2011-03-14untangle the "need_reval_dot" messAl Viro
instead of ad-hackery around need_reval_dot(), do the following: set a flag (LOOKUP_JUMPED) in the beginning of path, on absolute symlink traversal, on ".." and on procfs-style symlinks. Clear on normal components, leave unchanged on ".". Non-nested callers of link_path_walk() call handle_reval_path(), which checks that flag is set and that fs does want the final revalidate thing, then does ->d_revalidate(). In link_path_walk() all the return_reval stuff is gone. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2011-03-14merge path_init and path_init_rcuAl Viro
Actual dependency on whether we want RCU or not is in 3 small areas (as it ought to be) and everything around those is the same in both versions. Since each function has only one caller and those callers are on two sides of if (flags & LOOKUP_RCU), it's easier and cleaner to merge them and pull the checks inside.

2011-03-14sanitize path_walk() messAl Viro
New helper: path_lookupat(). Basically, what do_path_lookup() boils to modulo -ECHILD/-ESTALE handler. path_walk* family is gone; vfs_path_lookup() is using link_path_walk() directly, do_path_lookup() and do_filp_open() are using path_lookupat(). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2011-03-13compat breakage in preadv() and pwritev()Al Viro
Fix for a dumb preadv()/pwritev() compat bug - unlike the native variants, compat_... ones forget to check FMODE_P{READ,WRITE}, so e.g. on pipe the native preadv() will fail with -ESPIPE and compat one will act as readv() and succeed. Not critical, but it's a clear bug with trivial fix. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2011-03-10drm/i915: Revive combination mode for backlight controlTakashi Iwai
This reverts commit 951f3512dba5bd44cda3e5ee22b4b522e4bb09fb drm/i915: Do not handle backlight combination mode specially since this commit introduced other regressions due to untouched LBPC register, e.g. the backlight dimmed after resume. In addition to the revert, this patch includes a fix for the original issue (weird backlight levels) by removing the wrong bit shift for computing the current backlight level. Also, including typo fixes (lpbc -> lbpc).

2011-03-10fs/dcache: allow d_obtain_alias() to return unhashed dentriesJ. Bruce Fields
Without this patch, inodes are not promptly freed on last close of an unlinked file by an nfs client: client$ mount -tnfs4 server:/export/ /mnt/ client$ tail -f /mnt/FOO ... server$ df -i /export server$ rm /export/FOO (^C the tail -f) server$ df -i /export server$ echo 2 >/proc/sys/vm/drop_caches server$ df -i /export the df's will show that the inode is not freed on the filesystem until the last step, when it could have been freed after killing the client's tail -f. On-disk data won't be deallocated either, leading to possible spurious ENOSPC. This occurs because when the client does the close, it arrives in a compound with a putfh and a close, processed like: - putfh: look up the filehandle.  The only alias found for the inode will be DCACHE_UNHASHED alias referenced by the filp this, so it creates a new DCACHE_DISCONECTED dentry and returns that instead. - close: closes the existing filp, which is destroyed immediately by dput() since it's DCACHE_UNHASHED. - end of the compound: release the reference to the current filehandle, and dput() the new DCACHE_DISCONECTED dentry, which gets put on the unused list instead of being destroyed immediately. Nick Piggin suggested fixing this by allowing d_obtain_alias to return the unhashed dentry that is referenced by the filp, instead of making it create a new dentry. Leave __d_find_alias() alone to avoid changing behavior of other callers. Also nfsd doesn't need all the checks of __d_find_alias(); any dentry, hashed or unhashed, disconnected or not, should work.

2011-03-10Check for immutable/append flag in fallocate pathMarco Stornelli
In the fallocate path the kernel doesn't check for the immutable/append flag. It's possible to have a race condition in this scenario: an application open a file in read/write and it does something, meanwhile root set the immutable flag on the file, the application at that point can call fallocate with success. In addition, we don't allow to do any unreserve operation on an append only file but only the reserve one.

2011-03-09net: don't allow CAP_NET_ADMIN to load non-netdev kernel modulesVasiliy Kulikov
Since a8f80e8ff94ecba629542d9b4b5f5a8ee3eb565c any process with CAP_NET_ADMIN may load any module from /lib/modules/. This doesn't mean that CAP_NET_ADMIN is a superset of CAP_SYS_MODULE as modules are limited to /lib/modules/**. However, CAP_NET_ADMIN capability shouldn't allow anybody load any module not related to networking. This patch restricts an ability of autoloading modules to netdev modules with explicit aliases. This fixes CVE-2011-1019. Arnd Bergmann suggested to leave untouched the old pre-v2.6.32 behavior of loading netdev modules by name (without any prefix) for processes with CAP_SYS_MODULE to maintain the compatibility with network scripts that use autoloading netdev modules by aliases like "eth0", "wlan0".

2011-03-09powerpc/iseries: Fix early init access to lppacaBenjamin Herrenschmidt
The combination of commit 8154c5d22d91cd16bd9985b0638c8957e4688d0e and 93c22703efa72c7527dbd586d1951c1f4a85fd70 Broke boot on iSeries. The problem is that iSeries very early boot code, which generates the device-tree and runs before our normal early initializations does need access the lppaca's very early, before the PACA array is initialized, and in fact even before the boot PACA has been initialized (it contains all 0's at this stage). However, the first patch above makes that code use the new llpaca_of(cpu) accessor, which itself is changed by the second patch to use the PACA array. We fix that by reverting iSeries to directly dereferencing the array. In addition, we fix all iterators in the iSeries code to always skip CPU whose number is above 63 which is the maximum size of that array and the maximum number of supported CPUs on these machines. Additionally, we make sure the boot_paca is properly initialized in our early startup code. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

kallsyms has a virtual file name [kernel.kallsyms]. Currently, it can't be added to buildid cache successfully because the code (build_id_cache__add_s) tries to resolve [kernel.kallsyms] to a real absolute pathname and that fails. Fixes it by not resolving it and just use the name [kernel.kallsyms]. So dir ~/.debug/[kernel.kallsyms] is created.
