If a pathgroup is established we get an event and have to revalidate
the server to propagate supported features like PAV and enable them.

Remove the optimization that validate server is only called once per
LCU. If a device is set online we only know that we already know the
LCU. But if the pathgroup was lost in between we have to do a
validate server again to activate some features.
Since we have no indication when a pathgroup gets lost we have to do
a validate server every time a device is set online.

The vmlinux file for s390 contains a currently unused entry point,
which is specified in two different locations: the linker script
and the makefile. As it happens both definitions are different and
the linker file is broken (_start does not exist) and the makefile
specifies an entry point which makes no sense (the SALIPL loader
entry point).
So lets get rid of one definition (the makefile) and use the entry
point of all other ipl methods (0x10000 -> startup) to be consistent.

This patch addresses a bug with sendtargets discovery where INADDR_ANY (0.0.0.0)
+ IN6ADDR_ANY_INIT ([0:0:0:0:0:0:0:0]) network portals where incorrectly being
reported back to initiators instead of the address of the connecting interface.
To address this, save local socket ->getname() output during iscsi login setup,
and makes iscsit_build_sendtargets_response() return these TargetAddress keys
when INADDR_ANY or IN6ADDR_ANY_INIT portals are in use.

We need to handle >1 page control cdbs, so extend the code to do a vmap

A statement such as
struct iscsi_node_attrib *na = na = iscsit_tpg_get_node_attrib(sess);
has undefined behaviour since there are two assignments to 'na', strictly
speaking (the order in which side-effects from the assignments take place
is undefined since there's no intervening sequence point), and it looks
unintentional in any case.

This patch adds a work-around for handling zero allocation length
control CDBs (type SCF_SCSI_CONTROL_SG_IO_CDB) that was causing an
OOPs with the following raw calls:
# sg_raw -v /dev/sdd 3 0 0 0 0 0
# sg_raw -v /dev/sdd 0x1a 0 1 0 0 0
This patch will follow existing zero-length handling for data I/O
and silently return with GOOD status. This addresses the zero length
issue, but the proper long-term resolution for handling arbitary
allocation lengths will be to refactor out data-phase handling in
individual CDB emulation logic within target_core_cdb.c

According to SPC-4, the sense key for commands that are failed with
INVALID FIELD IN PARAMETER LIST and INVALID FIELD IN CDB should be
ILLEGAL REQUEST (5h) rather than ABORTED COMMAND (Bh). Without this
patch, a tcm_loop LUN incorrectly gives:
# sg_raw -r 1 -v /dev/sda 3 1 0 0 ff 0
Sense Information:
Fixed format, current; Sense key: Aborted Command
Additional sense: Invalid field in cdb
Raw sense data (in hex):
70 00 0b 00 00 00 00 0a 00 00 00 00 24 00 00 00
00 00
While a real SCSI disk gives:
Sense Information:
Fixed format, current; Sense key: Illegal Request
Additional sense: Invalid field in cdb
Raw sense data (in hex):
70 00 05 00 00 00 00 18 00 00 00 00 24 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
with the main point being that the real disk gives a sense key of
ILLEGAL REQUEST (5h).

Doing alloc_page(GFP_KERNEL | __GFP_ZERO) to get pages used for data
buffers wastes a lot of CPU clearing pages that will be quickly be
overwritten by the actual data. However, for emulated control
commands such as INQUIRY and so on, the code does assume that the
buffer is zeroed.
To avoid this CPU overhead, skip the __GFP_ZERO for commands that are
actually moving data, ie cmds that have SCF_SCSI_DATA_SG_IO_CDB set.

Advantage (beside cleanup) is that other data of the pr (acpi_processor) struct

Kdump kernels leave MSI-X interrupts (as setup by the crashed kernel)
enabled. However, kdump only enables one CPU in the new environment,
thus causing tg3 to abort MSI-X setup. When the driver attempts to
enable INTA or MSI interrupt modes on a kdump kernel, interrupt
delivery fails.
This patch attempts to workaround the problem by forcing the driver
to enable a single MSI-X interrupt. In such a configuration, the
device's multivector interrupt mode must be disabled.

Look for a key of type "secret" with a description of

then scrape the username and password out of the key payload and use
that to create a new user session.

For CIFS, we want to be able to store NTLM credentials (aka username
and password) in the keyring. We do not, however want to allow users
to fetch those keys back out of the keyring since that would be a
security risk.
Unfortunately, due to the nuances of key permission bits, it's not
possible to do this. We need to grant search permissions so the kernel
can find these keys, but that also implies permissions to read the
payload.
Resolve this by adding a new key_type. This key type is essentially
the same as key_type_user, but does not define a .read op. This
prevents the payload from ever being visible from userspace. This
key type also vets the description to ensure that it's "qualified"
by checking to ensure that it has a ':' in it that is preceded by
other characters.

JONGMAN HEO reports:
With current linus git (commit a25a2b84), I got following build error,
arch/x86/kernel/vm86_32.c: In function 'do_sys_vm86':
arch/x86/kernel/vm86_32.c:340: error: implicit declaration of function '__audit_syscall_exit'
make[3]: *** [arch/x86/kernel/vm86_32.o] Error 1
OK, I can reproduce it (32bit allmodconfig with AUDIT=y, AUDITSYSCALL=n)
It's due to commit d7e7528bcd45: "Audit: push audit success and retcode
into arch ptrace.h".
