel processors will support "Enhanced IBRS" which is an "always on" mode i.e. IBRS bit in SPEC_CTRL MSR is enabled once and never disabled. >From the specification [1]: "With enhanced IBRS, the predicted targets of indirect branches executed cannot be controlled by software that was executed in a less privileged predictor mode or on another logical processor. As a result, software operating on a processor with enhanced IBRS need not use WRMSR to set IA32_SPEC_CTRL.IBRS after every transition to a more privileged predictor mode. Software can isolate predictor modes effectively simply by setting the bit once. Software need not disable enhanced IBRS prior to entering a sleep state such as MWAIT or HLT." If Enhanced IBRS is supported by the processor then use it as the preferred spectre v2 mitigation mechanism instead of Retpoline. Intel's Retpoline white paper [2] states: "Retpoline is known to be an effective branch target injection (Spectre variant 2) mitigation on Intel processors belonging to family 6 (enumerated by the CPUID instruction) that do not have support for enhanced IBRS. On processors that support enhanced IBRS, it should be used for mitigation instead of retpoline." The reason why Enhanced IBRS is the recommended mitigation on processors which support it is that these processors also support CET which provides a defense against ROP attacks. Retpoline is very similar to ROP techniques and might trigger false positives in the CET defense. If Enhanced IBRS is selected as the mitigation technique for spectre v2, the IBRS bit in SPEC_CTRL MSR is set once at boot time and never cleared. Kernel also has to make sure that IBRS bit remains set after VMEXIT because the guest might have cleared the bit. This is already covered by the existing x86_spec_ctrl_set_guest() and x86_spec_ctrl_restore_host() speculation control functions. Enhanced IBRS still requires IBPB for full mitigation.

[PATCH] rtc: hctosys: Add missing range error reporting

by Maciej W. Rozycki

Fix an issue with the 32-bit range error path in `rtc_hctosys' where no error code is set and consequently the successful preceding call result from `rtc_read_time' is propagated to `rtc_hctosys_ret'. This in turn makes any subsequent call to `hctosys_show' incorrectly report in sysfs that the system time has been set from this RTC while it has not. Set the error to ERANGE then if we can't express the result due to an overflow. Signed-off-by: Maciej W.

[PATCH] drm/i915/ringbuffer: Delay after EMIT_INVALIDATE for gen4/gen5

by Chris Wilson

Exercising the gpu reloc path strenuously revealed an issue where the updated relocations (from MI_STORE_DWORD_IMM) were not being observed upon execution. After some experiments with adding pipecontrols (a lot of pipecontrols (32) as gen4/5 do not have a bit to wait on earlier pipe controls or even the current on), it was discovered that we merely needed to delay the EMIT_INVALIDATE by several flushes. It is important to note that it is the EMIT_INVALIDATE as opposed to the EMIT_FLUSH that needs the delay as opposed to what one might first expect -- that the delay is required for the TLB invalidation to take effect (one presumes to purge any CS buffers) as opposed to a delay after flushing to ensure the writes have landed before triggering invalidation.

[PATCH] x86/speculation: Support Enhanced IBRS on future CPUs

by Sai Praneeth Prakhya

From: Sai Praneeth <sai.praneeth.prakhya(a)intel.com> [ Upstream commit 706d51681d636a0c4a5ef53395ec3b803e45ed4d ] Changes from upstream: ---------------------- 1. Use bit 30 of word 7 in cpufeatures for X86_FEATURE_IBRS_ENHANCED as bit 29 is now used by L1TF. 2. Fix some trivial line fuzzing. Note: Based on kernel version "Linux 4.18.17" and to be applied on both "Linux 4.18.17" and "Linux 4.14.79". Commit message from upstream: ----------------------------- Future Intel processors will support "Enhanced IBRS" which is an "always on" mode i.e. IBRS bit in SPEC_CTRL MSR is enabled once and never disabled. >From the specification [1]: "With enhanced IBRS, the predicted targets of indirect branches executed cannot be controlled by software that was executed in a less privileged predictor mode or on another logical processor. As a result, software operating on a processor with enhanced IBRS need not use WRMSR to set IA32_SPEC_CTRL.IBRS after every transition to a more privileged predictor mode. Software can isolate predictor modes effectively simply by setting the bit once. Software need not disable enhanced IBRS prior to entering a sleep state such as MWAIT or HLT." If Enhanced IBRS is supported by the processor then use it as the preferred spectre v2 mitigation mechanism instead of Retpoline. Intel's Retpoline white paper [2] states: "Retpoline is known to be an effective branch target injection (Spectre variant 2) mitigation on Intel processors belonging to family 6 (enumerated by the CPUID instruction) that do not have support for enhanced IBRS. On processors that support enhanced IBRS, it should be used for mitigation instead of retpoline." The reason why Enhanced IBRS is the recommended mitigation on processors which support it is that these processors also support CET which provides a defense against ROP attacks. Retpoline is very similar to ROP techniques and might trigger false positives in the CET defense. If Enhanced IBRS is selected as the mitigation technique for spectre v2, the IBRS bit in SPEC_CTRL MSR is set once at boot time and never cleared. Kernel also has to make sure that IBRS bit remains set after VMEXIT because the guest might have cleared the bit. This is already covered by the existing x86_spec_ctrl_set_guest() and x86_spec_ctrl_restore_host() speculation control functions. Enhanced IBRS still requires IBPB for full mitigation.

[PATCH] staging: rtl8723bs: Fix incorrect sense of ether_addr_equal

by Larry Finger

In commit b37f9e1c3801 ("staging: rtl8723bs: Fix lines too long in update_recvframe_attrib()."), the refactoring involved replacing two memcmp() calls with ether_addr_equal() calls. What the author missed is that memcmp() returns false when the two strings are equal, whereas ether_addr_equal() returns true when the two addresses are equal. One side effect of this error is that the strength of an unassociated AP was much stronger than the same AP after association. This bug is reported at bko#201611.

[PATCH v2] backlight: pwm_bl: Fix brightness levels for non-DT case.

by Enric Balletbo i Serra

Commit '88ba95bedb79 ("backlight: pwm_bl: Compute brightness of LED linearly to human eye")' allows the possibility to compute a default brightness table when there isn't the brightness-levels property in the DT. Unfortunately the changes made broke the pwm backlight for the non-DT boards. Usually, the non-DT boards don't pass the brightness levels via platform data, instead, it sets the max_brightness in their platform data and the driver calculates the level without a table. The ofending patch assumed hat when there is no brightness levels table we should create one, but this is clearly wrong for the non-DT case. After this patch the code handles the DT and the non-DT case taking in consideration also if max_brightness is set or not.

Hello, on an mxs machine running a v4.9-rt kernel I saw the following backtrace: [ 25.309794] BUG: sleeping function called from invalid context at kernel/locking/rtmutex.c:987 [ 25.309810] in_atomic(): 1, irqs_disabled(): 128, pid: 221, name: mrp62439d [ 25.309834] CPU: 0 PID: 221 Comm: mrp62439d Not tainted 4.9.109-20180709-1-rt76-00043-g80a57dee2c6b-dirty #43 [ 25.309840] Hardware name: Freescale MXS (Device Tree) [ 25.309913] [<c000fad8>] (unwind_backtrace) from [<c000df34>] (show_stack+0x18/0x1c) [ 25.309957] [<c000df34>] (show_stack) from [<c0042924>] (___might_sleep+0xf8/0x164) [ 25.309996] [<c0042924>] (___might_sleep) from [<c04ec920>] (rt_spin_lock+0x20/0x6c) [ 25.310039] [<c04ec920>] (rt_spin_lock) from [<c02e5a20>] (gpio_to_desc+0x1c/0xbc) [ 25.310076] [<c02e5a20>] (gpio_to_desc) from [<c02ec358>] (mxs_gpio_set_irq_type+0x114/0x194) [ 25.310107] [<c02ec358>] (mxs_gpio_set_irq_type) from [<c00558d8>] (__irq_set_trigger+0x64/0x158) [ 25.310132] [<c00558d8>] (__irq_set_trigger) from [<c0055f74>] (__setup_irq+0x5a8/0x694) [ 25.310156] [<c0055f74>] (__setup_irq) from [<c0056408>] (request_threaded_irq+0xe4/0x18c) [ 25.310187] [<c0056408>] (request_threaded_irq) from [<c02e8650>] (gpio_ioctl+0x304/0x680) [ 25.310217] [<c02e8650>] (gpio_ioctl) from [<c01476a4>] (do_vfs_ioctl+0x98/0x970) [ 25.310241] [<c01476a4>] (do_vfs_ioctl) from [<c0147fb8>] (SyS_ioctl+0x3c/0x64) [ 25.310264] [<c0147fb8>] (SyS_ioctl) from [<c000a4d8>] (__sys_trace_return+0x0/0x10) The problem is that __irq_set_trigger is called in atomic context (even on rt) and mxs_gpio_set_irq_type calls gpio_get_value which takes the (sleeping on rt) gpio_lock. I didn't test 833eacc7b5913da9896bacd30db7d490aa777868 yet (I used val = readl(port->base + PINCTRL_DIN(port)) & pin_mask; instead) but this commit should have the same effect. Can you please backport this? (There are maybe some more similar problems that were introduced in v4.5-rc1 / 0f4630f3720e7e, I didn't check these though.)
