This document lists errata items for FreeBSD 4.4-RELEASE, containing significant information discovered after the release. 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.

This errata document for FreeBSD 4.4-RELEASE will be maintained until the release of FreeBSD 4.5-RELEASE.

1 Introduction

This errata document contains ``late-breaking news'' about FreeBSD 4.4-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version of this errata document actually distributed with the release (for example, on a CDROM distribution) will be out of date by definition, but other copies are kept updated on the Internet and should be consulted as the ``current errata'' for this release.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 4-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

Support for per-user ~/.login_conf files (as documented in login.conf(5)) has been disabled due to incorrect merging of local and global settings. This problem will be fixed in future releases.

A local root vulnerability in UUCP was corrected before the release of FreeBSD 4.4-RELEASE and documented in security advisory FreeBSD-SA-01:62. The release notes mentioned the correction, but not the security advisory, which was issued after the release date of 4.4-RELEASE.

3 System Update Information

The handling of some types of comments in printcap(5) files is faulty. If a comment line ends in :\ (the characters normally used to indicate the continuation of a printer definition), the line following the comment will be parsed as a part of the previous printer definition.

One of the release notes refers to the net.inet.tcp.tcp_seq_genscheme sysctl variable for enabling improved compatability in TCP's initial sequence number generation algorithm. This variable was rendered unnecessary by the adoption of an algorithm based on RFC 1948, which restores proper operation in all cases while maintaining a high level of unpredictability in initial sequence numbers.

The tools/ directory of a FreeBSD CDROM distribution typically contains some DOS programs for i386 machines, such as fdimage.exe and fips.exe. This directory was inadvertently omitted from the initial 4.4-RELEASE ISO images generated by the FreeBSD Project. Corrected versions of the 4.4-install.iso and 4.4-mini.iso ISO images were regenerated on Saturday, 22 September 2001. For those who need these DOS-mode tools and do not wish to re-fetch the ISO images, the contents of the tools/ directory are available by anonymous FTP at ftp://ftp.FreeBSD.org/pub/FreeBSD/tools (many mirrors also have a copy of this directory).

One of the items in the release notes gave a workaround + for hangs during PCCARD ejection, but gave the wrong syntax + for the necessary command. The correct command line is:

+    # pccardc power slot 0
