20070422: |
|
The way OS emulations lookup filenames inside the emulation root |
|
has been changed. Rather than modify the pathname (and copy back |
|
to userspace) namei() and lookup() directly check the emulation |
|
root. One side effect is that absolute symlinks inside the emulated |
|
root filesytem will be relative to that filesystem - unless they |
|
start /../ this is useful when the emulated root is a real install |
|
that has such links. |
|
This might affect symlinks that have been added to reference outside |
|
the emulated root. |

20070412: |
|
The pckbc driver on sgimips IP32 has been removed. Use macekbc |
|
instead. See the GENERIC32_IP3x kernel configuration for an |
|
example. |

src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so |
|
on many platforms due to incorrect flags settings. If you |
|
updated and built after about 20070315, do "nbmake-$arch |
|
cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a |
|
rebuild of object files that might have been built |
|
incorrectly, and ensure that you have at least |
|
src/lib/libc/Makefile 1.130. |
|
|
|
20070210: |
|
src/sys/sys/{sa.h,savar.h} were removed. |
|
find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \ |
|
| xargs egrep -l '/sa.h|/savar.h' | xargs rm |
|
will allow dependencies on those files to get get rebuilt |
|
|
|
20070209: |
|
The threading model was changed when the newlock2 branch |
|
was merged to NetBSD-current. If you boot with a new |
|
kernel (version 4.99.10), then you also need a new pthread |
|
library (/usr/lib/libpthread.so.0.7). If you boot with |
|
an old kernel, then you need the old pthread library |
|
(/usr/lib/libpthread.so.0.6). Provided you keep the kernel and |
|
the pthread library in sync, old threaded applications should |
|
continue to work with an old or new kernel. Note that named(8) |
|
is the only threaded application in the base system. |
|

20061214: |
|
Following the move of string_to_flags() and flags_to_string() |
|
from the bin/ls/ sources to libutil, users doing UPDATE builds |
|
will need to do a "make cleandir" in |
|
tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/, |
|
bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/, |
|
usr.bin/xinstall/, libexec/ftpd/, rescue/, as well |
|
as the installation images in distrib/ |
|
in order to excise stale references to the old stat_flags.h header |
|
file in the ls sources -- stat_flags.h has been removed. |
|
|
|
20061108: |
|
The configure script used in the src/tools/gcc compiler has been |
|
changed to indicate that our libc has ssp support built-in and |
|
does not depend on -lssp and -lssp-nonshared. You'll need to |
|
make clean in src/tools/gcc first to rebuild the compiler. |
|
|
|
20061009: |
|
The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer |
|
available. Use net.inet{,6}.tcp{,6}.congctl.selected instead. |
|
|
|
20060814: |
|
The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been |
|
withdrawn. Use vidcvideo and pckbd instead. See the GENERIC |
|
kernel configuration for an example. X servers from the last |
|
few years should cope. |
|
|
|
20060703: |
|
MPACPI is no more. We always configure PCI interrupts using ACPI |
|
if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed |
|
to ACPI_SCANPCI. Thanks to work from fvdl. |
|
|
|
20060627: |
|
socket(2) has changed, and its system call has been versioned. |
|
For userlands with the old version of socket(2), make sure that |
|
your kernel has 'options COMPAT_30' set, or else 'bad system call' |
|
errors will result. |
|
|
|
20060526: |
|
The kernel linker scripts for i386 and xen |
|
(sys/arch/i386/conf/kern.ldscript*) were changed to set the |
|
load address correctly, for the benefit of MULTIBOOT boot loaders |
|
(like Grub). If you use a linker (ld) older than from 2006/04/17, it |
|
will be unable to link the kernel because of a bug and ld will fail |
|
with an error like: |
|
../../../../arch/i386/conf/kern.ldscript:45 \ |
|
non constant expression for load base |
|
You need to update at least src/gnu/dist/binutils/ld and recompile |
|
and install the linker. If using the build.sh script, the easiest |
|
way is with a "build.sh tools" command, with any other options |
|
that you use normally. When using build.sh, the linker binary is |
|
installed as ${TOOLDIR}/bin/i386--netbsdelf-ld. |
|
|
|
20060131: |
|
the protocol between the sparc64 bootloader (ofwboot) and |
|
the kernel was changed. Before installing a new kernel, |
|
you need to update ofwboot. After a full build, just copy |
|
/usr/mdec/ofwboot to /, or do a rebuild of |
|
src/sys/arch/sparc/stand/ofwboot and install the result to /. |
|
|
|
20050917: |
|
arch/*/conf/std.* was changed to include conf/std, which |
|
contains MI options previously enabled by default. |
|
If you have kernel config files which doesn't include |
|
arch/*/conf/std.*, you need to edit them to include conf/std |
|
to get the previous configuration. |
|
|
|
20050830: |
|
named.conf was moved from /etc/namedb to /etc. |
|
postinstall(8) migrates this during interactive use. |
|
Users of MKUPDATE=yes will need to manually rectify |
|
this in their DESTDIR. |
|
|
|
20050825: |
|
Some data structures in sys/device.h, related to interface |
|
attributes and locator names, were changed. config(1) was |
|
modified to emit the new data structures. |
|
Thus usr.bin/config must be updated (and run on the kernel |
|
configuration file) before a new kernel can be built. |
|
|
|
20050531: |
|
genassym.sh(8) was moved to genassym(1). You need to either build |
|
tools first or install the version of genassym from /usr/bin before |
|
you can build a kernel again. |
|
|
|
20050520: |
|
Because a kernfs bug which xentools relies on was fixed, |
|
xentools up to xentools20-2.0.3nb4 won't work with new kernel. |
|
|
|
20050417: |
|
postinstall(8) was moved from /etc to /usr/sbin and made part |
|
of the "base" set, to make it easier to invoke after an |
|
upgrade. |
|
|
|
20050325: |
|
pcppi(4) was separated in two devices, adding attimer(4). Be sure |
|
to add a config line for an attimer(4) device in your kernel |
|
configuration, or you won't be able to set the pitch of the beep |
|
with wsconsctl. Depending on the default value for the pitch, you |
|
might even not hear any more beep. Also, it is advised to attach both |
|
devices the same way (i.e., both on isa or both on acpi) or the |
|
pcppi(4) device may fail to find the attimer(4) one. |
|
|
|
20050211: |
|
Fixes to tools/Makefile.gnuhost may cause UPDATE=1 builds in |
|
some of the cross tools to fail if they use configure. Some configure's |
|
cache the environment passed in and notice the new environment is |
|
different and abort. Doing a clean in tools/ should be enough to |
|
make a build continue. |
|
|
|
20050109: |
|
Since su is using pam by default now, make sure that you have |
|
/etc/pam.d populated (postinstall will do that automatically |
|
for you). Otherwise su will fail open (i.e. will not require |
|
a password). |
|
|
|
20041229: |
|
Make had a path resolution bug that manifested itself as not |
|
being able to install openpam.3. This bug has been fixed, but |
|
you might need to rebuild make manually first to get through |
|
the build. |
|
|
|
20041201: |
|
Userland programs have been changed to use /dev/bpf instead of |
|
/dev/bpfX. You need to create that device by installing a new |
|
MAKEDEV and running it, or mv /dev/bpf0 /dev/bpf && rm /dev/bpf[0-9]* |
|
|
|
20041006: |
|
|
|
A bug was introduced into /bin/sh (var.c rev 1.35) which causes |
|
variables to not export correctly to subshells in all cases. This |
|
will cause builds to break if that version of /bin/sh is installed |
|
on the system. The proper version of /bin/sh can be verified with: |
|
|
|
ident /bin/sh | grep var |
|
|
|
Any /bin/sh w. version 1.35 will not work and needs to be updated |
|
before attempting a build. |
