[PATCH v2 1/2] Revert "drivers: core: synchronize really_probe() and dev_uevent()"

by Dmitry Torokhov

This reverts commit c0a40097f0bc81deafc15f9195d1fb54595cd6d0. Probing a device can take arbitrary long time. In the field we observed that, for example, probing a bad micro-SD cards in an external USB card reader (or maybe cards were good but cables were flaky) sometimes takes longer than 2 minutes due to multiple retries at various levels of the stack. We can not block uevent_show() method for that long because udev is reading that attribute very often and that blocks udev and interferes with booting of the system. The change that introduced locking was concerned with dev_uevent() racing with unbinding the driver. However we can handle it without locking (which will be done in subsequent patch). There was also claim that synchronization with probe() is needed to properly load USB drivers, however this is a red herring: the change adding the lock was introduced in May of last year and USB loading and probing worked properly for many years before that. Revert the harmful locking.

[PATCH] qlcnic: fix a memory leak in __qlcnic_pci_sriov_enable()

by Haoxiang Li

Add qlcnic_sriov_free_vlans() to free the memory allocated by qlcnic_sriov_alloc_vlans() if qlcnic_sriov_alloc_vlans() fails.

Please apply f24f669d03f8 ("x86/mm: Don't disable PCID when INVLPG has been fixed by microcode")

by Thomas Voegtle

Hi, please apply f24f669d03f8 for 6.12.y. It is already in 6.13.y. Backports of that patch would be needed for 6.6.y down to 5.4.y as it doesn't apply. But I don't know how to backport that fix but I can test anything. Thomas

[PATCH net v2] net/mlx5: handle errors in mlx5_chains_create_table()

by Wentao Liang

In mlx5_chains_create_table(), the return value of mlx5_get_fdb_sub_ns() and mlx5_get_flow_namespace() must be checked to prevent NULL pointer dereferences. If either function fails, the function should log error message with mlx5_core_warn() and return error pointer. [v1]->[v2]: Add Fixes tag. Target patch to net.

[PATCH] RDMA/mlx5: Prevent UB from shifting negative signed value

by Qasim Ijaz

In function create_ib_ah() the following line attempts to left shift the return value of mlx5r_ib_rate() by 4 and store it in the stat_rate_sl member of av: ah->av.stat_rate_sl = (mlx5r_ib_rate(dev, rdma_ah_get_static_rate(ah_attr)) << 4); However the code overlooks the fact that mlx5r_ib_rate() may return -EINVAL if the rate passed to it is less than IB_RATE_2_5_GBPS or greater than IB_RATE_800_GBPS. Because of this, the code may invoke undefined behaviour when shifting a signed negative value when doing "-EINVAL << 4". To fix this check for errors before assigning stat_rate_sl and propagate any error value to the callers.
