Hi,

FYI, your patch has been queued to stable release 24.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/29/26. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/a648d9669b83ab84b0fd1c955efb245430ab5e2b

Thanks.

Subject: [PATCH] net/bnxt/tf_ulp: fix HA timer spinlock leak

[ upstream commit 9f1fce2419b041e5b91836046464d15a837b9945 ]

ulp_ha_mgr_timer_cb() acquires the global ULP context spinlock via
bnxt_ulp_cntxt_entry_acquire(). When myclient_cnt is transiently 0,
the function did a bare return without calling
bnxt_ulp_cntxt_entry_release(), leaking the lock and deadlocking all
subsequent flow operations on the device.

Replace the bare return with goto cb_restart, matching every other
error path in the callback: it releases the lock and restarts the
timer. Since a zero client count is transient, restarting the timer
is the correct behavior, so the misleading "kill timer" log message
is updated accordingly.

Fixes: 1993b267dbcb ("net/bnxt: cleanup ULP parser and mapper")
