The recovery code has specific enabling for several # possible page states and needs new enabling to handle poison in dax # mappings. # # In order to support reliable reverse mapping of user space addresses: # # 1/ Add new locking in the memory_failure() rmap path to prevent races # that would typically be handled by the page lock. # # 2/ Since dev_pagemap pages are hidden from the page allocator and the # "compound page" accounting machinery, add a mechanism to determine # the size of the mapping that encompasses a given poisoned pfn. # # 3/ Given pmem errors can be repaired, change the speculatively # accessed poison protection, mce_unmap_kpfn(), to be reversible and # otherwise allow ongoing access from the kernel. # # A side effect of this enabling is that MADV_HWPOISON becomes usable # for dax mappings, however the primary motivation is to allow the # system to survive userspace consumption of hardware-poison via dax. # Specifically the current behavior is: # # mce: Uncorrected hardware memory error in user-access at af34214200 # {1}[Hardware Error]: It has been corrected by h/w and requires no further action # mce: [Hardware Error]: Machine check events logged # {1}[Hardware Error]: event severity: corrected # Memory failure: 0xaf34214: reserved kernel page still referenced by 1 users # [..] # Memory failure: 0xaf34214: recovery action for reserved kernel page: Failed # mce: Memory error not recovered # <reboot> # # ...and with these changes: # # Injecting memory failure for pfn 0x20cb00 at process virtual address 0x7f763dd00000 # Memory failure: 0x20cb00: Killing dax-pmd:5421 due to hardware memory corruption # Memory failure: 0x20cb00: recovery action for dax page: Recovered # # Given all the cross dependencies I propose taking this through # nvdimm.git with acks from Naoya, x86/core, x86/RAS, and of course dax # folks" # # * tag 'libnvdimm-for-4.19_dax-memory-failure' of gitolite.kernel.org:pub/scm/linux/kernel/git/nvdimm/nvdimm: # libnvdimm, pmem: Restore page attributes when clearing errors # x86/memory_failure: Introduce {set, clear}_mce_nospec() # x86/mm/pat: Prepare {reserve, free}_memtype() for "decoy" addresses # mm, memory_failure: Teach memory_failure() about dev_pagemap pages # filesystem-dax: Introduce dax_lock_mapping_entry() # mm, memory_failure: Collect mapping size in collect_procs() # mm, madvise_inject_error: Let memory_failure() optionally take a page reference # mm, dev_pagemap: Do not clear ->mapping on final put # mm, madvise_inject_error: Disable MADV_SOFT_OFFLINE for ZONE_DEVICE pages # filesystem-dax: Set page->index # device-dax: Set page->index # device-dax: Enable page_mapping() # device-dax: Convert to vmf_insert_mixed and vm_fault_t # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-gcc --version # < git log --format=%s --max-count=1 2923b27e54242acf27fd16b299e102117c82f52f # < make -s -j 120 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_HAVE_FTRACE_MCOUNT_RECORD=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MODULE_SIG=n # yes \n | make -s -j 120 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 120 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- <stdin>:1332:2: warning: #warning syscall io_pgetevents not implemented [-Wcpp] <stdin>:1335:2: warning: #warning syscall rseq not implemented [-Wcpp] /kisskb/src/drivers/bluetooth/hci_h5.c:920:22: warning: 'rtl_vnd' defined but not used [-Wunused-variable] static struct h5_vnd rtl_vnd = { ^ In file included from /kisskb/src/arch/sparc/include/asm/cmpxchg.h:5:0, from /kisskb/src/arch/sparc/include/asm/atomic_64.h:12, from /kisskb/src/arch/sparc/include/asm/atomic.h:5, from /kisskb/src/include/linux/atomic.h:7, from /kisskb/src/include/asm-generic/bitops/lock.h:5, from /kisskb/src/arch/sparc/include/asm/bitops_64.h:52, from /kisskb/src/arch/sparc/include/asm/bitops.h:5, from /kisskb/src/include/linux/bitops.h:19, from /kisskb/src/include/linux/kernel.h:11, from /kisskb/src/include/linux/list.h:9, from /kisskb/src/include/linux/wait.h:7, from /kisskb/src/include/linux/wait_bit.h:8, from /kisskb/src/include/linux/fs.h:6, from /kisskb/src/fs/ocfs2/file.c:27: /kisskb/src/fs/ocfs2/file.c: In function 'ocfs2_file_write_iter': /kisskb/src/arch/sparc/include/asm/cmpxchg_64.h:55:22: warning: value computed is not used [-Wunused-value] #define xchg(ptr,x) ((__typeof__(*(ptr)))__xchg((unsigned long)(x),(ptr),sizeof(*(ptr)))) ^ /kisskb/src/fs/ocfs2/file.c:2386:3: note: in expansion of macro 'xchg' xchg(&iocb->ki_complete, saved_ki_complete);
