If driver teardown is called while PCI is turned off, there is a race between health recovery and teardown. If health recovery already started it will wait 60 sec trying to see if PCI gets back and it can recover, but actually there is no need to wait anymore once teardown was called. Use the MLX5_BREAK_FW_WAIT flag which is set on driver teardown to break waiting for PCI up. Signed-off-by:

When shutdown or remove callbacks are called the driver sets the flag MLX5_BREAK_FW_WAIT, to stop waiting for FW as teardown was called. There is no need to clear the bit as once shutdown or remove were called as there is no way back, the driver is going down. Furthermore, if not cleared the flag can be used also in other loops where we may wait while teardown was already called. Use test_bit() instead of test_and_clear_bit() as there is no need to clear the flag. Signed-off-by:

Tony Nguyen says: ==================== ice: refactor mailbox overflow detection Jake Keller says: The primary motivation of this series is to cleanup and refactor the mailbox overflow detection logic such that it will work with Scalable IOV. In addition a few other minor cleanups are done while I was working on the code in the area. First, the mailbox overflow functions in ice_vf_mbx.c are refactored to store the data per-VF as an embedded structure in struct ice_vf, rather than stored separately as a fixed-size array which only works with Single Root IOV. This reduces the overall memory footprint when only a handful of VFs are used. The overflow detection functions are also cleaned up to reduce the need for multiple separate calls to determine when to report a VF as potentially malicious. Finally, the ice_is_malicious_vf function is cleaned up and moved into ice_virtchnl.c since it is not Single Root IOV specific, and thus does not belong in ice_sriov.c I could probably have done this in fewer patches, but I split pieces out to hopefully aid in reviewing the overall sequence of changes. This does cause some additional thrash as it results in intermediate versions of the refactor, but I think its worth it for making each step easier to understand. * '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue: ice: call ice_is_malicious_vf() from ice_vc_process_vf_msg() ice: move ice_is_malicious_vf() to ice_virtchnl.c ice: print message if ice_mbx_vf_state_handler returns an error ice: pass mbxdata to ice_is_malicious_vf() ice: remove unnecessary &array[0] and just use array ice: always report VF overflowing mailbox even without PF VSI ice: declare ice_vc_process_vf_msg in ice_virtchnl.h ice: initialize mailbox snapshot earlier in PF init ice: merge ice_mbx_report_malvf with ice_mbx_vf_state_handler ice: remove ice_mbx_deinit_snapshot ice: move VF overflow message count into struct ice_mbx_vf_info ice: track malicious VFs in new ice_mbx_vf_info structure ice: convert ice_mbx_clear_malvf to void and use WARN ice: re-order ice_mbx_reset_snapshot function ==================== Link: https://lore.kernel.org/r/20230313182123.483057-1-anthony.l.nguyen@intel.comSigned-off-by:

Currently, kernel would set MSG_CTRUNC flag if msg_control buffer wasn't provided and SO_PASSCRED was set or if there was pending SCM_RIGHTS. For some reason we have no corresponding check for SO_PASSSEC. In the recvmsg(2) doc we have: MSG_CTRUNC indicates that some control data was discarded due to lack of space in the buffer for ancillary data. So, we need to set MSG_CTRUNC flag for all types of SCM. This change can break applications those don't check MSG_CTRUNC flag. Cc: "David S.

It is preferred to use typed property access functions (i.e. of_property_read_<type> functions) rather than low-level of_get_property/of_find_property functions for reading properties. As part of this, convert of_get_property/of_find_property calls to the recently added of_property_present() helper when we just want to test for presence of a property and nothing more.

Tony Nguyen says: ==================== i40e: support XDP multi-buffer Tirthendu Sarkar says: This patchset adds multi-buffer support for XDP. Tx side already has support for multi-buffer. This patchset focuses on Rx side. The last patch contains actual multi-buffer changes while the previous ones are preparatory patches. On receiving the first buffer of a packet, xdp_buff is built and its subsequent buffers are added to it as frags. While 'next_to_clean' keeps pointing to the first descriptor, the newly introduced 'next_to_process' keeps track of every descriptor for the packet. On receiving EOP buffer the XDP program is called and appropriate action is taken (building skb for XDP_PASS, reusing page for XDP_DROP, adjusting page offsets for XDP_{REDIRECT,TX}). The patchset also streamlines page offset adjustments for buffer reuse to make it easier to post process the rx_buffers after running XDP prog. With this patchset there does not seem to be any performance degradation for XDP_PASS and some improvement (~1% for XDP_TX, ~5% for XDP_DROP) when measured using xdp_rxq_info program from samples/bpf/ for 64B packets. v1: https://lore.kernel.org/netdev/20230306210822.3381942-1-anthony.l.nguyen@intel.com/ * '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue: i40e: add support for XDP multi-buffer Rx i40e: add xdp_buff to i40e_ring struct i40e: introduce next_to_process to i40e_ring i40e: use frame_sz instead of recalculating truesize for building skb i40e: Change size to truesize when using i40e_rx_buffer_flip() i40e: add pre-xdp page_count in rx_buffer i40e: change Rx buffer size for legacy-rx to support XDP multi-buffer i40e: consolidate maximum frame size calculation for vsi ==================== Link: https://lore.kernel.org/r/20230309212819.1198218-1-anthony.l.nguyen@intel.comSigned-off-by:
