(cherry-picked from commit 34198bf8) There is no guarantee that the old TSS descriptor in the GDT contains the proper base address. This is the case for Windows installation's reboot-via-triplefault. Use guest registers instead. Also translate the address properly.

[ Upstream commit d72609e1 ] Correct sparc64's implementation of FUTEX_OP_ANDN to do a bitwise negate of the oparg parameter before applying the AND operation. All other archs that support FUTEX_OP_ANDN either negate oparg explicitly (frv, ia64, mips, sh, x86), or do so indirectly by using an and-not instruction (powerpc). Since sparc64 has and-not, I chose to use that solution. I've not found any use of FUTEX_OP_ANDN in glibc so the impact of this bug is probably minor. But other user-space components may try to use it so it should still get fixed. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: David S.

[ Upstream commit 77e2f14f ] SCTP used ip6_xmit() to send fragments after received ICMP packet too big message. But while send packet used ip6_xmit, the skb->local_df is not initialized. So when skb if enter ip6_fragment(), the following code will discard the skb. ip6_fragment(...) { if (!skb->local_df) { ... return -EMSGSIZE; } ... } SCTP do the following step: 1. send packet ip6_xmit(skb, ipfragok=0) 2. received ICMP packet too big message 3. if PMTUD_ENABLE: ip6_xmit(skb, ipfragok=1) This patch fixed the problem by set local_df if ipfragok is true.

commit 5c742b45 upstream In the old acer_acpi, I discovered that on some of the newer AMW0 laptops that supported the WMID methods, they don't work properly for setting the wireless and bluetooth values. So for the AMW0 V2 laptops, we want to use both the 'old' AMW0 and the 'new' WMID methods for setting wireless & bluetooth to guarantee we always enable it. This was fixed in acer_acpi some time ago, but I forgot to port the patch over to acer-wmi when it was merged. (Without this patch, early AMW0 V2 laptops such as the Aspire 5040 won't work with acer-wmi, where-as they did with the old acer_acpi).

commit 8ab19ea3 upstream There is a slight chance for a deadlock in the estimator code. We can't call del_timer_sync() while holding our lock, as the timer might be active and spinning for the lock on another cpu. Work around this issue by using try_to_del_timer_sync() and releasing the lock. We could actually delete the timer outside of our lock, as the add and kill functions are only every called from userspace via [gs]etsockopt() and are serialized by a mutex, but better make this explicit.

commit 969830b2 upstream Some chips appear to have the 2D engine hang during screen redraw, typically in a sequence of copyarea operations. This appear to be solved by adding a flush of the engine destination pixel cache and waiting for the engine to be idle before issuing the accel operation. The performance impact seems to be fairly small. Here is a trace on an RV370 (PCI device ID 0x5b64), it records the RBBM_STATUS register, then the source x/y, destination x/y, and width/height used for the copy: ---------------------------------------- radeonfb_prim_copyarea: STATUS[00000140] src[210:70] dst[210:60] wh[a0:10] radeonfb_prim_copyarea: STATUS[00000140] src[2b8:70] dst[2b8:60] wh[88:10] radeonfb_prim_copyarea: STATUS[00000140] src[348:70] dst[348:60] wh[40:10] radeonfb_prim_copyarea: STATUS[80020140] src[390:70] dst[390:60] wh[88:10] radeonfb_prim_copyarea: STATUS[8002613f] src[40:80] dst[40:70] wh[28:10] radeonfb_prim_copyarea: STATUS[80026139] src[a8:80] dst[a8:70] wh[38:10] radeonfb_prim_copyarea: STATUS[80026133] src[e8:80] dst[e8:70] wh[80:10] radeonfb_prim_copyarea: STATUS[8002612d] src[170:80] dst[170:70] wh[30:10] radeonfb_prim_copyarea: STATUS[80026127] src[1a8:80] dst[1a8:70] wh[8:10] radeonfb_prim_copyarea: STATUS[80026121] src[1b8:80] dst[1b8:70] wh[88:10] radeonfb_prim_copyarea: STATUS[8002611b] src[248:80] dst[248:70] wh[68:10] ---------------------------------------- When things are going fine the copies complete before the next ROP is even issued, but all of a sudden the 2D unit becomes active (bit 17 in RBBM_STATUS) and the FIFO retry (bit 13) and FIFO pipeline busy (bit 14) are set as well. The FIFO begins to backup until it becomes full. What happens next is the radeon_fifo_wait() times out, and we access the chip illegally leading to a bus error which usually wedges the box. None of this makes it to the console screen, of course :-) radeon_fifo_wait() should be modified to reset the accelerator when this timeout happens instead of programming the chip anyways. ---------------------------------------- radeonfb: FIFO Timeout !

This will only happen if you 1) VC switch or 2) run "consolechars" or 3) unblank the screen. This seems to happen because until a redraw_screen() the screen scrolling method used by fbcon is not finalized yet. I've seen this with other fb drivers too. So if all you do is boot straight into X you will never see this bug on the relevant chips. Signed-off-by: David S.

commit ba661292 upstream The bug was reported and analysed by Mark McLoughlin <markmc@redhat.com>, the patch is based on his and Roland's suggestions. posix_timer_event() always rewrites the pre-allocated siginfo before sending the signal. Most of the written info is the same all the time, but memset(0) is very wrong. If ->sigq is queued we can race with collect_signal() which can fail to find this siginfo looking at .si_signo, or copy_siginfo() can copy the wrong .si_code/si_tid/etc. In short, sys_timer_settime() can in fact stop the active timer, or the user can receive the siginfo with the wrong .si_xxx values. Move "memset(->info, 0)" from posix_timer_event() to alloc_posix_timer(), change send_sigqueue() to set .si_overrun = 0 when ->sigq is not queued. It would be nice to move the whole sigq->info initialization from send to create path, but this is not easy to do without uglifying timer_create() further. As Roland rightly pointed out, we need more cleanups/fixes here, see the "FIXME" comment in the patch. Hopefully this patch makes sense anyway, and it can mask the most bad implications.

commit ad337591 upstream It seems cdrwtool in the udftools has been unusable on "modern" kernels for some time. A Google search reveals many people with the same issue but no solution (cdrwtool fails to format the disk). After spending some time tracking down the issue, it comes down to the following: The udftools still use the older CDROM_SEND_PACKET interface to send things like FORMAT_UNIT through to the drive. They should really be updated, but that's another story. Since most distros are using libata now, the cd or dvd burner appears as a SCSI device, and we wind up in block/scsi_ioctl.c. Here, the code tries to take the "struct cdrom_generic_command" and translate it and stuff it into a "struct sg_io_hdr" structure so it can pass it to the modern sg_io() routine instead. Unfortunately, there is one error, or rather an omission in the translation. The timeout that is passed in in the "struct cdrom_generic_command" is in HZ=100 units, and this is modified and correctly converted to jiffies by use of clock_t_to_jiffies(). However, a little further down, this cgc.timeout value in jiffies is simply copied into the sg_io_hdr timeout, which should be in milliseconds. Since most modern x86 kernels seems to be getting build with HZ=250, the timeout that is passed to sg_io and eventually converted to the timeout_per_command member of the scsi_cmnd structure is now four times too small. Since cdrwtool tries to set the timeout to one hour for the FORMAT_UNIT command, and it takes about 20 minutes to format a 4x CDRW, the SCSI error-handler kicks in after the FORMAT_UNIT completes because it took longer than the incorrectly-calculated timeout.

When I tested the same on older kernels like 2.6.18, I got the correct result i.e errno 12 (ENOMEM). I think in source code mlock(2), setting errno ENOMEM has been missed in do_mlock() , on mlock_fixup() failure. SUSv3 requires the following behavior frmo mlock(2). [ENOMEM] Some or all of the address range specified by the addr and len arguments does not correspond to valid mapped pages in the address space of the process. [EAGAIN] Some or all of the memory identified by the operation could not be locked when the call was made. This rule isn't so nice and slighly strange. but many people think POSIX/SUS compliance is important.

commit 3a0f2c87 upstream When signal is noisy, hardware can use all RX buffers and since the last entry in the list is self-linked, it overwrites the entry until we link new buffers. Ensure that we don't free this last one until we are 100% sure that it is not used by the hardware anymore to not cause memory curruption as can be seen below. This is done by checking next buffer in the list. Even after that we know that the hardware refetched the new link and proceeded further (the next buffer is ready) we can finally free the overwritten buffer. We discard it since the status in its descriptor is overwritten (OR-ed by new status) too. ============================================================================= BUG kmalloc-4096: Poison overwritten ----------------------------------------------------------------------------- INFO: 0xffff810067419060-0xffff810067419667.

commit d70b67c8 upstream Lookup can install a child dentry for a deleted directory. This keeps the directory dentry alive, and the inode pinned in the cache and on disk, even after all external references have gone away. This isn't a big problem normally, since memory pressure or umount will clear out the directory dentry and its children, releasing the inode. But for UBIFS this causes problems because its orphan area can overflow. Fix this by returning ENOENT for all lookups on a S_DEAD directory before creating a child dentry. Thanks to Zoltan Sogor for noticing this while testing UBIFS, and Artem for the excellent analysis of the problem and testing.

commit d2cd74b1 upstream On Audigy2 Platinum, the Analog/Digital mixer switch is inverted. https://bugzilla.novell.com/show_bug.cgi?id=396204 The patch adds a simple workaround. There might be another device requiring a similar fix, too (or fix for audigy2 generically), but right now I fix only the known broken one.

commit 9ad593f6 upstream Many HD-audio controllers seem inaccurate about the IRQ timing of PCM period updates. This has caused problems on audio quality; e.g. JACK doesn't work with two periods. This patch fixes the problem by checking the current DMA position at IRQ handler and delays the period-update via a workq if it's inaccurate.
