Patch "[Variant 3/Meltdown] arm64: capabilities: Handle duplicate entries for a capability" has been added to the 4.14-stable tree

This is a note to let you know that I've just added the patch titled [Variant 3/Meltdown] arm64: capabilities: Handle duplicate entries for a capability to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: arm64-capabilities-handle-duplicate-entries-for-a-capability.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Wed Feb 14 14:44:54 CET 2018 From: Suzuki K Poulose <suzuki.poulose(a)arm.com> Date: Tue, 9 Jan 2018 16:12:18 +0000 Subject: [Variant 3/Meltdown] arm64: capabilities: Handle duplicate entries for a capability From: Suzuki K Poulose <suzuki.poulose(a)arm.com> Commit 67948af41f2e upstream. Sometimes a single capability could be listed multiple times with differing matches(), e.g, CPU errata for different MIDR versions. This breaks verify_local_cpu_feature() and this_cpu_has_cap() as we stop checking for a capability on a CPU with the first entry in the given table, which is not sufficient. Make sure we run the checks for all entries of the same capability. We do this by fixing __this_cpu_has_cap() to run through all the entries in the given table for a match and reuse it for verify_local_cpu_feature().

Function identifiers are a 32bit, unsigned quantity. But we never tell so to the compiler, resulting in the following: 4ac: b26187e0 mov x0, #0xffffffff80000001 We thus rely on the firmware narrowing it for us, which is not always a reasonable expectation.

Patch "[Variant 2/Spectre-v2] arm/arm64: smccc: Implement SMCCC v1.1 inline primitive" has been added to the 4.14-stable tree

One of the major improvement of SMCCC v1.1 is that it only clobbers the first 4 registers, both on 32 and 64bit. This means that it becomes very easy to provide an inline version of the SMC call primitive, and avoid performing a function call to stash the registers that would otherwise be clobbered by SMCCC v1.0.

Patch "[Variant 2/Spectre-v2] arm/arm64: KVM: Implement PSCI 1.0 support" has been added to the 4.14-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled [Variant 2/Spectre-v2] arm/arm64: KVM: Implement PSCI 1.0 support to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: arm-arm64-kvm-implement-psci-1.0-support.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Wed Feb 14 14:44:54 CET 2018 From: Marc Zyngier <marc.zyngier(a)arm.com> Date: Tue, 6 Feb 2018 17:56:11 +0000 Subject: [Variant 2/Spectre-v2] arm/arm64: KVM: Implement PSCI 1.0 support From: Marc Zyngier <marc.zyngier(a)arm.com> Commit 58e0b2239a4d upstream. PSCI 1.0 can be trivially implemented by providing the FEATURES call on top of PSCI 0.2 and returning 1.0 as the PSCI version. We happily ignore everything else, as they are either optional or are clarifications that do not require any additional change. PSCI 1.0 is now the default until we decide to add a userspace selection API.

[PATCH] ubifs: Fix synced_i_size calculation for xattr inodes

by Richard Weinberger

In ubifs_jnl_update() we sync parent and child inodes to the flash, in case of xattrs, the parent inode (AKA host inode) has a non-zero data_len. Therefore we need to adjust synced_i_size too. This issue was reported by ubifs self tests unter a xattr related work load. UBIFS error (ubi0:0 pid 1896): dbg_check_synced_i_size: ui_size is 4, synced_i_size is 0, but inode is clean UBIFS error (ubi0:0 pid 1896): dbg_check_synced_i_size: i_ino 65, i_mode 0x81a4, i_size 4 Cc: <stable(a)vger.kernel.org> Fixes: 1e51764a3c2a ("UBIFS: add new flash file system") Signed-off-by: Richard Weinberger <richard(a)nod.at> --- fs/ubifs/journal.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/fs/ubifs/journal.c b/fs/ubifs/journal.c index 04c4ec6483e5..e3e1e093db81 100644 --- a/fs/ubifs/journal.c +++ b/fs/ubifs/journal.c @@ -664,6 +664,8 @@ int ubifs_jnl_update(struct ubifs_info *c, const struct inode *dir, finish_reservation(c); spin_lock(&ui->ui_lock); ui->synced_i_size = ui->ui_size; + if (xent) + host_ui->synced_i_size = host_ui->ui_size; spin_unlock(&ui->ui_lock); mark_inode_clean(c, ui); mark_inode_clean(c, host_ui); -- 2.13.6

[PATCH for v3.2 00/12] v4l2-compat-ioctl32.c: remove set_fs(KERNEL_DS)

by Hans Verkuil

From: Hans Verkuil <hans.verkuil(a)cisco.com> This patch series fixes a number of bugs and culminates in the removal of the set_fs(KERNEL_DS) call in v4l2-compat-ioctl32.c. This was tested with a VM running 3.2, the vivi driver (a poor substitute for the much improved vivid driver that's available in later kernels, but it's the best I had) since that emulates the more common V4L2 ioctls that need to pass through v4l2-compat-ioctl32.c) and the 32-bit v4l2-compliance + 32-bit v4l2-ctl utilities that together exercised the most common ioctls. Most of the v4l2-compat-ioctl32.c do cleanups and fix subtle issues that v4l2-compliance complained about. The purpose is to 1) make it easy to verify that the final patch didn't introduce errors by first eliminating errors caused by other known bugs, and 2) keep the final patch at least somewhat readable.

[PATCH for v3.16 00/14] v4l2-compat-ioctl32.c: remove set_fs(KERNEL_DS)

So, either we do: cprman_write(cprman, data->cm_ctrl_reg, CM_PLL_ANARST); cprman_write(cprman, data->a2w_ctrl_reg, cprman_read(cprman, data->a2w_ctrl_reg) | A2W_PLL_CTRL_PWRDN); or we cache the pdiv/ndiv values in struct bcm2835_pll and only apply them in bcm2835_pll_on(). I'd recommend going for the former to keep the changes easily backportable to older kernels. > > How about we do that, instead? > > > @@ -640,6 +643,10 @@ static int bcm2835_pll_on(struct clk_hw *hw) > > cpu_relax(); > > } > > > > + cprman_write(cprman, data->a2w_ctrl_reg, > > + cprman_read(cprman, data->a2w_ctrl_reg) | > > + A2W_PLL_CTRL_PRST_DISABLE); > > + > > return 0; > > } > > I agree with this hunk -- they drop PRST at the very end, after lock. -- Boris Brezillon, Bootlin (formerly Free Electrons) Embedded Linux and Kernel engineering http://bootlin.com

[PATCH v5 3/6] x86/apic: Fix restoring boot irq mode in reboot and kexec/kdump

by Baoquan He

This is a regression fix. Before, to fix erratum AVR31, commit 522e66464467 ("x86/apic: Disable I/O APIC before shutdown of the local APIC") moved lapic_shutdown() calling after disable_IO_APIC() in reboot and kexec/kdump code path. This introdued a regression. The root cause is that disable_IO_APIC() not only clears IO_APIC, also restore boot irq mode by setting LAPIC/APIC/IMCR, calling lapic_shutdown() after disable_IO_APIC() will disable LAPIC and ruin the possible virtual wire mode setting which the code has been trying to do all along. The consequence is, in KVM guest kernel always prints warning as below during kexec/kdump kernel boots up. That happened in setup_local_APIC() since 'do { xxx } while (queued && max_loops > 0)' loop does not function well any more if pending irq exists in APIC IRR after LAPIC is disabled.

[Linux-stable-mirror] [PATCH] megaraid_sas: Do not use 32-bit atomic request descriptor for Ventura controllers

by Shivasharan S

Problem Statement: Sending I/O through 32 bit descriptors to Ventura series of controller results in IO timeout on certain conditions. This error only occurs on systems with high I/O activity on Ventura series controllers. Changes in this patch will prevent driver from using 32 bit descriptor and use 64 bit Descriptors.

[Linux-stable-mirror] [PATCH] drm/i915/breadcrumbs: Ignore unsubmitted signalers

by Chris Wilson

When a request is preempted, it is unsubmitted from the HW queue and removed from the active list of breadcrumbs. In the process, this however triggers the signaler and it may see the clear rbtree with the old, and still valid, seqno, or it may match the cleared seqno with the now zero rq->global_seqno. This confuses the signaler into action and signaling the fence.
