* | x25: Prevent skb overreads when checking call user dataMatthew Daley2011-10-181-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | x25_find_listener does not check that the amount of call user data given in the skb is big enough in per-socket comparisons, hence buffer overreads may occur. Fix this by adding a check.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are multiple locations in the X.25 packet layer where a skb is assumed to be of at least a certain size and that all its data is currently available at skb->data. These assumptions are not checked, hence buffer overreads may occur. Use pskb_may_pull to check these minimal size assumptions and ensure that data is available at skb->data when necessary, as well as use skb_copy_bits where needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | X.25 call user data is being copied in its entirety from incoming messages without consideration to the size of the destination buffers, leading to possible buffer overflows.

It appears this issue was noticed some time ago, however nothing seemed to come of it: see http://www.spinics.net/lists/linux-x25/msg00043.html and commit 8db09f26f912f7c90c764806e804b558da520d4f.

* | udplite: fast-path computation of checksum coverageGerrit Renker2011-10-181-32/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 903ab86d195cca295379699299c5fc10beba31c7 of 1 March this year ("udp: Add lockless transmit path") introduced a new fast TX path that broke the checksum coverage computation of UDP-lite, which so far depended on up->len (only set if the socket is locked and 0 in the fast path). Fixed by providing both fast- and slow-path computation of checksum coverage. The latter can be removed when UDP(-lite)v6 also uses a lockless transmit path.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The w83627ehf driver is improperly reporting thermal diode sensors as type 2, instead of 3. This caused "sensors" and possibly other monitoring tools to report these sensors as "transistor" instead of "thermal diode". Furthermore, diode subtype selection (CPU vs. external) is only supported by the original W83627EHF/EHG. All later models only support CPU diode type, and some (NCT6776F) don't even have the register in question so we should avoid reading from it.

Revert back to use a kthread per filesystem which fixes all the above issues at the cost of having a task struct and stack around for each mounted filesystem. In addition this also gives us much better ways to diagnose any issues involving hung AIL pushing and removes a small amount of code.

On PPC, this meant it was being swapped to LE and then swapped back to BE while writing to the register. But in the blue frame case, it was being written as LE to the descriptor. The fix is not to swap doorbell unconditionally, write it to the register as BE and convert it to BE when writing it to the descriptor.

But there is a concurrent truncate in the middle of the defrag, it might end up defragging the same range over and over again. The problem is that writepage won't go through and do anything on pages past i_size, so the cow won't happen, so the file will appear to still be fragmented. defrag will end up hitting the same extents again and again. In the worst case, the truncate can actually live lock with the defrag because the defrag keeps creating new ordered extents which the truncate code keeps waiting on. The fix here is to make defrag check for i_size inside the main loop, instead of just once before the looping starts. Signed-off-by: Chris Mason <chris.mason@oracle.com>

| | * | | | | ARM: OMAP4: MMC: fix power and audio issue, decouple USBC1 from MMC1Bryan Buckley2011-09-301-8/+4

This is in accordance with the control module programming guide. This fixes a bug where if trying to use gpio_98 or gpio_99 and MMC1 at the same time the GPIO signal will be affected by a changing SDMMC1_VDDS. Software must keep MMC1_PBIAS cell and MMC1_IO cell PWRDNZ signals low whenever SDMMC1_VDDS ramps up/down or changes for cell protection purposes. MMC1 is based on SDMMC1_VDDS whereas USBC1 is based on SIM_VDDS therefore they can operate independently.

The work he has done so far is excellent, and the fact that he works for Nvidia means he has long-term interest in the platform. Erik Gilling did an astounding amount of work on getting things up and running but has been a silent partner on the maintainership side for a while, and is stepping down. Thanks for your contributions so far, Erik. Finally, update the git URL since I'll take over running the main repo for a while. Overall maintainership model isn't changing much at this time: We'll all three review patches as appropriate, and one of us will collect the main repo (me at this time).

When icmp packets with wrong checksum pass through the octeon net driver, the not_IP, IP_exc, L4_error hardware indicators show no error. so the driver sets CHECKSUM_UNNECESSARY on skb->ip_summed. L4_error only works for TCP/UDP, not for ICMP.
