(ITS#8239) back-meta crashes after deleting a rewrite rule
by ryan＠openldap.org 07 Sep '15

07 Sep '15

Full_Name: Ryan Tandy Version: master OS: Debian URL: Submission from: (NULL) (24.68.37.4) Submitted by: ryan Deleting rewrite rules from a back-meta target is not implemented correctly. Deleting a single value (vs the entire attribute) isn't checked for, the entire rewrite_info and list of saved rules is always freed. Then meta_back_conn_destroy doesn't notice the rewrite_session has already been cleaned up, and tries to free it again.

It seems to me that this happens with the rule most recently inserted. If slapd was recently restarted, this would be the last rule in the list. The parsing rules are slightly different for slapd.conf vs ldif. Notable is that ldif parsing does not perform escape processing. So this slapd.conf line: rwm-rewriteRule "(.*\$)uid=sapr3(\$.*)" "$1uid=dlmsapr3$2" should actually correspond to this cn=config attribute: olcRwmRewrite: rwm-rewriteRule "(.*$)uid=sapr3($.*)" "$1uid=dlmsapr3$2" This is exactly the output of conversion with, for example, slaptest -f slapd.conf -F slapd.d. When a new rwm rule is added, existing rules are reloaded. The bug is that the existing rules were being passed through the slapd.conf line processor, which dropped backslashes on the way, while the rule actually being inserted was passed to the rewrite routines untouched. Fixed in git master by removing the extra escaping on insert. You will have to adjust your rules to use a single backslash instead of two. (bonus: rwm is needlessly reloading existing rules when appending with valx >= last, while it could be

Re: (ITS#8230) [new PATCHes] totp: bug fixes and improvements

Hi, Please have a look at the improved patch series in https://github.com/marschap/openldap/commits/contrib-totp3 and https://github.com/marschap/openldap/commits/contrib-totp4 They try to address the issues in the previous versions Changes: * contrib/passwd/totp: fix the big-endian case, support 32-bit archs Use memcpy for the WORDS_BIGENDIAN case [much simpler] Use uint64_t for same results in 32- and 64-bit cases * contrib/passwd/totp: support compiling using nettle Fix the botched previous patch. The two branches differ only in that patch, giving the following alternatives: - contrib-totp3 continues to use the HMAC_... macros It still requires the #if...#else...#endif to harmonize the setup in do_hmac() - contrib-totp4 gets rid of the HMAC_... macros It uses the different implementations directly in do_hmac() Of course separated by #if...#else..#endif Functionally both patches are equivalent: in my tests they yield the same results for OpenSSL and GnuTLS.

Re: (ITS#7889) rwm overlay causes incorrect acl parsing

michael(a)stroeder.com wrote: >But could you please check whether this setting helps: > >rwm-drop-unrequested-attrs no It does. This is another case of ITS#6057; the ACL filter can only be evaluated if the filter attribute is included in those passed through by rwm, otherwise it is just skipped. The larger issue (should ACL evaluation assume the whole entry is available?) seems to still be unaddressed. I don't understand yet why rwm filters the attributes on its own by default, but I'm sure there's a reason. alexoz66(a)gmail.com wrote: >modifying entry "olcOverlay={0}rwm,olcDatabase={1}mdb,cn=config" >ldap_modify: Object class violation (65) > additional info: attribute 'olcRwmDropUnrequested' not allowed > >Looking at the schema it seems that the attribute olcRwmDropUnrequested >is not part of the olcRwmConfig object class (or any other object class >for that matter).

Hi, Please have a look at the improved patch series in https://github.com/marschap/openldap/commits/contrib-totp2 It tries to address all the issues highlighted on the first version. https://github.com/marschap/openldap/commit/e4e1045f59368af8d15172ad22fcc0f… contrib/passwd/totp: flexibilize decoding In function totp_b32_pton() - allow lowercase characters in encoded string too - allow padding to be omitted (totally, not only parts) With this added flexibility we can make use of keys encoded by other Base32-encoding implementations. In function chk_totp() determine the space required to hold the decoded key by calling totp_b32_pton() with a NULL argument for the target. Changes to previous version: - toupper()'s argument guarded with a cast to (unsigned char) - added rationale to commit message https://github.com/marschap/openldap/commit/edfa2b0fb3238ca9f231fa75bd452b4… contrib/passwd/totp: fix the big-endian case, support 32-bit archs - reverse tval in the WORDS_BIGENDIAN case before converting it to a string - use uint64_t for tval to have it correctly sized on 32-bit archs too - avoid magic number when converting tval to a string Changes to previous version: - complete rewrite https://github.com/marschap/openldap/commit/24007f02cebb0b7f801288b02d0ac8c… contrib/passwd/totp: fix decoding when padding is used In totp_b32_pton(), correctly count the number of '=' padding chars at the end of the base-32 encoded string: don't count the first padding char char twice. Note: '*str++' evaluates *str first and increases str later! Changes to previous version: - commit message only https://github.com/marschap/openldap/commit/435619ccd8be1b62f86db67643bca77… contrib/passwd/totp: support compiling using nettle Changes to previous version: - rewrite, concentrating the #ifdef's as much as possible Best Peter -- Peter Marschall peter(a)adpm.de
