After getting WSAEWOULDBLOCK, the connection is not restart because of the state WSAENOTCONN that is not known. OpenLDAP use ENOTCONN that is set to 126 by "ucrt/errno.h" while WSAENOTCONN is 10057L.

[Issue 10274] New: Replication issue on MMR configuration

We use a load balancer (VIP) to poll all of our servers equally. (but it is possible to do performance tests directly on each of the directories) With our current infrastructure we're able to perform approximately 300 MOD/BIND/s. Beyond that, we start to generate delays and can randomly come across one issue. However, when we run performance tests that exceed our write capacity, our replication between servers can randomly create an incident with directories being unable to catch up with their replication delay. The directories update their contextCSNs, but extremely slowly (like freezing). From then on, it's impossible for the directories to catch again. (even with no incoming traffic) A restart of the instance is required to perform a full refresh and solve the incident. We have enabled synchronization logs and have no error or refresh logs to indicate a problem ( we can provide you with logs if necessary). We suspect a write collision or a replication conflict but this is never write in our sync logs. We've run a lot of tests. For example, when we run a performance test on a single live server, we don't reproduce the problem. Anothers examples: if we define different accounts ranges for each server with SALMD, we don't reproduce the problem either. If we use only one account for the range, we don't reproduce the problem either. ______________________________________________________________________ I have add some screenshots on attachement to show you the issue and all the explanations. ______________________________________________________________________ *Symptoms :* One or more directories can no longer be replicated normally after performance testing ends. No apparent error logs. Need a restart of instances to solve the problem. *How to reproduce the problem:* Have at least two servers in MMR mode Set LastBind to TRUE Perform a SLAMD shot from a LoadBalancer in bandwidth mode OR start multiple SLAMD test on same time for each server with the same account range. Exceed the maximum write capacity of the servers. *SLAMD configuration :* authrate.sh --hostname ${HOSTNAME} --port ${PORTSSL} \ --useSSL --trustStorePath ${CACERTJKS} \ --trustStorePassword ${CACERTJKSPW} --bindDN "${BINDDN}" \ --bindPassword ${BINDPW} --baseDN "${BASEDN}" \ --filter "(uid=[${RANGE}])" --credentials ${USERPW} \ --warmUpIntervals ${WARMUP} \ --numThreads ${NTHREADS} ${ARGS} -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9564] New: Race condition with freeing the spilled pages from transaction
by openldap-its＠openldap.org 15 Oct '25

https://bugs.openldap.org/show_bug.cgi?id=9564 Issue ID: 9564 Summary: Race condition with freeing the spilled pages from transaction Product: LMDB Version: 0.9.29 Hardware: Other OS: Mac OS Status: UNCONFIRMED Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: kriszyp(a)gmail.com Target Milestone: --- Created attachment 825 --> https://bugs.openldap.org/attachment.cgi?id=825&action=edit Free the spilled pages and dirty overflows before unlocking the write mutex The spilled pages (a transaction's mt_spill_pgs) is freed *after* a write transaction's mutex is unlocked (in mdb.master3). This can result in a race condition where a second transaction can start and subsequently assign a new mt_spill_pgs list to the transaction structure that it reuses. If this occurs after the first transaction unlocks the mutex, but before it performs the free operation on mt_spill_pgs, then the first transaction will end up calling a free on the same spilled page list as the second transaction, resulting in a double free (and crash). It would seem to be an extremely unlikely scenario to actually happen, since the free call is literally the next operation after the mutex is unlocked, and the second transaction would need to make it all the way to the point of saving the freelist before a page spill list is likely to be allocated. Consequently, this probably has rarely happened. However, one of our users (see https://github.com/DoctorEvidence/lmdb-store/issues/48 for the discussion) has noticed this occurring, and it seems that it may be particularly likely to happen on MacOS on the new M1 silicon. Perhaps there is some peculiarity to how the threads are more likely to yield execution after a mutex unlock, I am not sure. I was able to reproduce the issue by intentionally manipulating the timing (sleeping before the free) to verify that the race condition is technically feasible, and apparently this can happen "in the wild" on MacOS, at least with an M1. It is also worth noting that this is due to (or a regression from) the fix for ITS#9155 (https://github.com/LMDB/lmdb/commit/cb256f409bb53efeda4ac69ee8165a0b4fc1a277) where the free call was moved outside the conditional (for having a parent) that had previously never been executed after the mutex is unlocked, but now is called after the unlock. Anyway, the solution is relatively simple, the free call simply has to be moved above the unlock. In my patch, I also moved the free call for mt_dirty_ovs. I am not sure what OVERFLOW_NOTYET/mt_dirty_ovs is for, but presumably it should be handled the same. This could alternately be solved by saving the reference to these lists before unlocking, and freeing after unlocking, which would slightly decrease the amount of processing within the mutex guarded code. Let me know if you prefer a patch that does that. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10313] New: 3-way multimaster oathHOTPCounter attribute update code missing

https://bugs.openldap.org/show_bug.cgi?id=10313 Issue ID: 10313 Summary: 3-way multimaster oathHOTPCounter attribute update code missing Product: OpenLDAP Version: 2.6.6 Hardware: x86_64 OS: Linux Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: agrru01(a)gmail.com Target Milestone: --- I posted on openldap technical mail list and got a response saying I should file a feature request. I am using a 3-way multimaster syncrepl setup with the slapo-otp module. My problem is that when authenticating with a user using HOTP, the attribute oathHOTPCounter only updates the value on the target ldap instance. This means the other two ldap instances do not get the updated HOTP-counter value and therefore will allow authentication using the same HOTP code. Interestingly enough, if I manually edit the oathHOTPCounter value it synchronizes with the other masters.

Here is a trace: ldap_sasl_bind ldap_send_initial_request ldap_new_connection 1 1 0 ldap_int_open_connection ldap_connect_to_host: TCP winserv.test.net:636 ldap_new_socket: 3 ldap_prepare_socket: 3 ldap_connect_to_host: Trying 192.168.56.2:636 ldap_pvt_connect: fd: 3 tm: 30 async: -1 ldap_ndelay_on: 3 attempting to connect: connect errno: 115 ldap_int_poll: fd: 3 tm: 0 ldap_err2string [2024-04-25 15:41:27.112] [error] [:1] bind(): Connecting (X) [2024-04-25 15:41:27.112] [error] [:1] err: -18 ldap_sasl_bind ldap_send_initial_request ldap_int_poll: fd: 3 tm: 0 ldap_is_sock_ready: 3 ldap_ndelay_off: 3 TLS trace: SSL_connect:before SSL initialization TLS trace: SSL_connect:SSLv3/TLS write client hello Looks like it happens because non-blocking mode is cleared from the socket (ldap_ndelay_off) after the first poll for write, and non-blocking mode is never restored before attempt to do tls connect, because of the check that assumes that non-blocking mode has already been set for async mode: if ( !async ) { /* if async, this has already been set */ ber_sockbuf_ctrl( sb, LBER_SB_OPT_SET_NONBLOCK, (void*)1 ); } while in fact it was cleared. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10379] New: lastbind change prevents ppolicy response from reaching accesslog

https://bugs.openldap.org/show_bug.cgi?id=10379 Issue ID: 10379 Summary: lastbind change prevents ppolicy response from reaching accesslog Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: ondra(a)mistotebe.net Target Milestone: --- When "lastbind on" and ppolicy are configured together, the pwdLastSuccess update triggers an accesslog entry (using op->o_time, op->o_tincr), then ppolicy_bind_response issues its own modification and since the time was copied in lastbind, an entry of the same name already exists. This means the ppolicy change is lost (and e.g. won't replicate). Note that slapo-lastbind (=the contrib overlay) probably has the same impact. -- You are receiving this mail because: You are on the CC list for the issue.
