This leads to an infinite loop in ib_umem_get(), since the code boils down to: while (npages) { ret = get_user_pages(...); npages -= ret; } Fix this by taking the minimum as unsigned longs, so that the value of npages is never truncated. The impact of this bug isn't too severe, since the value of npages is checked against RLIMIT_MEMLOCK, so a process would need to have an astronomical limit or have CAP_IPC_LOCK to be able to trigger this, and such a process could already cause lots of mischief. But it does let buggy userspace code cause a kernel lock-up; for example I hit this with code that passes a negative value into a memory registartion function where it is promoted to a huge u64 value.

However, the support was incomplete: the completion structure was not extended with a field for the key contained in incoming send with invalidate requests. Full support for memory management extensions (send with invalidate, local invalidate, fast register through a send queue, etc) is planned for 2.6.27. Since send with invalidate is not very useful by itself, just remove the IB_DEVICE_SEND_W_INV bit before the 2.6.26 final release; we will add an IB_DEVICE_MEM_MGT_EXTENSIONS bit in 2.6.27, which makes things simpler for applications, since they will not have quite as confusing an array of fine-grained bits to check.

When we get a "PS sleep" event, we have to confirm this to the firmware. The confirm happens with a command, but this command is special: the firmware won't send us a response. if_cs_host_to_card() is setting priv->dnld_sent anyway, so this variable stayed at DNLD_DATA_SENT and was never cleared back. Now I put the special knowledge that the CMD_802_11_PS_MODE with CMD_SUBCMD_SLEEP_CONFIRMED doesn't need to need a response by directly clearing the dnld_sent state in lbs_send_confirmsleep().

The problem is that the added flow control check will always fail if flow control is set to autoneg and either RX or TX (or both) flow control is enabled. The driver defaults to setting flow control to autoneg and advertises both RX and TX flow control. The fix is to remove the errant check.

The first problem is that GPIO 0 and GPIO 2 have been swapped. This change prevented the administrator from turning on WOL when it is disabled in NVRAM. The fix is to add a new path for the 5761 that swaps the two GPIOs in the code as well. The second problem is that GPIO 1 could not be toggled by the driver because the GPIO is shared with the debug UART GPIO. This will prevent the administrator from being able to turn WOL off if it was enabled in NVRAM. The fix is to always disable the debug UART after a GRC reset.

Hardware acceleration was removed when the driver was rewritten for the new framebuffer API in 2003. Software rendering requires a different framebuffer access mode but that wasn't changed.

If the queue is full, it then enables interrupts and waits for notification that more work has been performed. However, a side-effect of this scheme is that there are always xmit skbs left dangling when no new packets are sent, against the Documentation/networking/driver.txt guideline: "... it is not allowed for your TX mitigation scheme to let TX packets "hang out" in the TX ring unreclaimed forever if no new TX packets are sent." Add a timer to ensure that any time we queue new TX skbs, we will shortly free them again. This fixes an easily reproduced hang at shutdown where iptables attempts to unload nf_conntrack and nf_conntrack waits for an skb it is tracking to be freed, but virtio_net never frees it.

Due to this bug, there will be oops on AC<->DC on some systems, where they support C-states in one DC and not in AC. The current code does ON BOOT: Look at CST and other C-state info to see whether more than C1 is supported. If it is, then acpi processor_idle does a cpuidle_register_driver() call, which internally enables the device. ON CST change notification (AC<->DC) and on suspend-resume: acpi driver temporarily disables device, updates the device with any new C-states, and reenables the device. The problem is is on boot, there are no C2, C3 states supported and we skip the register. Later on AC<->DC, we may get a CST notification and we try to reevaluate CST and enabled the device, without actually registering it. This causes breakage as we try to create /sys fs sub directory, without the parent directory which is created at register time.

If one is lucky, that illegal write would cause an OOPS, but chances are it would silently corrupt a byte. The problem was introduced in commit af116101, "ACPI: thinkpad-acpi: add sysfs led class support to thinkpad leds (v3.2)". Fix the bug by refactoring the entire code to be far more obvious on what it wants to do. Also do some defensive "constification". Issue reported by Karol Lewandowski (he's an lucky guy and got an OOPS instead of silent corruption :-) ). Root cause of the OOPS identified by Adrian Bunk . Thanks, Adrian!

Some resources have optional fields, so the size of encoded descriptors varies depending on the specific values. For example, IRQ descriptors can be either two or three bytes long. The third byte contains triggering information and can be omitted if the IRQ is edge-triggered and active high. The BIOS often assumes that IRQ descriptors in the _SRS buffer use the same format as those in the _CRS buffer, so this patch enforces that constraint. The "Start Dependent Function" descriptor also has an optional byte, but we don't currently encode those descriptors, so I didn't do anything for those. I have tested this patch on a Toshiba Portege 4000. Without the patch, parport_pc claims the parallel port only if I use "pnpacpi=off". This patch makes it work with PNPACPI.

Miller" Date: Thu, 12 Jun 2008 02:22:02 -0700 Subject: net: Eliminate flush_scheduled_work() calls while RTNL is held. If the RTNL is held when we invoke flush_scheduled_work() we could deadlock. One such case is linkwatch, it is a work struct which tries to grab the RTNL semaphore. The most common case are net driver ->stop() methods. The simplest conversion is to instead use cancel_{delayed_}work_sync() explicitly on the various work struct the driver uses. This is an OK transformation because these work structs are doing things like resetting the chip, restarting link negotiation, and so forth. And if we're bringing down the device, we're about to turn the chip off and reset it anways. So if we cancel a pending work event, that's fine here. Some drivers were working around this deadlock by using a msleep() polling loop of some sort, and those cases are converted to instead use cancel_{delayed_}work_sync() as well.

The patch fixes the problem by creating the platform device for the RTC when PNP is disabled. This may also help running the PNP-enabled kernel on an older PCs.

The problem is that class_find_child would get a reference to the host's class device which is never released. Since the host class device holds a reference to the host gendev, the host can never be freed. In 2.6.26 we started using class_find_device, and this function also gets a reference to the device, so we end up with an extra ref and the host will not get released. This patch adds a put_device to balance the class_find_device() get. I kept the scsi_host_get in scsi_host_lookup, because the target layer is using scsi_host_lookup and it looks like it needs the SHOST_DEL check.

We now have a report of a system fitted with an EEPROM containing all zeros where we expect the MAC address to be, and we currently handle this as an error condition. Turns out, on this system the BIOS writes a valid MAC address to the NIC's MAC Station Address register, but we never try to read it because we return an error when we find the all- zeros address in EEPROM. This patch relaxes the error check and continues looking for a MAC address even if it finds an illegal one in EEPROM.

This hung up the events kernel thread, e.g. locked up keyboard input. https://bugzilla.redhat.com/show_bug.cgi?id=444694 https://bugzilla.redhat.com/show_bug.cgi?id=446763 This problem was introduced between 2.6.25 and 2.6.26-rc1 by commit 2a0a2590498be7b92e3e76409c9b8ee722e23c8f "firewire: wait until PHY configuration packet was transmitted (fix bus reset loop)". The solution is to wait with timeout. I tested it with 7 different working controllers and 1 non-working controller. On the working ones, the packet callback complete()s usually --- but not always --- before a timeout of 10ms. Hence I chose a safer timeout of 100ms. On the few tests with the non-working controller ALi M5271, PHY config packet transmission always timed out so far. (Fw-ohci needs to be fixed for this controller independently of this deadline fix. Often the core doesn't even attempt to send a phy config because not even self ID reception works.)

I think that besides this being a real issue with Xen (where unmap_page_from_agp() is not just a page table attribute change), this also is invalid from a theoretical perspective: One should not assume that gart_to_virt() is still valid after unmapping a page. So minimally (keeping the 2-stage mechanism) a patch like the one below would be needed.

In normal operation, libata should not generate such PIO commands (uses DMA instead), but they could be sent in via SG_IO from userspace. A full workaround might be to break up such commands into sequences of single DRQ ones, but that's just way too complex for something that doesn't normally happen in real life. So, allow the attempt (it often works, despite the errata), but log the event for reference when somebody screams.

My debug showed that there is at least one lguest specific issue (which should be present in 2.6.25 and before aswell) and it got exposed with a kernel oops with the recent fpu dynamic allocation patches. In addition to the previous possible scenario (with fpu_counter), in the presence of lguest, it is possible that the cpu's TS bit it still set and the lguest launcher task's thread_info has TS_USEDFPU still set. This is because of the way the lguest launcher handling the guest's TS bit. (look at lguest_set_ts() in lguest_arch_run_guest()). This can result in a DNA fault while doing unlazy_fpu() in __switch_to(). This will end up causing a DNA fault in the context of new process thats getting context switched in (as opossed to handling DNA fault in the context of lguest launcher/helper process). This is wrong in both pre and post 2.6.25 kernels. In the recent 2.6.26-rc series, this is showing up as NULL pointer dereferences or sleeping function called from atomic context(__switch_to()), as we free and dynamically allocate the FPU context for the newly created threads. Older kernels might show some FPU corruption for processes running inside of lguest. With the appended patch, my test system is running for more than 50 mins now. So atleast some of your oops (hopefully all!) should get fixed. Please give it a try. I will spend more time with this fix tomorrow.

This then just _happened_ to work if you had exactly the right compiler version and exactly the right compiler flags, so that gcc just happened to not create any prologue at all (the gcc-generated epilogue wouldn't matter, since it would never be reached). But the more proper way to fix it is to simply not do this. Move the inline asm to the top level, with no surrounding function at all (the better alternative would be to remove the prologue and make it actually use proper description of the arguments to the inline asm, but that's a bigger change than the one I'm willing to make right now).

Unfortunately, the release function first decrements this variable, and THEN goes on to disable more of the device. This allows for a race where another opener of the device comes in after the decrement of the variable, configures the hardware just to then see the hardware be disabled by the rest of the release function. This patch makes the release function use the same lock as the open function to protect the hardware as well as the variable (which now at least has some locking to protect it).
