2017-06-28scsi: bnx2fc: If IO is still in cleanup then do not return to SCSI layer.Chad Dupuis1-8/+3
In eh_abort, driver is calling scsi->done() for a IO for which cleanup is pending. As the IO is outstanding with the firmware, it may do DMA associated with the IO. This may lead to heap corruption. Do not complete the IO for which cleanup is still pending. Return failure from eh_abort and let the SCSI-ml retry the IO. Signed-off-by: Chad Dupuis <chad.dupuis@cavium.com> Signed-off-by: Martin K.

2017-06-16networking: make skb_put & friends return void pointersJohannes Berg1-1/+1
It seems like a historic accident that these return unsigned char *, and in many places that means casts are required, more often than not. Make these functions (skb_put, __skb_put and pskb_put) return void * and remove all the casts across the tree, adding a (u8 *) cast only where the unsigned char pointer was used directly, all done with the following spatch: @@ expression SKB, LEN; typedef u8; identifier fn = { skb_put, __skb_put }; @@ - *(fn(SKB, LEN)) + *(u8 *)fn(SKB, LEN) @@ expression E, SKB, LEN; identifier fn = { skb_put, __skb_put }; type T; @@ - E = ((T *)(fn(SKB, LEN))) + E = fn(SKB, LEN) which actually doesn't cover pskb_put since there are only three users overall. A handful of stragglers were converted manually, notably a macro in drivers/isdn/i4l/isdn_bsdcomp.c and, oddly enough, one of the many instances in net/bluetooth/hci_sock.c. In the former file, I also had to fix one whitespace problem spatch introduced. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-07-13fcoe: convert to kworkerSebastian Andrzej Siewior1-4/+4
The driver creates its own per-CPU threads which are updated based on CPU hotplug events. It is also possible to use kworkers and remove some of the kthread infrastrucure. The code checked ->thread to decide if there is an active per-CPU thread. By using the kworker infrastructure this is no longer possible (or required). The thread pointer is saved in `kthread' instead of `thread' so anything trying to use thread is caught by the compiler. Currently only the bnx2fc driver is using struct fcoe_percpu_s and the kthread member. After a CPU went offline, we may still enqueue items on the "offline" CPU. This isn't much of a problem. The work will be done on a random CPU. The allocated crc_eof_page page won't be cleaned up. It is probably expected that the CPU comes up at some point so it should not be a problem. The crc_eof_page memory is released of course once the module is removed. This patch was only compile-tested due to -ENODEV. Cc: Vasu Dev <vasu.dev@intel.com> Cc: "James E.J.

When we are in connection recovery and the internal command timer on a request pops, either the scsi_cmnd->device or scsi_cmnd->device->host back pointers may be NULL as the device that the command that the request was submitted on may have been subsequently reaped due to the connection recovery. This can cause one or both of the pointers above to be NULL and cause a system crash if we try to return the command to the midlayer. Instead, double check the pointers before the return to the midlayer so as to prevent the crash and let the upper layers finish the session recovery and rediscover the device.

2015-11-10scsi: use host wide tags by defaultChristoph Hellwig1-1/+0
This patch changes the !blk-mq path to the same defaults as the blk-mq I/O path by always enabling block tagging, and always using host wide tags. We've had blk-mq available for a few releases so bugs with this mode should have been ironed out, and this ensures we get better coverage of over tagging setup over different configs.

2015-11-10bnx2fc: reduce stack usage in __bnx2fc_enableArnd Bergmann1-4/+9
When the bnx2fc driver was changed to read the npiv table from nvram, the stack of the __bnx2fc_enable function gained an additional 1028 byte structure that gcc rightfully warns about: drivers/scsi/bnx2fc/bnx2fc_fcoe.c: In function '__bnx2fc_enable': drivers/scsi/bnx2fc/bnx2fc_fcoe.c:2134:1: warning: the frame size of 1128 bytes is larger than 1024 bytes [-Wframe-larger-than=] In order to avoid a possible kernel stack overflow and to get rid of the warning, this changes the function to use a dynamic allocation of the structure using kzalloc.

Since we got rid of ordered tag support in 2010 the prime use case of switching on and off ordered tags has been obsolete. The other function of enabling/disabling tagging entirely has only been correctly implemented by the 53c700 driver and isn't generally useful.

2014-11-24scsi: avoid ->change_queue_depth indirection for queue full trackingChristoph Hellwig1-0/+1
All drivers use the implementation for ramping the queue up and down, so instead of overloading the change_queue_depth method call the implementation diretly if the driver opts into it by setting the track_queue_depth flag in the host template. Note that a few drivers validated the new queue depth in their change_queue_depth method, but as we never go over the queue depth set during slave_configure or the sysfs file this isn't nessecary and can safely be removed.

2014-11-20bnx2fc: do not add shared skbs to the fcoe_rx_listMaurizio Lombardi1-0/+7
In some cases, the fcoe_rx_list may contains multiple instances of the same skb (the so called "shared skbs"). the bnx2fc_l2_rcv thread is a loop that extracts a skb from the list, modifies (and destroys) its content and then proceed to the next one. The problem is that if the skb is shared, the remaining instances will be corrupted. The solution is to use skb_share_check() before adding the skb to the fcoe_rx_list.
