hamradio/yam: fix info leak in ioctl

2014-01-15T23:31:36+00:00

[ Upstream commit 8e3fbf870481eb53b2d3a322d1fc395ad8b367ed ]

The yam_ioctl() code fails to initialise the cmd field
of the struct yamdrv_ioctl_cfg. Add an explicit memset(0)
before filling the structure to avoid the 4-byte info leak.

drivers/net/hamradio: Integer overflow in hdlcdrv_ioctl()

2014-01-15T23:31:36+00:00

[ Upstream commit e9db5c21d3646a6454fcd04938dd215ac3ab620a ]

The local variable 'bi' comes from userspace. If userspace passed a
large number to 'bi.data.calibrate', there would be an integer overflow
in the following line:
	s->hdlctx.calibrate = bi.data.calibrate * s->par.bitrate / 16;

net: pass info struct via netdevice notifier

2013-05-28T20:11:01+00:00

So far, only net_device * could be passed along with netdevice notifier
event. This patch provides a possibility to pass custom structure
able to provide info that event listener needs to know.

drivers/net: rename random32() to prandom_u32()

2013-05-08T01:38:27+00:00

Use preferable function name which implies using a pseudo-random number
generator.

yam: remove redundant null check on dev

2013-03-27T18:30:55+00:00

yam_open has a redundant null check on null,  it will
never be called with dev == NULL. Remove this redundant check.
This also cleans up a smatch warning:

drivers/net/hamradio/yam.c:869 yam_open() warn: variable
  dereferenced before check 'dev' (see line 867)

net: proc: change proc_net_remove to remove_proc_entry

2013-02-18T19:53:08+00:00

proc_net_remove is only used to remove proc entries
that under /proc/net,it's not a general function for
removing proc entries of netns. if we want to remove
some proc entries which under /proc/net/stat/, we still
need to call remove_proc_entry.

this patch use remove_proc_entry to replace proc_net_remove.
we can remove proc_net_remove after this patch.

net: proc: change proc_net_fops_create to proc_create

2013-02-18T19:53:08+00:00

Right now, some modules such as bonding use proc_create
to create proc entries under /proc/net/, and other modules
such as ipv4 use proc_net_fops_create.

It looks a little chaos.this patch changes all of
proc_net_fops_create to proc_create. we can remove
proc_net_fops_create after this patch.
