Use new return type vm_fault_t for fault handler. For now, this is just documenting that the function returns a VM_FAULT value rather than an errno. Once all instances are converted, vm_fault_t will become a distinct type. Ref-> commit 1c8f4220 ("mm: change return type to vm_fault_t") The aim is to change the return type of finish_fault() and handle_mm_fault() to vm_fault_t type. As part of that clean up return type of all other recursively called functions have been changed to vm_fault_t type. The places from where handle_mm_fault() is getting invoked will be change to vm_fault_t type but in a separate patch. vmf_error() is the newly introduce inline function in 4.17-rc6.

The font files contain bit masks for characters in the cp437 character set, and comments showing what character this is supposed to be. This only makes sense when the terminal used to view the files is set to the same codepage, but all other files in the kernel now use utf-8 encoding. This changes those comments to utf-8 as well, for consistency. Link: http://lkml.kernel.org/r/20180724111600.4158975-3-arnd@arndb.deSigned-off-by:

The ebcdic.c file contains tables for converting between ebcdic and PC codepage 437. I could however not identify which encoding was used for the comments. This seems to be some variation of ISO_8859-1 with non-UTF-8 escape characters. I have converted this to UTF-8 by manually removing the escape characters and then running it through recode, to get the same encoding that we use for the rest of the kernel.

Patch series "memory management documentation updates", v3. Here are several updates to the mm documentation. Aside from really minor changes in the first three patches, the updates are: * move the documentation of kstrdup and friends to "String Manipulation" section * split memory management API into a separate .rst file * adjust formating of the GFP flags description and include it in the reference documentation. This patch (of 7): The description of the strndup_user function misses '*' character at the beginning of the comment to be proper kernel-doc. Add the missing character.

A process can be killed with SIGBUS(BUS_MCEERR_AR) when it tries to allocate a page that was just freed on the way of soft-offline. This is undesirable because soft-offline (which is about corrected error) is less aggressive than hard-offline (which is about uncorrected error), and we can make soft-offline fail and keep using the page for good reason like "system is busy." Two main changes of this patch are: - setting migrate type of the target page to MIGRATE_ISOLATE. As done in free_unref_page_commit(), this makes kernel bypass pcplist when freeing the page. So we can assume that the page is in freelist just after put_page() returns, - setting PG_hwpoison on free page under zone->lock which protects freelists, so this allows us to avoid setting PG_hwpoison on a page that is decided to be allocated soon.

Patch series "mm: soft-offline: fix race against page allocation". Xishi recently reported the issue about race on reusing the target pages of soft offlining. Discussion and analysis showed that we need make sure that setting PG_hwpoison should be done in the right place under zone->lock for soft offline. 1/2 handles free hugepage's case, and 2/2 hanldes free buddy page's case. This patch (of 2): There's a race condition between soft offline and hugetlb_fault which causes unexpected process killing and/or hugetlb allocation failure. The process killing is caused by the following flow: CPU 0 CPU 1 CPU 2 soft offline get_any_page // find the hugetlb is free mmap a hugetlb file page fault ... hugetlb_fault hugetlb_no_page alloc_huge_page // succeed soft_offline_free_page // set hwpoison flag mmap the hugetlb file page fault ... hugetlb_fault hugetlb_no_page find_lock_page return VM_FAULT_HWPOISON mm_fault_error do_sigbus // kill the process The hugetlb allocation failure comes from the following flow: CPU 0 CPU 1 mmap a hugetlb file // reserve all free page but don't fault-in soft offline get_any_page // find the hugetlb is free soft_offline_free_page // set hwpoison flag dissolve_free_huge_page // fail because all free hugepages are reserved page fault ... hugetlb_fault hugetlb_no_page alloc_huge_page ... dequeue_huge_page_node_exact // ignore hwpoisoned hugepage // and finally fail due to no-mem The root cause of this is that current soft-offline code is written based on an assumption that PageHWPoison flag should be set at first to avoid accessing the corrupted data. This makes sense for memory_failure() or hard offline, but does not for soft offline because soft offline is about corrected (not uncorrected) error and is safe from data lost. This patch changes soft offline semantics where it sets PageHWPoison flag only after containment of the error page completes successfully.

Disallows open of FIFOs or regular files not owned by the user in world writable sticky directories, unless the owner is the same as that of the directory or the file is opened without the O_CREAT flag. The purpose is to make data spoofing attacks harder. This protection can be turned on and off separately for FIFOs and regular files via sysctl, just like the symlinks/hardlinks protection. This patch is based on Openwall's "HARDEN_FIFO" feature by Solar Designer. This is a brief list of old vulnerabilities that could have been prevented by this feature, some of them even allow for privilege escalation: CVE-2000-1134 CVE-2007-3852 CVE-2008-0525 CVE-2009-0416 CVE-2011-4834 CVE-2015-1838 CVE-2015-7442 CVE-2016-7489 This list is not meant to be complete. It's difficult to track down all vulnerabilities of this kind because they were often reported without any mention of this particular attack vector. In fact, before hardlinks/symlinks restrictions, fifos/regular files weren't the favorite vehicle to exploit them.

An HFS+ filesystem can be mounted read-only without having a metadata directory, which is needed to support hardlinks. But if the catalog data is corrupted, a directory lookup may still find dentries claiming to be hardlinks. hfsplus_lookup() does check that ->hidden_dir is not NULL in such a situation, but mistakenly does so after dereferencing it for the first time. Reorder this check to prevent a crash. This happens when looking up corrupted catalog data (dentry) on a filesystem with no metadata directory (this could only ever happen on a read-only mount).

Merge fixes for missing TLB shootdowns. This fixes a couple of cases that involved us possibly freeing page table structures before the required TLB shootdown had been done. There are a few cleanup patches to make the code easier to follow, and to avoid some of the more problematic cases entirely when not necessary. To make this easier for backports, it undoes the recent lazy TLB patches, because the cleanups and fixes are more important, and Rik is ok with re-doing them later when things have calmed down. The missing TLB flush was only delayed, and the wrong ordering only happened under memory pressure (and in theory under a couple of other fairly theoretical situations), so this may have been all very unlikely to have hit people in practice. But getting the TLB shootdown wrong is _so_ hard to debug and see that I consider this a crticial fix. Many thanks to Jann Horn for having debugged this. * tlb-fixes: x86/mm: Only use tlb_remove_table() for paravirt mm: mmu_notifier fix for tlb_end_vma mm/tlb, x86/mm: Support invalidating TLB caches for RCU_TABLE_FREE mm/tlb: Remove tlb_remove_table() non-concurrent condition mm: move tlb_table_flush to tlb_flush_mmu_free x86/mm/tlb: Revert the recent lazy TLB patches

Pull MIPS fixes from Paul Burton: - Fix microMIPS build failures by adding a .insn directive to the barrier_before_unreachable() asm statement in order to convince the toolchain that the asm statement is a valid branch target rather than a bogus attempt to switch ISA. - Clean up our declarations of TLB functions that we overwrite with generated code in order to prevent the compiler making assumptions about alignment that cause microMIPS kernels built with GCC 7 & above to die early during boot. - Fix up a regression for MIPS32 kernels which slipped into the main MIPS pull for 4.19, causing CONFIG_32BIT=y kernels to contain inappropriate MIPS64 instructions. - Extend our existing workaround for MIPSr6 builds that end up using the __multi3 intrinsic to GCC 7 & below, rather than just GCC 7. * tag 'mips_4.19_2' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: MIPS: lib: Provide MIPS64r6 __multi3() for GCC < 7 MIPS: Workaround GCC __builtin_unreachable reordering bug compiler.h: Allow arch-specific asm/compiler.h MIPS: Avoid move psuedo-instruction whilst using MIPS_ISA_LEVEL MIPS: Consistently declare TLB functions MIPS: Export tlbmiss_handler_setup_pgd near its definition -
