By this time I have reworked the update of scripts/generate-kernel-patch'>scripts/generate-kernel-patch.
These are the changes that were already present in version 1 of this patch
and that have been kept in this patch:
- The SCST code has been moved from drivers/scsi/scsi_tgt to drivers/scst.
- Moved SCST header files from include/scsi_tgt to include/scst.
- Added iscsi-scst in drivers/scst/iscsi-scst.
For the time being the generate-kernel-patch does no longer try to add the
qla2x00t driver in drivers/scst/qla2x00-target -- I have not yet been able to
figure out how to get qla2x00t/qla2x00-target compiled without the initiator
code.
Just as in version 1 of this patch, the following files in the Subversion
repository have been renamed to reflect the above changes:
- Renamed scst/kernel/in-tree/Makefile.scsi.Linux-2.6.24.patch'>scst/kernel/in-tree/Makefile.scsi.Linux-2.6.24.patch to
scst/kernel/in-tree/Makefile.drivers.Linux-2.6.24.patch'>scst/kernel/in-tree/Makefile.drivers.Linux-2.6.24.patch.
- Renamed Kconfig'>scst/kernel/in-tree/Kconfig.scsi.Linux-2.6.24.patch to
scst/kernel/in-tree/Kconfig.drivers.Linux-2.6.24.patch'>scst/kernel/in-tree/Kconfig.drivers.Linux-2.6.24.patch.
- Renamed scst/kernel/in-tree/Makefile.scsi_tgt'>scst/kernel/in-tree/Makefile.scsi_tgt to
scst/kernel/in-tree/Makefile.scst'>scst/kernel/in-tree/Makefile.scst.
- Renamed scst/kernel/in-tree/Kconfig.scsi_tgt'>scst/kernel/in-tree/Kconfig.scsi_tgt to
scst/kernel/in-tree/Kconfig.scst'>scst/kernel/in-tree/Kconfig.scst.
Because of the above changes the include path specified in the following
Makefiles had to be changed:
- scst/kernel/in-tree/Makefile.dev_handlers'>scst/kernel/in-tree/Makefile.dev_handlers
- srpt/src/Makefile.in_kernel'>srpt/src/Makefile.in_kernel
Other changes:
- I have added menu/endmenu entries in file scst/kernel/in-tree/Kconfig.scst
such that the SCST entries become visible when running make xconfig or make
menuconfig.
- Elaborated the SCST help texts a little bit (in file
scst/kernel/in-tree/Kconfig.scst).
New in version 2 of this patch:
- Moved remaining patches in the generate-kernel-patch script to separate
files.
- Added support for the 2.6.25 kernel.
This patch has been tested as follows:
mkdir -p tmp
cd tmp
rm -rf linux-2.6.25.3 /lib/modules/2.6.25.3-scst
tar xjf ~vanasscb/software/downloads/linux-2.6.25.3.tar.bz2
cd linux-2.6.25.3
cp ../.config-2.6.25 .
(cd ~vanasscb/software/scst
&& ~vanasscb/software/scst/scripts/generate-kernel-patch \
2.6.25) | patch -p1
make oldconfig
diff ../.config .
make xconfig
make menuconfig
make -j5 bzImage modules
make modules_install install
cp -r /lib/firmware/$(uname -r) /lib/firmware/2.6.25.3-scst
update-initramfs -k 2.6.25.3-scst -c
reboot
modprobe iscsi-scst
modprobe ib_srpt
lsmod | grep -E 'scst|ib_srpt'
dmesg

- Minor external interface change: now target drivers should set for aborted commands SCST_CMD_DELIVERY_ABORTED status via scst_set_delivery_status(). In-tree drivers updated.
- Fixed broken compilation if put_page_callback patch not applied to the kernel. Reported by Erez Zilber <erezz@Voltaire.COM>
- Fixed several minor problems reported by David Berton <davidbrt@yahoo.com>
- Fixed __exit misuse, when such functions called from __init functions.
- Docs updated.
- Other minor changes and cleanups.
git-svn-id: http://svn.code.sf.net/p/scst/svn/trunk@364 d57e44dd-8a1f-0410-8b47-8ef2f437770f
- "RECEIVE DIAGNOSTIC RESULTS" command handling fixed
- Obtaining device queue parameters in scst_obtain_device_parameters() changed to handle NOT READY sense
- Fixed possible dev_cmd_count underflow
- Minor iSCSI-SCST connection closing cleanups and fixes
- Semantic of other *_atomic flags changed a bit. Now they are intended only to allow SCST to optimize execution context. The corresponing functions now can *always* be called on atomic context and, if necessary, should manually determine that using scst_cmd_atomic() function and restart using corresponding *_NEED_THREAD_* return value.
- scst_cmd_get_tgt_resp_flags() and SCST_TSC_FLAG_STATUS flag made obsolete and replaced by scst_cmd_get_is_send_status(). All in-tree drivers updated accordingly
- Cleanup: preprocessing_done_atomic removed, now preprocessing_done() callback always called on thread context
- 64-bit cleanups
- Documented that iscsi-scst-adm is currently broken and explained why
- In user space Makefile's added possibility to specify external linker flags
- Minor performance optimizations
- Other minor cleanups

- Response data send timeout implemented: now if initiator doesn't accept data for too long (7 sec), target closes connection
- Connction closing improved: now session cleared without need to wait for all outstanding commands data fully transmitted
- On session unregistration now all outstanding commands are implicitely aborted
- TM processing in SCST core made independant from other TM commands (before they were serialized)
- Few bug fixes
- Other minor improvements and cleanups
- Docs update

1. The kernel's log level is a string, so strcmp needs to be used for
comparisons.
2. Svn HEAD doesn't compile against kernel versions < 2.6.19 because
"bool" had its debut only in 2.6.19. Here's a quick fix.
3. Iscsi-scstd dies with SIGPIPE if run in foreground mode because the reading
end of the init_report_pipe is already closed in this mode.
