Problem is that network stack arranges for the locally generated broadcasts to appear on the interface they were sent out, so the IFF_LOOPBACK check doesn't trigger. As -m rpfilter is restricted to PREROUTING, we can check for existing rtable instead, it catches locally-generated broad/multicast case, too.

This is wrong and unnecessary. nf_reset() is used in the following cases: - when passing packets up the the socket layer, at which point we want to release all netfilter references that might keep modules pinned while the packet is queued. nf_trace doesn't matter anymore at this point. - when encapsulating or decapsulating IPsec packets. We want to continue tracing these packets after IPsec processing. - when passing packets through virtual network devices. Only devices on that encapsulate in IPv4/v6 matter since otherwise nf_trace is not used anymore. Its not entirely clear whether those packets should be traced after that, however we've always done that. - when passing packets through virtual network devices that make the packet cross network namespace boundaries. This is the only cases where we clearly want to reset nf_trace and is also what the original patch intended to fix. Add a new function nf_reset_trace() and use it in dev_forward_skb() to fix this properly. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

The code was calling blkdev_issue_discard and specifying the correct sector offset and sector size, but blkdev_issue_discard expects these values to be in terms of 512 byte sectors, even if the native sector size for the device is different. Calling sb_issue_discard with the BLOCK size instead ensures the correct block-to-512b-sector translation.

The problem was that the first send was before the socket was accepted and thus sock->sk_socket was NULL in maybe_add_creds, and the second send after the socket was accepted had a non-NULL value for sk->socket and thus we could tell the credentials were not needed so we did not bother. The unnecessary credentials on the first message cause unix_stream_recvmsg to start verifying that all messages had the same credentials before coallescing and then the coallescing failed because the second message had no credentials. Ignoring credentials when we don't care in unix_stream_recvmsg fixes a long standing pessimization which would fail to coallesce messages when reading from a unix stream socket if the senders were different even if we did not care about their credentials. I have tested this and verified that the in the LSB test case mentioned above that the messages do coallesce now, while the were failing to coallesce without this change.

As for the iwlwifi bits, Johannes says: "The only fix here is to the passive-no-RX firmware regulatory enforcement driver support code to not drop auth frames in quick succession, leading to not being able to connect to APs on passive channels in certain circumstances." Don't forget the NFC bits, about which Samuel says: "This time we have: - A crash fix for when a DGRAM LLCP socket is listening while the NFC adapter is physically removed. - A potential double skb free when the LLCP socket receive queue is full. - A fix for properly handling multiple and consecutive LLCP connections, and not trash the socket ack log. - A build failure for the MEI microread physical layer, now that the MEI bus APIs have been merged into char-misc-next."

The commit [6ab317419c: ALSA: hda - Allow power_save_controller option override DCAPS] changed the behavior of power_save_controller so that it can override the driver capability. This assumed that this option is rarely changed dynamically unlike power_save option. Too naive. It turned out that the user-space power-management tool tries to set power_save_controller option to 1 together with power_save option without knowing what's actually doing. This enabled forcibly the runtime PM of the controller, which is known to be broken om many chips thus disabled as default. So, the only sane fix is to revert this commit again. It was intended to ease debugging/testing for runtime PM enablement, but obviously we need another way for it.

Commit 6248d06 (ARM: 7545/1: cache-l2x0: make outer_cache_fns a field of l2x0_of_data) changed how .set_debug is initialized. Both commits break commit 74ddcdb (ARM: 7608/1: l2x0: Only set .set_debug on PL310 r3p0 and earlier) which uses the RTL version to conditionally set .set_debug function pointer. Commit b8db6b8 also caused the printed cache ID to be missing the version information. Fix this by reverting how the part number is masked so the RTL version info is maintained. The cache-id-part DT property does not set the RTL bits so masking them should have no effect. Also, re-arrange the order of the function pointer init so the .set_debug function can be overridden.

The same behavior is observed in other UAC2 hardware like the VIA VT1731. Reset the interface after setting the sampling frequency on sample rate changes, to ensure that the sample rate set by snd_usb_init_sample_rate() is used. Otherwise, the device will try to use the sample rate of the previous stream, causing distorted sound on sample rate changes. The reset is performed for all UAC2 devices, as it should not affect a standards compliant device, but it is only necessary for C-Media CM6631, VIA VT1731 and possibly others.

| 25fb6ca | Balakumaran Kannan | 02 April 2013, 10:45:05 UTC | net IPv6 : Fix broken IPv6 routing table after loopback down-up IPv6 Routing table becomes broken once we do ifdown, ifup of the loopback(lo) interface. After down-up, routes of other interface's IPv6 addresses through 'lo' are lost. IPv6 addresses assigned to all interfaces are routed through 'lo' for internal communication. Once 'lo' is down, those routing entries are removed from routing table. But those removed entries are not being re-created properly when 'lo' is brought up. So IPv6 addresses of other interfaces becomes unreachable from the same machine. Also this breaks communication with other machines because of NDISC packet processing failure. This patch fixes this issue by reading all interface's IPv6 addresses and adding them to IPv6 routing table while bringing up 'lo'. ==Testing== Before applying the patch: $ route -A inet6 Kernel IPv6 routing table Destination Next Hop Flag Met Ref Use If 2000::20/128 :: U 256 0 0 eth0 fe80::/64 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo ::1/128 :: Un 0 1 0 lo 2000::20/128 :: Un 0 1 0 lo fe80::xxxx:xxxx:xxxx:xxxx/128 :: Un 0 1 0 lo ff00::/8 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo $ sudo ifdown lo $ sudo ifup lo $ route -A inet6 Kernel IPv6 routing table Destination Next Hop Flag Met Ref Use If 2000::20/128 :: U 256 0 0 eth0 fe80::/64 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo ::1/128 :: Un 0 1 0 lo ff00::/8 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo $ After applying the patch: $ route -A inet6 Kernel IPv6 routing table Destination Next Hop Flag Met Ref Use If 2000::20/128 :: U 256 0 0 eth0 fe80::/64 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo ::1/128 :: Un 0 1 0 lo 2000::20/128 :: Un 0 1 0 lo fe80::xxxx:xxxx:xxxx:xxxx/128 :: Un 0 1 0 lo ff00::/8 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo $ sudo ifdown lo $ sudo ifup lo $ route -A inet6 Kernel IPv6 routing table Destination Next Hop Flag Met Ref Use If 2000::20/128 :: U 256 0 0 eth0 fe80::/64 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo ::1/128 :: Un 0 1 0 lo 2000::20/128 :: Un 0 1 0 lo fe80::xxxx:xxxx:xxxx:xxxx/128 :: Un 0 1 0 lo ff00::/8 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo $ Signed-off-by: Balakumaran Kannan <Balakumaran.Kannan@ap.sony.com> Signed-off-by: Maruthi Thotad <Maruthi.Thotad@ap.sony.com> Signed-off-by: David S.

Consequently, acpi_i2c_register_devices() should use the ACPI handle of the parent of the struct i2c_adapter it is called for rather than the struct i2c_adapter's ACPI handle (which should be NULL).

| ea81531 | Heiko Carstens | 21 March 2013, 11:50:39 UTC | s390/uaccess: fix page table walk When translating user space addresses to kernel addresses the follow_table() function had two bugs: - PROT_NONE mappings could be read accessed via the kernel mapping. That is e.g. putting a filename into a user page, then protecting the page with PROT_NONE and afterwards issuing the "open" syscall with a pointer to the filename would incorrectly succeed. - when walking the page tables it used the pgd/pud/pmd/pte primitives which with dynamic page tables give no indication which real level of page tables is being walked (region2, region3, segment or page table). So in case of an exception the translation exception code passed to __handle_fault() is not necessarily correct. This is not really an issue since __handle_fault() doesn't evaluate the code. Only in case of e.g. a SIGBUS this code gets passed to user space. If user space can do something sane with the value is a different question though. To fix these issues don't use any Linux primitives. Only walk the page tables like the hardware would do it, however we leave quite some checks away since we know that we only have full size page tables and each index is within bounds. In theory this should fix all issues...

Wysocki | 01 April 2013, 00:21:08 UTC | ACPI / SPI: Use parent's ACPI_HANDLE() in acpi_register_spi_devices() The ACPI handle of struct spi_master's dev member should not be set, because this causes that struct spi_master to be associated with the ACPI device node corresponding to its parent as the second "physical_device", which is incorrect (this happens during the registration of struct spi_master). Consequently, acpi_register_spi_devices() should use the ACPI handle of the parent of the struct spi_master it is called for rather than that struct spi_master's ACPI handle (which should be NULL). Make that happen and modify the spi-pxa2xx driver, which currently is the only driver for ACPI-enumerated SPI controller chips, not to set the ACPI handle for the struct spi_master it creates.

When we create the device "losetup /dev/loopXX afile" we want that block_device stay alive until we destroy the loop device with "losetup -d". But because we do not hold /dev/loopXX inode its counter goes 0, and inode/bdev can be destroyed at any moment. Usually it happens at memory pressure or when user drops inode cache (like in the test below). When later in loop_clr_fd() we want to use bdev we have use-after-free error with following stack: BUG: unable to handle kernel NULL pointer dereference at 0000000000000280 bd_set_size+0x10/0xa0 loop_clr_fd+0x1f8/0x420 [loop] lo_ioctl+0x200/0x7e0 [loop] lo_compat_ioctl+0x47/0xe0 [loop] compat_blkdev_ioctl+0x341/0x1290 do_filp_open+0x42/0xa0 compat_sys_ioctl+0xc1/0xf20 do_sys_open+0x16e/0x1d0 sysenter_dispatch+0x7/0x1a To prevent use-after-free we need to grab the device in loop_set_fd() and put it later in loop_clr_fd().
