tcp: Change possible SYN flooding messages

"Possible SYN flooding on port xxxx " messages can fill logs on servers.

Change logic to log the message only once per listener, and add two new
SNMP counters to track :

TCPReqQFullDoCookies : number of times a SYNCOOKIE was replied to client

TCPReqQFullDrop : number of times a SYN request was dropped because
syncookies were not enabled.

Based on a prior patch from Tom Herbert, and suggestions from David.

sendmmsg/sendmsg: fix unsafe user pointer access

Dereferencing a user pointer directly from kernel-space without going
through the copy_from_user family of functions is a bad idea. Two of
such usages can be found in the sendmsg code path called from sendmmsg,
added by

commit c71d8ebe7a4496fb7231151cb70a6baa0cb56f9a upstream.
commit 5b47b8038f183b44d2d8ff1c7d11a5c1be706b34 in the 3.0-stable tree.

Usages are performed through memcmp() and memcpy() directly. Fix those
by using the already copied msg_sys structure instead of the __user *msg
structure. Note that msg_sys can be set to NULL by verify_compat_iovec()
or verify_iovec(), which requires additional NULL pointer checks.

7 years agoarp: fix rcu lockdep splat in arp_process()
Eric Dumazet [Mon, 22 Aug 2011 19:32:42 +0000]
arp: fix rcu lockdep splat in arp_process()

Dave Jones reported a lockdep splat triggered by an arp_process() call
from parp_redo().

Commit faa9dcf793be (arp: RCU changes) is the origin of the bug, since
it assumed arp_process() was called under rcu_read_lock(), which is not
true in this particular path.

Instead of adding rcu_read_lock() in parp_redo(), I chose to add it in
neigh_proxy_process() to take care of IPv6 side too.

x86-32, vdso: On system call restart after SYSENTER, use int $0x80

When we enter a 32-bit system call via SYSENTER or SYSCALL, we shuffle
the arguments to match the int $0x80 calling convention.  This was
probably a design mistake, but it's what it is now.  This causes
errors if the system call as to be restarted.

For SYSENTER, we have to invoke the instruction from the vdso as the
return address is hardcoded.  Accordingly, we can simply replace the
jump in the vdso with an int $0x80 instruction and use the slower
entry point for a post-restart.

7 years agowl12xx: Fix validation of pm_runtime_get_sync return value

wl12xx: Fix validation of pm_runtime_get_sync return value

wl1271_sdio_power_on checks if the return value of pm_runtime_get_sync
is non-zero, and if so bails out.
However, pm_runtime_get_sync can return a positive number which does not
suggest an error has occurred. This is problematic for two reasons:

1. The function will needlessly bail out without decrementing back the
   runtime PM reference counter.
2. wl1271_power_on only checks if wl1271_power_on return value is
   negative. This means that wl1271_power_on will continue even if
   wl1271_sdio_power_on bailed out. As a result, sdio transactions will
   be initiated without properly enabling the sdio function and claiming
   the host. This could even lead to a kernel panic.

Fix this by only checking that the return value of pm_runtime_get_sync
is non-negative.

wl12xx: Remove obsolete testmode NVS push command

The testmode NVS push command is no longer in use. In addition, it has
several implementation issues that prevent it from working correctly:

1. wl1271_tm_cmd_configure relies on wl->chip.id being set. However,
   since the device was not necessarily booted by the time the function
   is called, wl->chip.id will be initialized to 0.
2. The NVS file is fetched by calling request_firmware() before it is
   possible to push an NVS file.
3. The maximum allowed size of nl binary payloads is not sufficient for
   pushing NVS files.
4. Pushing 128x NVS files will always fail due to a bug in the
   validation code.
5. In case the pushed NVS file is found invalid, the mutex will be kept
   locked and the nvs member will become a dangling pointer.

Since this feature is not being used, remove it completely instead of
fixing it.

7 years agoRevert "irq: Always set IRQF_ONESHOT if no primary handler is specified"
Linus Torvalds [Tue, 23 Aug 2011 17:36:51 +0000]
Revert "irq: Always set IRQF_ONESHOT if no primary handler is specified"

This reverts commit f3637a5f2e2eb391ff5757bc83fb5de8f9726464.

It turns out that this breaks several drivers, one example being OMAP
boards which use the on-board OMAP UARTs and the omap-serial driver that
will not boot to userspace after the commit.

Paul Walmsley reports that enabling CONFIG_DEBUG_SHIRQ reveals 'IRQ
handler type mismatch' errors:

  IRQ handler type mismatch for IRQ 74
  current handler: serial idle
  ...

and the reason is that setting IRQF_ONESHOT will now result in those
interrupt handlers having different IRQF flags, and thus being
unsharable.  So the commit log in the reverted commit:

                            "Since it is required for those users and
    there is no difference for others it makes sense to add this flag
    unconditionally."

is simply not true: there may not be any difference from a "actions at
irq time", but there is a *big* difference wrt this flag testing irq
management (see __setup_irq() in kernel/irq/manage.c).

One solution may be to stop verifying IRQF_ONESHOT in __setup_irq(), but
right now the safe course of action is to revert the change.  Let's
revisit this in a later merge window.

ath9k_hw: Fix STA (AR9485) bringup issue due to incorrect MAC address

Due to some recent optimization done in the way the mac address
bytes are written into the OTP memory, some AR9485 chipsets were
forced to use the first byte from the eeprom template and the
remaining bytes are read from OTP.

AR9485 happens to use generic eeprom template which has 0x1 as
the first byte causes issues in bringing up the card.

So fixed the eeprom template accordingly to address the issue.

Input: ad714x - read the interrupt status registers in a row

The interrupt status registers should be read in row to avoid invalid data.

Alter "read" method for both bus options to allow reading several registers
in a row and make sure we read interrupt status registers properly.

Read sequence saves 50% of bus transactions compared to single register
reads. So use it also for the result registers, which are also located
in a row.

Also update copyright notice.

This change replaced the SMP operations with event based handlers without
taking into account that this only works when the hypervisor supports

sparc: Allow handling signals when stack is corrupted.

If we can't push the pending register windows onto the user's stack,
we disallow signal delivery even if the signal would be delivered on a
valid seperate signal stack.

Add a register window save area in the signal frame, and store any
unsavable windows there.

On sigreturn, if any windows are still queued up in the signal frame,
try to push them back onto the stack and if that fails we kill the
process immediately.

Takashi Iwai [Sat, 20 Aug 2011 07:14:45 +0000]
ALSA: hda - Don't spew too many ELD errors

Currently HD-audio driver shows the all error ELD byte as an error
in the kernel message.  This is annoying when the video driver doesn't
set the correct ELD from the beginning. e.g. radeon sends a zero-byte
data, but we still check ELD with the fixed 128 byte as a workaround
for some broken devices, it spews 128-times errors.

For avoiding this, the driver aborts reading when the first byte is
invalid.  In such a case, the whole data is certainly invalid.

Jiaying Zhang [Fri, 19 Aug 2011 23:13:32 +0000]
ext4: flush any pending end_io requests before DIO reads w/dioread_nolock

There is a race between ext4 buffer write and direct_IO read with
dioread_nolock mount option enabled. The problem is that we clear
PageWriteback flag during end_io time but will do
uninitialized-to-initialized extent conversion later with dioread_nolock.
If an O_direct read request comes in during this period, ext4 will return
zero instead of the recently written data.

This patch checks whether there are any pending uninitialized-to-initialized
extent conversion requests before doing O_direct read to close the race.
Note that this is just a bandaid fix. The fundamental issue is that we
clear PageWriteback flag before we really complete an IO, which is
problem-prone. To fix the fundamental issue, we may need to implement an
extent tree cache that we can use to look up pending to-be-converted extents.

7 years agodrm/i915: set GFX_MODE to pre-Ivybridge default value even on Ivybridge
Jesse Barnes [Fri, 12 Aug 2011 22:28:32 +0000]
drm/i915: set GFX_MODE to pre-Ivybridge default value even on Ivybridge

Prior to Ivybridge, the GFX_MODE would default to 0x800, meaning that
MI_FLUSH would flush the TLBs in addition to the rest of the caches
indicated in the MI_FLUSH command.  However starting with Ivybridge, the
register defaults to 0x2800 out of reset, meaning that to invalidate the
TLB we need to use PIPE_CONTROL.  Since we're not doing that yet, go
back to the old default so things work.
