(ITS#7862) slapd crash on modifications after host hard reset (in mdb)

Full_Name: Vadim Prozorov Version: 2.4.38 OS: RHEL 6.3 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (91.210.4.1) Hello, I'm using slapd (2.4.38 release) built from sources on RHEL 6.3 64bit.

(ITS#7861) Wrong entry count with MDB_DUPSORT databases
by h.b.furuseth＠usit.uio.no 27 May '14

27 May '14

Full_Name: Hallvard B Furuseth Version: mdb.master, 4b9aed26a5b1c0027b10d211c6e7270dbb1ade1c OS: Linux x86_64 URL: Submission from: (NULL) (2001:700:100:556::233) Submitted by: hallvard mdb_cursor_put() does not always know if it'll be inserting a new item or not, e.g. when inserting in a sub-database. This was always wrong, but recent commits changed how it was wrong. Fix: Split 'insert' in 'insert_key' + 'insert_data'. Compute insert_data from mx_db.md_entries before and after the insert. In my UiO repo, branch mdb/todo-3: 02dd3865d5 [Rewritten] ITS#xxxx Fix MDB_db.md_entries. c6c78f71d3 [New] Tweak varname 'insert'. (Cosmetic patch which does not apply cleanly, I guess I should make an mdb/todo-4 branch where it is applied earlier.) Affects ITS#7834. mdb_cursor_del(, MDB_NODUPDATA) only subtracts 1 from md_entries when deleting a sub-page, instead of no of DUP entries. Fix: fa8e827026 [New,Squash] Fix md_entries in mdb_cursor_del:MDB_NODUPDATA.

This appears to be the result of an intentional backward-compatiblility kludge. While the spec may have defaulted to 76 chars, the UMich code has always output 78 columns by default, so there's an offset built in to the LDIF output functions. This offset wasn't taken into account when the variable output width support was written. Probably we should just remove the kludge and define our default output width to 78 instead of pretending it's still 76. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

(ITS#7859) ldif processing issue with long lines
by mwarren＠symas.com 26 May '14

26 May '14

Full_Name: Mark Warren Version: 2.4.35 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (72.35.133.119) A customer of ours has identified an issue with slapadd and lines right at the maximum length(4096 characters). Howard has taken a look and reports the following: I took a quick look at the slapadd issue; libldap/ldif.c is using an input buffer of size [LDIF_MAXLINE] which is 4096 characters. It uses fgets() to read the input. The problem is that fgets() always stores a terminating NUL character, which means the buffer can only accept an input of up to 4095 characters. The input line in question is "only" 4095 characters long, but in reality it also has a terminating newline, making it 4096. The end result, fgets() reads the data but leaves the newline in the input buffer since there's no room for it in the user buffer. Then the next call to fgets() returns just this newline all by itself, which signals to ldif_read_record that it's come to the end of the entry, and so it treats the next input line as a new entry even though it's supposed to be a continuation of the previous line. The simple fix here is to bump up the input buffer size by 1, to accommodate the terminating newline. Actually the buffer needs to be upped by 2, to allow for CR/LF line terminators. -- End Howard Quote -- Also, another issue has been reported where the length of LDIF lines is greater by two than a specified 'ldif-wrap' definition when using slapcat. Regards, Mark Warren
