e8105903d7 powerpc: Fix DEBUG_HIGHMEM build break from d451564669
Code was added to mm/higmem.c that depends on several
kmap types that powerpc does not support.  We add dummy
invalid definitions for KM_NMI, KM_NM_PTE, and KM_IRQ_PTE.

According to list discussion, this fix should not be needed
anymore starting with 2.6.33.  The code is commented to this
effect so hopefully we will remember to remove this.

199bc9ff5c jffs2: Fix memory corruption in jffs2_read_inode_range()
In 2.6.23 kernel, commit a32ea1e1f9
("Fix read/truncate race") fixed a race in the generic code, and as a
side effect, now do_generic_file_read() can ask us to readpage() past
the i_size. This seems to be correctly handled by the block routines
(e.g. block_read_full_page() fills the page with zeroes in case if
somebody is trying to read past the last inode's block).

JFFS2 doesn't handle this; it assumes that it won't be asked to read
pages which don't exist -- and thus that there will be at least _one_
valid 'frag' on the page it's being asked to read. It will fill any
holes with the following memset:

  memset(buf, 0, min(end, frag->ofs + frag->size) - offset);

When the 'closest smaller match' returned by jffs2_lookup_node_frag() is
actually on a previous page and ends before 'offset', that results in:

  memset(buf, 0, <huge unsigned negative>);

Hopefully, in most cases the corruption is fatal, and quickly causing
random oopses, like this:

  root@10.0.0.4:~/ltp-fs-20090531# ./testcases/kernel/fs/ftest/ftest01

This patch fixes the issue, plus fixes all LTP tests on NAND/UBI with
JFFS2 filesystem that were failing since 2.6.23 (seems like the bug
above also broke the truncation).

and other parts were already present in the original

  Author: Ron Rindjunsky <ron.rindjunsky@intel.com>
  Date:   Mon Jan 28 14:07:22 2008 +0200

      mac80211: A-MPDU Tx add delBA from recipient support

The first problem is that I moved a BUG_ON before various
checks -- thereby making it possible to hit. As the comment
indicates, the BUG_ON can be removed since the ampdu_action
callback must already exist when the state is != IDLE.

The second problem isn't easily exploitable but there's a
race condition due to unconditionally setting the state to
OPERATIONAL when a delBA frame is received, even when no
aggregation session was ever initiated. All the drivers
accept stopping the session even then, but that opens a
race window where crashes could happen before the driver
accepts it. Right now, a WARN_ON may happen with non-HT
drivers, while the race opens only for HT drivers.

For this case, there are two things necessary to fix it:
 1) don't process spurious delBA frames, and be more careful
    about the session state; don't drop the lock

 2) HT drivers need to be prepared to handle a session stop
    even before the session was really started -- this is
    true for all drivers (that support aggregation) but
    iwlwifi which can be fixed easily. The other HT drivers
    (ath9k and ar9170) are behaving properly already.

The problem is that the BUG_ON moved before the various

As the comment indicates, the BUG_ON can be removed since
the ampdu_action callback must already exist when the

A similar code path leads to a WARN_ON in
ieee80211_stop_tx_ba_session, which can also be removed.

33a932d143 parisc: fix unwind with recent gcc versions
kernel unwinding is broken with gcc >= 4.x.  Part of the problem is that
binutils seems very sensitive to where the unwind information is stored.

0cae200eec b44: Fix wedge when using netconsole.
Fixes kernel bugzilla #14691

Due to the way netpoll works, it is perfectly legal to see
NAPI already scheduled when new device events are pending
in b44_interrupt().

So logging a message about it is wrong and in fact harmful.

Based upon a patch by Andreas Mohr.

3c91c7ae84 ep93xx-eth: check for zero MAC address on probe, not on device open
If we happen to have registered the driver without passing
a MAC address, we will print a zero MAC address and register
the interface with this invalid address, this is confusin. This
patch moves the checking of a valid ethernet address and the
generation of a random one down from the open function to
the probe function.

d5ccd67bb7 NET: smc91x: Fix irq flags
smc91x.h defines SMC_IRQ_FLAGS to be -1 when it wants the interrupt
flags to be taken from the resource structure.  However, d280ead
changed this to checking for non-zero resource flags.

Unfortunately, this means that on some platforms, we end up passing
'-1' to request_irq rather than the desired result.  Combine the two
conditions into one so that the IRQ flags are taken from the resource
if either SMC_IRQ_FLAGS is -1 or the resource flags specify an
interrupt trigger.

This restores network on at least the Versatile platform.

cc098dc705 r8169: restore mac addr in rtl8169_remove_one and rtl_shutdown
The newer chipsets (all PCI-E) are known that they need full power cycle
(AC or battery removal) to reset MAC address to a  hardwired one. Previous
patch to address this problem loads the original MAC address from EEPROM.
But it brought other problem for which it is necessary to introduce a new
module parameter.
However, it might suffice to restore the initial MAC address before
shutdown/reboot/kexec and when removing the module.

bbf31bf18d ipv4: additional update of dev_net(dev) to struct *net in ip_fragment.c, NULL ptr OOPS
ipv4 ip_frag_reasm(), fully replace 'dev_net(dev)' with 'net', defined
previously patched into 2.6.29.

Between 2.6.28.10 and 2.6.29, net/ipv4/ip_fragment.c was patched,
changing from dev_net(dev) to container_of(...).  Unfortunately the goto
section (out_fail) on oversized packets inside ip_frag_reasm() didn't
get touched up as well.  Oversized IP packets cause a NULL pointer
dereference and immediate hang.

I discovered this running openvasd and my previous email on this is
titled:  NULL pointer dereference at 2.6.32-rc8:net/ipv4/ip_fragment.c:566

This adds support for the SFC9000 family of 10G Ethernet controllers
and LAN-on-motherboard chips, starting with the SFL9021 'Siena' and
SFC9020 'Bethpage'.

The SFC9000 family is based on the SFC4000 'Falcon' architecture, but
with some significant changes:

- Two ports are associated with two independent PCI functions
  (except SFC9010)
- Integrated 10GBASE-T PHY(s) (SFL9021/9022)
- MAC, PHY and board peripherals are managed by firmware
  - Driver does not require board-specific code
  - Firmware supports wake-on-LAN and lights-out management through NC-SI
- IPv6 checksum offload and RSS
- Filtering by MAC address and VLAN (not included in this code)
- PCI SR-IOV (not included in this code)
