2023-10-02net/mlx5: Implement alias object allow and create functionsPatrisious Haddad
Add functions which allow one vhca to access another vhca object, and functions that creates an alias object or destroys it. Together they can be used to create cross vhca flow table that is able jump from the steering domain that is managed by one vport, to the steering domain on a different vport.

This includes retrieving the necessary device information and the IPsec database, which helps determine if IPsec is configured or not.

2023-10-02net/mlx5: Register mlx5e priv to devcom in MPV modePatrisious Haddad
If the device is in MPV mode, the ethernet driver would now register to events from IB driver about core devices affiliation or de-affiliation. Use the key provided in said event to connect each mlx5e priv instance to it's master counterpart, this way the ethernet driver is now aware of who is his master core device and even more, such as knowing if partner device has IPsec configured or not.

Fix by passing the specific notifier list pointer to tegra_vi_graph_find_entity() instead of the channel, so each caller can search in whatever list is correct.

2023-10-02sky2: Make sure there is at least one frag_addr availableKees Cook
In the pathological case of building sky2 with 16k PAGE_SIZE, the frag_addr[] array would never be used, so the original code was correct that size should be 0. But the compiler now gets upset with 0 size arrays in places where it hasn't eliminated the code that might access such an array (it can't figure out that in this case an rx skb with fragments would never be created). To keep the compiler happy, make sure there is at least 1 frag_addr in struct rx_ring_info: In file included from include/linux/skbuff.h:28, from include/net/net_namespace.h:43, from include/linux/netdevice.h:38, from drivers/net/ethernet/marvell/sky2.c:18: drivers/net/ethernet/marvell/sky2.c: In function 'sky2_rx_unmap_skb': include/linux/dma-mapping.h:416:36: warning: array subscript i is outside array bounds of 'dma_addr_t[0]' {aka 'long long unsigned int[]'} [-Warray-bounds=] 416 | #define dma_unmap_page(d, a, s, r) dma_unmap_page_attrs(d, a, s, r, 0) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/net/ethernet/marvell/sky2.c:1257:17: note: in expansion of macro 'dma_unmap_page' 1257 | dma_unmap_page(&pdev->dev, re->frag_addr[i], | ^~~~~~~~~~~~~~ In file included from drivers/net/ethernet/marvell/sky2.c:41: drivers/net/ethernet/marvell/sky2.h:2198:25: note: while referencing 'frag_addr' 2198 | dma_addr_t frag_addr[ETH_JUMBO_MTU >> PAGE_SHIFT]; | ^~~~~~~~~ With CONFIG_PAGE_SIZE_16KB=y, PAGE_SHIFT == 14, so: #define ETH_JUMBO_MTU 9000 causes "ETH_JUMBO_MTU >> PAGE_SHIFT" to be 0.

2023-10-02net: dsa: mv88e6xxx: Avoid EEPROM timeout when EEPROM is absentFabio Estevam
Since commit 23d775f12dcd ("net: dsa: mv88e6xxx: Wait for EEPROM done before HW reset") the following error is seen on a imx8mn board with a 88E6320 switch: mv88e6085 30be0000.ethernet-1:00: Timeout waiting for EEPROM done This board does not have an EEPROM attached to the switch though. This problem is well explained by Andrew Lunn: "If there is an EEPROM, and the EEPROM contains a lot of data, it could be that when we perform a hardware reset towards the end of probe, it interrupts an I2C bus transaction, leaving the I2C bus in a bad state, and future reads of the EEPROM do not work. The work around for this was to poll the EEInt status and wait for it to go true before performing the hardware reset. However, we have discovered that for some boards which do not have an EEPROM, EEInt never indicates complete. As a result, mv88e6xxx_g1_wait_eeprom_done() spins for a second and then prints a warning. We probably need a different solution than calling mv88e6xxx_g1_wait_eeprom_done(). The datasheet for 6352 documents the EEPROM Command register: bit 15 is: EEPROM Unit Busy. This bit must be set to a one to start an EEPROM operation (see EEOp below). Only one EEPROM operation can be executing at one time so this bit must be zero before setting it to a one. When the requested EEPROM operation completes this bit will automatically be cleared to a zero. The transition of this bit from a one to a zero can be used to generate an interrupt (the EEInt in Global 1, offset 0x00). and more interesting is bit 11: Register Loader Running. This bit is set to one whenever the register loader is busy executing instructions contained in the EEPROM." Change to using mv88e6xxx_g2_eeprom_wait() to fix the timeout error when the EEPROM chip is not present.

Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions).

debugfs_create_dir() returns ERR_PTR and never return NULL. As Russell suggested, this patch removes the error checking for debugfs_create_dir(). This is because the DebugFS kernel API is developed in a way that the caller can safely ignore the errors that occur during the creation of DebugFS nodes. The debugfs APIs have a IS_ERR() judge in start_creating() which can handle it gracefully. So these checks are unnecessary.
