This has security implications because this can be triggered by simply sending a specially crafted ethernet frame to a target victim, effectively crashing that host. Thus this qualifies, I think, as a remote DoS. Here is the frame I used to trigger the crash, in npg format: { # Ethernet header ----- XX XX XX XX XX XX # Destination MAC 00 00 00 00 00 00 # Source MAC 00 1D # Length # LLC header ----- AA AA 03 08 00 07 80 9B # Appletalk # Appletalk header ----- 00 1B # Packet length (invalid) 00 01 # Fake checksum 00 00 00 00 # Destination and source networks 00 00 00 00 # Destination and source nodes and ports # Payload ----- 0C 0D 0E 0F 10 11 12 13 14 } The destination MAC address must be set to those of the victim. The severity is mitigated by two requirements: * The target host must have the appletalk kernel module loaded. I suspect this isn't so frequent. * AppleTalk frames are non-IP, thus I guess they can only travel on local networks. I am no network expert though, maybe it is possible to somehow encapsulate AppleTalk packets over IP. The bug has been reported back in June 2004: http://bugzilla.kernel.org/show_bug.cgi?id=2979 But it wasn't investigated, and was closed in July 2006 as both reporters had vanished meanwhile. This code was new in kernel 2.6.0-test5: http://git.kernel.org/?p=linux/kernel/git/tglx/history.git;a=commitdiff;h=7ab442d7e0a76402c12553ee256f756097cae2d2 And not modified since then, so we can assume that vanilla kernels 2.6.0-test5 and later, and distribution kernels based thereon, are affected. Note that I still do not know for sure what triggered the bug in the real-world cases. The frame could have been corrupted by the kernel if we have a bug hiding somewhere. But more likely, we are receiving the faulty frame from the network. Signed-off-by: Jean Delvare Signed-off-by: David S.

Digging in it looks to be a result of the mix of the clocksource list changes and my clocksource initialization changes. With the -rt tree, using a bad TSC, even for a short period of time can results in a hang at boot. I was not able to reproduce this hang w/ mainline, but I'm not completely certain that someone won't trip on it. This patch resolves the issue by initializing the jiffies clocksource earlier so a bad TSC won't get selected just because nothing else is yet registered.

Biederman Date: Tue Apr 3 00:07:30 2007 -0600 [PATCH] net: Ignore sysfs network device rename bugs. The generic networking code ensures that no two networking devices have the same name, so there is no time except when sysfs has implementation bugs that device_rename when called from dev_change_name will fail. The current error handling for errors from device_rename in dev_change_name is wrong and results in an unusable and unrecoverable network device if device_rename is happens to return an error. This patch removes the buggy error handling. Which confines the mess when device_rename hits a problem to sysfs, instead of propagating it the rest of the network stack. Making linux a little more robust. Without this patch you can observe what happens when sysfs has a bug when CONFIG_SYSFS_DEPRECATED is not set and you attempt to rename a real network device to a name like (broken_parity_status, device, modalias, power, resource2, subsystem_vendor, class, driver, irq, msi_bus, resource, subsystem, uevent, config, enable, local_cpus, numa_node, resource0, subsystem_device, vendor) Greg has a patch that fixes the sysfs bugs but he doesn't trust it for a 2.6.21 timeframe.

The git commit c2fda5fed81eea077363b285b66eafce20dfd45a which added the page_test_and_clear_dirty call to page_mkclean and the git commit 7658cc289288b8ae7dd2c2224549a048431222b3 which fixes the "nasty and subtle race in shared mmap'ed page writeback" problem in clear_page_dirty_for_io cause data corruption on s390. The effect of the two changes is that for every call to clear_page_dirty_for_io a page_test_and_clear_dirty is done. If the per page dirty bit is set set_page_dirty is called. Strangly clear_page_dirty_for_io is called for not-uptodate pages, e.g. over this call-chain: [<000000000007c0f2>] clear_page_dirty_for_io+0x12a/0x130 [<000000000007c494>] generic_writepages+0x258/0x3e0 [<000000000007c692>] do_writepages+0x76/0x7c [<00000000000c7a26>] __writeback_single_inode+0xba/0x3e4 [<00000000000c831a>] sync_sb_inodes+0x23e/0x398 [<00000000000c8802>] writeback_inodes+0x12e/0x140 [<000000000007b9ee>] wb_kupdate+0xd2/0x178 [<000000000007cca2>] pdflush+0x162/0x23c The bad news now is that page_test_and_clear_dirty might claim that a not-uptodate page is dirty since SetPageUptodate which resets the per page dirty bit has not yet been called. The page writeback that follows clobbers the data on disk. The simplest solution to this problem is to move the call to page_test_and_clear_dirty under the "if (page_mapped(page))". If a file backed page is mapped it is uptodate.

So for lba48 commands, tf_read() won't be reading back the full lba48 register contents.. Correct?

Biederman Date: Tue Apr 3 01:41:49 2007 -0600 [PATCH] msi: synchronously mask and unmask msi-x irqs. This is a simplified and actually more comprehensive form of a bug fix from Mitch Williams . When we mask or unmask a msi-x irqs the writes may be posted because we are writing to memory mapped region. This means the mask and unmask don't happen immediately but at some unspecified time in the future. Which is out of sync with how the mask/unmask logic work for ioapic irqs. The practical result is that we get very subtle and hard to track down irq migration bugs. This patch performs a read flush after writes to the MSI-X table for mask and unmask operations. Since the SMP affinity is set while the interrupt is masked, and since it's unmasked immediately after, no additional flushes are required in the various affinity setting routines. The testing by Mitch Williams on his especially problematic system should still be valid as I have only simplified the code, not changed the functionality. We currently have 7 drivers: cciss, mthca, cxgb3, forceth, s2io, pcie/portdrv_core, and qla2xxx in 2.6.21 that are affected by this problem when the hardware they driver is plugged into the right slot. Given the difficulty of reproducing this bug and tracing it down to anything that even remotely resembles a cause, even if people are being affected we aren't likely to see many meaningful bug reports, and the people who see this bug aren't likely to be able to reproduce this bug in a timely fashion. So it is best to get this problem fixed as soon as we can so people don't have problems. Then if people do have a kernel message stating "No irq for vector" we will know it is yet another novel cause that needs a complete new investigation.

Basically the stack frame of scsi_send_eh_cmd() is what ends up in the sense buffer. Depending upon how pointers look on a given platform, you can end up getting sr_ioctl.c errors when you mount a cdrom. If the CDROM gives a check condition for GPCMD_GET_CONFIGURATION issued by drivers/cdrom/cdrom.c:cdrom_mmc_profile(), sr_ioctl will spit out this error message in sr_do_ioctl() with the way pointers are on sparc64: default: printk(KERN_ERR "%s: CDROM (ioctl) error, command: ", cd->cdi.name); __scsi_print_command(cgc->cmd); scsi_print_sense_hdr("sr", &sshdr); err = -EIO; This is the error Tom Callaway reported in: http://marc.info/?l=linux-sparc&m=117407453208101&w=2 Anyways, fix this by using page_address(sgl.page) which is OK because we know this is low-mem due to GFP_ATOMIC.

The original check for WP-works-ok was in access_ok(), but got moved during the 2.5 series to fix a race vs. swap. Return the number of bytes to copy in the case where we are in an atomic region, so the non atomic code pathes in file_read_actor() and pipe_read() are taken. This could be optimized to avoid the kmap_atomicby moving the check for WP-works-ok into fault_in_pages_writeable(), but this is more intrusive and can be done later.

The problem occurs since the microcode driver uses request_firmware() in its CPU hotplug notifier, which is called after tasks has been frozen and hangs.

As a result we commit to disk not uptodate page content witch contains garbage from previous usage." and "Unexpected file size increasing." Call trace the same as it was in first issue but result is different. For example we have file with i_size is zero. we want write two blocks , but fs has only one free block. ->ext3_prepare_write(...from == 0, to == 2048) retry: ->block_prepare_write() == -ENOSPC# we failed but allocated one block here. ->ext3_prepare_failure() ->commit_write( from == 0, to == 1024) # after this i_size becomes 1024 :) if (ret == -ENOSPC && ext3_should_retry_alloc(inode->i_sb, &retries)) goto retry; Finally when all retries will be spended ext3_prepare_failure return -ENOSPC, but i_size was increased and later block trimm procedures can't help here.

Stack randomization will result in the memory stack starting at a lower address than this, and if the user has set a low stack limit with "ulimit -s", then you can end up with the register stack above the memory stack (or if you were very unlucky right on top of it!).

But holepunching gets no chance to clear that flag at the start of vmtruncate_range, so it's always set (unless a truncate came just before), so holepunch almost always does this second truncate_inode_pages_range. shmem holepunch has unlikely swap<->file races hereabouts whatever we do (without a fuller rework than is fit for this release): I was going to skip the second truncate in the punch_hole case, but Miklos points out that would make holepunch correctness more vulnerable to swapoff. So keep the second truncate, but follow it by an unmap_mapping_range to eliminate the disconnected pages (freed from pagecache while still mapped in userspace) that it might have left behind.

Hold info->lock throughout when holepunching? No, any user could prevent rescheduling for far too long. Instead take info->lock just when needed: in shmem_free_swp when removing the swap entries, and whenever removing a directory page from the level above. But so long as we remove before scanning, we can safely skip taking the lock at the lower levels, except at misaligned start and end of the hole.

Indeed, and it can also cause data loss beyond the hole. Fix this as in the patch proposed by Miklos, but distinguish between "limit" (how far we need to search: ignore truncation's next_index optimization in the holepunch case - if there are races it's more consistent to act on the whole range specified) and "upper_limit" (how far we can free directory pages: generally we must be careful to keep partially punched pages, but can relax at end of file - i_size being held stable by i_mutex).

When device-mapper's DM_DEV_CREATE_CMD ioctl is called to create a new device, dev_create()->dm_create()->alloc_dev()-> blk_queue_bounce_limit(md->queue, BLK_BOUNCE_ANY) is called. blk_queue_bounce_limit(BLK_BOUNCE_ANY) calls init_emergency_isa_pool() if blk_max_pfn < blk_max_low_pfn. This is the case on UML, but init_emergency_isa_pool() hits BUG_ON(!isa_page_pool) because there doesn't seem to be a dma zone on UML for mempool_create() to allocate from. Most architectures seem to have max_low_pfn == max_pfn, but UML doesn't because of the uml_reserved chunk it keeps for itself. From what I can see, max_pfn and max_low_pfn don't get much use after the bootmem-allocator stops being used anyway, except that they initialize the block layer's blk_max_low_pfn/blk_max_pfn. This ensures init_emergency_isa_pool() doesn't crash uml in this situation by setting max_low_pfn == max_pfn in mem_init().
