14 years agokgdb: 1000 loops for the single step test in kgdbts
Jason Wessel [Thu, 24 Apr 2008 21:57:23 +0000 (16:57 -0500)]
kgdb: 1000 loops for the single step test in kgdbts

The single step test is not terribly costly and it should be able to
pass at 1000 loops successfully in under 1 second.  A non-kgdb timing
regression was found using this test, but it did not occur frequently
because by default the test was only executed a single time.

This patch changes the default for the single step test to 1000
iterations and allows for individual configuration of the single step
test to further exercise the kgdb subsystem when needed.

14 years agoMake forced module loading optional
Linus Torvalds [Mon, 5 May 2008 00:04:16 +0000 (17:04 -0700)]
Make forced module loading optional

The kernel module loader used to be much too happy to allow loading of
modules for the wrong kernel version by default.  For example, if you
had MODVERSIONS enabled, but tried to load a module with no version
info, it would happily load it and taint the kernel - whether it was
likely to actually work or not!

Generally, such forced module loading should be considered a really
really bad idea, so make it conditional on a new config option
(MODULE_FORCE_LOAD), and make it default to off.

If somebody really wants to force module loads, that's their problem,
but we should not encourage it.  Especially as it happened to me by
mistake (ie regular unversioned Fedora modules getting loaded) causing
lots of strange behavior.

x86: remove dell reboot dmi quirk board name match

http://bugzilla.kernel.org/show_bug.cgi?id=10547

Newer Dell OptiPlex 745s hang before rebooting after 'sudo reboot'.

A patch for some versions of the OptiPlex was proposed here --
http://lkml.org/lkml/2007/6/5/59 -- and is included in 2.6.23 and
later kernels, according to
http://lxr.linux.no/linux+v2.6.23/arch/i386/kernel/reboot.c . However,
the DMI_BOARD_NAME ("0WF810") is too restrictive. Newer OptiPlex
machines have a DMI_BOARD_NAME of "0RF703".  I therefore suggest
adding another clause to reboot.c, similar to the one in the original
patch, but matching a DMI_BOARD_NAME of "0RF703".

On further inspection, it seems that there are other DMI_BOARD_NAMEs
for this same machine. They seem to change from time to time, which
means that the current code is fragile. Moreover, using bios reboot
should not break non-SFF OptiPlex 745s, and so a reasonable fix is to
simply drop the match on DMI_BOARD_NAME.

14 years agomodpost: i2c aliases need no trailing wildcard
Jean Delvare [Fri, 2 May 2008 18:37:21 +0000 (20:37 +0200)]
modpost: i2c aliases need no trailing wildcard

Not all device types need a wildcard at the end of their module
aliases. In particular, for i2c module aliases, the trailing wildcard
is not only unneeded, it could also cause the wrong driver to be
loaded.

As I2C devices have no IDs, i2c module aliases are simple, arbitrary
device names. For example:

$ /sbin/modinfo lm90
filename:       /lib/modules/2.6.25-git18/kernel/drivers/hwmon/lm90.ko
author:         Jean Delvare <khali@linux-fr.org>
description:    LM90/ADM1032 driver
license:        GPL
vermagic:       2.6.25-git18 mod_unload
depends:        hwmon
alias:          i2c:lm90*
alias:          i2c:adm1032*
alias:          i2c:lm99*
alias:          i2c:lm86*
alias:          i2c:max6657*
alias:          i2c:adt7461*
alias:          i2c:max6680*
$

This would cause trouble if one I2C chip name matches the beginning of
another I2C chip name and both chips are supported by different
drivers. For example, an i2c device named lm9042 would cause the lm90
driver to be loaded, while it doesn't support that device. This case
has yet to be seen in practice, but still, I'd like to fix it now. The
cleanest fix is to remove the trailing wildcard from i2c module aliases.

Here's a patch doing this.

Not all device type aliases need a trailing wildcard, in particular
the i2c aliases don't. Don't add a wildcard by default in do_table(),
instead let each device type handler add it if needed.

I have tested types acpi, dmi, eisa, i2c, ide, ieee1394, input, pci,
pcmcia, platform, pnp, scsi, serio, ssb and usb. Other types (ccw, of,
vio, parisc, sdio and virtio) are untested.

This replaces the duplicated arch-specific versions of "sys_pipe()" with

code.

It's marked __weak, so that *if* an architecture wants to override the
default implementation it can do so by simply having its own replacement
version, since many architectures use alternate calling conventions for

implementations often return the two file descriptors in registers)

Daniel Lezcano [Sat, 3 May 2008 00:00:58 +0000 (17:00 -0700)]
netns: Fix device renaming for sysfs

When a netdev is moved across namespaces with the
'dev_change_net_namespace' function, the 'device_rename' function is
used to fixup kobject and refresh the sysfs tree. The device_rename
function will call kobject_rename and this one will check if there is
an object with the same name and this is the case because we are
renaming the object with the same name.

The use of 'device_rename' seems for me wrong because we usually don't
rename it but just move it across namespaces. As we just want to do a
mini "netdev_[un]register", IMO the functions
'netdev_[un]register_kobject' should be used instead, like an usual
network device [un]registering.

This patch replace device_rename by netdev_unregister_kobject,
followed by netdev_register_kobject.

The netdev_register_kobject will call device_initialize and will raise
a warning indicating the device was already initialized. In order to
fix that, I split the device initialization into a separate function
and use it together with 'netdev_register_kobject' into
register_netdevice. So we can safely call 'netdev_register_kobject' in
'dev_change_net_namespace'.

This fix will allow to properly use the sysfs per namespace which is
coming from -mm tree.

and is largely transparent to the driver, except...

It turns out that the UMP firmware needs to know the current status

firmware will not operate correctly.
