https://bugs.openldap.org/show_bug.cgi?id=9305 Issue ID: 9305 Summary: ldap_connect_to_host: Return code from getaddrinfo() discarded, troubleshooting difficult Product: OpenLDAP Version: 2.4.46 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: client tools Assignee: bugs(a)openldap.org Reporter: minfrin(a)sharp.fm Target Milestone: --- When the ldap_connect_to_host() function sees a failure from getaddrinfo(), the meaningless return code -1 is returned. This makes troubleshooting difficult on a webserver, where the low level printf debugging is not practical.

[Issue 9920] New: MDB_PAGE_FULL with master3 (encryption) because there is no room for the authentication data (MAC)

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.

Thus it would be nice if cn=monitor provides more metrics. 1. Overall connection count per listener starting at 0 when started. This would be a simple counter added to: entries cn=Listener 0,cn=Listeners,cn=Monitor 2. Counter for the various "deferring" messages separated by the reason for deferring. 3. Counters for all possible result codes. In my mtail program I also label it with the result type. -- You are receiving this mail because: You are on the CC list for the bug.

It seems that shared library destructors are always called before functions registered with atexit(). A solution may be to modify libraries/libldap/init.c to use atexit() instead of "__attribute__ ((destructor))". atexit() manual page says: "Since glibc 2.2.3, atexit() can be used within a shared library to establish functions that are called when the shared library is unloaded.". Functions registered with atexit() are called in the reverse order of their registration, so libssl must by initialized before libldap. If the order is wrong, libldap should detect it somehow and exit with abort(). -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9796] New: Deprecate GnuTLS support

https://bugs.openldap.org/show_bug.cgi?id=9796 Issue ID: 9796 Summary: Deprecate GnuTLS support Product: OpenLDAP Version: 2.6.1 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: libraries Assignee: bugs(a)openldap.org Reporter: quanah(a)openldap.org Target Milestone: --- Support for GnuTLS was added specifically for the Debian (and thus Ubuntu) due to the license objections at the time that the Debian project had for the OpenSSL license. Since that time, Debian has reclassified OpenSSL as a core library and the OpenSSL project has resolved the original complaint by licensing OpenSSL 3 and later under the Apache License v2. Thus there is no longer a reason to maintain support for GnuTLS and given the long standing concerns over the security and quality of the GnuTLS bridge in addition to the extra cost of maintaining that code, it should be marked as deprecated and removed in a future release. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10219] New: Modify of olcDisabled by removing and adding a value invokes db_open twice

This means that currently a modify operation that removes a olcDisabled value will invoke the db_open handler for that database, even if in the same modify operation a value of TRUE is added. A modify operation like this: dn: olcDatabase={1}asyncmeta,cn=config changetype: modify delete: olcDisabled olcDisabled: FALSE - add: olcDisabled olcDisabled: TRUE - will call both db_open and db_close. This could be potentially harmful if the backend type allocates memory on db_open like asyncmeta, for example. It is a rare case, but it is best to fix it just in case. -- You are receiving this mail because: You are on the CC list for the issue.
