trociny 1fecf4ec8c In snmp_hostres, device_map table is used for consistent device table ... indexing. When a device has gone it is not removed from device_map table but just its entry_p field is set to NULL. So when traversing device_map in disk_OS_get_ATA_disks() and disk_OS_get_MD_disks() check for entry_p being NULL, otherwise the bsnmpd crash is possible when a removed map entry is dereferenced. Before the fix, for disk_OS_get_ATA_disks() the crash could be easily reproduced running: atacontrol detach ata1 The crash was not observed in disk_OS_get_MD_disks() because currently snmp_hostres does no see md(4) disks: to get the device list it uses devinfo(3), which does not return md devices.
