2011-01-24Make CIFS mount work in a container.Rob Landley2-2/+43
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 Russell4-4/+6

2011-01-24BUILD_BUG_ON: make it handle more casesRusty Russell1-6/+27
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 <[email protected]> Cc: Jan Beulich <[email protected]> Acked-by: Hollis Blanchard <[email protected]>

2011-01-24module: show version information for built-in modules in sysfsDmitry Torokhov3-11/+88
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 Juhl1-1/+0
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 Wilson3-4/+10
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.

2011-01-22m68k: Uninline strchr()Geert Uytterhoeven1-12/+0
Some versions of gcc replace calls to strstr() with single-character "needle" string parameters by calls to strchr() behind our back. If strchr() is defined as an inline function, this causes linking errors like ERROR: "strchr" [drivers/target/target_core_mod.ko] undefined! As m68k is the only architecture that has an inline strchr() and this inline version is not an optimized asm version, uninline strchr() and use the standard out-of-line C version in lib/string.c instead.

2011-01-21x86, hotplug: Fix powersavings with offlined cores on AMDBorislav Petkov3-2/+5
ea53069231f9317062910d6e772cca4ce93de8c8 made a CPU use monitor/mwait when offline. This is not the optimal choice for AMD wrt to powersavings and we'd prefer our cores to halt (i.e. enter C1) instead. For this, the same selection whether to use monitor/mwait has to be used as when we select the idle routine for the machine. With this patch, offlining cores 1-5 on a X6 machine allows core0 to boost again.

2011-01-21drivers: mmc: msm: remove clock disable in probeDaniel Walker1-3/+0
The probe function adds the MMC host which can start accepting request immediately. There is an assumption here that no requests happen immediatly, but it's not always the case. This assumption can causes a BUG() when the clocks are disabled. The fix is to just remove the clock disable in the probe function. Signed-off-by: Daniel Walker <[email protected]>
