Subject: [PATCH] net: bgmac: fix BCM5358 support by setting correct flags
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Code blocks handling BCMA_CHIP_ID_BCM5357 and BCMA_CHIP_ID_BCM53572 were
incorrectly unified. Chip package values are not unique and cannot be
checked independently. They are meaningful only in a context of a given
chip.
Packages BCM5358 and BCM47188 share the same value but then belong to
different chips. Code unification resulted in treating BCM5358 as
BCM47188 and broke its initialization.

From 5544e90c81261e82e02bbf7c6015a4b9c8c825ef Mon Sep 17 00:00:00 2001
From: Gaosheng Cui <cuigaosheng1@huawei.com>
Date: Fri, 16 Sep 2022 13:20:50 +0100
Subject: [PATCH] nvmem: core: add error handling for dev_set_name
The type of return value of dev_set_name is int, which may return
wrong result, so we add error handling for it to reclaim memory
of nvmem resource, and return early when an error occurs.

From a621c4fdc7e1ef6b9aabe083d57bf6a637fdaf76 Mon Sep 17 00:00:00 2001

Subject: [PATCH] net: Remove WARN_ON_ONCE(sk->sk_forward_alloc) from
sk_stream_kill_queues().
commit 62ec33b44e0f7168ff2886520fec6fb62d03b5a3 upstream.
Christoph Paasch reported that commit b5fc29233d28 ("inet6: Remove
inet6_destroy_sock() in sk->sk_prot->destroy().") started triggering
WARN_ON_ONCE(sk->sk_forward_alloc) in sk_stream_kill_queues(). [0 - 2]
Also, we can reproduce it by a program in [3].
In the commit, we delay freeing ipv6_pinfo.pktoptions from sk->destroy()
to sk->sk_destruct(), so sk->sk_forward_alloc is no longer zero in
inet_csk_destroy_sock().
The same check has been in inet_sock_destruct() from at least v2.6,
we can just remove the WARN_ON_ONCE(). However, among the users of
sk_stream_kill_queues(), only CAIF is not calling inet_sock_destruct().
Thus, we add the same WARN_ON_ONCE() to caif_sock_destructor().
