# Line 1 | Line 1
1   Updating Information for MidnightBSD users.
2  
3 + 20160229:
4 +        top now displays information on ZFS arc cache.
5 +
6 + 20160228:
7 +        llvm + clang 3.3 is now the default compiler in MidnightBSD.
8 +
9 + 20160222:
10 +        Introduce pipe2 to linux emulation layer.
11 +
12 + 20160114:
13 +        OpenSSL
14 +
15 +        The signature verification routines will crash with a NULL pointer dereference
16 +        if presented with an ASN.1 signature using the RSA PSS algorithm and absent
17 +        mask generation function parameter. [CVE-2015-3194]
18 +
19 +        When presented with a malformed X509_ATTRIBUTE structure, OpenSSL will leak
20 +        memory. [CVE-2015-3195]
21 +
22 +        If PSK identity hints are received by a multi-threaded client then the values
23 +        are incorrectly updated in the parent SSL_CTX structure.  [CVE-2015-3196]
24 +
25 +        Fix security on bsnmpd configuration file during installation.
26 +
27 +        TCP MD5 signature denial of service
28 +
29 +        A programming error in processing a TCP connection with both TCP_MD5SIG
30 +        and TCP_NOOPT socket options may lead to kernel crash.
31 +
32 +        SCTP
33 +
34 +        A lack of proper input checks in the ICMPv6 processing in the SCTP stack
35 +        can lead to either a failed kernel assertion or to a NULL pointer
36 +        dereference.  In either case, a kernel panic will follow.
37 +
38 + 20160102:
39 +        Happy New Year
40 +
41 + 20151101:
42 +        Increase kern.ipc.somaxconn default to 256.
43 +
44 + 20151017:
45 +        Add initial statistics api to libmport and a driver to print
46 +        it in mport(1).
47 +
48 + 20151002:
49 +        Revised rpcbind(8) patch to fix issues with NIS
50 +
51 + 20150930:
52 +        In rpcbind(8), netbuf structures are copied directly, which would result in
53 +        two netbuf structures that reference to one shared address buffer.  When one
54 +        of the two netbuf structures is freed, access to the other netbuf structure
55 +        would result in an undefined result that may crash the rpcbind(8) daemon.
56 +
57 + 20150926:
58 +        libmport now supports @preexec, @postexec, @preunexec and @postunexec
59 +        to replace @exec and @unexec.  
60 +
61 +        pre exec runs afer pre-install scripts but before actual installation
62 +
63 +        post exec runs after install but before post install scripts and
64 +        pkg message.
65 +
66 +        pre unexec runs before pre uninstall scripts
67 +
68 +        post unexec runs before de-install scripts and after file removal.
69 +
70 + 20150917:
71 +        Fix kqueue write events for files > 2GB
72 +
73 + 20150825:
74 +        kernel:
75 +        fix a security issue on amd64 where the GS segment CPU register can be changed via
76 +        userland value in kernel mode by using an IRET with #SS or #NP exceptions.
77 +
78 +        openssh:
79 +        A programming error in the privileged monitor process of the sshd(8)
80 +        service may allow the username of an already-authenticated user to be
81 +        overwritten by the unprivileged child process.
82 +
83 +        A use-after-free error in the privileged monitor process of he sshd(8)
84 +        service may be deterministically triggered by the actions of a
85 +        compromised unprivileged child process.
86 +
87 +        A use-after-free error in the session multiplexing code in the sshd(8)
88 +        service may result in unintended termination of the connection.
89 +
90 + 20150818:
91 +        expat security fix
92 +
93 + 20150815:
94 +        libc changes:
95 +        setmode(3) now returns errno consistently on error.
96 +        libc will compile without error using clang
97 +
98 + 20150814:
99 +        wait6 system call added.
100 +
101 +        date(1) now handles non numeric numbers passed to -r
102 +        like GNU coreutils for improved compatibility.
103 +
104 + 20150811:
105 +        ata(4) AMD Hudson2 SATA controller support.
106 +        Intel lynxpoint SATA.
107 +
108 +        Fix some const warnings when building several device drivers
109 +        with llvm/clang.
110 +
111 +        Sync cas(4) with FreeBSD 9-stable.
112 +
113 +        Fix some minor issues with ath(4).
114 +
115 + 20150809:
116 +        xz 5.0.8
117 +
118 + 20150808:
119 +        libmport now logs installation and removal of packages to syslog.
120 +
121 + 20150805:
122 +        routed - fix a potential security issue where traffic from outside
123 +        the network can disrupt routing.
124 +
125 +        bsd patch - fix a bug with ed(1) scripts allowing unsanitized input
126 +        to run.
127 +
128 + 20150802:
129 +        jansson 2.7 library added. (libjansson is a JSON library in C)
130 +
131 + 20150728:
132 +        Heimdal 1.5.2 (kerberos implementation)
133 +
134 +        OpenSSL 1.0.1o
135 +
136 +        cpucontrol(8) now supports VIA CPUs. Synced with FreeBSD 9.2.
137 +
138 +        TCP Resassemly resource exhaustion bug:
139 +        There is a mistake with the introduction of VNET, which converted the
140 +        global limit on the number of segments that could belong to reassembly
141 +        queues into a per-VNET limit.  Because mbufs are allocated from a
142 +        global pool, in the presence of a sufficient number of VNETs, the
143 +        total number of mbufs attached to reassembly queues can grow to the
144 +        total number of mbufs in the system, at which point all network
145 +        traffic would cease.
146 +        Obtained from: FreeBSD 8
147 +
148 +        OpenSSH
149 +
150 +        Fix two security vulnerabilities:
151 +        OpenSSH clients does not correctly verify DNS SSHFP records when a server
152 +        offers a certificate. [CVE-2014-2653]
153 +
154 +        OpenSSH servers which are configured to allow password authentication
155 +        using PAM (default) would allow many password attempts. A bug allows
156 +        MaxAuthTries to be bypassed. [CVE-2015-5600]
157 +
158 +
159 +        Switch to bsdpatch (from FreeBSD & OpenBSD)
160 +
161 + 20150726:
162 +        BSD Sort updated
163 +
164 +        sqlite 3.8.10.2
165 +
166 + 20150725:
167 +        Import reallocarray from OpenBSD's libc.  
168 +
169 +        The reallocarray() function is similar to realloc() except it operates on
170 +        nmemb members of size size and checks for integer overflow in the
171 +        calculation nmemb * size.
172 +
173 + 20150722:
174 +        Fix a bug where TCP connections transitioning to LAST_ACK
175 +        state can get stuck. This can result in a denial of service.
176 +
177 + 20150715:
178 +        libmport now supports @shell and @sample in plists. This means that
179 +        a shell port can automatically add an entry to /etc/shells and remove
180 +        it upon uninstallation. For sample files, a copy is made without the
181 +        .sample extension if one does not exist and it is removed automatically
182 +        only if the md5 hash of the two files is the same.
183 +
184 + 20150709:
185 +        flex 2.5.39
186 +
187 + 20150702:
188 +        ZFS in MidnightBSD now supports lz4 compression. You can enable it
189 +        with zfs set compression=lz4 pool/path.
190 +
191 +        Verify it's working with
192 +        zfs get compressratio pool/path
193 +        du -h -s *
194 +
195 +        Note you must write new data when turning on compression to see
196 +        changes. Existing files are not compressed.
197 +
198 +        Note: While we used the same basic implementation of lz4 that
199 +        FreeBSD and OpenZFS uses, we did not yet implement features support
200 +        and the zfs version still reports 28. This may come in a future update
201 +        to ZFS.
202 +
203 + 20150621:
204 +        libmport now automatically stops services when deleting packages.
205 +
206 +        The package must have installed an rc.d script in /usr/local/etc
207 +        for this to work. This is equivalent to running service <name> onestop
208 +
209 + 20150618:
210 +        Sendmail
211 +
212 +        With the recent changes to OpenSSL to block 512 bit certificates,
213 +        sendmail can't connect with TLS to some servers.
214 +
215 +        Increase the default size to 1024 bit for client connections to
216 +        match the server configuration.
217 +
218 +        ZFS
219 +
220 +        Added ZFS TRIM support which is enabled by default. To disable
221 +        ZFS TRIM support set vfs.zfs.trim.enabled=0 in loader.conf.
222 +
223 +        Creating new ZFS pools and adding new devices to existing pools
224 +        first performs a full device level TRIM which can take a significant
225 +        amount of time. The sysctl vfs.zfs.vdev.trim_on_init can be set to 0
226 +        to disable this behaviour.
227 +
228 +        ZFS TRIM requires the underlying device support BIO_DELETE which
229 +        is currently provided by methods such as ATA TRIM and SCSI UNMAP
230 +        via CAM, which are typically supported by SSD's.
231 +
232 +        Stats for ZFS TRIM can be monitored by looking at the sysctl's
233 +        under kstat.zfs.misc.zio_trim.
234 +
235 +        rc.d
236 +
237 +        Reworked handling of cleanvar and FILESYSTEMS so that FILESYSTEMS
238 +        implies everything is mounted and ready to go.
239 +
240 +        Changed how ip6addressctl maps IPv6 on startup.
241 +
242 + 20150613:
243 +        tzdata 2015d
244 +
245 + 20150612:
246 +        OpenSSL 0.9.8zg
247 +
248 + 20150419:
249 +        MidnightBSD 0.6 stable branch created. Continue 0.7
250 +        development.
251 +
252 + 20150418:
253 +        sqlite 3.8.9
254 +
255 + 20150407:
256 +        Fix two security vulnerabilities:
257 +
258 +        The previous fix for IGMP had an overflow issue. This has been corrected.
259 +
260 +        ipv6: The Neighbor Discover Protocol allows a local router to advertise a
261 +        suggested Current Hop Limit value of a link, which will replace
262 +        Current Hop Limit on an interface connected to the link on the MidnightBSD
263 +        system.
264 +
265 + 20150319:
266 +        OpenSSL 0.9.8.zf
267 +
268 +        mksh R50e
269 +
270 +        Apple mDNSResponder 561.1.1
271 +
272   20150306:
273          Upgrade OpenSSL to 0.9.8ze
