commit 87038c2d 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. For more details see UEFI standard (version 2.3, May 2009): - 5.3.1 GUID Format overview, page 93 - Table 13. GUID Partition Table Header, page 96 Signed-off-by:

commit 3a042929 upstream. commit d6d3f08b (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.

commit 5bf58347 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. Signed-off-by:

But recent commit 138d1569 changes the behaviour to don't cond_resched when in_atomic. This makes the sleeping function called from invalid context bug happen again, which is reported in http://lkml.org/lkml/2009/12/1/371.

commit ea9d8e3f 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. [ tglx: restored the cpuweight check and massaged the changelog ] Reported-by:

commit 88f50044 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:

commit 10d2cdb6 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 6a304caf 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=24282Signed-off-by:
