Allow mount to do authenticated mounts below the root of the exported tree. The wording in RFC 2623, sec 2.3.2. allows fsinfo with UNIX authentication on the root of the export. Mounts are not always done on the root of the exported tree. Especially autoumounts often mount below the root of the exported tree. Some server implementations (justly) require full authentication for the so-called deep mounts. The old code used AUTH_SYS only. This caused deep mounts to fail on systems requiring stronger authentication.. The client should try both authentication types and use the first one that succeeds. This method was already partially implemented. This patch completes the implementation for NFS2 and NFS3. This patch was developed to allow Debian systems to automount home directories on Solaris servers with krb5 authentication. Tested on kernel 2.6.24-etchnhalf.1 Signed-off-by: NE.G.

In the case where there are parallel RPC calls to the same inode, we may receive stale metadata due to the lack of ordering, hence the sanity checking of metadata in nfs_refresh_inode(). Currently, __nfs_revalidate_inode() is calling nfs_update_inode() directly, without any further sanity checks, and hence may end up setting the inode up with stale metadata. Fix is to use nfs_refresh_inode() instead of nfs_update_inode(). Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

If we believe that the attributes are old (see nfs_refresh_inode()), then we shouldn't force an update.

Currently nfs_refresh_inode() will only update the inode metadata if it sees that the RPC call that returned the nfs_fattr was started after the last update of the inode. This means that if we have parallel RPC calls to the same inode (when sending WRITE calls, for instance), we may often miss updates. This patch attempts to recover those missed updates by also accepting them if the ctime in the nfs_fattr is more recent than the inode's cached ctime. It also recovers the case where the file size has increased, but the ctime has not been updated due to limited ctime resolution. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

The previous patch db203d53 ("mm: tiny-shmem fix lock ordering: mmap_sem vs i_mutex") to fix the lock ordering in tiny-shmem breaks shared anonymous and IPC memory on NOMMU architectures because it was using the expanding truncate to signal ramfs to allocate a physically contiguous RAM backing the inode (otherwise it is unusable for "memory mapping" it to userspace). However do_truncate is what caused the lock ordering error, due to it taking i_mutex. In this case, we can actually just call ramfs directly to allocate memory for the mapping, rather than go via truncate.

There's a race between mm->owner assignment and swapoff, more easily seen when task slab poisoning is turned on. The condition occurs when try_to_unuse() runs in parallel with an exiting task. A similar race can occur with callers of get_task_mm(), such as /proc/<pid>/<mmstats> or ptrace or page migration. CPU0 CPU1 try_to_unuse looks at mm = task0->mm increments mm->mm_users task 0 exits mm->owner needs to be updated, but no new owner is found (mm_users > 1, but no other task has task->mm = task0->mm) mm_update_next_owner() leaves mmput(mm) decrements mm->mm_users task0 freed dereferencing mm->owner fails The fix is to notify the subsystem via mm_owner_changed callback(), if no new owner is found, by specifying the new task as NULL. Jiri Slaby: mm->owner was set to NULL prior to calling cgroup_mm_owner_callbacks(), but must be set after that, so as not to pass NULL as old owner causing oops. Daisuke Nishimura: mm_update_next_owner() may set mm->owner to NULL, but mem_cgroup_from_task() and its callers need to take account of this situation to avoid oops. Hugh Dickins: Lockdep warning and hang below exec_mmap() when testing these patches. exit_mm() up_reads mmap_sem before calling mm_update_next_owner(), so exec_mmap() now needs to do the same. And with that repositioning, there's now no point in mm_need_new_owner() allowing for NULL mm.

由 Linus Torvalds 提交于
The VFS interface for the 'd_compare()' is a bit special (read: 'odd'), because it really just essentially replaces a memcmp(). The filesystem is supposed to just compare the two names with whatever case-independent or other function. And when I say 'is supposed to', I obviously mean that 'procfs does odd things, and actually looks at the dentry that we don't even pass down, rather than just the name'. Which results in problems, because we actually call d_compare before we have even verified that the dentry is still hashed at all. And that causes a problm since the inode that procfs looks at may have been free'd and the d_inode pointer is NULL. procfs just assumes that all dentries are positive, since procfs itself never generates a negative one. But memory pressure will still result in the dentry getting torn down, and as it is removed by RCU, it still remains visible on some lists - and to d_compare. If the filesystem just did a name comparison, we wouldn't care. And we could just fix procfs to know about negative dentries too. But rather than have the low-level filesystems know about internal VFS details, just move the check for a unhashed dentry up a bit, so that we will only call d_compare on dentries that are still active. The actual oops this caused didn't look like a NULL pointer dereference because procfs did a 'container_of(inode, struct proc_inode, vfs_inode)' to get at its internal proc_inode information from the inode pointer, and accessed a field below the inode. So the oops would look something like BUG: unable to handle kernel paging request at fffffffffffffff0 IP: [<ffffffff802bc6c6>] proc_sys_compare+0x36/0x50 and was seen on both x86-64 (Alexey Dobriyan and Hugh Dickins) and ppc64 (Hugh Dickins).

Yet another bug was found in xfs_iext_irec_compact_full() and while the source of the bug was found it wasn't an easy task to track it down because the conditions are very difficult to reproduce. A HUGE thank-you goes to Russell Cattelan and Eric Sandeen for their significant effort in tracking down the source of this corruption. xfs_iext_irec_compact_full() and xfs_iext_irec_compact_pages() are almost identical - they both compact indirect extent lists by moving extents from subsequent buffers into earlier ones. xfs_iext_irec_compact_pages() only moves extents if all of the extents in the next buffer will fit into the empty space in the buffer before it. xfs_iext_irec_compact_full() will go a step further and move part of the next buffer if all the extents wont fit. It will then shift the remaining extents in the next buffer up to the start of the buffer. The bug here was that we did not update er_extoff and this caused extent list corruption. It does not appear that this extra functionality gains us much. Calling xfs_iext_irec_compact_pages() instead will do a good enough job at compacting the indirect list and will be quicker too. For the case in xfs_iext_indirect_to_direct() the total number of extents in the indirect list will fit into one buffer so we will never need the extra functionality of xfs_iext_irec_compact_full() there. Also xfs_iext_irec_compact_pages() doesn't need to do a memmove() (the buffers will never overlap) so we don't want the performance hit that can incur.

When unreserving space with boundaries that are not block aligned we round up the start and round down the end boundaries and then use this function, xfs_zero_remaining_bytes(), to zero the parts of the blocks that got dropped during the rounding. The problem is we don't consider if these blocks are beyond eof. Worse still is if we encounter delayed allocations beyond eof we will try to use the magic delayed allocation block number as a real block number. If the file size is ever extended to expose these blocks then we'll go through xfs_zero_eof() to zero them anyway.

If we call xfs_lock_two_inodes() to grab both the iolock and the ilock, then drop the ilocks on both inodes, then grab them again (as xfs_swap_extents() does) then lockdep will report a locking order problem. This is a false positive. To avoid this, disallow xfs_lock_two_inodes() fom locking both inode locks at once - force calers to make two separate calls. This means that nested dropping and regaining of the ilocks will retain the same lockdep subclass and so lockdep will not see anything wrong with this code.

With the help from some tracing I found that we try to map extents beyond eof when doing a direct I/O read. It appears that the way to inform the generic direct I/O path (ie do_direct_IO()) that we have breached eof is to return an unmapped buffer from xfs_get_blocks_direct(). This will cause do_direct_IO() to jump to the hole handling code where is will check for eof and then abort. This problem was found because a direct I/O read was trying to map beyond eof and was encountering delayed allocations. The delayed allocations beyond eof are speculative allocations and they didn't get converted when the direct I/O flushed the file because there was only enough space in the current AG to convert and write out the dirty pages within eof. Note that xfs_iomap_write_allocate() wont necessarily convert all the delayed allocation passed to it - it will return after allocating the first extent - so if the delayed allocation extends beyond eof then it will stay that way.

Logically we would return an error in xfs_fs_remount code to prevent users from believing they might have changed mount options using remount which can't be changed. But unfortunately mount(8) adds all options from mtab and fstab to the mount arguments in some cases so we can't blindly reject options, but have to check for each specified option if it actually differs from the currently set option and only reject it if that's the case. Until that is implemented we return success for every remount request, and silently ignore all options that we can't actually change.

Memory allocations for log->l_grant_trace and iclog->ic_trace are done on demand when the first event is logged. In xlog_state_get_iclog_space() we call xlog_trace_iclog() under a spinlock and allocating memory here can cause us to sleep with a spinlock held and deadlock the system. For the log grant tracing we use KM_NOSLEEP but that means we can lose trace entries. Since there is no locking to serialize the log grant tracing we could race and have multiple allocations and leak memory. So move the allocations to where we initialize the log/iclog structures. Use KM_NOFS to avoid recursing into the filesystem and drop log->l_trace since it's not even used.
