Looking at your logs, it's clear that the error occurs and connection_closing() is called, which will call connection_abandon() to set the o_abandon flag on all of the connection's ops. Can you please provide the output for "print *op" and "print *op->o_hdr" in thread 13 and thread 16, frame 3? -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

Let’s just restrict ourselves to something you presumably *are* interested in: fixing this showstopper bug which locks up your entire server if just a few client TCP connections fail in a particular way. I will be happy to provide more information on reproducing the problem, if you need it. In case you hadn't noticed, I've been investigating and trying to help you.

slapd deadlock bug ITS#7296
by Richard Silverman 21 Dec '12

21 Dec '12

Hello, I’m working on this bug: http://www.openldap.org/lists/openldap-bugs/201206/msg00026.html If slapd client connections are torn down in mid-query -- the server has received the query and has a pending reply to send, but the connection is closed by the client before it can be sent -- this deadlocks slapd worker threads. Eventually all threads are deadlocked in send_ldap_ber() which serializes their network access to send PDUs, and the server becomes unresponsive and has to be killed. send_ldap_ber() notices the connection drop and calls connection_closing(). The problem appears to be that then connection_abandon() abandons all outstanding executing ops, but does not empty the c_ops queue (as it does with c_pending_ops). When connection_close() looks at the connection, it always sees there are outstanding ops and defers the close. I see this pattern: 50cb3104 connection_closing: readying conn=1519 sd=33 for close 50cb3104 connection_close: deferring conn=1519 sd=33 50cb3104 connection_resched: attempting closing conn=1519 sd=33 50cb3104 connection_close: deferring conn=1519 sd=33 50cb3104 connection_resched: attempting closing conn=1519 sd=33 ... which repeats until the server freezes entirely. If I add code to connection_abandon() to empty c_ops, it causes slapd to crash later with a mutex usage error, so that's apparently not the right place/way to do it. If I note that the connection is dying and have connection_destroy() skip the assertion that c_ops must be empty, it fixes the bug: the deadlock no longer occurs. However, I'm concerned this will leak memory as the ops aren't being freed. So my question is: what's the right way to get the outstanding executing ops abandoned by connection_abandon() to be freed? The code is complex and I may have misunderstood how best to go about fixing this, but hopefully this is enough to make sense. Thanks, -- Richard E. Silverman

make check: slapd-bind PID=10702: ldap_sasl_bind_s: Invalid credentials (49)

Hi, When running 'make check' of openldap-2.4.33, I get a lot of these type of errors: "slapd-bind PID=10702: ldap_sasl_bind_s: Invalid credentials (49)" for test 'test008-concurrency'. I have build openldap with '--with-cyrus-sasl'. Could something be wrong with the test script, or is there something wrong with my build ?

The circular dependencies are much like > the single-page case, but worse. Maybe look into this in the > future, but it's not absolutely necessary now. Suggestions to reduce freelist changes during commit: Let a freelist entry steal page numbers listed in the next entries. Then mdb_page_alloc can grab more old pages without deleting/updating their entries and producing new dirty pages. Next txn does the updates. Preallocate the final MDB_oldpages with MDB_RESERVE in mdb_txn_commit() and leave some room to spare. Then use page numbers from it and/or steal new ones at need. BTW, could MDB offer an MDB_RESERVE2 which says "give me data->mv_size bytes plus as much more as will fit without growing the page"? And MDB_RESERVE2_SHRINK which shrinks the size to the final size. Stolen pages -- one way would be to search for particular pages to seal, and list the stolen ones at the end of the freelist entry. Or: Stealing only from the end of the previous entry/entries should be simpler, but doesn't let us choose some specific pages to steal in order to gain a big enough contiguous page range: typedef struct MDB_freelist_entry { /* freelist entry in the DB */ short mf_len; /* saved length */ short mf_stolen_entries; /* #fully stolen entries */ short mf_nextlen; /* 0 or remaining length of next entry */ MDB_ID mf_pages[]; /* length mf_len. */ } MDB_freelist_entry; Thus, if the free DB contains (txnid_t)123 => { .mf_stolen_entries = 1, .mf_nextlen = 7 } (txnid_t)124 => { ... } (txnid_t)125 => { .mf_len = 20 } then mdb should henceforth skip entry#124 and entry#125.mf_pages[7..19]. A simple variant of page ranges, to save space and simplify range handling: /* Page range: (pagecount << MDB_PGNO_BITS) | (pageno + pagecount) */ typedef pgno_t mdb_pages_t; Lone pages get pagecount=1. With MDB_PGCOUNT_BITS = (64bit 4 ? 19 : 12) and page size 4096, that limits MDB to a 128 petabyte DB and 2G entry size. Or 4G database and 16M entry size on 32-bit machines. (I'd call limiting the entry size a bonus compared to today's mdb: The current freelist doesn't exactly handle 2 billion freed pages gracefully.) -- Hallvard

indexing optimization
by Howard Chu 04 Dec '12

04 Dec '12

In schema_init.c hashPreset() we compute the initial value of the index hash. This includes a prefix string which is usually the attribute's canonical name, a prefix character which is 0 or a particular substring index type, and then the syntax OID and matching rule OID. This is computed once per attribute. We could instead compute this one-time only, and save the result in the Attribute structure, or the AttributeDescription structure. (It probably makes most sense in the latter, since the prefix also may include any tags on the attributeDescription.) This change would require changing the signature of the indexer functions, to pass in the AttrDesc pointer or something to convey the precomputed hash. Or we could do away with some of this. Hashing against the syntax and mr OID seems gratuitous, since the index values are already going to be segregated by prefix and pre. One way or another, the hash over these two OIDs should be factored out, because even if we want to keep them, they're constants and we shouldn't need to keep recomputing them. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/
