sata_mv:  Fix broken Marvell 7042 support.

The Marvell 7042 chip is more or less the same as the 6042 internally,
but sports a PCIe bus.  Despite having identical SATA cores, the 7042
does differ from its PCI bus counterparts in placment and layout of
certain bus related registers.

This patch fixes sata_mv to distinguish between the PCI bus registers
of earlier chips, and the PCIe bus registers of the 7042.

Specifically, move the offsets and bit patterns for the
PCI/PCIe interrupt cause/mask registers into the struct mv_host_priv,
as these values differ between the 6xxx and 7xxx series chips.

This fixes the driver to not access reserved PCI addresses,
and prevents the lockups reported in linux-2.6.24 with 7042 boards.

Also add a new PCI ID for the Highpoint 2300 7042-based board
that I'm using for testing this stuff here.

Tested with Marvell 6081 + 7042 chips, on x86 & x86_64.

Eric W. Biederman [Sat, 1 Dec 2007 13:33:17 +0000 (00:33 +1100)]
[NETNS]: Fix /proc/net breakage

Well I clearly goofed when I added the initial network namespace support
for /proc/net.  Currently things work but there are odd details visible to
user space, even when we have a single network namespace.

Since we do not cache proc_dir_entry dentries at the moment we can just
modify ->lookup to return a different directory inode depending on the
network namespace of the process looking at /proc/net, replacing the
current technique of using a magic and fragile follow_link method.

To accomplish that this patch:
- introduces a shadow_proc method to allow different dentries to
  be returned from proc_lookup.
- Removes the old /proc/net follow_link magic
- Fixes a weakness in our not caching of proc generic dentries.

As shadow_proc uses a task struct to decided which dentry to return we can
go back later and fix the proc generic caching without modifying any code
that uses the shadow_proc method.

solutions. But this patch fixed the connection problem when switching
from a WPA enabled AP (using wpa_supplicant) to an open AP (using
iwconfig). The root cause is when we connect to a WPA enabled AP,
wpa_supplicant sets the ifsta->extra_ie thru SIOCSIWGENIE. But if we
stop wpa_supplicant and connect to an open AP with iwconfig, there is
no way to clear the extra_ie so that mac80211 keeps connecting with that.

Someone could argue wpa_supplicant should clear the extra_ie during
its shutdown. But mac80211 should also handle the unexpected shutdown
case (ie. killall -9 wpa_supplicant).

x86/paravirt: revert exports to restore old behaviour

Subdividing the paravirt_ops structure caused a regression in certain
non-GPL modules which try to use mmu_ops and cpu_ops.  This restores the
old behaviour, and makes it consistent with the non-CONFIG_PARAVIRT case.

Takashi Iwai <tiwai@suse.de> adds:
> I took at this problem (as I have an nvidia card on one of my

Christoph Hellwig objects to this patch on the grounds that modules
shouldn't be using these operations anyway.  I don't think this is a
particularly good reason to reject the patch, for several reasons:

1. These operations are still available to modules when not using
   CONFIG_PARAVIRT, since they are implicitly exported as inline
   functions via the kernel headers.  Exporting the same functionality as
   GPL-only symbols just adds a gratuitious difference between
   CONFIG_PARAVIRT and non-CONFIG_PARAVIRT configurations.  If we really
   think these operations are not for module use (or non-GPL module use),
   then we should solve the problem in a general way.

2. It's a regression from previous kernels, which would work these
   modules even with CONFIG_PARAVIRT enabled.

3. The operations in question seem pretty reasonable for modules to
   use.  The control registers/MSRs can be accessed directly anyway, so there's
   no benefit in preventing modules from using standard interfaces.  And it seems
   reasonable to allow a graphics driver to create its own mappings if it wants.

Therefore, I think this patch should go in for 2.6.24.  If people
really think that these operations should not be available to modules,
then we can address that separately.

14 years agofuse: fix uninitialized field in fuse_inode

fuse: fix uninitialized field in fuse_inode

I found problems accessing (executing) previously existing files, until
I did chmod on them (or setattr).

If the fi->attr_version is not initialized, then it could be
larger than fc->attr_version until a setattr is executed, and as a
result the inode attributes would never be set.

fuse: fix FUSE_FILE_OPS sending

FUSE_FILE_OPS is meant to signal that the kernel will send the open file to to
the userspace filesystem for operations on open files, so that sillyrenaming
unlinked files becomes unnecessary.

However this needs VFS changes, which won't make it into 2.6.24.

14 years agofuse: pass open flags to read and write
Miklos Szeredi [Thu, 29 Nov 2007 00:22:00 +0000 (16:22 -0800)]
fuse: pass open flags to read and write

Some open flags (O_APPEND, O_DIRECT) can be changed with fcntl(F_SETFL, ...)
after open, but fuse currently only sends the flags to userspace in open.

To make it possible to correcly handle changing flags, send the
current value to userspace in each read and write.

14 years agofuse: fix reading past EOF

fuse: fix reading past EOF

Currently reading a fuse file will stop at cached i_size and return
EOF, even though the file might have grown since the attributes were
last updated.

So detect if trying to read past EOF, and refresh the attributes
before continuing with the read.

Thanks to mpb for the report.
