2.6.27-stable review patch. If anyone has any objections, please let us know. ------------------ From: Guillaume Knispel commit af4d3643864ee5fcba0c97d77a424fa0b0346f8e upstream. There is an error in rh_alloc_fixed() of the Remote Heap code: If there is at least one free block blk won't be NULL at the end of the search loop, so -ENOMEM won't be returned and the else branch of "if (bs == s || be == e)" will be taken, corrupting the management structures.
