But for private ashmem mappings nothing # sets the vma->vm_ops. # # Looking at the problematic patch, it seems to add a requirement that one # call vma_set_anonymous() on a vma, otherwise the dummy_vm_ops will be # used. Using the dummy_vm_ops seem to triggger SIGBUS when traversing # unmapped pages. # # Thus, this patch adds a call to vma_set_anonymous() for ashmem private # mappings and seems to avoid the reported problem. # # Fixes: bfd40eaff5ab ("mm: fix vma_is_anonymous() false-positives") # Cc: Kirill Shutemov <kirill.shutemov@linux.intel.com> # Cc: Andrew Morton <akpm@linux-foundation.org> # Cc: Dmitry Vyukov <dvyukov@google.com> # Cc: Oleg Nesterov <oleg@redhat.com> # Cc: Andrea Arcangeli <aarcange@redhat.com> # Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> # Cc: Hugh Dickins <hughd@google.com> # Cc: Joel Fernandes <joelaf@google.com> # Cc: Colin Cross <ccross@google.com> # Cc: Matthew Wilcox <willy@infradead.org> # Reported-by: Amit Pundir <amit.pundir@linaro.org> # Reported-by: Youling 257 <youling257@gmail.com> # Signed-off-by: John Stultz <john.stultz@linaro.org> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux-gcc --version # < git log --format=%s --max-count=1 44960f2a7b63e224b1091b3e1d6f60e0cdf4be0c # < make -s -j 48 ARCH=nds32 O=/kisskb/build/linus_nds32-allmodconfig_nds32le CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux- allmodconfig # make -s -j 48 ARCH=nds32 O=/kisskb/build/linus_nds32-allmodconfig_nds32le CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux- <stdin>:1335:2: warning: #warning syscall rseq not implemented [-Wcpp] In function 'fill_item_path', inlined from 'configfs_get_target_path' at /kisskb/src/fs/configfs/symlink.c:250:2, inlined from 'configfs_getlink' at /kisskb/src/fs/configfs/symlink.c:272:10, inlined from 'configfs_get_link' at /kisskb/src/fs/configfs/symlink.c:295:10: /kisskb/src/fs/configfs/symlink.c:67:3: warning: 'strncpy' output truncated before terminating nul copying as many bytes from a string as its length [-Wstringop-truncation] strncpy(buffer + length,config_item_name(p),cur);
