The following series adds the following code to the SCSI subsystem.
1) FC and FCoE protocol definitions in header files
- Files are added in include/scsi/fc/
- New files are: fc_els.h, fc_encaps.h, fc_fc2.h,
fc_fcp.h, fc_fs.h, fc_gs.h and fc_ns.h
2) libfc - a FC assist library
- Composed of 5 sub-components: Exchange Manager, Local Port
Remote Port, Discovery and SCSI-FCP
- Uses libfc_function_template for cross-layer calls
- Uses struct fc_lport as primary object shared by all
sub-modules
- Common code defined in include/scsi/libfc.h
3) fcoe - a FCoE initiator implementation
- Simple encapsulation and unpacking layer
- Interacts with netdev
- Initial support for FCoE offload
- Uses /sys/module/fcoe/parameters/create and destroy for
enabling/disabling FCoE connection over a particular Ethernet
adapter
- Works on any Ethernet adapter
These patches apply to both the scsi-misc and scsi-rc-fixes trees.
I beleive that we've addressed each of Andi's comments. The largest being
a security review where we mostly focused on input validation from the wire
as well as removing BUG_ON and WARN_ON statements that could be initiated
from an external entity. For a detailed list of recent activity please view
our git log on Open-FCoE. Here is a link to our gitweb site:
http://www.open-fcoe.org/openfc/gitweb/?p=openfc/open-fcoe-initiator.git;a=summary
We did not break the patch-set down any further as it would not be bisect-able.
Our libfc blocks are organized by file, so using splitdiff or diffsplit anyone
should be able to break these patches down into smaller, more review friendly
chunks.
Locking comments are mostly in comment blocks at the tops of some files. The
largest comment block is in drivers/scsi/libfc/fc_lport.c and would be a good
starting point when reviewing the locking.
