Download from: http://people.redhat.com/anderson or https://github.com/crash-utility/crash/releases Note that the new GitHub repository was initiated with crash-7.0.4. The master branch will contain all patches that are queued for the next release: $ git clone git://github.com/crash-utility/crash.git Changelog: - Fix for the "runq -g" option for kernels that are configured with CONFIG_FAIR_GROUP_SCHED, but not CONFIG_CFS_BANDWIDTH. Without the patch, the command fails with the message "runq: invalid structure member offset: cfs_rq_throttled". (vinayakm.list@xxxxxxxxx) - Add support for Xen PVH guest types introduced in Xen 4.4. Without the patch, running against a Xen 4.4 hypervisor binary would fail during session initialization with the error message "crash: invalid structure member offset: domain_is_hvm". In addition, the PVH guest type is being registered internally as an HVM guest type, the debug "help -X ofs" command's display of the domain_domain_flags offset has been fixed to show it in decimal, and the setting of the internal dc->domain_flags has been fixed to contain all flags set, not just the first one found. (dslutz@xxxxxxxxxxx) - Fix for the "kmem -S" command on Linux 3.1 and later kernels that are configured with CONFIG_SLUB. Because the the page structure's inuse and objects fields used by SLUB were changed from discrete u16 types to bit-fields within an unsigned int, the display of per-node partial slab statistics are incorrect. Without the patch, the TOTAL and ALLOCATED values are incorrectly shown as equal values, and therefore the FREE value is always zero. (anderson@xxxxxxxxxx) - Fix for the "kmem -S" command for kernels that are configured with CONFIG_SLUB. Eash per-cpu slab object dump may show incorrect ALLOCATED and FREE values; and as seen on Linux 3.5 and later kernels, the TOTAL value and the number of individual objects dumped may also be incorrect (too small). (anderson@xxxxxxxxxx) - When executing the commands from an input file specified by the "-i <file>" command line option, or when accepting input from a file as a set of commands or as a set of command arguments using the "<" redirection character, unconditionally cease the operation if CTRL-c is entered. Without the patch, depending upon the command that was running when the SIGINT was received, the operation may continue uninterruptibly until the file contents are consumed. (anderson@xxxxxxxxxx) - Enhanced the "bt -F" option such that if "-F" is entered twice, and if the stack frame contents reference a slab cache object, both the slab cache name and the stack contents will be displayed within brackets. (anderson@xxxxxxxxxx) - Enhanced the "rd -S" option such that if "-S" is entered twice, and if the memory contents reference a slab cache object, both the slab cache name and the memory contents will be displayed within brackets. (anderson@xxxxxxxxxx) - Fix for the X86_64 "bt" command to prevent an unwarranted message indicating "WARNING: possibly bogus exception frame" generated from a blocked kernel thread that was in the process of exec'ing a user process via the call_usermodehelper() facility. (anderson@xxxxxxxxxx) - Fix for the X86_64 "bt" command to more correctly determine the function frame that called into an interrupted function. Without the patch, the first frame just above an IRQ exception frame register dump may show an invalid/stale function. (anderson@xxxxxxxxxx) - Fix for the X86_64 "bt" command if a page fault exception was generated by the invalid contents of the RIP register. Without the patch, the exception frame register dump is not displayed above the "page_fault" stack frame; and in a related issue, the "bt -e" option will not find and display the exception frame. (anderson@xxxxxxxxxx) - When invoking a crash session with a compressed vmlinux file, make the same host-machine/vmlinux endian verification that is done with uncompressed vmlinx files. (anderson@xxxxxxxxxx) - Reduce the number of CTRL-c entries required to unconditionally terminate any manually-entered command from three to one. (anderson@xxxxxxxxxx) - Fix for the X86_64 "bt" command if an async page fault exception occurred in a KVM guest running a Linux 2.6.38 or later kernel. Without the patch, the exception frame register dump is not displayed above the "async_page_fault" stack frame.
