2021-11-18octeontx2-af: debugfs: don't corrupt user memoryDan Carpenter1-7/+10
The user supplies the "count" value to say how big its read buffer is. The rvu_dbg_lmtst_map_table_display() function does not take the "count" into account but instead just copies the whole table, potentially corrupting the user's data. Introduce the "ret" variable to store how many bytes we can copy. Also I changed the type of "off" to size_t to make using min() simpler.

2021-11-10net: marvell: mvpp2: Fix wrong SerDes reconfiguration orderMarek Behún1-18/+20
Commit bfe301ebbc94 ("net: mvpp2: convert to use mac_prepare()/mac_finish()") introduced a bug wherein it leaves the MAC RESET register asserted after mac_finish(), due to wrong order of function calls. Before it was: .mac_config() mvpp22_mode_reconfigure() assert reset mvpp2_xlg_config() deassert reset Now it is: .mac_prepare() .mac_config() mvpp2_xlg_config() deassert reset .mac_finish() mvpp2_xlg_config() assert reset Obviously this is wrong. This bug is triggered when phylink tries to change the PHY interface mode from a GMAC mode (sgmii, 1000base-x, 2500base-x) to XLG mode (10gbase-r, xaui). The XLG mode does not work since reset is left asserted. Only after ifconfig down && ifconfig up is called will the XLG mode work. Move the call to mvpp22_mode_reconfigure() to .mac_prepare() implementation. Since some of the subsequent functions need to know whether the interface is being changed, we unfortunately also need to pass around the new interface mode before setting port->phy_interface.

2021-10-29net: marvell: prestera: add firmware v4.0 supportVolodymyr Mytnyk8-719/+951
Add firmware (FW) version 4.0 support for Marvell Prestera driver. Major changes have been made to new v4.0 FW ABI to add support of new features, introduce the stability of the FW ABI and ensure better forward compatibility for the future driver vesrions. Current v4.0 FW feature set support does not expect any changes to ABI, as it was defined and tested through long period of time. The ABI may be extended in case of new features, but it will not break the backward compatibility. ABI major changes done in v4.0: - L1 ABI, where MAC and PHY API configuration are split. - ACL has been split to low-level TCAM and Counters ABI to provide more HW ACL capabilities for future driver versions. To support backward support, the addition compatibility layer is required in the driver which will have two different codebase under "if FW-VER elif FW-VER else" conditions that will be removed in the future anyway, So, the idea was to break backward support and focus on more stable FW instead of supporting old version with very minimal and limited set of features/capabilities. Improve FW msg validation: * Use __le64, __le32, __le16 types in msg to/from FW to catch endian mismatch by sparse. * Use BUILD_BUG_ON for structures sent/recv to/from FW.

2021-10-28octeontx2-af: cn10k: debugfs for dumping LMTST map tableHarman Kalra1-0/+94
CN10k SoCs use atomic stores of up to 128 bytes to submit packets/instructions into co-processor cores. The enqueueing is performed using Large Memory Transaction Store (LMTST) operations. They allow for lockless enqueue operations - i.e., two different CPU cores can submit instructions to the same queue without needing to lock the queue or synchronize their accesses. This patch implements a new debugfs entry for dumping LMTST map table present on CN10K, as this might be very useful to debug any issue in case of shared LMTST region among multiple pci functions.

2021-10-28octeontx2-af: Display all enabled PF VF rsrc_alloc entries.Rakesh Babu1-32/+106
Currently, we are using a fixed buffer size of length 2048 to display rsrc_alloc output. As a result a maximum of 2048 characters of rsrc_alloc output is displayed, which may lead sometimes to display only partial output. This patch fixes this dependency on max limit of buffer size and displays all PF VF entries. Each column of the debugfs entry "rsrc_alloc" uses a fixed width of 12 characters to print the list of LFs of each block for a PF/VF. If the length of list of LFs of a block exceeds this fixed width then the list gets truncated and displays only a part of the list. This patch fixes this by using the maximum possible length of list of LFs among all blocks of all PFs and VFs entries as the width size.

2021-10-14ethernet: constify references to netdev->dev_addr in driversJakub Kicinski3-6/+6
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.

This patch separates the logic of configuring hardware maximum transmit frame size and receive frame size. This simplifies the logic to calculate receive buffer size and using cqe descriptor of different size. Also additional size of skb_shared_info structure is allocated for each receive buffer pointer given to hardware which is not necessary. Hence change the size calculation to remove the size of skb_shared_info. Add a check for array out of bounds while adding fragments to the network stack.
