c5e8580e RL |
4 | Changes between 0.9.6 and 0.9.7 [xx XXX 2000] |
5 | ||
673b3fde BM |
6 | *) New SSLeay_version code SSLEAY_DIR to determine the compiled-in |
7 | value of OPENSSLDIR. This is available via the new '-d' option | |
8 | to 'openssl version', and is also included in 'openssl version -a'. | |
9 | [Bodo Moeller] | |
10 | ||
c06648f7 BM |
11 | *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn |
12 | call failed, free the DSA structure. | |
13 | [Bodo Moeller] | |
14 | ||
65a22e8e RL |
15 | *) Add another call level for memory allocation routines, thereby |
16 | allowing memory allocation callbacks that can be given file | |
17 | name and line number information. The basic functionality | |
18 | remains, as well as the original possibility to just replace | |
19 | malloc(), realloc() and free(). The new functions that can be | |
20 | registered help users provide variants of malloc(), realloc() | |
21 | and free() that take two extra arguments, a const char* and an | |
22 | int. To register and find out the current settings for those | |
23 | hooks, the following functions are provided: | |
24 | ||
25 | CRYPTO_set_mem_ex_functions | |
26 | CRYPTO_set_locked_mem_ex_functions | |
27 | CRYPTO_get_mem_ex_functions | |
28 | CRYPTO_get_locked_mem_ex_functions | |
29 | ||
30 | They work the same way as the corresponding CRYPTO_set_mem_functions | |
31 | and friends with one exception: giving NULL as arguments will restore | |
32 | the internal hooks to internal routines and will still make the above | |
33 | functions return 1 and not 0. | |
34 | ||
35 | This functionality was created as a direct request to add the | |
36 | possibility to interface with the Windows debugging routines | |
37 | _malloc_dbg, _realloc_dbg and _free_dbg. | |
38 | [Richard Levitte] | |
39 | ||
cbf0f45f DSH |
40 | *) Fix to uni2asc() to cope with zero length Unicode strings. |
41 | These are present in some PKCS#12 files. | |
42 | [Steve Henson] | |
43 | ||
3c914840 GT |
44 | *) Finish off removing the remaining LHASH function pointer casts. |
45 | There should no longer be any prototype-casting required when using | |
56a67adb GT |
46 | the LHASH abstraction, and any casts that remain are "bugs". See |
47 | the callback types and macros at the head of lhash.h for details | |
48 | (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example). | |
3c914840 GT |
49 | [Geoff Thorpe] |
50 | ||
599c0353 LJ |
51 | *) Add automatic query of EGD sockets in RAND_poll() for the unix variant. |
52 | If an EGD or PRNGD is running and enough entropy is returned, automatic | |
53 | seeding like with /dev/[u]random will be performed. | |
54 | Positions tried are: /etc/entropy, /var/run/egd-pool. | |
55 | [Lutz Jaenicke] | |
56 | ||
0c61e299 RL |
57 | *) Change the Unix RAND_poll() variant to be able to poll several |
58 | random devices and only read data for a small fragment of time | |
59 | to avoid hangs. Also separate out the Unix variant to it's own | |
60 | file, rand_unix.c. For VMS, there's a currently-empty rand_vms.c. | |
61 | [Richard Levitte] | |
62 | ||
0b33bc65 DSH |
63 | *) Move OCSP client related routines to ocsp_cl.c. These |
64 | provide utility functions which an application needing | |
65 | to issue a request to an OCSP responder and analyse the | |
66 | response will typically need: as opposed to those which an | |
67 | OCSP responder itself would need which will be added later. | |
68 | ||
69 | OCSP_request_sign() signs an OCSP request with an API similar | |
70 | to PKCS7_sign(). OCSP_response_status() returns status of OCSP | |
71 | response. OCSP_response_get1_basic() extracts basic response | |
72 | from response. OCSP_resp_find_status(): finds and extracts status | |
73 | information from an OCSP_CERTID structure (which will be created | |
74 | when the request structure is built). These are built from lower | |
75 | level functions which work on OCSP_SINGLERESP structures but | |
76 | wont normally be used unless the application wishes to examine | |
77 | extensions in the OCSP response for example. | |
78 | ||
79 | Replace nonce routines with a pair of functions. | |
80 | OCSP_request_add1_nonce() adds a nonce value and optionally | |
81 | generates a random value. OCSP_check_nonce() checks the | |
82 | validity of the nonce in an OCSP response. | |
83 | [Steve Henson] | |
84 | ||
85 | *) Change function OCSP_request_add() to OCSP_request_add0_id(). | |
8e961835 DSH |
86 | This doesn't copy the supplied OCSP_CERTID and avoids the |
87 | need to free up the newly created id. Change return type | |
88 | to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure. | |
89 | This can then be used to add extensions to the request. | |
90 | Deleted OCSP_request_new(), since most of its functionality | |
91 | is now in OCSP_REQUEST_new() (and the case insensitive name | |
92 | clash) apart from the ability to set the request name which | |
93 | will be added elsewhere. | |
94 | [Steve Henson] | |
95 | ||
bf0d176e DSH |
96 | *) Update OCSP API. Remove obsolete extensions argument from |
97 | various functions. Extensions are now handled using the new | |
98 | OCSP extension code. New simple OCSP HTTP function which | |
99 | can be used to send requests and parse the response. | |
100 | [Steve Henson] | |
101 | ||
ec5add87 DSH |
102 | *) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new |
103 | ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN | |
104 | uses the special reorder version of SET OF to sort the attributes | |
105 | and reorder them to match the encoded order. This resolves a long | |
106 | standing problem: a verify on a PKCS7 structure just after signing | |
107 | it used to fail because the attribute order did not match the | |
108 | encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes: | |
109 | it uses the received order. This is necessary to tolerate some broken | |
110 | software that does not order SET OF. This is handled by encoding | |
111 | as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class) | |
112 | to produce the required SET OF. | |
113 | [Steve Henson] | |
114 | ||
a6574c21 RL |
115 | *) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and |
116 | OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header | |
117 | files to get correct declarations of the ASN.1 item variables. | |
118 | [Richard Levitte] | |
119 | ||
ecbe0781 DSH |
120 | *) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many |
121 | PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs: | |
122 | asn1_check_tlen() would sometimes attempt to use 'ctx' when it was | |
123 | NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i(). | |
124 | New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant | |
125 | ASN1_ITEM and no wrapper functions. | |
126 | [Steve Henson] | |
127 | ||
4e1209eb DSH |
128 | *) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These |
129 | replace the old function pointer based I/O routines. Change most of | |
130 | the *_d2i_bio() and *_d2i_fp() functions to use these. | |
131 | [Steve Henson] | |
132 | ||
3f07fe09 RL |
133 | *) Enhance mkdef.pl to be more accepting about spacing in C preprocessor |
134 | lines, recognice more "algorithms" that can be deselected, and make | |
135 | it complain about algorithm deselection that isn't recognised. | |
136 | [Richard Levitte] | |
137 | ||
78d3b819 | 138 | *) New ASN1 functions to handle dup, sign, verify, digest, pack and |
73e92de5 DSH |
139 | unpack operations in terms of ASN1_ITEM. Modify existing wrappers |
140 | to use new functions. Add NO_ASN1_OLD which can be set to remove | |
141 | some old style ASN1 functions: this can be used to determine if old | |
142 | code will still work when these eventually go away. | |
09ab755c DSH |
143 | [Steve Henson] |
144 | ||
ec558b65 DSH |
145 | *) New extension functions for OCSP structures, these follow the |
146 | same conventions as certificates and CRLs. | |
147 | [Steve Henson] | |
148 | ||
57d2f217 DSH |
149 | *) New function X509V3_add1_i2d(). This automatically encodes and |
150 | adds an extension. Its behaviour can be customised with various | |
151 | flags to append, replace or delete. Various wrappers added for | |
152 | certifcates and CRLs. | |
153 | [Steve Henson] | |
154 | ||
5755cab4 DSH |
155 | *) Fix to avoid calling the underlying ASN1 print routine when |
156 | an extension cannot be parsed. Correct a typo in the | |
157 | OCSP_SERVICELOC extension. Tidy up print OCSP format. | |
158 | [Steve Henson] | |
159 | ||
3880cd35 BM |
160 | *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c). |
161 | Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits | |
162 | when writing a 32767 byte record. | |
163 | [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>] | |
164 | ||
f640ee90 | 165 | *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c), |
126fe085 | 166 | obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}. |
f640ee90 BM |
167 | |
168 | (RSA objects have a reference count access to which is protected | |
169 | by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c], | |
170 | so they are meant to be shared between threads.) | |
126fe085 BM |
171 | [Bodo Moeller, Geoff Thorpe; original patch submitted by |
172 | "Reddie, Steven" <Steven.Reddie@ca.com>] | |
f640ee90 | 173 | |
9c67ab2f DSH |
174 | *) Make mkdef.pl parse some of the ASN1 macros and add apropriate |
175 | entries for variables. | |
5755cab4 | 176 | [Steve Henson] |
9c67ab2f | 177 | |
1456d186 BM |
178 | *) Fix a deadlock in CRYPTO_mem_leaks(). |
179 | [Bodo Moeller] | |
180 | ||
3ac82faa BM |
181 | *) Add functionality to apps/openssl.c for detecting locking |
182 | problems: As the program is single-threaded, all we have | |
183 | to do is register a locking callback using an array for | |
184 | storing which locks are currently held by the program. | |
3ac82faa BM |
185 | [Bodo Moeller] |
186 | ||
187 | *) Use a lock around the call to CRYPTO_get_ex_new_index() in | |
188 | SSL_get_ex_data_X509_STORE_idx(), which is used in | |
189 | ssl_verify_cert_chain() and thus can be called at any time | |
190 | during TLS/SSL handshakes so that thread-safety is essential. | |
191 | Unfortunately, the ex_data design is not at all suited | |
192 | for multi-threaded use, so it probably should be abolished. | |
193 | [Bodo Moeller] | |
194 | ||
2a86064f GT |
195 | *) Added Broadcom "ubsec" ENGINE to OpenSSL. |
196 | [Broadcom, tweaked and integrated by Geoff Thorpe] | |
197 | ||
2c15d426 DSH |
198 | *) Move common extension printing code to new function |
199 | X509V3_print_extensions(). Reorganise OCSP print routines and | |
c08523d8 | 200 | implement some needed OCSP ASN1 functions. Add OCSP extensions. |
2c15d426 DSH |
201 | [Steve Henson] |
202 | ||
de487514 DSH |
203 | *) New function X509_signature_print() to remove duplication in some |
204 | print routines. | |
205 | [Steve Henson] | |
206 | ||
06db4253 DSH |
207 | *) Add a special meaning when SET OF and SEQUENCE OF flags are both |
208 | set (this was treated exactly the same as SET OF previously). This | |
209 | is used to reorder the STACK representing the structure to match the | |
210 | encoding. This will be used to get round a problem where a PKCS7 | |
211 | structure which was signed could not be verified because the STACK | |
212 | order did not reflect the encoded order. | |
213 | [Steve Henson] | |
214 | ||
36f554d4 DSH |
215 | *) Reimplement the OCSP ASN1 module using the new code. |
216 | [Steve Henson] | |
217 | ||
2aff7727 DSH |
218 | *) Update the X509V3 code to permit the use of an ASN1_ITEM structure |
219 | for its ASN1 operations. The old style function pointers still exist | |
220 | for now but they will eventually go away. | |
221 | [Steve Henson] | |
222 | ||
9d6b1ce6 | 223 | *) Merge in replacement ASN1 code from the ASN1 branch. This almost |
5755cab4 DSH |
224 | completely replaces the old ASN1 functionality with a table driven |
225 | encoder and decoder which interprets an ASN1_ITEM structure describing | |
226 | the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is | |
227 | largely maintained. Almost all of the old asn1_mac.h macro based ASN1 | |
228 | has also been converted to the new form. | |
9d6b1ce6 DSH |
229 | [Steve Henson] |
230 | ||
8dea52fa BM |
231 | *) Change BN_mod_exp_recp so that negative moduli are tolerated |
232 | (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set | |
233 | so that BN_mod_exp_mont and BN_mod_exp_mont_word work | |
234 | for negative moduli. | |
235 | [Bodo Moeller] | |
236 | ||
237 | *) Fix BN_uadd and BN_usub: Always return non-negative results instead | |
238 | of not touching the result's sign bit. | |
239 | [Bodo Moeller] | |
240 | ||
80d89e6a BM |
241 | *) BN_div bugfix: If the result is 0, the sign (res->neg) must not be |
242 | set. | |
243 | [Bodo Moeller] | |
244 | ||
f1919c3d GT |
245 | *) Changed the LHASH code to use prototypes for callbacks, and created |
246 | macros to declare and implement thin (optionally static) functions | |
247 | that provide type-safety and avoid function pointer casting for the | |
248 | type-specific callbacks. | |
249 | [Geoff Thorpe] | |
250 | ||
1946cd8b UM |
251 | *) Use better test patterns in bntest. |
252 |
