[jira] [Commented] (MYNEWT-787) serial boot loader - newtmgr buffer
overruns
[ https://issues.apache.org/jira/browse/MYNEWT-787?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16054949#comment-16054949 ]
ASF subversion and git services commented on MYNEWT-787:
--------------------------------------------------------
Commit 09408a3fa9d24d5f7bb2436867e247b48e3b58ae in incubator-mynewt-core's branch refs/heads/master from [~ccollins476]

MYNEWT-787 serial boot loader - nmp buf overruns
The serial boot loader fails to process some newtmgr commands:
1. The image list response is too large for the outgoing buffer.
2. The "new" newtmgr sends large image chunks in its image upload
requests. These chunks are too large for the serial boot loader's
input buffer.
The fixes are as follows:
1. Increase the outgoing buffer size from 48 to 80.
2. Increase the incoming buffer size from 128 to 512.
3. Return an error rather than overrun the output buffer.
