* ibcore: Fix sysfs registration error flowHans Petter Selasky2022-06-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel commit cited below restructured ib device management so that the device kobject is initialized in ib_alloc_device. As part of the restructuring, the kobject is now initialized in procedure ib_alloc_device, and is later added to the device hierarchy in the ib_register_device call stack, in procedure ib_device_register_sysfs (which calls device_add). However, in the ib_device_register_sysfs error flow, if an error occurs following the call to device_add, the cleanup procedure device_unregister is called. This call results in the device object being deleted -- which results in various use-after-free crashes. The correct cleanup call is device_del -- which undoes device_add without deleting the device object. The device object will then (correctly) be deleted in the ib_register_device caller's error cleanup flow, when the caller invokes ib_dealloc_device.

* ibcore: Protect against concurrent access to hardware stats.Hans Petter Selasky2021-07-121-6/+28
| | | | | | | | | | | | | | Currently access to hardware stats buffer isn't protected, this can result in multiple writes and reads at the same time to the same memory location. This can lead to providing an incorrect value to the user. Add a mutex to protect against it.

* ibcore: Do not expose unsupported counters.Hans Petter Selasky2021-07-121-7/+12
| | | | | | | | | | | | | | If the provider driver (such as rdma_rxe) doesn't support PMA counters, avoid exposing its directory similar to optional hw_counters directory. If core fails to read the PMA counter, return an error so that user can retry later if needed.

* ibcore: Fix unable to change lifespan entry for hw_counters.Hans Petter Selasky2021-07-121-1/+15
| | | | | | | | | | | | | | | | | | | | | This patch fixes the case where 'lifespan' entry of the hw_counters is not writable. Currently write callback is not exposed for for the hw_counters sysfs operation. Due to this, modifying lifespan value results into permission denied error in below example. echo 10 > /sys/class/infiniband/mlx5_0/ports/1/hw_counters/lifespan -bash: /sys/class/infiniband/mlx5_0/ports/1/hw_counters/lifespan: Permission denied This patch adds the hook to modify any attribute which implements store() operation.

* ibcore: Move debug counters to be under relevant IB deviceHans Petter Selasky2021-07-121-0/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sysfs layout is created by CM incorrectly presented RDMA devices with InfiniBand link layer. Layout of such devices represents device tree of connections. By moving CM statistics to be under relevant port of IB device, we will fix the following issues: * Symlink name - It used device name instead of specific identifier. * Target location - It was supposed to point to PCI-ID/infiniband_cm/ instead of PCI-ID/infiniband/ * Target name - It created extra device file under already existing device folder, e.g. mlx5_0/mlx5_0 * Crash during boot with RDMA persistent naming patches. sysfs: cannot create duplicate filename '/class/infiniband_cm/mlx5_0' CPU: 29 PID: 433 Comm: modprobe Not tainted 5.0.0-rc5+ #178 Call Trace: dump_stack+0xcc/0x180 sysfs_warn_dup.cold.3+0x17/0x2d sysfs_do_create_link_sd.isra.2+0xd0/0xf0 device_add+0x7cb/0x1450 device_create_groups_vargs+0x1ae/0x220 device_create+0x93/0xc0 cm_add_one+0x38f/0xf60 [ib_cm] add_client_context+0x167/0x210 [ib_core] enable_device_and_get+0x230/0x3f0 [ib_core] ib_register_device+0x823/0xbf0 [ib_core] __mlx5_ib_add+0x45/0x150 [mlx5_ib] mlx5_ib_add+0x1b3/0x5e0 [mlx5_ib] mlx5_add_device+0x130/0x3a0 [mlx5_core] mlx5_register_interface+0x1a9/0x270 [mlx5_core] do_one_initcall+0x14f/0x5de do_init_module+0x247/0x7c0 load_module+0x4c2f/0x60d0 entry_SYSCALL_64_after_hwframe+0x49/0xbe After this change: [leonro@server ~]$ ls -al /sys/class/infiniband/ibp0s12f0/ports/1/ drwxr-xr-x 2 root root 0 Mar 11 11:17 cm_rx_duplicates drwxr-xr-x 2 root root 0 Mar 11 11:17 cm_rx_msgs drwxr-xr-x 2 root root 0 Mar 11 11:17 cm_tx_msgs drwxr-xr-x 2 root root 0 Mar 11 11:17 cm_tx_retries Linux commit: c87e65cfb97c7f325132a68288ed76ba7bdcd2c6 MFC after: 1 week Reviewed by: kib Sponsored by: Mellanox Technologies // NVIDIA Networking
