This document lists errata items for FreeBSD 10.2-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.
This errata document for FreeBSD 10.2-RELEASE will be maintained until the release of FreeBSD 10.3-RELEASE.
This errata document contains “late-breaking news” about FreeBSD 10.2-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version of this errata document actually distributed with the release (for example, on a CDROM distribution) will be out of date by definition, but other copies are kept updated on the Internet and should be consulted as the “current errata” for this release.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 https://www.FreeBSD.org/releases/, plus any sites which keep up-to-date mirrors of this location.
Source and binary snapshots of FreeBSD 10.2-STABLE also contain up-to-date copies of this document (as of the time of the snapshot).

FreeBSD/i386 10.2-RELEASE running as a guest + syscons(4).
Insufficient check of supported pkg(7) + signature methods.
FreeBSD/i386 10.2-RELEASE running as a guest operating system on VirtualBox can have a problem with disk I/O access. It depends on some specific hardware configuration and does not depend on a specific version of VirtualBox or host operating system.
It has been reported that instability may be present on virtual machines running on other hypervisors, such as Xen or KVM.
It causes various errors and makes FreeBSD quite unstable.
Although the cause is still unclear, disabling unmapped I/O
works as a workaround. To disable it, choose
Escape to loader prompt in the boot menu
and enter the following lines from loader(8) prompt,
after an OK:
set vfs.unmapped_buf_allowed=0 boot
Note that the following line has to be added to
/boot/loader.conf after a boot. It
disables unmapped I/O at every boot:
vfs.unmapped_buf_allowed=0
FreeBSD/i386 10.2-RELEASE installed on ZFS
may crash during boot when the ZFS pool mount is attempted
while booting an unmodified GENERIC
kernel.
As described in /usr/src/UPDATING
entry 20121223, rebuilding the kernel
with options KSTACK_PAGES=4 has been
observed to resolve the boot-time crash. This, however, is
not an ideal solution for inclusion in the
GENERIC kernel configuration, as
increasing KSTACK_PAGES implicitly
decreases available usermode threads in an environment that
is already resource-starved.
Taking into account the heavy resource requirements of
ZFS, in addition to the i386-specific tuning
requirements for general workloads, using ZFS with the
FreeBSD/i386 GENERIC kernel
is strongly discouraged.
If installing FreeBSD/i386 on ZFS, it is possible to
configure the system after installation to increase the
KSTACK_PAGES.
When prompted by bsdinstall(8) to perform additional post-installation configuration to the system, select .
This procedure requires the system sources available
locally. If the System source code
distribution was not selected during installation, it can
be obtained using svnlite:
#mkdir -p /usr/src#svnlite co svn://svn.freebsd.org/base/releng/10.2 /usr/src
Build the kernel-toolchain required
to rebuild the kernel:
# make -C /usr/src kernel-toolchainNext, create a kernel configuration file to increase the
KSTACK_PAGES option:
#printf "include GENERIC\noptions KSTACK_PAGES=4\n" >/usr/src/sys/i386/conf/ZFS
Then build and install the
ZFS kernel:
#make -C /usr/src buildkernel KERNCONF=ZFS#make -C /usr/src installkernel KERNCONF=ZFS
It is extremely important to take note that, by
default, freebsd-update(8) will install the
GENERIC kernel configuration, and
as such, freebsd-update(8) consumers are strongly
encouraged to avoid FreeBSD-provided kernel binary upgrades
with such configurations.
Due to an incompatibility between bsdconfig(8) and pkg(8), packages included on the FreeBSD dvd installer will not be recognized by bsdconfig(8).
To install packages from the dvd1.iso
installer, create the /dist target directory, and
manually mount the dvd1.iso
ISO:
#mkdir -p /dist#mount -t cd9660 /dev/cd0/dist
Be sure to use the correct /dev device path for the
dvd1.iso ISO
installer.
Next, set REPOS_DIR to the path of the
repos/ directory
within the installer so pkg(8) will use the correct
repository metadata.
If using sh(1):
# export REPOS_DIR=/dist/packages/reposIf using csh(1):
# setenv REPOS_DIR /dist/packages/reposKeep in mind that REPOS_DIR will need
to be set again after the current shell session is
terminated, if continuing to use the packages provided on
the dvd1.iso installer.
Finally, bootstrap pkg(8) from the ISO, and install required packages:
#pkg bootstrap#pkg installxorg-serverxorggnome3[...]
An issue was discovered where the netstat(1)
-s option will cause a segmentation fault
on systems with IPSEC compiled into the
kernel. The issue was resolved in the
stable/10 branch, and an Errata Notice is
planned after 10.2-RELEASE is released.
[2015-08-19] Resolved as FreeBSD-EN-15:12.
An issue was discovered that causes make(1) to generate noisy output when doing source-based upgrades from FreeBSD 9.3 and earlier. The issue was reported in PR 202277, and after investigation and determining the issue does not cause source-based upgrades to fail, a post-release Errata Notice is planned.
[2015-08-19] Resolved as FreeBSD-EN-15:11.
An issue with FreeBSD virtual machines with
vagrant was discovered that
affects the VirtualBox where the
virtual machine will not start on the initial boot invoked
with vagrant up.
The issue is due to the virtual machine
MAC being unset, as FreeBSD does not provide
a default Vagrantfile.
It has been observed, however, that a subsequent
invocation of vagrant up will allow the
virtual machine to successfully boot, allowing access via
vagrant ssh.
[2015-08-16] An error was discovered in the release
notes for FreeBSD 10.2-RELEASE regarding the
drm device driver. The entry for r282199
states the driver was updated to match the version Linux®
3.8.13 version, however the entry should have noted the
change affects device-independent code, and does not bring
the drm driver fully in line with the
stated Linux® version.
