Bart Van Assche 58eb630bd0 Fixed the issue that 'rmmod ib_srpt' with ongoing SRP I/O could trigger 
a deadlock.

Bart Van Assche 745a852fbe - Fixed a buffer overrun: a service entry name occupying 35 bytes was 
written into a buffer with a size of 32 bytes. Enlarged the buffer
  to 36 bytes.
- Converted sprintf() calls to snprintf() calls.
- Added more TRACE_ENTRY() / TRACE_EXIT() statements.

Bart Van Assche 57f4019ed5 Moved /sys/class/infiniband_srpt/trace_level to 
/proc/scsi_tgt/ib_srpt/trace_level such that the behavior of the
ib_srpt target is consistent with that of other SCST drivers.

Bart Van Assche 5d67fefe37 - Fixed a race condition found via source reading: srpt_remove_one() did not 
wait until srpt_refresh_port_work() finished. This race condition could be
  triggered during module removal.
- Added a kernel module parameter called "trace_flag" that allows to set the
  trace flags for the ib_srpt module before module initialization starts.
- Added sysfs variable /sys/class/infiniband_srpt/trace_level that allows to
  display and to modify the enabled trace flags in a human-readable form.
- Added several TRACE_ENTRY() / TRACE_EXIT() statements.
- Added more comments.

Bart Van Assche 262a538807 - Compiles again on RHEL 5. 
- RHEL 5 + OFED: fixed kernel oops that was triggered by the reception of
  an asynchronous InfiniBand event.

Bart Van Assche 7519550fcb Moved scst_register() call from srpt_detect() to srpt_add_one(). Added 
call to scst_unregister() in srpt_remove_one(). Result:
- The kernel oops triggered by loading the ib_srpt kernel module before
  the InfiniBand subnet manager became active is now fixed.
- It is now possible to log in via the SRP protocol through HCA's that
  became active after the ib_srpt kernel module finished module
  initialization.

Bart Van Assche 106acdb7d6 - Switched to a more traditional error handling style with regard to MAD 
handler registration: sport->mad_agent is now reset to NULL when MAD
  handler registration fails.
- Fixed bug in srpt_refresh_port(): this function now returns a negative
  value instead of zero when MAD registration fails.

Bart Van Assche c712d12f40 The function srpt_cm_req_recv() now returns an error code instead of 0 
when an SRP login request is rejected. This fixes a memory leak: the
InfiniBand core (drivers/infiniband/core/cm.c) only calls cm_free_work()
when the registered cm_handler function, i.e. srpt_cm_req_recv()
returns an error code. This patch has been submitted by by Frank Zago.

Bart Van Assche c3d3378bc2 Made show_login_info() work for InfiniBand HCA's with more than two 
ports. show_login_info() produces the information that can be retrieved
from /sys/class/infiniband_srpt/srpt-*/login_info. Note: as of today
there do not yet exist any InfiniBand HCA's with more than two ports.
Thanks to Frank Zago for reporting this issue.
