(ITS#6096) 2.4.16 replica segfault

07 May '09

Full_Name: Luca Scamoni Version: 2.4.16 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (82.63.140.131) Scenario: OpenLDAP 2.4.16 with patches for back-bdb (up to may 1st) and syncrepl. Master-slave configuration using syncrepl refreshAndPersist. Two hdb databases per instance. Replica hit assert in slap_modrdn2mods and dumped core. Since no MODRDN operation is ever being performed on entries I wonder why. Anyway, here the bt full: #0 0x004017a2 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2 No symbol table info available. #1 0x004427a5 in raise () from /lib/tls/libc.so.6 No symbol table info

(ITS#6095) slapd stops accepting connections

Full_Name: Quanah Gibson-Mount Version: 2.4.16 + current back-hdb OS: Linux 2.6 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (75.111.29.239) After applying the latest fixes to servers/slapd/back-bdb for the cache problems and dn2id problems, it now locks up and stops accepting connections. It looks like it may be all waiting on locks in bdb?

Re: (ITS#6089) connection_destroy() c->c_writers == 0 assertion failure
by jwm＠horde.net 05 May '09

05 May '09

Poked around a bit in the core: (gdb) print c->c_writers $1 = -1 (gdb) print c->c_pending_ops->stqh_last[0] $5 = (struct Operation *) 0x0 (gdb) print c->c_n_ops_pending $6 = 0 So there are no pending ops on this connection, but c_writers == -1 indicates that one blocked writer remains to notice that the connection has been closed. I looked at send_ldap_ber() and can't immediately find fault with its manipulation of c_writers. connection_closing() wakes up all blocked writers, so by the time connection_close() calls connection_destroy() and this assertion is checked, c_writers should be 0. Furthermore, c->c_conn_state is SLAP_C_CLOSING (0x4), which can only happen in connection_closing(). This is about as far as I can get; any other ideas? john (gdb) print *c $2 = {c_struct_state = 2, c_conn_state = 4, c_conn_idx = 1878, c_sd = 1878, c_close_reason = 0x0, c_mutex = {__data = {__lock = 1, __count = 0, __owner = 9540, __kind = 0, __nusers = 1, {__spins = 0, __list = { __next = 0x0}}}, __size = "\001\000\000\000\000\000\000\000D%\000\000\000\000\000\000\001\000\000\000\000\000\000", __align = 1}, c_sb = 0x175c7240, c_starttime = 1240942246, c_activitytime = 1240942264, c_connid = 73097614, c_peer_domain = {bv_len = 7, bv_val = 0x137e02c8 "unknown"}, c_peer_name = { bv_len = 23, bv_val = 0x191c0be0 "IP=172.16.182.103:50023"}, c_listener = 0x9bb7370, c_sasl_bind_mech = {bv_len = 0, bv_val = 0x0}, c_sasl_dn = {bv_len = 0, bv_val = 0x0}, c_sasl_authz_dn = {bv_len = 0, bv_val = 0x0}, c_authz_backend = 0x9bba500, c_authz_cookie = 0x0, c_authz = {sai_method = 128, sai_mech = {bv_len = 0, bv_val = 0x0}, sai_dn = {bv_len = 27, bv_val = 0x1876bd20 "cn=nsspluspasswd,o=example2"}, sai_ndn = {bv_len = 27, bv_val = 0x189f5780 "cn=nsspluspasswd,o=example2"}, sai_ssf = 128, sai_transport_ssf = 0, sai_tls_ssf = 128, sai_sasl_ssf = 0}, c_protocol = 3, c_ops = {stqh_first = 0x0, stqh_last = 0x9d7df18}, c_pending_ops = {stqh_first = 0x0, stqh_last = 0x9d7df20}, c_write1_mutex = { __data = {__lock = 0, __count = 0, __owner = 0, __kind = 0, __nusers = 0, { __spins = 0, __list = {__next = 0x0}}}, __size = '\0' <repeats 23 times>, __align = 0}, c_write1_cv = {__data = { __lock = 0, __futex = 2, __total_seq = 1, __wakeup_seq = 1, __woken_seq = 1, __mutex = 0x9d7df28, __nwaiters = 0, __broadcast_seq = 1}, __size = "\000\000\000\000\002\000\000\000\001\000\000\000\000\000\000\000\001\000\000\000\000\000\000\000\001\000\000\000\000\000\000\000(##\t\000\000\000\000\001\000\000\000\000\000\000", __align = 8589934592}, c_write2_mutex = { __data = {__lock = 0, __count = 0, __owner = 0, __kind = 0, __nusers = 0, { __spins = 0, __list = {__next = 0x0}}}, __size = '\0' <repeats 23 times>, __align = 0}, c_write2_cv = {__data = { __lock = 0, __futex = 0, __total_seq = 0, __wakeup_seq = 0, __woken_seq = 0, __mutex = 0x0, __nwaiters = 0, __broadcast_seq = 0}, __size = '\0' <repeats 47 times>, __align = 0}, c_currentber = 0x0, c_writers = -1, c_sasl_bind_in_progress = 0 '\0', c_writewaiter = 0 '\0', c_is_tls = 1 '\001', c_needs_tls_accept = 0 '\0', c_sasl_layers = 0 '\0', c_sasl_done = 0 '\0', c_sasl_authctx = 0x13497200, c_sasl_sockctx = 0x0, c_sasl_extra = 0x14d956c0, c_sasl_bindop = 0x0, c_pagedresults_state = { ps_be = 0x0, ps_size = 0, ps_count = 0, ps_cookie = 0, ps_cookieval = { bv_len = 0, bv_val = 0x0}}, c_n_ops_received = 6, c_n_ops_executing = 0, c_n_ops_pending = 0, c_n_ops_completed = 6, c_n_get = 4, c_n_read = 4, c_n_write = 0, c_extensions = 0x0, c_clientfunc = 0, c_clientarg = 0x0, c_send_ldap_result = 0x808aea0 <slap_send_ldap_result>, c_send_search_entry = 0x80885e0 <slap_send_search_entry>, c_send_search_reference = 0x8087da0 <slap_send_search_reference>, c_send_ldap_extended = 0x808a910 <slap_send_ldap_extended>, c_send_ldap_intermediate = 0x808a760 <slap_send_ldap_intermediate>} -- John Morrissey _o /\ ---- __o jwm(a)horde.net _-< \_ / \ ---- < \, www.horde.net/ __(_)/_(_)________/ \_______(_) /_(_)__

In fact, the uniqueness check for add seems to assume that the current entry will implicitly match the uniqueness filter, which may not be the case if an additional filter is provided within the URI. > Fixing this for unique_add seams easy enough (see preliminary attached > patch) - fixing it for modrdn/modify seems to be another difficulty > level as in order to properly apply the filter I think the full > modifications have to be applied... > > If wanted I can produce a patch for this as well, but I would like to > know if that is appreciated and if my plan for fixing looks sensible: > - Pull the "modification simulation" code out of constraint.c (line > 959:1040 and some more in 2.4.16) into constraints.c > - Add a overlay-int.h > - Make constraint.c and unique.c use that > > As I dont really know the openldap codebase my analysis could be > completely wrong - I would appreciate some feedback. Yes, the code provided in the constraint overlay is exactly intended to simulate the modification in order to be able to assess the consistency of the resulting entry with the constraint. What you suggest sounds reasonable; a patch would definitely be welcome. The code extracted from constraint.c should probably be placed in slapd, and always built since other portions of slapd might need it in the future. Please note that overlays can be selectively built, or even built as modules, so creating cross-dependences is not a good idea IMHO. p.
