by dw＠botanicus.net 25 Mar '13

25 Mar '13

Full_Name: David Wilson Version: master OS: OS X URL: http://pastie.org/7114932 Submission from: (NULL) (109.149.47.172) Please find attached a crash repro affecting current MDB master, where seeking to the last database key followed by double mdb_cursor_del() results in a crash. The program supplied crashed with NULL+0x10 pointer dereference, however another crash triggered by the same set of steps results in a separate stack trace: Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: KERN_PROTECTION_FAILURE at address: 0x0000000100fffff0 0x00000001005e566c in memmove$VARIANT$sse3x () (gdb) bt #0 0x00000001005e566c in memmove$VARIANT$sse3x () #1 0x0000000101dd81d0 in mdb_node_del (mp=0x10111ce20, ksize=10, indx=52758) at mdb.c:5582 #2 0x0000000101dda308 in mdb_cursor_del (mc=0x10202ed80, flags=0) at mdb.c:6422 #3 0x0000000101dd51a4 in _cffi_f_mdb_cursor_del (self=0x10111ce20, args=0x10111ce20) at _cffi__xfbbb05bexaac0bea3.c:648 #4 0x000000010008bd77 in PyEval_EvalFrameEx ()

(ITS#7551) [lmdb] bugfix for mdb_cursor_put with MDB_MULTIPLE
by claude.brisson＠gmail.com 22 Mar '13

22 Mar '13

Full_Name: Claude Brisson Version: HEAD OS: linux URL: ftp://ftp.openldap.org/incoming/0001-bugfix-for-mdb_cursor_put-with-MDB_MUL… Submission from: (NULL) (86.76.238.178) (once again with the attachment...) This patch fixes the following problem: In mdb_cursor_put, section 'put_sub', if the variable dkey.mv_size is non-zero, then it means dkey contains some original data which has to be put back in the child db, typically when the child db has just been created. But when using MDB_MULTIPLE, if this variable has not been resetted to zero, we may come back to this section and wrongly think that there is some original data to be taken care of.
