[TCP]: Prevent pseudo garbage in SYN's advertized window
TCP may advertize up to 16-bits window in SYN packets (no window
scaling allowed). At the same time, TCP may have rcv_wnd
(32-bits) that does not fit to 16-bits without window scaling
resulting in pseudo garbage into advertized window from the
low-order bits of rcv_wnd. This can happen at least when
mss <= (1<<wscale) (see tcp_select_initial_window). This patch
fixes the handling of SYN advertized windows (compile tested
only).
In worst case (which is unlikely to occur though), the receiver
advertized window could be just couple of bytes. I'm not sure
that such situation would be handled very well at all by the
receiver!? Fortunately, the situation normalizes after the
first non-SYN ACK is received because it has the correct,
scaled window.
Alternatively, tcp_select_initial_window could be changed to
prevent too large rcv_wnd in the first place.

The problem here is that the void cast causes return types to not be
promoted, and for ops such as listxattr which expect more than 32 bits of
return value, the 32-bit -EIO is interpreted as a large positive 64-bit
number, i.e. 0x00000000fffffffa instead of 0xfffffffa.
This goes particularly badly when the return value is taken as a number of
bytes to copy into, say, a user's buffer for example...
I originally had coded up the fix by creating a return_EIO_<TYPE> macro
for each return type, like this:
but Al felt that it was probably better to create an EIO-returner for each
actual op signature. Since so few ops share a signature, I just went ahead
& created an EIO function for each individual file & inode op that returns
a value.

I encountered a kernel panic with my test program, which is a very
simple IPv6 client-server program.
The server side sets IPV6_RECVPKTINFO on a listening socket, and the
client side just sends a message to the server. Then the kernel panic
occurs on the server. (If you need the test program, please let me
know. I can provide it.)
This problem happens because a skb is forcibly freed in
tcp_rcv_state_process().
When a socket in listening state(TCP_LISTEN) receives a syn packet,
then tcp_v6_conn_request() will be called from
tcp_rcv_state_process(). If the tcp_v6_conn_request() successfully
returns, the skb would be discarded by __kfree_skb().
However, in case of a listening socket which was already set
IPV6_RECVPKTINFO, an address of the skb will be stored in
treq->pktopts and a ref count of the skb will be incremented in
tcp_v6_conn_request(). But, even if the skb is still in use, the skb
will be freed. Then someone still using the freed skb will cause the
kernel panic.
I suggest to use kfree_skb() instead of __kfree_skb().

fix umask when noACL kernel meets extN tuned for ACLs
Fix insecure default behaviour reported by Tigran Aivazian: if an
ext2 or ext3 filesystem is tuned to mount with "acl", but mounted by
a kernel built without ACL support, then umask was ignored when creating
inodes - though root or user has umask 022, touch creates files as 0666,
and mkdir creates directories as 0777.
This appears to have worked right until 2.6.11, when a fix to the default
mode on symlinks (always 0777) assumed VFS applies umask: which it does,
unless the mount is marked for ACLs; but ext[23] set MS_POSIXACL in
s_flags according to s_mount_opt set according to def_mount_opts.
We could revert to the 2.6.10 ext[23]_init_acl (adding an S_ISLNK test);
but other filesystems only set MS_POSIXACL when ACLs are configured. We
could fix this at another level; but it seems most robust to avoid setting
the s_mount_opt flag in the first place (at the expense of more ifdefs).

reiserfs: avoid tail packing if an inode was ever mmapped
This patch fixes a confusion reiserfs has for a long time.
On release file operation reiserfs used to try to pack file data stored in
last incomplete page of some files into metadata blocks. After packing the
page got cleared with clear_page_dirty. It did not take into account that
the page may be mmaped into other process's address space. Recent
replacement for clear_page_dirty cancel_dirty_page found the confusion with
sanity check that page has to be not mapped.
The patch fixes the confusion by making reiserfs avoid tail packing if an
inode was ever mmapped. reiserfs_mmap and reiserfs_file_release are
serialized with mutex in reiserfs specific inode. reiserfs_mmap locks the
mutex and sets a bit in reiserfs specific inode flags.
reiserfs_file_release checks the bit having the mutex locked. If bit is
set - tail packing is avoided. This eliminates a possibility that mmapped
page gets cancel_page_dirty-ed.

loopback adfs image on a 2.6.17-rc5 x86_64 machine, and the patch fixed it
there.
Include connector config in the s390 arch Kconfig to get support for
connectors.
This also fixes the following Kconfig warning:
fs/Kconfig:1728:warning: 'select' used by config symbol 'CIFS_UPCALL' refer to undefined symbol 'CONNECTOR'

NETFILTER: NAT: fix NOTRACK checksum handling
The whole idea with the NOTRACK netfilter target is that
you can force the netfilter code to avoid connection
tracking, and all costs assosciated with it, by making
traffic match a NOTRACK rule.
But this is totally broken by the fact that we do a checksum
calculation over the packet before we do the NOTRACK bypass
check, which is very expensive. People setup NOTRACK rules
explicitly to avoid all of these kinds of costs.
This patch from Patrick, already in Linus's tree, fixes the
bug.
Move the check for ip_conntrack_untracked before the call to
skb_checksum_help to fix NOTRACK excemptions from NAT. Pre-2.6.19
NAT code breaks TSO by invalidating hardware checksums for every
packet, even if explicitly excluded from NAT through NOTRACK.
2.6.19 includes a fix that makes NAT and TSO live in harmony,
but the performance degradation caused by this deserves making
at least the workaround work properly in -stable.
