11 years agosvcrdma: Limit ORD based on client's advertised IRD
Tom Tucker [Tue, 20 May 2008 00:00:24 +0000]
svcrdma: Limit ORD based on client's advertised IRD

When adapters have differing IRD limits, the RDMA transport will fail to
connect properly. The RDMA transport should use the client's advertised
inbound read limit when computing its outbound read limit. For iWARP
transports, there is currently no standard for exchanging IRD/ORD
during connection establishment so the 'responder_resources' field in the
connect event is the local device's limit. The RDMA transport can be
configured to use a smaller ORD by writing the desired number to the
/proc/sys/sunrpc/svc_rdma/max_outbound_read_requests file.

11 years agonfsd: treat all shutdown signals as equivalent
Jeff Layton [Mon, 30 Jun 2008 18:09:46 +0000]
nfsd: treat all shutdown signals as equivalent

knfsd currently uses 2 signal masks when processing requests. A "loose"
mask (SHUTDOWN_SIGS) that it uses when receiving network requests, and
then a more "strict" mask (ALLOWED_SIGS, which is just SIGKILL) that it
allows when doing the actual operation on the local storage.

This is apparently unnecessarily complicated. The underlying filesystem
should be able to sanely handle a signal in the middle of an operation.
This patch removes the signal mask handling from knfsd altogether. When
knfsd is started as a kthread, all signals are ignored. It then allows
all of the signals in SHUTDOWN_SIGS. There's no need to set the mask
as well.

11 years agonfsd: fix spurious EACCESS in reconnect_path()
Neil Brown [Thu, 8 May 2008 03:03:09 +0000]
nfsd: fix spurious EACCESS in reconnect_path()

Thanks to Frank Van Maarseveen for the original problem report: "A
privileged process on an NFS client which drops privileges after using
them to change the current working directory, will experience incorrect
EACCES after an NFS server reboot. This problem can also occur after
memory pressure on the server, particularly when the client side is
quiet for some time."

This occurs because the filehandle points to a directory whose parents
are no longer in the dentry cache, and we're attempting to reconnect the
directory to its parents without adequate permissions to perform lookups
in the parent directories.

We can therefore fix the problem by acquiring the necessary capabilities
before attempting the reconnection.  We do this only in the
no_subtree_check case, since the documented behavior of the
subtree_check export option requires the server to check that the user
has lookup permissions on all parents.

The subtree_check case still has a problem, since reconnect_path()
unnecessarily requires both read and lookup permissions on all parent
directories.  However, a fix in that case would be more delicate, and
use of subtree_check is already discouraged for other reasons.

x86: fix cpu hotplug crash

Vegard Nossum reported crashes during cpu hotplug tests:

  http://marc.info/?l=linux-kernel&m=121413950227884&w=4

In function _cpu_up, the panic happens when calling
__raw_notifier_call_chain at the second time. Kernel doesn't panic when
calling it at the first time. If just say because of nr_cpu_ids, that's
not right.

By checking the source code, I found that function do_boot_cpu is the culprit.
Consider below call chain:
 _cpu_up=>__cpu_up=>smp_ops.cpu_up=>native_cpu_up=>do_boot_cpu.

So do_boot_cpu is called in the end. In do_boot_cpu, if
boot_error==true, cpu_clear(cpu, cpu_possible_map) is executed. So later
on, when _cpu_up calls __raw_notifier_call_chain at the second time to
report CPU_UP_CANCELED, because this cpu is already cleared from
cpu_possible_map, get_cpu_sysdev returns NULL.

Many resources are related to cpu_possible_map, so it's better not to
change it.

Below patch against 2.6.26-rc7 fixes it by removing the bit clearing in
cpu_possible_map.

11 years agosched: fix cpu hotplug
Dmitry Adamushko [Sat, 28 Jun 2008 22:16:56 +0000]
sched: fix cpu hotplug

the CPU hotplug problems (crashes under high-volume unplug+replug
tests) seem to be related to migrate_dead_tasks().

Firstly I added traces to see all tasks being migrated with
migrate_live_tasks() and migrate_dead_tasks(). On my setup the problem
pops up (the one with "se == NULL" in the loop of
pick_next_task_fair()) shortly after the traces indicate that some has
been migrated with migrate_dead_tasks()). btw., I can reproduce it
much faster now with just a plain cpu down/up loop.

[disclaimer] Well, unless I'm really missing something important in
this late hour [/desclaimer] pick_next_task() is not something
appropriate for migrate_dead_tasks() :-)

the following change seems to eliminate the problem on my setup
(although, I kept it running only for a few minutes to get a few
messages indicating migrate_dead_tasks() does move tasks and the
system is still ok)

V4L/DVB (8108): Fix open/close race in saa7134

The saa7134 driver uses a (non-atomic) variable in an attempt to
only allow one opener of the device (how it deals with sending
the fd over unix sockets I don't know).

Unfortunately, the release function first decrements this variable,
and THEN goes on to disable more of the device. This allows for
a race where another opener of the device comes in after the decrement of
the variable, configures the hardware just to then see the hardware
be disabled by the rest of the release function.

This patch makes the release function use the same lock as the open
function to protect the hardware as well as the variable (which now
at least has some locking to protect it).

V4L/DVB (8034): tda18271: fix IF notch frequency handling

The IF notch bit gets unset when we update the Main Post Div register
value, before we have a chance to write the desired IF notch setting
to the tuner.  Move the IF notch configuration to after we update MPD.

V4L/DVB (8029): Improve error message at tda1004x_attach

When an error occurs at firmware loading, sometimes, tda1004x stops answering.
Instead of reporting such error, attach code were assuming that the device were
answering an invalid ID (0xff). This can be seen when enabling debug options:

tda1004x: tda1004x_read_byte: reg=0x0
tda1004x: tda1004x_read_byte: error reg=0x0, ret=-5

Now, instead of reporting an invalid ID, it will report the correct error:

tda10046: chip is not answering. Giving up.
saa7133[0]/dvb: failed to attach tda10046
saa7133[0]/dvb: frontend initialization failed

A possible improvement would be trying to reset the device.

V4L/DVB (8028): Improve error messages for tda1004x attach

A fresh copy of v.29 firmware, using get_firmware, is leading to an invalid
firmware:

DVB: registering new adapter (saa7133[0])
DVB: registering frontend 0 (Philips TDA10046H DVB-T)...
tda1004x: setting up plls for 48MHz sampling clock
tda1004x: found firmware revision ff -- invalid
tda1004x: trying to boot from eeprom
tda1004x: found firmware revision ff -- invalid
tda1004x: waiting for firmware upload...
tda1004x: Error during firmware upload
tda1004x: found firmware revision ff -- invalid
tda1004x: firmware upload failed

Sometimes, loading/unloading this firmware makes tda1004x to return an invalid
ID. However, there were no printk messages to help to identify what were the
cause for the error.

With this patch, it will now print:

Invalid tda1004x ID = 0xff. Can't proceed
saa7133[0]/dvb: failed to attach tda10046
saa7133[0]/dvb: frontend initialization failed

Blackfin arch: fix bug - kernel boot fails when Spinlock and rw-lock debugging enabled

Initialize the lock of bad_irq_desc properly.
The content of irq_desc array is replaced by bad_irq_desc in blackfin
arch irqchip init code. So, do it properly as common irq init code.

[PATCH] remove useless argument type in audit_filter_user()

The second argument "type" is not used in audit_filter_user(), so I think that type can be removed. If I'm wrong, please tell me.
