scsi: megaraid_sas: Return pended IOCTLs with cmd_status MFI_STAT_WRONG_STATE in case adapter is dead After a kill adapter, since the cmd_status is not set, the IOCTLs will be hung in driver resulting in application hang. Set cmd_status MFI_STAT_WRONG_STATE when completing pended IOCTLs. Signed-off-by:

Driver's local RAID map is accessed frequently. We will first try to get memory from __get_free_pages. If this fails, fall back to using vmalloc. For crash dump buffers always prefer vmalloc. Signed-off-by:

scsi: megaraid_sas: Call megasas_complete_cmd_dpc_fusion every 1 second while there are pending commands megasas_wait_for_outstanding_fusion checks for pending commands every 1 second. But megasas_complete_cmd_dpc_fusion is only called every 5 seconds. If the commands are already completed by firmware, there is an additional delay of 5 seconds before driver will process completion for these commands. Signed-off-by:

scsi: megaraid_sas: mismatch of allocated MFI frame size and length exposed in MFI MPT pass through command Driver allocated 256 byte MFI frames bytes but while sending MFI frame (embedded inside chain frame of MPT frame) to firmware, driver sets the length as 4k.

Take f_mutex around mmap() processing to protect against races with the SG_SET_RESERVED_SIZE ioctl. Ensure the reserve buffer length remains consistent during the mapping operation, and set the "mmap called" flag to prevent further changes to the reserved buffer size as an atomic operation with the mapping.

Commit 1bc0eb04 ("scsi: sg: protect accesses to 'reserved' page array") adds needed concurrency protection for the "reserve" buffer. Some checks that are initially made outside the lock are replicated once the lock is taken to ensure the checks and resulting decisions are made using consistent state. The check that a request with flag SG_FLAG_MMAP_IO set fits in the reserve buffer also needs to be performed again under the lock to ensure the reserve buffer length compared against matches the value in effect when the request is linked to the reserve buffer. An -ENOMEM should be returned in this case, instead of switching over to an indirect buffer as for non-MMAP_IO requests. Signed-off-by:

If scsi_host_template->host_reset is NULL and the user requests an adapter reset through echo adapter > /sys/class/scsi_host/hostx/host_reset -EINVAL will be returned even though the "adapter" argument is perfectly valid. Change this so that we only return -EINVAL if the provided string is invalid. If the host does not implement a ->host_reset function we'll return -EOPNOTSUPP.

Currently in the driver the qedf_ctx attribute vlan_hw_insert is used to which whether to insert a VLAN tag in FIP frames (except for FIP VLAN request which is explicitly sent out untagged at least from the driver's point of view). When we receive a FIP VLAN response, we set qedf->vlan_hw_insert to 0 which makes the qedf_fip_send function insert the VLAN. However when we exhaust our FIP VLAN retries, we do not set qedf->vlan_hw_insert to 0 which means that the driver will not tag the FIP frame with the correct VLAN ID. The result that was observed on the wire is that some entity either in the LL2 or L2 firmware is adding a NULL VLAN tag which can cause FIP solicitation to fail. The offload FCoE frame function, qedf_xmit, does not use the vlan_hw_insert attribute to decide whether to tag frames with the FIP/FCoE VLAN. Instead it unilaterially tags the offload frames with the VLAN ID stored in qedf->vlan_id. This is the correct behavior so the driver can guarantee that non-offload FIP frames go out with the correct VLAN ID. Also use the Linux network layer helpers instead of doing the VLAN insert manually. Also fix setting the fallback VLAN so that it used the module parameter and is not hardcoded to 1002 (though 1002 is the default). [mkp: fixed typo] Signed-off-by:

Currently in the driver we've been using the fc_fcoe_set_mac() function to set the source MAC for FCoE traffic. This works well in most cases as it uses the spec. default FCF-MAC. However, if the administrator changes the FCF-MAC switch, then any FCoE traffic we send will be dropped by the switch. Instead we should check the granted MAC from the FLOGI payload and use that address if it is present. Otherwise, fall back to using the the default FCF-MAC and the fabric ID of the port as the FCoE MAC address. Once this address is known we need to set it when doing non-offload traffic, offload traffic and setting the data_src_address libfcoe uses for FIP keep alive messages. Signed-off-by:

The code looks like this: i = ntohl(aux->filemark_cnt); if (STp->header_cache != NULL && i < OS_FM_TAB_MAX && (i > STp->filemark_cnt || STp->first_frame_position - 1 != ntohl(STp->header_cache->dat_fm_tab.fm_tab_ent[i]))) { If i is negative then it's less than OS_FM_TAB_MAX so we read before the start of the STp->header_cache->dat_fm_tab.fm_tab_ent[] array.
