This makes\nthe full-pass termination independent of the transport state while\npreserving the existing fallback selection semantics.\n\nAlso restore the NULL guard around the retran_path assignment. In the\nall-UNCONFIRMED case there is no eligible replacement transport, and\ninstalling NULL would leave later retransmit-path users and the debug\nprint with a NULL path.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/173610fff55022a5ad1579fbcc7faa97467b58b7","tags":[]},{"url":"https://git.kernel.org/stable/c/3fe624c3843694ab096fdb198526ba0c659febbe","tags":[]},{"url":"https://git.kernel.org/stable/c/43410c1f2db53516e95ddd7e5b4b02f495b78121","tags":[]},{"url":"https://git.kernel.org/stable/c/83b1a7f9e718828ef364a7b004254ebb2d0035fe","tags":[]},{"url":"https://git.kernel.org/stable/c/c9338057df1025f578fe7d0ff08bada87b8b838d","tags":[]},{"url":"https://git.kernel.org/stable/c/d2c31b837406395e576afeb25958c98e9938f3f6","tags":[]},{"url":"https://git.kernel.org/stable/c/d893a7cc1cb41dd510f338bb2bfd8f29b14eaf49","tags":[]},{"url":"https://git.kernel.org/stable/c/ddc34cc0834c873871e88b055ee6a260676efe97","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
