Vladislav Bolkhovitin 102603f46d We can't mark sess as shutting down in close_conn(), because at that time it might have pending commands. Otherwise, in case of reinstatement it might lead to data corruption, because commands in being reinstated session can be executed after commands in the new session.

Vladislav Bolkhovitin bc96b052d5 The patch below adds support for the 2.6.29 kernel and also fixes the
checkpatch issues reported by the checkpatch script included with the 2.6.29
kernel and that were not yet reported by the 2.6.28 checkpatch script
(trailing statements should be on the next line / struct should normally be
const).
The patch below has been tested as follows:
- Reran scripts/run-regression-tests -k 2.6.24.7 -k 2.6.25.20 -k 2.6.26.8 -k 2.6.27.21 -k 2.6.28.9 -k 2.6.29 and verified the output.
- Rebuilt, installed and loaded scst, iscsi-scst and srpt as follows:
make -s clean && make -s -C scst install && make -s -C iscsi-scst install && make -s -C srpt install && cd scstadmin && make -s && make -s install && modprobe scst_vdisk && modprobe iscsi-scst && dmesg

Vladislav Bolkhovitin d5322f10ad The patch below implements the following changes for the iSCSI-SCST HOWTO
document:
- Added RHEL / CentOS to the list of officially supported kernels.
- Mentioned that regenerating the initial RAM disk is an explicit step on many
  distro's.
- Replaced shell instructions for generating /etc/scst.conf by a sequence of
  scstadmin commands.
- Added note about insserv.

Also it adds small HOWTO how to recompile RHEL/CentOS kernel in README_RHEL.

Also it implements some docs cleanups.

Vladislav Bolkhovitin dd1400dddc The patch below adds the following two RHEL 5 / CentOS 5 patches to the SCST
source tree:
- Support for zero-copy TCP transfer completion.
- An implementation of scsi_execute_async_fifo().
Except for the hunk headers, these patches are identical to similarly named
patches already present in the SCST source tree.

Additionally, implementations of seq_list_start() and seq_list_next() are
provided for those kernel versions that do not define these functions.

The patch below has been tested by verifying that iSCSI data transfer still
works OK on CentOS 5.2 (x86_64).

Vladislav Bolkhovitin ae5ec143aa The patch below is a minor correction for the 2.6.27 in-tree kernel patches
I submitted about three months ago: the patch headers now refer to the 2.6.27
kernel as they should instead of the 2.6.26 kernel. At least one user has been
confused by this. The patch below does not change any behavior of SCST.
The patch has been tested by verifying that the output of the following
command remained the same as before the modifications:
scripts/run-regression-tests -k 2.6.27

- Introduce min*/max*() and more list_* macros

 - Multipart PDU support for discovery sessions

The conn's response buffer is now replaced with a list of buffers and
all users are updated accordingly. Discovery sessions can make use of
this mechanism, if the list of targets + addresses does not fit into a
single text PDU, the initiator may now retrieve subsequent parts.

This also fixes the data segment handling for discovery sessions.

- Update MaxConnections documentation
 - Remove isns config description from man page
 - Check return values of chdir(), ftruncate() and write(), because recent versions of the glibc insist on the return value being checked by
introducing __attribute__((warn_unused_result)) to these functions.
 - Fix snprintf use in isns.c
 - Take \0-termination into account when passing strings to isns_tlv_set() to solve incompatibility with MS iSNS 3.0 as IQN length is multiple of 4
 - Fix list corruption if SCST target registration fails
 - Register the target port actually used instead of the default iSCSI port.
 - Remove unused connection->pad
 - Refactor cmnd_execute()
 - Version changed
