wanxl: fix info leak in ioctl

2013-11-04T12:23:41+00:00

[ Upstream commit 2b13d06c9584b4eb773f1e80bbaedab9a1c344e1 ]

The wanxl_ioctl() code fails to initialize the two padding bytes of
struct sync_serial_settings after the ->loopback member. Add an explicit
memset(0) before filling the structure to avoid the info leak.

dlci: validate the net device in dlci_del()

2013-07-03T17:59:04+00:00

commit 578a1310f2592ba90c5674bca21c1dbd1adf3f0a upstream.

We triggered an oops while running trinity with 3.4 kernel:

It's because the net device is not a dlci device.

ixp4xx_hss: fix build failure due to missing linux/module.h inclusion

2012-10-12T20:38:42+00:00

[ Upstream commit 0b836ddde177bdd5790ade83772860940bd481ea ]

Commit 36a1211970193ce215de50ed1e4e1272bc814df1 (netprio_cgroup.h:
dont include module.h from other includes) made the following build
error on ixp4xx_hss pop up:

  CC [M]  drivers/net/wan/ixp4xx_hss.o
 drivers/net/wan/ixp4xx_hss.c:1412:20: error: expected ';', ',' or ')'
 before string constant
 drivers/net/wan/ixp4xx_hss.c:1413:25: error: expected ';', ',' or ')'

 make[8]: *** [drivers/net/wan/ixp4xx_hss.o] Error 1

This was previously hidden because ixp4xx_hss includes linux/hdlc.h which
includes linux/netdevice.h which includes linux/netprio_cgroup.h which
used to include linux/module.h. The real issue was actually present since
the initial commit that added this driver since it uses macros from
linux/module.h without including this file.

Documentation: remove references to /etc/modprobe.conf

2012-03-30T23:03:15+00:00

Usage of /etc/modprobe.conf file was deprecated by module-init-tools and
is no longer parsed by new kmod tool. References to this file are
replaced in Documentation, comments and Kconfig according to the
context.

There are also some references to the old /etc/modules.conf from 2.4
kernels that are being removed.

NET: pc300, show version info from module init

2012-03-08T19:47:01+00:00

Again, no need to do that from the pci probe function.

Hmm, I noticed this driver is marked as BROKEN. Won't touch it more,
it has to be converted to dynamic tty driver allocation first.

Perhaps it is time to move it to staging?
