in some LSI SCSI devices not being discovered.  This adds a quirk to
ignore _SEG on this machine and default to zero.

The xw9300 has three host bridges:

    ACPI: PCI Root Bridge [PCI0] (domain 0000 [bus 00-3f])
    ACPI: PCI Root Bridge [PCI1] (domain 0001 [bus 40-7f])

default), the _SEG methods of the PCI1 and PCI2 bridges return 1 and 2,
respectively.  However, the BIOS implementation appears to be incomplete,
and we can't enumerate devices in those domains.

But if we assume PCI1 and PCI2 really lead to buses in domain 0,
everything works fine.  Windows XP and Vista also seem to ignore
these _SEG methods.

xfs: fix reading of wrapped log data

Commit 4439647 ("xfs: reset buffer pointers before freeing them") in
3.0-rc1 introduced a regression when recovering log buffers that
wrapped around the end of log. The second part of the log buffer at
the start of the physical log was being read into the header buffer
rather than the data buffer, and hence recovery was seeing garbage
in the data buffer when it got to the region of the log buffer that
was incorrectly read.

11 years agoxfs: fix buffer shudown reference count mismatch
Dave Chinner [Fri, 2 Nov 2012 03:23:12 +0000 (14:23 +1100)]
xfs: fix buffer shudown reference count mismatch

When we shut down the filesystem, we have to unpin and free all the
buffers currently active in the CIL. To do this we unpin and remove
them in one operation as a result of a failed iclogbuf write. For
buffers, we do this removal via a simultated IO completion of after
marking the buffer stale.

At the time we do this, we have two references to the buffer - the
active LRU reference and the buf log item.  The LRU reference is
removed by marking the buffer stale, and the active CIL reference is
by the xfs_buf_iodone() callback that is run by
xfs_buf_do_callbacks() during ioend processing (via the bp->b_iodone
callback).

However, ioend processing requires one more reference - that of the
IO that it is completing. We don't have this reference, so we free
the buffer prematurely and use it after it is freed. For buffers
marked with XBF_ASYNC, this leads to assert failures in
xfs_buf_rele() on debug kernels because the b_hold count is zero.

Fix this by making sure we take the necessary IO reference before
starting IO completion processing on the stale buffer, and set the
XBF_ASYNC flag to ensure that IO completion processing removes all
the active references from the buffer to ensure it is fully torn
down.

11 years agopkt_sched: enable QFQ to support TSO/GSO
Paolo Valente [Mon, 5 Nov 2012 20:29:24 +0000 (20:29 +0000)]
pkt_sched: enable QFQ to support TSO/GSO

If the max packet size for some class (configured through tc) is
violated by the actual size of the packets of that class, then QFQ
would not schedule classes correctly, and the data structures
implementing the bucket lists may get corrupted. This problem occurs
with TSO/GSO even if the max packet size is set to the MTU, and is,
e.g., the cause of the failure reported in [1]. Two patches have been
proposed to solve this problem in [2], one of them is a preliminary
version of this patch.

This patch addresses the above issues by: 1) setting QFQ parameters to
proper values for supporting TSO/GSO (in particular, setting the
maximum possible packet size to 64KB), 2) automatically increasing the
max packet size for a class, lmax, when a packet with a larger size
than the current value of lmax arrives.

The drawback of the first point is that the maximum weight for a class
is now limited to 4096, which is equal to 1/16 of the maximum weight
sum.

Finally, this patch also forcibly caps the timestamps of a class if
they are too high to be stored in the bucket list. This capping, taken
from QFQ+ [3], handles the unfrequent case described in the comment to
the function slot_insert.
