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 3.0.15-1
9 ----------------------
10 * Fixed issues resulting in undefined attribute values to be returned for CRL
11
12 Changes in 3.0.14-1
13 ----------------------
14 * Requesting CRL retrieval for an empty trust anchor store is now a warning
15 and no longer an error
16
17 Changes in 3.0.13-1
18 ----------------------
19 * Supplied system init script for boot phase will not re-run inadvertently
20 * Add rcmode config option (added differentiated reporting and success-on-
21 solely-retrieval-errors)
22 * Add --define key=val command line argument to augment configuration data
23 * Setting FETCHCRL_OPTIONS in /etc/sysconfig/fetch-crl will add these
24 options to the commandline of fetch-crl on start from cron or at boot time
25 Setting FETCHCRL_BOOT_OPTIONS adds them to the boot init script only
26 (e.g. FETCHCRLBOOTOPTIONS="--define rcmode=differentiated")
27 and FETCHCRL_CRON_OPTIONS does the same only for the cron job script
28
29 Changes in 3.0.12-1
30 ----------------------
31 * PEM formatted CRLs now always include a final newline character (fix
32 provided by Harald Barth <haba@kth.se>)
33
34 Changes in 3.0.11-1
35 ----------------------
36 * Added reference to /etc/fetch-crl.d/ to the man page, used shortened URL
37 to full documentation in man page
38 * Added version information to help output and added -V option
39 * Added a dangerous clean-crl script to remove stale .r* files (beware!)
40
41 Changes in 3.0.10-1
42 ----------------------
43 * Added a "noquiet" option in the configuration file that will override
44 the default single "-q" option in the cro-job that is shipped with
45 the fetch-crl3 init scripts (feature request by Ryan Taylor)
46 * Added option "--inet6glue" and "inet6glue" config setting to load
47 the Net::INET6Glue perl module (if it is available) to use IPv6
48 connections in LWP to download CRLs
49
50 Changes in 3.0.8-1
51 ----------------------
52 * Trust anchor name inferrence based on retrieved-CRL added as option (at cost
53 of retrieving CRL even if there is no accompanying trust anchor found later)
54 Option is disabled by default, but can be enabled by using @HASH@ in the
55 ca-template name list. (feature request by Rob van der Wal, SARA, NL)
56
57 Changes in 3.0.7-1
58 ----------------------
59 * CRL modofication time heuristic inadvertently modified file name templates
60 (solves issue kindly reported by Elan Ruusamae)
61 * Expanded representation of tokenisation characters in strings to work
62 around bug in file(1) (rhbz#699546, works around RedHat Bugzilla 699548)
63
64 Changes in 3.0.6-1
65 ----------------------
66 * Response parsing disabled to suppress superfluous warning on unexpected
67 UTF-8 respons when retrieving a CRL (solves RedHat Bugzilla 688902)
68
69 Changes in 3.0.5-1
70 ----------------------
71 * CRLs for multiple similarly-named trust anchors might not all be downloaded.
72 This is fixed in this release.
73 * Spurious "restoreLogMode" internal errors are no longer raised
74
75 Changes in 3.0.4-1
76 ----------------------
77 * Add support for directory based drop-in configuration in /etc/fetch-crl.d/
78 * Only use cached CRL contents if the nextUpdate time of the cached CRL is
79 still in the future. This will ensure that a new download is attempted
80 each and everytime for CRLs that have already expired.
81
82 Changes in 3.0.3-1
83 ----------------------
84 * Clean up of man page format macro PU (reported by Mattias Ellert)
85
86 Changes in 3.0.2-1
87 ----------------------
88 * Clean up of man page format macro PU (reported by Mattias Ellert)
89
90 Changes in 3.0.1-1
91 ----------------------
92 * hunts through more places to find the latest successful CRL download to
93 set the latest local modification time for a CRL
94 (resolves a comparison error in case output and infodir are unset)
95
96 Changes in 3.0.0-0.RC4
97 ----------------------
98 * the config file name has changed to fetch-crl.conf, although a
99 fetch-crl.cnf file will also be used when present
100 * symlinked meta-data files can be ignored with the --nosymlinks option
101 (or nosymlinks in the configuration file). This allows fetch-crl to be
102 used effectively with new-format IGTF distribution before 1.37
103 * infinite loop for non-indexed CA file names fixed
104
105 Changes in fetch-crl 3.0
106 ------------------------
107 * fetch-crl 3.0 is a complete re-write, and shares no code with the 1.x and
108 2.x series utility of the same name, although the function and some of
109 the syntax is obviously the same
110
111 * support for multiple output formats: OpenSSL 1 in dual-hash mode, specific
112 DER and PEM outputs, and NSS databases
113 * support for multiple CRLs for a single CA, allowing more than one CA with
114 the same subject name but different CLRs. Review your client software to see
115 if and how these CRLs are used.
116 * stateful retrieval helps reduce bandwidth usage by caching the CRLs locally
117 and respecting the Cache Control headers sent by the web server hosting the
118 CRL. This can reduce the number of downloads
119 * support for HEAD-only requests when state preservation is used (initially
120 only retrieve HTTP headers, and only if the CRL actually changed to a full
121 download)
122 * support for more CRL retrieval protocols (file:// and ftp://)
123 * ability to try site-local URLs first, before relying on the URLs shipped with
124 the trust anchor. This allows building an explicit local caching (web) server.
125 * ability to specify additional URLs to try in case the URLs shipped with the
126 trust anchor were not responsive. This allows for automatic fall-back to
127 (local or global) mirror services for CRL downloads
128 * warnings and errors can be suppressed on a per-trust anchor basis, to allow
129 silencing for particularly unstable trust anchors
130 * aging tolerance (the delay time before errors are generated in case downloads
131 consistently fail) can be configured on a per-trust anchor basis
132 * parallel downloading for multiple trust anchors
133 * minimized use of temporary files in the file system (now limited to the
134 invocation of OpenSSL only, and only for brief periods of time)
135 * dependencies on wget, lynx and other unix utilities have been removed
136 * explicit web proxy support (using LWP http proxies)
137 * completely re-written in perl, with some (hopefully minimal) dependencies:
138 LWP, Sys::Syslog, POSIX. And Data::Dumper (when debugging is enabled),
139 and IO::Select (if parallel downloads are enabled).
140
141 Differences with respect to the previous versions
142
143 * when downloading CRLs via https, the server certificate is not checked,
144 neither for the correct DNS name nor for being issued by a valid CA. Since
145 the CRL in itself is signed, this is not a security vulnerability. If
146 stricter checking is anyway desired, and the Crypt::SSLeay perl module has
147 been installed, set the HTTPS_CA_FILE environment variable before invoking
148 fetch-crl -- but keep in mind that the DNS name verification is limited
149 and will (incorrectly) reject DNS names if these are listed only in the
150 subjectAlternativeName of the server certificate
151 * Existing files with a name that matches a CRL target name are overwritten,
152 even if they did not originally contain CRL data. In v2 this was configurable
153 via the FORCE_OVERWRITE configuration setting. In version 3, files are
154 overwritten by default, and this can no longer be configured.
155 * fetch-crl3 will no longer check CA certificates for consistency or validity
156 by themselves, only retrieved CRLs are verified
157
158 Downsides of the new version
159
160 * it requires perl5 to be installed (tested with perl 5.8.0 and higher) with
161 libwww-perl, whereas version 2 only required a traditional Bourne shell
162 * requires a version of OpenSSL (0.9.5a or better) to be installed. Needs
163 OpenSSL 1.0.0 (at least beta5) for dual-hash support.
164 * when using parallel downloads, it can only run on pure-POSIX systems
165 * parallelism in combination with the NSS database output format is not tested
166 * Even when only the NSS database output format has been selected, OpenSSL is
167 still needed for verification and processing
168
169
170 ==============================================================================
171
172 The change log below applies to the 1.x and 2.x series fetch-crl and is
173 included for historical purposes only. Fetch-crl3, with which this
174 changes file is being shipped, is a complete re-write of the utility.
175 Although a lot of backwards compatibility has been preserves, there have
176 been significant changes and the information below should NOT be used
177 to infer any behaviour of fetch-crl3.
178
179 Fetch-crl 1.x and 2.x were released under the EU DataGrid License.
180
181 Changes in version EGP 2.8.5
182 ----------------------------
183 (2010.06.03)
184
185 * fetch-crl was occasionally leaving behind {hash}.r0.XXXXXX.r0 files
186 This has been fixed in this release (patch thanks to Jason Smith, BNL)
187 * man page was not compliant to Debian guidelines, this has been fixed
188 (patch thanks to Mattias Ellert, Uppsala University)
189
190 Changes in version EGP 2.8.4
191 ----------------------------
192 (2010.04.04)
193
194 * Fixes error when randomWait is not set [RH Bug 579488]
195
196 Changes in version EGP 2.8.3
197 ----------------------------
198 (2010.03.28)
199
200 * Preserve SELinux context for CRL files if SElinux status program exists
201 and selinux is enabled (RH bug 577403)
202 * Fix argument parsing on syslog facility specification (RH bug 577387)
203 * Increase granularity of the RandomWait and allow for 0 in -r option
204
205 Changes in version EGP 2.8.2
206 ----------------------------
207 (2010.03.03)
208
209 * Improved support for multiple CRL URLs by downloading until a success
210 is achieved, instead of downloading all of them
211 * Imported randomwait patch from Steve Traylen
212
213 Changes in version EGP 2.8.1
214 ----------------------------
215 (2010.01.26)
216
217 * The installed CRL file is re-checked for validity to catch file system
218 errors and local disk corruption. When possible, it will try to restore
219 a backup copy. Failures are not subject to aging tolerance.
220
221 Changes in version EGP 2.8.0
222 ----------------------------
223 (2009.09.22)
224
225 * The RPM packaging has been overhauled and is now sufficiently conformant
226 to EPEL and FedoraProject guidelines.
227 * New init scripts and a cron job entry have been added to allow management
228 of fetch-crl via the chkconfig mechanism
229
230 These changes were contributed by Steve Traylen (CERN, Geneva, CH).
231
232 Changes in version EGP 2.7.0
233 ----------------------------
234 (2009.01.25)
235
236 * Warnings and errors are now counted. If there are errors in the download
237 or verification process for one or more CRLs, the exit status will be 1;
238 if there are errors in the local setup or in the script invocation, the
239 exit status will be 2.
240 * The installed CRLs no longer have the textual representation of the CRL,
241 but only the PEM data blob, thus reducing IO and memory requirements.
242 * the CRL aging threshold is now set by default to 24 hours. The previous
243 default was 0. The CRL aging threshold is set in the config file using
244 CRL_AGING_THRESHOLD=<xx>, or with the "-a" command-line argument.
245 * Default network timeouts reduced to 10 seconds (was 30) and retries to 2
246 * Added caching and conditional downloading. When CACHEDIR is set, the
247 original downloads are preserved and wget timestamping mode enabled.
248 When the content did not change, only the timestamp on the installed
249 CRL is updated. If SLOPPYCRLHASHES is set, the has is calculated based
250 on the name of the crl_url file, otherwise it is taken from the CRL itself.
251 - The CACHEDIR must be exclusively writable by the user running fetch-crl
252 - Setting CACHEDIR significantly reduced the bandwidth used by fetch-crl
253 * Added RESETPATHMODE setting in sysconfig. It defines whether or not to
254 set re-set $PATH to "/bin:/usr/bin" before start. The search for OpenSSL
255 may be done based on the old path.
256 yes=always replace; searchopenssl=search for openssl first and then reset;
257 no=keep original path, whatever that me be (may be empty if called from cron)
258 Default="yes". This replaces the hard-coded path in the tool!
259 * Hidden "FORCE_OVERWRITE" option now has a regular name. This is backwards-
260 compatible. Set FORCE_OVERWRITE=yes if you want files overwritten that
261 have a CRL-like name and ought to have CRL content, but currently do not.
262 * Addresses gLite Savannah bugs 28418 and 29559. Bug 27023 is partially
263 addressed. Bug 20062 can be remedied with WGET_OPTS arguments.
264 Addresses OSG ticket 4673.
265
266 Changes in version EGP 2.6.6
267 ----------------------------
268 (2007.09.16)
269 (version 2.5.5 is invalid and was not publicly released)
270
271 * Added obscure configuration parameter to allow overwriting of
272 arbitrary data files with a downloaded CRL (on request of
273 CERN, see https://savannah.cern.ch/bugs/index.php?29559)
274
275 Changes in version EGP 2.6.4
276 ----------------------------
277 (2007.08.15)
278
279 * Expired CA issuer certificate now gives a warning instead of an error
280 with the full verification result message
281 * additional logfile output target can be selected via the configuration file
282 * CRL aging threshold documented in manual page. Errors will now also be
283 generated in the CRL download failed consistently and the current CRL
284 has already expired
285
286 Changes in version EGP 2.6.3
287 ----------------------------
288 (2006.11.13)
289
290 * cron job example: fetch-crl invocation syntax error corrected
291
292 Changes in version EGP 2.6.2
293 ----------------------------
294 (2006.10.27)
295
296 * fixed bug: older wget versions do not recognise --no-check-certificate
297
298 Changes in version EGP 2.6.1
299 ----------------------------
300 (2006.10.25)
301
302 * fixed local timezone vs UTC error in LastUpdate CRL validation comparison
303 * fixed time comparison is the one-hour LastUpdate/download tolerance
304 (both fixes thanks to Alain Roy)
305 * added support for directory names containing whitespace
306 * added support for syslog reporting (via -f option or SYSLOGFACILITY directive)
307 * SERVERCERTCHECK=no is now the default. It can be reset via the configuration
308 file, or using the "--check-server-certificate" commandline option
309 * the main configuration file location (formerly fixed to be
310 /etc/sysconfig/fetch-crl) can now be set via the variable $FETCH_CRL_SYSCONFIG
311 * logfile format timestamp and tag have been normalised
312
313 Changes in version EGP 2.6
314 --------------------------
315 (2006.05.20)
316
317 * if the current local CRL has a lastUpdate time in the future, and the
318 newly downloaded CRL is older that the current one, allow the installation
319 of the newly downloaded CRL and issue a warning.
320 * added non-suppressable warning in case the newly downloaded CRL has a
321 lastUpdate time in the future, but install that CRL anyway (as the local
322 clock might have been wrong).
323
324 Changes in version EGP 2.5
325 --------------------------
326 (2006.01.16)
327
328 * added additional configuration arguments and configuration variables
329 to skip the server certificate check in wget
330 (to support https:// URLs where the server is authenticated with
331 a certificate that is not part of it's own trusted domain, such as
332 the KISTI URL)
333
334 Changes in version EGP 2.4
335 --------------------------
336 (2005.11.15)
337
338 * for those platforms that support the stat(1) command, and in case the
339 .crl_url file is named after the hash of the crl subject name to download,
340 error eporting for individual download errors can be suppressed for
341 a configurable amount of time as set via the "-a" option (unit: hours).
342
343 Changes in version EGP 2.3
344 --------------------------
345 (2005.11.05)
346
347 * do not replace recent CRLs with ones that have an older lastUpdate
348 timestamp (prevents ARP/DNS DoS attacks)
349
350 Changes in version EGP 2.2
351 --------------------------
352 (2005.10.27)
353
354 * secure http download by wget recognise the CAs in the trusted directory.
355 solves the issue described in the LCG bug tracking system
356 https://savannah.cern.ch/bugs/index.php?func=detailitem&item_id=12182
357
358 Changes in version EGP 2.1
359 --------------------------
360 (2005.08.12)
361 * specifically look for the most recent version of OpenSSL. The
362 one in GLOBUS_LOCATION (which used to take precedence in the
363 previous releases) is outdated in many cases and caused
364 troubles on the LCG production systems in validating v2 CRLs
365 * added manual page fetch-crl(8)
366
367 Changes in version EGP 2.0
368 --------------------------
369 (2005.02.28)
370 * name of the installed script changed to "fetch-crl"
371 * the cronjob script is no longer installed by default, but supplied
372 as an example in the %doc directory
373 * RPM is now relocatable (default install in /usr)
374 * READMA and CHANGES file now inclued in %doc tree
375 * make install now installs
376 * version increased to 2.0
377
378 Changes in version EGP 1.9
379 --------------------------
380 (2005.02.24)
381 * the content of the final target CRL file is now checked for
382 containing a valid CRL if it already exists. If it does not
383 contain a CRL, an error is displayed and the file left untouched
384 So making the final ".r0" file in ${outdir} a link to something else
385 will not work, preventing an escalation in the final stage.
386
387 Changes in version EGP 1.8
388 --------------------------
389 (changes from Fabio's version 1.7, 2005.02.24)
390
391 * All temporary files (the initial CRL download using wget
392 and the PEM-converted version of that file) are now created using
393 mktemp
394 * the RetrieveFileByURL function will not overwrite files that
395 have any data in them
396 * Note that the script can be run by a non-priviledged user, but
397 that the output directory must be made writable by that user
398 in an out-of-band way.
