                     13:        added, and the restrictive fsck checks have been reenabled
                     14:        when using those layouts.  If you have been using -current
                     15:        since 20030402, you may find that fsck again signals fatal
                     16:        superblock mismatches.  To work around, you can use
1.104   ! dbj        17:        fsck_ffs -b 32 -c 4 to restore an alternate superblock
        !            18:        and complete the filesystem upgrade.

                     36:        code has been deprecated to COMPAT_16. Make sure that your running
                     37:        kernel has COMPAT_16 enabled before building userland.

                     59:        Due to bugs in the export handling code, invalid export lines
                     60:        were accepted before and caused the kernel to panic when
                     61:        mountd got restarted because it freed memory that had already
                     62:        been freed. This has been fixed and the kernel checks
                     63:        export addresses very strictly. If you upgrade your kernel,
                     64:        make sure you also upgrade mountd, because if your export
                     65:        file contains lines with an old inet4 address syntax (i.e.
                     66:        a.b.c or a.b or a), they will get rejected by the new kernel.

                     69:        The superblock layout for FFS was changed.  If you have 1.6
                     70:        fsck binaries, they will signal a fatal superblock mismatch
                     71:        with the first alternate, because they compare too many
                     72:        fields (even ones that aren't useful).  If possible, upgrade
                     73:        your fsck_ffs binary before using a new kernel.
                     74:        None of this signals actual filesystem damage.

                     77:        sendmail version 8.12.8 was imported.  Since sendmail is
                     78:        now setgid to the smmsp group, and runs in "collection"
                     79:        mode for most common activities, there is a new config
                     80:        file called submit.cf that needs to live in /etc/mail.

                     82:        is named netbsd-msp.cf.  Upgrading your regular sendmail
                     83:        configuration file is also strongly advised.
                     84:
                     85:        See the section named "MESSAGE SUBMISSION PROGRAM" in

                     87:        information.

                     98:        "${DESTDIR}" from path names.
                     99:        This only affects people building with UNPRIVED.
                    100:        For complete safety, remove the DESTDIR entirely and

                    113:

                    115:        this option (using ${NETBSDSRCDIR}/etc), so if you
1.83      kei       116:        use USETOOLS==no, you may have to rebuild and

                    136:        (and their companions crtbeginS.o and crtendS.o) were

                    138:        This means that libtool needs to be rebuilt once the

                    140:        libtool will cause it to automatically notice the new

                    145:        which lack _init() and _fini() routines, which means that

                    150:        corrected.
                    151:
                    152:        NetBSD ARM ELF uses the soft-VFP floating point model by
                    153:        default.  However, the assembler lacked support for marking
                    154:        objects as using the VFP floating point format, and the
1.79      wiz       155:        compiler was not properly passing the flag indicating "soft-VFP"
1.75      thorpej   156:        to the assembler.
                    157:
                    158:        Unfortunately, this means that the linker will now consider
                    159:        old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
                    160:        incompatible with new (properly marked) objects.
                    161:
                    162:        The problem will only manifest itself if you attempt to compile
                    163:        a new program using the fixed toolchain, and link that program
                    164:        against old libraries which do not have the proper "softvfp"
                    165:        markings.  ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES

                    167:
                    168:        The only work-around for the problem is to recompile all of
                    169:        the libraries on the system.  The easiest way to do this for
1.79      wiz       170:        system libraries is to install a binary snapshot; they are

1.75      thorpej   172:        have installed which supply libraries will have to be recompiled
                    173:        if you wish to link new programs against those libraries.
