dpaa_eth: Fix missing of_node_put in dpaa_get_ts_info()

2022-04-11T11:02:33+00:00

Both of of_get_parent() and of_parse_phandle() return node pointer with refcount incremented, use of_node_put() on it to decrease refcount when done. Reported-by: Zeal Robot Signed-off-by: Lv Ruyi Signed-off-by: David S. Miller

bpf: Let bpf_warn_invalid_xdp_action() report more info

2021-12-13T21:28:27+00:00

In non trivial scenarios, the action id alone is not sufficient to identify the program causing the warning. Before the previous patch, the generated stack-trace pointed out at least the involved device driver. Let's additionally include the program name and id, and the relevant device name. If the user needs additional infos, he can fetch them via a kernel probe, leveraging the arguments added here.

net: annotate accesses to queue->trans_start

In following patches, dev_watchdog() will no longer stop all queues. It will read queue->trans_start locklessly. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

ethernet: constify references to netdev->dev_addr in drivers

2021-10-14T16:22:11+00:00

This big patch sprinkles const on local variables and function arguments which may refer to netdev->dev_addr. Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers. Some of the changes here are not strictly required - const is sometimes cast off but pointer is not used for writing. It seems like it's still better to add the const in case the code changes later or relevant -W flags get enabled for the build. No functional changes.

dev_ioctl: split out ndo_eth_ioctl

2021-07-27T19:11:45+00:00

Most users of ndo_do_ioctl are ethernet drivers that implement the MII commands SIOCGMIIPHY/SIOCGMIIREG/SIOCSMIIREG, or hardware timestamping with SIOCSHWTSTAMP/SIOCGHWTSTAMP. Separate these from the few drivers that use ndo_do_ioctl to implement SIOCBOND, SIOCBR and SIOCWANDEV commands. This is a purely cosmetic change intended to help readers find their way through the implementation.

freescale: Remove rcu_read_lock() around XDP program invocation

2021-06-24T17:44:17+00:00

The dpaa and dpaa2 drivers have rcu_read_lock()/rcu_read_unlock() pairs around XDP program invocations. However, the actual lifetime of the objects referred by the XDP program invocation is longer, all the way through to the call to xdp_do_flush(), making the scope of the rcu_read_lock() too small. This turns out to be harmless because it all happens in a single NAPI poll cycle (and thus under local_bh_disable()), but it makes the rcu_read_lock() misleading. Rather than extend the scope of the rcu_read_lock(), just get rid of it entirely. With the addition of RCU annotations to the XDP_REDIRECT map types that take bh execution into account, lockdep even understands this to be safe, so there's really no reason to keep it around.
