2010-09-29pcmcia: convert pcmcia_request_configuration to pcmcia_enable_deviceDominik Brodowski
pcmcia_enable_device() now replaces pcmcia_request_configuration(). Instead of config_req_t, all necessary flags are either passed as a parameter to pcmcia_enable_device(), or (in rare circumstances) set in struct pcmcia_device -> flags. With the last remaining user of include/pcmcia/cs.h gone, remove all references.

2010-09-29pcmcia: simplify IntTypeDominik Brodowski
IntType was only set to INT_MEMORY (driver pcmciamtd) or INT_MEMORY_AND_IO (all other drivers). As this flags seems to relate to ioport access, make it conditional to the driver having requested IO port access. There are two drivers which do not request IO ports, but did set INT_MEMORY_AND_IO: ray_cs and b43. For those, we consistently only set INT_MEMORY in future.

2010-09-29pcmcia: simplify Status, ExtStatus register accessDominik Brodowski
The Status (CISREG_CCSR) and ExtStatus (CISREG_ESR) registers were only accessed to enable audio output for some drivers and IRQ for serial_cs.c. The former also required setting config_req_t.Attributes to CONF_ENABLE_SPKR; the latter can be simplified to setting this field to CONF_ENABLE_ESR.

2010-09-29initramfs: fix initramfs size calculationHendrik Brueckner
The size of a built-in initramfs is calculated in init/initramfs.c by "__initramfs_end - __initramfs_start". Those symbols are defined in the linker script include/asm-generic/vmlinux.lds.h: #define INIT_RAM_FS \ . = ALIGN(PAGE_SIZE); \ VMLINUX_SYMBOL(__initramfs_start) = .; \ *(.init.ramfs) \ VMLINUX_SYMBOL(__initramfs_end) = .; If the initramfs file has an odd number of bytes, the "__initramfs_end" symbol points to an odd address, for example, the symbols in the System.map might look like: 0000000000572000 T __initramfs_start 00000000005bcd05 T __initramfs_end <-- odd address At least on s390 this causes a problem: Certain s390 instructions, especially instructions for loading addresses (larl) or branch addresses must be on even addresses. The compiler loads the symbol addresses with the "larl" instruction. This instruction sets the last bit to 0 and, therefore, for odd size files, the calculated size is one byte less than it should be: 0000000000540a9c <populate_rootfs>: 540a9c: eb cf f0 78 00 24 stmg %r12,%r15,120(%r15), 540aa2: c0 10 00 01 8a af larl %r1,572000 <__initramfs_start> 540aa8: c0 c0 00 03 e1 2e larl %r12,5bcd04 <initramfs_end> (Instead of 5bcd05) ... 540abe: 1b c1 sr %r12,%r1 To fix the problem, this patch introduces the global variable __initramfs_size, which is calculated in the "usr/initramfs_data.S" file. The populate_rootfs() function can then use the start marker of the .init.ramfs section and the value of __initramfs_size for loading the initramfs. Because the start marker and size is sufficient, the __initramfs_end symbol is no longer needed and is removed.

2010-09-28ipv4: Allow configuring subnets as local addressesTom Herbert
This patch allows a host to be configured to respond to any address in a specified range as if it were local, without actually needing to configure the address on an interface. This is done through routing table configuration. For instance, to configure a host to respond to any address in 10.1/16 received on eth0 as a local address we can do: ip rule add from all iif eth0 lookup 200 ip route add local 10.1/16 dev lo proto kernel scope host src 127.0.0.1 table 200 This host is now reachable by any 10.1/16 address (route lookup on input for packets received on eth0 can find the route). On output, the rule will not be matched so that this host can still send packets to 10.1/16 (not sent on loopback). Presumably, external routing can be configured to make sense out of this. To make this work, we needed to modify the logic in finding the interface which is assigned a given source address for output (dev_ip_find). We perform a normal fib_lookup instead of just a lookup on the local table, and in the lookup we ignore the input interface for matching. This patch is useful to implement IP-anycast for subnets of virtual addresses. Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-09-28netfilter: ctnetlink: add support for user-space expectation helpersPablo Neira Ayuso
This patch adds the basic infrastructure to support user-space expectation helpers via ctnetlink and the netfilter queuing infrastructure NFQUEUE. Basically, this patch: * adds NF_CT_EXPECT_USERSPACE flag to identify user-space created expectations. I have also added a sanity check in __nf_ct_expect_check() to avoid that kernel-space helpers may create an expectation if the master conntrack has no helper assigned. * adds some branches to check if the master conntrack helper exists, otherwise we skip the code that refers to kernel-space helper such as the local expectation list and the expectation policy. * allows to set the timeout for user-space expectations with no helper assigned. * a list of expectations created from user-space that depends on ctnetlink (if this module is removed, they are deleted). * includes USERSPACE in the /proc output for expectations that have been created by a user-space helper. This patch also modifies ctnetlink to skip including the helper name in the Netlink messages if no kernel-space helper is set (since no user-space expectation has not kernel-space kernel assigned).

2010-09-27net: Allow changing number of RX queues after device allocationBen Hutchings
For RPS, we create a kobject for each RX queue based on the number of queues passed to alloc_netdev_mq(). However, drivers generally do not determine the numbers of hardware queues to use until much later, so this usually represents the maximum number the driver may use and not the actual number in use. For TX queues, drivers can update the actual number using netif_set_real_num_tx_queues(). Add a corresponding function for RX queues, netif_set_real_num_rx_queues().

Fixes kernel bugzilla #16603 tcp_sendmsg() truncates iov_len to an 'int' which a 4GB write to write zero bytes, for example. There is also the problem higher up of how verify_iovec() works. It wants to prevent the total length from looking like an error return value. However it does this using 'int', but syscalls return 'long' (and thus signed 64-bit on 64-bit machines). So it could trigger false-positives on 64-bit as written. So fix it to use 'long'.

2010-09-27V4L/DVB: videobuf-dma-sg: set correct size in last sg elementHans Verkuil
This fixes a nasty memory corruption bug when using userptr I/O. The function videobuf_pages_to_sg() sets up the scatter-gather list for the DMA transfer to the userspace pages. The first transfer is setup correctly (the size is set to PAGE_SIZE - offset), but all other transfers have size PAGE_SIZE. This is wrong for the last transfer which may be less than PAGE_SIZE. Most, if not all, drivers will program the boards DMA engine correctly, i.e. even though the size in the last sg element is wrong, they will do their own size calculations and make sure the right amount is DMA-ed, and so seemingly prevent memory corruption. However, behind the scenes the dynamic DMA mapping support (in lib/swiotlb.c) may create bounce buffers if the memory pages are not in DMA-able memory. This happens for example on a 64-bit linux with a board that only supports 32-bit DMA. These bounce buffers DO use the information in the sg list to determine the size. So while the DMA engine transfers the correct amount of data, when the data is 'bounced' back too much is copied, causing buffer overwrites. The fix is simple: calculate and set the correct size for the last sg list element.

2010-09-27mac80211: move packet flags into packetJohannes Berg
commit 8c0c709eea5cbab97fb464cd68b06f24acc58ee1 Author: Johannes Berg <johannes@sipsolutions.net> Date: Wed Nov 25 17:46:15 2009 +0100 mac80211: move cmntr flag out of rx flags moved the CMNTR flag into the skb RX flags for some aggregation cleanups, but this was wrong since the optimisation this flag tried to make requires that it is kept across the processing of multiple interfaces -- which isn't true for flags in the skb. The patch not only broke the optimisation, it also introduced a bug: under some (common!) circumstances the flag will be set on an already freed skb! However, investigating this in more detail, I found that most of the flags that we set should be per packet, _except_ for this one, due to a-MPDU processing. Additionally, the flags used for processing (currently just this one) need to be reset before processing a new packet. Since we haven't actually seen bugs reported as a result of the wrong flags handling (which is not too surprising -- the only real bug case I can come up with is an a-MSDU contained in an a-MPDU), I'll make a different fix for rc.

These GPEs are then almost immediately disabled by the ACPI namespace scanning code with the help of acpi_gpe_can_wake(), but it would be better not to enable them at all until really necessary. Modify the initialization of GPEs so that the ones that have associated _Lxx or _Exx methods and are not pointed to by any _PRW methods will be enabled after the namespace scan is complete.

Because ieee80211_handle_filtered_frame feeds skbs back into the tx path, they have to be stripped of some tx flags so they won't confuse the stack, driver or device.

2010-09-24net: davinci_emac: switch to new mdioCyril Chemparathy
This patch switches the emac implementation over to the newly separated MDIO driver. With this, the mdio bus frequency defaults to a safe 2.2MHz. Boards may optionally specify a bus frequency via platform data. The phy identification scheme has been modified to use a phy bus id instead of a mask. This largely serves to eliminate the "phy search" code in emac init. Signed-off-by: Cyril Chemparathy <cyril@ti.com> Acked-by: David S.

2010-09-24net: davinci_emac: separate out davinci mdioCyril Chemparathy
Davinci's MDIO controller is present on other TI devices, without an accompanying EMAC. For example, on tnetv107x, the same MDIO module is used in conjunction with a 3-port switch hardware. By separating the MDIO controller code into its own platform driver, this patch allows common logic to be reused on such platforms.

2010-09-24NFSv4.1: keep seq_res.sr_slot as pointer rather than an indexBenny Halevy
Having to explicitly initialize sr_slotid to NFS4_MAX_SLOT_TABLE resulted in numerous bugs. Keeping the current slot as a pointer to the slot table is more straight forward and robust as it's implicitly set up to NULL wherever the seq_res member is initialized to zeroes.
