2009-09-01lsm: Add hooks to the TUN driverPaul Moore1-7/+15
The TUN driver lacks any LSM hooks which makes it difficult for LSM modules, such as SELinux, to enforce access controls on network traffic generated by TUN users; this is particularly problematic for virtualization apps such as QEMU and KVM. This patch adds three new LSM hooks designed to control the creation and attachment of TUN devices, the hooks are: * security_tun_dev_create() Provides access control for the creation of new TUN devices * security_tun_dev_post_create() Provides the ability to create the necessary socket LSM state for newly created TUN devices * security_tun_dev_attach() Provides access control for attaching to existing, persistent TUN devices and the ability to update the TUN device's socket LSM state as necessary Signed-off-by: Paul Moore <paul.moore@hp.com> Acked-by: Eric Paris <eparis@parisplace.org> Acked-by: Serge Hallyn <serue@us.ibm.com> Acked-by: David S.

2009-08-14drivers/net: fixed drivers that support netpoll use ndo_start_xmit()Dongdong Deng4-8/+12
The NETPOLL API requires that interrupts remain disabled in netpoll_send_skb(). The use of spin_lock_irq() and spin_unlock_irq() in the NETPOLL API callbacks causes the interrupts to get enabled and can lead to kernel instability. The solution is to use spin_lock_irqsave() and spin_unlock_restore() to prevent the irqs from getting enabled while in netpoll_send_skb().

2009-08-13ixgbe: Do not return 0 in ixgbe_fcoe_ddp() upon FCP_RSP in DDP completionYi Zou1-1/+1
We return the ddp->len in ixgbe_fcoe_ddp() to indicate the length of data that have been DDPed. However, it is possible that the length is 0, e.g., for SCSI READ, the FCP_RSP may come back w/ SCSI status 0x28 as Task Set Full with no FCP data for DDP. In ixgbe_fcoe_ddp(), we return 0 to indicate not passing DDPed packets to upper layer. Therefore in the case of ddp->len being 0 upon FCP_RSP, we do not want to return the 0 ddp->len as we want FCP_RSP to be always delivered to the upper layer. This patch fixes this bug by setting rc only if ddp->len is non-zero.

2009-08-14Networking: use CAP_NET_ADMIN when deciding to call request_moduleEric Paris1-4/+4
The networking code checks CAP_SYS_MODULE before using request_module() to try to load a kernel module. While this seems reasonable it's actually weakening system security since we have to allow CAP_SYS_MODULE for things like /sbin/ip and bluetoothd which need to be able to trigger module loads. CAP_SYS_MODULE actually grants those binaries the ability to directly load any code into the kernel. We should instead be protecting modprobe and the modules on disk, rather than granting random programs the ability to load code directly into the kernel. Instead we are going to gate those networking checks on CAP_NET_ADMIN which still limits them to root but which does not grant those processes the ability to load arbitrary code into the kernel.

2009-08-13V4L/DVB (12440): Use kzalloc for frontend states to have struct dvb_frontend ↵Matthias Schwarzott25-28/+28
properly This patch changes most frontend drivers to allocate their state structure via kzalloc and not kmalloc. This is done to properly initialize the embedded "struct dvb_frontend frontend" field, that they all have. The visible effect of this struct being uninitalized is, that the member "id" that is used to set the name of kernel thread is totally random. Some board drivers (for example cx88-dvb) set this "id" via videobuf_dvb_alloc_frontend but most do not. So I at least get random id values for saa7134, flexcop and ttpci based cards. It looks like this in dmesg: DVB: registering adapter 1 frontend -10551321 (ST STV0299 DVB-S) The related kernel thread then also gets a strange name like "kdvb-ad-1-fe--1".

2009-08-13V4L/DVB (12429): v4l2-ioctl: fix G_STD and G_PARM default handlersHans Verkuil1-3/+12
The v4l core supplies default handlers for G_STD and G_PARM. However, both default handlers are buggy. This patch fixes the following: 1) If no g_std is supplied and current_norm == 0, then this driver does not support TV video standards (e.g. a radio or webcam driver). Return -EINVAL. This ensures that there is no bogus VIDIOC_G_STD support for such drivers. 2) The default VIDIOC_G_PARM handler used current_norm instead of first checking if the driver supported g_std and calling that to get the norm. It also didn't check if current_norm was 0, since in that case the driver does not support TV standards (or no standard was set at all) and the default handler should return -EINVAL. Note that I am very unhappy with these default handlers: I think they basically behave like some very strange and unexpected side-effect.

2009-08-13V4L/DVB (12405): em28xx-cards: move register 0x13 setting to the proper placeMauro Carvalho Chehab2-4/+3
Register 0x13 seems to be a sort of image control, maybe gamma, white level or black level. Lower values produce better images, while higher values increases the contrast and shifts colors to green. 0xff produces a black image. This register is not Silvercrest-specific, so its code should be moved to a better place. If this register is left alone, a random value can be found at the register, producing weird results. While here, let's remove register 0x0d, as it had no noticed effect at the image. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
