      "title": "net/rds: No shortcut out of RDS_CONN_ERROR",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/rds: No shortcut out of RDS_CONN_ERROR\n\nRDS connections carry a state \"rds_conn_path::cp_state\"\nand transitions from one state to another and are conditional\nupon an expected state: \"rds_conn_path_transition.\"\n\nThere is one exception to this conditionality, which is\n\"RDS_CONN_ERROR\" that can be enforced by \"rds_conn_path_drop\"\nregardless of what state the condition is currently in.\n\nBut as soon as a connection enters state \"RDS_CONN_ERROR\",\nthe connection handling code expects it to go through the\nshutdown-path.\n\nThe RDS/TCP multipath changes added a shortcut out of\n\"RDS_CONN_ERROR\" straight back to \"RDS_CONN_CONNECTING\"\nvia \"rds_tcp_accept_one_path\" (e.g. after \"rds_tcp_state_change\").\n\nA subsequent \"rds_tcp_reset_callbacks\" can then transition\nthe state to \"RDS_CONN_RESETTING\" with a shutdown-worker queued.\n\nThat'll trip up \"rds_conn_init_shutdown\", which was\nnever adjusted to handle \"RDS_CONN_RESETTING\" and subsequently\ndrops the connection with the dreaded \"DR_INV_CONN_STATE\",\nwhich leaves \"RDS_SHUTDOWN_WORK_QUEUED\" on forever.\n\nSo we do two things here:\n\na) Don't shortcut \"RDS_CONN_ERROR\", but take the longer\n   path through the shutdown code.\n\nb) Add \"RDS_CONN_RESETTING\" to the expected states in\n  \"rds_conn_init_shutdown\" so that we won't error out\n  and get stuck, if we ever hit weird state transitions\n  like this again.\"",
