Added changelow for noquiet and inet6glue

1 ==============================================================================
2 CHANGES to fetch-crl - the Certificate Revocation List retrieval tool
3 ==============================================================================
4 The fetch-crl utility will retrieve certificate revocation lists (CRLs) for
5 a set of installed trust anchors, based on crl_url files or IGTF-style info
6 files. It will install these for use with OpenSSL, NSS or third-party tools.
7
8 Changes in 3.0.10-1
9 ----------------------
10 * Added a "noquiet" option in the configuration file that will override
11 the default single "-q" option in the cro-job that is shipped with
12 the fetch-crl3 init scripts (feature request by Ryan Taylor)
13 * Added option "--inet6glue" and "inet6glue" config setting to load
14 the Net::INET6Glue perl module (if its available) to use IPv6
15 connections in LWP to download CRLs
16
17 Changes in 3.0.8-1
18 ----------------------
19 * Trust anchor name inferrence based on retrieved-CRL added as option (at cost
20 of retrieving CRL even if there is no accompanying trust anchor found later)
21 Option is disabled by default, but can be enabled by using @HASH@ in the
22 ca-template name list. (feature request by Rob van der Wal, SARA, NL)
23
24 Changes in 3.0.7-1
25 ----------------------
26 * CRL modofication time heuristic inadvertently modified file name templates
27 (solves issue kindly reported by Elan Ruusamae)
28 * Expanded representation of tokenisation characters in strings to work
29 around bug in file(1) (rhbz#699546, works around RedHat Bugzilla 699548)
30
31 Changes in 3.0.6-1
32 ----------------------
33 * Response parsing disabled to suppress superfluous warning on unexpected
34 UTF-8 respons when retrieving a CRL (solves RedHat Bugzilla 688902)
35
36 Changes in 3.0.5-1
37 ----------------------
38 * CRLs for multiple similarly-named trust anchors might not all be downloaded.
39 This is fixed in this release.
40 * Spurious "restoreLogMode" internal errors are no longer raised
41
42 Changes in 3.0.4-1
43 ----------------------
44 * Add support for directory based drop-in configuration in /etc/fetch-crl.d/
45 * Only use cached CRL contents if the nextUpdate time of the cached CRL is
46 still in the future. This will ensure that a new download is attempted
47 each and everytime for CRLs that have already expired.
48
49 Changes in 3.0.3-1
50 ----------------------
51 * Clean up of man page format macro PU (reported by Mattias Ellert)
52
53 Changes in 3.0.2-1
54 ----------------------
55 * Clean up of man page format macro PU (reported by Mattias Ellert)
56
57 Changes in 3.0.1-1
58 ----------------------
59 * hunts through more places to find the latest successful CRL download to
60 set the latest local modification time for a CRL
61 (resolves a comparison error in case output and infodir are unset)
62
63 Changes in 3.0.0-0.RC4
64 ----------------------
65 * the config file name has changed to fetch-crl.conf, although a
66 fetch-crl.cnf file will also be used when present
67 * symlinked meta-data files can be ignored with the --nosymlinks option
68 (or nosymlinks in the configuration file). This allows fetch-crl to be
69 used effectively with new-format IGTF distribution before 1.37
70 * infinite loop for non-indexed CA file names fixed
71
72 Changes in fetch-crl 3.0
73 ------------------------
74 * fetch-crl 3.0 is a complete re-write, and shares no code with the 1.x and
75 2.x series utility of the same name, although the function and some of
76 the syntax is obviously the same
77
78 * support for multiple output formats: OpenSSL 1 in dual-hash mode, specific
79 DER and PEM outputs, and NSS databases
80 * support for multiple CRLs for a single CA, allowing more than one CA with
81 the same subject name but different CLRs. Review your client software to see
82 if and how these CRLs are used.
83 * stateful retrieval helps reduce bandwidth usage by caching the CRLs locally
84 and respecting the Cache Control headers sent by the web server hosting the
85 CRL. This can reduce the number of downloads
86 * support for HEAD-only requests when state preservation is used (initially
87 only retrieve HTTP headers, and only if the CRL actually changed to a full
88 download)
89 * support for more CRL retrieval protocols (file:// and ftp://)
90 * ability to try site-local URLs first, before relying on the URLs shipped with
91 the trust anchor. This allows building an explicit local caching (web) server.
92 * ability to specify additional URLs to try in case the URLs shipped with the
93 trust anchor were not responsive. This allows for automatic fall-back to
94 (local or global) mirror services for CRL downloads
95 * warnings and errors can be suppressed on a per-trust anchor basis, to allow
96 silencing for particularly unstable trust anchors
97 * aging tolerance (the delay time before errors are generated in case downloads
98 consistently fail) can be configured on a per-trust anchor basis
99 * parallel downloading for multiple trust anchors
100 * minimized use of temporary files in the file system (now limited to the
101 invocation of OpenSSL only, and only for brief periods of time)
102 * dependencies on wget, lynx and other unix utilities have been removed
103 * explicit web proxy support (using LWP http proxies)
104 * completely re-written in perl, with some (hopefully minimal) dependencies:
105 LWP, Sys::Syslog, POSIX. And Data::Dumper (when debugging is enabled),
106 and IO::Select (if parallel downloads are enabled).
107
108 Differences with respect to the previous versions
109
110 * when downloading CRLs via https, the server certificate is not checked,
111 neither for the correct DNS name nor for being issued by a valid CA. Since
112 the CRL in itself is signed, this is not a security vulnerability. If
113 stricter checking is anyway desired, and the Crypt::SSLeay perl module has
114 been installed, set the HTTPS_CA_FILE environment variable before invoking
115 fetch-crl -- but keep in mind that the DNS name verification is limited
116 and will (incorrectly) reject DNS names if these are listed only in the
117 subjectAlternativeName of the server certificate
118 * Existing files with a name that matches a CRL target name are overwritten,
119 even if they did not originally contain CRL data. In v2 this was configurable
120 via the FORCE_OVERWRITE configuration setting. In version 3, files are
121 overwritten by default, and this can no longer be configured.
122 * fetch-crl3 will no longer check CA certificates for consistency or validity
123 by themselves, only retrieved CRLs are verified
124
125 Downsides of the new version
126
127 * it requires perl5 to be installed (tested with perl 5.8.0 and higher) with
128 libwww-perl, whereas version 2 only required a traditional Bourne shell
129 * requires a version of OpenSSL (0.9.5a or better) to be installed. Needs
130 OpenSSL 1.0.0 (at least beta5) for dual-hash support.
131 * when using parallel downloads, it can only run on pure-POSIX systems
132 * parallelism in combination with the NSS database output format is not tested
133 * Even when only the NSS database output format has been selected, OpenSSL is
134 still needed for verification and processing
135
136
137 ==============================================================================
138
139 The change log below applies to the 1.x and 2.x series fetch-crl and is
140 included for historical purposes only. Fetch-crl3, with which this
141 changes file is being shipped, is a complete re-write of the utility.
142 Although a lot of backwards compatibility has been preserves, there have
143 been significant changes and the information below should NOT be used
144 to infer any behaviour of fetch-crl3.
145
146 Fetch-crl 1.x and 2.x were released under the EU DataGrid License.
147
148 Changes in version EGP 2.8.5
149 ----------------------------
150 (2010.06.03)
151
152 * fetch-crl was occasionally leaving behind {hash}.r0.XXXXXX.r0 files
153 This has been fixed in this release (patch thanks to Jason Smith, BNL)
154 * man page was not compliant to Debian guidelines, this has been fixed
155 (patch thanks to Mattias Ellert, Uppsala University)
156
157 Changes in version EGP 2.8.4
158 ----------------------------
159 (2010.04.04)
160
161 * Fixes error when randomWait is not set [RH Bug 579488]
162
163 Changes in version EGP 2.8.3
164 ----------------------------
165 (2010.03.28)
166
167 * Preserve SELinux context for CRL files if SElinux status program exists
168 and selinux is enabled (RH bug 577403)
169 * Fix argument parsing on syslog facility specification (RH bug 577387)
170 * Increase granularity of the RandomWait and allow for 0 in -r option
171
172 Changes in version EGP 2.8.2
173 ----------------------------
174 (2010.03.03)
175
176 * Improved support for multiple CRL URLs by downloading until a success
177 is achieved, instead of downloading all of them
178 * Imported randomwait patch from Steve Traylen
179
180 Changes in version EGP 2.8.1
181 ----------------------------
182 (2010.01.26)
183
184 * The installed CRL file is re-checked for validity to catch file system
185 errors and local disk corruption. When possible, it will try to restore
186 a backup copy. Failures are not subject to aging tolerance.
187
188 Changes in version EGP 2.8.0
189 ----------------------------
190 (2009.09.22)
191
192 * The RPM packaging has been overhauled and is now sufficiently conformant
193 to EPEL and FedoraProject guidelines.
194 * New init scripts and a cron job entry have been added to allow management
195 of fetch-crl via the chkconfig mechanism
196
197 These changes were contributed by Steve Traylen (CERN, Geneva, CH).
198
199 Changes in version EGP 2.7.0
200 ----------------------------
201 (2009.01.25)
202
203 * Warnings and errors are now counted. If there are errors in the download
204 or verification process for one or more CRLs, the exit status will be 1;
205 if there are errors in the local setup or in the script invocation, the
206 exit status will be 2.
207 * The installed CRLs no longer have the textual representation of the CRL,
208 but only the PEM data blob, thus reducing IO and memory requirements.
209 * the CRL aging threshold is now set by default to 24 hours. The previous
210 default was 0. The CRL aging threshold is set in the config file using
211 CRL_AGING_THRESHOLD=<xx>, or with the "-a" command-line argument.
212 * Default network timeouts reduced to 10 seconds (was 30) and retries to 2
213 * Added caching and conditional downloading. When CACHEDIR is set, the
214 original downloads are preserved and wget timestamping mode enabled.
215 When the content did not change, only the timestamp on the installed
216 CRL is updated. If SLOPPYCRLHASHES is set, the has is calculated based
217 on the name of the crl_url file, otherwise it is taken from the CRL itself.
218 - The CACHEDIR must be exclusively writable by the user running fetch-crl
219 - Setting CACHEDIR significantly reduced the bandwidth used by fetch-crl
220 * Added RESETPATHMODE setting in sysconfig. It defines whether or not to
221 set re-set $PATH to "/bin:/usr/bin" before start. The search for OpenSSL
222 may be done based on the old path.
223 yes=always replace; searchopenssl=search for openssl first and then reset;
224 no=keep original path, whatever that me be (may be empty if called from cron)
225 Default="yes". This replaces the hard-coded path in the tool!
226 * Hidden "FORCE_OVERWRITE" option now has a regular name. This is backwards-
227 compatible. Set FORCE_OVERWRITE=yes if you want files overwritten that
228 have a CRL-like name and ought to have CRL content, but currently do not.
229 * Addresses gLite Savannah bugs 28418 and 29559. Bug 27023 is partially
230 addressed. Bug 20062 can be remedied with WGET_OPTS arguments.
231 Addresses OSG ticket 4673.
232
233 Changes in version EGP 2.6.6
234 ----------------------------
235 (2007.09.16)
236 (version 2.5.5 is invalid and was not publicly released)
237
238 * Added obscure configuration parameter to allow overwriting of
239 arbitrary data files with a downloaded CRL (on request of
240 CERN, see https://savannah.cern.ch/bugs/index.php?29559)
241
242 Changes in version EGP 2.6.4
243 ----------------------------
244 (2007.08.15)
245
246 * Expired CA issuer certificate now gives a warning instead of an error
247 with the full verification result message
248 * additional logfile output target can be selected via the configuration file
249 * CRL aging threshold documented in manual page. Errors will now also be
250 generated in the CRL download failed consistently and the current CRL
251 has already expired
252
253 Changes in version EGP 2.6.3
254 ----------------------------
255 (2006.11.13)
256
257 * cron job example: fetch-crl invocation syntax error corrected
258
259 Changes in version EGP 2.6.2
260 ----------------------------
261 (2006.10.27)
262
263 * fixed bug: older wget versions do not recognise --no-check-certificate
264
265 Changes in version EGP 2.6.1
266 ----------------------------
267 (2006.10.25)
268
269 * fixed local timezone vs UTC error in LastUpdate CRL validation comparison
270 * fixed time comparison is the one-hour LastUpdate/download tolerance
271 (both fixes thanks to Alain Roy)
272 * added support for directory names containing whitespace
273 * added support for syslog reporting (via -f option or SYSLOGFACILITY directive)
274 * SERVERCERTCHECK=no is now the default. It can be reset via the configuration
275 file, or using the "--check-server-certificate" commandline option
276 * the main configuration file location (formerly fixed to be
277 /etc/sysconfig/fetch-crl) can now be set via the variable $FETCH_CRL_SYSCONFIG
278 * logfile format timestamp and tag have been normalised
279
280 Changes in version EGP 2.6
281 --------------------------
282 (2006.05.20)
283
284 * if the current local CRL has a lastUpdate time in the future, and the
285 newly downloaded CRL is older that the current one, allow the installation
286 of the newly downloaded CRL and issue a warning.
287 * added non-suppressable warning in case the newly downloaded CRL has a
288 lastUpdate time in the future, but install that CRL anyway (as the local
289 clock might have been wrong).
290
291 Changes in version EGP 2.5
292 --------------------------
293 (2006.01.16)
294
295 * added additional configuration arguments and configuration variables
296 to skip the server certificate check in wget
297 (to support https:// URLs where the server is authenticated with
298 a certificate that is not part of it's own trusted domain, such as
299 the KISTI URL)
300
301 Changes in version EGP 2.4
302 --------------------------
303 (2005.11.15)
304
305 * for those platforms that support the stat(1) command, and in case the
306 .crl_url file is named after the hash of the crl subject name to download,
307 error eporting for individual download errors can be suppressed for
308 a configurable amount of time as set via the "-a" option (unit: hours).
309
310 Changes in version EGP 2.3
311 --------------------------
312 (2005.11.05)
313
314 * do not replace recent CRLs with ones that have an older lastUpdate
315 timestamp (prevents ARP/DNS DoS attacks)
316
317 Changes in version EGP 2.2
318 --------------------------
319 (2005.10.27)
320
321 * secure http download by wget recognise the CAs in the trusted directory.
322 solves the issue described in the LCG bug tracking system
323 https://savannah.cern.ch/bugs/index.php?func=detailitem&item_id=12182
324
325 Changes in version EGP 2.1
326 --------------------------
327 (2005.08.12)
328 * specifically look for the most recent version of OpenSSL. The
329 one in GLOBUS_LOCATION (which used to take precedence in the
330 previous releases) is outdated in many cases and caused
331 troubles on the LCG production systems in validating v2 CRLs
332 * added manual page fetch-crl(8)
333
334 Changes in version EGP 2.0
335 --------------------------
336 (2005.02.28)
337 * name of the installed script changed to "fetch-crl"
338 * the cronjob script is no longer installed by default, but supplied
339 as an example in the %doc directory
340 * RPM is now relocatable (default install in /usr)
341 * READMA and CHANGES file now inclued in %doc tree
342 * make install now installs
343 * version increased to 2.0
344
345 Changes in version EGP 1.9
346 --------------------------
347 (2005.02.24)
348 * the content of the final target CRL file is now checked for
349 containing a valid CRL if it already exists. If it does not
350 contain a CRL, an error is displayed and the file left untouched
351 So making the final ".r0" file in ${outdir} a link to something else
352 will not work, preventing an escalation in the final stage.
353
354 Changes in version EGP 1.8
355 --------------------------
356 (changes from Fabio's version 1.7, 2005.02.24)
357
358 * All temporary files (the initial CRL download using wget
359 and the PEM-converted version of that file) are now created using
360 mktemp
361 * the RetrieveFileByURL function will not overwrite files that
362 have any data in them
363 * Note that the script can be run by a non-priviledged user, but
364 that the output directory must be made writable by that user
365 in an out-of-band way.
366
