ASF subversion and git services commented on PROTON-611: -------------------------------------------------------- Commit 1630778 from [~gsim] in branch 'proton/branches/examples' [ https://svn.apache.org/r1630778 ] PROTON-611: Don't allocate frame_max bytes immediately, grow by factors of 2 until you get to the max - else a large frame size can blow away 4Gb of memory! > [proton-c] transport buffer increased to peer's max frame size if initial > output_size is not enough > --------------------------------------------------------------------------------------------------- > > Key: PROTON-611 > URL: https://issues.apache.org/jira/browse/PROTON-611 > Project: Qpid Proton > Issue Type: Bug > Components: proton-c > Affects Versions: 0.7 > Reporter: Dominic Evans > Assignee: Andrew Stitcher > Fix For: 0.8 > > Attachments: 20_fix_bad_malloc_in_transport_produce.patch > > > transport_produce attempts to allocate a negatively sized buffer > As soon as remote_max_frame is set, the code in transport_produce attempts to > increase its buffer immediately up to that size when its initial size isn't > enough. This causes a huge malloc to occur if the remote max frame size is > large and also potentially overflows MAX_INT -- This message was sent by Atlassian JIRA (v6.3.4#6332)
