At present, if a signal is being delivered, and the process has specified delivery of that signal on an alternate stack but the alternate stack that has been specified is invalid (i.e. the kernel gets a fault writing to the alternate stack), then we (correctly) give the process a SIGSEGV but we put the wrong signal mask in the saved state on the stack - i.e. we put the mask that would have been established for the original signal handler there. This patch fixes it by making setup_rt_frame, handle_rt_signal32 and handle_signal32 return a status code to indicate whether they successfully established a stack frame. If they fail, the caller doesn't block the signals specified for the signal handler.

The problem that this patch fixes is that a process being single-stepped will execute one instruction too many in certain cases: when a signal is delivered, when a signal handler returns, and when a system call instruction is single-stepped. This patch fixes it by checking if the process is being single-stepped in the syscall exit path and on signal delivery, and stopping it if so. To avoid slowing down the syscall exit path in the normal case, we use a bit in the thread_info flags, which can be tested along with the other bits we already test in the syscall exit path.

(This is David's patch plus a couple of comment fixes from me.) Without this patch, a signal handler that is called as a result of delivery of a signal while a process is waiting in sigsuspend() will have wrong values given to it for the second and third arguments. The reason is that we were returning to userspace via the syscall return path, which doesn't bother to restore r4 and r5. This patch arranges for the return to userspace to be done via ret_from_except in this case, which restores all registers.

This patch fixes both that failure mode and some others possible. What Klaus saw was a false negative (i.e. ECHILD when there was a child) when the group leader was a zombie but delayed because other children live; in the test program this happens in a race between the two threads dying on a signal. The change to the TASK_TRACED case avoids a potential false positive (blocking, or WNOHANG returning 0, when there are really no children left), in the race condition where my_ptrace_child returns zero.

This makes the RWC bit serve double duty, but that appears to work OK, and the only penalty is increased power consumption (from OHCI clocks) on boards/chips that don't work right.

The previous version of the meye driver used dma_addr_t types to build those addresses and ensured that sizeof(dma_addr_t) = 4 by disabling HIGHMEM64G in Kconfig. However, this way of doing it also makes meye unavailable on some kernel configurations. As Arjan said previously, future Fedora kernels may have HIGHMEM64G activated by default (davej says it won't happen, at least for now...). Other distributions may do the same and this will require meye users to recompile the whole kernel. The attached patch makes the meye driver use dma_addr_t addresses internally, but converts them to u32 before giving them to the hardware.

This was cleared by pmac so far, but a bug in the definition of the variable make that ineffective until 2.6.10, and so we never called pci_assign_unassigned_resources(). With 2.6.10, that bug was fixed and so we now call it, which results in some problems. Some devices who have perfectly valid assigned addresses by firmware end up beeing moved around anyway, which is a BAD thing can can break boot on some machines since it breaks the relationship between addresses in Open Firmware device-tree and actual location of PCI devices. (Some low level things like the PIC are ioremap'ed based on their OF address, way before the PCI based ASIC hosting them has been found). This also break the "offb" default framebuffer driver since the video card ends up beeing moved around as well. For now, the fix is to set pci_probe_only on pmac, thus reverting to the old behaviour. In the long run, it would be interesting to "fix" pci_assign_unassigned_resources() so that it does what it's name claims, and only assigns things that have been left unassigned instead of moving things around gratuituously...

If READ_IMPLIES_EXEC then the break area is VM_EXEC, but omitted from exec_vm since do_brk contains no __vm_stat_account call. Later munmaps count its pages out of exec_vm, hence (exec_vm - VmExe) can go negative. do_brk is right not to call __vm_stat_account, its pages shouldn't need to be counted. What's wrong is that __vm_stat_account is counting all the VM_EXEC pages, whereas (to mimic 2.4 and earlier 2.6) it should be leaving VM_WRITE areas and non-vm_file areas out of exec_vm. VmLib may still appear larger than before - where a READ_IMPLIES_EXEC personality makes what was a readonly mapping of a file now executable e.g. /usr/lib/locale stuff. And a program which mprotects its own text as writable will appear with wrapped VmLib: sorry, but while it's worth showing ordinary programs as ordinary, it's not worth much effort to avoid showing odd ones as odd.

It failed because the CPU we happened to be running on was CPU 2, but hard_smp_processor_id() is defined to 0 for !CONFIG_SMP. (Note that this code runs quite early, as part of init_IRQ, so hard_smp_processor_id() should be the physical ID of the boot cpu.) This patch does a minimal fix to make it work. I think this patch should go in 2.6.10.

On iSeries and on POWER5 machines, there is a data structure which is used for communication between the hypervisor and the kernel, called the `lppaca'. The kernel tells the hypervisor where it is, and the hypervisor requires that it doesn't cross a page boundary. With other changes in the last few months we have ended up with a situation where it could cross a page boundary. This patch increases the alignment requirement for the struct to make sure that it can't cross a page boundary. This is a bug fix and should go into 2.6.10.

Key features of this new driver: - Small, relatively tight code; - Uses the 2.6 platform_device and usbcore HCD infrastructures; - Compiles (x86, ARM) and works (ARM/PXA255); - Passed a day's worth of "usbtest" stress testing (on 2.6.9). I've enumerated over a dozen different devices with it, and actually tested mice, hubs, keyboards, and usb-storage. There's a hardware erratum that prevents this chip from working with certain external hubs. There's scope yet for some performance work here; and some IRQ quirks linger. This PIO-only driver should serve as a model for some other non-DMA USB host controllers (like isp1161, isp1362, td243) used in embedded Linuxes ... in particular, showing how to maintain async and periodic schedules without pointless emulation of OHCI DMA queues and/or registers. The driver should handle ISO, but since it doesn't implement the special urb->iso_frame_desc[] "pseudo-queue" model (and since Linux can't guarantee low enough IRQ latencies!), ISO is disabled.

The fix: - Unlinks the QH before updating it; only the tail can safely be updated "live", not the queue head. The async schedule (all control/bulk QHs) and periodic schedule (interrupt QH) work a bit differently ... high bandwidth transfers will hiccup. - Moves "update QH" and "clear toggle" logic into one new qh_refresh() routine, used in several places. The race shows readily enough under load with the right hardware. The controller silicon might be relatively slow, or maybe it's the bus that's slow/busy: Host Controller --- ---------- reads two TD pointers update two TD pointers wmb() activate QH reads rest of QH Net result is that the HC treated old TD pointers as valid, and things started misbehaving. Busy controllers would misbehave worse; some systems wouldn't notice more than a slowdown, especially with light USB loads. This affects behavior in two cases. The uncommon one is when an endpoint gets an error and halts. The more common one happens when the controller runs off the end of its queue and overlays an inactive "dummy" TD into the QH ... something the spec says shouldn't happen, but which more silicon seems to be doing. (Presumably to reduce DMA chatter.)

We were using 0x08000000 instead of TASK_UNMAPPED_BASE so that running something like "/lib/ld-linux.so.2 emacs" would work. The issue there was that wherever /lib/ld-linux.so.2 gets mapped (controlled by ELF_ET_DYN_BASE), that is where the BSS start for the process ends up. Now, emacs allocates dynamic memory for LISP objects from the BSS, and needs the top 4 bits of the virtual address to be clear so that it can encode LISP type and GC marking information there. But making this obscure emacs case work breaks lots of other stuff. For example, programs with a reasonably large data section fail to load via direct ld.so interpreter execution because the data section is large enough to begin overlapping with the ELF_ET_DYN_BASE area. The /lib/ld-linux.so.2 emacs case does not work on a lot of platforms due to this issue, including i386, so it is not worth making work on sparc either. It is indeed useful sometimes when debugging a new experimental build of glibc for example, but people doing that can hack the value of ELF_ET_DYN_BASE in their kernels. Perhaps at some point we will make a sysctl controllable value. Signed-off-by: David S.

The reasons for revamping the DVB frontend architecture: Just as analog TV cards, DVB cards need some sort of tuner to tune to the desired frequency of the digital transponder. Tuning alone doesn't give you a digital DVB datastream, however, you need a demodulator as well. The combination of tuner and demodulator is called frontend in the DVB world. Tuner and demodulator are both accessed via the serial i2c bus on all DVB cards out there. So, technically a frontend consists of two i2c helper chipsets. In former times when there was only a handful of different DVB cards, the frontend was encapsulated in one tin box. Some people had the idea that there should be one "frontend driver" instead of dedicated tuner and demodulator drivers. A bad idea. As time went on, different manufacturers used the same tuner and demodulator combination, but used a different wiring for the tuner or did other technical changes. The only possibility to support different cards with one combined frontend driver was to add hardware dependent tuner code inside the generic i2c frontend drivers. Yuck. So there was a need for communication between the i2c frontend driver and the hardware depenedent driver, for example to exchange initialization code for the tuner. Unfortunately, the i2c infrastructure is one way, from the i2c client to the i2c adapter using a non-typesafe ioctl() like interface, which is ugly by itself. Greg K-H and others refused the idea to add an iotctl() like interface from the i2c adapter to the i2c client and instead proposed to use a typesafe interface instead. We all agreed with that. The existing i2c infrastructure heavily depends on the probing facility, ie. clients probe for their existence on i2c busses. This is dumb for most i2c busses out there that sit on dedicated hardware. A DVB card is uniquely identified with pci or usb subvendor and subsystem ids, so on that particular bus we exactly *know* which kinds of i2c helper chipsets sit on there. Up to now this wasn't a problem, because we could fix all conflicts manually until half a year ago. By that date, we found two different DVB designs which used different demodulators that unfortunately use the same i2c address and which cannot be distinguished by hardware tricks (ie. different number of registers, some fixed hw dependent register,...) Getting a usable DVB card depended on the load order of the modules, because the i2c core probed the demodulator drivers one after another and the first one won the race. Compiling all drivers statically into the kernel resulted in non-working cards. Our solution is as follows: we agreed to keep the basic underlying kernel i2c infrastructure, but we decided not to register our bussed and chipsets to the kernel i2c "probing" infrastructure. Instead, we killed the tuner parts of the frontend drivers and put them into the dedicated hardware drivers (this is were they technically belong, they are highly hardware dependent) and we changed the frontend drivers to pure demodulator drivers (which are hardware independend). There is now a type-safe functional dependency between the drivers and the demodulator drivers, the drivers explicitely ask the demodulator drivers to attach to their i2c bus. The only negative aspect of that approach is that for some hardware there are now more dependencies to demodulator drivers than needed, ie. a small amount of memory is wasted.

This is incorrect, and fails on e.g. platforms that copy DMA memory back and forth (swiotlb on Intel EM64T and IA64). Remove this assumption by ensuring that we only call the DMA mapping routines if we really are going to use DMA for data xfer. Also: remove a bogus WARN_ON() in ata_sg_init_one() which caused bug reports (but no problems).

The problem was that the if you have a USB keyboard and it is set to the input device for the firmware, it will still be active when the kernel is started. That means that the OHCI controller has pointers to various memory areas that it polls for transfers to do. When we start using that same memory in the kernel, bad things can happen. (This isn't a problem on powermacs because the Apple OF implements a "quiesce" call which turns off all the devices it is using.) This patch fixes the problem by calling the Open Firmware "close" method for the input device. Stephen Rothwell and I have verified that doing this fixes the problem on the POWER5 machine where we observed it. I verified that this patch doesn't cause any problems on powermacs. I think this patch should go into 2.6.10 since it fixes a nasty memory corruption bug that can cause rather subtle and hard-to-diagnose problems during boot. (The symptom on the POWER5 machine with the particular kernel that we were using was that reading /proc/net/tcp would oops, due to one of the pointers in tcp_ehash being corrupted.)
