[SCSI] libiscsi: sync up iscsi and scsi eh's access to the connection

The iscsi eh could be tearing down the session/connection while
the scsi eh is still sending task management functions. If when
we drop the session lock to grab the recv lock, the iscsi eh
tears down the connection we will oops.

[SCSI] libiscsi: fix null ptr regression when aborting a command with data to transfer

We do not want to send data if we are aborting a task. There is
a check in iscsi_xmit_ctask, but right before calling this we overwrite
the state so we always go right past the test. Sending data causes problems
because when we clean up from a successful abort the LLD assumes that
the task is not running.

[GFS2] soft lockup detected in databuf_lo_before_commit

This is part 2 of the patch for bug #245832, part 1 of which is already
in the git tree.

The problem was that sdp->sd_log_num_databuf was not always being
protected by the gfs2_log_lock spinlock, but the sd_log_le_databuf
(which it is supposed to reflect) was protected.  That meant there
was a timing window during which gfs2_log_flush called
databuf_lo_before_commit and the count didn't match what was
really on the linked list in that window.  So when it ran out of
items on the linked list, it decremented total_dbuf from 0 to -1 and
thus never left the "while(total_dbuf)" loop.

The solution is to protect the variable sdp->sd_log_num_databuf so
that the value will always match the contents of the linked list,
and therefore the number will never go negative, and therefore, the
loop will be exited properly.

12 years ago[IPVS]: Use IP_VS_WAIT_WHILE when encessary.
Heiko Carstens [Fri, 10 Aug 2007 22:50:30 +0000]
[IPVS]: Use IP_VS_WAIT_WHILE when encessary.

For architectures that don't have a volatile atomic_ts constructs like
while (atomic_read(&something)); might result in endless loops since a
barrier() is missing which forces the compiler to generate code that
actually reads memory contents.
Fix this in ipvs by using the IP_VS_WAIT_WHILE macro which resolves to
while (expr) { cpu_relax(); }
(why isn't this open coded btw?)

Herbert Xu [Fri, 10 Aug 2007 22:47:58 +0000]
[NET]: Share correct feature code between bridging and bonding

http://bugzilla.kernel.org/show_bug.cgi?id=8797 shows that the
bonding driver may produce bogus combinations of the checksum
flags and SG/TSO.

For example, if you bond devices with NETIF_F_HW_CSUM and
NETIF_F_IP_CSUM you'll end up with a bonding device that
has neither flag set.  If both have TSO then this produces
an illegal combination.

The bridge device on the other hand has the correct code to
deal with this.

In fact, the same code can be used for both.  So this patch
moves that logic into net/core/dev.c and uses it for both
bonding and bridging.

In the process I've made small adjustments such as only
setting GSO_ROBUST if at least one constituent device
supports it.

[DCCP]: fix memory leak and clean up style - dccp_feat_empty_confirm()

There's a memory leak in net/dccp/feat.c::dccp_feat_empty_confirm().  If we
hit the 'default:' case of the 'switch' statement, then we return without
freeing 'opt', thus leaking 'struct dccp_opt_pend' bytes.

The leak is fixed easily enough by adding a kfree(opt); before the return
statement.

CodingStyle.

[IPCONFIG]: ip_auto_config fix

The following commandline:

 root=/dev/mtdblock6 rw rootfstype=jffs2 ip=192.168.1.10:::255.255.255.0:localhost.localdomain:eth1:off console=ttyS0,115200

makes ip_auto_config fall back to DHCP and complain "IP-Config: Incomplete
network configuration information." depending on if CONFIG_IP_PNP_DHCP is
set or not.

The only way I can make ip_auto_config accept my IP config is to add an
entry for the server IP:

ip=192.168.1.10:192.168.1.15::255.255.255.0:localhost.localdomain:eth1:off

I think this is a bug since I am not using a NFS root FS.

The following patch fixes the above problem.

From: Andrew Morton <akpm@linux-foundation.org>

Davem said (in February!):

  Well, first of all the change in question is not in 2.4.x either.  I just
  checked the current 2.4.x GIT tree and the test is exactly:

if (ic_myaddr == INADDR_NONE ||
#ifdef CONFIG_ROOT_NFS
    (MAJOR(ROOT_DEV) == UNNAMED_MAJOR
     && root_server_addr == INADDR_NONE
     && ic_servaddr == INADDR_NONE) ||
#endif
    ic_first_dev->next) {

  which matches 2.6.x

  I even checked 2.4.x when it was branched for 2.5.x and the test was the
  same at the point in time too.

  Looking at the proposed change a bit it appears that it is probably
  correct, as it's trying to check that ROOT_DEV is nfs root.  But if it is
  correct then the UNNAMED_MAJOR comparison in the same code block should be
  removed as it becomes superfluous.

  I'm happy to apply this patch with that modification made.

12 years agoDo not replace whole memcpy in apply alternatives
Petr Vandrovec [Sun, 12 Aug 2007 08:12:52 +0000]
Do not replace whole memcpy in apply alternatives

apply_alternatives uses memcpy() to apply alternatives.  Which has the
unfortunate effect that while applying memcpy alternative to memcpy
itself it tries to overwrite itself with nops - which causes #UD fault
as it overwrites half of an instruction in copy loop, and from this
point on only possible outcome is triplefault and reboot.

So let's overwrite only first two instructions of memcpy - as long as
the main memcpy loop is not in first two bytes it will work fine.

2. disable active trip points (BIOS fan control is broken)
3. disable passive trip point (BIOS hard-codes it too low)

ACPI: thermal: create "thermal.act=" to disable or override active trip point

thermal.act=-1 disables all active trip points
in all ACPI thermal zones.

thermal.act=C, where C > 0, overrides all lowest temperature
active trip points in all thermal zones to C degrees Celsius.
Raising this trip-point may allow you to keep your system silent
up to a higher temperature.  However, it will not allow you to
raise the lowest temperature trip point above the next higher
trip point (if there is one).  Lowering this trip point may
kick in the fan sooner.

Note that overriding this trip-point will disable any BIOS attempts
to implement hysteresis around the lowest temperature trip point.
This may result in the fan starting and stopping frequently
if temperature frequently crosses C.

WARNING: raising trip points above the manufacturer's defaults

Len Brown [Sun, 12 Aug 2007 04:12:44 +0000]
ACPI: thermal: create "thermal.nocrt" to disable critical actions

thermal.nocrt=1 disables actions on _CRT and _HOT
ACPI thermal zone trip-points.  They will be marked
as <disabled> in /proc/acpi/thermal_zone/*/trip_points.

There are two cases where this option is used:

1. Debugging a hot system crossing valid trip point.

   If your system fan is spinning at full speed,
   be sure that the vent is not clogged with dust.
   Many laptops have very fine thermal fins that are easily blocked.

   Check that the processor fan-sink is properly seated,
   has the proper thermal grease, and is really spinning.

   Check for fan related options in BIOS SETUP.
   Sometimes there is a performance vs quiet option.
   Defaults are generally the most conservative.

   If your fan is not spinning, yet /proc/acpi/fan/
   has files in it, please file a Linux/ACPI bug.

   WARNING: you risk shortening the lifetime of your
   hardware if you use this parameter on a hot system.
   Note that this refers to all system components,

2. Working around a cool system crossing critical
   trip point due to erroneous temperature reading.

   Try again with CONFIG_HWMON=n
   There is known potential for conflict between the

ACPI: thermal: create "thermal.psv=" to override passive trip points

"thermal.psv=-1" disables passive trip points
for all ACPI thermal zones.

"thermal.psv=C", where 'C' is degrees Celsius,
overrides all existing passive trip points
for all ACPI thermal zones.

thermal.psv is checked at module load time,

Note that if the system does not deliver thermal zone
temperature change events near the new trip-point,
then it will not be noticed.  To force your custom
trip point to be noticed, you may need to enable polling:
eg. thermal.tzp=3000 invokes polling every 5 minutes.

Note that once passive thermal throttling is invoked,
it has its own internal Thermal Sampling Period (_TSP),
that is unrelated to _TZP.

12 years agoACPI: thermal: expose "thermal.tzp=" to set global polling frequency
Len Brown [Sun, 12 Aug 2007 04:12:26 +0000]
ACPI: thermal: expose "thermal.tzp=" to set global polling frequency

Thermal Zone Polling frequency (_TZP) is an optional ACPI object
recommending the rate that the OS should poll the associated thermal zone.

If _TZP is 0, no polling should be used.
If _TZP is non-zero, then the platform recommends that
the OS poll the thermal zone at the specified rate.
The minimum period is 30 seconds.
The maximum period is 5 minutes.

(note _TZP and thermal.tzp units are in deci-seconds,
 so _TZP = 300 corresponds to 30 seconds)

If _TZP is not present, ACPI 3.0b recommends that the
thermal zone be polled at an "OS provided default frequency".

However, common industry practice is:
1. The BIOS never specifies any _TZP
2. High volume OS's from this century never poll any thermal zones

Ie. The OS depends on the platform's ability to
provoke thermal events when necessary, and
the "OS provided default frequency" is "never":-)

There is a proposal that ACPI 4.0 be updated to reflect
common industry practice -- ie. no _TZP, no polling.

The Linux kernel already follows this practice --
thermal zones are not polled unless _TZP is present and non-zero.

But thermal zone polling is useful as a workaround for systems
which have ACPI thermal control, but have an issue preventing
thermal events.  Indeed, some Linux distributions still
set a non-zero thermal polling frequency for this reason.

But rather than ask the user to write a polling frequency
into all the /proc/acpi/thermal_zone/*/polling_frequency
files, here we simply document and expose the already
existing module parameter to do the same at system level,
to simplify debugging those broken platforms.

Note that thermal.tzp is a module-load time parameter only.
