Russell King - ARM Linux d5ccd67bb7 NET: smc91x: Fix irq flags
smc91x.h defines SMC_IRQ_FLAGS to be -1 when it wants the interrupt
flags to be taken from the resource structure.  However, d280ead
changed this to checking for non-zero resource flags.

Unfortunately, this means that on some platforms, we end up passing
'-1' to request_irq rather than the desired result.  Combine the two
conditions into one so that the IRQ flags are taken from the resource
if either SMC_IRQ_FLAGS is -1 or the resource flags specify an
interrupt trigger.

This restores network on at least the Versatile platform.

Ivan Vecera cc098dc705 r8169: restore mac addr in rtl8169_remove_one and rtl_shutdown
The newer chipsets (all PCI-E) are known that they need full power cycle
(AC or battery removal) to reset MAC address to a  hardwired one. Previous
patch to address this problem loads the original MAC address from EEPROM.
But it brought other problem for which it is necessary to introduce a new
module parameter.
However, it might suffice to restore the initial MAC address before
shutdown/reboot/kexec and when removing the module.

David Ford bbf31bf18d ipv4: additional update of dev_net(dev) to struct *net in ip_fragment.c, NULL ptr OOPS
ipv4 ip_frag_reasm(), fully replace 'dev_net(dev)' with 'net', defined
previously patched into 2.6.29.

Between 2.6.28.10 and 2.6.29, net/ipv4/ip_fragment.c was patched,
changing from dev_net(dev) to container_of(...).  Unfortunately the goto
section (out_fail) on oversized packets inside ip_frag_reasm() didn't
get touched up as well.  Oversized IP packets cause a NULL pointer
dereference and immediate hang.

I discovered this running openvasd and my previous email on this is
titled:  NULL pointer dereference at 2.6.32-rc8:net/ipv4/ip_fragment.c:566

Alan Stern 862f89b3d4 PM: fix irq enable/disable in runtime PM code
This patch (as1305) fixes a bug in the irq-enable settings and removes
some related overhead in the runtime PM code.

	In __pm_runtime_resume(), within the scope of the original
	spin_lock_irq(), we know that irqs are disabled.  There's no
	reason to go through a pair of enable/disable cycles when
	acquiring and releasing the parent's lock.

	In __pm_runtime_set_status(), irqs are already disabled when
	the parent's lock is acquired, and they must remain disabled
	when it is released.

Andrei Pelinescu-Onciul 5fdd4baef6 sctp: on T3_RTX retransmit all the in-flight chunks
When retransmitting due to T3 timeout, retransmit all the
in-flight chunks for the corresponding  transport/path, including
chunks sent less then 1 rto ago.
This is the correct behaviour according to rfc4960 section 6.3.3
E3 and
"Note: Any DATA chunks that were sent to the address for which the
 T3-rtx timer expired but did not fit in one MTU (rule E3 above)
 should be marked for retransmission and sent as soon as cwnd
 allows (normally, when a SACK arrives). ".

This fixes problems when more then one path is present and the T3
retransmission of the first chunk that timeouts stops the T3 timer
for the initial active path, leaving all the other in-flight
chunks waiting forever or until a new chunk is transmitted on the
same path and timeouts (and this will happen only if the cwnd
allows sending new chunks, but since cwnd was dropped to MTU by
the timeout => it will wait until the first heartbeat).

Example: 10 packets in flight, sent at 0.1 s intervals on the
primary path. The primary path is down and the first packet
timeouts. The first packet is retransmitted on another path, the
T3 timer for the primary path is stopped and cwnd is set to MTU.
All the other 9 in-flight packets will not be retransmitted
(unless more new packets are sent on the primary path which depend
on cwnd allowing it, and even in this case the 9 packets will be
retransmitted only after a new packet timeouts which even in the
best case would be more then RTO).

This commit reverts d0ce92910b and
also removes the now unused transport->last_rto, introduced in
 b6157d8e03.

p.s  The problem is not only when multiple paths are there.  It
can happen in a single homed environment.  If the application
stops sending data, it possible to have a hung association.

The comment in fuse_open about O_DIRECT:

  "VFS checks this, but only _after_ ->open()"

also holds for fuse_create, however, the same kind of check was missing there.

As an impact of this bug, open(newfile, O_RDWR|O_CREAT|O_DIRECT) fails, but a
stub newfile will remain if the fuse server handled the implied FUSE_CREATE
request appropriately.

Other impact: in the above situation ima_file_free() will complain to open/free

Alexey Kuznetsov 4e46bf8997 [SCSI] fix crash when disconnecting usb storage
__scsi_remove_device() in scsi_forget_host() is executed out of scan_mutex
and races with scsi_destroy_sdev() <- scsi_sysfs_add_devices() <-
scsi_finish_async_scan().  The result is use after free and/or double
free, oops.

The fix is simple, move scsi_forget_host() under scan_mutex.

scsi_forget_host() is just sequence of __scsi_remove_device().  All
another calls of __scsi_remove_device() are made under scan_mutex.  So
that it is safe.

James Bottomley 860dc73608 [SCSI] fix async scan add/remove race resulting in an oops
Async scanning introduced a very wide window where the SCSI device is
up and running but has not yet been added to sysfs.  We delay the
adding until all scans have completed to retain the same ordering as
sync scanning.

This delay in visibility causes an oops if a device is removed before
we make it visible because the SCSI removal routines have an inbuilt
assumption that if a device is in SDEV_RUNNING state, it must be
visible (which is not necessarily true in the async scanning case).

Fix this by introducing an additional is_visible flag which we can use
to condition the tear down so we do the right thing for running but
not yet made visible.

Currently, ide_cmd_ioctl when invoked for setting DMA transfer mode calls
ide_find_dma_mode with requested mode as XFER_UDMA_6. This prevents setting DMA
mode to any other value than the default (maximum) supported by the device (or
UDMA6, if supported) irrespective of the actual requested transfer mode and
returns error.

For example, setting mode to UDMA2 using hdparm, where UDMA4 is the default
transfer mode gives following error:
	# ./hdparm -d1 -Xudma2  /dev/hda
	 /dev/hda:hda: UDMA/66 mode selected
	 setting using_dma to 1 (on)
	 hda: UDMA/66 mode selected
	 setting xfermode to 66 (UltraDMA mode2)

Ironically, the atomic testset instruction cannot be interrupted else it
will produce incorrect results.  So disable interrupts to help it out.

Mike Frysinger af5d7fc7e4 Blackfin: update anomaly lists
Add some recently documented anomalies (473, 474, 475, 477).  Also stick
a "do not edit" notice in here so people know these are copies of some

Michael Hennerich 865bddfbf7 Blackfin: fix suspend/resume failure with some on-chip ROMs
Some Blackfin on-chip ROMs utilize some MDMA channels during the suspend
and resume process, but don't clean up after themselves.  So manually
clear all DMA channels when resuming since no DMA could have been running
at this point in time.  Now Linux should be able to work regardless of any
laziness on the part of the on-chip ROM or boot loader.

Henrique de Moraes Holschuh 275014ae46 thinkpad-acpi: fix detection of old ThinkPads
There is a problem in the quirk tables used by tpacpi_is_fw_known() and
tpacpi_check_outdated_fw(), which causes outdated BIOSes that are lacking
the EC firmware ID DMI field to never match.

This breaks module loading on, e.g.  a T23 with outdated BIOS, and the
module will refuse to load unless the "force_load=1" parameter is given.

Fix the quirk tables so that they can also match the outdated BIOSes,
which in turn will both fix the module loading, and also warn the user
that he is using outdated firmware and should upgrade.

This fixes a serious regression, introduced by commit
e675abafcc, "thinkpad-acpi: be more strict
when detecting a ThinkPad".

Alexey Starikovskiy d0b3b119f4 ACPICA: Silence the warning about _BIF returning the buffer
_BIF was returning buffer instead of a string since day 1 of ACPI.
Adding a warning for that is noble, but people don't like
when someone cries wolf in a production system.
