[PATCH 1/2] x86/mpparse: avoid overwriting boot_cpu_physical_apicid

by Kevin Mitchell

When booting with ACPI unavailable or disabled, get_smp_config() ends up calling MP_processor_info() for each CPU found in the MPS table. Previously, this resulted in boot_cpu_physical_apicid getting unconditionally overwritten by the apicid of whatever processor had the CPU_BOOTPROCESSOR flag. This occurred even if boot_cpu_physical_apicid had already been more reliably determined in register_lapic_address() by calling read_apic_id() from the actual boot processor. Ordinariliy, this is not a problem because the boot processor really is the one with the CPU_BOOTPROCESSOR flag. However, kexec is an exception in which the kernel may be booted from any processor regardless of the MPS table contents. In this case, boot_cpu_physical_apicid may not indicate the actual boot processor. This was particularly problematic when the second kernel was booted with NR_CPUS fewer than the number of physical processors. It's the job of generic_processor_info() to decide which CPUs to bring up in this case. That obviously must include the real boot processor which it takes care to save a slot for. It relies upon the contents of boot_cpu_physical_apicid to do this, which if incorrect, may result in the boot processor getting left out. This condition can be discovered by smp_sanity_check() and rectified by adding the boot processor to the phys_cpu_present_map with the warning "weird, boot CPU (#%d) not listed by the BIOS". However, commit 3e730dad3b6da ("x86/apic: Unify interrupt mode setup for SMP-capable system") caused setup_local_APIC() to be called before this could happen resulting in a BUG_ON(!apic->apic_id_registered()): [ 0.655452] ------------[ cut here ]------------ [ 0.660610] Kernel BUG at setup_local_APIC+0x74/0x280 [verbose debug info unavailable] [ 0.669466] invalid opcode: 0000 [#1] SMP [ 0.673948] CPU: 0 PID: 0 Comm: swapper/0 Not tainted 4.19.109.Ar-16509018.eostrunkkernel419 #1 [ 0.683670] Hardware name: Quanta Quanta LY6 (1LY6UZZ0FBC), BIOS 1.0.6.0-e7d6a55 11/26/2015 [ 0.693007] RIP: 0010:setup_local_APIC+0x74/0x280 [ 0.698264] Code: 80 e4 fe bf f0 00 00 00 89 c6 48 8b 05 0f 1a 8e 00 ff 50 10 e8 12 53 fd ff 48 8b 05 00 1a 8e 00 ff 90 a0 00 00 00 85 c0 75 02 <0f> 0b 48 8b 05 ed 19 8e 00 41 be 00 02 00 00 ff 90 b0 00 00 00 48 [ 0.719251] RSP: 0000:ffffffff81a03e20 EFLAGS: 00010246 [ 0.725091] RAX: 0000000000000000 RBX: 0000000000000003 RCX: 0000000000000000 [ 0.733066] RDX: 0000000000000000 RSI: 000000000000000f RDI: 0000000000000020 [ 0.741041] RBP: ffffffff81a03e98 R08: 0000000000000002 R09: 0000000000000000 [ 0.749014] R10: ffffffff81a204e0 R11: ffffffff81b50ea7 R12: 0000000000000000 [ 0.756989] R13: ffffffff81aef920 R14: ffffffff81af60a0 R15: 0000000000000000 [ 0.764965] FS: 0000000000000000(0000) GS:ffff888036800000(0000) knlGS:0000000000000000 [ 0.774007] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 0.780427] CR2: ffff888035c01000 CR3: 0000000035a08000 CR4: 00000000000006b0 [ 0.788401] Call Trace: [ 0.791137] ? amd_iommu_prepare+0x15/0x2a [ 0.795717] apic_bsp_setup+0x55/0x75 [ 0.799808] apic_intr_mode_init+0x169/0x16e [ 0.804579] x86_late_time_init+0x10/0x17 [ 0.809062] start_kernel+0x37e/0x3fe [ 0.813154] x86_64_start_reservations+0x2a/0x2c [ 0.818316] x86_64_start_kernel+0x72/0x75 [ 0.822886] secondary_startup_64+0xa4/0xb0 [ 0.827564] ---[ end trace 237b64da0fd9b22e ]--- This change avoids these issues by only setting boot_cpu_physical_apicid from the MPS table if it is not already set, which can occur in the construct_default_ISA_mptable() path. Otherwise, boot_cpu_physical_apicid will already have been set in register_lapic_address() and should therefore remain untouched. Looking through all the places where boot_cpu_physical_apicid is accessed, nearly all of them assume that boot_cpu_physical_apicid should match read_apic_id() on the booting processor. The only place that might intend to use the BSP apicid listed in the MPS table is amd_numa_init(), which explicitly requires boot_cpu_physical_apicid to be the lowest apicid of all processors. Ironically, due to the early exit short circuit in early_get_smp_config(), it instead gets boot_cpu_physical_apicid = read_apic_id() rather than the MPS table BSP. The behaviour of amd_numa_init() is therefore unaffected by this change.

[PATCH v2 07/17] irqchip/gic: Atomically update affinity

by Marc Zyngier

The GIC driver uses a RMW sequence to update the affinity, and relies on the gic_lock_irqsave/gic_unlock_irqrestore sequences to update it atomically. But these sequences only expend into anything meaningful if the BL_SWITCHER option is selected, which almost never happens. It also turns out that using a RMW and locks is just as silly, as the GIC distributor supports byte accesses for the GICD_TARGETRn registers, which when used make the update atomic by definition. Drop the terminally broken code and replace it by a byte write.

[PATCH 1/2] KVM: SVM: avoid infinite loop on NPF from bad address

by Paolo Bonzini

When a nested page fault is taken from an address that does not have a memslot associated to it, kvm_mmu_do_page_fault returns RET_PF_EMULATE (via mmu_set_spte) and kvm_mmu_page_fault then invokes svm_need_emulation_on_page_fault. The default answer there is to return false, but in this case this just causes the page fault to be retried ad libitum. Since this is not a fast path, and the only other case where it is taken is an erratum, just stick a kvm_vcpu_gfn_to_memslot check in there to detect the common case where the erratum is not happening. This fixes an infinite loop in the new set_memory_region_test.

However, extended inode is now 64-byte form, which can across page boundary in principle if the location is specified on purpose, although it's hard to be generated by mkfs due to the allocation policy and rarely used by Android use case now mainly for > 4GiB files. For now, only two fields `i_ctime_nsec` and `i_nlink' couldn't be read from disk properly and cause out-of-bound memory read with random value. Let's fix now.

[PATCH] drm/rockchip: Require the YTR modifier for AFBC

by Alyssa Rosenzweig

The AFBC decoder used in the Rockchip VOP assumes the use of the YUV-like colourspace transform (YTR). YTR is lossless for RGB(A) buffers, which covers the RGBA8 and RGB565 formats supported in vop_convert_afbc_format. Use of YTR is signaled with the AFBC_FORMAT_MOD_YTR modifier, which prior to this commit was missing. As such, a producer would have to generate buffers that do not use YTR, which the VOP would erroneously decode as YTR, leading to severe visual corruption. The upstream AFBC support was developed against a captured frame, which failed to exercise modifier support. Prior to bring-up of AFBC in Mesa (in the Panfrost driver), no open userspace respected modifier reporting. As such, this change is not expected to affect broken userspaces. Tested on RK3399 with Panfrost and Weston.
