Oracle Linux Bug Fix Advisory ELBA-2018-4107


The following updated rpms for Oracle Linux 6 have been uploaded to the 
Unbreakable Linux Network:




Description of changes:

- 'unacknowledged_bad_blocks' is a long name for sysfs property and it
   makes sysfs path over 50 characters long. Increase buffer to the double
   length of the longest path available in sysfs at the moment.

- Linux allows for 32 character device names. When using the maximum
   size device name and also storing "/dev/", devname needs to be 37
   character long to store the complete device name.
   i.e. "/dev/md_abcdefghijklmnopqrstuvwxyz12\0"
- Newer kernels don't allow for specifying an array larger than 511.
   This makes it so find_free_devnm wraps to 511 instead of 2^20 - 1.
- mdadm will fail in operating on a device with a minor number
   bigger than (2^19)-1 due to it changing from dev_t to a signed int
   and back.
