4 | Changes between 0.9.6 and 0.9.7 [xx XXX 2000] |
5 | ||
ec5add87 DSH |
6 | *) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new |
7 | ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN | |
8 | uses the special reorder version of SET OF to sort the attributes | |
9 | and reorder them to match the encoded order. This resolves a long | |
10 | standing problem: a verify on a PKCS7 structure just after signing | |
11 | it used to fail because the attribute order did not match the | |
12 | encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes: | |
13 | it uses the received order. This is necessary to tolerate some broken | |
14 | software that does not order SET OF. This is handled by encoding | |
15 | as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class) | |
16 | to produce the required SET OF. | |
17 | [Steve Henson] | |
18 | ||
a6574c21 RL |
19 | *) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and |
20 | OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header | |
21 | files to get correct declarations of the ASN.1 item variables. | |
22 | [Richard Levitte] | |
23 | ||
ecbe0781 DSH |
24 | *) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many |
25 | PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs: | |
26 | asn1_check_tlen() would sometimes attempt to use 'ctx' when it was | |
27 | NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i(). | |
28 | New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant | |
29 | ASN1_ITEM and no wrapper functions. | |
30 | [Steve Henson] | |
31 | ||
4e1209eb DSH |
32 | *) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These |
33 | replace the old function pointer based I/O routines. Change most of | |
34 | the *_d2i_bio() and *_d2i_fp() functions to use these. | |
35 | [Steve Henson] | |
36 | ||
3f07fe09 RL |
37 | *) Enhance mkdef.pl to be more accepting about spacing in C preprocessor |
38 | lines, recognice more "algorithms" that can be deselected, and make | |
39 | it complain about algorithm deselection that isn't recognised. | |
40 | [Richard Levitte] | |
41 | ||
78d3b819 | 42 | *) New ASN1 functions to handle dup, sign, verify, digest, pack and |
73e92de5 DSH |
43 | unpack operations in terms of ASN1_ITEM. Modify existing wrappers |
44 | to use new functions. Add NO_ASN1_OLD which can be set to remove | |
45 | some old style ASN1 functions: this can be used to determine if old | |
46 | code will still work when these eventually go away. | |
09ab755c DSH |
47 | [Steve Henson] |
48 | ||
ec558b65 DSH |
49 | *) New extension functions for OCSP structures, these follow the |
50 | same conventions as certificates and CRLs. | |
51 | [Steve Henson] | |
52 | ||
57d2f217 DSH |
53 | *) New function X509V3_add1_i2d(). This automatically encodes and |
54 | adds an extension. Its behaviour can be customised with various | |
55 | flags to append, replace or delete. Various wrappers added for | |
56 | certifcates and CRLs. | |
57 | [Steve Henson] | |
58 | ||
5755cab4 DSH |
59 | *) Fix to avoid calling the underlying ASN1 print routine when |
60 | an extension cannot be parsed. Correct a typo in the | |
61 | OCSP_SERVICELOC extension. Tidy up print OCSP format. | |
62 | [Steve Henson] | |
63 | ||
3880cd35 BM |
64 | *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c). |
65 | Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits | |
66 | when writing a 32767 byte record. | |
67 | [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>] | |
68 | ||
f640ee90 | 69 | *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c), |
126fe085 | 70 | obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}. |
f640ee90 BM |
71 | |
72 | (RSA objects have a reference count access to which is protected | |
73 | by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c], | |
74 | so they are meant to be shared between threads.) | |
126fe085 BM |
75 | [Bodo Moeller, Geoff Thorpe; original patch submitted by |
76 | "Reddie, Steven" <Steven.Reddie@ca.com>] | |
f640ee90 | 77 | |
9c67ab2f DSH |
78 | *) Make mkdef.pl parse some of the ASN1 macros and add apropriate |
79 | entries for variables. | |
5755cab4 | 80 | [Steve Henson] |
9c67ab2f | 81 | |
1456d186 BM |
82 | *) Fix a deadlock in CRYPTO_mem_leaks(). |
83 | [Bodo Moeller] | |
84 | ||
3ac82faa BM |
85 | *) Add functionality to apps/openssl.c for detecting locking |
86 | problems: As the program is single-threaded, all we have | |
87 | to do is register a locking callback using an array for | |
88 | storing which locks are currently held by the program. | |
3ac82faa BM |
89 | [Bodo Moeller] |
90 | ||
91 | *) Use a lock around the call to CRYPTO_get_ex_new_index() in | |
92 | SSL_get_ex_data_X509_STORE_idx(), which is used in | |
93 | ssl_verify_cert_chain() and thus can be called at any time | |
94 | during TLS/SSL handshakes so that thread-safety is essential. | |
95 | Unfortunately, the ex_data design is not at all suited | |
96 | for multi-threaded use, so it probably should be abolished. | |
97 | [Bodo Moeller] | |
98 | ||
2a86064f GT |
99 | *) Added Broadcom "ubsec" ENGINE to OpenSSL. |
100 | [Broadcom, tweaked and integrated by Geoff Thorpe] | |
101 | ||
2c15d426 DSH |
102 | *) Move common extension printing code to new function |
103 | X509V3_print_extensions(). Reorganise OCSP print routines and | |
c08523d8 | 104 | implement some needed OCSP ASN1 functions. Add OCSP extensions. |
2c15d426 DSH |
105 | [Steve Henson] |
106 | ||
de487514 DSH |
107 | *) New function X509_signature_print() to remove duplication in some |
108 | print routines. | |
109 | [Steve Henson] | |
110 | ||
06db4253 DSH |
111 | *) Add a special meaning when SET OF and SEQUENCE OF flags are both |
112 | set (this was treated exactly the same as SET OF previously). This | |
113 | is used to reorder the STACK representing the structure to match the | |
114 | encoding. This will be used to get round a problem where a PKCS7 | |
115 | structure which was signed could not be verified because the STACK | |
116 | order did not reflect the encoded order. | |
117 | [Steve Henson] | |
118 | ||
36f554d4 DSH |
119 | *) Reimplement the OCSP ASN1 module using the new code. |
120 | [Steve Henson] | |
121 | ||
2aff7727 DSH |
122 | *) Update the X509V3 code to permit the use of an ASN1_ITEM structure |
123 | for its ASN1 operations. The old style function pointers still exist | |
124 | for now but they will eventually go away. | |
125 | [Steve Henson] | |
126 | ||
9d6b1ce6 | 127 | *) Merge in replacement ASN1 code from the ASN1 branch. This almost |
5755cab4 DSH |
128 | completely replaces the old ASN1 functionality with a table driven |
129 | encoder and decoder which interprets an ASN1_ITEM structure describing | |
130 | the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is | |
131 | largely maintained. Almost all of the old asn1_mac.h macro based ASN1 | |
132 | has also been converted to the new form. | |
9d6b1ce6 DSH |
133 | [Steve Henson] |
134 | ||
8dea52fa BM |
135 | *) Change BN_mod_exp_recp so that negative moduli are tolerated |
136 | (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set | |
137 | so that BN_mod_exp_mont and BN_mod_exp_mont_word work | |
138 | for negative moduli. | |
139 | [Bodo Moeller] | |
140 | ||
141 | *) Fix BN_uadd and BN_usub: Always return non-negative results instead | |
142 | of not touching the result's sign bit. | |
143 | [Bodo Moeller] | |
144 | ||
80d89e6a BM |
145 | *) BN_div bugfix: If the result is 0, the sign (res->neg) must not be |
146 | set. | |
147 | [Bodo Moeller] | |
148 | ||
f1919c3d GT |
149 | *) Changed the LHASH code to use prototypes for callbacks, and created |
150 | macros to declare and implement thin (optionally static) functions | |
151 | that provide type-safety and avoid function pointer casting for the | |
152 | type-specific callbacks. | |
153 | [Geoff Thorpe] | |
154 | ||
1946cd8b UM |
155 | *) Use better test patterns in bntest. |
156 |
