2023-10-03net: microchip: sparx5: clean up error checking in vcap_show_admin()Dan Carpenter1-1/+1
The vcap_decode_rule() never returns NULL. There is no need to check for that. This code assumes that if it did return NULL we should end abruptly and return success. It is confusing. Fix the check to just be if (IS_ERR()) instead of if (IS_ERR_OR_NULL()).

2023-09-20net: ethernet: microchip: Convert to platform remove callback returning voidUwe Kleine-König2-8/+4
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. Signed-off-by: Uwe Kleine-König <[email protected]> Signed-off-by: David S.

2023-09-17net: microchip: lan743x: add fixed phy unregister supportPavithra Sathyanarayanan1-0/+6
When operating in fixed phy mode and if there is repeated open/close phy test cases, everytime the fixed phy is registered as a new phy which leads to overrun after 32 iterations. It is solved by adding fixed_phy_unregister() in the phy_close path. In phy_close path, netdev->phydev cannot be used directly in fixed_phy_unregister() due to two reasons, - netdev->phydev is set to NULL in phy_disconnect() - fixed_phy_unregister() can be called only after phy_disconnect() So saving the netdev->phydev in local variable 'phydev' and passing it to phy_disconnect().

2023-09-15net: microchip: sparx5: Fix possible memory leak in vcap_api_encode_rule_test()Jinjie Ruan1-0/+6
Inject fault while probing kunit-example-test.ko, the duprule which is allocated in vcap_dup_rule() and the vcap enabled port which is allocated in vcap_enable() of vcap_enable_lookups in vcap_api_encode_rule_test() is not freed, and it cause the memory leaks below. Use vcap_enable_lookups() with false arg to free the vcap enabled port as other drivers do it. And use vcap_del_rule() to free the duprule. unreferenced object 0xffff677a0278bb00 (size 64): comm "kunit_try_catch", pid 388, jiffies 4294895987 (age 1101.840s) hex dump (first 32 bytes): 18 bd a5 82 00 80 ff ff 18 bd a5 82 00 80 ff ff ................ 40 fe c8 0e be c6 ff ff 00 00 00 00 00 00 00 00 @............... backtrace: [<000000007d53023a>] slab_post_alloc_hook+0xb8/0x368 [<0000000076e3f654>] __kmem_cache_alloc_node+0x174/0x290 [<0000000034d76721>] kmalloc_trace+0x40/0x164 [<00000000013380a5>] vcap_enable_lookups+0x1c8/0x70c [<00000000bbec496b>] vcap_api_encode_rule_test+0x2f8/0xb18 [<000000002c2bfb7b>] kunit_try_run_case+0x50/0xac [<00000000ff74642b>] kunit_generic_run_threadfn_adapter+0x20/0x2c [<000000004af845ca>] kthread+0x124/0x130 [<0000000038a000ca>] ret_from_fork+0x10/0x20 unreferenced object 0xffff677a027803c0 (size 192): comm "kunit_try_catch", pid 388, jiffies 4294895988 (age 1101.836s) hex dump (first 32 bytes): 00 12 7a 00 05 00 00 00 0a 00 00 00 64 00 00 00 ..z.........d... 00 00 00 00 00 00 00 00 d8 03 78 02 7a 67 ff ff ..........x.zg.. backtrace: [<000000007d53023a>] slab_post_alloc_hook+0xb8/0x368 [<0000000076e3f654>] __kmem_cache_alloc_node+0x174/0x290 [<0000000034d76721>] kmalloc_trace+0x40/0x164 [<00000000c1010131>] vcap_dup_rule+0x34/0x14c [<00000000d43c54a4>] vcap_add_rule+0x29c/0x32c [<0000000073f1c26d>] vcap_api_encode_rule_test+0x304/0xb18 [<000000002c2bfb7b>] kunit_try_run_case+0x50/0xac [<00000000ff74642b>] kunit_generic_run_threadfn_adapter+0x20/0x2c [<000000004af845ca>] kthread+0x124/0x130 [<0000000038a000ca>] ret_from_fork+0x10/0x20 Fixes: c956b9b318d9 ("net: microchip: sparx5: Adding KUNIT tests of key/action values in VCAP API") Signed-off-by: Jinjie Ruan <[email protected]> Signed-off-by: David S.

2023-08-02net: remove phy_has_hwtstamp() -> phy_mii_ioctl() decision from converted ↵Vladimir Oltean2-17/+14
drivers It is desirable that the new .ndo_hwtstamp_set() API gives more uniformity, less overhead and future flexibility w.r.t. the PHY timestamping behavior. Currently there are some drivers which allow PHY timestamping through the procedure mentioned in Documentation/networking/timestamping.rst. They don't do anything locally if phy_has_hwtstamp() is set, except for lan966x which installs PTP packet traps. Centralize that behavior in a new dev_set_hwtstamp_phylib() code function, which calls either phy_mii_ioctl() for the phylib PHY, or .ndo_hwtstamp_set() of the netdev, based on a single policy (currently simplistic: phy_has_hwtstamp()). Any driver converted to .ndo_hwtstamp_set() will automatically opt into the centralized phylib timestamping policy. Unconverted drivers still get to choose whether they let the PHY handle timestamping or not. Netdev drivers with integrated PHY drivers that don't use phylib presumably don't set dev->phydev, and those will always see HWTSTAMP_SOURCE_NETDEV requests even when converted. The timestamping policy will remain 100% up to them.

Since we already have an "enable" variable in tc_taprio_qopt_offload, refactor all drivers to check for "cmd" instead of "enable", and reject every other command except "replace" and "destroy" - to be future proof.

2023-05-23lan966x: Fix unloading/loading of the driverHoratiu Vultur1-0/+10
It was noticing that after a while when unloading/loading the driver and sending traffic through the switch, it would stop working. It would stop forwarding any traffic and the only way to get out of this was to do a power cycle of the board. The root cause seems to be that the switch core is initialized twice. Apparently initializing twice the switch core disturbs the pointers in the queue systems in the HW, so after a while it would stop sending the traffic. Unfortunetly, it is not possible to use a reset of the switch here, because the reset line is connected to multiple devices like MDIO, SGPIO, FAN, etc. So then all the devices will get reseted when the network driver will be loaded. So the fix is to check if the core is initialized already and if that is the case don't initialize it again.

But it is also possible to send back the frame without needing a xdp_frame, because it is possible to send it back using the page. And then once the frame is transmitted is possible to use directly page_pool_recycle_direct as lan966x is using page pools. This would save some CPU usage on this path, which results in higher number of transmitted frames.

From time to time, it was observed that the nanosecond part of the received timestamp, which is extracted from the IFH, it was actually bigger than 1 second. So then when actually calculating the full received timestamp, based on the nanosecond part from IFH and the second part which is read from HW, it was actually wrong. The issue seems to be inside the function lan966x_ifh_get, which extracts information from an IFH(which is an byte array) and returns the value in a u64. When extracting the timestamp value from the IFH, which starts at bit 192 and have the size of 32 bits, then if the most significant bit was set in the timestamp, then this bit was extended then the return value became 0xffffffff... . And the reason of this is because constants without any postfix are treated as signed longs and that is the reason why '1 << 31' becomes 0xffffffff80000000. This is fixed by adding the postfix 'ULL' to 1. Fixes: fd7627833ddf ("net: lan966x: Stop using packing library") Signed-off-by: Horatiu Vultur <[email protected]> Signed-off-by: David S.
