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/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux-gcc --version # < git log --format=%s --max-count=1 2923b27e54242acf27fd16b299e102117c82f52f # < make -s -j 120 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MIPS_CPS_NS16550_BASE=0x1b0003f8 # Added to kconfig CONFIG_MIPS_CPS_NS16550_SHIFT=0 # yes \n \| make -s -j 120 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux- oldconfig yes: standard output: Broken pipe # make -s -j 120 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux- /kisskb/src/drivers/bluetooth/hci_h5.c:920:22: warning: 'rtl_vnd' defined but not used [-Wunused-variable] static struct h5_vnd rtl_vnd = { ^~~~~~~ /kisskb/src/drivers/input/joystick/analog.c:172:2: warning: #warning Precise timer not defined for this architecture.
