      Linux Kernel Markers: create modpost file · b2e3e658
      由 Mathieu Desnoyers 提交于 
      This adds some new magic in the MODPOST phase for CONFIG_MARKERS.  Analogous
to the Module.symvers file, the build will now write a Module.markers file
when CONFIG_MARKERS=y is set.  This file lists the name, defining module, and
format string of each marker, separated by \t characters.  This simple text
file can be used by offline build procedures for instrumentation code,
analogous to how System.map and Module.symvers can be useful to have for
kernels other than the one you are running right now.

The strings are made easy to extract by having the __trace_mark macro define
the name and format together in a single array called __mstrtab_* in the
__markers_strings section.  This is straightforward and reliable as long as
the marker structs are always defined by this macro.  It is an unreasonable
amount of hairy work to extract the string pointers from the __markers section
structs, which entails handling a relocation type for every machine under the
sun.

      Linux Kernel Markers: support multiple probes · fb40bd78
      由 Mathieu Desnoyers 提交于 
      RCU style multiple probes support for the Linux Kernel Markers.  Common case
(one probe) is still fast and does not require dynamic allocation or a
supplementary pointer dereference on the fast path.

- Move preempt disable from the marker site to the callback.

Since we now have an internal callback, move the preempt disable/enable to the
callback instead of the marker site.

Since the callback change is done asynchronously (passing from a handler that
supports arguments to a handler that does not setup the arguments is no
arguments are passed), we can safely update it even if it is outside the
preempt disable section.

- Move probe arm to probe connection. Now, a connected probe is automatically
  armed.

Remove MARK_MAX_FORMAT_LEN, unused.

This patch modifies the Linux Kernel Markers API : it removes the probe
"arm/disarm" and changes the probe function prototype : it now expects a
va_list * instead of a "...".

If we want to have more than one probe connected to a marker at a given
time (LTTng, or blktrace, ssytemtap) then we need this patch. Without it,
connecting a second probe handler to a marker will fail.

It allow us, for instance, to do interesting combinations :

Do standard tracing with LTTng and, eventually, to compute statistics
with SystemTAP, or to have a special trigger on an event that would call
a systemtap script which would stop flight recorder tracing.

      pcmcia: ipwireless depends on NETDEVICES · 9170d2f6
      由 Paul Mundt 提交于 
      ipwireless (added by 099dc4fb) is clearly
a net device:

drivers/built-in.o: In function `ipwireless_ppp_start_xmit':
/home/pmundt/devel/git/sh-2.6.25/drivers/char/pcmcia/ipwireless/network.c:165: undefined reference to `skb_under_panic'
/home/pmundt/devel/git/sh-2.6.25/drivers/char/pcmcia/ipwireless/network.c:165: undefined reference to `kfree_skb'

/home/pmundt/devel/git/sh-2.6.25/drivers/char/pcmcia/ipwireless/network.c:377: undefined reference to `__alloc_skb'
/home/pmundt/devel/git/sh-2.6.25/drivers/char/pcmcia/ipwireless/network.c:377: undefined reference to `skb_over_panic'
drivers/built-in.o: In function `ppp_shutdown_interface':
/home/pmundt/devel/git/sh-2.6.25/drivers/net/ppp_generic.c:2517: undefined reference to `unregister_netdev'
/home/pmundt/devel/git/sh-2.6.25/drivers/net/ppp_generic.c:2517: undefined reference to `free_netdev'
[ ... and many more ... ]

select strikes again. ipwireless selects PPP which in turn tries to select
SLHC, both of which are technically "protected" by an if NETDEVICES
in drivers/net/Kconfig. This leads to .config hilarity, with net suddenly
ending up in the SCSI menu:

	#
	# SCSI device support
	#
	# CONFIG_SCSI_DMA is not set
	# CONFIG_SCSI_NETLINK is not set
	CONFIG_PPP=y
	# CONFIG_PHONE is not set

Curiously the SLHC select from PPP doesn't seem to happen, as there's no
CONFIG_SLHC=y (only CONFIG_PPP=y gets set) -- Kconfig bug? Caught with a
randconfig.

      Smack: check for 'struct socket' with NULL sk · 2e1d146a
      由 Ahmed S. Darwish 提交于 
      There's a small problem with smack and NFS. A similar report was also
sent here: http://lkml.org/lkml/2007/10/27/85

I've also added similar checks in inode_{get/set}security().  Cheating from
SELinux post_create_socket(), it does the same.
