----- Original Message ----- > This is the release of crash gcore command, version 1.2.1. > > ChangeLog: > > - Fix failure of coredump at accessing memory for VSYSCALL page due > to wrong conversion of uvtop which wrongly treats address > VSYSCALL_START as belongs to kernel direct mapping region. This fix > executes uvtop in verbose mode to make it always paging and > retrieves the correct physical address from its output. Without > this fix, VSYSCALL page fails to be collected and core dump process > is aborted; though VSYSCALL page is done in the last so allmost all > corefile is already generated. > (d.hatayama@xxxxxxxxxxxxxx) > > - Skip page-faulted pages by lseek() rather than writing zero-filled > pages. By this, generated core file has holes in the corresponding > positions for each page-faulted pages if filesystem supports sparse > files. This is highly useful when the target process has huge > virtual memory space such as qemu process that has huge physical > memory of KVM guest machine. > (d.hatayama@xxxxxxxxxxxxxx) > > - Fix the bug that filter for hugepage shared/private memory can > depend on flags other than HP or HS flags. This was introduced at > the introduction of VM_DONTDUMP where VM_RESERVED flag was > removed. At the time, there was a check to see if VM_REESRVED flag > was set after a check to see if VM_HUGETLB.
