ceph_msgpool_get() can fall back to ceph_msg_new() when it is asked for a message whose front portion is larger than pool->front_len. However the caller always passes 0, effectively disabling that code path. The allocation goes to the message pool and returns a message with a front that is smaller than requested, setting us up for a crash. One example of this is a directory with a large number of snapshots. If its snap context doesn't fit, we oops in encode_request_partial(). Signed-off-by: Ilya Dryomov <idryomov@gmail.com> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
