Callers of cfg80211_unregister_wdev can free the wdev object immediately after this function returns. This may crash the kernel because this wdev object is still in use by other threads. Add synchronize_rcu() after list_del_rcu to make sure wdev object can be safely freed. Signed-off-by: Dedy Lansky <dlansky@codeaurora.org> Signed-off-by: Johannes Berg <johannes@sipsolutions.net>
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.
