[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



This is a release announcement for the 2.11.8 and 2.12.5 releases of the
LTTng kernel tracer.

New and noteworthy in these releases:

* Support for Linux kernel 5.11,
* Deal with stable kernel version overflow (sublevel >= 256),
* Prepare for Ubuntu, SLES, RHEL, and RT release version overflows (which should come sooner
  or later),
* Writeback instrumentation: fix out-of-bound read of block device name beyond terminating
  '\0' character,
* Writeback instrumentation: fix a crash in wb_workfn when a device disappears when memcg
  is in use,
* aarch64: blacklist gcc compiler prior to version 5.1, because they perform unsafe access
  to deallocated stack.
