2018-08-02scsi: fcoe: fix use-after-free in fcoe_ctlr_els_sendJohannes Thumshirn
KASAN reports a use-after-free in fcoe_ctlr_els_send() when we're sending a LOGO and have FIP debugging enabled. This is because we're first freeing the skb and then printing the frame's DID. But the DID is a member of the FC frame header which in turn is the skb's payload. Exchange the debug print and kfree_skb() calls so we're not touching the freed data.

2018-07-12scsi: libiscsi: fix possible NULL pointer dereference in case of TMFVarun Prakash
In iscsi_check_tmf_restrictions() task->hdr is dereferenced to print the opcode, it is possible that task->hdr is NULL. There are two cases based on opcode argument: 1. ISCSI_OP_SCSI_CMD - In this case alloc_pdu() is called after iscsi_check_tmf_restrictions() iscsi_prep_scsi_cmd_pdu() -> iscsi_check_tmf_restrictions() -> alloc_pdu(). Transport drivers allocate memory for iSCSI hdr in alloc_pdu() and assign it to task->hdr. In case of TMF task->hdr will be NULL resulting in NULL pointer dereference. 2. ISCSI_OP_SCSI_DATA_OUT - In this case transport driver can free the memory for iSCSI hdr after transmitting the pdu so task->hdr can be NULL or invalid. This patch fixes this issue by removing task->hdr->opcode from the printk statement. Signed-off-by: Varun Prakash <varun@chelsio.com> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>

2018-06-26scsi: sg: mitigate read/write abuseJann Horn
As Al Viro noted in commit 128394eff343 ("sg_write()/bsg_write() is not fit to be called under KERNEL_DS"), sg improperly accesses userspace memory outside the provided buffer, permitting kernel memory corruption via splice(). But it doesn't just do it on ->write(), also on ->read(). As a band-aid, make sure that the ->read() and ->write() handlers can not be called in weird contexts (kernel context or credentials different from file opener), like for ib_safe_file_access(). If someone needs to use these interfaces from different security contexts, a new interface should be written that goes through the ->ioctl() handler. I've mostly copypasted ib_safe_file_access() over as sg_safe_file_access() because I couldn't find a good common header - please tell me if you know a better way.

2018-06-26scsi: aacraid: Fix PD performance regression over incorrect qd being setRaghava Aditya Renukunta
The driver fails to set the correct queue depth for native devices, due to failing to set the device type prior to calling aac_set_safw_target_qd(). This results in slave configure setting the queue depth to 1. This causes around 30% performance degradation. Fixed by setting the dev type before trying to set queue depth.

According to Maged: Yes it fixes the "Storage Spaces Persistent Reservation" test in the Windows 2016 Server Failover Cluster validation suites when having many connections that result in more than 8 registrations.

2018-06-18scsi: scsi_debug: Fix memory leak on module unloadLuis Henriques
Since commit 80c49563e250 ("scsi: scsi_debug: implement IMMED bit") there are long delays in F_SYNC_DELAY and F_SSU_DELAY. This can cause a memory leak in schedule_resp(), which can be invoked while unloading the scsi_debug module: free_all_queued() had already freed all sd_dp and schedule_resp will alloc a new one, which will never get freed.

2018-06-18scsi: target: tcmu: add read length supportbstroesser@ts.fujitsu.com
Generally target core and TCMUser seem to work fine for tape devices and media changers. But there is at least one situation where TCMUser is not able to support sequential access device emulation correctly. The situation is when an initiator sends a SCSI READ CDB with a length that is greater than the length of the tape block to read. We can distinguish two subcases: A) The initiator sent the READ CDB with the SILI bit being set. In this case the sequential access device has to transfer the data from the tape block (only the length of the tape block) and transmit a good status. The current interface between TCMUser and the userspace does not support reduction of the read data size by the userspace program. The patch below fixes this subcase by allowing the userspace program to specify a reduced data size in read direction. B) The initiator sent the READ CDB with the SILI bit not being set. In this case the sequential access device has to transfer the data from the tape block as in A), but additionally has to transmit CHECK CONDITION with the ILI bit set and NO SENSE in the sensebytes. The information field in the sensebytes must contain the residual count. With the below patch a user space program can specify the real read data length and appropriate sensebytes. TCMUser then uses the se_cmd flag SCF_TREAT_READ_AS_NORMAL, to force target core to transmit the real data size and the sensebytes. Note: the flag SCF_TREAT_READ_AS_NORMAL is introduced by Lee Duncan's patch "[PATCH v4] target: transport should handle st FM/EOM/ILI reads" from Tue, 15 May 2018 18:25:24 -0700.

2018-06-15kernel-parameters.txt: fix pointers to sound parametersMauro Carvalho Chehab
The alsa parameters file was renamed to alsa-configuration.rst. With regards to OSS, it got retired as a hole by at changeset 727dede0ba8a ("sound: Retire OSS"). So, it doesn't make sense to keep mentioning it at kernel-parameters.txt.
