[jira] [Created] (CLOUDSTACK-5949) Removed unused field
vnc_password from user_vm_view
Koushik Das created CLOUDSTACK-5949:
---------------------------------------
Summary: Removed unused field vnc_password from user_vm_view
Key: CLOUDSTACK-5949
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-5949
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Management Server
Affects Versions: 4.3.0
Reporter: Koushik Das
Priority: Critical
Fix For: 4.3.0
vnc_password is an encrypted field. During any list VM query this field is decrypted and then returned. In a scaled up environment if many simultaneous list VM queries are run then this may result in blocked threads as shown below. A single instance of StandardPBEByteEncryptor is used for encryption/decryption. Due to this all decrypt calls during list VM queries get blocked as the decrypt method is thread safe (see http://www.jasypt.org/api/jasypt/1.8/org/jasypt/encryption/pbe/StandardPBEStringEncryptor.html)
