2023-09-20net: ethernet: broadcom: Convert to platform remove callback returning voidUwe Kleine-König1-4/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Trivially convert these drivers from always returning zero in the remove callback to the void returning variant.

2021-12-16net: systemport: Add global locking for descriptor lifecycleFlorian Fainelli1-1/+4
The descriptor list is a shared resource across all of the transmit queues, and the locking mechanism used today only protects concurrency across a given transmit queue between the transmit and reclaiming. This creates an opportunity for the SYSTEMPORT hardware to work on corrupted descriptors if we have multiple producers at once which is the case when using multiple transmit queues. This was particularly noticeable when using multiple flows/transmit queues and it showed up in interesting ways in that UDP packets would get a correct UDP header checksum being calculated over an incorrect packet length. Similarly TCP packets would get an equally correct checksum computed by the hardware over an incorrect packet length. The SYSTEMPORT hardware maintains an internal descriptor list that it re-arranges when the driver produces a new descriptor anytime it writes to the WRITE_PORT_{HI,LO} registers, there is however some delay in the hardware to re-organize its descriptors and it is possible that concurrent TX queues eventually break this internal allocation scheme to the point where the length/status part of the descriptor gets used for an incorrect data buffer. The fix is to impose a global serialization for all TX queues in the short section where we are writing to the WRITE_PORT_{HI,LO} registers which solves the corruption even with multiple concurrent TX queues being used.

2021-10-14ethernet: constify references to netdev->dev_addr in driversJakub Kicinski1-1/+1
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.

2021-04-13of: net: pass the dst buffer to of_get_mac_address()Michael Walle1-5/+2
of_get_mac_address() returns a "const void*" pointer to a MAC address. Lately, support to fetch the MAC address by an NVMEM provider was added. But this will only work with platform devices. It will not work with PCI devices (e.g. of an integrated root complex) and esp. not with DSA ports. There is an of_* variant of the nvmem binding which works without devices. The returned data of a nvmem_cell_read() has to be freed after use. On the other hand the return of_get_mac_address() points to some static data without a lifetime. The trick for now, was to allocate a device resource managed buffer which is then returned. This will only work if we have an actual device. Change it, so that the caller of of_get_mac_address() has to supply a buffer where the MAC address is written to. Unfortunately, this will touch all drivers which use the of_get_mac_address(). Usually the code looks like: const char *addr; addr = of_get_mac_address(np); if (!IS_ERR(addr)) ether_addr_copy(ndev->dev_addr, addr); This can then be simply rewritten as: of_get_mac_address(np, ndev->dev_addr); Sometimes is_valid_ether_addr() is used to test the MAC address. of_get_mac_address() already makes sure, it just returns a valid MAC address. Thus we can just test its return code. But we have to be careful if there are still other sources for the MAC address before the of_get_mac_address(). In this case we have to keep the is_valid_ether_addr() call. The following coccinelle patch was used to convert common cases to the new style. Afterwards, I've manually gone over the drivers and fixed the return code variable: either used a new one or if one was already available use that. Mansour Moufid, thanks for that coccinelle patch! <spml> @a@ identifier x; expression y, z; @@ - x = of_get_mac_address(y); + x = of_get_mac_address(y, z); <... - ether_addr_copy(z, x); ...> @@ identifier a.x; @@ - if (<+... x ...+>) {} @@ identifier a.x; @@ if (<+... x ...+>) { ... } - else {} @@ identifier a.x; expression e; @@ - if (<+... x ...+>@e) - {} - else + if (!(e)) {...} @@ expression x, y, z; @@ - x = of_get_mac_address(y, z); + of_get_mac_address(y, z); ... when != x </spml> All drivers, except drivers/net/ethernet/aeroflex/greth.c, were compile-time tested.

2021-01-07net: systemport: use standard netdevice notifier to detect DSA presenceVladimir Oltean1-45/+36
The SYSTEMPORT driver maps each port of the embedded Broadcom DSA switch port to a certain queue of the master Ethernet controller. For that it currently uses a dedicated notifier infrastructure which was added in commit 60724d4bae14 ("net: dsa: Add support for DSA specific notifiers"). However, since commit 2f1e8ea726e9 ("net: dsa: link interfaces with the DSA master to get rid of lockdep warnings"), DSA is actually an upper of the Broadcom SYSTEMPORT as far as the netdevice adjacency lists are concerned. So naturally, the plain NETDEV_CHANGEUPPER net device notifiers are emitted. It looks like there is enough API exposed by DSA to the outside world already to make the call_dsa_notifiers API redundant. So let's convert its only user to plain netdev notifiers.

Therefore, an allocation failure of Rx SKBs is relatively benign. However, the output of the warning message occurs with a high scheduling priority that can cause excessive jitter/latency for other high priority processing.

2020-02-06net: systemport: Avoid RBUF stuck in Wake-on-LAN modeFlorian Fainelli1-0/+3
After a number of suspend and resume cycles, it is possible for the RBUF to be stuck in Wake-on-LAN mode, despite the MPD enable bit being cleared which instructed the RBUF to exit that mode. Avoid creating that problematic condition by clearing the RX_EN and TX_EN bits in the UniMAC prior to disable the Magic Packet Detector logic which is guaranteed to make the RBUF exit Wake-on-LAN mode.

2020-01-17net: systemport: Fixed queue mapping in internal ring mapFlorian Fainelli1-3/+4
We would not be transmitting using the correct SYSTEMPORT transmit queue during ndo_select_queue() which looks up the internal TX ring map because while establishing the mapping we would be off by 4, so for instance, when we populate switch port mappings we would be doing: switch port 0, queue 0 -> ring index #0 switch port 0, queue 1 -> ring index #1 ... switch port 0, queue 3 -> ring index #3 switch port 1, queue 0 -> ring index #8 (4 + 4 * 1) ... instead of using ring index #4. This would cause our ndo_select_queue() to use the fallback queue mechanism which would pick up an incorrect ring for that switch port. Fix this by using the correct switch queue number instead of SYSTEMPORT queue number.

This allows incrementing the correct timeout statistic without any mess. Down the road, devices can learn to reset just the specific queue.

2019-11-04net: of_get_phy_mode: Change API to solve int/unit warningsAndrew Lunn1-2/+2
Before this change of_get_phy_mode() returned an enum, phy_interface_t. On error, -ENODEV etc, is returned. If the result of the function is stored in a variable of type phy_interface_t, and the compiler has decided to represent this as an unsigned int, comparision with -ENODEV etc, is a signed vs unsigned comparision. Fix this problem by changing the API. Make the function return an error, or 0 on success, and pass a pointer, of type phy_interface_t, where the phy mode should be stored. v2: Return with *interface set to PHY_INTERFACE_MODE_NA on error. Add error checks to all users of of_get_phy_mode() Fixup a few reverse christmas tree errors Fixup a few slightly malformed reverse christmas trees v3: Fix 0-day reported errors.

While using net_dim, a dim_sample was used without ever initializing the comps value. Added use of DIV_ROUND_DOWN_ULL() to prevent potential overflow, it should not be a problem to save the final result in an int because after the division by epms the value should not be larger than a few thousand.

Saeed Mamameed says: ==================== Generic DIM From: Tal Gilboa and Yamin Fridman Implement net DIM over a generic DIM library, add RDMA DIM dim.h lib exposes an implementation of the DIM algorithm for dynamically-tuned interrupt moderation for networking interfaces. We want a similar functionality for other protocols, which might need to optimize interrupts differently. Main motivation here is DIM for NVMf storage protocol. Current DIM implementation prioritizes reducing interrupt overhead over latency. Also, in order to reduce DIM's own overhead, the algorithm might take some time to identify it needs to change profiles. While this is acceptable for networking, it might not work well on other scenarios. Here we propose a new structure to DIM. The idea is to allow a slightly modified functionality without the risk of breaking Net DIM behavior for netdev. We verified there are no degradations in current DIM behavior with the modified solution. Suggested solution: - Common logic is implemented in lib/dim/dim.c - Net DIM (existing) logic is implemented in lib/dim/net_dim.c, which uses the common logic in dim.c - Any new DIM logic will be implemented in "lib/dim/new_dim.c". This new implementation will expose modified versions of profiles, dim_step() and dim_decision(). - DIM API is declared in include/linux/dim.h for all implementations. Pros for this solution are: - Zero impact on existing net_dim implementation and usage - Relatively more code reuse (compared to two separate solutions) - Increased extensibility ==================== Signed-off-by: David S.
