2010-03-30iwlwifi: don't include iwl-dev.h from iwl-devtrace.hTejun Heo3-1/+3
iwl-devtrace.h is used to declare and define trace points and including iwl-dev.h from the file, which in turn includes other generic headers, can lead to problems like generating duplicate copies of generic trace points depending on the order of includes. Don't include iwl-dev.h from iwl-devtrace.h but include it from its users - iwl-io.h and iwl-devtrace.c.

2010-03-30x86: don't include slab.h from arch/x86/include/asm/pgtable_32.hTejun Heo1-1/+0
Including slab.h from x86 pgtable_32.h creates a troublesome dependency chain w/ ftrace enabled. The following chain leads to inclusion of pgtable_32.h from define_trace.h. trace/define_trace.h trace/ftrace.h linux/ftrace_event.h linux/ring_buffer.h linux/mm.h asm/pgtable.h asm/pgtable_32.h slab.h itself defines trace hooks via linux/sl[aou]b_def.h linux/kmemtrace.h trace/events/kmem.h If slab.h is not included before define_trace.h is included, this leads to duplicate definitions of kmemtrace hooks or other include dependency problems. pgtable_32.h doesn't need slab.h to begin with. Don't include it from there.

2010-03-30ext3: fix broken handling of EXT3_STATE_NEWLinus Torvalds4-6/+8
In commit 9df93939b735 ("ext3: Use bitops to read/modify EXT3_I(inode)->i_state") ext3 changed its internal 'i_state' variable to use bitops for its state handling. However, unline the same ext4 change, it didn't actually change the name of the field when it changed the semantics of it. As a result, an old use of 'i_state' remained in fs/ext3/ialloc.c that initialized the field to EXT3_STATE_NEW. And that does not work _at_all_ when we're now working with individually named bits rather than values that get masked. So the code tried to mark the state to be new, but in actual fact set the field to EXT3_STATE_JDATA. Which makes no sense at all, and screws up all the code that checks whether the inode was newly allocated. In particular, it made the xattr code unhappy, and caused various random behavior, like apparently https://bugzilla.redhat.com/show_bug.cgi?id=577911 So fix the initialization, and rename the field to match ext4 so that we don't have this happen again.

2010-03-30r8169: offical fix for CVE-2009-4537 (overlength frame DMAs)Neil Horman1-5/+24
Official patch to fix the r8169 frame length check error. Based on this initial thread: http://marc.info/?l=linux-netdev&m=126202972828626&w=1 This is the official patch to fix the frame length problems in the r8169 driver. As noted in the previous thread, while this patch incurs a performance hit on the driver, its possible to improve performance dynamically by updating the mtu and rx_copybreak values at runtime to return performance to what it was for those NICS which are unaffected by the ideosyncracy (if there are any). Summary: A while back Eric submitted a patch for r8169 in which the proper allocated frame size was written to RXMaxSize to prevent the NIC from dmaing too much data. This was done in commit fdd7b4c3302c93f6833e338903ea77245eb510b4. A long time prior to that however, Francois posted 126fa4b9ca5d9d7cb7d46f779ad3bd3631ca387c, which expiclitly disabled the MaxSize setting due to the fact that the hardware behaved in odd ways when overlong frames were received on NIC's supported by this driver. This was mentioned in a security conference recently: http://events.ccc.de/congress/2009/Fahrplan//events/3596.en.html It seems that if we can't enable frame size filtering, then, as Eric correctly noticed, we can find ourselves DMA-ing too much data to a buffer, causing corruption. As a result is seems that we are forced to allocate a frame which is ready to handle a maximally sized receive. This obviously has performance issues with it, so to mitigate that issue, this patch does two things: 1) Raises the copybreak value to the frame allocation size, which should force appropriately sized packets to get allocated on rx, rather than a full new 16k buffer. 2) This patch only disables frame filtering initially (i.e., during the NIC open), changing the MTU results in ring buffer allocation of a size in relation to the new mtu (along with a warning indicating that this is dangerous). Because of item (2), individuals who can't cope with the performance hit (or can otherwise filter frames to prevent the bug), or who have hardware they are sure is unaffected by this issue, can manually lower the copybreak and reset the mtu such that performance is restored easily.

2010-03-30sparc64: Properly truncate pt_regs framepointer in perf callback.David S. Miller1-1/+1
For 32-bit processes, we save the full 64-bits of the regs in pt_regs. But unlike when the userspace actually does load and store instructions, the top 32-bits don't get automatically truncated by the cpu in kernel mode (because the kernel doesn't execute with PSTATE_AM address masking enabled). So we have to do it by hand. Reported-by: Frederic Weisbecker <fweisbec@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-03-28bonding: fix broken multicast with round-robin modeAndy Gospodarek1-8/+32
Round-robin (mode 0) does nothing to ensure that any multicast traffic originally destined for the host will continue to arrive at the host when the link that sent the IGMP join or membership report goes down. One of the benefits of absolute round-robin transmit. Keeping track of subscribed multicast groups for each slave did not seem like a good use of resources, so I decided to simply send on the curr_active slave of the bond (typically the first enslaved device that is up). This makes failover management simple as IGMP membership reports only need to be sent when the curr_active_slave changes. I tested this patch and it appears to work as expected.

2010-03-27igbvf: do not modify tx_queue_len on link speed changeEmil Tantilov2-11/+1
Previously the driver tweaked txqueuelen to avoid false Tx hang reports seen at half duplex. This had the effect of overriding user set values on link change/reset. Testing shows that adjusting only the timeout factor is sufficient to prevent Tx hang reports at half duplex.

2010-03-27ipv4: Restart rt_intern_hash after emergency rebuild (v2)Pavel Emelyanov1-6/+11
The the rebuild changes the genid which in turn is used at the hash calculation. Thus if we don't restart and go on with inserting the rt will happen in wrong chain. (Fixed Neil's comment about the index passed into the rt_intern_hash) Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Reviewed-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: David S.

2010-03-27ipv4: Cleanup struct net dereference in rt_intern_hashPavel Emelyanov1-2/+2
There's no need in getting it 3 times and gcc isn't smart enough to understand this himself. This is just a cleanup before the fix (next patch). Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-03-27net: fix netlink address dumping in IPv4/IPv6Patrick McHardy2-2/+2
When a dump is interrupted at the last device in a hash chain and then continued, "idx" won't get incremented past s_idx, so s_ip_idx is not reset when moving on to the next device. This means of all following devices only the last n - s_ip_idx addresses are dumped. Tested-by: Pawel Staszewski <pstaszewski@itcare.pl> Signed-off-by: Patrick McHardy <kaber@trash.net>
