At the same time the function ct_atc_pcm_free_substream is stored in the private_free field of the same structure. ct_atc_pcm_free_substream dereferences and ultimately frees the value in the private_data field. But each function can exit in an error case with apcm having been freed, in which case a subsequent call to the private_free function would perform a dereference after free. On the other hand, if the private_free field is not initialized, it is NULL, and not invoked (see snd_pcm_detach_substream in sound/core/pcm.c). To avoid the introduction of a dangling pointer, the initializations of the private_data and private_free fields are moved to the end of the function, past any possible free of apcm.

If it is static, it defaults to __trace_bprintk() otherwise it uses __trace_printk(). A while ago, Lai Jiangshan added __trace_bprintk(). In that patch, we discussed a way to allow modules to use it. The difference between __trace_bprintk() and __trace_printk() is that for faster processing, just the format and args are stored in the trace instead of running it through a sprintf function. In order to do this, the format used by the __trace_bprintk() had to be persistent. See commit 1ba28e02a18cbdbea123836f6c98efb09cbf59ec The problem comes with trace_bprintk() where the module is unloaded. The pointer left in the buffer is still pointing to the format. To solve this issue, the formats in the module were copied into kernel core. If the same format was used, they would use the same copy (to prevent memory leak). This all worked well until we tried to merge everything. At the time this was written, Lai Jiangshan, Frederic Weisbecker, Ingo Molnar and myself were all touching the same code. When this was merged, we lost the part of it that was in module.c. This kept out the copying of the formats and unloading the module could cause bad pointers left in the ring buffer. This patch adds back (with updates required for current kernel) the module code that sets up the necessary pointers.

This triggering happened right after function tracer self test was executed. After doing a config bisect I found that this was caused with having function tracer, paravirt guest, prove locking, and rcu torture all enabled. The rcu torture just enhanced the likelyhood of triggering the bug. Prove locking was needed, since it was the thing that was bugging. Function tracer would trace and disable interrupts in all sorts of funny places. paravirt guest would turn arch_local_irq_* into functions that would be traced. Besides the fact that tracing arch_local_irq_* is just a bad idea, this is what is happening. The bug happened simply in the local_irq_restore() code: if (raw_irqs_disabled_flags(flags)) { \ raw_local_irq_restore(flags); \ trace_hardirqs_off(); \ } else { \ trace_hardirqs_on(); \ raw_local_irq_restore(flags); \ } \ The raw_local_irq_restore() was defined as arch_local_irq_restore(). Now imagine, we are about to enable interrupts. We go into the else case and call trace_hardirqs_on() which tells lockdep that we are enabling interrupts, so it sets the current->hardirqs_enabled = 1. Then we call raw_local_irq_restore() which calls arch_local_irq_restore() which gets traced! Now in the function tracer we disable interrupts with local_irq_save(). This is fine, but flags is stored that we have interrupts disabled. When the function tracer calls local_irq_restore() it does it, but this time with flags set as disabled, so we go into the if () path. This keeps interrupts disabled and calls trace_hardirqs_off() which sets current->hardirqs_enabled = 0. When the tracer is finished and proceeds with the original code, we enable interrupts but leave current->hardirqs_enabled as 0. Which now breaks lockdeps internal processing.

The boot arguments are: earlyprintk=vga ekgdboc=kbd kgdbwait Then simply type "go" at the kdb prompt and boot. The kernel will later emit the message: kgdb: Could not allocate hwbreakpoints And at that point the kernel debugger will cease to work correctly. The solution is to initialize the hw_breakpoint at the same time that all the other perf call backs are initialized instead of using a core_initcall() initialization which happens well after the kernel debugger can make use of hardware breakpoints.

If this happens, we'll end up calling cifs_sb_tlink, taking an extra reference to the tlink and attaching that to the cifsFileInfo. This leads to refcount leaks that manifest as a "stuck" cifsd at umount time. Fix this by only looking up the tlink for the cifsFile on the filp's first pass through this function.

Andiry's xHCI bus suspend patch introduced the possibly of a host controller replaying old commands on the command ring, if the host successfully restores the registers after a resume. After a resume from suspend, the xHCI driver must restore the registers, including the command ring pointer. I had suggested that Andiry set the command ring pointer to the current command ring dequeue pointer, so that the driver wouldn't have to zero the command ring. Unfortunately, setting the command ring pointer to the current dequeue pointer won't work because the register assumes the pointer is 64-byte aligned, and TRBs on the command ring are 16-byte aligned. The lower seven bits will always be masked off, leading to the written pointer being up to 3 TRBs behind the intended pointer. Here's a log excerpt. On init, the xHCI driver places a vendor-specific command on the command ring: [ 215.750958] xhci_hcd 0000:01:00.0: Vendor specific event TRB type = 48 [ 215.750960] xhci_hcd 0000:01:00.0: NEC firmware version 30.25 [ 215.750962] xhci_hcd 0000:01:00.0: Command ring deq = 0x3781e010 (DMA) When we resume, the command ring dequeue pointer to be written should have been 0x3781e010. Instead, it's 0x3781e000: [ 235.557846] xhci_hcd 0000:01:00.0: // Setting command ring address to 0x3781e001 [ 235.557848] xhci_hcd 0000:01:00.0: `MEM_WRITE_DWORD(3'b000, 64'hffffc900100bc038, 64'h3781e001, 4'hf); [ 235.557850] xhci_hcd 0000:01:00.0: `MEM_WRITE_DWORD(3'b000, 32'hffffc900100bc020, 32'h204, 4'hf); [ 235.557866] usb usb9: root hub lost power or was reset (I can't see the results of this bug because the xHCI restore always fails on this box, and the xHCI driver re-allocates everything.) The fix is to zero the command ring and put the software and hardware enqueue and dequeue pointer back to the beginning of the ring. We do this before the system suspends, to be paranoid and prevent the BIOS from starting the host without clearing the command ring pointer, which might cause the host to muck with stale memory. (The pointer isn't required to be in the suspend power well, but it could be.) The command ring pointer is set again after the host resumes.

This caused 1080p24 mode to not work on AP4EVB. Additionally the notifier chain was also called with the wrong mode.

When an async URB is unlinked, the corresponding QH is removed from the async list. If the QH's endpoint is then disabled while the URB is being given back, ehci_endpoint_disable() won't find the QH on the async list, causing it to believe that the QH has been lost. This will lead to a memory leak at best and quite possibly to an oops. The solution is to trust usbcore not to lose track of endpoints. If the QH isn't on the async list then it doesn't need to be taken off the list, but the driver should still wait for the QH to become IDLE before disabling it. In theory this fixes Bugzilla #20182. In fact the race is so rare that it's not possible to tell whether the bug is still present. However, adding delays and making other changes to force the race seems to show that the patch works.

Their current function is to track whether the TX soft-IRQ finished dealing with an skb when the AT-req tasklet takes over, and to discard pending tx datagrams (if there are any) when the local node is removed. The latter does actually contain a race condition bug with TX soft-IRQ and AT-req tasklet. Instead of these lists and the corresponding link in fwnet_packet_task, - a flag in fwnet_packet_task to track whether fwnet_tx is done, - a counter of queued datagrams in fwnet_device do the job as well. The above mentioned theoretic race condition is resolved by letting fwnet_remove sleep until all datagrams were flushed. It may sleep almost arbitrarily long since fwnet_remove is executed in the context of a multithreaded (concurrency managed) workqueue. The type of max_payload is changed to u16 here to avoid waste in struct fwnet_packet_task. This value cannot exceed 4096 per IEEE 1394:2008 table 16-18 (or 32678 per specification of packet headers, if there is ever going to be something else than beta mode).

The netif_stop/wake_queue API is used for this purpose. Without this stop/wake mechanism, datagrams were simply lost whenever the tlabel pool was exhausted. Plus, tlabel exhaustion by firewire-net also prevented other unrelated outbound transactions to be initiated. The chosen queue depth was checked by me to hit the maximum possible throughput with an OS X peer whose receive DMA is good enough to never reject requests due to busy inbound request FIFO. Current Linux peers show a mixed picture of -5%...+15% change in bandwidth; their current bottleneck are RCODE_BUSY situations (fewer or more, depending on TX queue depth) due to too small AR buffer in firewire-ohci. Maxim Levitsky tested this change with similar watermarks with a Linux peer and some pending firewire-ohci improvements that address the RCODE_BUSY problem and confirmed that these TX queue limits are good. Note: This removes some netif_wake_queue from reception code paths. They were apparently copy&paste artefacts from a nonsensical netif_wake_queue use in the older eth1394 driver. This belongs only into the transmit path.

It's basically harmless. Your terminal will be messed up until you type reset. This patch does three things to fix the bug. First, it checks the return value of fb_copy_cmap() in fb_alloc_cmap(). That is enough to fix address the overflow. Second it checks for the integer overflow in fb_set_user_cmap(). Lastly I wanted to cap "cmap->len" in fb_set_user_cmap() much lower because it gets used to determine the size of allocation. Unfortunately no one knows what the limit should be. Instead what this patch does is makes the allocation happen with GFP_KERNEL instead of GFP_ATOMIC and lets the kmalloc() decide what values of cmap->len are reasonable. To do this, the patch introduces a function called fb_alloc_cmap_gfp() which is like fb_alloc_cmap() except that it takes a GFP flag.

Tested on the DM355 EVM. I've been as careful as I can, but it would be good if those with access to other Davinci boards could test. -- The multi-component commit put the initialisation of snd_soc_dai.[capture|playback]_dma_data into snd_soc_dai_ops.hw_params of the McBSP, McASP & VCIF drivers (davinci-i2s.c, davinci-mcasp.c & davinci-vcif.c). The initialisation had to be moved from the probe function in these drivers because davinci_*_dai changed from snd_soc_dai to snd_soc_dai_driver. Unfortunately, the DMA params pointer is needed by davinci_pcm_open (in davinci-pcm.c) before hw_params is called. I have moved the initialisation to a new snd_soc_dai_ops.startup function in each of these drivers. This fix indicates that all platforms that use davinci-pcm must have been broken and need to test with this fix. -- The multi-component commit also changed the McBSP driver name from "davinci-asp" to "davinci-i2s" in davinci-i2s.c without updating the board level references to the driver name. This change is understandable, as there is a similarly named "davinci-mcasp" driver in davinci-mcasp.c. There is probably no 'correct' name for this driver. The DM6446 datasheet calls it the "ASP" and describes it as a "specialised McBSP". The DM355 datasheet calls it the "ASP" and describes it as a "specialised ASP". The DM365 datasheet calls it the "McBSP". Rather than fix this problem by reverting to "davinci-asp", I've elected to avoid future confusion with the "davinci-mcasp" driver by changing it to "davinci-mcbsp", which is also consistent with the names of the functions in the driver. There are other fixes required, so it was never going to be as simple as a revert anyway. -- The DM365 only has one McBSP port (of the McBSP platforms, only the DM355 has 2 ports), so I've changed the the id of the platform_device from 0 to -1. -- In davinci-evm.c, the DM6446 EVM can no longer share a snd_soc_dai_link structure with the DM355 EVM as they use different cpu DAI names (the DM355 has 2 ports and the EVM uses the second port, but the DM6446 only has 1 port). This also means that the 2 boards need different snd_soc_card structures. -- The codec_name entries in davinci-evm.c didn't match the i2c ids in the board files. I have only checked and fixed the details of the names used for the McBSP based platforms. Someone with a McASP based platform (eg DA8xx) should check the others.

GCC's __builtin_prefetch() was introduced a long time ago, all supported GCC versions have it. So this patch is to use it for implementing the prefetch on SH2A and SH4. The current prefetch implementation is almost equivalent with __builtin_prefetch. The third parameter in the __builtin_prefetch is the locality that it's not supported on SH architectures. It has been set to three and it should be verified if it's suitable for SH2A as well. I didn't test on this architecture. The builtin usage should be more efficient that an __asm__ because less barriers, and because the compiler doesn't see the inst as a "black box" allowing better code generation. This has been already done on other architectures (see the commit: 0453fb3c528c5eb3483441a466b24a4cb409eec5). Many thanks to Christian Bruel for his support on evaluate the impact of the gcc built-in on SH4 arch. No regressions found while testing with LMbench on STLinux targets.

There's two different aspects to this: - kernel based perf-events, these should not take out a reference on the creating task and appear on the task's event list since they're not bound to fds nor visible to userspace. - fork() and pthread_create(), these can lead to the creating task dying (and thus the task's event-list becomming useless) but keeping the list and ref alive until the event is closed. Combined they lead to malfunction of the ptrace hw_tracepoints. Cure this by not considering kernel based perf_events for the owner-list and destroying the owner-list when the owner dies.

I suddenly hit the problem during 2.6.37-rc1 regression test, which was introduced by commit '5e98d492406818e6a94c0ba54c61f59d40cefa4a'(Track negative entries v3), following scenario reproduces the issue easily: Node A Node B ================ ============ $touch testfile $ls testfile $rm -rf testfile $touch testfile $ls testfile ls: cannot access testfile: No such file or directory This patch stops tracking the dentry which was negativated by a inode deletion, so as to force the revaliation in next lookup, in case we'll touch the inode again in the same node. It didn't hurt the performance of multiple lookup for none-existed files anyway, while regresses a bit in the first try after a file deletion.

To support such configurations, and to allow smoother transition to runtime PM behavior, MMC_CAP_POWER_OFF_CARD is added, so hosts need to explicitly indicate whether it's OK to power off their cards after boot. SDIO core will enable runtime PM for a card only if that cap is set. As a result, the card will be powered down after boot, and will only be powered up again when a driver is loaded (and then it's up to the driver to decide whether power will be kept or not). This will prevent sdio_bus_probe() failures with setups that do not support powering off the card.

I have seen that the reset-device and configure-endpoint commands, which are invoked from xhci_discover_or_reset_device() and xhci_configure_endpoint(), will sometimes time out. After much debugging, I determined that the commands themselves do not actually time out, but rather their completion events do not get delivered to the right place. This happens when the command ring has just wrapped around, and it's enqueue pointer is left pointing to the link TRB. xhci_discover_or_reset_device() and xhci_configure_endpoint() use the enqueue pointer directly as their command TRB pointer, without checking whether it's pointing to the link TRB. When the completion event arrives, if the command TRB is pointing to the link TRB, the check against the command ring dequeue pointer in handle_cmd_in_cmd_wait_list() fails, so the completion inside the command does not get signaled. The patch below fixes the timeout problem for me. This should be queued for the 2.6.35 and 2.6.36 stable trees.

An xHCI host controller contains USB 2.0 and USB 3.0 ports, which can occur in any order in the PORTSC registers. We cannot read the port speed bits in the PORTSC registers at init time to determine the port speed, since those bits are only valid when a USB device is plugged into the port. Instead, we read the "Supported Protocol Capability" registers in the xHC Extended Capabilities space. Those describe the protocol, port offset in the PORTSC registers, and port count. We use those registers to create two arrays of pointers to the PORTSC registers, one for USB 3.0 ports, and another for USB 2.0 ports. A third array keeps track of the port protocol major revision, and is indexed with the internal xHCI port number. This commit is a bit big, but it should be queued for stable because the "Don't let the USB core disable SuperSpeed ports" patch depends on it. There is no other way to determine which ports are SuperSpeed ports without this patch.

Disabling SuperSpeed ports is a Very Bad Thing (TM). It disables SuperSpeed terminations, which means that devices will never connect at SuperSpeed on that port. For USB 2.0/1.1 ports, disabling the port meant that the USB core could always get a connect status change later. That's not true with USB 3.0 ports. Do not let the USB core disable SuperSpeed ports. We can't rely on the device speed in the port status registers, since that isn't valid until there's a USB device connected to the port. Instead, we use the port speed array that's created from the Extended Capabilities registers.

If \inc != 4 then we will store the data to the wrong offset from \ptr. Luckily, the only caller that passes \rept=2 to this function is __clear_user so we haven't been actively corrupting user data. This patch fixes usracc to pass \inc instead of #4 to usraccoff when it is called a second time.

So in this case the parent being / and the child being foo. Well subvols all have the same inode number, so doing a readdir of / looking for inode 256 will return '.', which obviously doesn't match foo. So instead we need to have our own .get_name so that we can find the right name. Our .get_name will either lookup the inode backref or the root backref, whichever we're looking for, and return the name we find.

Fix PulseAudio "ALSA driver bug" issue (if we have two alternated areas within a 64k DMA buffer, then max period size should obviously be 32k only). Back references: http://pulseaudio.org/wiki/AlsaIssues http://fedoraproject.org/wiki/Features/GlitchFreeAudio . In stop timer function, need to supply ACK in the timer control byte. . Minor log output correction When I did my first PA testing recently, the period size bug resulted in quite precisely observeable half-period-based playback distortion. PA-based operation is quite a bit more underrun-prone (despite its zero-copy optimizations etc.) than raw ALSA with this rather spartan sound hardware implementation on my puny Athlon. Note that even with this patch, azt3328 still doesn't work for both cases yet, PA tsched=0 and tsched (on tsched=0 it will playback tiny fragments of periods, leading to tiny stuttering sounds with some pauses in between, whereas with timer-scheduled operation playback works fine - minus some quite increased underrun trouble on PA vs. ALSA, that is).

If, for some reason, dma channel programming fails, musb code will fallback to PIO mode to transfer that request. In that case, we need to unmap the buffer back to CPU. MUSB RTL1.8 and above cannot handle buffers which are not 32bit aligned. That happens to every request sent by g_ether gadget driver. Since the buffer sent was unaligned, we need to fallback to PIO. Because of that, g_ether was failing due to missing buffer unmapping. With this patch and [1] g_ether works fine with all MUSB revisions. Verified with OMAP3630 board, which has MUSB RTL1.8 using g_ether and g_zero.

Some aspects of PHY initialization are board dependent, things like indicator LED connections and some clocking modes cannot be determined by probing. The dev_flags element of struct phy_device can be used to control these things if an appropriate value can be passed from the Ethernet driver. We run into problems however if the PHY connections are specified by the device tree. There is no way for the Ethernet driver to know what flags it should pass. If we are using the device tree, the struct phy_device will be populated with the device tree node corresponding to the PHY, and we can extract extra configuration information from there. The next question is what should the format of that information be? It is highly device specific, and the device tree representation should not be tied to any arbitrary kernel defined constants. A straight forward representation is just to specify the exact bits that should be set using the "marvell,reg-init" property: phy5: ethernet-phy@5 { reg = <5>; compatible = "marvell,88e1149r"; marvell,reg-init = /* led[0]:1000, led[1]:100, led[2]:10, led[3]:tx */ <3 0x10 0 0x5777>, /* Reg 3,16 <- 0x5777 */ /* mix %:0, led[0123]:drive low off hiZ */ <3 0x11 0 0x00aa>, /* Reg 3,17 <- 0x00aa */ /* default blink periods. */ <3 0x12 0 0x4105>, /* Reg 3,18 <- 0x4105 */ /* led[4]:rx, led[5]:dplx, led[45]:drive low off hiZ */ <3 0x13 0 0x0a60>; /* Reg 3,19 <- 0x0a60 */ }; phy6: ethernet-phy@6 { reg = <6>; compatible = "marvell,88e1118"; marvell,reg-init = /* Fix rx and tx clock transition timing */ <2 0x15 0xffcf 0>, /* Reg 2,21 Clear bits 4, 5 */ /* Adjust LED drive. */ <3 0x11 0 0x442a>, /* Reg 3,17 <- 0442a */ /* irq, blink-activity, blink-link */ <3 0x10 0 0x0242>; /* Reg 3,16 <- 0x0242 */ }; The Marvell PHYs have a page select register at register 22 (0x16), we can specify any register by its page and register number. These are the first and second word. The third word contains a mask to be ANDed with the existing register value, and the fourth word is ORed with the result to yield the new register value. The new marvell_of_reg_init function leaves the page select register unchanged, so a call to it can be dropped into the .config_init functions without unduly affecting the state of the PHY. If CONFIG_OF_MDIO is not set, there is no of_node, or no "marvell,reg-init" property, the PHY initialization is unchanged.

When we allocate a vector for MSI/MSI-X we save away the PIRQ, and the vector value. When we unmap (de-allocate) the MSI/MSI-X vector(s) we need to provide the PIRQ and the vector value. What we did instead was to provide the GSI (which was zero) and the vector value, and we got these unhappy error messages: (XEN) irq.c:1575: dom0: pirq 0 not mapped [ 7.733415] unmap irq failed -22 This patches fixes this and we use the PIRQ value instead of the GSI value.

Instead, we need to unwind, drop the dev->struct_mutex, copy all the relocation entries to a vmalloc array (to avoid any potential circular deadlocks when resolving the pagefault), retake the mutex and then apply the relocations. Afterwards, we need to again drop the lock and copy the vmalloc array back to userspace. v2: Incorporate feedback from Daniel Vetter.
