11 years agoipv6: skb_dst() can be NULL in ipv6_hop_jumbo().
David S. Miller [Thu, 14 Jan 2010 01:27:37 +0000]
ipv6: skb_dst() can be NULL in ipv6_hop_jumbo().

This fixes CERT-FI FICORA #341748

Discovered by Olli Jarva and Tuomo Untinen from the CROSS
project at Codenomicon Ltd.

Just like in CVE-2007-4567, we can't rely upon skb_dst() being
non-NULL at this point.  We fixed that in commit
e76b2b2567b83448c2ee85a896433b96150c92e6 ("[IPV6]: Do no rely on
skb->dst before it is assigned.")

However commit 483a47d2fe794328d29950fe00ce26dd405d9437 ("ipv6: added
net argument to IP6_INC_STATS_BH") put a new version of the same bug
into this function.

Complicating analysis further, this bug can only trigger when network
namespaces are enabled in the build.  When namespaces are turned off,
the dev_net() does not evaluate it's argument, so the dereference
would not occur.

So, for a long time, namespaces couldn't be turned on unless SYSFS was
disabled.  Therefore, this code has largely been disabled except by
people turning it on explicitly for namespace development.

tg3: Fix std rx prod ring handling

There are some tg3 devices that require the driver to post new rx
buffers in smaller increments.  Commit
4361935afe3abc3e5a93006b99197fac1fabbd50, "tg3: Consider
rx_std_prod_idx a hw mailbox" changed how the driver tracks the rx
producer ring updates, but it does not make any special considerations
for the above-mentioned devices.  For those devices, it is possible for
the driver to hit the special case path, which updates the hardware
mailbox register but skips updating the shadow software mailbox member.
If the special case path represents the final mailbox update for this
ISR iteration, the hardware and software mailbox values will be out of
sync.  Ultimately, this will cause the driver to use a stale mailbox
value on the next iteration, which will appear to the hardware as a
large rx buffer update.  Bad things ensue.

The fix is to update the software shadow mailbox member when the special
case path is taken.

11 years agozlib: Fix build of powerpc boot wrapper
Benjamin Herrenschmidt [Wed, 13 Jan 2010 05:19:34 +0000]
zlib: Fix build of powerpc boot wrapper

Commit ac4c2a3bbe5db5fc570b1d0ee1e474db7cb22585 broke the build
of all powerpc boot wrappers.

It attempts to add an include of autoconf.h but used the wrong
path for it. It also adds -D__KERNEL__ to our boot wrapper, both
things that we pretty much didn't do on purpose so far.

We want our boot wrapper to remain independent enough of the kernel
for various reasons, one of them being that you can "wrap" an existing
kernel at distro install time which allows to ship one kernel image
and a set of boot wrappers for different platforms, the wrappers
don't have to be built out of the same kernel build tree.

It's also incorrect to do what the patch does in our boot environment
since we may not have a proper alignment exception handler which means
we may not be able to fixup the few cases where an unaligned access will
need SW emulation (depends on the core variant, could be when crossing
page or segment boundaries for example).

This patch fixes it by putting the old code back in and using the
new "fancy" variant only when CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS
is set, which happens not to be set on powerpc since we don't include
autoconf.h. It also reverts the changes to our boot wrapper Makefile.

This means that x86 should, afaik, keep the optimisations since its
boot wrapper does include autoconf.h and define __KERNEL__ (though I
doubt they make that much different outside of slow embedded processors).

But new truncate_pagecache() in vmtuncate() does nothing if new < old.

So, this patch fixes it by removing "new < old" check. It would need

Makefile: do not override LC_CTYPE

Setting LC_CTYPE=C breaks localized messages in some setups. With only
LC_COLLATE=C and LC_NUMERIC=C, we get almost all we need, except for not
so defined character classes and tolower()/toupper(). The former is not
a big issue, because we can assume that e.g. [:alpha:] will always
include a-zA-Z and we only ever process ASCII input. The latter seems
only affect arch/sh/tools/gen-mach-types, which we can handle separately.

So after this patch the meaning of ranges like [a-z], the behavior of
sort and join, etc. should be the same everywhere and at the same time
gcc should be able to print localized waring and error messages.
LC_NUMERIC=C might not be necessary, but setting it doesn't hurt.

kbuild: really fix bzImage build with non-bash sh

In an x86 build with CONFIG_KERNEL_LZMA enabled and dash as sh,
arch/x86/boot/compressed/vmlinux.bin.lzma ends with
'\xf0\x7d\x39\x00' (16 bytes) instead of the 4 bytes intended and
the resulting vmlinuz fails to boot.  This improves on the
previous behavior, in which the file contained the characters
'-ne ' as well, but not by much.

Previous commits replaced "echo -ne" first with "/bin/echo -ne",
then "printf" in the hope of improving portability, but none of
these commands is guaranteed to support hexadecimal escapes on
POSIX systems.  So use the shell to convert from hexadecimal to
octal.

With this change, an LZMA-compressed kernel built with dash as sh
boots correctly again.

xen: fix hang on suspend.

In 65f63384 "xen: improve error handling in do_suspend" I said:
    - xs_suspend()/xs_resume() and dpm_suspend_noirq()/dpm_resume_noirq() were not
      nested in the obvious way.
and changed the ordering of the calls as so:
    BEFORE AFTER
    xs_suspend dpm_suspend_noirq
    dpm_suspend_noirq xs_suspend
    *SUSPEND* *SUSPEND*
    dpm_resume_noirq dpm_resume_noirq
    xs_resume xs_resume
Clearly this is not an improvement and I was talking rubbish.

In particular the new ordering is susceptible to a hang if a xenstore write is
in progress at the point at which the suspend kicks in. When the suspend
process calls xs_suspend it tries to take the request_mutex but if a write is
in progress it could be looping in xenbus_xs.c:read_reply() waiting for
something to arrive on &xs_state.reply_list while holding the request_mutex
(taken in the caller of read_reply).

However if we have done dpm_suspend_noirq before xs_suspend then we won't get
any more xenstore interrupts and process_msg() will never be woken up to add
anything to the reply_list.

Fix this by calling xs_suspend before dpm_suspend_noirq. If dpm_suspend_noirq
fails then make sure we go through the xs_suspend_cancel() code path.

11 years agosata_promise: don't classify overruns as HSM errors
Mikael Pettersson [Sat, 9 Jan 2010 22:32:06 +0000]
sata_promise: don't classify overruns as HSM errors

When sata_promise encounters an overrun or underrun error it
translates that to a libata AC_ERR_HSM, causing a hard reset.
Since over/under-runs were thought to be rare and transient,
this action seemed reasonable.

Unfortunately it turns out that the controller throws overrun
errors when e.g. hal polls a CD or DVD writer containing blank
media, causing long sequences of hard resets and retries before
EH finally gives up.

This patch updates sata_promise to classify over/under-runs as
AC_ERR_OTHER instead. This allows libata EH and upper layers to
retry or fail the operation as they see fit without the disruption
caused by repeated hard resets.

This fixes a problem using a DVD-RAM drive with sata_promise,
reported by Thomas Schorpp. I also tested it on a DVD-RW drive.

pcibus_to_node can return -1 if we cannot determine which node a pci bus

Change cpumask_of_node to check for -1 and return cpu_all_mask in this

mac80211: fix queue selection for data frames on monitor interfaces

When ieee80211_monitor_select_queue encounters data frames, it selects
the WMM AC based on skb->priority and assumes that skb->priority
contains a valid 802.1d tag. However this assumption is incorrect, since
ieee80211_select_queue has not been called at this point.
If skb->priority > 7, an array overrun occurs, which could lead to
invalid values, resulting in crashes in the tx path.
Fix this by setting skb->priority based on the 802.11 header for QoS
frames and using the default AC for all non-QoS frames.

11 years agocore, x86: make LIST_POISON less deadly
Avi Kivity [Sun, 10 Jan 2010 14:28:09 +0000]
core, x86: make LIST_POISON less deadly

The list macros use LIST_POISON1 and LIST_POISON2 as undereferencable
pointers in order to trap erronous use of freed list_heads.  Unfortunately
userspace can arrange for those pointers to actually be dereferencable,
potentially turning an oops to an expolit.

To avoid this allow architectures (currently x86_64 only) to override
the default values for these pointers with truly-undereferencable values.
This is easy on x86_64 as the virtual address space is large and contains
areas that cannot be mapped.

Other 64-bit architectures will likely find similar unmapped ranges.

[ingo: switch to 0xdead000000000000 as the unmapped area]
[ingo: add comments, cleanup]
[jaswinder: eliminate sparse warnings]

11 years agomn10300: make the ASB2305's PCnet32 NIC work by using the PCI bridge's SRAM

mn10300: make the ASB2305's PCnet32 NIC work by using the PCI bridge's SRAM

Access to the ASB2305's PCnet32 NIC doesn't work correctly because when
the NIC attempts to update the ring buffer flags by DMA, the change to RAM
crops up about 17uS after the interrupt line is asserted.  This is almost
certainly due to a bug in the PCI bridge FPGA on that board.

We can get around this by making dma_alloc_coherent() put the ring buffer
in the SRAM attached to the PCI bridge rather than in the SDRAM.

11 years agomn10300: insert PCI root bus resources for the ASB2305 devel motherboard

mn10300: insert PCI root bus resources for the ASB2305 devel motherboard

Insert PCI root bus resources for the MN10300-based ASB2305 development
kit motherboard.  This is required because the CPU's window onto the PCI
bus address space is considerably smaller than the CPU's full address
space and non-PCI devices lie outside of the PCI window that we might want
to access.

Without this patch, the PCI root bus uses the platform-level bus
resources, and these are then confined to the PCI window, thus making
platform_device_add() reject devices outside of this window.

We also add a reservation for the PCI SRAM region.

Use the generic pci_enable_resources() instead of the arch-specific code.

Unlike this arch-specific code, the generic version:

 - checks PCI_NUM_RESOURCES (11), not 6, resources
 - skips resources that have neither IORESOURCE_IO nor IORESOURCE_MEM set
 - skips ROM resources unless IORESOURCE_ROM_ENABLE is set
 - checks for resource collisions with "!r->parent"
