2012-05-19ALSA: hda - Fix possible races of accesses to connection list arrayTakashi Iwai
Like the previous fixes for cache hash accesses, a protection over accesses to the widget connection list array must be provided. Together with this action, remove snd_hda_get_conn_list() which can be always race, and replace it with either snd_hda_get_num_conns() or snd_hda_get_connections() calls.

2012-05-19ipv6: disable GSO on sockets hitting dst_allfragEric Dumazet
If the allfrag feature has been set on a host route (due to an ICMPv6 Packet Too Big received indicating a MTU of less than 1280), we hit a very slow behavior in TCP stack, because all big packets are dropped and only a retransmit timer is able to push one MSS frame every 200 ms. One way to handle this is to disable GSO on the socket the first time a super packet is dropped. Adding a specific dst_allfrag() in the fast path is probably overkill since the dst_allfrag() case almost never happen.

2012-05-18ipv6: ip6_fragment() should check CHECKSUM_PARTIALEric Dumazet
Quoting Tore Anderson from : If the allfrag feature has been set on a host route (due to an ICMPv6 Packet Too Big received indicating a MTU of less than 1280), TCP SYN/ACK packets to that destination appears to get an incorrect TCP checksum. This in turn means they are thrown away as invalid. In the case of an IPv4 client behind a link with a MTU of less than 1260, accessing an IPv6 server through a stateless translator, this means that the client can only download a single large file from the server, because once it is in the server's routing cache with the allfrag feature set, new TCP connections can no longer be established. </endquote> It appears ip6_fragment() doesn't handle CHECKSUM_PARTIAL properly. As network drivers are not prepared to fetch correct transport header, a safe fix is to call skb_checksum_help() before fragmenting packet.

GNU ld 2.22.52.0.1 has a bug that it blindly changes symbols from section-relative to absolute if they are in a section of zero length.

2012-05-18x86, realmode: 16-bit real-mode code support for relocs toolH. Peter Anvin
A new option is added to the relocs tool called '--realmode'. This option causes the generation of 16-bit segment relocations and 32-bit linear relocations for the real-mode code. When the real-mode code is moved to the low-memory during kernel initialization, these relocation entries can be used to relocate the code properly. In the assembly code 16-bit segment relocations must be relative to the 'real_mode_seg' absolute symbol. Linear relocations must be relative to a symbol prefixed with 'pa_'. 16-bit segment relocation is used to load cs:ip in 16-bit code. Linear relocations are used in the 32-bit code for relocatable data references. They are declared in the linker script of the real-mode code. The relocs tool is moved to arch/x86/tools/relocs.c, and added new target archscripts that can be used to build scripts needed building an architecture. be compiled before building the arch/x86 tree. [ hpa: accelerating this because it detects invalid absolute relocations, a serious bug in binutils 2.22.52.0.x which currently produces bad kernels. ] Signed-off-by: H.

We need to use a different loop index for mlx4_counter_alloc() and for device_create_file() iterations: the mlx4_counter_alloc() loop index is used in the error flow to free counters. If the same loop index is used for device_create_file() and, say, the device_create_file() loop fails on the first iteration, the allocated counters will not be freed.

2012-05-18staging: comedi: cleanup all the comedi_driver 'detach' functionsH Hartley Sweeten
1. Change the return type from int to void All the detach functions, except for the comedi usb drivers, simply return success (0). Plus, the return code is never checked in the comedi core. The comedi usb drivers do return error codes but the conditions can never happen. The first check is: if (!dev) return -EFAULT; This checks that the passed comedi_device pointer is valid. The detach function itself is called using this pointer so it MUST always be valid or there is a bug in the core: if (dev->driver) dev->driver->detach(dev); And the second check: usb = dev->private; if (!usb) return -EFAULT; The dev->private pointer is setup in the attach function to point to the probed usb device. This value could be NULL if the attach fails. But, since the comedi core is going to unload the driver anyway and does not check for errors there is no gain by returning one. After removing these checks from the comedi usb drivers the detach functions required a bit of cleanup. 2. Remove all the printk noise in the detach functions All of the printk output is really just noise. The user did a rmmod to unload the driver, we really don't need to tell them about it. Also, some of the messages are output using: dev_dbg(dev->hw_dev, ... or dev_info(dev->hw_dev, ... Unfortunately the hw_dev value is only used by drivers that are doing DMA. For most drivers this variable is going to be NULL so the output is not going to work as expected. 3. Refactor a couple static 'free_resource' functions into the detach functions. The 'free_resource' function is only being called by the detach and it makes more sense to just absorb the code. 4. Remove a couple unnecessary braces for single statements. 5. Remove unnecessary comments. Most of the comedi drivers appear to be based on the comedi skel driver and have the comments from that driver included. These comments make sense in the skel driver for reference but they don't need to be in any of the actual drivers. 6. Remove all the extra whitespace. It's not needed to make the functions any more readable. 7. Remove the now unused 'attached_successfully' variable in the cb_pcimdda driver. This variable was only used to conditionally output some driver noise during the detach. Since all the printk's have been removed this variable is no longer necessary.
