| |
This is the official announcement of the release of LTTng-modules 2.9.0. Release name: Joannès.
The LTTng modules provide Linux kernel tracing capability to the LTTng 2.9 tracer toolset.
New and Noteworthy for LTTng-modules 2.9:
* Various performance improvements. Tested on x86-64 and ARM32. * Add bitfield, enumeration, variant, structure, compound array/sequence types. * Add custom field support. * IPv4, IPv6, and TCP header data is now traced with the net_. tracepoints. * Implement select, pselect6, poll, ppoll, epoll_wait, epoll_pwait, epoll_ctl, detailed system call tracing. * The accept4() system call payload detail is now traced on x86-64. * New "i2c" instrumentation. We introduce the module parameter "extract_sensitive_payload" for this probe. It is disabled by default. When enabled, it allows tracing i2c payload information which may contain sensitive data (e.g. keystrokes). * When lttng-modules gets built into the kernel image, select TRACEPOINTS rather than depending on it.

The release name "Joannès" is named after a Berliner Weisse style beer from the Trèfle Noir microbrewery in Rouyn-Noranda. It is a tangy beer with a distinct pink dress and intense fruit flavor, thanks to the presence of fresh blackcurrant grown in Témiscamingue.
Changelog:
