Initializing these libfc globals per lport could mess up exch allocation/free for existing lport. So this patch moves their initialization to fc_setup_exch_mgr so that these globals gets initialized only once for libfc. Reported-by:

It's possible and harmless to get FLOGI timeouts while in RESET state. Don't do a WARN_ON in that case. Also, split out the other WARN_ONs in fc_lport_timeout, so we can tell which one is hit by its line number. Signed-off-by:

Fix minor errors. A debug message said an RLIR was received instead of ECHO. "Expected" was misspelled in several places. Fix a type cast from u32 to __be32. Rob, Some of these may have been also taken care of in your other doc cleanup patch. Feel free to fold them in. Signed-off-by:

This bug is exposed when there is a link flap in LLD. Particularly, when it happens right after a SCSI write command is sent out, no FCP_DATA is sent, causing fsp->status_code to be set as FC_DATA_UNDRUN in fc_fcp_complete_locked even no SCSI status is received. Consequently, fc_io_compl treats this as DID_OK. This results in SCSI returning successful to the initial I/O request even there is no DATA actually sent. Particularly, if you run an I/O tool w/ data verification on, the read back for verification is gonna fail. This is fixed here by checking when FC_DATA_UNDRUN happens, SCSI status is received w/ FC_SRB_RCV_STATUS set in fsp->state. Signed-off-by:

xid 0 was used as an indication of invalid xid before but now xid 0 can be used as a valid exchange i. This patch fixes the ddp completion in fcp layer, i.e., in fc_fcp.c:fc_fcp_ddp_done() function, to make sure it does not use xid 0 for indication of an invalid xid, instead, it now uses use FC_XID_UNKNOWN for such indication.

A received Fibre Channel ELS PRLI request contains a bit that indicates whether the remote port supports certain retry processing sequences. The test for this bit was somehow coded to use multiply instead of AND! This case would apply only for target mode operation, and it is unlikely to be noticed as an initiator. Signed-off-by:

Need to grab the host lock around the call to ibmvfc_link_down. Signed-off-by:

Brian King authored
When processing the response to either a LUN reset, target reset, or an abort task set, the ibmvfc driver needs to treat as success receiving a response with a non-zero status in the response IU along with a general transport error with the FCP response code being zero. The VIOS currently guarantees this cannot happen, but a future version of VIOS may allow this to be returned, so ensure we handle this response combination correctly for TMFs, as we already do for SCSI commands.

This version fixes 64-bit modulo on 32-bit as well as inadvertent map updates when TP was disabled. Implement support for thin provisioning in scsi_debug. No actual memory de-allocation is taking place. The intent is to emulate a thinly provisioned storage device, not to be one. There are four new module options: - unmap_granularity specifies the granularity at which to track mapped blocks (specified in number of logical blocks). 2048 (1 MB) is a realistic value for disk arrays although some may have a finer granularity. - unmap_alignment specifies the first LBA which is naturally aligned on an unmap_granularity boundary. - unmap_max_desc specifies the maximum number of ranges that can be unmapped using one UNMAP command. If this is 0, only WRITE SAME is supported and UNMAP will cause a check condition. - unmap_max_blocks specifies the maximum number of blocks that can be unmapped using a single UNMAP command. Default is 0xffffffff. These parameters are reported in the new and extended block limits VPD. If unmap_granularity is specified the device is tagged as thin provisioning capable in READ CAPACITY(16). A bitmap is allocated to track whether blocks are mapped or not. A WRITE request will cause a block to be mapped. So will WRITE SAME unless the UNMAP bit is set. Blocks can be unmapped using either WRITE SAME or UNMAP. No accounting is done to track partial blocks. This means that only whole blocks will be marked free. This is how the array people tell me their firmwares work. GET LBA STATUS is also supported. This command reports whether a block is mapped or not, and how long the adjoining mapped/unmapped extent is. The block allocation bitmap can also be viewed from user space via: /sys/bus/pseudo/drivers/scsi_debug/map Signed-off-by:

I was doing some large lun count testing with 2.6.31 and hit a BUG_ON() in fc_timeout_deleted_rport(), and it seems like it should have been just a matter of time before someone did. It seems invalid to set port_state under lock, then expect it to remain set after releasing the lock. Another thread called fc_remote_port_add() when the lock was released, changing the port_state. This patch removes the BUG_ON and moves the test of the port_state to inside the host_lock. It's been running for several weeks now with no ill effect. Signed-off-by:

When the Integrity check is done in scsi_io_completion it will set error to -EILSEQ. However, at this point error is no longer used, and blk_end_request_err has -EIO hardcoded. It looks like there was just porting mistake with this patch http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=3e695f89c5debb735e4ff051e9e58d8fb4e95110 and we meant to send error upwards, so this patch changes the hard coded EIO to the error variable. I have only boot tested this patch. Signed-off-by:

Workaround 1: For an Errata on LSI53C1030 When the length of request data and transfer data are different with result of command (READ or VERIFY), DID_SOFT_ERROR is set. Workaround 2: For potential trouble on LSI53C1030. It is checked whether the length of request data is equal to the length of transfer and residual. MEDIUM_ERROR is set by incorrect data.
