If a region has a a DMS_GROUP tag in aux_data where the first region_id in the bitmap is not the same as the containing region, dmstats will segfault: # '2' is never a valid group bitset list for region_id == 0 # dmsetup message vg_hex/root 0 "@stats_set_aux 0 DMS_GROUP=img:2#" # dmsetup message vg_hex/root 0 "@stats_list" 0: 45383680+16384 16384 dmstats DMS_GROUP=img:2# 1: 46071808+32768 32768 dmstats - 2: 47382528+16384 16384 dmstats - # dmstats list Segmentation fault (core dumped) The crash will occur in some arbitrary dm_stats_get_* property method - this happens while processing the 1st region_id in the bitset, because the region is marked as grouped, but there is no group bitmap present at dms->groups[2]->regions. Fix this by detecting a mismatch between the expected region_id and dm_bit_get_first() for the parsed bitset during _parse_aux_data_group(). |
