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

376 Imported with consent of Fabio Hernandez and Steve Traylen from
377 the original EDG repository.
