Found this when examining the logs where the search filter has 500 users in it, in the form of: "(&(objectClass=userobject)(|(uid=abc)(uid=xyz)....)" In the slapd log, the filter gets truncated and the next log line is appended, so we end up with ...(uid=joe.hSep 27 18:21:09 hostname slapd[6373]: conn=1234 op=123 SEARCH RESULT tag=101 err=0 qtime=0.xxxx etime=0.xxx nentries=500 text= -- You are receiving this mail because: You are on the CC list for the issue.

https://bugs.openldap.org/show_bug.cgi?id=10124 Issue ID: 10124 Summary: olcTLSDHParamFile causes slapd general protection fault error:0 in libcrypto.so.3.0.7 Product: OpenLDAP Version: 2.5.16 Hardware: All OS: Linux Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: r.g.van.der.kleij(a)umail.leidenuniv.nl Target Milestone: --- I am not sure this is even an openldap bug, but just in case it is I report it here. I build openldap 2.5 from source on Rocky linux 9.2. The previous build version 2.5.14 would run fine, but 2.5.16 would crash at startup with error: kernel: traps: slapd[3909] general protection fault ip:7fea2f19f2d2 sp:7fff76b17c00 error:0 in libcrypto.so.3.0.7[7fea2f0ad000+25b000] Since even in full debug nothing was logged apart from this error I started eliminating configuration items, ending up with only the config below. A fresh slapd 2.5.14 would start with only this ldif slapadded, 2.5.16 would not on the same server. Leaving out olcTLSDHParamFile would cause everything to work again. I tried regenerating a fresh 2048 bit dhparam file instead of the 4096 I was using, but no difference. openssl dhparam -out ./dhparam.pem 2048 dn: cn=config objectClass: olcGlobal cn: config olcArgsFile: /var/run/scs-slapd/slapd.args olcDisallows: bind_anon olcLogLevel: stats sync olcPasswordCryptSaltFormat: $6$%.16s olcPasswordHash: {CRYPT} olcPidFile: /var/run/scs-slapd/slapd.pid olcRequires: authc olcTLSCACertificateFile: "/etc/scs/openldap/certs/ca_chain.pem" olcTLSCertificateFile: /etc/scs/openldap/certs/cert.pem olcTLSCertificateKeyFile: /etc/scs/openldap/certs/key.pem olcTLSCipherSuite: ECDHE-RSA-AES256-SHA384:AES256-SHA256:!RC4:HIGH:!MD5:!aNULL :!EDH:!EXP:!SSLV2:!eNULL olcTLSCRLCheck: none olcTLSVerifyClient: allow olcTLSDHParamFile: /etc/ssl/dhparam.pem olcTLSProtocolMin: 3.3 olcToolThreads: 2 Both openssl-devel and gnutls-devel were available on the build system, but as far as I can see openssl would be preferred when available and was indeed used. (I tried both --with-tls=auto and --with-tls=openssl ) Make test would finish without issues My configure options: ./configure --prefix=$SCS_TARGET --sysconfdir=$SCS_TARGET_ETC \ --enable-debug \ --enable-slapd \ --with-systemd \ --enable-modules \ --with-tls=auto \ --with-cyrus-sasl \ --with-argon2 \ --enable-crypt \ --enable-spasswd \ --enable-rlookups \ --enable-overlays=mod \ --enable-syncprov=yes \ --enable-accesslog=mod \ --enable-backends=mod \ --enable-mdb=yes \ --enable-ndb=no \ --enable-sql=no \ --enable-wt=no \ --disable-shell The results in the configure log: TLS_LIBS='-lssl -lcrypto' WITH_TLS='yes' WITH_TLS_TYPE='openssl' -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10135] New: dynlist (and maybe others) doesn't use the right overinst context in callbacks

https://bugs.openldap.org/show_bug.cgi?id=10135 Issue ID: 10135 Summary: dynlist (and maybe others) doesn't use the right overinst context in callbacks Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: ondra(a)mistotebe.net Target Milestone: --- Running the test suite with `-fsanitize=address` picks up a bug in https://git.openldap.org/openldap/openldap/-/blob/860b61f41dfeeb19cc0eb011f… Here, op->o_bd->bd_info isn't actually dynlist but mdb's own static bi, so overlay_entry_get_ov then reaches into the void when reading on->on_info. It's very likely that other places/overlays share the same bug as it is subtle and doesn't get picked up immediately (slap_overinst embeds a BackendInfo and oi_orig is not often set). -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10101] New: Fix double file close when first TLS connection fails

https://bugs.openldap.org/show_bug.cgi?id=10101 Issue ID: 10101 Summary: Fix double file close when first TLS connection fails Product: OpenLDAP Version: 2.6.2 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: libraries Assignee: bugs(a)openldap.org Reporter: florin.crisan(a)axigen.com Target Milestone: --- Created attachment 981 --> https://bugs.openldap.org/attachment.cgi?id=981&action=edit Proof of concept 1. ldap_initialize a connection with multiple URLs, the first one being LDAPS. (For example: "ldaps://server,ldap://server"). The LDAPS connection needs to successfully open the TCP connection, but fail during TLS negotiation. 2. When TLS negotiation fails, ldap_int_open_connection calls ber_int_sb_close (which closes the connections attached to the sockbuf) but fails to call ber_int_sb_destroy, so the TCP layers are still attached to the sockbuf structure. 3. When the second connection is opened, a new TCP layer is added to the sockbuf structure, but the existing one is still there. Both now point to the updated sockbuf structure, with the new file descriptor. 4. When the connection is closed, the layers attached to the sockbuf close the new file descriptor twice.
