Dinghao Liu 9fc81912fc net: bnxt: fix a potential use-after-free in bnxt_init_tc
[ Upstream commit d007caaaf052f82ca2340d4c7b32d04a3f5dbf3f ]

When flow_indr_dev_register() fails, bnxt_init_tc will free
bp->tc_info through kfree(). However, the caller function
bnxt_init_one() will ignore this failure and call
bnxt_shutdown_tc() on failure of bnxt_dl_register(), where
a use-after-free happens. Fix this issue by setting
bp->tc_info to NULL after kfree().

README

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.

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.
