commit 5b76d060 upstream. Under heavy load (flood ping) it is possible for the MDIO timeout to expire before the loop checks the GO bit again. This patch adds an additional check whether the operation was done before actually returning -ETIMEDOUT. To reproduce this bug, flood ping the device, e.g., ping -f -l 1000 After some time, a "timed out waiting for user access" warning may appear. And even worse, link may go down since the PHY reported a timeout. Signed-off-by:

commit 3066616c upstream. A rather annoying and common case is when booting a PVonHVM guest and exposing the PV KBD and PV VFB - as broken toolstacks don't always initialize the backends correctly. Normally The HVM guest is using the VGA driver and the emulated keyboard for this (though upstream version of QEMU implements PV KBD, but still uses a VGA driver). We provide a very basic two-stage wait mechanism - where we wait for 30 seconds for all devices, and then for 270 for all them except the two mentioned. That allows us to wait for the essential devices, like network or disk for the full 6 minutes. To trigger this, put this in your guest config: vfb = [ 'vnc=1, vnclisten=0.0.0.0 ,vncunused=1'] instead of this: vnc=1 vnclisten="0.0.0.0" Acked-by:

commit e8e937be upstream. Since we are using the m2p_override we do have struct pages corresponding to the user vma mmap'ed by gntdev. Removing the VM_PFNMAP flag makes get_user_pages work on that vma. An example test case would be using a Xen userspace block backend (QDISK) on a file on NFS using O_DIRECT. Signed-off-by:

[Patch not needed upstream as this is a backport build bugfix - gregkh gcc correctly complains: util/hist.c: In function ‘__hists__add_entry’: util/hist.c:240:27: error: invalid type argument of ‘->’ (have ‘struct hist_entry’) util/hist.c:241:23: error: invalid type argument of ‘->’ (have ‘struct hist_entry’) for this new code: + if (he->ms.map != entry->ms.map) { + he->ms.map = entry->ms.map; + if (he->ms.map) + he->ms.map->referenced = true; + } because "entry" is a "struct hist_entry", not a pointer to a struct. In mainline, "entry" is a pointer to struct passed as argument to the function. So this is broken during backporting. But obviously not compile tested.

commit cd94154c upstream. Git commit 36409f63 "use generic RCU page-table freeing code" introduced a tlb flushing bug. Partially revert the above git commit and go back to s390 specific page table flush code. For s390 the TLB can contain three types of entries, "normal" TLB page-table entries, TLB combined region-and-segment-table (CRST) entries and real-space entries. Linux does not use real-space entries which leaves normal TLB entries and CRST entries. The CRST entries are intermediate steps in the page-table translation called translation paths. For example a 4K page access in a three-level page table setup will create two CRST TLB entries and one page-table TLB entry. The advantage of that approach is that a page access next to the previous one can reuse the CRST entries and needs just a single read from memory to create the page-table TLB entry. The disadvantage is that the TLB flushing rules are more complicated, before any page-table may be freed the TLB needs to be flushed. In short: the generic RCU page-table freeing code is incorrect for the CRST entries, in particular the check for mm_users < 2 is troublesome. This is applicable to 3.0+ kernels. Signed-off-by:

commit a09d431f upstream. When the force changes went in back in 3.3.0, we ended up returning disconnected in the !force case, and the connected in when forced, as it hit the hardcoded check. Fix it so all exits go via the hardcoded check and stop spurious modesets on platforms with hardcoded EDIDs. Reported-by: Evan McNabb (Red Hat) Reviewed-by:

commit e3632507 upstream. The check of the encoder type in the commit [e00e8b5e: drm/radeon/kms: fix analog load detection on DVI-I connectors] is obviously wrong, and it's the culprit of the regression on my workstation with DVI-analog connection resulting in the blank output.

commit bdbb776f upstream. It was possible to extract the robust list head address from a setuid process if it had used set_robust_list(), allowing an ASLR info leak. This changes the permission checks to be the same as those used for similar info that comes out of /proc. Running a setuid program that uses robust futexes would have had: cred->euid != pcred->euid cred->euid == pcred->uid so the old permissions check would allow it. I'm not aware of any setuid programs that use robust futexes, so this is just a preventative measure. (This patch is based on changes from grsecurity.) Signed-off-by:

commit afbaa90b upstream. If a bitmap is added while the array is active, it is possible for bitmap_daemon_work to run while the bitmap is being initialised. This is particularly a problem if bitmap_daemon_work sees bitmap->filemap as non-NULL before it has been filled in properly. So hold bitmap_info.mutex while filling in ->filemap to prevent problems. This patch is suitable for any -stable kernel, though it might not apply cleanly before about 3.1. Signed-off-by:

commit c43f1508 upstream. Currently, executing suspend/hibernation, memory access violation occurs. In pch_dma_save_regs() called by suspend(), you can see the following code. static void pch_dma_save_regs(struct pch_dma *pd) { snip... list_for_each_entry_safe(chan, _c, &pd->dma.channels, device_node) { pd_chan = to_pd_chan(chan); pd->ch_regs[i].dev_addr = channel_readl(pd_chan, DEV_ADDR); pd->ch_regs[i].mem_addr = channel_readl(pd_chan, MEM_ADDR); pd->ch_regs[i].size = channel_readl(pd_chan, SIZE); pd->ch_regs[i].next = channel_readl(pd_chan, NEXT); i++; } } Max loop count is 12 defined at pci_table. So, this caused memory access violation. This patch fixes the issue - Modify array size (MAX_CHAN_NR) Signed-off-by:

commit 0b052f4a upstream. Currently, Mode-Control register is accessed by read-modify-write. According to DMA hardware specifications datasheet, prohibits this method. Because this register resets to 0 by DMA HW after DMA transfer completes. Thus, current read-modify-write processing can cause unexpected behavior. The datasheet says in case of writing Mode-Control register, set the value for only target channel, the others must set '11b'. e.g. Set DMA0=01b DMA11=10b CTL0=33333331h CTL2=00002333h NOTE: CTL0 includes DMA0~7 Mode-Control register. CTL2 includes DMA8~11 Mode-Control register. This patch modifies the issue. Signed-off-by:

commit 64d91cfa upstream. Currently, ".setup" function is not set. As a result, when detecting our IOH's uart device without pch_uart, kernel panic occurs at the following of pciserial_init_ports(). for (i = 0; i < nr_ports; i++) { if (quirk->setup(priv, board, &serial_port, i)) break; So, this patch adds the ".setup" function. We can use pci_default_setup because our IOH's uart is compatible with 16550. Signed-off-by:

commit 83331040 upstream. ISSUE: USB Suspend interrupts occur frequently. CAUSE: When it is called pch_udc_reconnect() in USB Suspend, it repeats reset and Suspend. SOLUTION: pch_udc_reconnect() does not enable all interrupts. When an enumeration event occurred the driver enables all interrupts. Signed-off-by:

commit 1c575d2d upstream. ISSUE: After a USB cable is connect/disconnected, the system rarely freezes. CAUSE: Since the USB device controller cannot know to disconnect the USB cable, when it is used without detecting VBUS by GPIO, the UDC driver does not notify to USB Gadget. Since USB Gadget cannot know to disconnect, a false setting occurred when the USB cable is connected/disconnect repeatedly. Signed-off-by:

commit c802672c upstream. ISSUE: If the return value of pch_udc_pcd_init() is False, the return value of this function is unsettled. Since pch_udc_pcd_init() always returns 0, there is not actually the issue. CAUSE: If pch_udc_pcd_init() is True, the variable, retval, is not set for an appropriate value. Signed-off-by:

commit 9914a0de upstream. Currently, external ROM access is enabled/disabled in probe()/remove(). So, when a buggy software access unanticipated memory area, in case of enabling this ADE bit, external ROM memory area can be broken. This patch enables the ADE bit only accessing external ROM area.
