`strncpy` is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. NUL-padding is not required as drvinfo is memset to 0: | memset(drvinfo, 0, sizeof(struct ethtool_drvinfo)); A suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding.

strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. A suitable replacement is strscpy() [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding. bcm_enet_get_drvinfo() already uses strscpy(), let's match it's implementation: | static void bcm_enet_get_drvinfo(struct net_device *netdev, | struct ethtool_drvinfo *drvinfo) | { | strscpy(drvinfo->driver, bcm_enet_driver_name, sizeof(drvinfo->driver)); | strscpy(drvinfo->bus_info, "bcm63xx", sizeof(drvinfo->bus_info)); | } Note that now bcm_enet_get_drvinfo() and bcm_enetsw_get_drvinfo() do the exact same thing.

The driver gained a .ndo_poll_controller() at a time where the TX cleaning process was always done from NAPI which makes this unnecessary. See commit ac3d9dd0 ("netpoll: make ndo_poll_controller() optional") for more background. Signed-off-by:

We have a big change how locking is handled in cfg80211 and mac80211 which removes several locks and hopefully simplifies the locking overall. In drivers rtw89 got MCC support and smaller features to other active drivers but nothing out of ordinary. Major changes: cfg80211 - remove wdev mutex, use the wiphy mutex instead - annotate iftype_data pointer with sparse - first kunit tests, for element defrag - remove unused scan_width support mac80211 - major locking rework, remove several locks like sta_mtx, key_mtx etc. and use the wiphy mutex instead - remove unused shifted rate support - support antenna control in frame injection (requires driver support) - convert RX_DROP_UNUSABLE to more detailed reason codes rtw89 - TDMA-based multi-channel concurrency (MCC) support iwlwifi - support set_antenna() operation - support frame injection antenna control ath12k - WCN7850: enable 320 MHz channels in 6 GHz band - WCN7850: hardware rfkill support - WCN7850: enable IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS to make scan faster ath11k - add chip id board name while searching board-2.bin * tag 'wireless-next-2023-10-06' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next: (272 commits) wifi: rtlwifi: remove unreachable code in rtl92d_dm_check_edca_turbo() wifi: rtw89: debug: txpwr table supports Wi-Fi 7 chips wifi: rtw89: debug: show txpwr table according to chip gen wifi: rtw89: phy: set TX power RU limit according to chip gen wifi: rtw89: phy: set TX power limit according to chip gen wifi: rtw89: phy: set TX power offset according to chip gen wifi: rtw89: phy: set TX power by rate according to chip gen wifi: rtw89: mac: get TX power control register according to chip gen wifi: rtlwifi: use unsigned long for rtl_bssid_entry timestamp wifi: rtlwifi: fix EDCA limit set by BT coexistence wifi: rt2x00: fix MT7620 low RSSI issue wifi: rtw89: refine bandwidth 160MHz uplink OFDMA performance wifi: rtw89: refine uplink trigger based control mechanism wifi: rtw89: 8851b: update TX power tables to R34 wifi: rtw89: 8852b: update TX power tables to R35 wifi: rtw89: 8852c: update TX power tables to R67 wifi: rtw89: regd: configure Thailand in regulation type wifi: mac80211: add back SPDX identifier wifi: mac80211: fix ieee80211_drop_unencrypted_mgmt return type/value wifi: rtlwifi: cleanup few rtlxxxx_set_hw_reg() routines ... ==================== Link: https://lore.kernel.org/r/87jzrz6bvw.fsf@kernel.orgSigned-off-by:

`strncpy` is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. We expect netdev->name to be NUL-terminated based on its use with format strings and dev_info(): | dev_info(&adapter->pdev->dev, | "%s link is up %d Mbps %s\n", | netdev->name, adapter->link_speed, | adapter->link_duplex == FULL_DUPLEX ? | "full duplex" : "half duplex"); Furthermore, NUL-padding is not required as netdev is already zero-initialized through alloc_etherdev(). Considering the above, a suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding.

It should be noted that there doesn't currently exist a bug here as DRV_NAME is a small string literal which means no overread bugs are present.

Petr Machata says: ==================== mlxsw: Control the order of blocks in ACL region Amit Cohen writes: For 12 key blocks in the A-TCAM, rules are split into two records, which constitute two lookups. The two records are linked using a "large entry key ID". Due to a Spectrum-4 hardware issue, KVD entries that correspond to key blocks 0 to 5 of 12 key blocks will be placed in the same KVD pipe if they only differ in their "large entry key ID", as it is ignored. This results in a reduced scale, we can insert less than 20k filters and get an error: $ tc -b flower.batch RTNETLINK answers: Input/output error We have an error talking to the kernel To reduce the probability of this issue, we can place key blocks with high entropy in blocks 0 to 5. The idea is to place blocks that are often changed in blocks 0 to 5, for example, key blocks that match on IPv4 addresses or the LSBs of IPv6 addresses. Such placement will reduce the probability of these blocks to be same. Mark several blocks with 'high_entropy' flag and place them in blocks 0 to 5. Note that the list of the blocks is just a suggestion, I will verify it with architects. Currently, there is a one loop that chooses which blocks should be used for a given list of elements and fills the blocks - when a block is chosen, it fills it in the region. To be able to control the order of the blocks, separate between searching blocks and filling them. Several pre-changes are required. Patch set overview: Patch #1 marks several blocks with 'high_entropy' flag. Patches #2-#4 prepare the code for filling blocks at the end of the search. Patch #5 changes the loop to just choose the blocks and fill the blocks at the end. ==================== Signed-off-by: -

The previous patches prepared the code to allow separating between choosing blocks and filling blocks. Do not add blocks as part of the loop that chooses them. When all the required blocks are set in the bitmap 'chosen_blocks_bm', start filling blocks. Iterate over the bitmap twice - first add only blocks that are marked with 'high_entropy' flag. Then, fill the rest of the blocks. The idea is to place key blocks with high entropy in blocks 0 to 5. See more details in previous patches. Signed-off-by:

Currently, mlxsw_afk_picker() chooses which blocks will be used for a given list of elements, and fills the blocks during the searching - when a key block is found with most hits, it adds it and removes the elements from the count of hits. This should be changed as we want to be able to choose which blocks will be placed in blocks 0 to 5. To separate between choosing blocks and filling blocks, several pre-changes are required. Currently, the indication of whether all elements were found in the chosen blocks is by the structure 'key_info->elusage'. This structure is updated when block is filled as part of mlxsw_afk_picker_key_info_add(). A following patch will call this function only after choosing all the blocks. Add a bitmap called 'elusage_chosen' to store which elements were chosen in the chosen blocks. Change the condition in the loop to check elements that were chosen, not elements that were already filled in the blocks. Signed-off-by:

Edward Cree says: ==================== sfc: conntrack offload for tunnels This series adds support for offloading TC flower rules which require both connection tracking and tunnel decapsulation. Depending on the match keys required, the left-hand-side rule may go in either the Outer Rule table or the Action Rule table. ==================== Signed-off-by: -
Edward Cree authored
When a foreign LHS rule (TC rule from a tunnel netdev which requests conntrack lookup) matches on inner headers or enc_key_id, these matches cannot be performed by the Outer Rule table, as the keys are only available after the tunnel type has been identified (by the OR lookup) and the rest of the headers parsed accordingly. Offload such rules with an Action Rule, using the LOOKUP_CONTROL section of the AR response to specify the conntrack and/or recirculation actions, combined with an Outer Rule which performs only the usual Encap Match duties. This processing flow, as it requires two AR lookups per packet, is less performant than OR-CT-AR, so only use it where necessary. Reviewed-by:

There were a few places where no extack error message was set, or the extack was not forwarded to callees, potentially resulting in a return of -EOPNOTSUPP with no additional information. Make sure to populate the error message in these cases. In practice this does us no good as TC indirect block callbacks don't come with an extack to fill in; but maybe they will someday and when debugging it's possible to provide a fake extack and emit its message to the console.

Edward Cree authored
Normally, if a TC filter on a tunnel netdev does not match on any encap fields, we decline to offload it, as it cannot meet our requirement for a <sip,dip,dport> tuple for the encap match. However, if the rule has a nonzero chain_index, then for a packet to reach the rule, it must already have matched a LHS rule which will have included an encap match and determined the tunnel type, so in that case we can offload the right-hand-side rule. Reviewed-by:

Edward Cree authored
Allow a tunnel netdevice (such as a vxlan) to offload conntrack lookups, in much the same way as efx netdevs. To ensure this rule does not overlap with other tunnel rules on the same sip,dip,dport tuple, register a pseudo encap match of a new type (EFX_TC_EM_PSEUDO_OR), which unlike PSEUDO_MASK may only be referenced once (because an actual Outer Rule in hardware exists, although its fw_id is not recorded in the encap match entry).

Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct nfp_eth_table. Cc: Simon Horman <simon.horman@corigine.com> Cc: Jakub Kicinski <kuba@kernel.org> Cc: "David S.

Russell King says: ==================== Rework tx fault fixups This series reworks the tx-fault fixup and then improves the Nokia GPON workaround to also ignore the RX LOS signal as well. We do this by introducing a mask of hardware pin states that should be ignored, converting the tx-fault fixup to use that, and then augmenting it for RX LOS. ==================== Link: https://lore.kernel.org/r/ZRwYJXRizvkhm83M@shell.armlinux.org.ukSigned-off-by:

Improve the Nokia GPON fixup - we need to ignore not only the hardware LOS signal, but also the software implementation as well. Do this by using the new state_ignore_mask to indicate that we should ignore not only the hardware RX_LOS signal, and also clear the LOS bits in the option field. Signed-off-by:

Re-implement how we ignore the hardware TX_FAULT signal. Rather than having a separate boolean for this, use a bitmask of the hardware signals that we wish to ignore. This gives more flexibility in the future to ignore other signals such as RX_LOS. Signed-off-by:

AR7 is going to be removed from the Kernel, so remove its networking support in form of the cpmac driver. This allows us to remove the platform because this driver includes a platform specific header. Signed-off-by:
