x86/apic: Fix kernel panic when booting with intremap=off and x2apic_phys

2023-06-28T09:12:40+00:00

[ Upstream commit 85d38d5810e285d5aec7fb5283107d1da70c12a9 ] When booting with "intremap=off" and "x2apic_phys" on the kernel command line, the physical x2APIC driver ends up being used even when x2APIC mode is disabled ("intremap=off" disables x2APIC mode). This happens because the first compound condition check in x2apic_phys_probe() is false due to x2apic_mode == 0 and so the following one returns true after default_acpi_madt_oem_check() having already selected the physical x2APIC driver. This results in the following panic: kernel BUG at arch/x86/kernel/apic/io_apic.c:2409! invalid opcode: 0000 [#1] PREEMPT SMP NOPTI CPU: 0 PID: 0 Comm: swapper/0 Not tainted 6.4.0-rc2-ver4.1rc2 #2 Hardware name: Dell Inc.

KVM: arm64: Restore GICv2-on-GICv3 functionality

2023-06-28T09:12:40+00:00

commit 1caa71a7a600f7781ce05ef1e84701c459653663 upstream. When reworking the vgic locking, the vgic distributor registration got simplified, which was a very good cleanup. But just a tad too radical, as we now register the *native* vgic only, ignoring the GICv2-on-GICv3 that allows pre-historic VMs (or so I thought) to run. As it turns out, QEMU still defaults to GICv2 in some cases, and this breaks Nathan's setup! Fix it by propagating the *requested* vgic type rather than the host's version.

arm64: dts: rockchip: fix nEXTRST on SOQuartz

2023-06-28T09:12:34+00:00

[ Upstream commit cf9ae4a0077496e8224d68fc88e3df13dd7e5f37 ] In pre-production prototypes (of which I only know one person having one, Peter Geis), GPIO0 pin A5 was tied to the SDMMC power enable pin on the CM4 connector. On all production models, this is not the case; instead, this pin is used for the nEXTRST signal, and the SDMMC power enable pin is always pulled high. Since everyone currently using the SOQuartz device trees will want this change, it is made to the tree without splitting the trees into two separate ones of which users will then inevitably choose the wrong one. This fixes USB and PCIe on a wide variety of CM4IO-compatible boards which use the nEXTRST signal.

bpf: Fix a bpf_jit_dump issue for x86_64 with sysctl bpf_jit_enable.

2023-06-28T09:12:29+00:00

[ Upstream commit ad96f1c9138e0897bee7f7c5e54b3e24f8b62f57 ] The sysctl net/core/bpf_jit_enable does not work now due to commit 1022a5498f6f ("bpf, x86_64: Use bpf_jit_binary_pack_alloc"). The commit saved the jitted insns into 'rw_image' instead of 'image' which caused bpf_jit_dump not dumping proper content. With 'echo 2 > /proc/sys/net/core/bpf_jit_enable', run './test_progs -t fentry_test'. Without this patch, one of jitted image for one particular prog is: flen=17 proglen=92 pass=4 image=0000000014c64883 from=test_progs pid=1807 00000000: cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc 00000010: cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc 00000020: cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc 00000030: cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc 00000040: cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc 00000050: cc cc cc cc cc cc cc cc cc cc cc cc With this patch, the jitte image for the same prog is: flen=17 proglen=92 pass=4 image=00000000b90254b7 from=test_progs pid=1809 00000000: f3 0f 1e fa 0f 1f 44 00 00 66 90 55 48 89 e5 f3 00000010: 0f 1e fa 31 f6 48 8b 57 00 48 83 fa 07 75 2b 48 00000020: 8b 57 10 83 fa 09 75 22 48 8b 57 08 48 81 e2 ff 00000030: 00 00 00 48 83 fa 08 75 11 48 8b 7f 18 be 01 00 00000040: 00 00 48 83 ff 0a 74 02 31 f6 48 bf 18 d0 14 00 00000050: 00 c9 ff ff 48 89 77 00 31 c0 c9 c3 Fixes: 1022a5498f6f ("bpf, x86_64: Use bpf_jit_binary_pack_alloc") Signed-off-by: Yonghong Song Signed-off-by: Daniel Borkmann Acked-by: Song Liu Link: https://lore.kernel.org/bpf/20230609005439.3173569-1-yhs@fb.com Signed-off-by: Sasha Levin
