The file has the following example code: struct scatterlist sg[2]; [...] if (crypto_hash_digest(&desc, &sg, 2, result)) which does not match the declaration of crypto_hash_digest() in include/linux/crypto.h. (static inline int crypto_hash_digest(struct hash_desc *desc, struct scatterlist *sg, unsigned int nbytes, u8 *out) The code in the example passes the address of a pointer (an array actually) as the second argument, while the function expects the pointer itself. I have attached a patch to fix this. Signed-off-by: Herbert Xu commit f70ee5ec8fc59ba2d905e6daf0d395edf6fb461d Author: J. Bruce Fields Date: Wed Mar 21 08:50:12 2007 +1100 [CRYPTO] api: scatterwalk_copychunks() fails to advance through scatterlist In the loop in scatterwalk_copychunks(), if walk->offset is zero, then scatterwalk_pagedone rounds that up to the nearest page boundary: walk->offset += PAGE_SIZE - 1; walk->offset &= PAGE_MASK; which is a no-op in this case, so we don't advance to the next element of the scatterlist array: if (walk->offset >= walk->sg->offset + walk->sg->length) scatterwalk_start(walk, sg_next(walk->sg)); and we end up copying the same data twice. It appears that other callers of scatterwalk_{page}done first advance walk->offset, so I believe that's the correct thing to do here. This caused a bug in NFS when run with krb5p security, which would cause some writes to fail with permissions errors--for example, writes of less than 8 bytes (the des blocksize) at the start of a file.

There are tons of bad pte print (pfn < max_low_pfn) reports when the crash kernel boots up, all those reported bad pages are inside initmem range; That is because if the crash kernel code and data happens to be at the beginning of the 1st node. build_node_maps in discontig.c will bypass reserved regions with filter_rsvd_memory. Since min_low_pfn is calculated in build_node_map, so in this case, min_low_pfn will be greater than kernel code and data. Because pages inside initmem are freed and reused later, we saw pfn_valid check fail on those pages. I think this theoretically happen on a normal kernel. When I check min_low_pfn and max_low_pfn calculation in contig.c and discontig.c. I found more issues than this. 1. min_low_pfn and max_low_pfn calculation is inconsistent between contig.c and discontig.c, min_low_pfn is calculated as the first page number of boot memmap in contig.c (Why? Though this may work at the most of the time, I don't think it is the right logic). It is calculated as the lowest physical memory page number bypass reserved regions in discontig.c. max_low_pfn is calculated include reserved regions in contig.c. It is calculated exclude reserved regions in discontig.c. 2. If kernel code and data region is happen to be at the begin or the end of physical memory, when min_low_pfn and max_low_pfn calculation is bypassed kernel code and data, pages in initmem will report bad. 3. initrd is also in reserved regions, if it is at the begin or at the end of physical memory, kernel will refuse to reuse the memory. Because the virt_addr_valid check in free_initrd_mem. So it is better to fix and clean up those issues. Calculate min_low_pfn and max_low_pfn in a consistent way.

When converting tty_io.c to store pids as struct pid pointers instead of pid_t values it appears I overlooked two places where we stop using the pid value. The very obvious one is in do_tty_hangup, and the one the less obvious one in __proc_set_tty. When looking into the code __proc_set_tty only has pids that need to be put because of failures of other parts of the code to properly perform hangup processing. Fixing the leak here in __proc_set_tty is easy and obviously correct so I am doing that first. Fixing the places that should be performing hangup processing is much less obviously correct. So those I'm aiming those patches at -mm. for now, so the can age a while before they are merged. Signed-off-by: Eric W.

The resulting error is quite small on a bunch of evaluated platforms and is less harming than the observed false positives. We need to keep the verification on systems, which have no PM-Timer to avoid bogus local APIC timer calibrations in the range of factor 2-10, which can be observed when swicthing off the PM-timer support in the kernel configuration. The wrong calibration values are probably caused by SMM code trying to emulate a PS/2 keyboard from a (maybe connected or not) USB keyboard. This prohibits the accurate delivery of PIT interrupts, which are used to calibrate the local APIC timer. Unfortunately we have no way to disable this BIOS misfeature in the early boot process. Add also the dropped cpu_relax() back to the wait loops.

This means that a guest pde (mapping 4MB of memory) is mapped to two shadow pdes (mapping 2MB each). When the guest writes to a pte or pde, we intercept the write and emulate it. We also remove any shadowed mappings corresponding to the write. Since the mmu did not account for the doubling in the number of pdes, it removed the wrong entry, resulting in a mismatch between shadow page tables and guest page tables, followed shortly by guest memory corruption. This patch fixes the problem by detecting the special case of writing to a non-pae pde and adjusting the address and number of shadow pdes zapped accordingly.

(additionally "n" cases have been obsoleted for few years). Therefore use DMA by default and remove CONFIG_IDEDMA_{ICS,PCI}_AUTO (also remove no longer needed CONFIG_IDEDMA_AUTO). This fixes DMA support for rare configurations where CONFIG_IDEDMA_{ICS,PCI}_AUTO was set to "n" but "hdparm -d 1" was used to enable DMA support and which were forced to PIO mode by "ide: don't allow DMA to be enabled if CONFIG_IDEDMA_{ICS,PCI}_AUTO=n" patch. There is no functionality loss because "ide=nodma" kernel option is still available.

However the code responsible for manually enabling DMA ("hdparm -d 1") has a bug which results in DMA being erroneously enabled - ide_set_dma() incorrectly passes "0" return value to set_using_dma(). This may work if BIOS/firmware configured the host/device for DMA and chipset allows independent configuration of DMA/PIO modes but won't work after suspend and is generally unsafe on many chipsets (possibly including data corruption if the same registers are used for DMA/PIO timings). This patch fixes kernel bugzilla bug #8169 (piix host driver fixes for setting PIO mode exposed the problem described above). The side-effect of the fix is that some rare configuration may be forced to PIO mode when DMA mode was previously used - this is addressed by the next patch which removes CONFIG_IDEDMA_{PCI,ICS}_AUTO config option completely. Thanks goes out to Patrick Horn for reporting the issue, narrowing it down to the specific commit and testing the fix. Also thanks to Sergei Shtylyov for help in debugging the problem.

Sigh, I never figured out from the code and the bug reports what's going on. The observed hangs are caused by a stale state transition of the clock event devices, which keeps the RCU synchronization away from completion, when the non boot CPU is brought back up. The suspend/resume in oneshot mode needs the similar care as the periodic mode during suspend to RAM. My assumption that the state transitions during the different shutdown/bringups of s2disk would go through the periodic boot phase and then switch over to highres resp. nohz mode were simply wrong. Add the appropriate suspend / resume handling for the non periodic modes.

The problem is that in fs/binfmt_elf.c:randomize_stack_top() randomizes the stack to within 0x7ff pages. On 4k page machines, this is 8MB; on 64k page boxes, this is 128MB. The problem is that the new binary layout (selected in arch_pick_mmap_layout) places the mapping segment 128MB or the stack rlimit away from the top of the process memory, whichever is larger. If you chose an rlimit of less than 128MB (most defaults are in the 8Mb range) then you can end up having your entire stack randomized away. The fix is to make randomize_stack_top() only steal at most 8MB, which this patch does. However, I have to point out that even with this, your stack rlimit might not be exactly what you get if it's > 128MB, because you're still losing the random offset of up to 8MB. The true fix should be to leave an explicit gap for the randomization plus a buffer when determining mmap_base, but that would involve fixing all the architectures.

This patch corrects that oversight, fixing - documentation - platforms supporting the GPIO interface - users of that call (just one for now, others are pending) There's only one user of this call for now since most platforms are still using non-generic GPIO setup code, which in most cases already couples the initial value with its "set output mode" request. Note that most platforms are clear about the hardware letting the output value be set before the pin direction is changed, but the s3c241x docs are vague on that topic ... so those chips might not avoid the glitches.

The workqueue associated with the bus was destroyed before the call to spi_unregister_master. That meant that spi devices on that bus would be unable to do IO in their remove method. The shutdown flag should have been able to prevent a segfault, but was never getting set. By waiting to destroy the workqueue until after the master is unregistered, devices are able to do IO in their remove methods. An added benefit is that neither the shutdown flag nor a wait for the queue of messages to empty is needed.

If this fails the interface tries to tell the caller that the cache is inconsistent by returning EIO. Before this patch we had the problem where this invalidation failure would clobber -EIOCBQUEUED as it made its way from fs/direct-io.c to fs/aio.c. Both fs/aio.c and bio completion call aio_complete() and we reference freed memory, usually oopsing. This patch addresses this problem by invalidating before the write so that we can cleanly return -EIO before ->direct_IO() has had a chance to return -EIOCBQUEUED. There is a compromise here. During the dio write we can fault in mmap()ed pages which intersect the written range with get_user_pages() if the user provided them for the source buffer. This is a crazy thing to do, but we can make it mostly work in most cases by trying the invalidation again. The compromise is that we won't return an error if this second invalidation fails if it's an AIO write and we have -EIOCBQUEUED. This was tested by having two processes race performing large O_DIRECT and buffered ordered writes. Within minutes ext3 would see a race between ext3_releasepage() and jbd holding a reference on ordered data buffers and would cause invalidation to fail, panicing the box. The test can be found in the 'aio_dio_bugs' test group in test.kernel.org/autotest. After this patch the test passes.

We have to make sure to use base-pagesize TLB entries even during the early transition period where we need TLB miss handling but don't have the kernel page tables setup yet for the linear region. Also, it is necessary therefore to not use the 4MB TSB for these translations, and instead use the normal kernel TSB. This allows us to also get rid of the 4MB tsb for debug builds which shrinks the kernel a little bit. Signed-off-by: David S.

The ipv6_fl_socklist from listening socket is inadvertently shared with new socket created for connection. This leads to a variety of interesting, but fatal, bugs. For example, removing one of the sockets may lead to the other socket's encountering a page fault when the now freed list is referenced. The fix is to not share the flow label list with the new socket. Signed-off-by: Masayuki Nakagawa Signed-off-by: David S.

The sh-sci sci_br_interrupt() handler was failing to call in to uart_handle_break(), which was something that only the SH-3 path was doing, fix that up. Additionally, SUPPORT_SYSRQ seems to have moved down too far, move it back to the top so uart_handle_break() and friends aren't no-ops.

SH-3 and SH-4 were trampling the register, and SH-2 wasn't even setting it in the first place. This ended up with some rather broken behaviour in the sysrq show_regs().

This left everyone else without hotplug CPU control. Fix ARM for this brain damage.

The code for performing the calculation was only in the SH-4 probe path, move it out to the common path so the other parts get this right too.

This fixes up some compile failures for cases where we don't include all of the headers. There's not much point in keeping the struct references around anyways, most of the others have been converted already.

For some reason sh was missing __NR_readahead, even though the syscall was wired up, and the slot was reserved. Caught with dwmw2's missing syscall checker.

When a SH7751R system includes a card that has wide range space like a graphics card, the pci-pci bridge controller can't set the correct address range. For example, when *lower_limit is 0xfd000000 and bar_size is 0x4000000, in the following code at arch/sh/drivers/pci/pci-auto.c, 0x0 is set in bar_value. pciauto_setup_bars() { ... bar_value = ((*lower_limit - 1) & ~(bar_size - 1)) + bar_size; ... *lower_limit = bar_value + bar_size; } As a result, 0x4000000 is set in *lower_limit, but this value is wrong. The following patch avoids this problem by checking the range of the value and refusing to update the BAR if the calculated value ends up being bogus.
