xfs: fix dir3 freespace block corruption
When the directory freespace index grows to a second block (2017
4k data blocks in the directory), the initialisation of the second
new block header goes wrong. The write verifier fires a corruption
error indicating that the block number in the header is zero. This
was being tripped by xfs/110.
The problem is that the initialisation of the new block is done just
fine in xfs_dir3_free_get_buf(), but the caller then users a dirv2
structure to zero on-disk header fields that xfs_dir3_free_get_buf()
has already zeroed. These lined up with the block number in the dir
v3 header format.
While looking at this, I noticed that the struct xfs_dir3_free_hdr()
had 4 bytes of padding in it that wasn't defined as padding or being
zeroed by the initialisation. Add a pad field declaration and fully
zero the on disk and in-core headers in xfs_dir3_free_get_buf() so
that this is never an issue in the future. Note that this doesn't
change the on-disk layout, just makes the 32 bits of padding in the
layout explicit.

xfs: disable swap extents ioctl on CRC enabled filesystems
Currently, swapping extents from one inode to another is a simple
act of switching data and attribute forks from one inode to another.
This, unfortunately in no longer so simple with CRC enabled
filesystems as there is owner information embedded into the BMBT
blocks that are swapped between inodes. Hence swapping the forks
between inodes results in the inodes having mapping blocks that
point to the wrong owner and hence are considered corrupt.
To fix this we need an extent tree block or record based swap
algorithm so that the BMBT block owner information can be updated
atomically in the swap transaction. This is a significant piece of
new work, so for the moment simply don't allow swap extent
operations to succeed on CRC enabled filesystems.

xfs: fix incorrect remote symlink block count
When CRCs are enabled, the number of blocks needed to hold a remote

into account and only allocating one block. Hence when trying to

(cherry picked from commit 321a95839e65db3759a07a3655184b0283af90fe)
That problem occurred when a contiguous dirty region of a buffer was
split across across two pages of an unmapped buffer. It's been a
long time since that has been done in XFS, and the changes to log
the entire inode buffers for CRC enabled filesystems has
re-introduced that corner case.
And, of course, it turns out that the above commit didn't actually
fix anything - it just ensured that log recovery is guaranteed to
fail when this situation occurs. And now for the gory details.
xfstest xfs/085 is failing with this assert:
XFS (vdb): bad number of regions (0) in inode log format
XFS: Assertion failed: 0, file: fs/xfs/xfs_log_recover.c, line: 1583
Largely undocumented factoid #1: Log recovery depends on all log
buffer format items starting with this format:
As recoery uses the size field and assumptions about 32 bit
alignment in decoding format items. So don't pay much attention to
the fact log recovery thinks that it decoding an inode log format
item - it just uses them to determine what the size of the item is.
But why would it see a log format item with a zero size? Well,
luckily enough xfs_logprint uses the same code and gives the same
error, so with a bit of gdb magic, it turns out that it isn't a log
format that is being decoded. What logprint tells us is this:
Oper (130): tid: a0375e1a len: 28 clientid: TRANS flags: none
BUF: #regs: 2 start blkno: 144 (0x90) len: 16 bmap size: 2 flags: 0x4000
Oper (131): tid: a0375e1a len: 4096 clientid: TRANS flags: none
BUF DATA
----------------------------------------------------------------------------
Oper (132): tid: a0375e1a len: 4096 clientid: TRANS flags: none
xfs_logprint: unknown log operation type (4e49)
**********************************************************************
* ERROR: data block=2 *
**********************************************************************
That we've got a buffer format item (oper 130) that has two regions;
the format item itself and one dirty region. The subsequent region
after the buffer format item and it's data is them what we are
tripping over, and the first bytes of it at an inode magic number.
Not a log opheader like there is supposed to be.
That means there's a problem with the buffer format item. It's dirty
data region is 4096 bytes, and it contains - you guessed it -
initialised inodes. But inode buffers are 8k, not 4k, and we log
them in their entirety. So something is wrong here. The buffer
format item contains:
Two regions, and a signle dirty contiguous region of 64 bits. 64 *
128 = 8k, so this should be followed by a single 8k region of data.
And the blf_flags tell us that the type of buffer is a
XFS_BLFT_DINO_BUF. It contains inodes. And because it doesn't have
the XFS_BLF_INODE_BUF flag set, that means it's an inode allocation
buffer. So, it should be followed by 8k of inode data.
and so be32_to_cpu(oh_len) = 0x1000 = 4096 bytes. It's simply not
long enough to hold all the logged data. There must be another
region. There is - there's a following opheader for another 4k of
data that contains the other half of the inode cluster data - the
one we assert fail on because it's not a log format header.
So why is the second part of the data not being accounted to the
correct buffer log format structure? It took a little more work with
gdb to work out that the buffer log format structure was both
expecting it to be there but hadn't accounted for it. It was at that
point I went to the kernel code, as clearly this wasn't a bug in
xfs_logprint and the kernel was writing bad stuff to the log.
First port of call was the buffer item formatting code, and the
discontiguous memory/contiguous dirty region handling code
immediately stood out. I've wondered for a long time why the code
had this comment in it:
vecp->i_addr = xfs_buf_offset(bp, buffer_offset);
vecp->i_len = nbits * XFS_BLF_CHUNK;
vecp->i_type = XLOG_REG_TYPE_BCHUNK;
/*
* You would think we need to bump the nvecs here too, but we do not
* this number is used by recovery, and it gets confused by the boundary
* split here
* nvecs++;
*/
vecp++;
And it didn't account for the extra vector pointer. The case being
handled here is that a contiguous dirty region lies across a
boundary that cannot be memcpy()d across, and so has to be split
into two separate operations for xlog_write() to perform.
What this code assumes is that what is written to the log is two
consecutive blocks of data that are accounted in the buf log format
item as the same contiguous dirty region and so will get decoded as
such by the log recovery code.
The thing is, xlog_write() knows nothing about this, and so just
does it's normal thing of adding an opheader for each vector. That
means the 8k region gets written to the log as two separate regions
of 4k each, but because nvecs has not been incremented, the buf log
format item accounts for only one of them.
Hence when we come to log recovery, we process the first 4k region
and then expect to come across a new item that starts with a log
format structure of some kind that tells us whenteh next data is
going to be. Instead, we hit raw buffer data and things go bad real
quick.
So, the commit from 2002 that commented out nvecs++ is just plain
wrong. It breaks log recovery completely, and it would seem the only
reason this hasn't been since then is that we don't log large
contigous regions of multi-page unmapped buffers very often. Never
would be a closer estimate, at least until the CRC code came along....
So, lets fix that by restoring the nvecs accounting for the extra
region when we hit this case.....
.... and there's the problemin log recovery it is apparently working
around:
XFS: Assertion failed: i == item->ri_total, file: fs/xfs/xfs_log_recover.c, line: 2135
Yup, xlog_recover_do_reg_buffer() doesn't handle contigous dirty
regions being broken up into multiple regions by the log formatting
code. That's an easy fix, though - if the number of contiguous dirty
bits exceeds the length of the region being copied out of the log,
only account for the number of dirty bits that region covers, and
then loop again and copy more from the next region. It's a 2 line
fix.
Now xfstests xfs/085 passes, we have one less piece of mystery
code, and one more important piece of knowledge about how to
structure new log format items..

x86-64, init: Fix a possible wraparound bug in switchover in head_64.S
In head_64.S, a switchover has been used to handle kernel crossing
1G, 512G boundaries.
And commit 8170e6bed465b4b0c7687f93e9948aca4358a33b
x86, 64bit: Use a #PF handler to materialize early mappings on demand
said:
During the switchover in head_64.S, before #PF handler is available,
we use three pages to handle kernel crossing 1G, 512G boundaries with
sharing page by playing games with page aliasing: the same page is
mapped twice in the higher-level tables with appropriate wraparound.
But from the switchover code, when we set up the PUD table:
114 addq $4096, %rdx
115 movq %rdi, %rax
116 shrq $PUD_SHIFT, %rax
117 andl $(PTRS_PER_PUD-1), %eax
118 movq %rdx, (4096+0)(%rbx,%rax,8)
119 movq %rdx, (4096+8)(%rbx,%rax,8)
It seems line 119 has a potential bug there. For example,
if the kernel is loaded at physical address 511G+1008M, that is 000000000111111111111111000000000000000000000000
and the kernel _end is 512G+2M, that is 000000001000000000000000001000000000000000000000
So in this example, when using the 2nd page to setup PUD (line 114~119),
rax is 511.
In line 118, we put rdx which is the address of the PMD page (the 3rd page)
into entry 511 of the PUD table. But in line 119, the entry we calculate from
(4096+8)(%rbx,%rax,8) has exceeded the PUD page. IMO, the entry in line
119 should be wraparound into entry 0 of the PUD table.
The patch fixes the bug.

"Two more fixes:
The first one was reported by Mauro Carvalho Chehab, where if a poll()

it will crash the kernel, as buffers are only created when a CPU comes
on line, but the trace files are for all possible CPUs.
This fix is to check if the buffer was allocated and if not return
-EINVAL.
That was the simple fix, the real fix is a bit more complex and not
for a -rc release. We could have the files created when the CPUs come
online. That would require some design changes.
The second one was reported by Peter Zijlstra. If the kernel command
line has ftrace=nop, it will lock up the system on boot up. This is
because the new design for 3.10 has the nop tracer bootstrap the
tracing subsystem. When ftrace=<trace> is defined, when a that tracer
is registered, it starts the tracing, but uses the nop tracer to clear
things out. What happened here was that ftrace=nop caused the
registering of nop to start it and use nop before it was initialized.
The only thing nop needs to have done to initialize it is to have the
tracer point its current_tracer structure member to the nop tracer.
Doing that before registering the nop tracer makes everything work."

ARC: lazy dcache flush broke gdb in non-aliasing configs
gdbserver inserting a breakpoint ends up calling copy_user_page() for a
code page. The generic version of which (non-aliasing config) didn't set
the PG_arch_1 bit hence update_mmu_cache() didn't sync dcache/icache for
corresponding dynamic loader code page - causing garbade to be executed.
So now aliasing versions of copy_user_highpage()/clear_page() are made
default. There is no significant overhead since all of special alias
handling code is compiled out for non-aliasing build

aio: fix kioctx not being freed after cancellation at exit time
The recent changes overhauling fs/aio.c introduced a bug that results in
the kioctx not being freed when outstanding kiocbs are cancelled at
exit_aio() time. Specifically, a kiocb that is cancelled has its
completion events discarded by batch_complete_aio(), which then fails to
wake up the process stuck in free_ioctx(). Fix this by modifying the
wait_event() condition in free_ioctx() appropriately.
This patch was tested with the cancel operation in the thread based code
posted yesterday.
