Problems with Data Types, High Severity (1)

	Change	Effect
1	Field cs_dispatch has been removed from the middle position of this structural type.	1) Previous accesses of applications to the removed field will be incorrect. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

[+] struct crm_cluster_s (1)

to the top

Problems with Data Types, Medium Severity (1)

	Change	Effect
1	Field flags has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

cluster.h
[+] struct crm_peer_node_s (1)

to the top

Problems with Symbols, Medium Severity (3)

	Change	Effect
1	Type of return value became const (has been changed from char* to char const*).	The return value will be treated as non-const by old client applications. This may result in crash or incorrect behavior of applications.

	Change	Effect
1	Base type of 3rd parameter uname has been changed from char (1 byte) to struct crm_peer_node_s (96 bytes).	This parameter may be incorrectly initialized by applications.

	Change	Effect
1	This global data became non-const.	This data will be copied to applications at compile time. Any attempts to change this global data by library functions may result in crash of applications.

2	Field cpg_handle has been added to this type.	1) This field will not be initialized by old clients. 2) Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
3	Field group has been added to this type.	1) This field will not be initialized by old clients. 2) Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
4	Size of this type has been changed from 40 bytes to 192 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Size of this type has been changed from 88 bytes to 96 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Field maintenance has been added to this type.	1) This field will not be initialized by old clients. 2) Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
2	Size of this type has been changed from 112 bytes to 120 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Field localhost has been added to this type.	1) This field will not be initialized by old clients. 2) Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
2	Size of this type has been changed from 208 bytes to 216 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Type of return value has been changed from char* to char const*.	Replacement of return type may indicate a change in its semantic meaning.

	Change	Effect
1	1st parameter node has been renamed to xml.	Renaming of a parameter may indicate a change in its semantic meaning.
2	3rd parameter uname has been renamed to node.	Renaming of a parameter may indicate a change in its semantic meaning.

	Change	Effect
