| |
Linus,
Please pull the userns-linus branch from the git tree:
git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git userns-linus
HEAD: 82c9a927bc5df6e06b72d206d24a9d10cced4eb5 getxattr: use correct xattr length
This is a set of 4 fairly obvious bug fixes. A switch from d_find_alias to d_find_any_alias because the xattr code perversely takes a dentry. Two mutex vs copy_to_user fixes from Jann Horn and a fix to use a sanitized size not the size userspace passed in from Christian Brauner.
This is coming late because I fell behind this last development cycle, and because I have been travelling. I do not intend to make a habit of sending pull requests late.
The last fix by Christian Brauner has a very recent commit date. I was doing a final review of this pull request and I noticed it was mixing a fixes tag. I added the fixes tag so that the bug that is being fixed can be put into perspective.
Resent because I somehow missed the [GIT PULL] tag when I sent this out the first time. I think travelling from GMT-0500 to GMT+0200 to visit family is affecting more than I thought.
Christian Brauner (1): getxattr: use correct xattr length
Eddie.Horng (1): cap_inode_getsecurity: use d_find_any_alias() instead of d_find_alias()
Jann Horn (2): userns: move user access out of the mutex sys: don't hold uts_sem while accessing userspace memory
