[Issue 7165] Killing slap tools breaks the running mdb

https://bugs.openldap.org/show_bug.cgi?id=7165 --- Comment #5 from Howard Chu <hyc(a)openldap.org> --- Most of this bug appears to be obsolete. (In reply to Hallvard Furuseth from comment #0) > Full_Name: Hallvard B Furuseth > Version: master, d861910f55cb1beb5e443caa7e961ed760074352 > OS: Linux x86_64 > URL: > Submission from: (NULL) (195.1.106.125) > Submitted by: hallvard > > > Aborting an MDB process can break MDB if another MDB process is > running, because then locks/reader table info are not reset. Using mdb_stat -rr will purge stale readers. I suppose we could tweak back-mdb to also do a reader purge if it ever gets a MDB_READERS_FULL error from mdb_txn_begin. > > The problems below go away when the last slap process terminates > so the lockfile can be reset.

At this point the only potential action I see is to add a check for MDB_READERS_FULL as noted at the beginning of this reply. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9567] New: Double free error after attempt to insert a duplicate entry

https://bugs.openldap.org/show_bug.cgi?id=9567 Issue ID: 9567 Summary: Double free error after attempt to insert a duplicate entry Product: LMDB Version: 0.9.17 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: wietse(a)porcupine.org Target Milestone: --- This problem was originally discovered by Adi Prasaja on Ubuntu with lmdb-0.9.24, and reproduced by me on Fedora with lmdb-0.9.25, as well as multiple source repo branches from github.com/openldap. The problem was introduced with lmdb version 0.9.17 and still exists in the 'head' version 0.9.70 as retrieved from github.com on May 28, 2021. Quick demo (any Postfix version with LMDB support): create a key-value store from a file containing one (key, value) per line. $ cat /tmp/aa aa 1 aa 2 $ postmap lmdb:/tmp/aa postmap: warning: lmdb:/tmp/aa: duplicate entry: "aa" <== Postfix message free(): double free detected in tcache 2 <== libc message Aborted (core dumped) Commenting out the free(env->me_txn0) call mdb_env_close0() will prevent the double free() error. Of course, that results in a memory leak when the input contains no duplicate line. The remainder of this message show the steps to reproduce this with lmdb version 0.9.70 (from github 'head') on Fedora 32 with postfix-3.7-20210424. These steps have been verified to also work for Postfix 3.2.

[Issue 9564] New: Race condition with freeing the spilled pages from transaction
by openldap-its＠openldap.org 27 May '21

27 May '21

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.
