(ITS#8760) LMDB: seg fault on opening a new database
by github＠nicwatson.org 22 Oct '17

22 Oct '17

Full_Name: Nic Watson Version: LMDB 0.9.21 OS: Ubuntu 16.04.3 LTS URL: https://gist.github.com/jnwatson/86b43b0515fe552a087d741d4ab43922 Submission from: (NULL) (108.56.136.246) See the URL for the minimal C program to reproduce the crash and the gdb backtrace. LMDB will seg fault in mdb_dbi_open when creating a new database if the environment was opened read-only. This was found trying to update py-lmdb from 0.9.19 to 0.9.21. Two unit tests crashed that didn't crash before, both on the same line in mdb.c. The program in the URL is derived from one of the tests. The change was introduced in commit e8e82933. In mdb.c, line 9772 (https://github.com/LMDB/lmdb/blob/LMDB_0.9.21/libraries/liblmdb/mdb.c#L9772) the mdb_cursor_put was wrapped in the macro WITH_CURSOR_TRACKING. In that macro, the variable tp is assigned the address of an entry of the passed-in cursor's transaction's mt_cursors array. However, mt_cursors isn't initialized in this case.

(ITS#8759) mixed overlay nops & memberof cause segfault
by zhixu.liu＠gmail.com 20 Oct '17

20 Oct '17

Full_Name: Z. Liu Version: 2.4.44 OS: Gentoo URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (221.218.169.84) if we enable overlay nops & memberof together, then doing a member MODDN operation, slapd will segfault and exit immediately. Example operation: dn: uid=test,ou=People,dc=example,dc=dc=com changetype: moddn newrdn: uid=chenln deleteoldrdn: 1 newsuperior: ou=Leave,dc=example,dc=com The reason is: in servers/slapd/overlays/memberof.c, function memberof_value_modify define mod/values/nvalues in the stack, which will be passed to other overlays, nops will try to free them if no attribute is changed.

(ITS#8757) RFE: let slapd MMR instances vote primary master
by michael＠stroeder.com 19 Oct '17

19 Oct '17

Full_Name: Michael Str.der Version: OS: URL: Submission from: (NULL) (217.145.44.194) In some situations having a "primary" master would be very useful (e.g. where to assign numeric IDs). The providers connected with MMR could try to vote a primary master with the raft algorithm: https://raft.github.io/ Ideally it should be visible in cn=monitor whether a provider replica is the current primary master. Let's discuss this at LDAPcon dinner this evening... ;-)

Attached is a re-based patch set since there were changes in git master in last month or so that affected the same area. There are two patches: one for git master, one for 2.4 branch.

(ITS#8756) assertion in mdb_page_dirty() due to loose pages
by h.b.furuseth＠usit.uio.no 18 Oct '17

18 Oct '17

Full_Name: Hallvard B Furuseth Version: mdb.master, bb8502f08800a44a6b91a94d6478aa7101c4cc77 OS: URL: Submission from: (NULL) (193.71.61.52) Submitted by: hallvard Described here with a fix, and with discussion in the thread: http://www.openldap.org/lists/openldap-devel/201710/msg00019.html "Inside freelist_save() the mt_loose_pages could be merged into the mt_free_pgs. http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=blob;f=libraries/… But at this point all loose_pages also still present in the mt_u.dirty_list. On the next loop inside freelist_save() a one more page could be requested, and page_alloc() could return a page which is already in the mt_u.dirty_list. In this case mdb_mid2l_insert() will return -1." We could catch and handle the error when WRITEMAP is not in use. Another fix is for freelist_save() to quit messing with loose pages and just reserve room for them, like it does for me_pghead. In LMDB 1.0, we'll have more options.
