Title
drm/i915/reset: Fix error_state_read ptr + offset use
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/i915/reset: Fix error_state_read ptr + offset use Fix our pointer offset usage in error_state_read when there is no i915_gpu_coredump but buf offset is non-zero. This fixes a kernel page fault can happen when multiple tests are running concurrently in a loop and one is producing engine resets and consuming the i915 error_state dump while the other is forcing full GT resets. (takes a while to trigger). The dmesg call trace: [ 5590.803000] BUG: unable to handle page fault for address: ffffffffa0b0e000 [ 5590.803009] #PF: supervisor read access in kernel mode [ 5590.803013] #PF: error_code(0x0000) - not-present page [ 5590.803016] PGD 5814067 P4D 5814067 PUD 5815063 PMD 109de4067 PTE 0 [ 5590.803022] Oops: 0000 [#1] PREEMPT SMP NOPTI [ 5590.803026] CPU: 5 PID: 13656 Comm: i915_hangman Tainted: G U 5.17.0-rc5-ups69-guc-err-capt-rev6+ #136 [ 5590.803033] Hardware name: Intel Corporation Alder Lake Client Platform/AlderLake-M LP4x RVP, BIOS ADLPFWI1.R00. 3031.A02.2201171222 01/17/2022 [ 5590.803039] RIP: 0010:memcpy_erms+0x6/0x10 [ 5590.803045] Code: fe ff ff cc eb 1e 0f 1f 00 48 89 f8 48 89 d1 48 c1 e9 03 83 e2 07 f3 48 a5 89 d1 f3 a4 c3 66 0f 1f 44 00 00 48 89 f8 48 89 d1 <f3> a4 c3 0f 1f 80 00 00 00 00 48 89 f8 48 83 fa 20 72 7e 40 38 fe [ 5590.803054] RSP: 0018:ffffc90003a8fdf0 EFLAGS: 00010282 [ 5590.803057] RAX: ffff888107ee9000 RBX: ffff888108cb1a00 RCX: 0000000000000f8f [ 5590.803061] RDX: 0000000000001000 RSI: ffffffffa0b0e000 RDI: ffff888107ee9071 [ 5590.803065] RBP: 0000000000000000 R08: 0000000000000001 R09: 0000000000000001 [ 5590.803069] R10: 0000000000000001 R11: 0000000000000002 R12: 0000000000000019 [ 5590.803073] R13: 0000000000174fff R14: 0000000000001000 R15: ffff888107ee9000 [ 5590.803077] FS: 00007f62a99bee80(0000) GS:ffff88849f880000(0000) knlGS:0000000000000000 [ 5590.803082] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 5590.803085] CR2: ffffffffa0b0e000 CR3: 000000010a1a8004 CR4: 0000000000770ee0 [ 5590.803089] PKRU: 55555554 [ 5590.803091] Call Trace: [ 5590.803093] <TASK> [ 5590.803096] error_state_read+0xa1/0xd0 [i915] [ 5590.803175] kernfs_fop_read_iter+0xb2/0x1b0 [ 5590.803180] new_sync_read+0x116/0x1a0 [ 5590.803185] vfs_read+0x114/0x1b0 [ 5590.803189] ksys_read+0x63/0xe0 [ 5590.803193] do_syscall_64+0x38/0xc0 [ 5590.803197] entry_SYSCALL_64_after_hwframe+0x44/0xae [ 5590.803201] RIP: 0033:0x7f62aaea5912 [ 5590.803204] Code: c0 e9 b2 fe ff ff 50 48 8d 3d 5a b9 0c 00 e8 05 19 02 00 0f 1f 44 00 00 f3 0f 1e fa 64 8b 04 25 18 00 00 00 85 c0 75 10 0f 05 <48> 3d 00 f0 ff ff 77 56 c3 0f 1f 44 00 00 48 83 ec 28 48 89 54 24 [ 5590.803213] RSP: 002b:00007fff5b659ae8 EFLAGS: 00000246 ORIG_RAX: 0000000000000000 [ 5590.803218] RAX: ffffffffffffffda RBX: 0000000000100000 RCX: 00007f62aaea5912 [ 5590.803221] RDX: 000000000008b000 RSI: 00007f62a8c4000f RDI: 0000000000000006 [ 5590.803225] RBP: 00007f62a8bcb00f R08: 0000000000200010 R09: 0000000000101000 [ 5590.803229] R10: 0000000000000001 R11: 0000000000000246 R12: 0000000000000006 [ 5590.803233] R13: 0000000000075000 R14: 00007f62a8acb010 R15: 0000000000200000 [ 5590.803238] </TASK> [ 5590.803240] Modules linked in: i915 ttm drm_buddy drm_dp_helper drm_kms_helper syscopyarea sysfillrect sysimgblt fb_sys_fops prime_numbers nfnetlink br_netfilter overlay mei_pxp mei_hdcp x86_pkg_temp_thermal coretemp kvm_intel snd_hda_codec_hdmi snd_hda_intel ---truncated---
