While CHELSIO_INLINE_CRYPTO is a guard symbol, and just enabling it does not cause any additional code to be compiled in, all configuration options protected by it depend on CONFIG_CHELSIO_T4. Hence it doesn't make much sense to bother the user with the guard symbol question when CONFIG_CHELSIO_T4 is disabled. Fix this by moving the dependency from the individual config options to the guard symbol.

Russell King says: ==================== Convert mvpp2 to split PCS support This series converts the mvpp2 driver to use the split PCS support that has been merged into phylink last time around. I've been running this for some time here and, apart from the recent bug fix sent to net-next, have not seen any issues on DT based systems. I have not tested ACPI setups, although I've tried to preserve the workaround. Patch 1 formalises the ACPI workaround. Patch 2 moves some of mac_config() to the mac_prepare() and mac_finish() callbacks so we can keep the ordering when we split the PCS bits out. Patch 3 ensures that the port is forced down while changing the interface mode - when in in-band mode, doing this in mac_prepare() and mac_finish(). Patch 4 moves the reset handling to mac_prepare() and mac_finish() Patch 5 does a straight conversion to use PCS operations. Patch 6 splits the PCS operations into a GMAC PCS operations and XLG PCS operations, selecting the appropriate set during mac_prepare(). This eliminates a bunch of conditionals from the code. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

l2tp_tunnel_closeall is called as a part of tunnel shutdown in order to close all the sessions held by the tunnel. The code it uses to close a session duplicates what l2tp_session_delete does. Rather than duplicating the code, have l2tp_tunnel_closeall call l2tp_session_delete instead. This involves a very minor change to locking in l2tp_tunnel_closeall. Previously, l2tp_tunnel_closeall checked the session "dead" flag while holding tunnel->hlist_lock. This allowed for the code to step to the next session in the list without releasing the lock if the current session happened to be in the process of closing already. By calling l2tp_session_delete instead, l2tp_tunnel_closeall must now drop and regain the hlist lock for each session in the tunnel list. Given that the likelihood of a session being in the process of closing when the tunnel is closed, it seems worth this very minor potential loss of efficiency to avoid duplication of the session delete code.

The l2tp tunnel and session structures contain a "magic feather" field which was originally intended to help trace lifetime bugs in the code. Since the introduction of the shared kernel refcount code in refcount.h, and l2tp's porting to those APIs, we are covered by the refcount code's checks and warnings. Duplicating those checks in the l2tp code isn't useful. However, magic feather checks are still useful to help to detect bugs stemming from misuse/trampling of the sk_user_data pointer in struct sock. The l2tp code makes extensive use of sk_user_data to stash pointers to the tunnel and session structures, and if another subsystem overwrites sk_user_data it's important to detect this. As such, rework l2tp's magic feather checks to focus on validating the tunnel and session data structures when they're extracted from sk_user_data. * Add a new accessor function l2tp_sk_to_tunnel which contains a magic feather check, and is used by l2tp_core and l2tp_ip[6] * Comment l2tp_udp_encap_recv which doesn't use this new accessor function because of the specific nature of the codepath it is called in * Drop l2tp_session_queue_purge's check on the session magic feather: it is called from code which is walking the tunnel session list, and hence doesn't need validation * Drop l2tp_session_free's check on the tunnel magic feather: the intention of this check is covered by refcount.h's reference count sanity checking * Add session magic validation in pppol2tp_ioctl. On failure return -EBADF, which mirrors the approach in pppol2tp_[sg]etsockopt. Signed-off-by: Tom Parkin <tparkin@katalix.com> Signed-off-by: David S. Miller <davem@davemloft.net>

l2tp_xmit_skb has a number of failure paths which are not reflected in the tunnel and session statistics because the stats are updated by l2tp_xmit_core. Hence any errors occurring before l2tp_xmit_core is called are missed from the statistics. Refactor the transmit path slightly to capture all error paths. l2tp_xmit_skb now leaves all the actual work of transmission to l2tp_xmit_core, and updates the statistics based on l2tp_xmit_core's return code.

All callers pass the session structure's hdr_len field as the header length parameter to l2tp_xmit_skb.

Paul Barker says: ==================== Minor improvements to b53 dmesg output These changes were made while debugging the b53 driver for use on a custom board. They've been runtime tested on a patched 4.14.y kernel which supports this board as well as build tested with 5.9-rc3. The changes are straightforward enough that I think this testing is sufficient but let me know if further testing is required. Unfortunately I don't have a board to hand which boots with a more recent kernel and has a switch supported by the b53 driver. I'd still like to upstream these patches if possible though. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Linus Walleij says: ==================== RTL8366 stabilization This stabilizes the RTL8366 driver by checking validity of the passed VLANs and refactoring the member config (MC) code so we do not require strict call order and de-duplicate some code.

Linus Walleij authored
The VLANs and PVIDs on the RTL8366 utilizes a "member configuration" (MC) which is largely unexplained in the code. This set-up requires a special ordering: rtl8366_set_pvid() must be called first, followed by rtl8366_set_vlan(), else the MC will not be properly allocated. Relax this by factoring out the code obtaining an MC and reuse the helper in both rtl8366_set_pvid() and rtl8366_set_vlan() so we remove this strict ordering requirement. In the process, add some better comments and debug prints so people who read the code understand what is going on.
