* [UDP]: Introduce UDP encapsulation type for L2TPJames Chapman2007-07-11
| | | | | | | | | | | | | | | | | | This patch adds a new UDP_ENCAP_L2TPINUDP encapsulation type for UDP sockets. When a UDP socket's encap_type is UDP_ENCAP_L2TPINUDP, the skb is delivered to a function pointed to by the udp_sock's encap_rcv funcptr. If the skb isn't wanted by L2TP, it returns >0, which causes it to be passed through to UDP. Include padding to put the new encap_rcv field on a 4-byte boundary. Previously, the only user of UDP encap sockets was ESP, so when CONFIG_XFRM was not defined, some of the encap code was compiled out. This patch changes that. As a result, udp_encap_rcv() will now do a little more work when CONFIG_XFRM is not defined. Signed-off-by: James Chapman <jchapman@katalix.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NET]: dev: secondary unicast address supportPatrick McHardy2007-07-11
| | | | | | | | | | | | Add support for configuring secondary unicast addresses on network devices. To support this devices capable of filtering multiple unicast addresses need to change their set_multicast_list function to configure unicast filters as well and assign it to dev->set_rx_mode instead of dev->set_multicast_list. Other devices are put into promiscous mode when secondary unicast addresses are present. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

* [NET]: IPV6 checksum offloading in network devicesStephen Hemminger2007-07-11
| | | | | | | | | | | | | | | The existing model for checksum offload does not correctly handle devices that can offload IPV4 and IPV6 only. The NETIF_F_HW_CSUM flag implies device can do any arbitrary protocol. This patch: * adds NETIF_F_IPV6_CSUM for those devices * fixes bnx2 and tg3 devices that need it * add NETIF_F_IPV6_CSUM to ipv6 output (incl GSO) * fixes assumptions about NETIF_F_ALL_CSUM in nat * adjusts bridge union of checksumming computation Signed-off-by: David S.

* [IPV6] MIP6: Loadable module support for MIPv6.Masahide NAKAMURA2007-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes MIPv6 loadable module named "mip6". Here is a modprobe.conf(5) example to load it automatically when user application uses XFRM state for MIPv6: alias xfrm-type-10-43 mip6 alias xfrm-type-10-60 mip6 Some MIPv6 feature is not included by this modular, however, it should not be affected to other features like either IPsec or IPv6 with and without the patch. We may discuss XFRM, MH (RAW socket) and ancillary data/sockopt separately for future work. Loadable features: * MH receiving check (to send ICMP error back) * RO header parsing and building (i.e. RH2 and HAO in DSTOPTS) * XFRM policy/state database handling for RO These are NOT covered as loadable: * Home Address flags and its rule on source address selection * XFRM sub policy (depends on its own kernel option) * XFRM functions to receive RO as IPv6 extension header * MH sending/receiving through raw socket if user application opens it (since raw socket allows to do so) * RH2 sending as ancillary data * RH2 operation with setsockopt(2) Signed-off-by: Masahide NAKAMURA <nakam@linux-ipv6.org> Signed-off-by: David S.

* [RTNETLINK]: Add nested compat attributePatrick McHardy2007-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a nested compat attribute type that can be used to convert attributes that contain a structure to nested attributes in a backwards compatible way. The attribute looks like this: struct { [ compat contents ] struct rtattr { .rta_len = total size, .rta_type = type, } rta; struct old_structure struct; [ nested top-level attribute ] struct rtattr { .rta_len = nest size, .rta_type = type, } nest_attr; [ optional 0 .. n nested attributes ] struct rtattr { .rta_len = private attribute len, .rta_type = private attribute typ, } nested_attr; struct nested_data data; }; Since both userspace and kernel deal correctly with attributes that are larger than expected old versions will just parse the compat part and ignore the rest.

* [SKBUFF]: Keep track of writable header len of headerless clonesPatrick McHardy2007-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently NAT (and others) that want to modify cloned skbs copy them, even if in the vast majority of cases its not necessary because the skb is a clone made by TCP and the portion NAT wants to modify is actually writable because TCP release the header reference before cloning. The problem is that there is no clean way for NAT to find out how long the writable header area is, so this patch introduces skb->hdr_len to hold this length. When a headerless skb is cloned skb->hdr_len is set to the current headroom, for regular clones it is copied from the original. A new function skb_clone_writable(skb, len) returns whether the skb is writable up to len bytes from skb->data. To avoid enlarging the skb the mac_len field is reduced to 16 bit and the new hdr_len field is put in the remaining 16 bit. I've done a few rough benchmarks of NAT (not with this exact patch, but a very similar one). As expected it saves huge amounts of system time in case of sendfile, bringing it down to basically the same amount as without NAT, with sendmsg it only helps on loopback, probably because of the large MTU. Transmit a 1GB file using sendfile/sendmsg over eth0/lo with and without NAT: - sendfile eth0, no NAT: sys 0m0.388s - sendfile eth0, NAT: sys 0m1.835s - sendfile eth0: NAT + path: sys 0m0.370s (~ -80%) - sendfile lo, no NAT: sys 0m0.258s - sendfile lo, NAT: sys 0m2.609s - sendfile lo, NAT + patch: sys 0m0.260s (~ -90%) - sendmsg eth0, no NAT: sys 0m2.508s - sendmsg eth0, NAT: sys 0m2.539s - sendmsg eth0, NAT + patch: sys 0m2.445s (no change) - sendmsg lo, no NAT: sys 0m2.151s - sendmsg lo, NAT: sys 0m3.557s - sendmsg lo, NAT + patch: sys 0m2.159s (~ -40%) I expect other users can see a similar performance improvement, packet mangling iptables targets, ipip and ip_gre come to mind ..

* Make common helpers for seq_files that work with list_headsPavel Emelianov2007-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many places in kernel use seq_file API to iterate over a regular list_head. The code for such iteration is identical in all the places, so it's worth introducing a common helpers. This makes code about 300 lines smaller: The first version of this patch made the helper functions static inline in the seq_file.h header. This patch moves them to the fs/seq_file.c as Andrew proposed. The vmlinux .text section sizes are as follows: 2.6.22-rc1-mm1: 0x001794d5 with the previous version: 0x00179505 with this patch: 0x00179135 The config file used was make allnoconfig with the "y" inclusion of all the possible options to make the files modified by the patch compile plus drivers I have on the test node.

* Add LZO1X algorithm to the kernelRichard Purdie2007-07-10
| | | | | | | | | | | | | | | | | | | This is a hybrid version of the patch to add the LZO1X compression algorithm to the kernel. Nitin and myself have merged the best parts of the various patches to form this version which we're both happy with (and are jointly signing off). The performance of this version is equivalent to the original minilzo code it was based on. Bytecode comparisons have also been made on ARM, i386 and x86_64 with favourable results. There are several users of LZO lined up including jffs2, crypto and reiser4 since its much faster than zlib.

A new hook ata_acpi_on_suspend() is responsible for storing _GTM parameters during suspend. _STM is executed in ata_acpi_on_resume(). With this change, invoking _GTF is safe on IDE hierarchy and acpi_sata check before _GTF is removed. ata_acpi_gtm() and ata_acpi_stm() implementation is taken from Alan Cox's pata_acpi implementation. ata_acpi_gtm() is fixed such that the result parameter is not shifted by sizeof(union acpi_object).

These two functions are responsible for determining whether specific ACPI method is used and when. On resume, _GTF is scheduled by setting ATA_DFLAG_ACPI_PENDING device flag. This is done this way to avoid performing the action on wrong device device (device swapping while suspended). On every ata_dev_configure(), ata_acpi_on_devcfg() is called, which performs _SDD and _GTF. _GTF is performed only after resuming and, if SATA, hardreset as the ACPI spec specifies. As _GTF may contain arbitrary commands, IDENTIFY page is re-read after _GTF taskfiles are executed. If one of ACPI methods fails, ata_acpi_on_devcfg() retries on the first failure. If it fails again on the second try, ACPI is disabled on the device. Note that successful configuration clears ACPI failed status. With all feature checks moved to the above two functions, do_drive_set_taskfiles() is trivial and thus collapsed into ata_acpi_exec_tfs(), which is now static and converted to return the number of executed taskfiles to be used by ata_acpi_on_resume(). As failures are handled properly, ata_acpi_push_id() now returns -errno on errors instead of unconditional zero.

This is way safer and simpler.

| * | | [GFS2] Fix sign problem in quota/statfs and cleanup _host structuresSteven Whitehouse2007-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes some sign issues which were accidentally introduced into the quota & statfs code during the endianess annotation process. Also included is a general clean up which moves all of the _host structures out of gfs2_ondisk.h (where they should not have been to start with) and into the places where they are actually used (often only one place). Also those _host structures which are not required any more are removed entirely (which is the eventual plan for all of them). The conversion routines from ondisk.c are also moved into the places where they are actually used, which for almost every one, was just one single place, so all those are now static functions. This also cleans up the end of gfs2_ondisk.h which no longer needs the #ifdef __KERNEL__. The net result is a reduction of about 100 lines of code, many functions now marked static plus the bug fixes as mentioned above. For good measure I ran the code through sparse after making these changes to check that there are no warnings generated.

| * | | [DLM] cancel in conversion deadlock [4/6]David Teigland2007-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When conversion deadlock is detected, cancel the conversion and return EDEADLK to the application. This is a new default behavior where before the dlm would allow the deadlock to exist indefinately. The DLM_LKF_NODLCKWT flag can now be used in a conversion to prevent the dlm from performing conversion deadlock detection/cancelation on it. The DLM_LKF_CONVDEADLK flag can continue to be used as before to tell the dlm to demote the granted mode of the lock being converted if it gets into a conversion deadlock.

This "transaction id" will be used later to associate locks with each other during deadlock detection. - Add a "timeout" value for each lock. This is used along with the DLM_LKF_TIMEOUT flag. Also, remove a fragment of unused code in device_read(). This patch requires updating libdlm which is backward compatible with older kernels.

If the DLM_LKF_TIMEOUT flag is set, then the request/conversion will be canceled after waiting the specified number of centiseconds (specified per lock). This feature is only available for locks requested through libdlm (can be enabled for kernel dlm users if there's a use for it.) If the new DLM_LSFL_TIMEWARN flag is set when creating the lockspace, then a warning message will be sent to userspace (using genetlink) after a request/conversion has been waiting for a given number of centiseconds (configurable per node). The time warnings will be used in the future to do deadlock detection in userspace. Signed-off-by: David Teigland <teigland@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

| * | | [GFS2] Clean up inode number handlingSteven Whitehouse2007-07-09

The main difference is that instead of looking up the inodes using a struct gfs2_inum_host we now use just the no_addr member of this structure. The tests relating to no_formal_ino can then be done by the calling code. This has advantages in that we want to do different things in different code paths if the no_formal_ino doesn't match. In the NFS patch we want to return -ESTALE, but in the ->lookup() path, its a bug in the fs if the no_formal_ino doesn't match and thus we can withdraw in this case. In order to later fix bz #201012, we need to be able to look up an inode without knowing no_formal_ino, as the only information that is known to us is the on-disk location of the inode in question. This patch will also help us to fix bz #236099 at a later date by cleaning up a lot of the code in that area. There are no user visible changes as a result of this patch and there are no changes to the on-disk format either. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

So change the name to 'confirm', after debating this issue with Hugh Dickins a bit. A good return from ->confirm() means that the buffer is really there, and that the contents are good.
