[NFS-Ganesha-Devel] NFS Ganesha in mdcache_avl_qp_lookup_s()

Frank, Long time. We are seeing a crash shown below. After seeing the fix in this commit - https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/516675, I am posting a possible fix. (gdb) where #0 0x00000000004f2a34 in avl_dirent_hk_cmpf (lhs=0x2, rhs=0x7f82ebf8b5c8) at ../../../../FSAL/Stackable_FSALs/FSAL_MDCACHE/mdcache_avl.h:67 #1 0x00000000004f3d48 in avltree_do_lookup (tree=0x7f82d31bbd90, cmp_fn=0x4f2a30 <avl_dirent_hk_cmpf>, is_left=<synthetic pointer>, unbalanced=<synthetic pointer>, pparent=<synthetic pointer>, key=0x7f82ebf8b5c8) at ../../../../include/avltree.h:223 #2 avltree_inline_lookup (cmp_fn=0x4f2a30 <avl_dirent_hk_cmpf>, tree=0x7f82d31bbd90, key=0x7f82ebf8b5c8) at ../../../../include/avltree.h:244 #3 avltree_lookup (tree=0x7f82d31bbd90, key=0x7f82ebf8b5c8) at ../../../../include/avltree.h:252 #4 mdcache_avl_qp_lookup_s (entry=entry@entry=0x7f82d31bb800, name=name@entry=0x7f82c606f440 "meta.tmp", maxj=maxj@entry=1) at ../../../../FSAL/Stackable_FSALs/FSAL_MDCACHE/mdcache_avl.c:779 Possible fix – diff mdcache_avl.c mdcache_avl.c.new 760a761,762 I also suggest reviewing all callers of this avltree_lookup() for potential similar problems. Comments? Regards.
