2021-02-08brcmsmac: fix alignment constraintsArnd Bergmann
sturct d11txh contains a ieee80211_rts structure, which is required to have at least two byte alignment, and this conflicts with the __packed attribute: drivers/net/wireless/broadcom/brcm80211/brcmsmac/d11.h:786:1: warning: alignment 1 of 'struct d11txh' is less than 2 [-Wpacked-not-aligned] Mark d11txh itself as having two-byte alignment to ensure the inner structure is properly aligned.

2021-02-08brcmfmac: Add DMI nvram filename quirk for Voyo winpad A15 tabletHans de Goede
The Voyo winpad A15 tablet contains quite generic names in the sys_vendor and product_name DMI strings, without this patch brcmfmac will try to load: rcmfmac4330-sdio.To be filled by O.E.M.-To be filled by O.E.M..txt as nvram file which is a bit too generic. Add a DMI quirk so that a unique and clearly identifiable nvram file name is used on the Voyo winpad A15 tablet. While preparing a matching linux-firmware update I noticed that the nvram is identical to the nvram used on the Prowise-PT301 tablet, so the new DMI quirk entry simply points to the already existing Prowise-PT301 nvram file.

2021-02-08rtlwifi: use tasklet_setup to initialize rx_work_taskletEmil Renner Berthing
In commit d3ccc14dfe95 most of the tasklets in this driver was updated to the new API. However for the rx_work_tasklet only the type of the callback was changed from void _rtl_rx_work(unsigned long data) to void _rtl_rx_work(struct tasklet_struct *t). The initialization of rx_work_tasklet was still open-coded and the function pointer just cast into the old type, and hence nothing sets rx_work_tasklet.use_callback = true and the callback was still called as t->func(t->data); with uninitialized/zero t->data. Commit 6b8c7574a5f8 changed the casting of _rtl_rx_work a bit and initialized t->data to a pointer to the tasklet cast to an unsigned long. This way calling t->func(t->data) might actually work through all the casting, but it still doesn't update the code to use the new tasklet API. Let's use the new tasklet_setup to initialize rx_work_tasklet properly and set rx_work_tasklet.use_callback = true so that the callback is called as t->callback(t); without all the casting.

2021-02-08USB: serial: option: update interface mapping for ZTE P685MLech Perczak
This patch prepares for qmi_wwan driver support for the device. Previously "option" driver mapped itself to interfaces 0 and 3 (matching ff/ff/ff), while interface 3 is in fact a QMI port. Interfaces 1 and 2 (matching ff/00/00) expose AT commands, and weren't supported previously at all. Without this patch, a possible conflict would exist if device ID was added to qmi_wwan driver for interface 3. Update and simplify device ID to match interfaces 0-2 directly, to expose QCDM (0), PCUI (1), and modem (2) ports and avoid conflict with QMI (3), and ADB (4). The modem is used inside ZTE MF283+ router and carriers identify it as such. Interface mapping is: 0: QCDM, 1: AT (PCUI), 2: AT (Modem), 3: QMI, 4: ADB T: Bus=02 Lev=02 Prnt=02 Port=05 Cnt=01 Dev#= 3 Spd=480 MxCh= 0 D: Ver= 2.01 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=19d2 ProdID=1275 Rev=f0.00 S: Manufacturer=ZTE,Incorporated S: Product=ZTE Technologies MSM S: SerialNumber=P685M510ZTED0000CP&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&0 C:* #Ifs= 5 Cfg#= 1 Atr=a0 MxPwr=500mA I:* If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.)

2021-02-06net/vmw_vsock: improve locking in vsock_connect_timeout()Norbert Slusarek
A possible locking issue in vsock_connect_timeout() was recognized by Eric Dumazet which might cause a null pointer dereference in vsock_transport_cancel_pkt(). This patch assures that vsock_transport_cancel_pkt() will be called within the lock, so a race condition won't occur which could result in vsk->transport to be set to NULL.

In vsock_stream_connect(), a thread will enter schedule_timeout(). While being scheduled out, another thread can enter vsock_stream_connect() as well and set vsk->transport to NULL. In case a signal was sent, the first thread can leave schedule_timeout() and vsock_transport_cancel_pkt() will be called right after. Inside vsock_transport_cancel_pkt(), a null dereference will happen on transport->cancel_pkt.

2021-02-06net/packet: Improve the comment about LL header visibility criteriaXie He
The "dev_has_header" function, recently added in commit d549699048b4 ("net/packet: fix packet receive on L3 devices without visible hard header"), is more accurate as criteria for determining whether a device exposes the LL header to upper layers, because in addition to dev->header_ops, it also checks for dev->header_ops->create. When transmitting an skb on a device, dev_hard_header can be called to generate an LL header. dev_hard_header will only generate a header if dev->header_ops->create is present.

Alex Elder says: ==================== net: ipa: a mix of small improvements Version 2 of this series restructures a couple of the changed functions (in patches 1 and 2) to avoid blocks of indented code by returning early when possible, as suggested by Jakub. The description of the first patch was changed as a result, to better reflect what the updated patch does. It also fixes one spot I identified when updating the code, where gsi_channel_stop() was doing the wrong thing on error. The original description for this series is below. This series contains a sort of unrelated set of code cleanups. The first two are things I wanted to do in a series that updated some NAPI code recently. I didn't want to change things in a way that affected existing testing so I set these aside for later (i.e., now). The third makes a change to event ring handling that's similar to what was done a while back for channels. There's little benefit to cacheing the current state of an event ring, so with this we'll just fetch the state from hardware whenever we need it. The fourth patch removes the definitions of two unused symbols. The fifth replaces a count that is always 0 or 1 with a Boolean. The sixth removes a build-time validation check that doesn't really provide benefit. And the last one fixes a problem (in two spots) that could cause a build-time check to fail "bogusly". ==================== Link: https://lore.kernel.org/r/20210205221100.1738-1-elder@linaro.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2021-02-06net: ipa: avoid field overflowAlex Elder
It's possible that the length passed to ipa_header_size_encoded() is larger than what can be represented by the HDR_LEN field alone (starting with IPA v4.5). If we attempted that, u32_encode_bits() would trigger a build-time error. Avoid this problem by masking off high-order bits of the value encoded as the lower portion of the header length. The same sort of problem exists in ipa_metadata_offset_encoded(), so implement the same fix there. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2021-02-06net: ipa: do not cache event ring stateAlex Elder
An event ring's state only needs to be known when it is allocated, reset, or deallocated. We check an event ring's state both before and after performing an event ring control command that changes its state. These are only issued at startup and shutdown, so there is very little value in caching the state. Stop recording a copy of the channel's last known state, and instead fetch the true state from hardware whenever it's needed. In such cases, *do* record the state in a local variable, in case an error message reports it (so the value reported is the value seen).

2021-02-06net: ipa: synchronize NAPI only for suspendAlex Elder

2021-02-06net: dsa: make assisted_learning_on_cpu_port bypass offloaded LAG interfacesVladimir Oltean
Given the following topology, and focusing only on Box A: Box A +----------------------------------+ | Board 1 br0 | | +---------+ | | / \ | | | | | | | bond0 | | | +-----+ | |192.168.1.1 | / \ | | eno0 swp0 swp1 swp2 | +---|--------|-------|-------|-----+ | | | | +--------+ | | Cable | | Cable| |Cable Cable | | +--------+ | | | | | | +---|--------|-------|-------|-----+ | eno0 swp0 swp1 swp2 | |192.168.1.2 | \ / | | | +-----+ | | | bond0 | | | | | | \ / | | +---------+ | | Board 2 br0 | +----------------------------------+ Box B The assisted_learning_on_cpu_port logic will see that swp0 is bridged with a "foreign interface" (bond0) and will therefore install all addresses learnt by the software bridge towards bond0 (including the address of eno0 on Box B) as static addresses towards the CPU port. But that's not what we want - bond0 is not really a "foreign interface" but one we can offload including L2 forwarding from/towards it. So we need to refine our logic for assisted learning such that, whenever we see an address learnt on a non-DSA interface, we search through the tree for any port that offloads that non-DSA interface. Some confusion might arise as to why we search through the whole tree instead of just the local switch returned by dsa_slave_dev_lower_find. Or a different angle of the same confusion: why does dsa_slave_dev_lower_find(br_dev) return a single dp that's under br_dev instead of the whole list of bridged DSA ports? To answer the second question, it should be enough to install the static FDB entry on the CPU port of a single switch in the tree, because dsa_port_fdb_add uses DSA_NOTIFIER_FDB_ADD which ensures that all other switches in the tree get notified of that address, and add the entry themselves using dsa_towards_port(). This should help understand the answer to the first question: the port returned by dsa_slave_dev_lower_find may not be on the same switch as the ports that offload the LAG. Nonetheless, if the driver implements .crosschip_lag_join and .crosschip_bridge_join as mv88e6xxx does, there still isn't any reason for trapping addresses learnt on the remote LAG towards the CPU, and we should prevent that.

2021-02-06net: mscc: ocelot: rebalance LAGs on link up/down eventsVladimir Oltean
At present there is an issue when ocelot is offloading a bonding interface, but one of the links of the physical ports goes down. Traffic keeps being hashed towards that destination, and of course gets dropped on egress. Monitor the netdev notifier events emitted by the bonding driver for changes in the physical state of lower interfaces, to determine which ports are active and which ones are no longer. Then extend ocelot_get_bond_mask to return either the configured bonding interfaces, or the active ones, depending on a boolean argument. The code that does rebalancing only needs to do so among the active ports, whereas the bridge forwarding mask and the logical port IDs still need to look at the permanently bonded ports.
