523: - Bug: CDP not working with serial interfaces ("debug cdp events" reports
524: a checksum problem).
525:
526: 07-Feb-2006
527: -----------
528: - Started the 0.2.4 release.
529: - Modified the command line parser to allow many NIO per PA (for example
530: for serials).
531: - A lot of code cleanups in the C7200 initialization.
532: - Added PA-8T support.
533: - To fix: CDP with Serial interfaces: using cp_len (instead of cp_len+4)
534: in packet rx fixes the problem but breaks IP. Probably something related
535: to padding, see how a CDP packet is sent (special flag in tx ring ?)
536: - Added virtual "beqz" instruction.
537: - Added the "-X" option, allowing to use host memory directly instead of
538: mapping a file to simulate RAM (faster).
539: - Beginning of code reorganization to allow multiple instance contexts.
540:
541: 08-Feb-2006
542: -----------
543: - Added a basic virtual Frame-Relay switch. Unfortunately, LMI must be
544: implemented to maintain links up.
545: - Finally found the problem related to CDP! It was simply a padding problem.
546:
547: 09-Feb-2006
548: -----------
549: - Add support of promiscuous mode for the DEC21140 "unicast limiter":

552: a "length substractor" for the txring.
553:
554: 10-Feb-2006
555: -----------
556: - Played a little with the PA-POS-OC3, without success.
557:
558: 14-Feb-2006
559: -----------

562: - Integrated a Makefile patch from Max Khon for FreeBSD.
563: - Updated documentation.
564: - Release 0.2.4.
1.1.1.4 root 565:
566: 15-Feb-2006
567: -----------
568: - Fixed a cosmetic bug when displaying MAC address at startup.
569: - Fixed a stupid bug in "srav" instruction in x86_64 JIT code. The
570: arithmetic shift operation was done on a 64-bit basic instead of 32-bit,
571: causing bad propagation of the sign-bit.
572: - Added support for multiple instances (no CLI present yet).
573:
574: 17-Feb-2006
575: -----------
576: - Fixed 2 bugs in Frame-Relay switch: a crash occured when receiving
577: a packet gave an error, and if many DLCI with the same ID on different
578: interfaces were used, only one was announced on one interface.
579:
580: 18-Feb-2006
581: -----------
582: - Began work on advanced configuration parsing (instances).
583:

602:
603: 02-Mar-2006
604: -----------

1055: to bind console and AUX ports to real serial ports. Many thanks to him.
1056:
1057: 20-Jun-2006
1058: -----------
1059: - Playing with the PCMCIA stuff (especially CIS)
1060:
1061: 21-Jun-2006

1078: - Modified the NIO RX handling (packet receiving is done in NIO module).
1079:
1080: 27-Jun-2006
1081: -----------
1082: - bugfix: PA-4E/PA-8E not working with IOS 12.0T (incorrect device length).
1083: (BTS entry #17).

1111: this number reaches a threshold (512 pages seems to be a good value).
1112: - Integrated a patch from Philipp Brenner (BTS entry #21)
1113: Description: "In standard mode it intercepts SIGINT and sends a CTRL+C
1114: (0x03) to the target's vtty_con buffer, while in hypervisor mode it
1115: gracefully shuts down the hypervisor which causes the application to
1116: quit."

1126: -----------
1127: - Added an "exec zone" which is a pool of host executable pages. This
1128: zone is limited by default to 64 Mb for Linux/Unix and 16 Mb for Cygwin.
1129: When the zone is fully used, the JIT structures are flushed (removed the
1130: maximum number of translated pages).
1131: Now, there is no need to disable ExecShield or similar systems.
1132: - Added explicit error message when failing to open an ELF file.
1133: - Fixed getopt_long() usage.

1238: virtual ethernet switch.
1239: - Added "ethsw show_mac_addr_table" to show all MAC addresses learnt by
1240: a virtual ethernet switch.
1241: - Fixed a potential bug with jalr/jr instructions, where the stack is used
1242: to save the return PC. If the instruction in the delay slot returned
1243: directly to the jit main loop (exception,...), the stack would be in
1244: an inconsistent state. This fix is also required for Darwin/x86.
1245:
1246: 27-Jul-2006
1247: -----------
1248: - Stack alignment for Darwin/x86 in memop functions and unknown opcode

1350: 20-Aug-2006
1351: -----------
1352: - Added code to gen_eth module for Cygwin to prevent WinPCAP from giving
1353: back transmitted packets. It requires WinPCAP 0.4-alpha1 or better.

1392: - Added the same to Serial driver (untested).
1393: - Added "unicast limiter" feature to the am79c971 driver, similarly to the
1394: dec21140 driver. Not having this caused the virtual instances to see
1395: unrelated host traffic when using linux_eth/gen_eth NIO and consequently
1396: a bad performance was obtained. Thanks to Greg for noticing that.
1397: - Beginning of rework of PCI subsystem for PCI bridge support.
1398: (Greg noticed that with 12.2T releases, the PCI bus numbering is

1400:
1401: 31-Aug-2006
1402: -----------
1403: - Finished the PCI subsystem rework.
1404: - C7200: Fixed PCI bridge use for midplanes (std: dec21050, vxr: dec21150).
1405:
1406: 01-Sep-2006
1407: -----------
1408: - Finally fixed the Serial problem on C3620 platform (hack in the driver
1409: to trigger interrupts differently).

1411:
1412: 03-Sep-2006
1413: -----------
1414: - Added safety checks to the PCI bus management.
1415: - Added a PLX9060 device (very basic for now).
1416: - Rewritten the PA-POS-OC3 driver to use the new PLX9060 driver.
1417: - Cleanup: removed use of c7200 bay info in drivers (everything uses
1418: PCI for configuration).
1419: - C7200: removed the bay module which contained static definitions of
1420: PCI bus, physical addresses for PA, ... Now everything is handled
1421: dynamically by the PCI subsystem and the remaining drivers (PA-4B,
1422: PA-POS-OC3) have been fixed.
1423: - C3600: removed PCI bus info from the bay module (due to PCI bridge new
1424: code).
1425:
1426: 04-Sep-2006
1427: -----------
1428: - Fixed some typos in comments.

1437: alteration.
1438: - Hypervisor commands now supports a variable number of parameters.
1439: - bugfix: doing a "sh run" and then pressing "Escape" was causing trouble
1440: to the VTTY (the state machine was in an incorrect state).
1441:
1442: 06-Sep-2006
1443: -----------
1444: - Removed erroneous special handling of intra-page jumps in delay slots.
1445: (problem with c3640 12.0(7)T IP+ image).
1446:
1447: 07-Sep-2006
1448: -----------
1449: - C3600: processors ID are now correct.

1464: from running (hypervisor command: c3600 set_iomem <router> <val>).
1465: - C3600: fixed incorrect handling of commands for this platform, which
1466: caused port 0 to be disabled when manipulating other ports.
1467:
1468: 11-Sep-2006
1469: -----------
1470: - Fixed loop overflow in idle pc computation.
1471: - Added base64 encoding/decoding module from Yannick Le Teigner.
1472: - Added hypervisor commands "vm push_config" and "vm extract_config"
1473: to manage IOS configurations. Extracting to base64 is ok (verified with
1474: a third party decoder:
1475: http://www.opinionatedgeek.com/dotnet/tools/Base64Decode/Default.aspx )
1476: - C3600: NVRAM checksum is now correctly computed.
1477:
1478: 12-Sep-2006
1479: -----------
1480: - Following a suggestion of Yannick Le Teigner, applied the optimization
1481: principle to PA-A1 card already used in dec21140, ... Latency is clearly
1482: better (on my system, this dropped from about 150ms to 50 ms).
1483:
1484: 14-Sep-2006
1485: -----------
1486: - Incorrect display of device name in PLX9060 driver.

! 1506: -----------
! 1507: - NM-16ESW: seems to be working! (although there are still a lot of things
! 1508: to do).
! 1509:
! 1510: 28-Sep-2006
! 1511: -----------
! 1512: - Added a hack to allow Ethernet NM to work correctly in 3620/3640
! 1513: (seen when directly attached to the real network with very few packets
! 1514: incoming).
! 1515: - NM-16ESW: proper support for tx ring scatter/gather support.
! 1516: - NM-16ESW: fixed a bug in ARL insertion.
! 1517: - NM-16ESW: send directly BPDU packets to the CPU.
! 1518:
! 1519: 29-Sep-2006
! 1520: -----------
! 1521: - NM-16ESW: added support for "trunks" (ie etherchannel).
! 1522: - Added "Ctrl+p" sequence key to dump Port Adapter / Network Module info
! 1523: (only NM-16ESW reports something at this time).
! 1524:
! 1525: 30-Sep-2006
! 1526: -----------
! 1527: - NM-16ESW: proper management of station movement (etherchannel is handled).
! 1528:
! 1529: 01-Oct-2006
! 1530: -----------
! 1531: - NM-16ESW: added register handling.
! 1532:
! 1533: 02-Oct-2006
! 1534: -----------
! 1535: - NM-16ESW: playing with the port mirroring feature.
! 1536:
! 1537: 04-Oct-2006
! 1538: -----------
! 1539: - Finally understood how to handle link status changes! Now,
! 1540: "shut"/"no shut" is working. Better understanding of MII registers
! 1541: in general.
! 1542:
! 1543: 05-Oct-2006
! 1544: -----------
! 1545: - Fixed bug described in BTS entry #65 (in the case where two virtual
! 1546: addresses point at the same physical address, the JIT can use
! 1547: inappropriate block). This was a "silent" bug.
! 1548:
! 1549: 07-Oct-2006
! 1550: -----------
! 1551: - Modified the hypervisor parser to allow long lines (to upload IOS configs).
! 1552:
! 1553: 09-Oct-2006
! 1554: -----------
! 1555: - NM-16ESW: added ingress and egress port mirroring (todo: BPDU and CDP
! 1556: packets shouldn't be replicated).
