check_unreachable_inodes does work in online mode, with the one caveat
that it assumes check_dirents has also run - and check_dirents is not
PASS_ONLINE yet.

Ensure that snapshot_tree.master_subvol is cleared when we delete the
master subvolume in a tree of snapshots, and allow for snapshot trees
that don't have a master subvolume in fsck.
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
|
|
Previously, fsck used the snapshot tree's master subvol for finding the
root inode number - but the master subvol might have been deleting, and
setting a new one should be a user operation; meaning we can't rely on
it existing.
Fortunately, for finding the root inode number in a tree of snapshots,
finding any associated subvolume works.

Locking considerations (possibly no longer relevant?) mean that when an
accounting update needs a new superblock replicas entry to be created,
it's deferred to the transaction commit error path.
But accounting updates for gc/fcsk aren't done from the transaction
commit path - so we need to handle
-BCH_ERR_btree_insert_need_mark_replicas locally.

In bcachefs, io_read and io_write counter record the amount
of data which has been read and written. They increase in
unit of sector, so to display correctly, they need to be
shifted to the left by the size of a sector. Other counters
like io_move, move_extent_{read, write, finish} also have
this problem.
In order to support different unit, we add extra column to
mark the counter type by using TYPE_COUNTER and TYPE_SECTORS
in BCH_PERSISTENT_COUNTERS().

Persistent cursors for inode allocation.
A free inodes btree would add substantial overhead to inode allocation
and freeing - a "next num to allocate" cursor is always going to be
faster.
We just need it to be persistent, to avoid scanning the inodes btree

When jumping to 'martian_destination' a drop reason is always set but
that label falls-through the 'e_nobufs' one, overriding the value.
The behavior was introduced by the mentioned commit. The logic went
from,
goto martian_destination;
...
martian_destination:
...
e_inval:
err = -EINVAL;
goto out;
e_nobufs:
err = -ENOBUFS;
goto out;
to,
reason = ...;
goto martian_destination;
...
martian_destination:
...
e_nobufs:
reason = SKB_DROP_REASON_NOMEM;
goto out;
A 'goto out' is clearly missing now after 'martian_destination' to avoid
overriding the drop reason.

CPSW ALE has 75-bit ALE entries stored across three 32-bit words.
The cpsw_ale_get_field() and cpsw_ale_set_field() functions support
ALE field entries spanning up to two words at the most.
The cpsw_ale_get_field() and cpsw_ale_set_field() functions work as
expected when ALE field spanned across word1 and word2, but fails when
ALE field spanned across word2 and word3.
For example, while reading the ALE field spanned across word2 and word3
(i.e. bits 62 to 64), the word3 data shifted to an incorrect position
due to the index becoming zero while flipping.
The same issue occurred when setting an ALE entry.
This issue has not been seen in practice but will be an issue in the future
if the driver supports accessing ALE fields spanning word2 and word3
Fix the methods to handle getting/setting fields spanning up to two words.

scsi_check_passthrough() is always called, but it doesn't check for if a
command completed successfully. As a result, if a command was successful and
the caller used SCMD_FAILURE_RESULT_ANY to indicate what failures it wanted
to retry, we will end up retrying the command. This will cause delays during
device discovery because of the command being sent multiple times. For some
USB devices it can also cause the wrong device size to be used.
This patch adds a check for if the command was successful. If it is we
return immediately instead of trying to match a failure.

Here are two minor improvement/fixes in the PMU event path. The first patch
was part of the series[1]. The 2nd patch was suggested during the series
review.
While the series can only be merged once SBI v3.0 is frozen, these two

The SBI specification allows only lower 48bits of hpmeventX to be
configured via SBI PMU. Currently, the driver masks of the higher
bits but doesn't return an error. This will lead to an additional
SBI call for config matching which should return for an invalid
event error in most of the cases.
However, if a platform(i.e Rocket and sifive cores) implements a
bitmap of all bits in the event encoding this will lead to an
incorrect event being programmed leading to user confusion.
Report the error to the user if higher bits are set during the
event mapping itself to avoid the confusion and save an additional
SBI call.
