5 weeks agoe2fsck: track errors/badness found for each inode
Andreas Dilger [Fri, 13 Apr 2012 07:13:58 +0000 (01:13 -0600)]
e2fsck: track errors/badness found for each inode

The present e2fsck code checks the inode, per field basis.  It
doesn't take into consideration to total sanity of the inode.
This may cause e2fsck turning a garbage inode into an apparently
sane inode ("It is a vessel of fertilizer, and none may abide
its strength").

Add heuristics into fix_problem() so that e2fsck tracks the degree
of badness of an inode, without needing to be added in many places
in code and explicitly set. An icount is used to keep track the
badness of every inode.  Take advantage of pctx->ino almost always
pointing at the bad inode and increment badness when fix_problem()
is called on an inode.  This also handles future problem addition.

That leaves only a handful of places in the code that need special
handling to either set a higher badness (e.g. inode blocks that are
directly referencing filesystem metadata or have wildly incorrect
timestamps), or should not contribute to inode badness at all.

Badness above a certain threshold value results in clearing the
inode.  The default badness threshold value is 12, it can be tuned
for e2fsck using "-E inode_badness_threshold=<value>" if needed.

When multiply-claimed blocks are found, this is often caused by a
corrupted inode or indirect block that causes a bad inode to overlap
with many good inodes.  This problem is made worse when running
on a large filesystem (16TB or more) because random 32-bit numbers
in the inode->i_blocks[] array are always "valid" block numbers
(with smaller filesystems the random block numbers would be detected
as an error).  Garbage triple/double/indirect blocks will also point
to random "valid" blocks that will themselves contain random 32-bit
block numbers and multiply duplicate blocks count exponentially.

Rather than clone all of those blocks, or possibly deleting/zeroing
all such inodes (as done with "-E shared=delete") it would be better
to find the "bad" inode(s) causing the most problems, and clear only
those inodes, rather than clearing all of inodes with shared blocks.
However, care should be taken to avoid spuriously clearing inodes
that only share blocks with a small number of peers, as it is
difficult to know for sure in this case which inode is the bad one.

An added difficulty in implementing this is that the full list of
inodes sharing a given block is only available in pass1d, at which
point it is already starting to clone the shared blocks.  Some checks
could be done in pass1b, by penalizing inodes wiht the most shared
*blocks*, but it is better to count the shared *inodes*.

If a bad inode is found in pass1b it can be cleared before adding it
to the shared cluster/inode dictionaries.  Otherwise, if found in
pass1d the code to remove inodes/cluster dict_delete_free() code is
non-functional.  For now, restart e2fsck pass1 if very bad inodes
are found.  This will not affect already-processed inodes, and should
reduce the number of duplicate blocks significantly.

Add a new f_ibadness_dup test case for a many-conflicting inode.
Update f_ind_inode_collision, which is a many-blocks conflicting
case that is much better handled by this new mechanism.

6 weeks agoe2fsck: allow deleting or zeroing shared blocks
Andreas Dilger [Thu, 12 Apr 2012 23:32:53 +0000 (17:32 -0600)]
e2fsck: allow deleting or zeroing shared blocks

E2fsck fixes files that are found to be sharing blocks by cloning
the shared blocks and giving each file a private copy in pass 1D.

Allowing all files claiming the shared blocks to have copies can
inadvertantly bypass access restrictions.  Deleting all the files,
zeroing the cloned blocks, or placing the files in the /lost+found
directory after cloning may be preferable in some secure environments.

The following patches implement config file and command line options
in e2fsck that allow pass 1D behavior to be tuned according to site
policy.  It adds two extended options and config file counterparts.
On the command line:

 -E clone=dup|zero

    Select the block cloning method.  "dup" is old behavior,
    and is the default.  "zero" is a new method that substitutes
    zero-filled blocks for the shared blocks in all the files
    that claim them.

 -E shared=preserve|lost+found|delete

    Select the disposition of files containing shared blocks.
    "preserve" is the old behavior which remains the default.
    "lost+found" causes files to be unlinked after cloning so
    they will be reconnected to /lost+found in pass 3.
    "delete" skips cloning entirely and simply deletes the files.

In the config file:
  [options]
      clone=dup|zero
      shared=preserve|lost+found|delete

filefrag: Lustre changes to filefrag FIEMAP handling

Add support for multiple-device filesystems by defining a new
fe_device field in the fiemap_extent structure.  This allows
printing the filesystem-relative or linux block device number
associated with each extent of a file.  If a single filesystem
extent is mirrored to multiple block devices, the fe_device
field can be used to disambiguate the multiple copies.

If the "-l" (device-logical) option is given to filefrag, then
all extents for a particular device of a file are returned
before returning extents for the next device.  This makes it
easier to see if extent allocation within a single device is
contiguous, instead of returning all of the blocks of a file
interleaved in file-logical-offset order.

Lustre uses the high 16bits of fiemap_extent:fe_device to record
the absolute stripe number being processed, so that next fiemap
call continues from that stripe, which allows files that have
multiple objects on the same device to work properly (FLR, PFL).
Older filefrag will print the stripe number with the OST index.

Andreas Dilger [Sat, 8 Oct 2022 06:02:49 +0000 (00:02 -0600)]
LU-16169 e2fsck: improve parallel thread balance

Improve the balance of work allocated to each thread by distributing
a more equal number of inodes to each thread, rather than an equal
number of groups.

In some cases in real usage, the number of inodes allocated to
threads with equal numbers of groups can vary by 10x or more, which
leads to pass1 threads having a runtime time roughly propritional
to the number of inodes allocated to them.

Calculate the average number of *used* inodes for each thread to
process instead of the overall average number of inodes in the
filesystem per thread.  Otherwise, if the filesystem is not very
full it will allocate too many groups to the first threads and
none to the last threads.

For example, a filesystem with a total of 5242880 inodes, with
3789293 used inodes should process on average 473661 used inodes
per thread with 8 threads, but this wasn't the case:

    # e2fsck -fn -m8 /dev/vgmyth/lvmythmdt0.ssd
    Pass 1: Checking inodes, blocks, and sizes
    [Thread 0] Scan group range [0, 20), inode_count = 655358/655360
    [Thread 1] Scan group range [20, 40), inode_count = 655360/655360
    [Thread 2] Scan group range [40, 66), inode_count = 647340/655360
    [Thread 3] Scan group range [66, 92), inode_count = 651555/655360
    [Thread 4] Scan group range [92, 112), inode_count = 655360/655360
    [Thread 5] Scan group range [112, 160), inode_count = 524320/655360
    [Thread 6] Scan group range [159, 160), inode_count = 0/655360
    [Thread 7] Scan group range [159, 160), inode_count = 0/655360

With the fix the thread balance is much better, with each thread
processing approximately the same number of used inodes, even the
last thread which has more groups but with fewer used inodes:

    Pass 1: Checking inodes, blocks, and sizes
    [Thread 0] Scan group range [0, 13], used inodes 458750/458752
    [Thread 1] Scan group range [14, 28], used inodes 491520/491520
    [Thread 2] Scan group range [29, 42], used inodes 458752/458752
    [Thread 3] Scan group range [43, 63], used inodes 486191/688128
    [Thread 4] Scan group range [64, 84], used inodes 485024/688128
    [Thread 5] Scan group range [85, 98], used inodes 458752/458752
    [Thread 6] Scan group range [99, 113], used inodes 491520/491520
    [Thread 7] Scan group range [114, 159], used inodes 458784/1507328

Also print the group ranges as closed sets so the brackets align.

ext2fs.h header, since it is currently only used in that one
function.  It is too large to be a static inline function, and
it is currently causing many compile warnings because it is
not marked with "_INLINE_".

a small fraction (1/15th) of the number of blocks zeroed when
"-E assume_storage_prezeroed" is not given, which makes it more
robust when running in different environments.  This varies from
1/16 in the original test to 1/91 in my local test environment.

Avoid "losetup --sector-size 4096", use "mke2fs -b 4096" instead.
Clean up the loop device before checking "stat" so that all

AOSP: Use no_full_install: true instead of installable: false

So far, we have used `instalable: false` to avoid collision with the
other modules that are installed to the same path. A typical example was
<foo> and <foo>.microdroid. The latter is a modified version of the
former for the inclusion of the microdroid image. They however both have
the same instalation path (ex: system/bin) and stem (ex: foo) so that we
can reference them using the same path regardless of whether we are in
Android or microdroid.

However, the use of `installable: false` for the purpose is actually
incorrect, because `installable: false` also means, obviously, "this
module shouldn't be installed". The only reason this incorrect way has
worked is simply because packaging modules (ex: android_filesystem)
didn't respect the property when gathering the modules.

As packaging modules are now fixed to respect `installable: false`, we
need a correct way of avoiding the collision. `no_full_install: true` is
it.

If a module has this property set to true, it is never installed to the
full instal path like out/target/product/<partition>/... It can be
installed only via packaging modules.

AOSP: ext2simg: fix off-by-one errors causing corruption

The chunk_end parameter to add_chunk() is exclusive, but two callers
incorrectly treat it as inclusive: when the maximum chunk length of
'INT32_MAX - 12' bytes is reached, and when a chunk extends to the very
end of the filesystem.  The result is that the output simg file contains
zeroes for the last block of these chunks instead of the correct data.

A related bug is that the expanded size of the simg file is set to the
filesystem size (in blocks) minus s_first_data_block.  On filesystems
where s_first_data_block != 0, i.e. 1K blocksize filesystems without
bigalloc enabled, this truncates the last block of the filesystem.

Fix these bugs by (a) making add_chunk() take the chunk length and
passing the correct values, and (b) using the filesystem size properly.

Here is a reproducer that shows the last block of the filesystem being
truncated (bsize=1024) and being corrupted with zeroes (bsize=4096):

    for bsize in 1024 4096; do
        rm -f ext4.img
        mkfs.ext4 -b $bsize ext4.img 10000
        mkdir -p mnt
        sudo mount -t ext4 -o loop ext4.img mnt
        sudo cp /dev/urandom mnt/fill
        sudo umount mnt
        ext2simg ext4.img ext4.simg
        simg2img ext4.simg ext4.img.restored
        cmp ext4.img ext4.img.restored
    done

AOSP: Mostly restore -Werror for macOS build

It turns out the "Can't use getmntent or getmntinfo" warning was the
only warning remaining in the macOS build via the Android build system.
So now that it's fixed, -Wno-error can be removed.

That being said, the upstream CI (GitHub Actions) currently uses
-Wno-error=deprecated-declarations for the macOS build, since it's still
needed for some files (which aren't built by the Android build system).

For now, let's just replace -Wno-error with
-Wno-error=deprecated-declarations to match what the upstream CI uses.

AOSP: Android: define HAVE_GETMNTINFO on macOS

macOS supports getmntinfo(), but not getmntent().  To match what the
'configure' script detects, define HAVE_GETMNTINFO to 1.

This prevents the following warning:

    #warning "Can't use getmntent or getmntinfo to check for mounted filesystems!"

AOSP: Revert "Android: stop suppressing warnings from macOS build"

Unfortunately, the macOS build is not tested either by presubmit or by
local builds.  A macOS build *is* being tested in the upstream GitHub
Actions workflow now; however, that uses the autotools-based build
system, and there can be issues specific to the Android build system.

As a result, removing -Wno-error was not safe yet, and the macOS build
is currently broken in postsubmit.  As there could be multiple issues,
let's restore -Wno-error until I've had a chance to fix the warnings.
