<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> <tt></tt> <tt>- Introduced support for upstream xensource ELF format dumpfiles,</tt> <tt> which will replace the current xendump format in xen 3.0.5. The</tt> <tt> new xen format uses ELF in a non-standard manner such that memory</tt> <tt> contents are defined in section headers instead of the traditional</tt> <tt> manner of using program headers. Testing has been on paravirtualized</tt> <tt> x86, x86 PAE, x86_64 and ia64 dumpfiles. Fully-virtualized dumpfiles</tt> <tt> have not been tested. (anderson@redhat.com)</tt><tt></tt> <tt>- A number of "xencrash" (where the session is run against a xen-syms</tt> <tt> binary) fixes have been applied:</tt> <tt> 1) "bt" did not switch from the ia64 MCA stack to the vcpu stack.</tt> <tt> 2) "bt" caused an infinite loop if ar_bspstore contained an illegal</tt> <tt> value.</tt> <tt> 3) "bt" shows unnecessary unwind warning message. (ia64)</tt> <tt> 4) "man log" caused crash to fail with a segmentation violation.</tt> <tt> 5) "man log" did not have an example.</tt> <tt> (oda@valinux.co.jp)</tt><tt></tt> <tt>- Fix for "vtop" on x86 PAE kernels, which could abort upon reaching</tt> <tt> the PTE translation section, showing the error message: "vtop:</tt> <tt> cannot determine the swap location". (anderson@redhat.com)</tt> <tt> </tt> <tt>- Fix for "vm -p" or "vtop" on 2.6 x86 PAE kernels, which could show</tt> <tt> incorrect swap offsets, because the swap type/offset encoding was</tt> <tt> moved to the high word of the 64-bit PTE. (anderson@redhat.com)</tt><tt></tt> <tt>- Fix for "vm -p" on x86_64 kernels when a PTE referenced a swap</tt> <tt> location, it would show "(not mapped)" instead of the swap location.</tt> <tt> (anderson@redhat.com)</tt><tt></tt> <tt>- In current 2.6 kernels, it is now possible to recognize ppc BOOKE</tt> <tt> processors, which is the current default in crash. If the processor</tt> <tt> is confirmed to not be BOOKE, then page table translation is done</tt> <tt> differently. (antipov@ru.mvista.com)</tt><tt></tt> <tt>- Fix for live system analysis of Ubuntu kernels due to a mismatch</tt> <tt> between /proc/version and the linux_banner string. This was due</tt> <tt> to an appendage to the linux_banner string in Ubuntu kernels.</tt> <tt> (asid@hp.com)</tt><tt></tt> <tt>- Fix for 2.6.21 kernels that fail during initialization with the</tt> <tt> message: "crash: invalid (optional) structure member offsets:</tt> <tt> zone_struct_free_pages or zone_free_pages". This was due to the</tt> <tt> removal of the zone struct's "free_pages" member; instead the</tt> <tt> zone's "vm_stat[NR_FREE_PAGES]" value is used.
