Message-ID: <15909.1239887985@jrobl> (raw)
I have found (at least) two issues about IMA.
1.
Calling stack
- kmem_cache_alloc(iint_cache, GFP_KERNEL)
- ima_inode_alloc()
- inode_init_always()
- xfs_iget_cache_hit()
- xfs_iget()
xfs_iget() holds spinlock before xfs_iget_cache_hit(), and
ima_inode_alloc() cannot use GFP_KERNEL.
2.
ima_path_check() seems to be necessary before every opening a file.
In 2.6.30-rc1, IMA produces lots of messages and stack trace when NFSD
opens a file.
Does nfsd_open() need to to call ima_path_check()?
