Up until this point we've accepted replay window settings greater than 32 but our bit mask can only accomodate 32 packets. Thus any packet with a sequence number within the window but outside the bit mask would be accepted. This patch causes those packets to be rejected instead.

When we receive an AppleTalk frame shorter than what its header says, we still attempt to verify its checksum, and trip on the BUG_ON() at the end of function atalk_sum_skb() because of the length mismatch. 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: <Appletalk Killer> { # 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: NJean Delvare <jdelvare@suse.de> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

In debugging a problem w/ the -rt tree, I noticed that on systems that mark the tsc as unstable before it is registered, the TSC would still be selected and used for a short period of time. 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.

Revert all this. It can cause device-mapper to receive a different major from earlier kernels and it turns out that the Amanda backup program (via GNU tar, apparently) checks major numbers on files when performing incremental backups.

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. This patch which just ignores errors should be safe and it keeps the system from going completely wacky. Signed-off-by: NEric W.

The git commit c2fda5fe which added the page_test_and_clear_dirty call to page_mkclean and the git commit 7658cc28 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. Signed-off-by: NMartin Schwidefsky <schwidefsky@de.ibm.com>

Current 2.6.21 libata does the following: void ata_tf_read(struct ata_port *ap, struct ata_taskfile *tf) { struct ata_ioports *ioaddr = &ap->ioaddr; tf->command = ata_check_status(ap); ... if (tf->flags & ATA_TFLAG_LBA48) { iowrite8(tf->ctl | ATA_HOB, ioaddr->ctl_addr); tf->hob_feature = ioread8(ioaddr->error_addr); ... } } ... static void fill_result_tf(struct ata_queued_cmd *qc) { struct ata_port *ap = qc->ap; ap->ops->tf_read(ap, &qc->result_tf); qc->result_tf.flags = qc->tf.flags; } Based on this, those last two statements fill_result_tf() appear to me to be in the wrong order, in that the tf->flags are uninitialized at the point where tf_read() is invoked. So for lba48 commands, tf_read() won't be reading back the full lba48 register contents.. Correct? This patch corrects fill_result_tf() so that the flags get copied to result_tf before they are used by tf_read().

If you set the IFF_ALLMULTI flag on a b44 device, or if you join more than B44_MCAST_TABLE_SIZE multicast groups, the device will stop receiving unicast messages. This is because the __b44_set_mac_addr call sets the zeroth CAM entry to the MAC address of the device, and then the loop at line 1722 proceeds to overwrite it unless the value of i is set by the __b44_load_mcast call. However, when IFF_ALLMULTI is set, that call is bypassed, leaving i set to zero. Fixed by starting the loop at 1 to make it skip the CAM entry for the MAC address.

由 Eric W. Biederman 提交于
This is a simplified and actually more comprehensive form of a bug fix from Mitch Williams <mitch.a.williams@intel.com>. 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.

This fixes a regression caused by commit: 2dc611de The sense buffer code in scsi_send_eh_cmnd was changed to use alloc_page() and a scatter list, but the sense data copy was not updated to match so what we actually get in the sense buffer is total grabage starting with the kernel address of the struct page we got. 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.
