2010-01-28partitions: use sector size for EFI GPTKarel Zak
commit 7d13af3279985f554784a45cc961f706dbcdbdd1 upstream. Currently, kernel uses strictly 512-byte sectors for EFI GPT parsing. That's wrong. UEFI standard (version 2.3, May 2009, 5.3.1 GUID Format overview, page 95) defines that LBA is always based on the logical block size. It means bdev_logical_block_size() (aka BLKSSZGET) for Linux. This patch removes static sector size from EFI GPT parser. The problem is reproducible with the latest GNU Parted: # modprobe scsi_debug dev_size_mb=50 sector_size=4096 # ./parted /dev/sdb print Model: Linux scsi_debug (scsi) Disk /dev/sdb: 52.4MB Sector size (logical/physical): 4096B/4096B Partition Table: gpt Number Start End Size File system Name Flags 1 24.6kB 3002kB 2978kB primary 2 3002kB 6001kB 2998kB primary 3 6001kB 9003kB 3002kB primary # blockdev --rereadpt /dev/sdb # dmesg | tail -1 sdb: unknown partition table <---- !!! with this patch: # blockdev --rereadpt /dev/sdb # dmesg | tail -1 sdb: sdb1 sdb2 sdb3 Signed-off-by: Karel Zak <kzak@redhat.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-01-28partitions: read whole sector with EFI GPT headerKarel Zak
commit 87038c2d5bda2418fda8b1456a0ae81cc3ff5bd8 upstream. The size of EFI GPT header is not static, but whole sector is allocated for the header. The HeaderSize field must be greater than 92 (= sizeof(struct gpt_header) and must be less than or equal to the logical block size. It means we have to read whole sector with the header, because the header crc32 checksum is calculated according to HeaderSize.

2010-01-28netfilter: xtables: fix conntrack match v1 ipt-save outputFlorian Westphal
commit 3a0429292daa0e1ec848bd26479f5e48b0d54a42 upstream. commit d6d3f08b0fd998b647a05540cedd11a067b72867 (netfilter: xtables: conntrack match revision 2) does break the v1 conntrack match iptables-save output in a subtle way. Problem is as follows: up = kmalloc(sizeof(*up), GFP_KERNEL); [..] /* * The strategy here is to minimize the overhead of v1 matching, * by prebuilding a v2 struct and putting the pointer into the * v1 dataspace. */ memcpy(up, info, offsetof(typeof(*info), state_mask)); [..] *(void **)info = up; As the v2 struct pointer is saved in the match data space, it clobbers the first structure member (->origsrc_addr). Because the _v1 match function grabs this pointer and does not actually look at the v1 origsrc, run time functionality does not break. But iptables -nvL (or iptables-save) cannot know that v1 origsrc_addr has been overloaded in this way: $ iptables -p tcp -A OUTPUT -m conntrack --ctorigsrc 10.0.0.1 -j ACCEPT $ iptables-save -A OUTPUT -p tcp -m conntrack --ctorigsrc 128.173.134.206 -j ACCEPT (128.173... is the address to the v2 match structure). To fix this, we take advantage of the fact that the v1 and v2 structures are identical with exception of the last two structure members (u8 in v1, u16 in v2). We extract them as early as possible and prevent the v2 matching function from looking at those two members directly.

2010-01-28V4L/DVB (13680b): DocBook/media: create links for included sourcesBen Hutchings
commit 5bf583473813530c1bf82051a35fac8d5045f4f7 upstream. If docs are being built in a separate directory, xmlto and xsltproc can't find included sources. Make links back to the source directory. I would much prefer to have xmlto and xsltproc look in the source directory for included entities but couldn't see how to do that. This needs to be solved in some way for 2.6.32, even if this patch isn't the right way to do it.

commit ea9d8e3f45404d411c00ae67b45cc35c58265bb7 upstream. Marc reported that the BUG_ON in clockevents_notify() triggers on his system. This happens because the kernel tries to remove an active clock event device (used for broadcasting) from the device list. The handling of devices which can be used as per cpu device and as a global broadcast device is suboptimal. The simplest solution for now (and for stable) is to check whether the device is used as global broadcast device, but this needs to be revisited.

2010-01-25vmalloc: remove BUG_ON due to racy counting of VM_LAZY_FREEYongseok Koh
commit 88f5004430babb836cfce886d5d54c82166f8ba4 upstream. In free_unmap_area_noflush(), va->flags is marked as VM_LAZY_FREE first, and then vmap_lazy_nr is increased atomically. But, in __purge_vmap_area_lazy(), while traversing of vmap_are_list, nr is counted by checking VM_LAZY_FREE is set to va->flags. After counting the variable nr, kernel reads vmap_lazy_nr atomically and checks a BUG_ON condition whether nr is greater than vmap_lazy_nr to prevent vmap_lazy_nr from being negative. The problem is that, if interrupted right after marking VM_LAZY_FREE, increment of vmap_lazy_nr can be delayed. Consequently, BUG_ON condition can be met because nr is counted more than vmap_lazy_nr. It is highly probable when vmalloc/vfree are called frequently. This scenario have been verified by adding delay between marking VM_LAZY_FREE and increasing vmap_lazy_nr in free_unmap_area_noflush(). Even the vmap_lazy_nr is for checking high watermark, it never be the strict watermark. Although the BUG_ON condition is to prevent vmap_lazy_nr from being negative, vmap_lazy_nr is signed variable. So, it could go down to negative value temporarily. Consequently, removing the BUG_ON condition is proper. A possible BUG_ON message is like the below. kernel BUG at mm/vmalloc.c:517! invalid opcode: 0000 [#1] SMP EIP: 0060:[<c04824a4>] EFLAGS: 00010297 CPU: 3 EIP is at __purge_vmap_area_lazy+0x144/0x150 EAX: ee8a8818 EBX: c08e77d4 ECX: e7c7ae40 EDX: c08e77ec ESI: 000081fe EDI: e7c7ae60 EBP: e7c7ae64 ESP: e7c7ae3c DS: 007b ES: 007b FS: 00d8 GS: 0033 SS: 0068 Call Trace: [<c0482ad9>] free_unmap_vmap_area_noflush+0x69/0x70 [<c0482b02>] remove_vm_area+0x22/0x70 [<c0482c15>] __vunmap+0x45/0xe0 [<c04831ec>] vmalloc+0x2c/0x30 Code: 8d 59 e0 eb 04 66 90 89 cb 89 d0 e8 87 fe ff ff 8b 43 20 89 da 8d 48 e0 8d 43 20 3b 04 24 75 e7 fe 05 a8 a5 a3 c0 e9 78 ff ff ff <0f> 0b eb fe 90 8d b4 26 00 00 00 00 56 89 c6 b8 ac a5 a3 c0 31 EIP: [<c04824a4>] __purge_vmap_area_lazy+0x144/0x150 SS:ESP 0068:e7c7ae3c [ See also http://marc.info/?l=linux-kernel&m=126335856228090&w=2 ] Signed-off-by: Yongseok Koh <yongseok.koh@samsung.com> Reviewed-by: Minchan Kim <minchan.kim@gmail.com> Cc: Nick Piggin <npiggin@suse.de> Cc: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-01-25USB: fix usbstorage for 2770:915d delivers no FATRyan May
commit 10d2cdb6102669279bee2d9a00a22431b74583d5 upstream. Resolves kernel.org bug 14914. Remove entry for 2770:915d (usb digital camera with mass storage support) from unusual_devs.h. The fix triggered by the entry causes the file system on the camera to be completely inaccessible (no partition table, the device is not mountable). The patch works, but let me clarify a few things about it. All the patch does is remove the entry for this device from the drivers/usb/storage/unusual_devs.h, which is supposed to help with a problem with the device's reported size (I think). I'm pretty sure it was originally added for a reason, so I'm not sure removing it won't cause other problems to reappear. Also, I should note that this unusual_devs.h entry was present (and activating workarounds) in 2.6.29, but in that version everything works fine. Starting with 2.6.30, things no longer work.

commit 6a304caf0bf9c429fc261f260b86cabf5bde2cbb upstream. For some SDVO cards based on conexant chip, we can't read the EDID if we don't read the response after issuing SDVO DDC bus switch command. From the SDVO spec once when another I2C transaction is finished after completing the I2C transaction of issuing the bus switch command, it will be switched back to the SDVO internal state again. So we can't initiate a new I2C transaction to read the response after issuing the DDC bus switch command. Instead we should issue DDC bus switch command and read the response in the same I2C transaction. https://bugs.freedesktop.org/show_bug.cgi?id=23842 https://bugs.freedesktop.org/show_bug.cgi?id=24458 https://bugs.freedesktop.org/show_bug.cgi?id=24522 https://bugs.freedesktop.org/show_bug.cgi?id=24282 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Tested-by: Sebastien Caty <sebastien.caty@mrnf.gouv.qc.ca> Signed-off-by: Eric Anholt <eric@anholt.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2010-01-25USB: add missing delay during remote wakeupAlan Stern
commit 49d0f078f494b9d81e820a13dd8093a9bfb0b6b1 upstream. This patch (as1330) fixes a bug in khbud's handling of remote wakeups. When a device sends a remote-wakeup request, the parent hub (or the host controller driver, for directly attached devices) begins the resume sequence and notifies khubd when the sequence finishes. At this point the port's SUSPEND feature is automatically turned off. However the device needs an additional 10-ms resume-recovery time (TRSMRCY in the USB spec). Khubd does not wait for this delay if the SUSPEND feature is off, and as a result some devices fail to behave properly following a remote wakeup. This patch adds the missing delay to the remote-wakeup path. It also extends the resume-signalling delay used by ehci-hcd and uhci-hcd from 20 ms (the value in the spec) to 25 ms (the value we use for non-remote-wakeup resumes). The extra time appears to help some devices.

commit cec3a53c7fe794237b582e8e77fc0e48465e65ee upstream. This patch (as1321) fixes a problem with EHCI and UHCI root-hub suspends: If the suspend occurs while a port is trying to resume, the resume doesn't finish and simply gets lost. When remote wakeup is enabled, this is undesirable behavior. The patch checks first to see if any port resumes are in progress, and if they are then it fails the root-hub suspend with -EBUSY.

commit 1b9a38bfa6e664ff02511314f5586d711c83cc91 upstream. This patch (as1320) fixes two problems related to interrupt-URB scheduling in ehci-hcd. URBs with an interval of 2 or 4 microframes aren't handled. For the time being, the patch reduces to interval to 1 uframe. URBs are constrained to have an interval no larger than 1024 frames by usb_submit_urb(). But some EHCI controllers allow use of a schedule as short as 256 frames; for these controllers we may have to decrease the interval to the actual schedule length. The second problem isn't very significant since few devices expose interrupt endpoints with an interval larger than 256 frames. But the first problem is critical; it will prevent the kernel from working with devices having interrupt intervals of 2 or 4 uframes.
