2011-01-24Make CIFS mount work in a container.Rob Landley
Teach cifs about network namespaces, so mounting uses adresses/routing visible from the container rather than from init context. A container is a chroot on steroids that changes more than just the root filesystem the new processes see. One thing containers can isolate is "network namespaces", meaning each container can have its own set of ethernet interfaces, each with its own own IP address and routing to the outside world. And if you open a socket in _userspace_ from processes within such a container, this works fine. But sockets opened from within the kernel still use a single global networking context in a lot of places, meaning the new socket's address and routing are correct for PID 1 on the host, but are _not_ what userspace processes in the container get to use. So when you mount a network filesystem from within in a container, the mount code in the CIFS driver uses the host's networking context and not the container's networking context, so it gets the wrong address, uses the wrong routing, and may even try to go out an interface that the container can't even access... Bad stuff. This patch copies the mount process's network context into the CIFS structure that stores the rest of the server information for that mount point, and changes the socket open code to use the saved network context instead of the global network context. I.E. "when you attempt to use these addresses, do so relative to THIS set of network interfaces and routing rules, not the old global context from back before we supported containers". The big long HOWTO sets up a test environment on the assumption you've never used ocntainers before. It basically says: 1) configure and build a new kernel that has container support 2) build a new root filesystem that includes the userspace container control package (LXC) 3) package/run them under KVM (so you don't have to mess up your host system in order to play with containers). 4) set up some containers under the KVM system 5) set up contradictory routing in the KVM system and the container so that the host and the container see different things for the same address 6) try to mount a CIFS share from both contexts so you can both force it to work and force it to fail.

2011-01-24Remove MAYBE_BUILD_BUG_ONRusty Russell

2011-01-24BUILD_BUG_ON: make it handle more casesRusty Russell
BUILD_BUG_ON used to use the optimizer to do code elimination or fail at link time; it was changed to first the size of a negative array (a nicer compile time error), then (in 8c87df457cb58fe75b9b893007917cf8095660a0) to a bitfield. This forced us to change some non-constant cases to MAYBE_BUILD_BUG_ON(); as Jan points out in that commit, it didn't work as intended anyway. bitfields: needs a literal constant at parse time, and can't be put under "if (__builtin_constant_p(x))" for example. negative array: can handle anything, but if the compiler can't tell it's a constant, silently has no effect. link time: breaks link if the compiler can't determine the value, but the linker output is not usually as informative as a compiler error. If we use the negative-array-size method *and* the link time trick, we get the ability to use BUILD_BUG_ON() under __builtin_constant_p() branches, and maximal ability for the compiler to detect errors at build time. We also document it thoroughly. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Cc: Jan Beulich <JBeulich@novell.com> Acked-by: Hollis Blanchard <hollisb@us.ibm.com>

2011-01-24module: show version information for built-in modules in sysfsDmitry Torokhov
Currently only drivers that are built as modules have their versions shown in /sys/module/<module_name>/version, but this information might also be useful for built-in drivers as well. This especially important for drivers that do not define any parameters - such drivers, if built-in, are completely invisible from userspace. This patch changes MODULE_VERSION() macro so that in case when we are compiling built-in module, version information is stored in a separate section. Kernel then uses this data to create 'version' sysfs attribute in the same fashion it creates attributes for module parameters.

2011-01-24CIFS: Remove pointless variable assignment in cifs_dfs_do_automount()Jesper Juhl
In fs/cifs/cifs_dfs_ref.c::cifs_dfs_do_automount() we have this code: ... mnt = ERR_PTR(-EINVAL); if (IS_ERR(tlink)) { mnt = ERR_CAST(tlink); goto free_full_path; } ses = tlink_tcon(tlink)->ses; rc = get_dfs_path(xid, ses, full_path + 1, cifs_sb->local_nls, &num_referrals, &referrals, cifs_sb->mnt_cifs_flags & CIFS_MOUNT_MAP_SPECIAL_CHR); cifs_put_tlink(tlink); mnt = ERR_PTR(-ENOENT); ... The assignment of 'mnt = ERR_PTR(-EINVAL);' is completely pointless. If we take the 'if (IS_ERR(tlink))' branch we'll set 'mnt' again and we'll also do so if we do not take the branch. There is no way we'll ever use 'mnt' with the assigned 'ERR_PTR(-EINVAL)' value, so we may as well just remove the pointless assignment.

2011-01-23drm/i915: Recognise non-VGA display devicesChris Wilson
Starting with SandyBridge (though possible with earlier hacked BIOSes), the BIOS may initialise the IGFX as secondary to a discrete GPU. Prior, it would simply disable the integrated GPU. So we adjust our PCI class mask to match any DISPLAY_CLASS device. In such a configuration, the IGFX is not a primary VGA controller and so should not take part in VGA arbitration, and the error return from vga_client_register() is expected.

2011-01-22n_hdlc: fix read and write lockingPaul Fulghum
Fix locking in read and write code of n_hdlc line discipline. 2.6.36 replaced lock_kernel() with tty_lock(). The tty mutex is not dropped automatically when the thread sleeps like the BKL. This results in a blocked read or write holding the tty mutex and stalling operations by other devices that use the tty mutex. A review of n_hdlc read and write code shows: 1. neither BKL or tty mutex are required for correct operation 2. read can block while read data is available if data is posted between availability check and call to interruptible_sleep_on() 3. write does not set process state to TASK_INTERRUPTIBLE on each pass through the processing loop which can cause unneeded scheduling of the thread The unnecessary tty mutex references have been removed. Read changed to use same code as n_tty read for completing reads and blocking. Write corrected to set process state to TASK_INTERRUPTIBLE on each pass through processing loop.

2011-01-22USB: gadget: Fix endpoint representation in ci13xxx_udcPavankumar Kondeti
Fix a bug where only half the number of endpoints supported by the hardware are exposed to gadget. If DEN filed in the DCCPARAMS register has 'N' then 'N' IN endpoints and 'N" OUT endpoints can be supported. But only 'N' bidirectional endpoints are added to the gadget ep_list. This patch also ensures that the data and handshake transactions of previous setup packet are flushed upon a new setup packet arrival on ep0.

2011-01-22USB: gadget: Fix error path in ci13xxx_udc gadget probe functionPavankumar Kondeti
Don't call gadget driver's unbind when bind is failed. Initialize udc->driver only after gadget driver bind is successful. Otherwise pull-up can be enabled upon VBUS session even when no gadget is bounded. Signed-off-by: Pavankumar Kondeti <pkondeti@codeaurora.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2011-01-22USB: serial: Updated support for ICOM devicesPieter Maes
I found the original patch on the db0fhn repeater wiki (couldn't find the email of the origial author) I guess it was never commited. I updated and added some Icom HAM-radio devices to the ftdi driver. Added extra comments to make clear what devices it are.
