Last Modified: Sep 13, 2023

Affected Product(s):
BIG-IP Install/Upgrade(all modules)

Known Affected Versions:
12.1.2, 12.1.3,,,,,,,, 12.1.4,, 12.1.5,,,, 12.1.6

Fixed In:

Opened: Jul 11, 2017

Severity: 4-Minor


When IPsec log-level is debug, sometimes logged payloads have line breaks in the middle, and most lines are missing a single character at line end, such as a closing parenthesis or quote.


Distracting imperfections in debug log output.


Log level set to debug, then passing v2 IPsec traffic.


No workaround at this time.

Fix Information

A larger buffer was used to reduce line breaks. Missing characters at line's end were due to incorrect swapping of one function for another that reserved a byte for a terminating null, when the size to copy was the line length; so the size to copy had to be increased to include an end null so it could be removed without shortening the line.
