FreeBSD errata document. Unlike some of the other RELNOTESng
|
|
files, this file should remain as a single SGML file, so that
|
|
the dollar FreeBSD dollar header has a meaningful modification
|
|
time. This file is all but useless without a datestamp on it,
|
|
so we'll take some extra care to make sure it has one.
|
|
|
|
(If we didn't do this, then the file with the datestamp might
|
|
not be the one that received the last change in the document.)

<para>The implementation of the &man.realpath.3; function contains
|
|
a single-byte buffer overflow bug. This may have various

|
impacts, depending on the application using &man.realpath.3; and
|
|
other factors. This bug was fixed on the &release.branch; development
|
|
branch before &release.prev;; &os; &release.prev; is therefore not affected. However, this change
|
|
was not noted in the release documentation. For

<para>&os; &release.prev; includes some new boot loader scripts
|
|
designed to make booting &os; with different options easier.
|
|
This may help diagnose bootstrapping problems. These scripts
|
|
build on the existing Forth-based boot loader scripts (thus,
|
|
<filename>/boot/loader.conf</filename> and other existing loader
|
|
configuration files still apply). They are only installed by
|
|
default for new binary installs on i386 machines. The new
|
|
scripts present a boot-time menu that controls how &os; is
|
|
booted, and include options to turn off ACPI, a <quote>safe
|
|
mode</quote> boot, single-user booting, and verbose booting.
|
|
<quote>Safe mode</quote> booting can be particularly useful when
|
|
compatibility with a system's hardware is uncertain, and sets
|
|
the following kernel tunable variables:</para>
|
|
|
|
<programlisting>hint.acpi.0.disabled=1 # disable ACPI (i386 only)
|
|
hw.ata.ata_dma=0 # disable IDE DMA
|
|
hw.ata.atapi_dma=0 # disable ATAPI/IDE DMA
|
|
hw.ata.wc=0 # disable IDE disk write cache
|
|
hw.eisa_slots=0 # disable probing for EISA devices</programlisting>
|
|
|
|
<para>For new installs on i386 architecture machines,
|
|
&man.sysinstall.8; will try to determine if ACPI was disabled
|
|
via the new boot loader scripts mentioned above, and if so,
|
|
ask if this change should be made permanent.</para>
|
|
|
|
<para>The release notes should have mentioned that work on the
|
|
following features was sponsored by the Defense Advanced
|
|
Research Projects Agency (DARPA): OpenPAM, NSS support, PAE
|
|
support, various MAC framework updates, the GEOM disk geometry
|
|
system.</para>
