[PATCH] NFS: Fix races in nfs_revalidate_mapping()

2007-01-24T20:31:06+00:00

Prevent the call to invalidate_inode_pages2() from racing with file writes
by taking the inode->i_mutex across the page cache flush and invalidate.

libata: Initialize qc->pad_len

2007-01-24T07:04:34+00:00

Initialize qc->pad_len for each new command. This ensures
that pad_len is not set to a stale value for zero data
length commands.

libata: Fixup n_elem initialization

2007-01-24T07:04:34+00:00

Fixup the inialization of qc->n_elem. It currently gets
initialized to 1 for commands that do not transfer any data.
Fix this by initializing n_elem to 0 and only setting to 1
in ata_scsi_qc_new when there is data to transfer. This fixes
some problems seen with SATA devices attached to ipr adapters.

[IP] TUNNEL: Fix to be built with user application.

2007-01-24T06:17:23+00:00

include/linux/if_tunnel.h is broken for user application
because it was changed to use __be32 which is required
to include linux/types.h in advance but didn't.

(This issue is found when building MIPL2 daemon. We are not sure this
is the last header to be fixed about __be32.)

[NETFILTER]: Fix iptables ABI breakage on (at least) CRIS

2007-01-24T06:00:13+00:00

With the introduction of x_tables we accidentally broke compatibility
by defining IPT_TABLE_MAXNAMELEN to XT_FUNCTION_MAXNAMELEN instead of
XT_TABLE_MAXNAMELEN, which is two bytes larger.

On most architectures it doesn't really matter since we don't have
any tables with names that long in the kernel and the structure
layout didn't change because of alignment requirements of following
members. On CRIS however (and other architectures that don't align
data) this changed the structure layout and thus broke compatibility
with old iptables binaries.

Changing it back will break compatibility with binaries compiled
against recent kernels again, but since the breakage has only been
there for three releases this seems like the better choice.

[PATCH] resierfs: avoid tail packing if an inode was ever mmapped

2007-01-23T15:52:06+00:00

This patch fixes a confusion reiserfs has for a long time.

On release file operation reiserfs used to try to pack file data stored in
last incomplete page of some files into metadata blocks.  After packing the
page got cleared with clear_page_dirty.  It did not take into account that
the page may be mmaped into other process's address space.  Recent
replacement for clear_page_dirty cancel_dirty_page found the confusion with
sanity check that page has to be not mapped.

The patch fixes the confusion by making reiserfs avoid tail packing if an
inode was ever mmapped.  reiserfs_mmap and reiserfs_file_release are
serialized with mutex in reiserfs specific inode.  reiserfs_mmap locks the
mutex and sets a bit in reiserfs specific inode flags.
reiserfs_file_release checks the bit having the mutex locked.  If bit is
set - tail packing is avoided.  This eliminates a possibility that mmapped
page gets cancel_page_dirty-ed.
