The relevant part of the doc is "It must be set TRUE when using the accesslog overlay for delta-based syncrepl support." Otherwise it has no effect, so there is no reason to change it in the default case. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

Actually, since it is not a valid configuration scenario to have a 2.4 provider and a 2.3 consumer, it seems that the configuration option should be deprecated entirely, and the internal code simply default to TRUE. --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

(ITS#8584) reloadhint for syncprov overlay should default to TRUE

Full_Name: Quanah Gibson-Mount Version: 2.4.44 OS: N/A URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (47.208.148.26) The "reloadhint" option for the syncprov overlay currently defaults to FALSE. However, the documentation clearly notes that you want to set it to true for any release > 2.3.11. Given that 2.3 has been obsolete for years and it has been over 11 years since the release of 2.3.11, we should really fix the default value, and note that it should be changed if and only if there is a consumer running 2.3.11 or prior.

To note, this was a configuration error where accesslog overlay was being configured to write ops back onto itself. We should probably check for this and reject it (vs allowing it to lock up slapd). --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

(ITS#8582) LMDB lockfile/mutex arch dependency
by hyc＠openldap.org 06 Feb '17

06 Feb '17

Full_Name: Howard Chu Version: HEAD OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (195.235.15.200) Submitted by: hyc I ran into some corruption problems when running a 64bit LMDB process concurrent with a 32bit one using MDB_VL32. While LMDB's own structures are all 64bit clean in a VL32 build, unfortunately pthread_mutex_t structures are not. In particular, in glibc a pthread_mutex_t can be one of 3 different sizes - 24 bytes for 32bit runtime on 32bit processor, 32 bytes for 32bit runtime on x86-64, and 40 bytes for 64bit runtime on x86-64. As such, we cannot safely share an LMDB environment between 32 and 64bit Linux processes, even when using MDB_VL32. This problem doesn't affect Windows, platforms using SysV semaphores, or platforms using POSIX named semaphores. I don't currently know whether this is a problem on other platforms that support POSIX process-shared mutexes. Hallvard has suggested that we add some additional LOCK_FORMAT bits to protect against incompatible accesses. This would primarily be useful for the mdb_stat command, which can still safely retrieve some useful information from an environment without acquiring any mutexes. E.g., an MDB_VL32 build of mdb_stat could retrieve most envinfo, statinfo, and readerinfo from a running 64bit environment. It could not scan the freelist, scan all the names of named DBs, or clean the reader list, since these operations all require taking the reader mutex.

(ITS#8581) slapd-meta backend SSL negociation timeout

04 Feb '17

Full_Name: Louis Chanouha Version: 2.4.40 OS: Debian 8 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (90.76.56.40) Hello, I experience some problems with slapd-meta with ldaps backend. gnuTLS (or openssl) negociation timeout seems not to be handled, and i can't find any reference to modify this timeout on docs. My server becames unresponsive (too many connexion slots) when a ssl-secured backend server time out after TCP connexion establishment. To reproduce the error, i have an meta directory configured like this: database meta suffix "dc=localauth" rootdn "%n=Manager,dc=localauth" rootpw XXX uri "ldaps://localhost:666/ou=UT,dc=localauth" lastmod off suffixmassage "ou=UT,dc=localauth" "ou=people,dc=example,dc=fr" timeout 1 conn-ttl 1 network-timeout 1 And i launch a netcat to listen to the 666 port: nc -l -p 666 Then, this command never time out: ldapwhoami -H ldap://YYYY:9009 -D uid=me,ou=UT,dc=localauth -W Error does not happen when no ssl used ("timeout 1" option works well) OS: Debian 8 Jessie x64 slapd: 2.4.40+dfsg-1+deb8u2 gnutls: 3.3.8-6+deb8u4 Sorry for my english, and thanks for the help, Regards, Louis Chanouha University of Toulouse

(ITS#8579) LMDB: me_fd should be O_CLOEXEC on POSIX systems
by lmb＠cloudflare.com 03 Feb '17

03 Feb '17

Full_Name: Lorenz Bauer Version: OS: Linux URL: Submission from: (NULL) (2a06:98c0:1000:8200:18fd:e772:495e:6163) This is in some ways a follow up to ITS#8505. In the issue I argued that LMDB did not deal well with fork/exec. Hallvard committed a fix in 04acac634a7b276332e2. I think the fix still has one major weakness: me_fd does not have O_CLOEXEC set. Now, Hallvard omitted this change on purpose. mdb_env_get_fd() exposes me_fd to the user, so there could conceivably be client code out there which expects the fd to persist across exec(). (Please correct my if I misunderstood your argument.) I believe that the correct action is to set O_CLOEXEC on me_fd by default, and break such client code. 1. Using mdb_env_get_fd this way is Undefined Behaviour (according to the doc) Before ITS#8505, the documentation made it sound like ANY use after fork() / exec() is disallowed. At the same time, mdb_env_get_fd made no mention / promises wrt exec() behaviour. Adopting O_CLOEXEC in my opinion does not violate the API set out so far. We can, in the opposite, clarify what is acceptable use (as Hallvard already has done). 2. mdb_env_get_fd has inconsistent semantics across OSs When creating file handles on Windows we pass NULL as the lpSecurityAttributes argument to CreateFileW: If this parameter is NULL, the handle returned by CreateFile cannot be inherited by any child processes the application may create [...] me_fd already has O_CLOEXEC on Windows. 3. Manually closing me_fd after fork() is not possible in all environments Hallvard suggests calling fork(), close(mdb_env_get_fd()) and then exec() for users which do not want to leak me_fd to child processes. We use LMDB from the Go platform, which does not expose fork and exec separately (due to the well-known pitfalls they have). We can't use Hallvard's suggestion therefore. 4. me_fd can still be passed around by dup()ing the handle If there are legitimate uses of passing the handle around, users can explicitly dup the handle and then pass it on to child processes. I hope my arguments are convincing enough to make the change before the next release. The benefits are * Consistent semantics between OS * (In my view) saner defaults * and a solution which works well across environments. The downside is that we might break unknown client code. I can'c come up with a use case of passing me_fd to children, so I suspect the risk is low. The patch itself is trivial, and I'm happy to contribute it if desired. Lorenz
