2016-08-30scsi: megaraid_sas: Fix the search of first memory barChristophe JAILLET1-1/+1
The 2nd parameter of 'find_first_bit' is the number of bits to search. In this case, we are passing 'sizeof(unsigned long)' which is likely to be 4. It is likely that the number of bits in a long was expected here, so use BITS_PER_LONG instead.

2016-08-30scsi: sg: Avoid overflow when USER_HZ > HZPaul Burton1-2/+3
Calculating the maximum timeout that a user can set via the SG_SET_TIMEOUT ioctl involves multiplying INT_MAX by USER_HZ/HZ. If USER_HZ is larger than HZ then this results in an overflow when performed as a 32 bit integer calculation, resulting in compiler warnings such as the following: drivers/scsi/sg.c: In function 'sg_ioctl': drivers/scsi/sg.c:91:67: warning: integer overflow in expression [-Woverflow] #define MULDIV(X,MUL,DIV) ((((X % DIV) * MUL) / DIV) + ((X / DIV) * MUL)) ^ drivers/scsi/sg.c:887:14: note: in expansion of macro 'MULDIV' if (val >= MULDIV (INT_MAX, USER_HZ, HZ)) ^ drivers/scsi/sg.c:91:67: warning: integer overflow in expression [-Woverflow] #define MULDIV(X,MUL,DIV) ((((X % DIV) * MUL) / DIV) + ((X / DIV) * MUL)) ^ drivers/scsi/sg.c:888:13: note: in expansion of macro 'MULDIV' val = MULDIV (INT_MAX, USER_HZ, HZ); ^ Avoid this overflow by performing the (constant) arithmetic on 64 bit integers, which ensures that overflow from multiplying the 32 bit values cannot occur. When converting the result back to a 32 bit integer use min_t to ensure that we don't simply truncate a value beyond INT_MAX to a 32 bit integer, but instead use INT_MAX where the result was larger than it. As the values are all compile time constant the 64 bit arithmetic should have no runtime cost.

2016-08-25scsi: ibmvfc: add FC Class 3 Error Recovery supportTyrel Datwyler2-0/+11
The ibmvfc driver currently doesn't support FC Class 3 Error Recovery. However, it is simply a matter of informing the VIOS that the payload expects to use sequence level error recovery via a bit flag in the ibmvfc_cmd structure. This patch adds a module parameter to enable error recovery support at boot time. When enabled the RETRY service parameter bit is set during PRLI, and ibmvfc_cmd->flags includes the IBMVFC_CLASS_3_ERR bit.

2016-08-25scsi: configure runtime pm before calling device_add in scsi_add_host_with_dmaHeiner Kallweit1-4/+8

See also the description in this mail thread https://lists.linuxfoundation.org/pipermail/linux-pm/2009-November/023198.html or the order of calls e.g. in usb_new_device. The changed order also helps to avoid scenarios where runtime pm for &shost->shost_gendev is activated whilst the parent is suspended, resulting in error message "runtime PM trying to activate child device hostx but parent yyy is not active". In addition properly reverse the runtime pm calls in the error path. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Martin K.

2016-08-25scsi: ipr: Add asynchronous error notificationBrian King2-14/+118
This patch implements functions for pushing HCAM (host controlled asynchronous messages) error buffers to userspace through sysfs attributes. Reads to the "async_err_log" attribute will result in a single HCAM buffer being copied to userspace; one can process the next HCAM buffer by writing any string to the same attribute. A new list was added to the ioa_cfg structure to store the HCAM buffers for later reporting. We also send a KOBJ_CHANGE event whenever a new HCAM buffer is made available to userspace.

Add main code for internal abort functionality. The internal abort features allows the host controller to abort commands which are still active in the controller but have not yet been sent to the slave device. Typically a command only spends a relatively short time in the controller when compared to the amount of the time after it is sent to the slave device. Two modes of internal abort are supported: - device - individual command For device, when the internal abort is issued all commands in the host for that device are aborted. For a single command, only that command is aborted if it is still in the host. In HW the internal abort command is executed similar to any other sort of command, like SSP.

The root cause is: - async handle is continued to be used even if it does not match the completion. - list_move operation done on already filled index. 1. Remove use of writables, host_write_ptr and ep_read_ptr. 2. Remove consumed logic to update writables. Instead, use only free_entries to do the accounting of handles to be posted back. 3. Remove busy_list, instead use simple slot to index handles. 4. Added check no data, header less and overflow to make sure all async_handles are flushed in error cases. 5. Added code to verify gathering of handles to form PDU by checking final bit before forwarding PDU. 6. Added code to catch mismatch with CQE and handle gracefully. 7. Use AMAP, traverse cri_wait_queue list to post buffers, log "async PDU" related errors. 8. Rearranged few data structures and added comments in init & processing path. 9.

Other works in wq suffered if the IOCTLs stalled or timed out. This change moves all the boot work to make it non-blocking.

2016-08-23scsi: be2iscsi: Fix to use correct configuration valuesJitendra Bhivare1-3/+3
Following configuration is created with what driver exports: iface.vlan_id = 65535 iface.vlan_priority = 255 iface.vlan_state = <empty> vlan_state is empty as iscsiadm doesn't process "Disabled". When applying this configuration, iscsiadm checks for if vlan_state is "disable" if not it enables with value in vlan_id. 65535 not being valid value, 0 is applied. Use "enable" or "disable" for ISCSI_NET_PARAM. Signed-off-by: Jitendra Bhivare <jitendra.bhivare@broadcom.com> Reviewed-by: Hannes Reinecke <hare@suse.com> Signed-off-by: Martin K.

2016-08-23scsi: fcoe: provide translation table between Ethernet and FC port speedsJohannes Thumshirn1-17/+36
Provide a translation table between Ethernet and FC port speeds so odd speeds (from a Ethernet POV) like 8 Gbit are correctly mapped to sysfs and open-fcoe's fcoeadm.

2016-08-23scsi: cxlflash: Remove adapter file descriptor cacheMatthew R. Ochs2-14/+13
The adapter file descriptor was previously cached within the kernel for a given context in order to support performing a close on behalf of an application. This is no longer needed as applications are now required to perform a close on the adapter file descriptor. Inspired-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Matthew R.

2016-08-23scsi: cxlflash: Transition to application close modelMatthew R. Ochs2-63/+21
Caching the adapter file descriptor and performing a close on behalf of an application is a poor design. This is due to the fact that once a file descriptor in installed, it is free to be altered without the knowledge of the cxlflash driver. This can lead to inconsistencies between the application and kernel. Furthermore, the nature of the former design is more exploitable and thus should be abandoned. To support applications performing a close on the adapter file that is associated with a context, a new flag is introduced to the user API to indicate to applications that they are responsible for the close following the cleanup (detach) of a context. The documentation is also updated to reflect this change in behavior. Inspired-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Matthew R. Ochs <mrochs@linux.vnet.ibm.com> Acked-by: Manoj N.
