Support Virtual Disk(VDI,VHD,VMDK) by VirtualBox DSO (VBoxDDU.so).
Use ADAPTIVE_NP for some mutex.
Decrese mutex lock time at transfer task.
Print # of reload count to syslog.
LU updating (except connected LU).
Ignore reload error, and retry next reload by SIGUP.
Use gcc 4.1 atomic builtin functions.
Fix some memory leak at exit.
Accept up to two SCSI commands in one LUN loop.
Omit inaccessible PG on SendTargets. (when multiple PG specified)
Faster normal exit.
Remove extra warning by clang.
Add NetBSD rc script.
Major changes:
- Introduce SIGHUP reloading.
- The symlink device can be enabled by '--enable-symlink-device' configure
option.
- Fix the unknown error under some mutex condition.
- Fix the wrong reservation key handling.
- Use Clang as first choice compiler.
- Use _GNU_SOURCE on linux platform.
Current Limitations of SIGHUP support:
- The parameters other than PG, IG, and LU are not reloaded by SIGHUP.
- PG and IG mapped to LU can't be deleted by SIGHUP.
- If you delete an active LU, all connections of the LU are closed by
SIGHUP.
- Can't modify LU by SIGHUP.
- Updating IG is not affected until the next login.
Includes Makefile patch sent upstream (thanks!).
Changelog (translated by Google from Japanese):
Adjust the duration of the lock, and make additional response
SendTargets.
Added ReadCache / WriteCache as a LUN option for future expansion.
This volatile write cache mode was previously supported with (O_FSYNC)
,but can now be set from the beginning.
It is expected to be stable this year.
New configuration key (LUN option):
# for each LUN number (both enabled by default)
LUN0 Option ReadCache Disable
LUN0 Option WriteCache Disable
Many bugs are fixed. Especially, a memory leak in queuing.
And it have new experimental multi-threaded mode.
(QueueDepth with -m1 command line option)
In this mode, it improves I/O delay such as small random R/W.
It is also intended to use Quad or more core CPU and 10Gbps link.
Main changelog is in Japanese. Author says:
Main changes:
support auto size of block device at various OS. (includes
NetBSD,MacOSX,Linux)
remove ZFS and /usr/local from src.
remove unused config.
Also includes patches from pkgsrc fed upstream (thanks Daisuke!).
(refer to RFC3720 about iSCSI) for FreeBSD 7.1 or later.
It includes iSCSI protocol processor and SPC-3 (SCSI Primary
Commands - 3) based logical unit emulation.
