The foce_softc mem was reserved by libfc_host_alloc as well as by fcoe_host_alloc. Removes one liner fcoe_host_alloc completely, instead directly calls libfc_host_alloc to alloc scsi_host with libfc for just one fcoe_softc as fcoe private data. Moves libfc_host_alloc to libfc.h since it is a libfc API, placed lport_priv API adjacent to libfc_host_alloc since this is related to scsi_host priv data. Signed-off-by:

Removes no where used several inline functions prefixed with skb_* and be16_to_cpu. Moves fcoe module specific func prototypes to fcoe.c from libfcoe.h, moved only need for build. Adds fcoe module header file fcoe.h and then moves fcoe module specific fcoe_percpu_s and fcoe_softc to fcoe.h from libfcoe.h. Moves all defines from fcoe.c to fcoe.h since now fcoe module has its own header file fcoe.h. [jejb: removed EXPORT_SYMBOL_GPL(fcoe_fc_crc) which caused a section mismatch] Signed-off-by:

Moves these functions as-is from fcoe.c to libfcoe.c, since they're are common routines: - fcoe_wwn_from_mac - fcoe_libfc_config Signed-off-by:

Just sets up build environment for libfcoe module towards a libfcoe library for libfc LLDs using FCoE as libfc transport. Common library code to libfcoe is added in next patch. Also, updated MODULE_LICENSE from "GPL" string to "GPL v2" for libfc, libfcoe and fcoe modules to accurately match the licenses. Signed-off-by:

Renames libfcoe.c to fcoe.c, fcoe.c becomes the only .c file for fcoe.ko. Also deleted "$Id: Makefile" from fcoe module Makefle. Signed-off-by:

Moves only required code from fcoe_sw.c to libfcoe.c towards having just one source file for fcoe module, this gets rid off default sw transport code in a separate fcoe_sw.c file. Very minor renaming along this move, dropped _sw_ or _SW_ use in names and replaced them by _if_ as a auxiliary interface functions. Now some of these funcs can be removed or merged with other func after fcoe transport is gone, but that should be in another patch to keep this patch simple. Now the libfcoe.c file name for fcoe module doesn't go along well, so the libfcoe.c file renaming to fcoe.c as the only single fcoe module file is done in next patch to keep this patch clean and small for review.

Remove unused fc_transport_fcoe.c and fc_transport_fcoe.h files. Signed-off-by: -
Vasu Dev authored
The fcoe transport code was added for generic FCoE transport infrastructure to allow additional offload related module loading on demand, this is not required anymore after recently added different offload approach by having offload related func ops in netdev. This patch removes fcoe transport related code use, calls functions directly between existing libfcoe.c and fcoe_sw.c for now, for example fcoe_sw_destroy and fcoe_sw_create calling. The fcoe_sw.c and libfcoe.c code will be further consolidated in later patches and then also the default fcoe sw transport code file fcoe_sw.c will be completely removed. The fcoe transport code files are completely removed in next patch to keep this patch simple for reviewing. [This patch is an update to a previous patch. This update resolves a build error as well as fixes a defect related to not calling fc_release_transport().] Signed-off-by:

This patch adds support for dynamically created Rx threads upon CPU hotplug events. There were existing synchronization problems that this patch attempts to resolve. The main problem had to do with fcoe_rcv() running in a different context than the hotplug notifications. This opened the possiblity that fcoe_rcv() would target a Rx thread for a skb. However, that thread could become NULL if the CPU was made offline. This patch uses the Rx queue's (a skb_queue) lock to protect the thread it's associated with and we use the 'thread' member of the fcoe_percpu_s to determine if the thread is ready to accept new skbs. The patch also attempts to do a better job of cleaning up, both if hotplug registration fails as well as when the module is removed.

Remove the hotplug creation of dev_stats, we allocate for all possible CPUs now when we allocate the lport. v2: Durring the 2.6.30 merge window, before these patches were comitted, 'percpu_ptr' was renamed 'per_cpu_ptr'. This latest update updates this patch for the name change. Signed-off-by:

Convert fcoe_percpu array to use the per-cpu variables that the kernel provides. Use the kernel's functions to access this structure. The cpu member of the fcoe_percpu_s is no longer needed, so this patch removes it too. Signed-off-by:

Currently the skb_queue is initialized every time the associated CPU goes online. This patch has libfcoe initializing the skb_queue for all possible CPUs when the module is loaded. This patch also re-orders some declarations in the fcoe_rcv() function so the structure declarations are grouped before the primitive declarations. Lastly, this patch converts all CPU indicies to use unsigned int since CPU indicies should not be negative. Signed-off-by:

A fix for a very serious and stupid bug in osd_initiator. It used to call blk_put_request() regardless of if it was from the end_io callback or if called after a sync execution. It should call the unlocked version __blk_put_request() instead. Also fixed is the remove of _abort_unexecuted_bios hack, and use of blk_end_request(,-ERROR,) to deallocate half baked requests. I've audited the code and it should be safe. Reported and Tested-by:

We have a problem with recovered error handling in that any command which goes down as BLOCK_PC but which returns a sense code of RECOVERED ERROR gets completed with -EIO. For actual SG_IO commands, this doesn't matter at all, since the error return code gets dropped in favour of req->errors which contain the SCSI completion code. However, if this command is part of the block system, then it will pay attention to the returned error code. In particularly if a SYNCHRONIZE CACHE from a barrier command completes with RECOVERED ERROR, the resulting -EIO on the barrier causes block to error the request and return it to the filesystem. Fix this by converting the -EIO for recovered error to zero, plus remove the printing of this from sd and sr so the message isn't double printed. Signed-off-by: -

aic79xx leaves timers inserted when ahd_init() (which inserts two timers at its very end) succeeds but ahd_pci_map_int() fails. In this case ahd->init_level gets incremented to 5 only when that function succeeds, but ahd_free() calls ahd_shutdown() only when ahd->init_level == 5, and ahd_shutdown() is where the timers get removed. Since the freeing of the IRQ is not controlled by ahd->init_level, we should increment init_level prior to calling ahd_pci_map_int(). Reported-by:

Firmware semantics changed for 24xx and above ISPs in their handling of the specified execution-throttle passed during firmware initialization. The original codes use of a theoretical maximum (0xffff, as carried over from earlier ISPs) could in fact act as a throttle in some circumstances. Now set the value based of the firmware's own 'resource' (exchange IOCBs) capabilities. Signed-off-by:

The original code to 'resize request-queues' based on iocb-counts and employed during early ISP23xx testing was too overly-pessimistic with regards to latencies in the firmware pulling requests. Recent ISPs can easily keep up processing a stream of commands from an abbreviated (effectively, half the original size) queue. Signed-off-by:

When IRQs are shared by multiple controllers and if the first one to register does not disable the IRQ, then IRQ will be enabled for all other controllers by default, irrespective of their setting. With IRQF_DISABLED registration, the driver interrupt routine was called with interrupt enabled always. Disbaling the registration with IRQF_DISABLED, since driver code is re-entrant safe and all critical sections are guarded with interrupt safe locks. Signed-off-by:

Given the low-level interface varies from one flash-part manufacturer to the next, the Flash-Access-Control (FAC) mailbox command makes the specific flash type transparent to the driver by encapsulating a basic set of accessor and update routines.
