scsi: csiostor: Uninitialized data in csio_ln_vnp_read_cbfn()

2021-10-12T16:10:34Z

This variable is just a temporary variable, used to do an endian conversion. The problem is that the last byte is not initialized. After the conversion is completely done, the last byte is discarded so it doesn't cause a problem. But static checkers and the KMSan runtime checker can detect the uninitialized read and will complain about it.

treewide: Use fallthrough pseudo-keyword

2020-08-23T22:36:59Z

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

scsi: csiostor: Don't enable IRQs too early

2019-10-25T01:13:47Z

These are called with IRQs disabled from csio_mgmt_tmo_handler() so we can't call spin_unlock_irq() or it will enable IRQs prematurely.

Merge branch 'fixes' into misc

2018-04-04T00:38:39Z

Somewhat nasty merge due to conflicts between "33b28357dd00 scsi: qla2xxx: Fix Async GPN_FT for FCP and FC-NVMe scan" and "2b5b96473efc scsi: qla2xxx: Fix FC-NVMe LUN discovery" Merge is non-trivial and has been verified by Qlogic (Cavium) Signed-off-by: James E.J. Bottomley

scsi: csiostor: add support for 32 bit port capabilities

32 bit port capabilities are required to support new speeds which can not be supported using 16 bit port capabilities. Signed-off-by: Varun Prakash Signed-off-by: Martin K. Petersen

scsi: csiostor: remove redundant assignment to pointer 'ln'

2018-01-31T02:24:07Z

The pointer ln is assigned a value that is never read, it is re-assigned a new value in the list_for_each loop hence the initialization is redundant and can be removed.

scsi: csiostor: Avoid content leaks and casts

2017-06-13T00:48:05Z

When copying attributes, the len argument was padded out and the resulting memcpy() would copy beyond the end of the source buffer. Avoid this, and use size_t for val_len to avoid all the casts. Similarly, avoid source buffer casts and use void *. Additionally enforces val_len can be represented by u16 and that the DMA buffer was not overflowed. Fixes the size of mfa, which is not FC_FDMI_PORT_ATTR_MAXFRAMESIZE_LEN (but it will be padded up to 4). This was noticed by the future CONFIG_FORTIFY_SOURCE checks.
