a9d2bc49 | 5 | Changes between 0.9.6 and 0.9.7 [xx XXX 2001] |
a43cf9fa | 6 | |
f2346808 | 7 | Both OpenSSL 0.9.6a (bugfix release, 5 Apr 2001) and OpenSSL 0.9.7 |
a9d2bc49 BM |
8 | are based on OpenSSL 0.9.6. |
9 | Change log entries are tagged as follows: | |
f2346808 BM |
10 | -) applies to 0.9.6a (/0.9.6b) only |
11 | *) applies to 0.9.6a (/0.9.6b) and 0.9.7 | |
a9d2bc49 BM |
12 | +) applies to 0.9.7 only |
13 | ||
c962479b DSH |
14 | +) Fix various bugs related to DSA S/MIME verification. Handle missing |
15 | parameters in DSA public key structures and return an error in the | |
16 | DSA routines if parameters are absent. | |
17 | [Steve Henson] | |
18 | ||
19 | +) Fix ASN1 decoder when decoding type ANY and V_ASN1_OTHER: since this | |
20 | needs to match any other type at all we need to manually clear the | |
21 | tag cache. | |
22 | [Steve Henson] | |
23 | ||
2a8a10ed GT |
24 | +) Changes to the "openssl engine" utility to include; |
25 | - verbosity levels ('-v', '-vv', and '-vvv') that provide information | |
26 | about an ENGINE's available control commands. | |
27 | - executing control commands from command line arguments using the | |
28 | '-pre' and '-post' switches. '-post' is only used if '-t' is | |
29 | specified and the ENGINE is successfully initialised. The syntax for | |
30 | the individual commands are colon-separated, for example; | |
31 | openssl engine chil -pre FORK_CHECK:0 -pre SO_PATH:/lib/test.so | |
32 | [Geoff] | |
33 | ||
34 | +) New dynamic control command support for ENGINEs. ENGINEs can now | |
35 | declare their own commands (numbers), names (strings), descriptions, | |
36 | and input types for run-time discovery by calling applications. A | |
37 | subset of these commands are implicitly classed as "executable" | |
38 | depending on their input type, and only these can be invoked through | |
39 | the new string-based API function ENGINE_ctrl_cmd_string(). (Eg. this | |
40 | can be based on user input, config files, etc). The distinction is | |
41 | that "executable" commands cannot return anything other than a boolean | |
42 | result and can only support numeric or string input, whereas some | |
43 | discoverable commands may only be for direct use through | |
44 | ENGINE_ctrl(), eg. supporting the exchange of binary data, function | |
45 | pointers, or other custom uses. The "executable" commands are to | |
46 | support parameterisations of ENGINE behaviour that can be | |
47 | unambiguously defined by ENGINEs and used consistently across any | |
48 | OpenSSL-based application. Commands have been added to all the | |
49 | existing hardware-supporting ENGINEs, noticeably "SO_PATH" to allow | |
50 | control over shared-library paths without source code alterations. | |
51 | [Geoff] | |
52 | ||
53 | +) Changed all ENGINE implementations to dynamically allocate their | |
54 | ENGINEs rather than declaring them statically. Apart from this being | |
55 | necessary with the removal of the ENGINE_FLAGS_MALLOCED distinction, | |
56 | this also allows the implementations to compile without using the | |
57 | internal engine_int.h header. | |
58 | [Geoff] | |
59 | ||
4d6115a5 GT |
60 | +) Minor adjustment to "rand" code. RAND_get_rand_method() now returns a |
61 | 'const' value. Any code that should be able to modify a RAND_METHOD | |
62 | should already have non-const pointers to it (ie. they should only | |
63 | modify their own ones). | |
64 | [Geoff] | |
65 | ||
2a8a10ed | 66 | +) Made a variety of little tweaks to the ENGINE code. |
4d6115a5 GT |
67 | - "atalla" and "ubsec" string definitions were moved from header files |
68 | to C code. "nuron" string definitions were placed in variables | |
69 | rather than hard-coded - allowing parameterisation of these values | |
70 | later on via ctrl() commands. | |
71 | - Removed unused "#if 0"'d code. | |
72 | - Fixed engine list iteration code so it uses ENGINE_free() to release | |
73 | structural references. | |
74 | - Constified the RAND_METHOD element of ENGINE structures. | |
75 | - Constified various get/set functions as appropriate and added | |
76 | missing functions (including a catch-all ENGINE_cpy that duplicates | |
77 | all ENGINE values onto a new ENGINE except reference counts/state). | |
78 | - Removed NULL parameter checks in get/set functions. Setting a method | |
79 | or function to NULL is a way of cancelling out a previously set | |
80 | value. Passing a NULL ENGINE parameter is just plain stupid anyway | |
81 | and doesn't justify the extra error symbols and code. | |
82 | - Deprecate the ENGINE_FLAGS_MALLOCED define and move the area for | |
83 | flags from engine_int.h to engine.h. | |
84 | - Changed prototypes for ENGINE handler functions (init(), finish(), | |
85 | ctrl(), key-load functions, etc) to take an (ENGINE*) parameter. | |
86 | [Geoff] | |
87 | ||
6e6d04e2 BM |
88 | *) Move 'if (!initialized) RAND_poll()' into regions protected by |
89 | CRYPTO_LOCK_RAND. This is not strictly necessary, but avoids | |
3a25b96c | 90 | having multiple threads call RAND_poll() concurrently. |
6e6d04e2 BM |
91 | [Bodo Moeller] |
92 | ||
93 | *) In crypto/rand/md_rand.c, replace 'add_do_not_lock' flag by a | |
94 | combination of a flag and a thread ID variable. | |
95 | Otherwise while one thread is in ssleay_rand_bytes (which sets the | |
96 | flag), *other* threads can enter ssleay_add_bytes without obeying | |
97 | the CRYPTO_LOCK_RAND lock (and may even illegaly release the lock | |
98 | that they do not hold after the first thread unsets add_do_not_lock). | |
99 | [Bodo Moeller] | |
100 | ||
c962479b | 101 | >>>>>>> 1.823 |
a9d2bc49 | 102 | +) Implement binary inversion algorithm for BN_mod_inverse in addition |
7d0d0996 | 103 | to the algorithm using long divison. The binary algorithm can be |
1f224bf0 BM |
104 | used only if the modulus is odd. On 32-bit systems, it is faster |
105 | only for relatively small moduli (roughly 20-30% for 128-bit moduli, | |
106 | roughly 5-15% for 256-bit moduli), so we use it only for moduli | |
107 | up to 450 bits. In 64-bit environments, the binary algorithm | |
108 | appears to be advantageous for much longer moduli; here we use it | |
109 | for moduli up to 2048 bits. | |
7d0d0996 BM |
110 | [Bodo Moeller] |
111 | ||
f2346808 | 112 | *) Change bctest again: '-x' expressions are not available in all |
5f1fddbb BM |
113 | versions of 'test'. |
114 | [Bodo Moeller] | |
115 | ||
a9d2bc49 BM |
116 | -) OpenSSL 0.9.6a released [5 Apr 2001] |
117 | ||
4ac881ed RL |
118 | *) Fix a couple of memory leaks in PKCS7_dataDecode() |
119 | [Steve Henson, reported by Heyun Zheng <hzheng@atdsprint.com>] | |
120 | ||
967d95f0 RL |
121 | *) Change Configure and Makefiles to provide EXE_EXT, which will contain |
122 | the default extension for executables, if any. Also, make the perl | |
123 | scripts that use symlink() to test if it really exists and use "cp" | |
124 | if it doesn't. All this made OpenSSL compilable and installable in | |
125 | CygWin. | |
126 | [Richard Levitte] | |
127 | ||
a9d2bc49 | 128 | +) Rewrite CHOICE field setting in ASN1_item_ex_d2i(). The old code |
722ca278 DSH |
129 | could not support the combine flag in choice fields. |
130 | [Steve Henson] | |
131 | ||
a9d2bc49 BM |
132 | -) Fix for asn1_GetSequence() for indefinite length constructed data. |
133 | If SEQUENCE is length is indefinite just set c->slen to the total | |
134 | amount of data available. | |
135 | [Steve Henson, reported by shige@FreeBSD.org] | |
136 | [This change does not apply to 0.9.7.] | |
137 | ||
884e2608 BM |
138 | *) Change bctest to avoid here-documents inside command substitution |
139 | (workaround for FreeBSD /bin/sh bug). | |
6186ef93 BM |
140 | For compatibility with Ultrix, avoid shell functions (introduced |
141 | in the bctest version that searches along $PATH). | |
884e2608 BM |
142 | [Bodo Moeller] |
143 | ||
080b8cad RL |
144 | *) Rename 'des_encrypt' to 'des_encrypt1'. This avoids the clashes |
145 | with des_encrypt() defined on some operating systems, like Solaris | |
146 | and UnixWare. | |
147 | [Richard Levitte] | |
148 | ||
6a5b52ef UM |
149 | *) Check the result of RSA-CRT (see D. Boneh, R. DeMillo, R. Lipton: |
150 | On the Importance of Eliminating Errors in Cryptographic | |
080b8cad RL |
151 | Computations, J. Cryptology 14 (2001) 2, 101-119, |
152 | http://theory.stanford.edu/~dabo/papers/faults.ps.gz). | |
153 | [Ulf Moeller] | |
6a5b52ef UM |
154 | |
155 | *) MIPS assembler BIGNUM division bug fix. | |
6d864b70 UM |
156 | [Andy Polyakov] |
157 | ||
c9fd9152 UM |
158 | *) Disabled incorrect Alpha assembler code. |
159 | [Richard Levitte] | |
160 | ||
a9d2bc49 BM |
161 | -) Fix PKCS#7 decode routines so they correctly update the length |
162 | after reading an EOC for the EXPLICIT tag. | |
163 | [Steve Henson] | |
164 | [This change does not apply to 0.9.7.] | |
165 | ||
02ee8626 DSH |
166 | *) Fix bug in PKCS#12 key generation routines. This was triggered |
167 | if a 3DES key was generated with a 0 initial byte. Include | |
168 | PKCS12_BROKEN_KEYGEN compilation option to retain the old | |
169 | (but broken) behaviour. | |
170 | [Steve Henson] | |
171 | ||
6e678305 RL |
172 | *) Enhance bctest to search for a working bc along $PATH and print |
173 | it when found. | |
174 | [Tim Rice <tim@multitalents.net> via Richard Levitte] | |
175 | ||
a9d2bc49 | 176 | +) Add a 'copy_extensions' option to the 'ca' utility. This copies |
791bd0cd DSH |
177 | extensions from a certificate request to the certificate. |
178 | [Steve Henson] | |
179 | ||
a9d2bc49 | 180 | +) Allow multiple 'certopt' and 'nameopt' options to be separated |
535d79da DSH |
181 | by commas. Add 'namopt' and 'certopt' options to the 'ca' config |
182 | file: this allows the display of the certificate about to be | |
183 | signed to be customised, to allow certain fields to be included | |
184 | or excluded and extension details. The old system didn't display | |
185 | multicharacter strings properly, omitted fields not in the policy | |
186 | and couldn't display additional details such as extensions. | |
187 | [Steve Henson] | |
188 | ||
5d809414 BM |
189 | *) Fix memory leaks in err.c: free err_data string if necessary; |
190 | don't write to the wrong index in ERR_set_error_data. | |
f51cf14b BM |
191 | [Bodo Moeller] |
192 | ||
a9d2bc49 | 193 | +) Function EC_POINTs_mul for simultaneous scalar multiplication |
38374911 BM |
194 | of an arbitrary number of elliptic curve points, optionally |
195 | including the generator defined for the EC_GROUP. | |
196 | EC_POINT_mul is a simple wrapper function for the typical case | |
197 | that the point list has just one item (besides the optional | |
198 | generator). | |
48fe4d62 BM |
199 | [Bodo Moeller] |
200 | ||
a9d2bc49 | 201 | +) First EC_METHODs for curves over GF(p): |
48fe4d62 BM |
202 | |
203 | EC_GFp_simple_method() uses the basic BN_mod_mul and BN_mod_sqr | |
204 | operations and provides various method functions that can also | |
205 | operate with faster implementations of modular arithmetic. | |
206 | ||
207 | EC_GFp_mont_method() reuses most functions that are part of | |
208 | EC_GFp_simple_method, but uses Montgomery arithmetic. | |
209 | ||
210 | [Bodo Moeller; point addition and point doubling | |
211 | implementation directly derived from source code provided by | |
212 | Lenka Fibikova <fibikova@exp-math.uni-essen.de>] | |
213 | ||
a9d2bc49 | 214 | +) Framework for elliptic curves (crypto/ec/ec.h, crypto/ec/ec_lcl.h, |
48fe4d62 BM |
215 | crypto/ec/ec_lib.c): |
216 | ||
6f8f4431 BM |
217 | Curves are EC_GROUP objects (with an optional group generator) |
218 | based on EC_METHODs that are built into the library. | |
48fe4d62 BM |
219 | |
220 | Points are EC_POINT objects based on EC_GROUP objects. | |
221 | ||
222 | Most of the framework would be able to handle curves over arbitrary | |
6f8f4431 BM |
223 | finite fields, but as there are no obvious types for fields other |
224 | than GF(p), some functions are limited to that for now. | |
48fe4d62 BM |
225 | [Bodo Moeller] |
226 | ||
a9d2bc49 | 227 | +) Add the -HTTP option to s_server. It is similar to -WWW, but requires |
251cb4cf RL |
228 | that the file contains a complete HTTP response. |
229 | [Richard Levitte] | |
230 | ||
a9d2bc49 | 231 | +) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl |
b4f682d3 DSH |
232 | change the def and num file printf format specifier from "%-40sXXX" |
233 | to "%-39s XXX". The latter will always guarantee a space after the | |
234 | field while the former will cause them to run together if the field | |
235 | is 40 of more characters long. | |
236 | [Steve Henson] | |
237 | ||
a9d2bc49 | 238 | +) Constify the cipher and digest 'method' functions and structures |
13588350 DSH |
239 | and modify related functions to take constant EVP_MD and EVP_CIPHER |
240 | pointers. | |
241 | [Steve Henson] | |
242 | ||
c1081080 BM |
243 | *) Implement ssl23_peek (analogous to ssl23_read), which previously |
244 | did not exist. | |
245 | [Bodo Moeller] | |
246 | ||
bb62a8b0 BM |
247 | *) Replace rdtsc with _emit statements for VC++ version 5. |
248 | [Jeremy Cooper <jeremy@baymoo.org>] | |
bd9e2e4c | 249 | |
a9d2bc49 | 250 | +) Hide BN_CTX structure details in bn_lcl.h instead of publishing them |
48fe4d62 | 251 | in <openssl/bn.h>. Also further increase BN_CTX_NUM to 32. |
c62b26fd BM |
252 | [Bodo Moeller] |
253 | ||
a9d2bc49 | 254 | +) Modify EVP_Digest*() routines so they now return values. Although the |
2dc769a1 DSH |
255 | internal software routines can never fail additional hardware versions |
256 | might. | |
257 | [Steve Henson] | |
258 | ||
a9d2bc49 | 259 | +) Clean up crypto/err/err.h and change some error codes to avoid conflicts: |
5277d7cb BM |
260 | |
261 | Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7 | |
262 | (= ERR_R_PKCS7_LIB); it is now 64 instead of 32. | |
263 | ||
264 | ASN1 error codes | |
265 | ERR_R_NESTED_ASN1_ERROR | |
266 | ... | |
267 | ERR_R_MISSING_ASN1_EOS | |
268 | were 4 .. 9, conflicting with | |
269 | ERR_LIB_RSA (= ERR_R_RSA_LIB) | |
270 | ... | |
271 | ERR_LIB_PEM (= ERR_R_PEM_LIB). | |
272 | They are now 58 .. 63 (i.e., just below ERR_R_FATAL). | |
273 | ||
274 | Add new error code 'ERR_R_INTERNAL_ERROR'. | |
275 | [Bodo Moeller] | |
276 | ||
a9d2bc49 | 277 | +) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock |
5277d7cb BM |
278 | suffices. |
279 | [Bodo Moeller] | |
280 | ||
a9d2bc49 | 281 | +) New option '-subj arg' for 'openssl req' and 'openssl ca'. This |
bad40585 BM |
282 | sets the subject name for a new request or supersedes the |
283 | subject name in a given request. Formats that can be parsed are | |
284 | 'CN=Some Name, OU=myOU, C=IT' | |
285 | and | |
286 | 'CN=Some Name/OU=myOU/C=IT'. | |
287 | ||
288 | Add options '-batch' and '-verbose' to 'openssl req'. | |
289 | [Massimiliano Pala <madwolf@hackmasters.net>] | |
290 | ||
757a8b46 RL |
291 | *) Make it possible to reuse SSLv2 sessions. |
292 | [Richard Levitte] | |
293 | ||
a9d2bc49 | 294 | +) Introduce the possibility to access global variables through |
62dc5aad RL |
295 | functions on platform were that's the best way to handle exporting |
296 | global variables in shared libraries. To enable this functionality, | |
297 | one must configure with "EXPORT_VAR_AS_FN" or defined the C macro | |
298 | "OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter | |
299 | is normally done by Configure or something similar). | |
300 | ||
301 | To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL | |
302 | in the source file (foo.c) like this: | |
303 | ||
304 | OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1; | |
305 | OPENSSL_IMPLEMENT_GLOBAL(double,bar); | |
306 | ||
307 | To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL | |
308 | and OPENSSL_GLOBAL_REF in the header file (foo.h) like this: | |
309 | ||
310 | OPENSSL_DECLARE_GLOBAL(int,foo); | |
311 | #define foo OPENSSL_GLOBAL_REF(foo) | |
312 | OPENSSL_DECLARE_GLOBAL(double,bar); | |
313 | #define bar OPENSSL_GLOBAL_REF(bar) | |
314 | ||
315 | The #defines are very important, and therefore so is including the | |
316 | header file everywere where the defined globals are used. | |
317 | ||
318 | The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition | |
319 | of ASN.1 items, but that structure is a bt different. | |
320 | ||
321 | The largest change is in util/mkdef.pl which has been enhanced with | |
322 | better and easier to understand logic to choose which symbols should | |
323 | go into the Windows .def files as well as a number of fixes and code | |
324 | cleanup (among others, algorithm keywords are now sorted | |
325 | lexicographically to avoid constant rewrites). | |
326 | [Richard Levitte] | |
327 | ||
f23478c3 DSH |
328 | *) In copy_email() check for >= 0 as a return value for |
329 | X509_NAME_get_index_by_NID() since 0 is a valid index. | |
330 | [Steve Henson reported by Massimiliano Pala <madwolf@opensca.org>] | |
331 | ||
a9d2bc49 | 332 | +) In BN_div() keep a copy of the sign of 'num' before writing the |
3d2e469c DSH |
333 | result to 'rm' because if rm==num the value will be overwritten |
334 | and produce the wrong result if 'num' is negative: this caused | |
335 | problems with BN_mod() and BN_nnmod(). | |
336 | [Steve Henson] | |
337 | ||
a9d2bc49 | 338 | +) Function OCSP_request_verify(). This checks the signature on an |
fafc7f98 DSH |
339 | OCSP request and verifies the signer certificate. The signer |
340 | certificate is just checked for a generic purpose and OCSP request | |
341 | trust settings. | |
342 | [Steve Henson] | |
343 | ||
a9d2bc49 | 344 | +) Add OCSP_check_validity() function to check the validity of OCSP |
f1965221 DSH |
345 | responses. OCSP responses are prepared in real time and may only |
346 | be a few seconds old. Simply checking that the current time lies | |
347 | between thisUpdate and nextUpdate max reject otherwise valid responses | |
348 | caused by either OCSP responder or client clock innacuracy. Instead | |
349 | we allow thisUpdate and nextUpdate to fall within a certain period of | |
350 | the current time. The age of the response can also optionally be | |
351 | checked. Two new options -validity_period and -status_age added to | |
352 | ocsp utility. | |
353 | [Steve Henson] | |
354 | ||
a9d2bc49 | 355 | +) If signature or public key algorithm is unrecognized print out its |
4ff18c8c DSH |
356 | OID rather that just UNKOWN. |
357 | [Steve Henson] | |
358 | ||
db4a4659 DSH |
359 | *) Avoid coredump with unsupported or invalid public keys by checking if |
360 | X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when | |
361 | PKCS7_verify() fails with non detached data. | |
362 | [Steve Henson] | |
363 | ||
a9d2bc49 | 364 | +) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and |
d7c06e9e DSH |
365 | OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate |
366 | ID to be generated from the issuer certificate alone which can then be | |
367 | passed to OCSP_id_issuer_cmp(). | |
368 | [Steve Henson] | |
369 | ||
a9d2bc49 | 370 | +) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new |
386828d0 DSH |
371 | ASN1 modules to export functions returning ASN1_ITEM pointers |
372 | instead of the ASN1_ITEM structures themselves. This adds several | |
373 | new macros which allow the underlying ASN1 function/structure to | |
374 | be accessed transparently. As a result code should not use ASN1_ITEM | |
375 | references directly (such as &X509_it) but instead use the relevant | |
376 | macros (such as ASN1_ITEM_rptr(X509)). This option is to allow | |
377 | use of the new ASN1 code on platforms where exporting structures | |
378 | is problematical (for example in shared libraries) but exporting | |
379 | functions returning pointers to structures is not. | |
380 | [Steve Henson] | |
381 | ||
a9d2bc49 | 382 | +) Add support for overriding the generation of SSL/TLS session IDs. |
fa2b8db4 GT |
383 | These callbacks can be registered either in an SSL_CTX or per SSL. |
384 | The purpose of this is to allow applications to control, if they wish, | |
385 | the arbitrary values chosen for use as session IDs, particularly as it | |
386 | can be useful for session caching in multiple-server environments. A | |
387 | command-line switch for testing this (and any client code that wishes | |
388 | to use such a feature) has been added to "s_server". | |
389 | [Geoff Thorpe, Lutz Jaenicke] | |
390 | ||
a9d2bc49 | 391 | +) Modify mkdef.pl to recognise and parse prprocessor conditionals |
d399fdf8 RL |
392 | of the form '#if defined(...) || defined(...) || ...' and |
393 | '#if !defined(...) && !defined(...) && ...'. This also avoids | |
394 | the growing number of special cases it was previously handling. | |
395 | [Richard Levitte] | |
396 | ||
5003a61b UM |
397 | *) Don't use getenv in library functions when run as setuid/setgid. |
398 | New function OPENSSL_issetugid(). | |
399 | [Ulf Moeller] | |
400 | ||
a9d2bc49 | 401 | +) Make all configuration macros available for application by making |
cf1b7d96 RL |
402 | sure they are available in opensslconf.h, by giving them names starting |
403 | with "OPENSSL_" to avoid conflicts with other packages and by making | |
404 | sure e_os2.h will cover all platform-specific cases together with | |
405 | opensslconf.h. | |
2affbab9 RL |
406 | Additionally, it is now possible to define configuration/platform- |
407 | specific names (called "system identities"). In the C code, these | |
408 | are prefixed with "OPENSSL_SYSNAME_". e_os2.h will create another | |
409 | macro with the name beginning with "OPENSSL_SYS_", which is determined | |
410 | from "OPENSSL_SYSNAME_*" or compiler-specific macros depending on | |
411 | what is available. | |
cf1b7d96 RL |
412 | [Richard Levitte] |
413 | ||
a9d2bc49 | 414 | +) New option -set_serial to 'req' and 'x509' this allows the serial |
acba75c5 DSH |
415 | number to use to be specified on the command line. Previously self |
416 | signed certificates were hard coded with serial number 0 and the | |
417 | CA options of 'x509' had to use a serial number in a file which was | |
418 | auto incremented. | |
419 | [Steve Henson] | |
420 | ||
934397ec BM |
421 | *) Avoid false positives in memory leak detection code (crypto/mem_dbg.c) |
422 | due to incorrect handling of multi-threading: | |
423 | ||
424 | 1. Fix timing glitch in the MemCheck_off() portion of CRYPTO_mem_ctrl(). | |
425 | ||
426 | 2. Fix logical glitch in is_MemCheck_on() aka CRYPTO_is_mem_check_on(). | |
427 | ||
428 | 3. Count how many times MemCheck_off() has been called so that | |
429 | nested use can be treated correctly. This also avoids | |
430 | inband-signalling in the previous code (which relied on the | |
431 | assumption that thread ID 0 is impossible). | |
432 | [Bodo Moeller] | |
433 | ||
a9d2bc49 | 434 | +) New options to 'ca' utility to support V2 CRL entry extensions. |
a6b7ffdd DSH |
435 | Currently CRL reason, invalidity date and hold instruction are |
436 | supported. Add new CRL extensions to V3 code and some new objects. | |
437 | [Steve Henson] | |
438 | ||
f30d34f3 LJ |
439 | *) Add "-rand" option also to s_client and s_server. |
440 | [Lutz Jaenicke] | |
441 | ||
a9d2bc49 | 442 | +) New function EVP_CIPHER_CTX_set_padding() this is used to |
f2e5ca84 DSH |
443 | disable standard block padding (aka PKCS#5 padding) in the EVP |
444 | API, which was previously mandatory. This means that the data is | |
445 | not padded in any way and so the total length much be a multiple | |
446 | of the block size, otherwise an error occurs. | |
447 | [Steve Henson] | |
448 | ||
a9d2bc49 | 449 | +) Initial (incomplete) OCSP SSL support. |
cdc7b8cc DSH |

720235ee UM |
452 | *) Fix CPU detection on Irix 6.x. |
453 | [Kurt Hockenbury <khockenb@stevens-tech.edu> and | |
454 | "Bruce W. Forsberg" <bruce.forsberg@baesystems.com>] | |
455 | ||
a9d2bc49 | 456 | +) New function OCSP_parse_url(). This splits up a URL into its host, |
67c18019 DSH |
457 | port and path components: primarily to parse OCSP URLs. New -url |
458 | option to ocsp utility. | |
459 | [Steve Henson] | |
460 | ||
a9d2bc49 | 461 | +) New nonce behavior. The return value of OCSP_check_nonce() now |
46a58ab9 DSH |
462 | reflects the various checks performed. Applications can decide |
463 | whether to tolerate certain situations such as an absent nonce | |
464 | in a response when one was present in a request: the ocsp application | |
465 | just prints out a warning. New function OCSP_add1_basic_nonce() | |
466 | this is to allow responders to include a nonce in a response even if | |
467 | the request is nonce-less. | |
468 | [Steve Henson] | |
469 | ||
a9d2bc49 BM |
470 | *) Fix X509_NAME bug which produced incorrect encoding if X509_NAME |
471 | was empty. | |
472 | [This change does not apply to 0.9.7.] | |
473 | ||
94fcd013 DSH |
474 | *) Use the cached encoding of an X509_NAME structure rather than |
475 | copying it. This is apparently the reason for the libsafe "errors" | |
476 | but the code is actually correct. | |
477 | [Steve Henson] | |
478 | ||
a9d2bc49 | 479 | +) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are |
620cea37 BM |
480 | skipped when using openssl x509 multiple times on a single input file, |
481 | e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) <certs". | |
482 | [Bodo Moeller] | |
483 | ||
a9d2bc49 | 484 | +) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string() |
ccb08f98 DSH |
485 | set string type: to handle setting ASN1_TIME structures. Fix ca |
486 | utility to correctly initialize revocation date of CRLs. | |
487 | [Steve Henson] | |
488 | ||
a9d2bc49 | 489 | +) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override |
836f9960 LJ |
490 | the clients preferred ciphersuites and rather use its own preferences. |
491 | Should help to work around M$ SGC (Server Gated Cryptography) bug in | |
492 | Internet Explorer by ensuring unchanged hash method during stepup. | |
493 | [Lutz Jaenicke] | |
494 | ||
a9d2bc49 | 495 | +) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael |
c47c6196 DSH |
496 | to aes and add a new 'exist' option to print out symbols that don't |
497 | appear to exist. | |
498 | [Steve Henson] | |
499 | ||
a9d2bc49 | 500 | +) Additional options to ocsp utility to allow flags to be set and |
8c950429 DSH |
501 | additional certificates supplied. |
502 | [Steve Henson] | |
503 | ||
a9d2bc49 | 504 | +) Add the option -VAfile to 'openssl ocsp', so the user can give the |
9235adbf RL |
505 | OCSP client a number of certificate to only verify the response |
506 | signature against. | |
507 | [Richard Levitte] | |
508 | ||
57e7d3ce UM |
509 | *) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent |
510 | Bleichenbacher's DSA attack. | |
f2bc6684 BM |
511 | Extend BN_[pseudo_]rand: As before, top=1 forces the highest two bits |
512 | to be set and top=0 forces the highest bit to be set; top=-1 is new | |
513 | and leaves the highest bit random. | |
35ed8cb8 | 514 | [Ulf Moeller, Bodo Moeller] |
57e7d3ce | 515 | |
a9d2bc49 | 516 | +) Update Rijndael code to version 3.0 and change EVP AES ciphers to |
deb2c1a1 DSH |
517 | handle the new API. Currently only ECB, CBC modes supported. Add new |
518 | AES OIDs. Add TLS AES ciphersuites as described in the "AES Ciphersuites | |
519 | for TLS" draft-ietf-tls-ciphersuite-03.txt. | |
520 | [Ben Laurie, Steve Henson] | |
521 | ||
9eea2be6 BM |
522 | *) In the NCONF_...-based implementations for CONF_... queries |
523 | (crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using | |
524 | a temporary CONF structure with the data component set to NULL | |
525 | (which gives segmentation faults in lh_retrieve). | |
526 | Instead, use NULL for the CONF pointer in CONF_get_string and | |
527 | CONF_get_number (which may use environment variables) and directly | |
528 | return NULL from CONF_get_section. | |
529 | [Bodo Moeller] | |
530 | ||
741a9690 UM |
531 | *) Fix potential buffer overrun for EBCDIC. |
532 | [Ulf Moeller] | |
533 | ||
a9d2bc49 | 534 | +) New function OCSP_copy_nonce() to copy nonce value (if present) from |
26e083cc DSH |
535 | request to response. |
536 | [Steve Henson] | |
537 | ||
a9d2bc49 | 538 | +) Functions for OCSP responders. OCSP_request_onereq_count(), |
02e4fbed DSH |
539 | OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info() |
540 | extract information from a certificate request. OCSP_response_create() | |
541 | creates a response and optionally adds a basic response structure. | |
542 | OCSP_basic_add1_status() adds a complete single response to a basic | |
543 | reponse and returns the OCSP_SINGLERESP structure just added (to allow | |
544 | extensions to be included for example). OCSP_basic_add1_cert() adds a | |
545 | certificate to a basic response and OCSP_basic_sign() signs a basic | |
546 | response with various flags. New helper functions ASN1_TIME_check() | |
547 | (checks validity of ASN1_TIME structure) and ASN1_TIME_to_generalizedtime() | |
548 | (converts ASN1_TIME to GeneralizedTime). | |
549 | [Steve Henson] | |
550 | ||
a9d2bc49 | 551 | +) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}() |
88ce56f8 DSH |
552 | in a single operation. X509_get0_pubkey_bitstr() extracts the public_key |
553 | structure from a certificate. X509_pubkey_digest() digests tha public_key | |
554 | contents: this is used in various key identifiers. | |
555 | [Steve Henson] | |
556 | ||
8cff6331 DSH |
557 | *) Tolerate nonRepudiation as being valid for S/MIME signing and certSign |
558 | keyUsage if basicConstraints absent for a CA. | |
559 | [Steve Henson] | |
560 | ||
903872d6 RL |
561 | *) Make SMIME_write_PKCS7() write mail header values with a format that |
562 | is more generally accepted (no spaces before the semicolon), since | |
563 | some programs can't parse those values properly otherwise. Also make | |
564 | sure BIO's that break lines after each write do not create invalid | |
565 | headers. | |
566 | [Richard Levitte] | |
567 | ||
a9d2bc49 | 568 | +) Make sk_sort() tolerate a NULL argument. |
b8470240 DSH |
569 | [Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>] |
570 | ||
a9d2bc49 | 571 | +) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates |
50d51991 DSH |
572 | passed by the function are trusted implicitly. If any of them signed the |
573 | reponse then it is assumed to be valid and is not verified. | |
574 | [Steve Henson] | |
575 | ||
a9d2bc49 BM |
576 | -) Make the CRL encoding routines work with empty SEQUENCE OF. The |
577 | macros previously used would not encode an empty SEQUENCE OF | |
578 | and break the signature. | |
579 | [Steve Henson] | |
580 | [This change does not apply to 0.9.7.] | |
581 | ||
a342cc5a DSH |
582 | *) Zero the premaster secret after deriving the master secret in |
583 | DH ciphersuites. | |
584 | [Steve Henson] | |
585 | ||
a9d2bc49 | 586 | +) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT |
a43cf9fa DSH |
587 | to data. This was previously part of the PKCS7 ASN1 code. This |
588 | was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures. | |
589 | [Steve Henson, reported by Kenneth R. Robinette | |
590 | <support@securenetterm.com>] | |
591 | ||
a9d2bc49 | 592 | +) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1 |
a43cf9fa DSH |
593 | routines: without these tracing memory leaks is very painful. |
594 | Fix leaks in PKCS12 and PKCS7 routines. | |
595 | [Steve Henson] | |
596 | ||
ae0665b8 | 597 | *) Add some EVP_add_digest_alias registrations (as found in |
81a6c781 | 598 | OpenSSL_add_all_digests()) to SSL_library_init() |
ae0665b8 BM |
599 | aka OpenSSL_add_ssl_algorithms(). This provides improved |
600 | compatibility with peers using X.509 certificates | |
601 | with unconventional AlgorithmIdentifier OIDs. | |
602 | [Bodo Moeller] | |

607 | *) ./config script fixes. |
608 | [Ulf Moeller, Richard Levitte] | |
609 | ||
a9d2bc49 | 610 | +) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new(). |
ba8e2824 DSH |
611 | Previously it initialised the 'type' argument to V_ASN1_UTCTIME which |
612 | effectively meant GeneralizedTime would never be used. Now it | |
613 | is initialised to -1 but X509_time_adj() now has to check the value | |
614 | and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or | |
615 | V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime. | |
616 | [Steve Henson, reported by Kenneth R. Robinette | |
617 | <support@securenetterm.com>] | |
618 | ||
a9d2bc49 | 619 | +) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously |
8e8972bb DSH |
620 | result in a zero length in the ASN1_INTEGER structure which was |
621 | not consistent with the structure when d2i_ASN1_INTEGER() was used | |
622 | and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER() | |
623 | to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER() | |
624 | where it did not print out a minus for negative ASN1_INTEGER. | |
625 | [Steve Henson] | |
626 | ||
57108f0a BM |
627 | *) Fix 'openssl passwd -1'. |
628 | [Bodo Moeller] | |
629 | ||
a9d2bc49 | 630 | +) Add summary printout to ocsp utility. The various functions which |
73758d43 DSH |
631 | convert status values to strings have been renamed to: |
632 | OCSP_response_status_str(), OCSP_cert_status_str() and | |
633 | OCSP_crl_reason_str() and are no longer static. New options | |
634 | to verify nonce values and to disable verification. OCSP response | |
635 | printout format cleaned up. | |
636 | [Steve Henson] | |
637 | ||
a9d2bc49 | 638 | +) Add additional OCSP certificate checks. These are those specified |
e8af92fc DSH |
639 | in RFC2560. This consists of two separate checks: the CA of the |
640 | certificate being checked must either be the OCSP signer certificate | |
641 | or the issuer of the OCSP signer certificate. In the latter case the | |
642 | OCSP signer certificate must contain the OCSP signing extended key | |
643 | usage. This check is performed by attempting to match the OCSP | |
644 | signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash | |
645 | in the OCSP_CERTID structures of the response. | |
646 | [Steve Henson] | |
647 | ||
a9d2bc49 | 648 | +) Initial OCSP certificate verification added to OCSP_basic_verify() |
81f169e9 DSH |
649 | and related routines. This uses the standard OpenSSL certificate |
650 | verify routines to perform initial checks (just CA validity) and | |
651 | to obtain the certificate chain. Then additional checks will be | |
652 | performed on the chain. Currently the root CA is checked to see | |
653 | if it is explicitly trusted for OCSP signing. This is used to set | |
654 | a root CA as a global signing root: that is any certificate that | |
655 | chains to that CA is an acceptable OCSP signing certificate. | |
656 | [Steve Henson] | |
657 | ||
a9d2bc49 | 658 | +) New '-extfile ...' option to 'openssl ca' for reading X.509v3 |
dfebac32 BM |
659 | extensions from a separate configuration file. |
660 | As when reading extensions from the main configuration file, | |
661 | the '-extensions ...' option may be used for specifying the | |
662 | section to use. | |
663 | [Massimiliano Pala <madwolf@comune.modena.it>] | |

6308af19 DSH |
665 | *) Change PKCS12_key_gen_asc() so it can cope with non null |
666 | terminated strings whose length is passed in the passlen | |
667 | parameter, for example from PEM callbacks. This was done | |
668 | by adding an extra length parameter to asc2uni(). | |
669 | [Steve Henson, reported by <oddissey@samsung.co.kr>] | |
670 | ||
a9d2bc49 | 671 | +) New OCSP utility. Allows OCSP requests to be generated or |
5782ceb2 DSH |
672 | read. The request can be sent to a responder and the output |
673 | parsed, outputed or printed in text form. Not complete yet: | |
674 | still needs to check the OCSP response validity. | |
675 | [Steve Henson] | |
676 | ||
a9d2bc49 | 677 | +) New subcommands for 'openssl ca': |
c67cdb50 BM |
678 | 'openssl ca -status <serial>' prints the status of the cert with |
679 | the given serial number (according to the index file). | |
680 | 'openssl ca -updatedb' updates the expiry status of certificates | |
681 | in the index file. | |
682 | [Massimiliano Pala <madwolf@comune.modena.it>] | |
683 | ||
a9d2bc49 | 684 | +) New '-newreq-nodes' command option to CA.pl. This is like |
d199858e BM |
685 | '-newreq', but calls 'openssl req' with the '-nodes' option |
686 | so that the resulting key is not encrypted. | |
687 | [Damien Miller <djm@mindrot.org>] | |
688 | ||
a9d2bc49 | 689 | +) New configuration for the GNU Hurd. |

a9d2bc49 | 692 | +) Initial code to implement OCSP basic response verify. This |

694 | certificate and verifies the signature on the response. | |
695 | [Steve Henson] | |
696 | ||
a9d2bc49 | 697 | +) New SSLeay_version code SSLEAY_DIR to determine the compiled-in |
673b3fde BM |
698 | value of OPENSSLDIR. This is available via the new '-d' option |
699 | to 'openssl version', and is also included in 'openssl version -a'. | |

704 | [Bodo Moeller] | |
705 | ||
a9d2bc49 | 706 | +) Allowing defining memory allocation callbacks that will be given |
a5435e8b BM |
707 | file name and line number information in additional arguments |
708 | (a const char* and an int). The basic functionality remains, as | |
709 | well as the original possibility to just replace malloc(), | |
710 | realloc() and free() by functions that do not know about these | |
711 | additional arguments. To register and find out the current | |
712 | settings for extended allocation functions, the following | |
713 | functions are provided: | |
65a22e8e RL |
714 | |
715 | CRYPTO_set_mem_ex_functions | |
716 | CRYPTO_set_locked_mem_ex_functions | |

718 | CRYPTO_get_locked_mem_ex_functions | |
719 | ||
a5435e8b BM |
720 | These work the same way as CRYPTO_set_mem_functions and friends. |
721 | CRYPTO_get_[locked_]mem_functions now writes 0 where such an | |
722 | extended allocation function is enabled. | |
723 | Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where | |
724 | a conventional allocation function is enabled. | |

a9d2bc49 | 731 | +) Finish off removing the remaining LHASH function pointer casts. |
3c914840 | 732 | There should no longer be any prototype-casting required when using |
56a67adb GT |
733 | the LHASH abstraction, and any casts that remain are "bugs". See |
734 | the callback types and macros at the head of lhash.h for details | |

a9d2bc49 | 738 | +) Add automatic query of EGD sockets in RAND_poll() for the unix variant. |
599c0353 LJ |
739 | If an EGD or PRNGD is running and enough entropy is returned, automatic |
740 | seeding like with /dev/[u]random will be performed. | |

a9d2bc49 | 744 | +) Change the Unix RAND_poll() variant to be able to poll several |
361ef5f4 RL |
745 | random devices, as specified by DEVRANDOM, until a sufficient amount |
746 | of data has been collected. We spend at most 10 ms on each file | |
747 | (select timeout) and read in non-blocking mode. DEVRANDOM now | |
748 | defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom" | |
749 | (previously it was just the string "/dev/urandom"), so on typical | |
750 | platforms the 10 ms delay will never occur. | |
751 | Also separate out the Unix variant to its own file, rand_unix.c. | |
752 | For VMS, there's a currently-empty rand_vms.c. | |

754 | ||
a9d2bc49 | 755 | +) Move OCSP client related routines to ocsp_cl.c. These |
0b33bc65 DSH |
756 | provide utility functions which an application needing |
757 | to issue a request to an OCSP responder and analyse the | |
758 | response will typically need: as opposed to those which an | |
759 | OCSP responder itself would need which will be added later. | |
760 | ||
761 | OCSP_request_sign() signs an OCSP request with an API similar | |
762 | to PKCS7_sign(). OCSP_response_status() returns status of OCSP | |
763 | response. OCSP_response_get1_basic() extracts basic response | |
764 | from response. OCSP_resp_find_status(): finds and extracts status | |
765 | information from an OCSP_CERTID structure (which will be created | |
766 | when the request structure is built). These are built from lower | |
767 | level functions which work on OCSP_SINGLERESP structures but | |
768 | wont normally be used unless the application wishes to examine | |
769 | extensions in the OCSP response for example. | |
770 | ||
771 | Replace nonce routines with a pair of functions. | |
772 | OCSP_request_add1_nonce() adds a nonce value and optionally | |
773 | generates a random value. OCSP_check_nonce() checks the | |
774 | validity of the nonce in an OCSP response. | |
775 | [Steve Henson] | |
776 | ||
a9d2bc49 | 777 | +) Change function OCSP_request_add() to OCSP_request_add0_id(). |
8e961835 DSH |
778 | This doesn't copy the supplied OCSP_CERTID and avoids the |
779 | need to free up the newly created id. Change return type | |
780 | to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure. | |
781 | This can then be used to add extensions to the request. | |
782 | Deleted OCSP_request_new(), since most of its functionality | |
783 | is now in OCSP_REQUEST_new() (and the case insensitive name | |
784 | clash) apart from the ability to set the request name which | |
785 | will be added elsewhere. | |
786 | [Steve Henson] | |
787 | ||
a9d2bc49 | 788 | +) Update OCSP API. Remove obsolete extensions argument from |
bf0d176e DSH |
789 | various functions. Extensions are now handled using the new |
790 | OCSP extension code. New simple OCSP HTTP function which | |
791 | can be used to send requests and parse the response. | |
792 | [Steve Henson] | |
793 | ||
a9d2bc49 | 794 | +) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new |
ec5add87 DSH |
795 | ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN |
796 | uses the special reorder version of SET OF to sort the attributes | |
797 | and reorder them to match the encoded order. This resolves a long | |
798 | standing problem: a verify on a PKCS7 structure just after signing | |
799 | it used to fail because the attribute order did not match the | |
800 | encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes: | |
801 | it uses the received order. This is necessary to tolerate some broken | |
802 | software that does not order SET OF. This is handled by encoding | |
803 | as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class) | |
804 | to produce the required SET OF. | |
805 | [Steve Henson] | |
806 | ||
a9d2bc49 | 807 | +) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and |
a6574c21 RL |
808 | OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header |
809 | files to get correct declarations of the ASN.1 item variables. | |
810 | [Richard Levitte] | |
811 | ||
a9d2bc49 | 812 | +) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many |
ecbe0781 DSH |
813 | PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs: |
814 | asn1_check_tlen() would sometimes attempt to use 'ctx' when it was | |
815 | NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i(). | |
816 | New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant | |
817 | ASN1_ITEM and no wrapper functions. | |
818 | [Steve Henson] | |
819 | ||
a9d2bc49 | 820 | +) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These |
4e1209eb DSH |
821 | replace the old function pointer based I/O routines. Change most of |
822 | the *_d2i_bio() and *_d2i_fp() functions to use these. | |
823 | [Steve Henson] | |
824 | ||
a9d2bc49 | 825 | +) Enhance mkdef.pl to be more accepting about spacing in C preprocessor |
3f07fe09 RL |
826 | lines, recognice more "algorithms" that can be deselected, and make |
827 | it complain about algorithm deselection that isn't recognised. | |
828 | [Richard Levitte] | |
829 | ||
a9d2bc49 | 830 | +) New ASN1 functions to handle dup, sign, verify, digest, pack and |
73e92de5 DSH |
831 | unpack operations in terms of ASN1_ITEM. Modify existing wrappers |
832 | to use new functions. Add NO_ASN1_OLD which can be set to remove | |
833 | some old style ASN1 functions: this can be used to determine if old | |
834 | code will still work when these eventually go away. | |
09ab755c DSH |
835 | [Steve Henson] |
836 | ||
a9d2bc49 | 837 | +) New extension functions for OCSP structures, these follow the |
ec558b65 DSH |
838 | same conventions as certificates and CRLs. |
839 | [Steve Henson] | |
840 | ||
a9d2bc49 | 841 | +) New function X509V3_add1_i2d(). This automatically encodes and |
57d2f217 DSH |
842 | adds an extension. Its behaviour can be customised with various |
843 | flags to append, replace or delete. Various wrappers added for | |
844 | certifcates and CRLs. | |
845 | [Steve Henson] | |
846 | ||
a9d2bc49 | 847 | +) Fix to avoid calling the underlying ASN1 print routine when |
5755cab4 DSH |
848 | an extension cannot be parsed. Correct a typo in the |
849 | OCSP_SERVICELOC extension. Tidy up print OCSP format. | |
850 | [Steve Henson] | |
851 | ||
3880cd35 BM |
852 | *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c). |
853 | Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits | |
854 | when writing a 32767 byte record. | |
855 | [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>] | |
856 | ||
f640ee90 | 857 | *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c), |
126fe085 | 858 | obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}. |
f640ee90 BM |
859 | |
860 | (RSA objects have a reference count access to which is protected | |
861 | by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c], | |
862 | so they are meant to be shared between threads.) | |
126fe085 BM |
863 | [Bodo Moeller, Geoff Thorpe; original patch submitted by |
864 | "Reddie, Steven" <Steven.Reddie@ca.com>] | |
f640ee90 | 865 | |
a9d2bc49 | 866 | +) Make mkdef.pl parse some of the ASN1 macros and add apropriate |
9c67ab2f | 867 | entries for variables. |
5755cab4 | 868 | [Steve Henson] |
9c67ab2f | 869 | |
1456d186 BM |
870 | *) Fix a deadlock in CRYPTO_mem_leaks(). |
871 | [Bodo Moeller] | |
872 | ||
a9d2bc49 | 873 | +) Add functionality to apps/openssl.c for detecting locking |
3ac82faa BM |
874 | problems: As the program is single-threaded, all we have |
875 | to do is register a locking callback using an array for | |
876 | storing which locks are currently held by the program. | |
3ac82faa BM |
877 | [Bodo Moeller] |
878 | ||
a9d2bc49 | 879 | +) Use a lock around the call to CRYPTO_get_ex_new_index() in |
3ac82faa BM |
880 | SSL_get_ex_data_X509_STORE_idx(), which is used in |
881 | ssl_verify_cert_chain() and thus can be called at any time | |
882 | during TLS/SSL handshakes so that thread-safety is essential. | |
883 | Unfortunately, the ex_data design is not at all suited | |
884 | for multi-threaded use, so it probably should be abolished. | |
885 | [Bodo Moeller] | |
886 | ||
a9d2bc49 | 887 | +) Added Broadcom "ubsec" ENGINE to OpenSSL. |
2a86064f GT |
888 | [Broadcom, tweaked and integrated by Geoff Thorpe] |
889 | ||
a9d2bc49 | 890 | +) Move common extension printing code to new function |
2c15d426 | 891 | X509V3_print_extensions(). Reorganise OCSP print routines and |
c08523d8 | 892 | implement some needed OCSP ASN1 functions. Add OCSP extensions. |
2c15d426 DSH |
893 | [Steve Henson] |
894 | ||
a9d2bc49 | 895 | +) New function X509_signature_print() to remove duplication in some |
de487514 DSH |
896 | print routines. |
897 | [Steve Henson] | |
898 | ||
a9d2bc49 | 899 | +) Add a special meaning when SET OF and SEQUENCE OF flags are both |
06db4253 DSH |
900 | set (this was treated exactly the same as SET OF previously). This |
901 | is used to reorder the STACK representing the structure to match the | |
902 | encoding. This will be used to get round a problem where a PKCS7 | |
903 | structure which was signed could not be verified because the STACK | |
904 | order did not reflect the encoded order. | |
905 | [Steve Henson] | |
906 | ||
a9d2bc49 | 907 | +) Reimplement the OCSP ASN1 module using the new code. |
36f554d4 DSH |
908 | [Steve Henson] |
909 | ||
a9d2bc49 | 910 | +) Update the X509V3 code to permit the use of an ASN1_ITEM structure |
2aff7727 DSH |
911 | for its ASN1 operations. The old style function pointers still exist |
912 | for now but they will eventually go away. | |
913 | [Steve Henson] | |
914 | ||
a9d2bc49 | 915 | +) Merge in replacement ASN1 code from the ASN1 branch. This almost |
5755cab4 DSH |
916 | completely replaces the old ASN1 functionality with a table driven |
917 | encoder and decoder which interprets an ASN1_ITEM structure describing | |
918 | the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is | |
919 | largely maintained. Almost all of the old asn1_mac.h macro based ASN1 | |
920 | has also been converted to the new form. | |
9d6b1ce6 DSH |
921 | [Steve Henson] |
922 | ||
a9d2bc49 | 923 | +) Change BN_mod_exp_recp so that negative moduli are tolerated |
8dea52fa BM |
924 | (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set |
925 | so that BN_mod_exp_mont and BN_mod_exp_mont_word work | |
926 | for negative moduli. | |
927 | [Bodo Moeller] | |
928 | ||
a9d2bc49 | 929 | +) Fix BN_uadd and BN_usub: Always return non-negative results instead |
8dea52fa BM |
930 | of not touching the result's sign bit. |
931 | [Bodo Moeller] | |
932 | ||
a9d2bc49 | 933 | +) BN_div bugfix: If the result is 0, the sign (res->neg) must not be |
80d89e6a BM |
934 | set. |
935 | [Bodo Moeller] | |
936 | ||
a9d2bc49 | 937 | +) Changed the LHASH code to use prototypes for callbacks, and created |
f1919c3d GT |
938 | macros to declare and implement thin (optionally static) functions |
939 | that provide type-safety and avoid function pointer casting for the | |
940 | type-specific callbacks. | |
941 | [Geoff Thorpe] | |
942 | ||
1946cd8b UM |
943 | *) Use better test patterns in bntest. |
