2021-03-30scsi: qla2xxx: Fix use after free in bsgQuinn Tran1-1/+2
On bsg command completion, bsg_job_done() was called while qla driver continued to access the bsg_job buffer. bsg_job_done() would free up resources that ended up being reused by other task while the driver continued to access the buffers.

2021-03-30scsi: iscsi: Fix race condition between login and sync threadGulam Mohamed2-1/+14
A kernel panic was observed due to a timing issue between the sync thread and the initiator processing a login response from the target. The session reopen can be invoked both from the session sync thread when iscsid restarts and from iscsid through the error handler. Before the initiator receives the response to a login, another reopen request can be sent from the error handler/sync session. When the initial login response is subsequently processed, the connection has been closed and the socket has been released. To fix this a new connection state, ISCSI_CONN_BOUND, is added: - Set the connection state value to ISCSI_CONN_DOWN upon iscsi_if_ep_disconnect() and iscsi_if_stop_conn() - Set the connection state to the newly created value ISCSI_CONN_BOUND after bind connection (transport->bind_conn()) - In iscsi_set_param(), return -ENOTCONN if the connection state is not either ISCSI_CONN_BOUND or ISCSI_CONN_UP Link: https://lore.kernel.org/r/20210325093248.284678-1-gulam.mohamed@oracle.com Reviewed-by: Mike Christie <michael.christie@oracle.com> Signed-off-by: Gulam Mohamed <gulam.mohamed@oracle.com> Signed-off-by: Martin K.

If pscsi_map_sg() fails, make sure to drop references to already allocated bios.

2021-03-25scsi: target: pscsi: Avoid OOM in pscsi_map_sg()Martin Wilck1-1/+0
pscsi_map_sg() uses the variable nr_pages as a hint for bio_kmalloc() how many vector elements to allocate. If nr_pages is < BIO_MAX_PAGES, it will be reset to 0 after successful allocation of the bio. If bio_add_pc_page() fails later for whatever reason, pscsi_map_sg() tries to allocate another bio, passing nr_vecs = 0. This causes bio_add_pc_page() to fail immediately in the next call. pci_map_sg() continues to allocate zero-length bios until memory is exhausted and the kernel crashes with OOM. This can be easily observed by exporting a SATA DVD drive via pscsi. The target crashes as soon as the client tries to access the DVD LUN. In the case I analyzed, bio_add_pc_page() would fail because the DVD device's max_sectors_kb (128) was exceeded. Avoid this by simply not resetting nr_pages to 0 after allocating the bio. This way, the client receives an I/O error when it tries to send requests exceeding the devices max_sectors_kb, and eventually gets it right. The client must still limit max_sectors_kb e.g. by an udev rule if (like in my case) the driver doesn't report valid block limits, otherwise it encounters I/O errors.

2021-03-25scsi: bnx2i: Make bnx2i_process_iscsi_error() simpler and more robustRasmus Villemoes1-44/+41
Instead of strcpy'ing into a stack buffer, just let additional_notice point to a string literal living in .rodata. This is better in a few ways: - Smaller .text - instead of gcc compiling the strcpys as a bunch of immediate stores (effectively encoding the string literal in the instruction stream), we only pay the price of storing the literal in .rodata. - Faster, because there's no string copying. - Smaller stack usage (with my compiler, 72 bytes instead of 176 for the sole caller, bnx2i_indicate_kcqe) Moreover, it's currently possible for additional_notice[] to get used uninitialized, so some random stack garbage would be passed to printk() - in the worst case without any '\0' anywhere in those 64 bytes. That could be fixed by initializing additional_notice[0], but the same is achieved here by initializing the new pointer variable to "". Also give the message pointer a similar treatment - there's no point making temporary copies on the stack of those two strings.

2021-03-25scsi: Revert "qla2xxx: Make sure that aborted commands are freed"Bart Van Assche2-12/+5
Calling vha->hw->tgt.tgt_ops->free_cmd() from qlt_xmit_response() is wrong since the command for which a response is sent must remain valid until the SCSI target core calls .release_cmd(). It has been observed that the following scenario triggers a kernel crash: - qlt_xmit_response() calls qlt_check_reserve_free_req() - qlt_check_reserve_free_req() returns -EAGAIN - qlt_xmit_response() calls vha->hw->tgt.tgt_ops->free_cmd(cmd) - transport_handle_queue_full() tries to retransmit the response Fix this crash by reverting the patch that introduced it.

2021-03-25scsi: ibmvfc: Make ibmvfc_wait_for_ops() MQ awareTyrel Datwyler1-17/+34
During MQ enablement of the ibmvfc driver ibmvfc_wait_for_ops() was missed. This function is responsible for waiting on commands to complete that match a certain criteria such as LUN or cancel key. The implementation as is only scans the CRQ for events ignoring any sub-queues and as a result will exit successfully without doing anything when operating in MQ channelized mode. Check the MQ and channel use flags to determine which queues are applicable, and scan each queue accordingly. Note in MQ mode SCSI commands are only issued down sub-queues and the CRQ is only used for driver specific management commands. As such the CRQ events are ignored when operating in MQ mode with channels.

2021-03-25scsi: ibmvfc: Fix potential race in ibmvfc_wait_for_ops()Tyrel Datwyler1-9/+33
For various EH activities the ibmvfc driver uses ibmvfc_wait_for_ops() to wait for the completion of commands that match a given criteria be it cancel key, or specific LUN. With recent changes commands are completed outside the lock in bulk by removing them from the sent list and adding them to a private completion list. This introduces a potential race in ibmvfc_wait_for_ops() since the criteria for a command to be outstanding is no longer simply being on the sent list, but instead not being on the free list. Avoid this race by scanning the entire command event pool and checking that any matching command that ibmvfc needs to wait on is not already on the free list.
