From 2bc7509f62da572925ef33365d4fc16f8b4abdd4 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Tue, 15 Jul 2008 17:17:48 +0100 Subject: [ARM] S3C24XX: s3c243xx_clock_register() data can be __initdata Any data being passed to s3c243xx_clock_register() can be marked as __initdata as it is an array of pointers to 'struct clk' that are to be registered on initialisation. The s3c243xx_clock_register function uses this array to register clocks and does not require it to stay around after exit.

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.

What do you think? restore_fpu_checking() calls init_fpu() in error conditions. While this is wrong(as our main intention is to clear the fpu state of the thread), this was benign before commit 92d140e21f1 ("x86: fix taking DNA during 64bit sigreturn"). Post commit 92d140e21f1, live FPU registers may not belong to this process at this error scenario. In the error condition for restore_fpu_checking() (especially during the 64bit signal return), we are doing init_fpu(), which saves the live FPU register state (possibly belonging to some other process context) into the thread struct (through unlazy_fpu() in init_fpu()). This is wrong and can leak the FPU data. For the signal handler restore error condition in restore_i387(), clear the fpu state present in the thread struct(before ultimately sending a SIGSEGV for badframe). For the paranoid error condition check in math_state_restore(), send a SIGSEGV, if we fail to restore the state.

After much debugging with Peter Zijlstra it turned out that the problem is caused by the string of sched_clock() changes - they caused the CPU clock to jump backwards a bit - which confuses the scheduler arithmetics. (which is unsigned for performance reasons) So revert: # c300ba2: sched_clock: and multiplier for TSC to gtod drift # c0c8773: sched_clock: only update deltas with local reads. # af52a90: sched_clock: stop maximum check on NO HZ # f7cce27: sched_clock: widen the max and min time This solves the interactivity problems.

A new ID is choosen when we start to traverse, and we continue through a lock_class only if it's ID hasn't been marked with the new value yet. This short-circuiting is essential especially for high CPU count systems. The scheduler has a runqueue per cpu, and needs to take two runqueue locks at a time, which leads to long chains of backwards and forwards subgraphs from these runqueue lock nodes. Without the short-circuit implemented here, a graph traversal on a runqueue lock can take up to (1 << (N - 1)) checks on a system with N cpus. For anything more than 16 cpus or so, lockdep will eventually bring the machine to a complete standstill. Signed-off-by: David S.

This broke then switch to readonly performed by the shutdown notifier, which needs to work even when the array is still (apparently) active (as md doesn't get told when the filesystem becomes readonly).

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The raid10 resync/recovery code currently limits the amount of in-flight resync IO to 2Meg. This was copied from raid1 where it seems quite adequate. However for raid10, some layouts require a bit of seeking to perform a resync, and allowing a larger buffer size means that the seeking can be significantly reduced. There is probably no real need to limit the amount of in-flight IO at all. Any shortage of memory will naturally reduce the amount of buffer space available down to a set minimum, and any concurrent normal IO will quickly cause resync IO to back off. The only problem would be that normal IO has to wait for all resync IO to finish, so a very large amount of resync IO could cause unpleasant latency when normal IO starts up. So: increase RESYNC_DEPTH to allow 32Meg of buffer (if memory is available) which seems to be a good amount. Also reduce the amount of memory reserved as there is no need to keep 2Meg just for resync if memory is tight. Thanks to Keld for the suggestion.

Instead we now create an extra large mapping which covers all possible lowmem instead of the physical ram that is actually available. This allows the vmi initialization to be done before max_low_pfn could be computed. We also move the vmi_init code very early in the boot process so that nobody accidentally breaks the fixmap dependancy. Signed-off-by: Alok N Kataria Acked-by: Zachary Amsden Signed-off-by: H.

Encapsulation UDP sockets don't need that protection. In fact the locking is deadly for them as they may contain another UDP packet within, possibly with the same addresses. Also the nested bit was copied from TCP. TCP needs it because of accept(2) spawning sockets. This simply doesn't apply to UDP so I've removed it. Signed-off-by: Herbert Xu Signed-off-by: David S.

Since the start of the vmalloc area is not at a fixed address (but the vmalloc end address is, via the per-platform VMALLOC_END define), a default area of 128M is reserved for vmalloc mappings, which can be shrunk or enlarged by passing an appropriate vmalloc= command line option as it is done on x86. On a board with a 3:1 user:kernel split, VMALLOC_END at 0xfe000000, two 512M RAM banks and vmalloc=128M (the default), this patch gives: Truncating RAM at 20000000-3fffffff to -35ffffff (vmalloc region overlap). Memory: 512MB 352MB = 864MB total On a board with a 3:1 user:kernel split, VMALLOC_END at 0xfe800000, two 256M RAM banks and vmalloc=768M, this patch gives: Truncating RAM at 00000000-0fffffff to -0e7fffff (vmalloc region overlap).

Avoid this by moving the DMA translation functions to asm/dma-mapping.h, and converting them to inline functions. Fix the OMAP DMA translation macros to use the correct argument and result types. Also, remove the unnecessary casts in dmabounce.c.

However, take extra care with double_lock_balance() as it can release the already held rq->lock (and therefore change its nesting class). So what can happen is: spin_lock(rq->lock); // this rq subclass 0 double_lock_balance(rq, other_rq); // release rq // acquire other_rq->lock subclass 0 // acquire rq->lock subclass 1 spin_unlock(other_rq->lock); leaving you with rq->lock in subclass 1 So a subsequent double_lock_balance() call can try to nest a subclass 1 lock while already holding a subclass 1 lock. Fix this by introducing double_unlock_balance() which releases the other rq's lock, but also re-sets the subclass for this rq's lock to 0.

Biederman" Date: Sun, 10 Aug 2008 00:35:50 -0700 Subject: x86_64: restore the proper NR_IRQS define so larger systems work. As pointed out and tracked by Yinghai Lu : Dhaval Giani got: kernel BUG at arch/x86/kernel/io_apic_64.c:357! invalid opcode: 0000 [1] SMP CPU 24 ... his system (x3950) has 8 ioapic, irq > 256 This was caused by: commit 9b7dc567d03d74a1fbae84e88949b6a60d922d82 Author: Thomas Gleixner Date: Fri May 2 20:10:09 2008 +0200 x86: unify interrupt vector defines The interrupt vector defines are copied 4 times around with minimal differences. Move them all into asm-x86/irq_vectors.h It appears that Thomas did not notice that x86_64 does something completely different when he merge irq_vectors.h We can solve this for 2.6.27 by simply reintroducing the old heuristic for setting NR_IRQS on x86_64 to a usable value, which trivially removes the regression. Long term it would be nice to harmonize the handling of ioapic interrupts of x86_32 and x86_64 so we don't have this kind of confusion. Dhaval Giani tested an earlier version of this patch by YH which confirms simply increasing NR_IRQS fixes the problem. Signed-off-by: Eric W.

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.

Directly embed an estimator object into every stats object and switch to using the kernel-provided list implementation. This makes the code much simpler and faster, as we do not need to traverse the list of all estimators to find the one belonging to a stats object. There's no need to use an rwlock, as we only have one reader. Also reorder the members of the estimator structure slightly to avoid padding overhead. This can't be done with the stats object as the members are currently copied to our user space object via memcpy() and changing it would break ABI.

Nice debugging work. I'd suggest something like the attached (boot tested) patch as the simple fix for now. I expect the benefits from the less synchronized, multiple-in-flight-data global queue will still outweigh the costs of dynamic allocations. But if worst comes to worst then we just go back to a globally synchronous one-at-a-time implementation, but that would be pretty sad!

This fix also solves the problem with x86-microcode. I've sent alternative patches for microcode, but as this "rely on set_cpus_allowed_ptr() being workable in cpu-hotplug(CPU_ONLINE, ...)" assumption seems to be more broad than what we thought, perhaps this fix should be applied. With this patch we define that by the moment CPU_ONLINE is being sent, a 'cpu' is online and ready for tasks to be migrated onto it.

The one at the top of smp_scan_config() in particular also prints on !CONFIG_SMP/CONFIG_X86_LOCAL_APIC kernels and UP machines without anything resembling MP tables which makes their lowly UP owners wonder... Turn the former Dprintk()s into apic_printk()s instead meaning that their printing is dependent on passing the apic=verbose (or =debug) command line param. On 32-bit, "apic" is a __setup() param which isn't early enough for this code and therefore needs a followup changing it into an early_param(). On 64-bit, it already is.

This patch simply re-plays the current mapping at resume time to restore the table.=20 I noticed this once I started relying on persistent GTT mappings across VT switch in our GEM work -- the old X server and DRM code carefully unbind all memory from the GTT on VT switch, but GEM does not bother. I placed the list management and rewrite code in the generic layer on the assumption that it will be needed on other hardware, but I did not add the rewrite call to anything other than the Intel resume function. Keep a list of current GATT mappings. At resume time, rewrite them into the GATT. This is needed on Intel (at least) as the entire GATT is cleared across suspend/resume.

OK indeed it did have a couple of bugs. Firstly, I wasn't freeing the data properly in the alloc && wait case.

This mapping is not enabled until the architecture specific cpu_init() function is run, which causes problems since some generic code is run before this point. In particular when CONFIG_PRINTK_TIME is enabled, the boot cpu will trap on the access to per-cpu memory at the first printk() call so the boot will fail without the kernel printing anything to the console. Fix this by allocating percpu memory for cpu0 in the kernel data section and doing all initialization to enable percpu access in head.S before calling any generic code.

When a modify_qp() call is cached, the qp state remains untouched until the port is activated, which will leave the qp in the reset state. In the reset state, however, it is not allowed to post SQ WQEs, which confuses applications like ib_mad.

To avoid this problem, the driver needs to detect the second CQE and discard it. For this purpose, introduce an array holding as many elements as the SQ of the QP, called sq_map. Each sq_map entry stores a "reported" flag for one WQE in the SQ. When a work request is posted to the SQ, the respective "reported" flag is set to zero. After the arrival of a CQE, the flag is set to 1, which allows to detect the occurence of a second CQE. The mapping between WQE / CQE and the corresponding sq_map element is implemented by replacing the lowest 16 Bits of the wr_id with the index in the queue map. The original 16 Bits are stored in the sq_map entry and are restored when the CQE is passed to the application.

This is set up in arch_prepare_hugepage(), which is called from alloc_fresh_huge_page_node(). A similar call to arch_prepare_hugepage() is missing for surplus large pages that are allocated in alloc_buddy_huge_page(), which breaks the software emulation mode for (surplus) large pages on s390. This patch adds the missing call to arch_prepare_hugepage(). It will have no effect on other architectures where arch_prepare_hugepage() is a nop. Also, use the correct order in the error path in alloc_fresh_huge_page_node().

A struct file_region is used to track when reservations have been consumed and where. These file_regions are allocated as necessary with kmalloc() which can sleep with the mm->page_table_lock held. This is wrong and triggers may-sleep warning when PREEMPT is enabled. Updates to the underlying file_region are done in two phases. The first phase prepares the region for the change, allocating any necessary memory, without actually making the change. The second phase actually commits the change. This patch makes use of this by checking the reservations before the page_table_lock is taken; triggering any necessary allocations. This may then be safely repeated within the locks without any allocations being required. Credit to Mel Gorman for diagnosing this failure and initial versions of the patch.

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.

This needs to be fixed so that the source files remain usable and good examples of code instead of bad examples. Add the ability to build source files that are in the Documentation/ dir. Add to Kconfig as "BUILD_DOCSRC" config symbol. Use "CONFIG_BUILD_DOCSRC=1 make ..." to build objects from the Documentation/ sources. Or enable BUILD_DOCSRC in the *config system. However, this symbol depends on HEADERS_CHECK since the header files need to be installed (for userspace builds). Built (using cross-tools) for x86-64, i386, alpha, ia64, sparc32, sparc64, powerpc, sh, m68k, & mips.

The problem appears to be that the patched file ends up as part of the target toolchain, but unfortunately the gcc constant folding doesn't appear to eliminate the __invalid_size_argument_for_IOC value early enough. Certainly compiling C++ programs which use _IO... macros as constants fails without this patch.

It will deadlock in xfs_iomap_write_allocate() trying to take the ilock we already hold. This can also show up as complex ABBA deadlocks when multiple threads are triggering memory reclaim when trying to allocate extents. The main cause of this is the fact that delayed allocation is not done in a transaction, so KM_NOFS is not automatically added to the allocations to prevent this recursion. Mark all allocations done for the incore inode extent tree as KM_NOFS to ensure they never recurse back into the filesystem.

Except for the sorting of the inodes this logic is implemented in xfs_lock_inodes, but also partially duplicated in xfs_lock_dir_and_entry in a particularly stupid way adds a lock roundtrip if the inode ordering is not optimal. This patch adds a new helper xfs_lock_two_inodes that takes two inodes and locks them in the most optimal way according to the above locking protocol and uses it for all places that want to lock two inodes. The only caller of xfs_lock_inodes is xfs_rename which might lock up to four inodes.

Setting up the xfs_inode <-> inode link is opencoded in xfs_iget_core now because that's the only place it needs to be done, xfs_initialize_vnode is renamed to xfs_setup_inode and loses all superflous paramaters. The check for I_NEW is removed because it always is true and the di_mode check moves into xfs_iget_core because it's only needed there. xfs_set_inodeops and xfs_revalidate_inode are merged into xfs_setup_inode and the whole things is moved into xfs_iops.c where it belongs.

It mixed exclusive access with completion. That is, we need to mark an object as being flushed before flushing it to disk, and then block any other attempt to flush it until the completion occurs. We do this but adding an extra count to the completion before we start using them. However, we still need to determine if there is a completion in progress, and allow no-blocking attempts fo completions to decrement the count. To do this we introduce: int try_wait_for_completion(struct completion *x) returns a failure status if done == 0, otherwise decrements done to zero and returns a "started" status. This is provided to allow counted completions to begin safely while holding object locks in inverted order. int completion_done(struct completion *x) returns 1 if there is no waiter, 0 if there is a waiter (i.e. a completion in progress). This replaces the use of semaphores for providing this exclusion and completion mechanism.

But it turned out that the latest kernel does not boot because the machine crashes early in the setup code. After some debugging it turned out that the problem is the query_ist() function. If this interrupt with that function is called the machine simply locks up. It looks like a BIOS bug. Looking for a workaround for this problem I wrote the attached patch. It checks for the CPUID instruction and if it is not implemented it does not call the speedstep BIOS function. As far as I know speedstep should be available since some Pentium earliest. Alan Cox observed that it's available since the Pentium II, so cpuid levels 4 and 5 can be excluded altogether. H. Peter Anvin cleaned up the code some more: > Right in concept, but I dislike the implementation (duplication of the > CPU detect code we already have). Could you try this patch and see if > it works for you? which, with a small modification to fix a build error with it the resulting kernel boots on my machine.

Suresh wrote: These padlock instructions though don't use/touch SSE registers, but it behaves similar to other SSE instructions. For example, it might cause DNA faults when cr0.ts is set. While this is a spurious DNA trap, it might cause oops with the recent fpu code changes. This is the code sequence that is probably causing this problem: a) new app is getting exec'd and it is somewhere in between start_thread() and flush_old_exec() in the load_xyz_binary() b) At pont "a", task's fpu state (like TS_USEDFPU, used_math() etc) is cleared. c) Now we get an interrupt/softirq which starts using these encrypt/decrypt routines in the network stack. This generates a math fault (as cr0.ts is '1') which sets TS_USEDFPU and restores the math that is in the task's xstate. d) Return to exec code path, which does start_thread() which does free_thread_xstate() and sets xstate pointer to NULL while the TS_USEDFPU is still set. e) At the next context switch from the new exec'd task to another task, we have a scenarios where TS_USEDFPU is set but xstate pointer is null. This can cause an oops during unlazy_fpu() in __switch_to() Now: 1) This should happen with or with out pre-emption. Viro also encountered similar problem with out CONFIG_PREEMPT. 2) kernel_fpu_begin() and kernel_fpu_end() will fix this problem, because kernel_fpu_begin() will manually do a clts() and won't run in to the situation of setting TS_USEDFPU in step "c" above. 3) This was working before the fpu changes, because its a spurious math fault which doesn't corrupt any fpu/sse registers and the task's math state was always in an allocated state. With out the recent lazy fpu allocation changes, while we don't see oops, there is a possible race still present in older kernels(for example, while kernel is using kernel_fpu_begin() in some optimized clear/copy page and an interrupt/softirq happens which uses these padlock instructions generating DNA fault). This is the failing scenario that existed even before the lazy fpu allocation changes: 0. CPU's TS flag is set 1. kernel using FPU in some optimized copy routine and while doing kernel_fpu_begin() takes an interrupt just before doing clts() 2. Takes an interrupt and ipsec uses padlock instruction. And we take a DNA fault as TS flag is still set. 3. We handle the DNA fault and set TS_USEDFPU and clear cr0.ts 4. We complete the padlock routine 5. Go back to step-1, which resumes clts() in kernel_fpu_begin(), finishes the optimized copy routine and does kernel_fpu_end(). At this point, we have cr0.ts again set to '1' but the task's TS_USEFPU is stilll set and not cleared. 6. Now kernel resumes its user operation. And at the next context switch, kernel sees it has do a FP save as TS_USEDFPU is still set and then will do a unlazy_fpu() in __switch_to(). unlazy_fpu() will take a DNA fault, as cr0.ts is '1' and now, because we are in __switch_to(), math_state_restore() will get confused and will restore the next task's FP state and will save it in prev tasks's FP state. Remember, in __switch_to() we are already on the stack of the next task but take a DNA fault for the prev task. This causes the fpu leakage. Fix the padlock instruction usage by calling them inside the context of new routines irq_ts_save/restore(), which clear/restore cr0.ts manually in the interrupt context. This will not generate spurious DNA in the context of the interrupt which will fix the oops encountered and the possible FPU leakage issue.

First, we're testing the wrong qdisc. We just reset the device queue qdiscs to &noop_qdisc and checking it's state is completely pointless here. We want to wait until the previous qdisc that was sitting at the ->qdisc pointer is not busy any more. And that would be ->qdisc_sleeping. Because of how we propagate the samples qdisc pointer down into qdisc_run and friends via per-cpu ->output_queue and netif_schedule, we have to wait also for the __QDISC_STATE_SCHED bit to clear as well.

v1.2.3 From da5a662a2326931bef25f0e534c9c1702f862399 Mon Sep 17 00:00:00 2001 From: Vladislav Zolotarov Date: Wed, 13 Aug 2008 15:50:00 -0700 Subject: bnx2x: Load/Unload under traffic Load/Unload under traffic Few issues were found when loading and unloading under traffic: - When receiving Tx interrupt call netif_wake_queue if the queue is stopped but the state is open - Check that interrupts are enabled before doing anything else on the msix_fp_int function - In nic_load, enable the interrupts only when needed and ready for it - Function stop_leading returns status since it can fail - Add 1ms delay when unloading the driver to validate that there are no open transactions that already started by the FW - Splitting the "has work" function into Tx and Rx so the same function will be used on unload and interrupts - Do not request for WoL if only resetting the device (save the time that it takes the FW to set the link after reset) - Fixing the device reset after iSCSI boot and before driver load - all internal buffers must be cleared before the driver is loaded Signed-off-by: Vladislav Zolotarov Signed-off-by: Eilon Greenstein Signed-off-by: David S.

When a network namespace is created, other than the init_net and a multicast packet is received, the kernel goes to a hang or a kernel panic. How to reproduce ? * create a child network namespace * create a pair virtual device veth * ip link add type veth * move one side to the pair network device to the child namespace * ip link set netns dev veth1 * ping -I veth0 224.0.0.1 The bug appears because the function ip_mc_init_dev does not initialize the different multicast fields as it exits because it is not the init_net.

Introduced here are trivial no-op versions of the desired accessors for current and other tasks so that other subsystems can start to be converted over more easily. Wrappers are introduced into a new header (linux/cred.h) for UID/GID, EUID/EGID, SUID/SGID, FSUID/FSGID, cap_effective and current's subscribed user_struct. These wrappers are macros because the ordering between header files mitigates against making them inline functions. linux/cred.h is #included from linux/sched.h. Further, XFS is modified such that it no longer defines and uses parameterised versions of current_fs[ug]id(), thus getting rid of the namespace collision otherwise incurred.

This driver was included into the kernel mainly to connect to the ISDN framework. This was done in linux 2.4.x. For 2.6.x, due to the fragile and moving ISDN support, this connection was never realized, and the only use of this driver was for device configuration. In the age of DSL, the demand of ISDN support is getting very low. Meanwhile, with the advent of libusb, an userspace driver was done for the device configuration which works fine for linux and mac. (Thanks to the libusb developers!). The userspace driver is downloadable from the auerswald web site. So this driver is obsolete now and has to be removed. Many thanks to all developers which helped me to bring this driver up and working.

By default all devices that do not have a Linux enabled TRU-Install device (i.e. the device does not have a Linux package on the virtual CD partition) will be switched into "modem mode." Devices that do contain a Linux package in the TRU-Install virtual CD will be allowed to enumerate as a CD-Rom so that either (a) a user can install the packaged software or (b) a user-space application (e.g. udev) can switch it to modem mode. This patch does allow for manual override by adding a usb-storage module parameter 'swi_tru_install' which can force the modem into either mode regardless of what packages it contains.

Most of the RX path work is now done in the RX tasklet, instead of just the final "push to ldisc" step. This addresses some cases of data loss: - A longstanding serial gadget bug: when tty_insert_flip_string() didn't copy the entire buffer, the rest of the characters were dropped! Now that packet stays queued until the rest of its data is pushed to the ldisc. - Another longstanding issue: in the unlikely case that an RX transfer returns data and also reports a fault, that data is no longer discarded. - In the recently added RX throttling logic: it needs to stop pushing data into the TTY layer, instead of just not submitting new USB read requests. When the TTY is throttled long enough, backpressure will eventually make the OUT endpoint NAK. Also: an #ifdef is removed (no longer necessary); and start switching to a better convention for debug messages (prefix them with tty name).

Current driver solves this by a mdelay(1) which is very heavy weighted and slow. This patch applies the workaround from the ISP1760 FAQ by using two different banks for PTD and payload data and using a common wait for them. This wait is done by an additional ISP1760 access (whose timing constraints guarantee the 90ns delay).

Note, this presumes an earlier patch was applied, removing a call to this routine where the lock was held. Slightly improved diagnostics on write URB completion, so we can tell when a write URB gets killed and, if so, how much data it wrote first ... and so that I/O path is normally silent (and can't much change timings).

Those products integrate the Inventra logic + * with other DMA, IRQ, and bus modules, as well as other logic that + * needs to be reflected in this driver. + * + * + * NOTE: the original Mentor code here was pretty much a collection + * of mechanisms that don't seem to have been fully integrated/working + * for *any* Linux kernel version. This version aims at Linux 2.6.now, + * Key open issues include: + * + * - Lack of host-side transaction scheduling, for all transfer types. + * The hardware doesn't do it; instead, software must. + * + * This is not an issue for OTG devices that don't support external + * hubs, but for more "normal" USB hosts it's a user issue that the + * "multipoint" support doesn't scale in the expected ways. That + * includes DaVinci EVM in a common non-OTG mode. + * + * * Control and bulk use dedicated endpoints, and there's as + * yet no mechanism to either (a) reclaim the hardware when + * peripherals are NAKing, which gets complicated with bulk + * endpoints, or (b) use more than a single bulk endpoint in + * each direction. + * + * RESULT: one device may be perceived as blocking another one. + * + * * Interrupt and isochronous will dynamically allocate endpoint + * hardware, but (a) there's no record keeping for bandwidth; + * (b) in the common case that few endpoints are available, there + * is no mechanism to reuse endpoints to talk to multiple devices. + * + * RESULT: At one extreme, bandwidth can be overcommitted in + * some hardware configurations, no faults will be reported. + * At the other extreme, the bandwidth capabilities which do + * exist tend to be severely undercommitted.

Miller" Date: Thu, 14 Aug 2008 01:45:41 -0700 Subject: sparc64: Fix cmdline_memory_size handling bugs. First, lmb_enforce_memory_limit() interprets it's argument (mostly, heh) as a size limit not an address limit. So pass the raw cmdline_memory_size value into it. And we don't need to check it against zero, lmb_enforce_memory_limit() does that for us. Next, free_initmem() needs special handling when the kernel command line trims the available memory. The problem case is if the trimmed out memory is where the kernel image itself resides. When that memory is trimmed out, we don't add those physical ram areas to the sparsemem active ranges, amongst other things.

One in init/main.c and another in arch/x86/smpboot.c. So I nuked the one in arch/x86. Also 64-bit kernels used to handle maxcpus= as documented in Documentation/cpu-hotplug.txt. CPUs with 'id > maxcpus' are initialized but not booted. 32-bit version for some reason ignored them even though all the infrastructure for booting them later is there. In the current mainline both 64 and 32 bit versions are broken. This patch restores the correct behaviour. I've tested x86_64 version on 4- and 8- way Core2 and 2-way Opteron based machines. Various config combinations SMP, !SMP, CPU_HOTPLUG, !CPU_HOTPLUG. Booted with maxcpus=1 and maxcpus=4, etc. Everything is working as expected. So far we've received two reports from different people confirming that 32-bit version also works fine, both on dual core laptops and 16way server machines.

This patch removes __capable() and introduces has_capability() that doesn't set PF_SUPERPRIV on the process being queried. This patch further splits security_ptrace() in two: (1) security_ptrace_may_access(). This passes judgement on whether one process may access another only (PTRACE_MODE_ATTACH for ptrace() and PTRACE_MODE_READ for /proc), and takes a pointer to the child process. current is the parent. (2) security_ptrace_traceme(). This passes judgement on PTRACE_TRACEME only, and takes only a pointer to the parent process. current is the child. In Smack and commoncap, this uses has_capability() to determine whether the parent will be permitted to use PTRACE_ATTACH if normal checks fail. This does not set PF_SUPERPRIV. Two of the instances of __capable() actually only act on current, and so have been changed to calls to capable(). Of the places that were using __capable(): (1) The OOM killer calls __capable() thrice when weighing the killability of a process. All of these now use has_capability(). (2) cap_ptrace() and smack_ptrace() were using __capable() to check to see whether the parent was allowed to trace any process. As mentioned above, these have been split. For PTRACE_ATTACH and /proc, capable() is now used, and for PTRACE_TRACEME, has_capability() is used. (3) cap_safe_nice() only ever saw current, so now uses capable(). (4) smack_setprocattr() rejected accesses to tasks other than current just after calling __capable(), so the order of these two tests have been switched and capable() is used instead. (5) In smack_file_send_sigiotask(), we need to allow privileged processes to receive SIGIO on files they're manipulating. (6) In smack_task_wait(), we let a process wait for a privileged process, whether or not the process doing the waiting is privileged. I've tested this with the LTP SELinux and syscalls testscripts.

At the same time although one process is already waken up by some events, it won't be scheduled immediately. So maybe there exists the following phenomena: a. The current jiffies is already after the predefined jiffies. But before timeout happens, OS has no chance to check the EC status again. b. If preemptible schedule is enabled, maybe preempt schedule will happen before checking loop. When the process is resumed again, maybe timeout already happens, which means that OS has no chance to check the EC status. In such case maybe EC status is already what OS expects when timeout happens. But OS has no chance to check the EC status and regards it as AE_TIME. So it will be more appropriate that OS will try to check the EC status again when timeout happens. If the EC status is what we expect, it won't be regarded as timeout. Only when the EC status is not what we expect, it will be regarded as timeout, which means that EC controller can't give a response in time. http://bugzilla.kernel.org/show_bug.cgi?id=9823 http://bugzilla.kernel.org/show_bug.cgi?id=11141 Signed-off-by: Zhao Yakui Signed-off-by: Zhang Rui Signed-off-by: Andi Kleen --- drivers/acpi/ec.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/acpi/ec.c b/drivers/acpi/ec.c index 76784ae7e6a..13593f9f219 100644 --- a/drivers/acpi/ec.c +++ b/drivers/acpi/ec.c @@ -221,6 +221,8 @@ static int acpi_ec_wait(struct acpi_ec *ec, enum ec_event event, int force_poll) return 0; msleep(1); } + if (acpi_ec_check_status(ec,event)) + return 0; } pr_err(PREFIX "acpi_ec_wait timeout, status = 0x%2.2x, event = %s\n", acpi_ec_read_status(ec), -- cgit v1.2.3 From fa46d3526461e8aa7c0fb39cc1b98ac656695a43 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Fri, 1 Aug 2008 15:58:17 -0600 Subject: ACPI: bounds check IRQ to prevent memory corruption acpi_penalize_isa_irq() should validate irq before using it to index the acpi_irq_penalty[] table.

Current Linux suspend code performs an assignment after the flush, which can add dirty data back to the cache.  On some AMD platforms, additional speculative reads have caused crashes on resume because of this dirty data. Relocate the cache flush to be the very last thing done before halting.  Tie into an assembly line so the compile will not reorder it.  Add some documentation explaining what is going on and why we're doing this.

I can see they're interesting to CPA developers and TLB optimizers, but they don't fit its usual "where has all my memory gone?" usage. If they are to stay, here are some fixes. 1. On x86_32 without PAE, they're not 2M but 4M pages: no need to mess with the internal enum, but show the right name to users. 2. Many machines can never show anything but 0 for DirectMap1G, so suppress that line unless direct_gbpages are really enabled. 3. The unit in /proc/meminfo is kB not number of pages: HugePages messed that up, but they're an example to regret not to follow. 4. Once we use kB, it's easy to see that 1GB has gone missing (which explains why CONFIG_CPA_DEBUG=y soon wraps DirectMap2M negative): because head_64.S's level2_ident_pgt entries were not counted. My fix is not ideal, but works for more and for less than 1G, and avoids interfering with early bootup pagetable contortions.

However, since the manual probing method is brittle and prone to failure on some Abit motherboards (esp. the Abit IP35 Pro) it is better to use DMI to also read the board name and then decide whether or not to probe the bus. At the moment, we do not have a list of valid DMI name strings to use for existing and supported motherboards. This patch only implements DMI probing for the IP35 Pro. For motherboards that can not yet use DMI probing, a warning will be printed to the kernel log asking those users to email me their dmidecode output. The existing manual probing mechanism will be used if CONFIG_DMI is not enabled, if DMI probing fails (for DMI-unsupported motherboards), or if DMI probing fails and the "force" option is set (for DMI-supported motherboards). Ideally in the longer term this manual probing method would be removed. This patch should be safe to apply as it does not change the probing behaviour for most of the supported motherboards, just the IP35 Pro, which already has regressions filed against it in 2.6.26.

The SPI master driver is told to set the device up before adding it to the driver model, so that it's always properly set up when probe() is called. (This is important, because in the case of inverted chipselects, this device can make the bus misbehave until it's properly deselected. It's got to be set up even if no driver binds to the device.) The trouble spot is that it doesn't first verify that no other device has been added using that chipselect. If such a device has been added, its configuration gets trashed. (Fortunately this has not been a common error!) The fix here adds an explicit check, and a mutex to protect the relevant critical region.

Sigh... + The fudge factor MUST match with MAX_DMA_ADDRESS, but + we can't just use that here, because of header file looping... :-( + + Window 1 will be used for all DMA from the ISA bus; yes, that does + limit what memory an ISA floppy or sound card or Ethernet can touch, but + it's also a known limitation on other platforms as well. We use the + same technique that is used on INTEL platforms with similar limitation: + set MAX_DMA_ADDRESS and clear some pages' DMAable flags during mem_init(). + We trust that any ISA bus device drivers will *always* ask for DMAable + memory explicitly via kmalloc()/get_free_pages() flags arguments. + + Note that most PCI bus devices' drivers do *not* explicitly ask for + DMAable memory; they count on being able to DMA to any memory they + get from kmalloc()/get_free_pages(). They will also use window 1 for + any physical memory accesses below 64Mb; the rest will be handled by + window 2, maxing out at 1Gb of memory. I trust this is enough... :-) + + We hope that the area before the first window is large enough so that + there will be no overlap at the top end (64Mb). We *must* locate the + PCI cards' memory just below window 1, so that there's still the + possibility of being able to access it via SPARSE space. This is + important for cards such as the Matrox Millennium, whose Xserver + wants to access memory-mapped registers in byte and short lengths. + + Note that the XL is treated differently from the AVANTI, even though + for most other things they are identical.

Sigh... - - If we try a window at 0 for 1GB as a work-around, we run into conflicts - with ISA/PCI bus memory which can't be relocated, like VGA aperture and - BIOS ROMs. So we must put the windows high enough to avoid these areas. - - We put window 1 at BUS 64Mb for 64Mb, mapping physical 0 to 64Mb-1, - and window 2 at BUS 1Gb for 1Gb, mapping physical 0 to 1Gb-1. - Yes, this does map 0 to 64Mb-1 twice, but only window 1 will actually - be used for that range (via virt_to_bus()). - - Note that we actually fudge the window 1 maximum as 48Mb instead of 64Mb, - to keep virt_to_bus() from returning an address in the first window, for - a data area that goes beyond the 64Mb first DMA window. Sigh... - The fudge factor MUST match with MAX_DMA_ADDRESS, but - we can't just use that here, because of header file looping... :-( - - Window 1 will be used for all DMA from the ISA bus; yes, that does - limit what memory an ISA floppy or sound card or Ethernet can touch, but - it's also a known limitation on other platforms as well. We use the - same technique that is used on INTEL platforms with similar limitation: - set MAX_DMA_ADDRESS and clear some pages' DMAable flags during mem_init(). - We trust that any ISA bus device drivers will *always* ask for DMAable - memory explicitly via kmalloc()/get_free_pages() flags arguments. - - Note that most PCI bus devices' drivers do *not* explicitly ask for - DMAable memory; they count on being able to DMA to any memory they - get from kmalloc()/get_free_pages(). They will also use window 1 for - any physical memory accesses below 64Mb; the rest will be handled by - window 2, maxing out at 1Gb of memory. I trust this is enough... :-) - - We hope that the area before the first window is large enough so that - there will be no overlap at the top end (64Mb). We *must* locate the - PCI cards' memory just below window 1, so that there's still the - possibility of being able to access it via SPARSE space. This is - important for cards such as the Matrox Millennium, whose Xserver - wants to access memory-mapped registers in byte and short lengths. - - Note that the XL is treated differently from the AVANTI, even though - for most other things they are identical. It didn't seem reasonable to - make the AVANTI support pay for the limitations of the XL.

This is often because set_pte_vaddr_pud lacks a __init annotation or the annotation of spp_getpage is wrong. spp_getpage is called from __init (__init_extra_mapping) and non __init (set_pte_vaddr_pud) functions, so it can't be __init.

The use of MAP_32BIT is a legacy hack - to speed up context switching on certain early model 64-bit P4 CPUs. So introduce a new flag to be used by glibc instead, to not constrain 64-bit apps like this. glibc can switch to this new flag straight away - it will be ignored by the kernel.

But, it was indeed getting used during normal menu and ladder governor default case, with no special user setting (Reported by Linus Torvalds).

Current inline asm constraint used in the implementation of prefetch() makes gcc believe that the pointer is dereferenced even though the PLD instruction does not load any data and does not cause a segmentation fault on null pointers, which causes all sorts of interesting results when reaching the end of a linked lists for example. Let's use a better constraint to properly represent the actual usage of the pointer value. Problem reported by Chris Steel.

Fix it by removing the unnecessary '#define __user' from the file. The new headers ivtv.h and ivtvfb.h would have the same problem... if whoever put them there had actually remembered to add them to the Kbuild file while he was at it. Fix those too, and export them as was presumably intended. Note that includes of are also stripped by the header export process, so those don't need to be conditional.

Intel's add/sub documentation specifies they have to be passed as registers. The only operations in the x86-64 architecture which accept arbitrary 64-bit immediates is "movq" to any register; similarly, the only operation which accept arbitrary 64-bit displacement is "movabs" to or from al/ax/eax/rax. http://gcc.gnu.org/onlinedocs/gcc-4.3.0/gcc/Machine-Constraints.html states : e 32-bit signed integer constant, or a symbolic reference known to fit that range (for immediate operands in sign-extending x86-64 instructions).

It also initializes the per_cpu variable and map elements to "_initvalue". The early_* macros provide access to the initial map (usually setup during system init) and the early pointer. This pointer is initialized to point to the early map but is then NULL'ed when the actual per_cpu areas are setup. After that the per_cpu variable is the correct access to the variable.
