2011-09-29perf script: Add drop monitor scriptNeil Horman3-0/+78
A while back I created the dropmonitor protocol, which allowed users to get reports of dropped frames communicated to them via a netlink socket. While useful, several people have now asked that I integrate the ability to do drop monitoring with perf, so they don't have to run additional tools. This patch adds a drop monitor script to the perf suite, and provides the same output that the netlink socket does.

2011-09-21XZ: Fix incorrect XZ_BUF_ERRORLasse Collin1-7/+20
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: Lasse Collin <[email protected]> Cc: stable <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

2011-09-21init: carefully handle loglevel option on kernel cmdline.Alexander Sverdlin1-2/+13
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.

2011-09-21make /proc/$pid/numa_maps gather_stats() take variable page sizeDave Hansen1-10/+11
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...

2011-09-21xfrm: Perform a replay check after return from async codepathsSteffen Klassert1-0/+5
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.

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.

2011-09-20ppp_generic: fix multilink fragment MTU calculation (again)Henry Wong1-1/+6
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: Henry Wong <[email protected]> Signed-off-by: David S. Miller <[email protected]>

The name_len variable in CIFSFindNext is a signed int that gets set to the resume_name_len in the cifs_search_info. The resume_name_len however is unsigned and for some infolevels is populated directly from a 32 bit value sent by the server. If the server sends a very large value for this, then that value could look negative when converted to a signed int. That would make that value pass the PATH_MAX check later in CIFSFindNext. The name_len would then be used as a length value for a memcpy. It would then be treated as unsigned again, and the memcpy scribbles over a ton of memory.
