DSA network devices rely on having their DSA management interface up and running otherwise their ndo_open() will return -ENETDOWN. Without doing this it would not be possible to use DSA devices as netconsole when configured on the command line. These devices also do not utilize the upper/lower linking so the check about the netpoll device having upper is not going to be a problem. The solution adopted here is identical to the one done for net/ipv4/ipconfig.c with 728c0208 ("net: ipv4: handle DSA enabled master network devices"), with the network namespace scope being restricted to that of the process configuring netpoll. Fixes: 04ff53f9 ("net: dsa: Add netconsole support") Tested-by:

Due to a hardware issue, an access to MDIO registers that is concurrent with other ENETC register accesses may lead to the MDIO access being dropped or corrupted. The workaround introduces locking for all register accesses to the ENETC register space. To reduce performance impact, a readers-writers locking scheme has been implemented. The writer in this case is the MDIO access code (irrelevant whether that MDIO access is a register read or write), and the reader is any access code to non-MDIO ENETC registers. Also, the datapath functions acquire the read lock fewer times and use _hot accessors. All the rest of the code uses the _wa accessors which lock every register access. The commit introducing MDIO support is - commit ebfcb23d ("enetc: Add ENETC PF level external MDIO support") but due to subsequent refactoring this patch is applicable on top of a later commit.

During loss recovery, retransmitted packets are forced to use TCP timestamps to calculate the RTT samples, which have a millisecond granularity. BBR is designed using a microsecond granularity. As a result, multiple RTT samples could be truncated to the same RTT value during loss recovery. This is problematic, as BBR will not enter PROBE_RTT if the RTT sample is <= the current min_rtt sample, meaning that if there are persistent losses, PROBE_RTT will constantly be pushed off and potentially never re-entered. This patch makes sure that BBR enters PROBE_RTT by checking if RTT sample is < the current min_rtt sample, rather than <=. The Netflix transport/TCP team discovered this bug in the Linux TCP BBR code during lab tests. Fixes: 0f8782ea ("tcp_bbr: add BBR congestion control") Signed-off-by:

bnxt_add_one_ctr() adds a hardware counter to a software counter and adjusts for the hardware counter wraparound against the mask. The logic assumes that the hardware counter is always smaller than or equal to the mask. This assumption is mostly correct. But in some cases if the firmware is older and does not provide the accurate mask, the driver can use a mask that is smaller than the actual hardware mask. This can cause some extra carry bits to be added to the software counter, resulting in counters that far exceed the actual value. Fix it by masking the hardware counter with the mask passed into bnxt_add_one_ctr(). Fixes: fea6b333 ("bnxt_en: Accumulate all counters.") Reviewed-by:

Transactions sit on one of several lists, depending on their state (allocated, pending, complete, or polled). A spinlock protects against concurrent access when transactions are moved between these lists. Transactions are also reference counted. A newly-allocated transaction has an initial count of 1; a transaction is released in gsi_trans_free() only if its decremented reference count reaches 0. Releasing a transaction includes removing it from the polled (or if unused, allocated) list, so the spinlock is acquired when we release a transaction. The reference count is used to allow a caller to synchronously wait for a committed transaction to complete. In this case, the waiter takes an extra reference to the transaction *before* committing it (so it won't be freed), and releases its reference (calls gsi_trans_free()) when it is done with it. Similarly, gsi_channel_update() takes an extra reference to ensure a transaction isn't released before the function is done operating on it. Until the transaction is moved to the completed list (by this function) it won't be freed, so this reference is taken "safely." But in the quiesce path, we want to wait for the "last" transaction, which we find in the completed or polled list. Transactions on these lists can be freed at any time, so we (try to) prevent that by taking the reference while holding the spinlock. Currently gsi_trans_free() decrements a transaction's reference count unconditionally, acquiring the lock to remove the transaction from its list *only* when the count reaches 0. This does not protect the quiesce path, which depends on the lock to ensure its extra reference prevents release of the transaction. Fix this by only dropping the last reference to a transaction in gsi_trans_free() while holding the spinlock. Fixes: 9dd441e4 ("soc: qcom: ipa: GSI transactions") Reported-by:

The user reports that switching to PHY scanning instead of configuring the PHY within device-tree works around this issue. The documentation for the standalone variant of the PHY11G (which is probably very similar to what is used inside the xRX200 SoCs but having the firmware burnt onto that standalone chip in the factory) states that the PHY needs 300ms to be ready for MDIO communication after releasing the reset. Add a 300ms delay after initializing all GPHYs to ensure that the GPHY firmware had enough time to initialize and to appear on the MDIO bus. Unfortunately there is no (known) documentation on what the minimum time to wait after releasing the reset on an internal PHY so play safe and take the one for the external variant. Only wait after the last GPHY firmware is loaded to not slow down the initialization too much ( xRX200 has two GPHYs but newer SoCs have at least three GPHYs).

Packets are processed even though the first fragment don't include all headers through the upper layer header. This breaks TAHI IPv6 Core Conformance Test v6LC.1.3.6. Referring to RFC8200 SECTION 4.5: "If the first fragment does not include all headers through an Upper-Layer header, then that fragment should be discarded and an ICMP Parameter Problem, Code 3, message should be sent to the source of the fragment, with the Pointer field set to zero." The fragment needs to be validated the same way it is done in commit 2efdaaaf ("IPv6: reply ICMP error if the first fragment don't include all headers") for ipv6. Wrap the validation into a common function, ipv6_frag_thdr_truncated() to check for truncation in the upper layer header. This validation does not fullfill all aspects of RFC 8200, section 4.5, but is at the moment sufficient to pass mentioned TAHI test. In netfilter, utilize the fragment offset returned by find_prev_fhdr() to let ipv6_frag_thdr_truncated() start it's traverse from the fragment header. Return 0 to drop the fragment in the netfilter. This is the same behaviour as used on other protocol errors in this function, e.g. when nf_ct_frag6_queue() returns -EPROTO. The Fragment will later be picked up by ipv6_frag_rcv() in reassembly.c. ipv6_frag_rcv() will then send an appropriate ICMP Parameter Problem message back to the source.

pm_runtime_get_sync() will increment pm usage at first and it will resume the device later. If runtime of the device has error or device is in inaccessible state(or other error state), resume operation will fail. If we do not call put operation to decrease the reference, it will result in reference count leak. Moreover, this device cannot enter the idle state and always stay busy or other non-idle state later. So we fixed it by replacing it with pm_runtime_resume_and_get.

Colin Ian King's patch fixes a potential integer overflow on shift in the peak_usb driver. The next two patches target the flexcan driver, a patch by me adds the missing "req_bit" to the stop mode property comment (which was broken during net-next for v5.10). Zhang Qilong's patch fixes the failure handling of pm_runtime_get_sync(). The next seven patches target the m_can driver including the tcan4x5x spi driver glue code. Enric Balletbo i Serra's patch for the tcan4x5x Kconfig fix the REGMAP_SPI dependency handling. A patch by me for the tcan4x5x driver's probe() function adds missing error handling to for devm_regmap_init(), and in tcan4x5x_can_remove() the order of deregistration is fixed. Wu Bo's patch for the m_can driver fixes the state change handling in m_can_handle_state_change(). Two patches by Dan Murphy first introduce m_can_class_free_dev() and then make use of it to fix the freeing of the can device. A patch by Faiz Abbas add a missing shutdown of the CAN controller in the m_can_stop() function. * tag 'linux-can-fixes-for-5.10-20201115' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can: can: m_can: m_can_stop(): set device to software init mode before closing can: m_can: Fix freeing of can device from peripherials can: m_can: m_can_class_free_dev(): introduce new function can: m_can: m_can_handle_state_change(): fix state change can: tcan4x5x: tcan4x5x_can_remove(): fix order of deregistration can: tcan4x5x: tcan4x5x_can_probe(): add missing error checking for devm_regmap_init() can: tcan4x5x: replace depends on REGMAP_SPI with depends on SPI can: flexcan: fix failure handling of pm_runtime_get_sync() can: flexcan: flexcan_setup_stop_mode(): add missing "req_bit" to stop mode property comment can: peak_usb: fix potential integer overflow on shift of a int can: mcba_usb: mcba_usb_start_xmit(): first fill skb, then pass to can_put_echo_skb() can: ti_hecc: Fix memleak in ti_hecc_probe can: dev: can_restart(): post buffer from the right context can: af_can: prevent potential access of uninitialized member in canfd_rcv() can: af_can: prevent potential access of uninitialized member in can_rcv() ==================== Link: https://lore.kernel.org/r/20201115174131.2089251-1-mkl@pengutronix.deSigned-off-by:

There might be some requests pending in the buffer when the interface close sequence occurs. In some devices, these pending requests might lead to the module not shutting down properly when m_can_clk_stop() is called. Therefore, move the device to init state before potentially powering it down. Fixes: e0d1f481 ("can: m_can: add Bosch M_CAN controller support") Signed-off-by:
