driver core: handle user namespaces properly with the uid/gid devtmpfs change

2013-04-11T18:43:29Z

Now that devtmpfs is caring about uid/gid, we need to use the correct internal types so users who have USER_NS enabled will have things work properly for them. Thanks to Eric for pointing this out, and the patch review. Reported-by: Eric W. Biederman Cc: Kay Sievers Cc: Ming Lei Signed-off-by: Greg Kroah-Hartman

driver core: devtmpfs: fix compile failure with CONFIG_UIDGID_STRICT_TYPE_CHECKS

2013-04-10T16:36:06Z

If CONFIG_UIDGID_STRICT_TYPE_CHECKS is enalbed, the below compile failure will be triggered: drivers/base/devtmpfs.c: In function 'handle_create': drivers/base/devtmpfs.c:214:19: error: incompatible types when assigning to type 'kuid_t' from type 'uid_t' drivers/base/devtmpfs.c:215:19: error: incompatible types when assigning to type 'kgid_t' from type 'gid_t' make[2]: *** [drivers/base/devtmpfs.o] Error 1 This patch fixes the compile failure.

devtmpfs: add base.h include

2013-04-10T16:00:15Z

This fixes a sparse warning, and is a good idea given that the devtmpfs_init() prototype is in this file. Signed-off-by: Greg Kroah-Hartman

driver core: add uid and gid to devtmpfs

2013-04-08T15:21:48Z

Some drivers want to tell userspace what uid and gid should be used for their device nodes, so allow that information to percolate through the driver core to userspace in order to make this happen. This means that some systems (i.e. Android and friends) will not need to even run a udev-like daemon for their device node manager and can just rely in devtmpfs fully, reducing their footprint even more.

Where we can pass in LOOKUP_DIRECTORY or LOOKUP_REVAL. Any other flags passed in here are currently ignored. Signed-off-by: Jeff Layton Signed-off-by: Al Viro

get rid of kern_path_parent()

2012-07-14T12:35:02Z

all callers want the same thing, actually - a kinda-sorta analog of kern_path_create(). I.e. they want parent vfsmount/dentry (with ->i_mutex held, to make sure the child dentry is still their child) + the child dentry. Signed-off-by Al Viro
