> This document lists errata items for FreeBSD 7.1-RELEASE, containing significant information discovered after the release or too late in the release cycle to be otherwise included in the release documentation. This information includes security advisories, as well as news relating to the software or documentation that could affect its operation or usability. An up-to-date version of this document should always be consulted before installing this version of FreeBSD.

## 1 Introduction

This errata document contains “late-breaking news” about FreeBSD 7.1-RELEASE. Before installing this version, it is important to consult this document to learn about any post-release discoveries or problems that may already have been found and fixed.

Any version of this errata document actually distributed with the release (for example, on a CDROM distribution) will be out of date by definition, but other copies are kept updated on the Internet and should be consulted as the “current errata” for this release. These other copies of the errata are located at http://www.FreeBSD.org/releases/, plus any sites which keep up-to-date mirrors of this location.

Source and binary snapshots of FreeBSD 7-STABLE also contain up-to-date copies of this document (as of the time of the snapshot).

For a list of all FreeBSD CERT security advisories, see http://www.FreeBSD.org/security/ or ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/.

## 2 Security Advisories

No advisories.

## 3 Open Issues

[20090105] As in the Announcement of 7.1-RELEASE, certain Intel NICs will come up as igb(4) instead of em(4) in this release. There are only 3 PCI ID's that should have their name changed from em(4) to igb(4):

- 0x10A78086

- 0x10A98086

- 0x10D68086

You should be able to determine if your card will change names by running the following command:

    % pciconf -l
    . . .
    em0@pci0:0:25:0: class=0x020000 card=0x02381028 chip=0x10c08086 rev=0x02 hdr=0x00

and for the line representing your NIC (should be named em on older systems, e.g. em0 or em1, etc) check the fourth column. If that says `chip=0x10a78086` (or one of the other two IDs given above) you will have the adapter's name change.

## 4 Late-Breaking News and Corrections

[20090105] The Release Notes for 7.1-RELEASE should have mentioned that the procstat(1) utility has been added. This is a process inspection utility which provides both some of the missing functionality from procfs(5) and new functionality for monitoring and debugging specific processes.

[20090105] The Release Notes for 7.1-RELEASE should have mentioned changes that the ae(4) driver has been added to provide support for the Attansic/Atheros L2 FastEthernet controllers. This driver is not enabled in `GENERIC` kernels for this release.

[20090105] The Release Notes for 7.1-RELEASE included the following misdescriptions:

- In the entry of linux(4) ABI support, `get_setaffinity()` should have been `sched_setaffinity()`.

[20090105] The Release Notes for 7.1-RELEASE should have mentioned changes that the jme(4) driver has been added to provide support for PCIe adapters based on JMicron JMC250 gigabit Ethernet and JMC260 fast Ethernet controllers.

[20090105] The Release Notes for 7.1-RELEASE should have mentioned changes that the age(4) driver has been added to provide support for Attansic/Atheros L1 gigabit Ethernet controller.

[20090105] The Release Notes for 7.1-RELEASE should have mentioned changes that the malo(4) driver has been added to provide support for Marvell Libertas 88W8335 based PCI network adapters.

[20090105] The Release Notes for 7.1-RELEASE should have mentioned changes that the bm(4) driver has been added to provide support for Apple Big Mac (BMAC) Ethernet controller, found on various Apple G3 models.

[20090105] The Release Notes for 7.1-RELEASE should have mentioned changes that the et(4) driver has been added to provide support for Agere ET1310 10/100/Gigabit Ethernet controller.

[20090105] The Release Notes for 7.1-RELEASE should have mentioned changes that the glxsb(4) driver has been added to provide support for the Security Block in AMD Geode LX processors.

[20090105] The Release Notes for 7.1-RELEASE should have mentioned that FreeBSD now supports multiple routing tables. To enable this, the following steps are needed:

- Add the following kernel configuration option and rebuild the kernel. The `2` is the number of FIB (Forward Information Base, synonym for a routing table here). The maximum value is 16.

      options    ROUTETABLES=2

  The procedure for rebuilding the FreeBSD kernel is described in the FreeBSD Handbook.

  This number can be modified on boot time. To do so, add the following to `/boot/loader.conf` and reboot the system:

      net.fibs=6

- Set a loader tunable `net.my_fibnum` if needed. This means the default number of routing tables. If not specified, `0` will be used.

- Set a loader tunable `net.add_addr_allfibs` if needed. This enables to add routes to all FIBs for new interfaces by default. When this is set to `0`, it will only allocate routes on interface changes for the FIB of the caller when adding a new set of addresses to an interface. Note that this tunable is set to `1` by default.

To select one of the FIBs, the new setfib(1) utility can be used. This set an associated FIB with the process. For example:

    # setfib -3 ping target.example.com

The FIB #3 will be used for the ping(8) command.

The FIB which the packet will be associated with will be determined in the following rules:

- All packets which have a FIB associated with them will use the FIB. If not, FIB #0 will be used.

- A packet received on an interface for forwarding uses FIB #0.

- A TCP listen socket associated with an FIB will generate accept sockets which are associated with the same FIB.

- A packet generated in response to other packet uses the FIB associated with the packet being responded to.

- A packet generated on tunnel interfaces such as gif(4) and tun(4) will be encapsulated using the FIB of the process which set up the tunnel.

- Routing messages will be associated with the process's FIB.

Also, the ipfw(8) now supports an action rule `setfib`. The following action:

    setfib fibnum

will make the matched packet use the FIB specified in `fibnum`. The rule processing continues at the next rule.
