2021-10-25s390/qeth: don't keep track of Input Queue countJulian Wiedmann
The only actual user of qdio.no_input_queues is qeth_qdio_establish(), and there we already have full awareness of the current Input Queue configuration (1 RX queue, plus potentially 1 TX Completion queue). So avoid this state tracking, and the ambiguity it brings with it. Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-10-25s390/qeth: clarify remaining dev_kfree_skb_any() usersJulian Wiedmann
For none of the users we are under risk of running in HW IRQ context or or with IRQs disabled. Thus we always end up in consume_skb(). But the two occurences in the RX path should really report the dropped packet to dropmon, so have them use kfree_skb() instead. That's also consistent with what napi_free_frags() does internally.

2021-10-25s390/qeth: move qdio's QAOB cache into qethJulian Wiedmann
qdio.ko no longer needs to care about how the QAOBs are allocated, from its perspective they are merely another parameter to do_QDIO(). So for a start, shift the cache into the only qdio driver that uses QAOBs (ie. qeth). Here there's further opportunity to optimize its usage in the future - eg. make it per-{device, TX queue}, or only compile it when the driver is built with CQ/QAOB support.

2021-10-25s390/qeth: remove .do_ioctl() callback from driver disciplineJulian Wiedmann
With commit 18787eeebd71 ("qeth: use ndo_siocdevprivate") this callback is now actually used to handle transport mode-specific _private_ ioctls. We only have such ioctls for L3 devices. So wire up a L3-specific .ndo_siocdevprivate() callback that handles those ioctls, and defers to the core qeth_siocdevprivate() for all other private ioctls. This takes the discipline one step closer to its original purpose of providing an internal extension for the qeth_core_ccwgroup_driver.

In order to better track where in the kernel the dma-buf code is used, put the symbols in the namespace DMA_BUF and modify all users of the symbols to properly import the namespace to not break the build at the same time.

2021-10-25net: dsa: lantiq_gswip: serialize access to the PCE registersVladimir Oltean
The GSWIP switch accesses various bridging layer tables (VLANs, FDBs, forwarding rules) indirectly through PCE registers. These hardware accesses are non-atomic, being comprised of several register reads and writes. These accesses are currently serialized by the rtnl_lock, but DSA is changing its driver API and that lock will no longer be held when calling ->port_fdb_add() and ->port_fdb_del(). So this driver needs to serialize the access to the PCE registers using its own locking scheme. This patch adds that. Note that the driver also uses the gswip_pce_load_microcode() function to load a static configuration for the packet classification engine into a table using the same registers. It is currently not protected, but since that configuration is only done from the dsa_switch_ops :: setup method, there is no risk of it being concurrent with other operations.

2021-10-25net: dsa: b53: serialize access to the ARL tableVladimir Oltean
The b53 driver performs non-atomic transactions to the ARL table when adding, deleting and reading FDB and MDB entries. Traditionally these were all serialized by the rtnl_lock(), but now it is possible that DSA calls ->port_fdb_add and ->port_fdb_del without holding that lock. So the driver must have its own serialization logic. Add a mutex and hold it from all entry points (->port_fdb_{add,del,dump}, ->port_mdb_{add,del}).

DSA would like to remove the rtnl_lock from its SWITCHDEV_FDB_{ADD,DEL}_TO_DEVICE handlers, and the felix driver uses the same MAC table functions as ocelot. This means that the MAC table functions will no longer be implicitly serialized with respect to each other by the rtnl_mutex, we need to add a dedicated lock in ocelot for the non-atomic operations of selecting a MAC table row, reading/writing what we want and polling for completion.

2021-10-25net: dsa: sja1105: serialize access to the dynamic config interfaceVladimir Oltean
The sja1105 hardware seems as concurrent as can be, but when we create a background script that adds/removes a rain of FDB entries without the rtnl_mutex taken, then in parallel we do another operation like run 'bridge fdb show', we can notice these errors popping up: sja1105 spi2.0: port 2 failed to read back entry for 00:01:02:03:00:40 vid 0: -ENOENT sja1105 spi2.0: port 2 failed to add 00:01:02:03:00:40 vid 0 to fdb: -2 sja1105 spi2.0: port 2 failed to read back entry for 00:01:02:03:00:46 vid 0: -ENOENT sja1105 spi2.0: port 2 failed to add 00:01:02:03:00:46 vid 0 to fdb: -2 Luckily what is going on does not require a major rework in the driver. The sja1105_dynamic_config_read() function sends multiple SPI buffers to the peripheral until the operation completes. We should not do anything until the hardware clears the VALID bit. But since there is no locking (i.e. right now we are implicitly serialized by the rtnl_mutex, but if we remove that), it might be possible that the process which performs the dynamic config read is preempted and another one performs a dynamic config write. What will happen in that case is that sja1105_dynamic_config_read(), when it resumes, expects to see VALIDENT set for the entry it reads back. But it won't. This can be corrected by introducing a mutex for serializing SPI accesses to the dynamic config interface which should be atomic with respect to each other.

2021-10-25net: dsa: sja1105: wait for dynamic config command completion on writes tooVladimir Oltean
The hardware manual says that software should attempt a new dynamic config access (be it a a write or a read-back) only while the VALID bit is cleared. The VALID bit is set by software to 1, and it remains set as long as the hardware is still processing the request. Currently the driver only polls for the command completion only for reads, because that's when we need the actual data read back. Writes have been more or less "asynchronous", although this has never been an observable issue. This change makes sja1105_dynamic_config_write poll the VALID bit as well, to absolutely ensure that a follow-up access to the static config finds the VALID bit cleared. So VALID means "work in progress", while VALIDENT means "entry being read is valid". On reads we check the VALIDENT bit too, while on writes that bit is not always defined. So we need to factor it out of the loop, and make the loop provide back the unpacked command structure, so that sja1105_dynamic_config_read can check the VALIDENT bit. The change also attempts to convert the open-coded loop to use the read_poll_timeout macro, since I know this will come up during review. It's more code, but hey, it uses read_poll_timeout!

2021-10-25irq: arm: perform irqentry in entry codeMark Rutland
In preparation for removing HANDLE_DOMAIN_IRQ_IRQENTRY, have arch/arm perform all the irqentry accounting in its entry code. For configurations with CONFIG_GENERIC_IRQ_MULTI_HANDLER, we can use generic_handle_arch_irq(). Other than asm_do_IRQ(), all C calls to handle_IRQ() are from irqchip handlers which will be called from generic_handle_arch_irq(), so to avoid double accounting IRQ entry, the entry logic is moved from handle_IRQ() into asm_do_IRQ(). For ARMv7M the entry assembly is tightly coupled with the NVIC irqchip, and while the entry code should logically live under arch/arm/, moving the entry logic there makes things more convoluted. So for now, place the entry logic in the NVIC irqchip, but separated into a separate function to make the split of responsibility clear. For all other configurations without CONFIG_GENERIC_IRQ_MULTI_HANDLER, IRQ entry is already handled in arch code, and requires no changes. There should be no functional change as a result of this patch.

2021-10-25irq: mips: avoid nested irq_enter()Mark Rutland
As bcm6345_l1_irq_handle() is a chained irqchip handler, it will be invoked within the context of the root irqchip handler, which must have entered IRQ context already. When bcm6345_l1_irq_handle() calls arch/mips's do_IRQ() , this will nest another call to irq_enter(), and the resulting nested increment to `rcu_data.dynticks_nmi_nesting` will cause rcu_is_cpu_rrupt_from_idle() to fail to identify wakeups from idle, resulting in failure to preempt, and RCU stalls. Chained irqchip handlers must invoke IRQ handlers by way of thee core irqchip code, i.e. generic_handle_irq() or generic_handle_domain_irq() and should not call do_IRQ(), which is intended only for root irqchip handlers. Fix bcm6345_l1_irq_handle() by calling generic_handle_irq() directly.

Currently the dwc2 doesn't fill in the 'otg_caps' of usb_gadget structure. When registering a gadget device (e.g. via configfs), the usb_otg_descriptor_init() checks the 'otg_caps' and 'otg_rev'. It defaults to HNP and SRP bmAttributes if unspecified. There may be a mismatch with what's being set in dwc2 params structure. This result in the descriptors to be miss-configured in this case. So replace 'otg_cap' bit field by 'otg_caps' structure, so hnp, srp and otg_rev' can be configured directly in the params. It's then provided to the gadget struct. These parameters can be tuned for each platform. In case it's not set, it will default to current behavior. Also add option to setup these from the device tree by calling of_usb_update_otg_caps(). This provides support for standard properties such as "otg-rev", "hnp-disable" and "srp-disable" (see usb-drd.yaml).

2021-10-25staging: vchiq_core.h: fix CamelCase in function declarationGaston Gonzalez
Renaming function declaration to avoid CamelCase use. As this was already fixed in the function definition in commit 801b1aa002d3 ("staging: vc04_services: fix CamelCase"), the current change make the names of the variables in the function definition and declartion match.

2021-10-25staging: r8188eu: remove the sreset_priv structureMartin Kaiser
last_tx_time from struct sreset_priv is no longer used now that last_tx_complete_time is gone. This patch removes last_tx_time. This was the last remaining component of struct sreset_priv, we can now remove the structure itself. After removing include/rtw_sreset.h, it turned out that some definitions in .c files were pulled in via rtw_sreset.h. Add the required include files directly to make compilation succeed without rtw_sreset.h.

2021-10-25ata: sata_mv: Fix the error handling of mv_chip_id()Zheyu Ma
mv_init_host() propagates the value returned by mv_chip_id() which in turn gets propagated by mv_pci_init_one() and hits local_pci_probe(). During the process of driver probing, the probe function should return < 0 for failure, otherwise, the kernel will treat value > 0 as success. Since this is a bug rather than a recoverable runtime error we should use dev_alert() instead of dev_err().
