0.2.7-RC2 release

Hello all,

The 0.2.7-RC2 release is available. It is mainly a bug-fix/optimization release, without new features.

Bug fixes:

  • MIPS JIT: fixed a problem of jump in delay slots (occuring with a “forward” jump). This caused a malfunction for C7200-IO-2FE and C7200-IO-GE-E cards.
  • Cisco 2600: fixed a bug in DMA handling which caused incorrect writes out of DPRAM memory (and lead to image crashes).
  • Fixed JIT instruction tables, which caused a higher startup delay of the emulator on AMD64 platforms.
  • Serial interfaces (NM-4T, PA-4T, PA-8T): now allows MTU up to 18000 bytes.
  • NM-16ESW: filter CDP specifically to not propagate frames to all ports.
  • NM-4E: now works correctly on Cisco 2600 platforms.
  • Fixed source build (in NetIO filters) when PCAP is lacking.
  • Fixed source build for non-JIT platforms.

Optimizations:

  • Network interrupt handling was rewritten. Now these IRQs are managed on a per-slot/port basis, this also leads to a more accurate network device emulation.
  • PowerPC: optimizations in Condition Register (CR) handling.
  • JIT (MIPS, PowerPC): optimizations in jumps between different pages, allowing an higher performance. However, it may require to recompute idle-pc values. Greg will provide an “oldidle” compatibility option in Dynagen 0.9.1 for people who don’t want to change these values now.
  • JIT (MIPS, PowerPC): added a cache for instruction tables (as disk files), allowing a faster startup. If these files are deleted, they are rebuilt dynamically.

    I would like to ask you if a Dynagen upgrade is necessary for this new version.

    Dynagen 0.9.1 has been released. This is a bugfix release with no new features. However this version performs much more rigorous validity checking of the network file and of the adapters and modules used with the different router modules. And rather than silently ignoring unknown configuration options in network files, dynagen now throws a warning in most cases. These additional validations should help with troubleshooting hard to spot syntax errors in your net files.

    As Chris said, dynamips 0.2.7 RC2 adds an enhancement to the VM to allow direct jumps between JIT blocks. But in doing so an idlepc value calculated pre RC2 might not be seen anymore. So previously determined Idle PC values may be incompatible and need to be recalculated. However Chris added an option to disable this functionality so you can continue to use your old values until you get a chance to check them all. Use “oldidle = true” in your lab to set this option (at either the top level of the network file or in the router / router defaults section). Just remember to remove this option or set it to false before calculating any new values.

    The Dynagen idlepc database is stored in dynagenidledb.ini in your home directory by default, unless you changed it in your dynagen.ini. You can either delete the file to start over from scratch, or remove entries line by line with any text editor.

    Also, the tutorial has been updated with a walkthrough of using ghostios and sparsemem, and using the packet capture feature with Wireshark.

    For the detailed changelog, see here: http://dynagen.org/page6/changelog.html

    Had also the problem with the c7200-adventerpricek9-sna-mz.124-6.T6.bin
    after reading this topic. I decompress it and worked OK.

    The c7200-ik9s-mz.123-10.bin ( one the I use becouse of testing our network) works fine compressed. But is a bit smaller :)

    Tried some options but did not made any change to the problem.

    I’m very happy with Dynamips and use it a lot :) Good work.

    Hi,

    I observed, that version 0.2.7-rc2 doesn’t like compressed ios images. Testing all platforms only 3620 be able to correctly run the compressed ios. The previous version 0.2.7-rc1 on all platforms (beyond 2600) correctly run compressed ios image.

    Hi,

    Not Working mean - working with bugs - looping.

    Hi, I have a strange problem and didn’t found any solution. I’m running about 12 routers and dynamips has problem with opening files.

    memzone_open_file: open: Too many open files
    dev_create_ghost_ram: mmap: Too many open files
    RAM_ghost: unable to create device.
    C3600 instance ‘BB3′ (id 12):
    VM Status : 0
    RAM size : 128 Mb
    NVRAM size : 128 Kb
    Chassis : 3640
    IOS image : c3640-jk9o3s-mz.124-13a.image
    load_elf_image: open: Too many open files
    C3600 ‘BB3′: failed to load Cisco IOS image ‘c3640-jk9o3s-mz.124-13a.image’.

    Is this a dynamips, OS (win xp) or cygwin problem? I’m using cygwin from cygwin.com and dynamips compiled from source. Thanks for any advise.

    Roman> Can you possibly email me your .net file (paquette_mark_at_hotmail.com, where the _at_ is to be replaced by @ symbol), or batch file, whichever you’re using and I’ll download the IOS myself and see if I suffer a similar issue. For me, and this may be unrelated, on a multi-dual-core-processor server, run dynamips (under DynaGen control) in a seperate instance per 4 routers (as I’ve found this to work well) … and I use IceAffinity to launch each with a seperate processor affinity (leaving processor 0 free for system work).
    I don’t know of any file-open limitation you would encounter running DynaMIPS … I can’t imagine any of us even hitting a file-open OS limitation although for sure we could run out of memory (inc. swap space) by mass-opening every document on our HDs.
    Lastly … I have not bothered running the latest DynaMIPS because of the comments I’ve read (and the prior version is working for me), so I can’t say if it’s a ‘new’ DynaMIPS issue … have you tried going back to RC1?

    Mark, thank for help, but I solved it by using dynamips with Linux. What is interesting, overall performance is much better then under win. So I’m happy now, this problem forced me to install Linux:)
