[PATCH v2] KVM: x86: accept userspace interrupt only if no event is injected

by Paolo Bonzini

Once an exception has been injected, any side effects related to the exception (such as setting CR2 or DR6) have been taked place. Therefore, once KVM sets the VM-entry interruption information field or the AMD EVENTINJ field, the next VM-entry must deliver that exception. Pending interrupts are processed after injected exceptions, so in theory it would not be a problem to use KVM_INTERRUPT when an injected exception is present. However, DOSEMU is using run->ready_for_interrupt_injection to detect interrupt windows and then using KVM_SET_SREGS/KVM_SET_REGS to inject the interrupt manually. For this to work, the interrupt window must be delayed after the completion of the previous event injection.

[PATCH] alpha: register early reserved memory in memblock

by Mike Rapoport

From: Mike Rapoport <rppt(a)linux.ibm.com> The memory reserved by console/PALcode or non-volatile memory is not added to memblock.memory. Since commit fa3354e4ea39 (mm: free_area_init: use maximal zone PFNs rather than zone sizes) the initialization of the memory map relies on the accuracy of memblock.memory to properly calculate zone sizes. The holes in memblock.memory caused by absent regions reserved by the firmware cause incorrect initialization of struct pages which leads to BUG() during the initial page freeing: BUG: Bad page state in process swapper pfn:2ffc53 page:fffffc000ecf14c0 refcount:0 mapcount:1 mapping:0000000000000000 index:0x0 flags: 0x0() raw: 0000000000000000 0000000000000000 0000000000000000 0000000000000000 raw: 0000000000000000 0000000000000000 0000000000000000 0000000000000000 page dumped because: nonzero mapcount Modules linked in: CPU: 0 PID: 0 Comm: swapper Not tainted 5.7.0-03841-gfa3354e4ea39-dirty #26 fffffc0001b5bd68 fffffc0001b5be80 fffffc00011cd148 fffffc000ecf14c0 fffffc00019803df fffffc0001b5be80 fffffc00011ce340 fffffc000ecf14c0 0000000000000000 fffffc0001b5be80 fffffc0001b482c0 fffffc00027d6618 fffffc00027da7d0 00000000002ff97a 0000000000000000 fffffc0001b5be80 fffffc00011d1abc fffffc000ecf14c0 fffffc0002d00000 fffffc0001b5be80 fffffc0001b2350c 0000000000300000 fffffc0001b48298 fffffc0001b482c0 Trace: [<fffffc00011cd148>] bad_page+0x168/0x1b0 [<fffffc00011ce340>] free_pcp_prepare+0x1e0/0x290 [<fffffc00011d1abc>] free_unref_page+0x2c/0xa0 [<fffffc00014ee5f0>] cmp_ex_sort+0x0/0x30 [<fffffc00014ee5f0>] cmp_ex_sort+0x0/0x30 [<fffffc000101001c>] _stext+0x1c/0x20 Fix this by registering the reserved ranges in memblock.memory.

[merged] hugetlbfs-fix-mount-mode-command-line-processing.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: hugetlbfs: fix mount mode command line processing has been removed from the -mm tree. Its filename was hugetlbfs-fix-mount-mode-command-line-processing.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Mike Kravetz <mike.kravetz(a)oracle.com> Subject: hugetlbfs: fix mount mode command line processing In commit 32021982a324 ("hugetlbfs: Convert to fs_context") processing of the mount mode string was changed from match_octal() to fsparam_u32. This changed existing behavior as match_octal does not require octal values to have a '0' prefix, but fsparam_u32 does. Use fsparam_u32oct which provides the same behavior as match_octal.

[merged] memblock-make-for_each_mem_range-traverse-memblock_hotplug-regions.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: memblock: make for_each_mem_range() traverse MEMBLOCK_HOTPLUG regions has been removed from the -mm tree. Its filename was memblock-make-for_each_mem_range-traverse-memblock_hotplug-regions.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Mike Rapoport <rppt(a)linux.ibm.com> Subject: memblock: make for_each_mem_range() traverse MEMBLOCK_HOTPLUG regions Commit b10d6bca8720 ("arch, drivers: replace for_each_membock() with for_each_mem_range()") didn't take into account that when there is movable_node parameter in the kernel command line, for_each_mem_range() would skip ranges marked with MEMBLOCK_HOTPLUG. The page table setup code in POWER uses for_each_mem_range() to create the linear mapping of the physical memory and since the regions marked as MEMORY_HOTPLUG are skipped, they never make it to the linear map. A later access to the memory in those ranges will fail: [ 2.271743] BUG: Unable to handle kernel data access on write at 0xc000000400000000 [ 2.271984] Faulting instruction address: 0xc00000000008a3c0 [ 2.272568] Oops: Kernel access of bad area, sig: 11 [#1] [ 2.272683] LE PAGE_SIZE=64K MMU=Radix SMP NR_CPUS=2048 NUMA pSeries [ 2.273063] Modules linked in: [ 2.273435] CPU: 0 PID: 53 Comm: kworker/u2:0 Not tainted 5.13.0 #7 [ 2.273832] NIP: c00000000008a3c0 LR: c0000000003c1ed8 CTR: 0000000000000040 [ 2.273918] REGS: c000000008a57770 TRAP: 0300 Not tainted (5.13.0) [ 2.274036] MSR: 8000000002009033 <SF,VEC,EE,ME,IR,DR,RI,LE> CR: 84222202 XER: 20040000 [ 2.274454] CFAR: c0000000003c1ed4 DAR: c000000400000000 DSISR: 42000000 IRQMASK: 0 [ 2.274454] GPR00: c0000000003c1ed8 c000000008a57a10 c0000000019da700 c000000400000000 [ 2.274454] GPR04: 0000000000000280 0000000000000180 0000000000000400 0000000000000200 [ 2.274454] GPR08: 0000000000000100 0000000000000080 0000000000000040 0000000000000300 [ 2.274454] GPR12: 0000000000000380 c000000001bc0000 c0000000001660c8 c000000006337e00 [ 2.274454] GPR16: 0000000000000000 0000000000000000 0000000000000000 0000000000000000 [ 2.274454] GPR20: 0000000040000000 0000000020000000 c000000001a81990 c000000008c30000 [ 2.274454] GPR24: c000000008c20000 c000000001a81998 000fffffffff0000 c000000001a819a0 [ 2.274454] GPR28: c000000001a81908 c00c000001000000 c000000008c40000 c000000008a64680 [ 2.275520] NIP [c00000000008a3c0] clear_user_page+0x50/0x80 [ 2.276333] LR [c0000000003c1ed8] __handle_mm_fault+0xc88/0x1910 [ 2.276688] Call Trace: [ 2.276839] [c000000008a57a10] [c0000000003c1e94] __handle_mm_fault+0xc44/0x1910 (unreliable) [ 2.277142] [c000000008a57af0] [c0000000003c2c90] handle_mm_fault+0x130/0x2a0 [ 2.277331] [c000000008a57b40] [c0000000003b5f08] __get_user_pages+0x248/0x610 [ 2.277541] [c000000008a57c40] [c0000000003b848c] __get_user_pages_remote+0x12c/0x3e0 [ 2.277768] [c000000008a57cd0] [c000000000473f24] get_arg_page+0x54/0xf0 [ 2.277959] [c000000008a57d10] [c000000000474a7c] copy_string_kernel+0x11c/0x210 [ 2.278159] [c000000008a57d80] [c00000000047663c] kernel_execve+0x16c/0x220 [ 2.278361] [c000000008a57dd0] [c000000000166270] call_usermodehelper_exec_async+0x1b0/0x2f0 [ 2.278543] [c000000008a57e10] [c00000000000d5ec] ret_from_kernel_thread+0x5c/0x70 [ 2.278870] Instruction dump: [ 2.279214] 79280fa4 79271764 79261f24 794ae8e2 7ca94214 7d683a14 7c893a14 7d893050 [ 2.279416] 7d4903a6 60000000 60000000 60000000 <7c001fec> 7c091fec 7c081fec 7c051fec [ 2.280193] ---[ end trace 490b8c67e6075e09 ]--- Making for_each_mem_range() include MEMBLOCK_HOTPLUG regions in the traversal fixes this issue.
