corrects a critical bug of the GW feature. This bug made all the unicast packets destined to a GW to be sent as broadcast. This bug is present even if the sender GW feature is configured as OFF. It's an urgent bug fix and should be committed as soon as possible. This was a regression introduced by 43676ab5Signed-off-by:

xz_dec_run() could incorrectly return XZ_BUF_ERROR if all of the following was true: - The caller knows how many bytes of output to expect and only provides that much output space. - When the last output bytes are decoded, the caller-provided input buffer ends right before the LZMA2 end of payload marker. So LZMA2 won't provide more output anymore, but it won't know it yet and thus won't return XZ_STREAM_END yet. - A BCJ filter is in use and it hasn't left any unfiltered bytes in the temp buffer. This can happen with any BCJ filter, but in practice it's more likely with filters other than the x86 BCJ. This fixes <https://bugzilla.redhat.com/show_bug.cgi?id=735408> where Squashfs thinks that a valid file system is corrupt. This also fixes a similar bug in single-call mode where the uncompressed size of a block using BCJ + LZMA2 was 0 bytes and caller provided no output space. Many empty .xz files don't contain any blocks and thus don't trigger this bug. This also tweaks a closely related detail: xz_dec_bcj_run() could call xz_dec_lzma2_run() to decode into temp buffer when it was known to be useless. This was harmless although it wasted a minuscule number of CPU cycles. Signed-off-by:

When a malformed loglevel value (for example "${abc}") is passed on the kernel cmdline, the loglevel itself is being set to 0. That then suppresses all following messages, including all the errors and crashes caused by other malformed cmdline options. This could make debugging process quite tricky. This patch leaves the previous value of loglevel if the new value is incorrect and reports an error code in this case. Signed-off-by:

This is modeled after the smaps code. It detects transparent hugepages and then does a single gather_stats() for the page as a whole. This has two benifits: 1. It is more efficient since it does many pages in a single shot. 2. It does not have to break down the huge page. Signed-off-by:

gather_pte_stats() does a number of checks on a target page to see whether it should even be considered for statistics. This breaks that code out in to a separate function so that we can use it in the transparent hugepage case in the next patch. Signed-off-by:

We need to teach the numa_maps code about transparent huge pages. The first step is to teach gather_stats() that the pte it is dealing with might represent more than one page. Note that will we use this in a moment for transparent huge pages since they have use a single pmd_t which _acts_ as a "surrogate" for a bunch of smaller pte_t's. I'm a _bit_ unhappy that this interface counts in hugetlbfs page sizes for hugetlbfs pages and PAGE_SIZE for normal pages. That means that to figure out how many _bytes_ "dirty=1" means, you must first know the hugetlbfs page size. That's easier said than done especially if you don't have visibility in to the mount. But, that's probably a discussion for another day especially since it would change behavior to fix it. But, just in case anyone wonders why this patch only passes a '1' in the hugetlb case...

When asyncronous crypto algorithms are used, there might be many packets that passed the xfrm replay check, but the replay advance function is not called yet for these packets. So the replay check function would accept a replay of all of these packets. Also the system might crash if there are more packets in async processing than the size of the anti replay window, because the replay advance function would try to update the replay window beyond the bounds. This pach adds a second replay check after resuming from the async processing to fix these issues. Signed-off-by:

It seems that at least one PPC machine would occasionally give a (valid) 0 as the return value from dma_map, this caused the ixgbe code to not work correctly. A fix is pending in the PPC tree to not return 0 from dma map, but we can also fix the driver to make sure we don't mess up in other arches as well. This patch is applicable to all current stable kernels. Ref: https://bugzilla.redhat.com/show_bug.cgi?id=683611Reported-by:

commit 92cd3a17 tg3: Simplify tx bd assignments broke VLAN tagging on outbound packets. It ifdef'ed BCM_KERNEL_SUPPORTS_8021Q, but this is not set anywhere. So vlan never gets set, and all packets are sent with vlan=0. v2: We can just remove the test. vlan_tx_tag_present is valid regardless of whether the 802.1q module is built. Tested on BCM5721 rev 11.

After commit c5f5c4db ("staging: zcache: fix crash on high memory swap") cleancache crashes on the first successful get. This was caused by a remaining virt_to_page() call in zcache_pampd_get_data_and_free() that only gets run in the cleancache path. The patch converts the virt_to_page() to struct page casting like was done for other instances in c5f5c4db. Signed-off-by:

The changes introduced in commit cc22b4c1 "ARM: set vga memory base at run-time" Makes the Integrator/AP freeze completely. I appears that this is due to the VGA base address being assigned at PCI init time, while this base is needed earlier than that. Moving the initialization of the base address to the .map_io function solves this problem.

Commit 88491d81(drivers/net: Kconfig & Makefile cleanup) causes a regression that netconsole does not work if netconsole and network device driver are build into kernel, because netconsole is linked before network device driver.

When using MLPPP, the maximum size of a fragment is incorrectly calculated with an offset of -2. This patch reverses the changes in the patch found here: http://marc.info/?l=linux-netdev&m=123541324010539&w=2 The value of hdrlen includes the size of both the 2-byte PPP protocol field and the 2- or 4-byte multilink header (2+4=6 for long sequence numbers, 2+2=4 for short sequence numbers). Section 2 of RFC1661 says that the MRU that is negotiated (i.e., the MTU of the sending system) includes only the PPP payload but not the protocol field, thus the correct MTU should be the link's MTU minus the multilink header (mtu - (hdrlen-2)). The incorrect calculation causes Linux to fragment packets to a size two bytes smaller than the allowed MTU. While not technically illegal, this behaviour confounds MRU-tuning to avoid PPP-layer fragmentation. Signed-off-by:
