An IPv6 support of ipfw was enabled by default. If you don't |
| 13 |
want to filter an IPv6 by ipfw, please add following line into |
| 14 |
your ipfw rule: |
| 15 |
|
| 16 |
pass ip6 from any to any |
| 17 |
|

Now most modules get their build-time options from the kernel |
| 20 |
configuration file. A few modules still have fixed options |
| 21 |
due to their non-conformant implementation, but they will be |
| 22 |
corrected eventually. You may need to review the options of |
| 23 |
the modules in use, explicitly specify the non-default options |
| 24 |
in the kernel configuration file, and rebuild the kernel and |
| 25 |
modules afterwards. |
| 26 |
|
| 27 |
20060122: |
| 28 |
/etc/rc.d/ppp-user has been renamed to /etc/rc.d/ppp. |
| 29 |
Its /etc/rc.conf.d configuration file has been `ppp' from |
| 30 |
the beginning, and hence there is no need to touch it. |
| 31 |
|
| 32 |
20060113: |
| 33 |
si(4)'s device files now contain the unit number. |
| 34 |
Uses of {cua,tty}A[0-9a-f] should be replaced by {cua,tty}A0[0-9a-f]. |
| 35 |
|
| 36 |
20051230: |
| 37 |
A lot of fixes and new features in the soundsystem. To get all |
| 38 |
benefits, you may want to recompile mplayer (if installed) after |
| 39 |
booting the new world. |
| 40 |
|
| 41 |
20051222: |
| 42 |
Bug fixes to the trimdomain(3) function in libutil may result in |
| 43 |
slight changes to the host names appearing in log files under |
| 44 |
relatively rare circumstances. |
| 45 |
|
| 46 |
20051220: |
| 47 |
Scripts in the local_startup directories (as defined in |
| 48 |
/etc/defaults/rc.conf) that have the new rc.d semantics will |
| 49 |
now be run as part of the base system rcorder. If there are |
| 50 |
errors or problems with one of these local scripts, it could |
| 51 |
cause boot problems. If you encounter such problems, boot in |
| 52 |
single user mode, remove that script from the */rc.d directory. |
| 53 |
Please report the problem to the port's maintainer, and the |
| 54 |
freebsd-ports@freebsd.org mailing list. |
| 55 |
|
| 56 |
20051215: |
| 57 |
The setkey(8) utility was moved from /usr/sbin/setkey to /sbin/setkey. |
| 58 |
You may want to update scripts which depend on its location. |
| 59 |
|
| 60 |
20051108: |
| 61 |
rp(4)'s device files now contain the unit number. |
| 62 |
Uses of {cua,tty}R[0-9a-f] should be replaced by {cua,tty}R0[0-9a-f]. |
| 63 |
|
| 64 |
20051101: |
| 65 |
FreeBSD 6.0-RELEASE |
| 66 |
|
| 67 |
20051001: |
| 68 |
kern.polling.enable sysctl MIB is now deprecated. Use ifconfig(8) |
| 69 |
to turn polling(4) on your interfaces. |
| 70 |
|
| 71 |
20050722: |
| 72 |
The ai_addrlen of a struct addrinfo was changed to a socklen_t |
| 73 |
to conform to POSIX-2001. This change broke an ABI |
| 74 |
compatibility on 64 bit architecture. You have to recompile |
| 75 |
userland programs that use getaddrinfo(3) on 64 bit |
| 76 |
architecture. |
| 77 |
|
| 78 |
20050711: |
| 79 |
RELENG_6 branched here. |
| 80 |
|
| 81 |
20050629: |
| 82 |
The pccard_ifconfig rc.conf variable has been removed and a new |
| 83 |
variable, ifconfig_DEFAULT has been introduced. Unlike |
| 84 |
pccard_ifconfig, ifconfig_DEFAULT applies to ALL interfaces that |
| 85 |
do not have ifconfig_ifn entries rather than just those in |
| 86 |
removable_interfaces. |
| 87 |
|
| 88 |
20050616: |
| 89 |
Some previous versions of PAM have permitted the use of |
| 90 |
non-absolute paths in /etc/pam.conf or /etc/pam.d/* when referring |
| 91 |
to third party PAM modules in /usr/local/lib. A change has been |
| 92 |
made to require the use of absolute paths in order to avoid |
| 93 |
ambiguity and dependence on library path configuration, which may |
| 94 |
affect existing configurations. |
| 95 |
|
| 96 |
20050610: |
| 97 |
Major changes to network interface API. All drivers must be |
| 98 |
recompiled. Drivers not in the base system will need to be |
| 99 |
updated to the new APIs. |
| 100 |
|
| 101 |
20050609: |
| 102 |
Changes were made to kinfo_proc in sys/user.h. Please recompile |
| 103 |
userland, or commands like `fstat', `pkill', `ps', `top' and `w' |
| 104 |
will not behave correctly. |
| 105 |
|
| 106 |
The API and ABI for hwpmc(4) have changed with the addition |
| 107 |
of sampling support. Please recompile lib/libpmc(3) and |
| 108 |
usr.sbin/{pmcstat,pmccontrol}. |
| 109 |
|
| 110 |
20050606: |
| 111 |
The OpenBSD dhclient was imported in place of the ISC dhclient |
| 112 |
and the network interface configuration scripts were updated |
| 113 |
accordingly. If you use DHCP to configure your interfaces, you |
| 114 |
must now run devd. Also, DNS updating was lost so you will need |
| 115 |
to find a workaround if you use this feature. |
| 116 |
|
| 117 |
20050605: |
| 118 |
if_bridge was added to the tree. This has changed struct ifnet. |
| 119 |
Please recompile userland and all network related modules. |
| 120 |
|
| 121 |
20050603: |
| 122 |
The n_net of a struct netent was changed to an uint32_t, and |
| 123 |
1st argument of getnetbyaddr() was changed to an uint32_t, to |
| 124 |
conform to POSIX-2001. These changes broke an ABI |
| 125 |
compatibility on 64 bit architecture. With these changes, |
| 126 |
shlib major of libpcap was bumped. You have to recompile |
| 127 |
userland programs that use getnetbyaddr(3), getnetbyname(3), |
| 128 |
getnetent(3) and/or libpcap on 64 bit architecture. |
| 129 |
|
| 130 |
20050528: |
| 131 |
Kernel parsing of extra options on '#!' first lines of shell |
| 132 |
scripts has changed. Lines with multiple options likely will |
| 133 |
fail after this date. For full details, please see |
| 134 |
http://people.freebsd.org/~gad/Updating-20050528.txt |
| 135 |
|
| 136 |
20050503: |
| 137 |
The packet filter (pf) code has been updated to OpenBSD 3.7 |
| 138 |
Please note the changed anchor syntax and the fact that |
| 139 |
authpf(8) now needs a mounted fdescfs(5) to function. |
| 140 |
|
| 141 |
20050415: |
| 142 |
The NO_MIXED_MODE kernel option has been removed from the i386 |
| 143 |
amd64 platforms as its use has been superceded by the new local |
| 144 |
APIC timer code. Any kernel config files containing this option |
| 145 |
should be updated. |
| 146 |
|
| 147 |
20050227: |
| 148 |
The on-disk format of LC_CTYPE files was changed to be machine |
| 149 |
independent. Please make sure NOT to use NO_CLEAN buildworld |
| 150 |
when crossing this point. Crossing this point also requires |
| 151 |
recompile or reinstall of all locale depended packages. |
| 152 |
|
| 153 |
20050225: |
| 154 |
The ifi_epoch member of struct if_data has been changed to |
| 155 |
contain the uptime at which the interface was created or the |
| 156 |
statistics zeroed rather then the wall clock time because |
| 157 |
wallclock time may go backwards. This should have no impact |
| 158 |
unless an snmp implementation is using this value (I know of |
| 159 |
none at this point.) |
| 160 |
|
| 161 |
20050224: |
| 162 |
The acpi_perf and acpi_throttle drivers are now part of the |
| 163 |
acpi(4) main module. They are no longer built separately. |
| 164 |
|
| 165 |
20050223: |
| 166 |
The layout of struct image_params has changed. You have to |
| 167 |
recompile all compatibility modules (linux, svr4, etc) for use |
| 168 |
with the new kernel. |
| 169 |
|
| 170 |
20050223: |
| 171 |
The p4tcc driver has been merged into cpufreq(4). This makes |
| 172 |
"options CPU_ENABLE_TCC" obsolete. Please load cpufreq.ko or |
| 173 |
compile in "device cpufreq" to restore this functionality. |
| 174 |
|
| 175 |
20050220: |
| 176 |
The responsibility of recomputing the file system summary of |
| 177 |
a SoftUpdates-enabled dirty volume has been transferred to the |
| 178 |
background fsck. A rebuild of fsck(8) utility is recommended |
| 179 |
if you have updated the kernel. |
| 180 |
|
| 181 |
To get the old behavior (recompute file system summary at mount |
| 182 |
time), you can set vfs.ffs.compute_summary_at_mount=1 before |
| 183 |
mounting the new volume. |
| 184 |
|
| 185 |
20050206: |
| 186 |
The cpufreq import is complete. As part of this, the sysctls for |
| 187 |
acpi(4) throttling have been removed. The power_profile script |
| 188 |
has been updated, so you can use performance/economy_cpu_freq in |
| 189 |
rc.conf(5) to set AC on/offline cpu frequencies. |
| 190 |
|
| 191 |
20050206: |
| 192 |
NG_VERSION has been increased. Recompiling kernel (or ng_socket.ko) |
| 193 |
requires recompiling libnetgraph and userland netgraph utilities. |
| 194 |
|
| 195 |
20050114: |
| 196 |
Support for abbreviated forms of a number of ipfw options is |
| 197 |
now deprecated. Warnings are printed to stderr indicating the |
| 198 |
correct full form when a match occurs. Some abbreviations may |
| 199 |
be supported at a later date based on user feedback. To be |
| 200 |
considered for support, abbreviations must be in use prior to |
| 201 |
this commit and unlikely to be confused with current key words. |
| 202 |
|
| 203 |
20041221: |
| 204 |
By a popular demand, a lot of NOFOO options were renamed |
| 205 |
to NO_FOO (see bsd.compat.mk for a full list). The old |
| 206 |
spellings are still supported, but will cause annoying |
| 207 |
warnings on stderr. Make sure you upgrade properly (see |
| 208 |
the COMMON ITEMS: section later in this file). |
| 209 |
|
| 210 |
20041219: |
| 211 |
Auto-loading of ancillary wlan modules such as wlan_wep has |
| 212 |
been temporarily disabled; you need to statically configure |
| 213 |
the modules you need into your kernel or explicitly load them |
| 214 |
prior to use. Specifically, if you intend to use WEP encryption |
| 215 |
with an 802.11 device load/configure wlan_wep; if you want to |
| 216 |
use WPA with the ath driver load/configure wlan_tkip, wlan_ccmp, |
| 217 |
and wlan_xauth as required. |
| 218 |
|
| 219 |
20041213: |
| 220 |
The behaviour of ppp(8) has changed slightly. If lqr is enabled |
| 221 |
(``enable lqr''), older versions would revert to LCP ECHO mode on |
| 222 |
negotiation failure. Now, ``enable echo'' is required for this |
| 223 |
behaviour. The ppp version number has been bumped to 3.4.2 to |
| 224 |
reflect the change. |
| 225 |
|
| 226 |
20041201: |
| 227 |
The wlan support has been updated to split the crypto support |
| 228 |
into separate modules. For static WEP you must configure the |
| 229 |
wlan_wep module in your system or build and install the module |
| 230 |
in place where it can be loaded (the kernel will auto-load |
| 231 |
the module when a wep key is configured). |
| 232 |
|
| 233 |
20041201: |
| 234 |
The ath driver has been updated to split the tx rate control |
| 235 |
algorithm into a separate module. You need to include either |
| 236 |
ath_rate_onoe or ath_rate_amrr when configuring the kernel. |
| 237 |
|
| 238 |
20041116: |
| 239 |
Support for systems with an 80386 CPU has been removed. Please |
| 240 |
use FreeBSD 5.x or earlier on systems with an 80386. |
| 241 |
|
| 242 |
20041110: |
| 243 |
We have had a hack which would mount the root filesystem |
| 244 |
R/W if the device were named 'md*'. As part of the vnode |
| 245 |
work I'm doing I have had to remove this hack. People |
| 246 |
building systems which use preloaded MD root filesystems |
| 247 |
may need to insert a "/sbin/mount -u -o rw /dev/md0 /" in |
| 248 |
their /etc/rc scripts. |
| 249 |
|
| 250 |
20041104: |
| 251 |
FreeBSD 5.3 shipped here. |
| 252 |
|
| 253 |
20041102: |
| 254 |
The size of struct tcpcb has changed again due to the removal |
| 255 |
of RFC1644 T/TCP. You have to recompile userland programs that |
| 256 |
read kmem for tcp sockets directly (netstat, sockstat, etc.) |
| 257 |

COMMON ITEMS: |
| 268 |
|
| 269 |
General Notes |
| 270 |
------------- |
| 271 |
Avoid using make -j when upgrading. From time to time in the |
| 272 |
past there have been problems using -j with buildworld and/or |
| 273 |
installworld. This is especially true when upgrading between |
| 274 |
"distant" versions (eg one that cross a major release boundary |
| 275 |
or several minor releases, or when several months have passed |
| 276 |
on the -current branch). |
| 277 |
|
| 278 |
Sometimes, obscure build problems are the result of environment |
| 279 |
poisoning. This can happen because the make utility reads its |
| 280 |
environment when searching for values for global variables. |
| 281 |
To run your build attempts in an "environmental clean room", |
| 282 |
prefix all make commands with 'env -i '. See the env(1) manual |
| 283 |
page for more details. |
| 284 |
|
| 285 |
Due to several updates to the build infrastructure, source |
| 286 |
upgrades from versions prior to 5.3 no longer supported. |
| 287 |
|
| 288 |
When upgrading from one major version to another it is generally |
| 289 |
best to upgrade to the latest code in the currently installed branch |
| 290 |
first, then do an upgrade to the new branch. This is the best-tested |
| 291 |
upgrade path, and has the highest probability of being successful. |
| 292 |
Please try this approach before reporting problems with a major |
| 293 |
version upgrade. |
| 294 |
|
| 295 |
To build a kernel |
| 296 |
----------------- |
| 297 |
If you are updating from a prior version of FreeBSD (even one just |
| 298 |
a few days old), you should follow this procedure. With a |
| 299 |
/usr/obj tree with a fresh buildworld, |
| 300 |
make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE |
| 301 |
make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE |
| 302 |
|
| 303 |
To test a kernel once |
| 304 |
--------------------- |
| 305 |
If you just want to boot a kernel once (because you are not sure |
| 306 |
if it works, or if you want to boot a known bad kernel to provide |
| 307 |
debugging information) run |
| 308 |
make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel |
| 309 |
nextboot -k testkernel |
| 310 |
|
| 311 |
To just build a kernel when you know that it won't mess you up |
| 312 |
-------------------------------------------------------------- |
| 313 |
This assumes you are already running a 6.X system. Replace |
| 314 |
${arch} with the architecture of your machine (e.g. "i386", |
| 315 |
"alpha", "amd64", "ia64", "pc98", "sparc64", etc). |
| 316 |
|
| 317 |
cd src/sys/${arch}/conf |
| 318 |
config KERNEL_NAME_HERE |
| 319 |
cd ../compile/KERNEL_NAME_HERE |
| 320 |
make depend |
| 321 |
make |
| 322 |
make install |
| 323 |
|
| 324 |
If this fails, go to the "To build a kernel" section. |
| 325 |
|
| 326 |
To rebuild everything and install it on the current system. |
| 327 |
----------------------------------------------------------- |
| 328 |
# Note: sometimes if you are running current you gotta do more than |
| 329 |
# is listed here if you are upgrading from a really old current. |
| 330 |

To cross-install current onto a separate partition |
| 344 |
-------------------------------------------------- |
| 345 |
# In this approach we use a separate partition to hold |
| 346 |
# current's root, 'usr', and 'var' directories. A partition |
| 347 |
# holding "/", "/usr" and "/var" should be about 2GB in |
| 348 |
# size. |

cd src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd |
| 358 |
make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} |
| 359 |
cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd |
| 360 |
<edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> |
| 361 |
<reboot into current> |
| 362 |
<do a "native" rebuild/install as described in the previous section> |
| 363 |
<maybe install compatibility libraries from src/lib/compat> |
| 364 |
<reboot> |
| 365 |
|

Make sure that you've read the UPDATING file to understand the |
| 381 |
tweaks to various things you need. At this point in the life |
| 382 |
cycle of current, things change often and you are on your own |
| 383 |
to cope. The defaults can also change, so please read ALL of |
| 384 |
the UPDATING entries. |
| 385 |
|
| 386 |
Also, if you are tracking -current, you must be subscribed to |
| 387 |
freebsd-current@freebsd.org. Make sure that before you update |
| 388 |
your sources that you have read and understood all the recent |
| 389 |
messages there. If in doubt, please track -stable which has |
| 390 |
much fewer pitfalls. |
| 391 |
|
| 392 |
[1] If you have third party modules, such as vmware, you |
| 393 |
should disable them at this point so they don't crash your |

Also, when doing a major release upgrade, it is required that |
| 403 |
you boot into single user mode to do the installworld. |
| 404 |
|
| 405 |
[4] Note: This step is non-optional. Failure to do this step |
| 406 |
can result in a significant reduction in the functionality of the |
| 407 |
system. Attempting to do it by hand is not recommended and those |
| 408 |
that pursue this avenue should read this file carefully, as well |
| 409 |
as the archives of freebsd-current and freebsd-hackers mailing lists |
| 410 |
for potential gotchas. |
| 411 |
|
| 412 |
[5] Usually this step is a noop. However, from time to time |
| 413 |
you may need to do this if you get unknown user in the following |
| 414 |
step. It never hurts to do it all the time. |
| 415 |
|
| 416 |
[8] In order to have a kernel that can run the 5.x binaries |
| 417 |
needed to do an installworld, you must include the COMPAT_FREEBSD5 |
| 418 |
option in your kernel. Failure to do so may leave you with a system |
| 419 |
that is hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 |
| 420 |
is required to run the 5.x binaries on more recent kernels. |
| 421 |
|
| 422 |
Make sure that you merge any new devices from GENERIC since the |
| 423 |
last time you updated your kernel config file. |
| 424 |
|
| 425 |
[9] When checking out sources, you must include the -P flag to have |
| 426 |
cvs prune empty directories. |
| 427 |
|
| 428 |
If CPUTYPE is defined in your /etc/make.conf, make sure to use the |
| 429 |
"?=" instead of the "=" assignment operator, so that buildworld can |
| 430 |
override the CPUTYPE if it needs to. |
| 431 |
|
| 432 |
MAKEOBJDIRPREFIX must be defined in an environment variable, and |
| 433 |
not on the command line, or in /etc/make.conf. buildworld will |
| 434 |
warn if it is improperly defined. |

This file contains a list, in reverse chronological order, of major |
| 438 |
breakages in tracking -STABLE. Not all things will be listed here, |
| 439 |
and it only starts on October 16, 2004. Updating files can found in |
| 440 |
previous releases if your system is older than this. |
