Description

Linux: grow a unique random mapping in ASLR We loosen ASLR by only growing one random mapping. The previous version had security benefits but had a negative performance impact. This change aims to be performance neutral in respect to the pre-ASLR era. At a later date, we may try to strike a good balance between performance and security. This is a re-land of https://chromiumcodereview.appspot.com/12090112/ BUG=170133, 173371 NOTRY=true TBR=jar Committed: https://src.chromium.org/viewvc/chrome?view=rev&revision=180556
