6 + 20161013:
7 +        Sync ZFS code with Illuminos/FreeBSD 9.2. Added support for
8 +        feature flags, pool version 5000. This also includes some
9 +        bug fixes and performance optimizations.
10 +
11 + 20160925:
12 +        Import NetBSD vis(3) and unvis(3) as well as mtree.
13 +
14 +        one-true-awk 20121220
15 +
16 +        inetd now honors kern.ipc.somaxconn value.
17 +
18 +        netmap synced with FreeBSD 9.2
19 +
20 +        linuxolator now has dtrace probes.
21 +
22 +        bsdgrep now correctly handles -m to exclude only one file.
23 +
24 +        UFS file systems can now be resized in read-write mode due to the new
25 +        write suspension feature.
26 +
27 +        Basic support added for Intel Raid Recover Technology.
28 +
29 +        GMIRROR & GRAID3 now mark volumes clean on shutdown earlier to help with ZFS issues.
30 +
31 +        Highpoint hpt27xx now in GENERIC kernel.
32 +
33 + 20160923:
34 +        Security update for OpenSSL
35 +
36 +        A malicious client can send an excessively large OCSP Status Request extension.
37 +        If that client continually requests renegotiation, sending a large OCSP Status
38 +        Request extension each time, then there will be unbounded memory growth on the
39 +        server. [CVE-2016-6304]
40 +
41 +        An overflow can occur in MDC2_Update() either if called directly or through
42 +        the EVP_DigestUpdate() function using MDC2. If an attacker is able to supply
43 +        very large amounts of input data after a previous call to EVP_EncryptUpdate()
44 +        with a partial block then a length check can overflow resulting in a heap
45 +        corruption. [CVE-2016-6303]
46 +
47 +        If a server uses SHA512 for TLS session ticket HMAC it is vulnerable to a
48 +        DoS attack where a malformed ticket will result in an OOB read which will
49 +        ultimately crash. [CVE-2016-6302]
50 +
51 +        The function BN_bn2dec() does not check the return value of BN_div_word().
52 +        This can cause an OOB write if an application uses this function with an
53 +        overly large BIGNUM. This could be a problem if an overly large certificate
54 +        or CRL is printed out from an untrusted source. TLS is not affected because
55 +        record limits will reject an oversized certificate before it is parsed.
56 +        [CVE-2016-2182]
57 +
58 +        The function TS_OBJ_print_bio() misuses OBJ_obj2txt(): the return value is
59 +        the total length the OID text representation would use and not the amount
60 +        of data written. This will result in OOB reads when large OIDs are presented.
61 +        [CVE-2016-2180]
62 +
63 +        Some calculations of limits in OpenSSL have used undefined pointer arithmetic.
64 +        This could cause problems with some malloc implementations. [CVE-2016-2177]
65 +
66 +        Operations in the DSA signing algorithm should run in constant time in order to
67 +        avoid side channel attacks. A flaw in the OpenSSL DSA implementation means that
68 +        a non-constant time codepath is followed for certain operations. [CVE-2016-2178]
69 +
70 +        In a DTLS connection where handshake messages are delivered out-of-order those
71 +        messages that OpenSSL is not yet ready to process will be buffered for later
72 +        use. Under certain circumstances, a flaw in the logic means that those messages
73 +        do not get removed from the buffer even though the handshake has been completed.
74 +        An attacker could force up to approx. 15 messages to remain in the buffer when
75 +        they are no longer required. These messages will be cleared when the DTLS
76 +        connection is closed. The default maximum size for a message is 100k. Therefore
77 +        the attacker could force an additional 1500k to be consumed per connection.
78 +        [CVE-2016-2179]
79 +
80 +        A flaw in the DTLS replay attack protection mechanism means that records that
81 +        arrive for future epochs update the replay protection "window" before the MAC
82 +        for the record has been validated. This could be exploited by an attacker by
83 +        sending a record for the next epoch (which does not have to decrypt or have a
84 +        valid MAC), with a very large sequence number. This means that all subsequent
85 +        legitimate packets are dropped causing a denial of service for a specific
86 +        DTLS connection. [CVE-2016-2181]
87 +
88 +        In OpenSSL 1.0.2 and earlier some missing message length checks can result in
89 +        OOB reads of up to 2 bytes beyond an allocated buffer. There is a theoretical
90 +        DoS risk but this has not been observed in practice on common platforms.
91 +        [CVE-2016-6306]
92 +
93 + 20160918:
94 +        With the addition of auditdistd(8), a new auditdistd user is now
95 +        depended on during installworld.  "mergemaster -p" can be used to add
96 +        the user prior to installworld.
97 +
98 +        The VFS KBI was changed with the merge of several nullfs
99 +        optimizations and fixes.  All filesystem modules must be
100 +        recompiled.
101 +
102 + 20160916:
103 +        The random(4) support for the VIA hardware random number
104 +        generator (`PADLOCK') is no longer enabled unconditionally.
105 +        Add the PADLOCK_RNG option in the custom kernel config if
106 +        needed.  The GENERIC kernels on i386 and amd64 do include the
107 +        option, so the change only affects the custom kernel
108 +        configurations.
109 +
110 +        A new version of ZFS (pool version 5000) has been merged.
111 +        Starting with this version the old system of ZFS pool versioning
112 +        is superseded by "feature flags". This concept enables forward
113 +        compatibility against certain future changes in functionality of ZFS
114 +        pools. The first two read-only compatible "feature flags" for ZFS
115 +        pools are "com.delphix:async_destroy" and "com.delphix:empty_bpobj".
116 +        For more information read the new zpool-features(7) manual page.
117 +        Please refer to the "ZFS notes" section of this file for information
118 +        on upgrading boot ZFS pools.
119 +
120 + 20160906:
121 +        Add support for the MosChip MCS9904 four serial ports
122 +        controller.
123 +
124 +        Add support for walltimestamp in DTrace.
125 +
126 +        Various gdb improvments.
127 +
128 +        ZFS
129 +        Import the zio nop-write improvement from Illumos. To reduce I/O,
130 +        nop-write omits overwriting data if the checksum (cryptographically
131 +        secure) of new data matches the checksum of existing data.
132 +        It also saves space if snapshots are in use.
133 +
134 +        It currently works only on datasets with enabled compression, disabled
135 +        deduplication and sha256 checksums.
136 +
137 +        Add loader(8) tunable to enable/disable nopwrite functionality:
138 +        vfs.zfs.nopwrite_enabled
139 +
140 +        Introduce a new dataset aclmode setting "restricted" to protect ACL's
141 +        being destroyed or corrupted by a drive-by chmod.
142 +
143 +        New loader-only tunables:
144 +        vfs.zfs.sync_pass_deferred_free
145 +        vfs.zfs.sync_pass_dont_compress
146 +        vfs.zfs.sync_pass_rewrite
147 +
148 +        chkgrp(8) add support for q flag
149 +
150 +        Fix problem with the Samsung 840 PRO series SSD detection.
151 +        The device reports support for SATA Asynchronous Notification in its
152 +        IDENTIFY data, but returns error on attempt to enable that feature.
153 +        Make SATA XPT of CAM only report these errors, but not fail the device.
154 +
155 + 20160905:
156 +        Add a resource limit for the total number of kqueues
157 +        available to the user. Kqueue now saves the ucred of the
158 +        allocating thread, to correctly decrement the counter on close.
159 +        Based on FreeBSD SVN 256849
160 +
161 +        Import netcat from OpenBSD 5.2
162 +
163 + 20160904:
164 +        Introduced experimental TCP sysctls starting with
165 +        net.inet.tcp.experimental.initcwnd10
166 +
167 + 20160814:
168 +        switched default desktop port to midnightbsd-desktop. This gives us flexibility to change it
169 +        in the release after the fact.
170 +
171 +        tzdata 2016a
172 +
173 + 20160811:
174 +        libdispatch 210
175 +
176 +        Added quirks for several models of SSDs to enable advanced format/4k mode. List includes
177 +        Samsung 830, 840, 850 and 750 series, Intel x25 and a few Toshiba models. Also
178 +        added WD Red drives.
179 +
180 +        Updated list of pci device vendors.
181 +
182 +        Updated list of usb devices.
183 +
184 + 20160807:
185 +        Implement several changes to libmport to fix some memory corruption issues.
186 +
187 + 20160806:
188 +        sqlite3 3.13.0
189 +
190 + 20160805:
191 +        Merged fixes for libmport that improve error handling when installing packages. Also
192 +        support mkdir -p like behavior for plist entries.
193 +
194 + 20160531:
195 +        Fix four security issues with MidnightBSD.
196 +
197 +        The implementation of TIOCGSERIAL ioctl(2) does not clear the output
198 +        struct before sending to userland in the linux emulation layer.
199 +
200 +        The compat 43 stat(2) system call exposes kernel stack to userland.
201 +
202 +        libarchive - CVE-2015-2304 and CVE-2013-0211 fix issues with
203 +        cpio directory traversal and an integer signedness error in the archive
204 +        write zip data routine.
205 +
206 +
207 + 20160528:
208 +        Fixed minor issues with mined(1) and msearch(1).
209 +
210 + 20160526:
211 +        Add support for Ivybridge and Haswell Intel CPUs to hwpmc(4).
212 +
213 +        Fix libpmc(3) build with clang compiler.
214 +
215 + 20160519:
216 +        Kernel Security updates
217 +
218 +        atkbd(4) - Incorrect signedness comparison in the ioctl(2) handler allows a malicious
219 +        local user to overwrite a portion of the kernel memory.
220 +
221 +        Incorrect argument handling in sendmsg(2)
222 +
223 +        Incorrect argument handling in the socket code allows malicious local
224 +        user to overwrite large portion of the kernel memory.
225 +
226 + 20160505:
227 +        OpenSSL security patch
228 +
229 +        The padding check in AES-NI CBC MAC was rewritten to be in constant time
230 +        by making sure that always the same bytes are read and compared against
231 +        either the MAC or padding bytes. But it no longer checked that there was
232 +        enough data to have both the MAC and padding bytes. [CVE-2016-2107]
233 +
234 +        An overflow can occur in the EVP_EncodeUpdate() function which is used for
235 +        Base64 encoding of binary data. [CVE-2016-2105]
236 +
237 +        An overflow can occur in the EVP_EncryptUpdate() function, however it is
238 +        believed that there can be no overflows in internal code due to this problem.
239 +        [CVE-2016-2106]
240 +
241 +        When ASN.1 data is read from a BIO using functions such as d2i_CMS_bio()
242 +        a short invalid encoding can casuse allocation of large amounts of memory
243 +        potentially consuming excessive resources or exhausting memory.
244 +        [CVE-2016-2109]
245 +
246 + 20160412:
247 +        0.8 stable branch created. Continue development as 0.9.
248 +
249 +        Fix several issues with wait6 system call addition.
250 +
251 + 20160409:
252 +        libmport now supports two new plist formats:
253 +        @(root,wheel,4775) myfile
254 +        @dir(root,wheel,775) mydir
255 +
256 +        On delete, absoluate paths are now handled properly.
257 +
258 + 20160317:
259 +        OpenSSH doesn't have the luck of the Irish.
260 +
261 +        Fix a security issue with OpenSSH X11 forwarding that can allow an attacker
262 +        run shell commands on the call to xauth.
263 +
264 +        Incorrect argument validation in sysarch(2)
265 +
266 +        A special combination of sysarch(2) arguments, specify a request to
267 +        uninstall a set of descriptors from the LDT.  The start descriptor
268 +        is cleared and the number of descriptors are provided.  Due to invalid
269 +        use of a signed intermediate value in the bounds checking during argument
270 +        validity verification, unbound zero'ing of the process LDT and adjacent
271 +        memory can be initiated from usermode.
272 +
273 +        Patch obtained from FreeBSD.
274 +
275 + 20160229:
276 +        top now displays information on ZFS arc cache.
277 +
278 + 20160228:
279 +        llvm + clang 3.3 is now the default compiler in MidnightBSD.
280 +
281 + 20160222:
282 +        Introduce pipe2 to linux emulation layer.
283 +
284 + 20160114:
285 +        OpenSSL
286 +
287 +        The signature verification routines will crash with a NULL pointer dereference
288 +        if presented with an ASN.1 signature using the RSA PSS algorithm and absent
289 +        mask generation function parameter. [CVE-2015-3194]
290 +
291 +        When presented with a malformed X509_ATTRIBUTE structure, OpenSSL will leak
292 +        memory. [CVE-2015-3195]
293 +
294 +        If PSK identity hints are received by a multi-threaded client then the values
295 +        are incorrectly updated in the parent SSL_CTX structure.  [CVE-2015-3196]
296 +
297 +        Fix security on bsnmpd configuration file during installation.
298 +
299 +        TCP MD5 signature denial of service
300 +
301 +        A programming error in processing a TCP connection with both TCP_MD5SIG
302 +        and TCP_NOOPT socket options may lead to kernel crash.
303 +
304 +        SCTP
305 +
306 +        A lack of proper input checks in the ICMPv6 processing in the SCTP stack
307 +        can lead to either a failed kernel assertion or to a NULL pointer
308 +        dereference.  In either case, a kernel panic will follow.
309 +
310 + 20160102:
311 +        Happy New Year
312 +
313 + 20151101:
314 +        Increase kern.ipc.somaxconn default to 256.
315 +
316 + 20151017:
317 +        Add initial statistics api to libmport and a driver to print
318 +        it in mport(1).
319 +
320 + 20151002:
321 +        Revised rpcbind(8) patch to fix issues with NIS
322 +
323   20150930:
324          In rpcbind(8), netbuf structures are copied directly, which would result in
325          two netbuf structures that reference to one shared address buffer.  When one
