Gustavo A. R. Silva says: ==================== netrom: refactor code and mark expected switch fall-throughs The aim of this patchset is firstly to refactor code in nr_route.c in order to make it easier to read and maintain and, secondly, to mark some expected switch fall-throughs in preparation to enabling -Wimplicit-fallthrough. I have to mention that I did not implement any unit test. If someone has any suggestions on how I could test this piece of code it'd be greatly appreciated. Changes in v2: - Make use of the swap macro and remove inline keyword as suggested by Walter Harms and Kevin Dawson. Changes in v3: - Update subject for both patches. - Add this cover letter as suggested by David Miller. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

During perf event attaching/detaching bpf programs, the tp_event->prog_array change is protected by the bpf_event_mutex lock in both attaching and deteching functions. Although tp_event->prog_array is a rcu pointer, rcu_derefrence is not needed to access it since mutex lock will guarantee ordering. Verified through "make C=2" that sparse locking check still happy with the new change. Also change the label name in perf_event_{attach,detach}_bpf_prog from "out" to "unlock" to reflect the code action after the label.

Antoine Tenart says: ==================== net: mvpp2: various improvements This series includes various patches improving the Marvell PPv2 driver. I send them as a series to avoid any possible merge conflict. - Patches 1 and 2 improve the initializing of the Tx and Rx FIFO. - Patch 3 initialize the RSS table to evenly distribute the ingress packets across multiple Rx queues based on their hashes. - Patch 4 limits the number of TSO segments sent to the driver, to avoid having more segments to handle than the corresponding number of available descriptors. - Patch 5 and 6 are cosmetic improvements. This applies on today's net-next branch, The patches were tested extensively (I ran iperf and http downloads in parallel, transferring TBs of data). ==================== Signed-off-by: NDavid S.

Two functions were always used to set the DMA addresses in Tx descriptors, because this address is split into a base+offset in the descriptors. A mask was used to come up with the base and offset addresses and two functions were called, mvpp2_txdesc_dma_addr_set() and mvpp2_txdesc_offset_set(). This patch moves the base+offset calculation logic to mvpp2_txdesc_dma_addr_set(), and removes mvpp2_txdesc_offset_set() to simplify things.

Too many TSO descriptors can be required for the default queue size, when using small MSS values for example. Prevent this by adding a maximum number of allowed TSO segments (300). In addition set a stop and a wake thresholds to stop the queue when there's no room for a 1 "worst case scenario skb". Wake up the queue when the number of descriptors is low enough.

David Ahern says: ==================== net: Allow non-fatal messages to be passed in extack There are many cases where networking subsystems throw non-fatal warning messages that end up in dmesg / kernel log to which a user making the change is completely oblivious. This set makes the extack facility usable for returning such messages. The case in point here is spectrum and adding FIB rules which causes an offload abort. Make the use case more user friendly by letting the user know that offload is no longer happening because of the rule change. v2 - kept the offload abort in a work queue entry per Ido's comment ==================== Signed-off-by: NDavid S.

Adding a FIB rule on a spectrum platform silently aborts FIB offload: $ ip ru add pref 99 from all to 192.168.1.1 table 10 $ dmesg -c [ 623.144736] mlxsw_spectrum 0000:03:00.0: FIB abort triggered. Note that FIB entries are no longer being offloaded to this device. This patch reworks FIB rule handling to return a message to the user: $ ip ru add pref 99 from all to 8.8.8.8 table 11 Error: spectrum: FIB rules not supported. Aborting offload. spectrum currently only checks whether the fib rule is a default rule or an l3mdev rule, both of which it knows how to handle. Any other it aborts FIB offload. Move the processing to check the rule type inline with the user request. If the rule is an unsupported one, then a work queue entry is used to abort the offload. Change the rule delete handling to just return since it does nothing at the moment.

There is no point into hiding the -EINVAL error code in ERR_PTR from a dsa_get_ports function, simply get the "ports" node directly from within the dsa_parse_ports_dn function. This also has the effect to make the pdata and device tree handling code symmetrical inside _dsa_register_switch. At the same time, rename dsa_parse_ports_dn to dsa_parse_ports_of because _of is a more common suffix for device tree parsing functions.

the verifier got progressively smarter over time and size of its internal state grew as well. Time to reduce the memory consumption. Before: sizeof(struct bpf_verifier_state) = 6520 After: sizeof(struct bpf_verifier_state) = 896 It's done by observing that majority of BPF programs use little to no stack whereas verifier kept all of 512 stack slots ready always. Instead dynamically reallocate struct verifier state when stack access is detected. Runtime difference before vs after is within a noise. The number of processed instructions stays the same.
