[ Upstream commit 7a0ea70da56ee8c2716d0b79e9959d3c47efab62 ]
Commit 43645ce03e00 ("qed: Populate nvm image attribute shadow.")
added support for populating flash image attributes, notably
"num_images". However, some cards were not able to return this
information. In such cases, the driver would return EINVAL, causing the
driver to exit.
Add check to return EOPNOTSUPP instead of EINVAL when the card is not
able to return these information. The caller function already handles
EOPNOTSUPP without error.
Fixes: 43645ce03e00 ("qed: Populate nvm image attribute shadow.")

This patch improves the stack space of qede_config_rx_mode() by
splitting filter_config() to 3 functions and removing the
union qed_filter_type_params.

clang complains that the temporary string for the name passed into
alloc_workqueue() is too short for its contents:
drivers/net/ethernet/qlogic/qed/qed_main.c:1218:3: error: 'snprintf' will always be truncated; specified size is 16, but format string expands to at least 18 [-Werror,-Wformat-truncation]
There is no need for a temporary buffer, and the actual name of a workqueue
is 32 bytes (WQ_NAME_LEN), so just use the interface as intended to avoid
the truncation.

When calling qede_parse_actions() then the
return code was only used for a non-zero check,
and then -EINVAL was returned.
qede_parse_actions() can currently fail with:
* -EINVAL
* -EOPNOTSUPP
This patch changes the code to use the actual
return code, not just return -EINVAL.
The blaimed commit broke the implicit assumption
that only -EINVAL would ever be returned.

Explicitly set 'rc' (return code), before jumping to the
unlock and return path.
By not having any code depend on that 'rc' remains at
it's initial value of -EINVAL, then we can re-use 'rc' for
the return code of function calls in subsequent patches.

qed_ilt_shadow_alloc() will call qed_ilt_shadow_free() to
free p_hwfn->p_cxt_mngr->ilt_shadow on error. However,
qed_cxt_tables_alloc() accesses the freed pointer on failure
of qed_ilt_shadow_alloc() through calling qed_cxt_mngr_free(),
which may lead to use-after-free. Fix this issue by setting
p_mngr->ilt_shadow to NULL in qed_ilt_shadow_free().

Similar to skb_eth_hdr() introduced in commit 96cc4b69581d ("macvlan: do
not assume mac_header is set in macvlan_broadcast()"), let's introduce a
skb_vlan_eth_hdr() helper which can be used in TX-only code paths to get
to the VLAN header based on skb->data rather than based on the
skb_mac_header(skb).
We also consolidate the drivers that dereference skb->data to go through
this helper.

commit 2f3389c73832ad90b63208c0fc281ad080114c7a upstream.
Driver allocates the LL2 rx buffers from kmalloc()
area to construct the skb using slab_build_skb()
The required size allocation seems to have overlooked
for accounting both skb_shared_info size and device
placement padding bytes which results into the below
panic when doing skb_put() for a standard MTU sized frame.
