It seems some iSCSI targets (including the Linux kernel target) close the TCP connection from the target side immediately after processing a session logout. When a TCP FIN comes in right after the iSCSI logout response, iscsi_sw_sk_state_check sees the local socket as not yet being in CLOSE_WAIT or CLOSE and logs an error. But the initiator would close the connection right after processing the logout response anyway, and the error is confusing to admins who just requested that the session be shut down. This adds a check of the session state, and suppresses the error if we are in the process of logging out. Signed-off-by:

It makes no sense to flush the cache of a device without medium. Errors during suspend must be handled according to their causes. Errors due to missing media or unplugged devices must be ignored. Errors due to devices being offlined must also be ignored. The error returns must be modified so that the generic layer understands them.

Somehow older areca firmware versions have issues with scsi_get_vpd_page() and a large buffer, the firmware seems to crash and the scsi error-handler will start endless recovery retries. Limiting the buf-size to 64-bytes fixes this issue with older firmware versions (<1.49 for my controller). Fixes a regression with areca controllers and older firmware versions introduced by commit: 66c28f97Reported-by:

Each member in data integrity field tuple is big-endian. But the endianness of the values being compared with these members are not annotated. So this fixes these sparse warnings. Reported-by:

In the module initialization, invalid value for guard module parameter is detected by the following check: if (scsi_debug_guard > 1) { printk(KERN_ERR "scsi_debug_init: guard must be 0 or 1\n"); return -EINVAL; } But this check isn't enough, because the type of scsi_debug_guard is 'int' and scsi_debug_guard could be a negative value. This fixes it by changing the type of scsi_debug_guard to 'unsigned int' instead of adding extra check for a negative value. Reported-by:Joe Perches <joe@perches.com> Signed-off-by:

If data integrity support is enabled, prot_verify_write() is called in response to WRITE commands and it verifies protection info from prot_sglist by comparing against data sglist, and copies protection info to dif_storep. When multiple blocks are transfered by a WRITE command, it verifies and copies these blocks one by one. So if it fails to verify protection info in the middle of blocks, the actual data transfer to fake_storep isn't proceeded at all although protection info for some blocks are already copied to dif_storep. Therefore, it breaks the data integrity between fake_storep and dif_storep. This fixes it by ensuring that copying protection info to dif_storep is done after all blocks are successfully verified. Reusing dif_copy_prot() with supporting the opposite direction simplifies this fix. Signed-off-by:

If data integrity support is enabled, prot_verify_read() is called in response to READ commands and it verifies protection info from dif_storep by comparing against fake_storep, and copies protection info to prot_sglist. This factors out the portion of copying protection info into a separate function. It will also be reused in the next change after supporting the opposite direction (copying prot_sglist to dif_storep). Signed-off-by:

If the module parameter virtual_gb is greater than 0, the READ command may request the blocks which exceed actual ramdisk storage (fake_storep). prot_verify_read() should treat those blocks as wrap around the end of fake_storep. But it actually causes fake_storep and dif_storep buffer overruns. This fixes these buffer overruns. In order to simplify the fix, this also introduces fake_store() and dif_store() which return corresponding wrap around addresses. Signed-off-by:
