by openldap-its＠openldap.org 17 Sep '24

https://bugs.openldap.org/show_bug.cgi?id=9920 Issue ID: 9920 Summary: MDB_PAGE_FULL with master3 (encryption) because there is no room for the authentication data (MAC) Product: LMDB Version: unspecified Hardware: x86_64 OS: Mac OS Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: info(a)parlepeuple.fr Target Milestone: --- Created attachment 915 --> https://bugs.openldap.org/attachment.cgi?id=915&action=edit proposed patch Hello, on master3, using the encryption at rest feature, I am testing as follow: - on a new named database, i set the encryption function with mdb_env_set_encrypt(env, encfunc, &enckey, 32) - note that I chose to have a size parameter (The size of authentication data in bytes, if any. Set this to zero for unauthenticated encryption mechanisms.) of 32 bytes. - I add 2 entries on the DB, trying to saturate the first page. I chose to add a key of 33 Bytes and a value of 1977 Bytes, so the size of each node is 2010 Bytes (obviously the 2 keys are different). - This passes and the DB has just one leaf_pages, no overflow_pages, no branch_pages, an a depth of 1. - If I add one byte to the values I insert (starting again from a blank DB), then , instead of seeing 2 overflow_pages, I get an error : MDB_PAGE_FULL. - this clearly should not have happened. - Here is some tracing : add to leaf page 2 index 0, data size 48 key size 7 [74657374646200] add to leaf page 3 index 0, data size 1978 key size 33 [000000000000000000000000000000000000000000000000000000000000000000] add to branch page 5 index 0, data size 0 key size 0 [null] add to branch page 5 index 1, data size 0 key size 33 [000000000000000000000000000000000000000000000000000000000000000000] add to leaf page 4 index 0, data size 1978 key size 33 [000000000000000000000000000000000000000000000000000000000000000000] add to leaf page 4 index 1, data size 1978 key size 33 [020202020202020202020202020202020202020202020202020202020202020202] not enough room in page 4, got 1 ptrs upper-lower = 2020 - 2 = 2016 node size = 2020 Looking at the code, I understand that there is a problem at line 9005 : } else if (node_size + data->mv_size > mc->mc_txn->mt_env->me_nodemax) { where me_nodemax is incorrect, as it is not taking into account that some bytes will be needed for the MAC authentication code, which size is in env->me_esumsize. me_nodemax is calculated at line 5349: env->me_nodemax = (((env->me_psize - PAGEHDRSZ ) / MDB_MINKEYS) & -2) - sizeof(indx_t); So I substract me_esumsize with a "- env->me_esumsize" here: env->me_nodemax = (((env->me_psize - PAGEHDRSZ - env->me_esumsize) / MDB_MINKEYS) & -2) - sizeof(indx_t); I also substract it from me_maxfree_1pg in the line above, and in pmax in line 10435. I do not know if my patch is correct, but it solves the issue. Maybe there are other places in the code where the me_esumsize should be substracted from the available size. By example, when calculating the number of overflow pages in OVPAGES, it does not take into account me_esumsize, but I think it is ok, because there is only one MAC for the entire set of OV pages, and there is room for it in the first OV page. See the attached proposed patch. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 7981] Feature request: Crypt scheme in pwdPolicy

https://bugs.openldap.org/show_bug.cgi?id=7981 Howard Chu <hyc(a)openldap.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Ever confirmed|0 |1 Status|UNCONFIRMED |CONFIRMED --- Comment #4 from Howard Chu <hyc(a)openldap.org> --- We can't simply add this to the pwdPolicy objectclass since that is a standardized class. Also the values of crypt schemes are server specific, not standardized at all. A solution for us would be to define an OpenLDAP-specific subclass of the pwdPolicy class, and add whatever we need to in there and use it going forward. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10217] New: autoca should support more key types

[Issue 9813] New: Incompatibility between remoteauth and ppolicy overlays
by openldap-its＠openldap.org 17 Sep '24

https://bugs.openldap.org/show_bug.cgi?id=9813 Issue ID: 9813 Summary: Incompatibility between remoteauth and ppolicy overlays Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: thierry.pubellier(a)paris.fr Target Milestone: --- Hi, We are planning to use OpenLDAP as a proxy for some users in our Active Directory servers, using remoteauth overlay. We want this OpenLDAP instance to also implement an account lockout policy, preventing the lockout on our internal Active Directory servers. But there seems to be an incompatibility between remoteauth and ppolicy overlays : remoteauth won't remote authenticate a user if local userPassword attribute exists, while ppolicy overlay needs this attribute. Could there be a configuration parameter in ppolicy to allow lockout checks/modifications (which seemed to be the default behavior of OpenLDAP before ITS#7089) ? I can provide a patch if allowed. Thanks by advance, Best regards, Thierry -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9343] New: Expand ppolicy policy configuration to allow URL filter
by openldap-its＠openldap.org 17 Sep '24

17 Sep '24

https://bugs.openldap.org/show_bug.cgi?id=9343 Issue ID: 9343 Summary: Expand ppolicy policy configuration to allow URL filter Product: OpenLDAP Version: 2.5 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: quanah(a)openldap.org Target Milestone: --- Currently, ppolicy only supports a single global default policy, and past that any policies must be manually added to a given user entry if they are supposed to have something other than the default policy. Also, some sites want no default policy, and only a specific subset to have a policy applied to them. For both of these cases, it would be helpful if it were possible to configure a policy to apply to a set of users via a URL similar to the way we handle creating groups of users in dynlist -- You are receiving this mail because: You are on the CC list for the issue.

https://bugs.openldap.org/show_bug.cgi?id=8476 --- Comment #2 from Quanah Gibson-Mount <quanah(a)openldap.org> --- Seems like a good idea.
