H.323 connection tracking code calls ip_ct_refresh_acct() when processing RCFs and URQs but passes NULL as the skb. When CONFIG_IP_NF_CT_ACCT is enabled, the connection tracking core tries to derefence the skb, which results in an obvious panic. A similar fix was applied on the SIP connection tracking code some time ago. Signed-off-by:

Drain the Microcode TX-status-FIFO before we enable IRQs. This is required, because the FIFO may still have entries left from a previous run. Those would immediately fire after enabling IRQs and would lead to an oops in the DMA TXstatus handling code. Cc: "John W. Linville" <linville@tuxdriver.com> Signed-off-by:

For policy routing, packets originating from this machine itself may be routed differently to packets passing through. We want this packet to be routed as if it came from this machine itself. So re-compute the routing information using ip_route_me_harder(). This patch is derived from work by Ken Brownfield This patch (-stable version) also includes commit b4c4ed17 ([NETFILTER]: add type parameter to ip_route_me_harder), which is a precondition for the fix.

Backport fix for missing ruleset validation in {arp,ip,ip6}_tables and a fix on top which fixes a regression in the first patch. There is a number of issues in parsing user-provided table in translate_table(). Malicious user with CAP_NET_ADMIN may crash system by passing special-crafted table to the *_tables. The first issue is that mark_source_chains() function is called before entry content checks. In case of standard target, mark_source_chains() function uses t->verdict field in order to determine new position. But the check, that this field leads no further, than the table end, is in check_entry(), which is called later, than mark_source_chains(). The second issue, that there is no check that target_offset points inside entry. If so, *_ITERATE_MATCH macro will follow further, than the entry ends. As a result, we'll have oops or memory disclosure. And the third issue, that there is no check that the target is completely inside entry. Results are the same, as in previous issue. Upstream commit 590bdf7f introduced a regression in match/target hook validation. mark_source_chains builds a bitmask for each rule representing the hooks it can be reached from, which is then used by the matches and targets to make sure they are only called from valid hooks. The patch moved the match/target specific validation before the mark_source_chains call, at which point the mask is always zero. This patch returns back to the old order and moves the standard checks to mark_source_chains. This allows to get rid of a special case for standard targets as a nice side-effect. Signed-off-by: -

The 32bit compatibility layer has no CAP_NET_ADMIN check in compat_do_ipt_get_ctl, which for example allows to list the current iptables rules even without having that capability (the non-compat version requires it). Other capabilities might be required to exploit the bug (eg. CAP_NET_RAW to get the nfnetlink socket?), so a plain user can't exploit it, but a setup actually using the posix capability system might very well hit such a constellation of granted capabilities.

ATAPI devices transfer fixed number of bytes for CDBs (12 or 16). Some ATAPI devices choke when shorter CDB is used and the left bytes contain garbage. Block SG_IO cleared left bytes but SCSI SG_IO didn't. This patch makes SCSI SG_IO clear it and simplify CDB clearing in block SG_IO. Signed-off-by:

The PCI sysfs attributes are created after the initial PCI bus scan. With the addition of more return value checking and assertions in the device and sysfs layers we now can get dumps like this on sparc64: [ 20.135032] Call Trace: [ 20.135042] [0000000000537f88] pci_remove_bus_device+0x30/0xc0 [ 20.135076] [000000000078f890] pci_fill_in_pbm_cookies+0x98/0x440 [ 20.135109] [000000000042e828] sabre_scan_bus+0x230/0x400 [ 20.135139] [000000000078c710] pcibios_init+0x58/0xa0 [ 20.135159] [0000000000416f14] init+0x9c/0x2e0 [ 20.135190] [0000000000417a50] kernel_thread+0x38/0x60 [ 20.135211] [0000000000417170] rest_init+0x18/0x40 [ 20.135514] PCI0(PBMB): Bus running at 33MHz It's triggering because removal of the "config" PCI sysfs file for the device fails. On sparc64, after probing the device, we'll delete the PCI device via pci_remove_bus_device() if we cannot find the firmware device tree node corresponding to it. This is fine, but at this point the sysfs files for the PCI device won't be setup yet. So we should not try to do anything in pci_remove_sysfs_dev_files() if pci_sysfs_init() has not run yet.

initlvl=2 in seclvl gives the guarantee "Cannot decrement the system time". But it was possible to set the time to the maximum unixtime value (19 Jan 2038) resulting in a wrap to the minimum value. This patch fixes this by disallowing setting the time to any date after 2030 with initlvl=2. This patch does not apply to kernel 2.6.19 since the seclvl module was already removed in this kernel.

similar to the version in adbhid_input_register(): The '<>' key and the '^°' key on a german keyboard is swapped. Provide correct keys to userland, external USB keyboards will not work correctly when the 'badmap'/'goodmap' workarounds from xkeyboard-config are used. It is expected that distributions drop the badmap/goodmap part from keycodes/macintosh in the xkeyboard-config package. This is probably 2.6.18.x material, if major distros settle on 2.6.18.

This reverts an earlier patch that was found to cause FPU state corruption. I think the corruption happens because unlazy_fpu() can cause FPU exceptions and when it happens after the current switch some processing would affect the state in the wrong process.

We have seen a couple of __alloc_pages() failures due to fragmentation, there is plenty of free memory but no large order pages available.

It looks like there is a bug in init_reap_node() in slab.c that can cause multiple oops's on certain ES7000 configurations. The variable reap_node is defined per cpu, but only initialized on a single CPU. This causes an oops in next_reap_node() when __get_cpu_var(reap_node) returns the wrong value. Fix is below.

ufs2 fails to mount on x86_64, claiming bad magic. This is because ufs_super_block_third's fs_un1 member is padded out by 4 bytes for 8-byte alignment, pushing down the rest of the struct. Forcing this to be packed solves it. I took a quick look over other on-disk structures and didn't immediately find other problems. I was able to mount & ls a populated ufs2 filesystem w/ this change.

When I added the robust futex syscall entries I forgot to bump NR_SYSCALLS. This is an easy mistake to make because NR_SYSCALLS lived in entry.S which is nowhere near unistd.h or syscalls.S, so while we're here move it's definition into unistd.h so this is unlikely to ever happen again.

sys_move_pages() uses vmalloc() to allocate an array of structures that is fills with information passed from user mode and then passes to do_stat_pages() (in the case the node list is NULL). do_stat_pages() depends on a marker in the node field of the structure to decide how large the array is and this marker is correctly inserted into the last element of the array. However, vmalloc() doesn't zero the memory it allocates and if the user passes NULL for the node list, then the node fields are not filled in (except for the end marker). If the memory the vmalloc() returned happend to have a word with the marker value in it in just the right place, do_pages_stat will fail to fill the status field of part of the array and we will return (random) kernel data to user mode.
