Ido Schimmel says: ==================== mlxsw: Fix ACL actions error condition handling Nir says: Two issues were lately noticed within mlxsw ACL actions error condition handling. The first patch deals with conflicting actions such as: # tc filter add dev swp49 parent ffff: \ protocol ip pref 10 flower skip_sw dst_ip 192.168.101.1 \ action goto chain 100 \ action mirred egress redirect dev swp4 The second action will never execute, however SW model allows this configuration, while the mlxsw driver cannot allow for it as it implements actions in sets of up to three actions per set with a single termination marking. Conflicting actions create a contradiction over this single marking and thus cannot be configured. The fix replaces a misplaced warning with an error code to be returned. Patches 2-4 fix a condition of duplicate destruction of resources. Some actions require allocation of specific resource prior to setting the action itself. On error condition this resource was destroyed twice, leading to a crash when using mirror action, and to a redundant destruction in other cases, since for error condition rule destruction also takes care of resource destruction. In order to fix this state a symmetry in behavior is added and resource destruction also takes care of removing the resource from rule's resource list. ==================== Signed-off-by: David S.

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.
