* scsi: iscsi: qla4xxx: fix double free in probeDan Carpenter2020-04-281-1/+0
| | | | | | | | | | | | | | | | | commit fee92f25777789d73e1936b91472e9c4644457c8 upstream. On this error path we call qla4xxx_mem_free() and then the caller also calls qla4xxx_free_adapter() which calls qla4xxx_mem_free(). It leads to a couple double frees: drivers/scsi/qla4xxx/ql4_os.c:8856 qla4xxx_probe_adapter() warn: 'ha->chap_dma_pool' double freed drivers/scsi/qla4xxx/ql4_os.c:8856 qla4xxx_probe_adapter() warn: 'ha->fw_ddb_dma_pool' double freed Fixes: afaf5a2d341d ("[SCSI] Initial Commit of qla4xxx") Link: https://lore.kernel.org/r/20191203094421.hw7ex7qr3j2rbsmx@kili.mountain Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Martin K.

* scsi: qla4xxx: fix double free bugPan Bian2020-02-111-3/+0
| | | | | | | | | | | | | | | commit 3fe3d2428b62822b7b030577cd612790bdd8c941 upstream. The variable init_fw_cb is released twice, resulting in a double free bug. The call to the function dma_free_coherent() before goto is removed to get rid of potential double free. Fixes: 2a49a78ed3c8 ("[SCSI] qla4xxx: added IPv6 support.")

* [SCSI] libiscsi: Reduce locking contention in fast pathShlomo Pongratz2014-03-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace the session lock with two locks, a forward lock and a backwards lock named frwd_lock and back_lock respectively. The forward lock protects resources that change while sending a request to the target, such as cmdsn, queued_cmdsn, and allocating task from the commands' pool with kfifo_out. The backward lock protects resources that change while processing a response or in error path, such as cmdsn_exp, cmdsn_max, and returning tasks to the commands' pool with kfifo_in. Under a steady state fast-path situation, that is when one or more processes/threads submit IO to an iscsi device and a single kernel upcall (e.g softirq) is dealing with processing of responses without errors, this patch eliminates the contention between the queuecommand()/request response/scsi_done() flows associated with iscsi sessions. Between the forward and the backward locks exists a strict locking hierarchy. The mutual exclusion zone protected by the forward lock can enclose the mutual exclusion zone protected by the backward lock but not vice versa. For example, in iscsi_conn_teardown or in iscsi_xmit_data when there is a failure and __iscsi_put_task is called, the backward lock is taken while the forward lock is still taken. On the other hand, if in the RX path a nop is to be sent, for example in iscsi_handle_reject or __iscsi_complete_pdu than the forward lock is released and the backward lock is taken for the duration of iscsi_send_nopout, later the backward lock is released and the forward lock is retaken. libiscsi_tcp uses two kernel fifos the r2t pool and the r2t queue. The insertion and deletion from these queues didn't corespond to the assumption taken by the new forward/backwards session locking paradigm. That is, in iscsi_tcp_clenup_task which belongs to the RX (backwards) path, r2t is taken out from r2t queue and inserted to the r2t pool. In iscsi_tcp_get_curr_r2t which belong to the TX (forward) path, r2t is also inserted to the r2t pool and another r2t is pulled from r2t queue. Only in iscsi_tcp_r2t_rsp which is called in the RX path but can requeue to the TX path, r2t is taken from the r2t pool and inserted to the r2t queue. In order to cope with this situation, two spin locks were added, pool2queue and queue2pool. The former protects extracting from the r2t pool and inserting to the r2t queue, and the later protects the extracing from the r2t queue and inserting to the r2t pool.

| | | | | | | | | | | | | | | | | | | | | | | | Issue: Driver holds rom-lock for too long during reset recovery. During adapter reset testing, it was found that the driver holds the rom-lock for too long, because of which other drivers fail to acquire the rom-lock, leading to reset failures. The primary cause is, in the bootstrap code, while holding the rom-lock, the driver checks if the peg is halted, causing a 2 second contention. Fix: When a reset recovery starts, the driver deduces the cause, and sets appropriate flags in watchdog & recover_adapter routines. This flag should be used to determine if bootstrap is invoked from probe or reset context, reducing the rom-lock footprint of the drivers.
