[PATCH] RDMA/irdma: puda: Clear entries after allocation to ensure clean state

by Wentao Liang

The irdma_puda_send() calls the irdma_puda_get_next_send_wqe() to get entries, but does not clear the entries after the function call. This could lead to wqe data inconsistency. A proper implementation can be found in irdma_uk_send(). Add the irdma_clr_wqes() after irdma_puda_get_next_send_wqe(). Add the headfile of the irdma_clr_wqes().

[PATCH net] hv_netvsc: fix potential deadlock in netvsc_vf_setxdp()

by Saurabh Sengar

The MANA driver's probe registers netdevice via the following call chain: mana_probe() register_netdev() register_netdevice() register_netdevice() calls notifier callback for netvsc driver, holding the netdev mutex via netdev_lock_ops(). Further this netvsc notifier callback end up attempting to acquire the same lock again in dev_xdp_propagate() leading to deadlock. netvsc_netdev_event() netvsc_vf_setxdp() dev_xdp_propagate() This deadlock was not observed so far because net_shaper_ops was never set and this lock in noop in this case. Fix this by using netif_xdp_propagate instead of dev_xdp_propagate to avoid recursive locking in this path. This issue has not observed so far because net_shaper_ops was unset, making the lock path effectively a no-op. To prevent recursive locking and avoid this deadlock, replace dev_xdp_propagate() with netif_xdp_propagate(), which does not acquire the lock again. Also, clean up the unregistration path by removing unnecessary call to netvsc_vf_setxdp(), since unregister_netdevice_many_notify() already performs this cleanup via dev_xdp_uninstall.

[PATCH] wifi: wilc1000: Handle wilc_sdio_cmd52() failure in wilc_sdio_read_init()

by Wentao Liang

The wilc_sdio_read_init() calls wilc_sdio_cmd52() but does not check the return value. This could lead to execution with potentially invalid data if wilc_sdio_cmd52() fails. A proper implementation can be found in wilc_sdio_read_reg(). Add error handling for wilc_sdio_cmd52(). If wilc_sdio_cmd52() fails, log an error message via dev_err().

When this happens, if kmemleak fails to scan the new xa_head before it moves, kmemleak will see it as a leak until the xarray is scanned again. The report can be reproduced by running the xdp_bonding BPF selftest, although it doesn't appear consistently due to the bug's transience. In my testing, the following script has reliably triggered the report in under an hour on a debug kernel with kmemleak enabled, where KSELFTESTS is set to the install path for the kernel selftests: #!/bin/sh set -eu echo 1 >/sys/module/kmemleak/parameters/verbose echo scan=1 >/sys/kernel/debug/kmemleak while :; do $KSELFTESTS/bpf/test_progs -t xdp_bonding done To prevent this false positive report, mark the new xa_head in xas_shrink() as a transient leak.
