2011-12-06sock_diag: Move the sock_ code to net/core/Pavel Emelyanov1-1/+2
This patch moves the sock_ code from inet_diag.c to generic sock_diag.c file and provides necessary request_module-s calls and a pointer on inet_diag_compat dumping routine. Signed-off-by: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-11-28net: introduce skb_flow_dissect()Eric Dumazet1-1/+1
We use at least two flow dissectors in network stack, with known limitations and code duplication. Introduce skb_flow_dissect() to factorize this, highly inspired from existing dissector from __skb_get_rxhash() Note : We extensively use skb_header_pointer(), this permits us to not touch skb at all.

2011-11-22net: add network priority cgroup infrastructure (v4)Neil Horman1-0/+1
This patch adds in the infrastructure code to create the network priority cgroup. The cgroup, in addition to the standard processes file creates two control files: 1) prioidx - This is a read-only file that exports the index of this cgroup. This is a value that is both arbitrary and unique to a cgroup in this subsystem, and is used to index the per-device priority map 2) priomap - This is a writeable file. On read it reports a table of 2-tuples <name:priority> where name is the name of a network interface and priority is indicates the priority assigned to frames egresessing on the named interface and originating from a pid in this cgroup This cgroup allows for skb priority to be set prior to a root qdisc getting selected. This is benenficial for DCB enabled systems, in that it allows for any application to use dcb configured priorities so without application modification Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: John Fastabend <john.r.fastabend@intel.com> CC: Robert Love <robert.w.love@intel.com> CC: "David S.

2011-08-06net: Compute protocol sequence numbers and fragment IDs using MD5.David S. Miller1-1/+1
Computers have become a lot faster since we compromised on the partial MD4 hash which we use currently for performance reasons. MD5 is a much safer choice, and is inline with both RFC1948 and other ISS generators (OpenBSD, Solaris, etc.) Furthermore, only having 24-bits of the sequence number be truly unpredictable is a very serious limitation. So the periodic regeneration and 8-bit counter have been removed. We compute and use a full 32-bit sequence number. For ipv6, DCCP was found to use a 32-bit truncated initial sequence number (it needs 43-bits) and that is fixed here as well.

2010-07-18net: support time stamping in phy devices.Richard Cochran1-1/+1
This patch adds a new networking option to allow hardware time stamps from PHY devices. When enabled, likely candidates among incoming and outgoing network packets are offered to the PHY driver for possible time stamping. When accepted by the PHY driver, incoming packets are deferred for later delivery by the driver. The patch also adds phylib driver methods for the SIOCSHWTSTAMP ioctl and callbacks for transmit and receive time stamping. Drivers may optionally implement these functions.

2010-04-03net: convert multicast list to list_headJiri Pirko1-3/+2
Converts the list and the core manipulating with it to be the same as uc_list. +uses two functions for adding/removing mc address (normal and "global" variant) instead of a function parameter. +removes dev_mcast.c completely. +exposes netdev_hw_addr_list_* macros along with __hw_addr_* functions for manipulation with lists on a sandbox (used in bonding and 80211 drivers) Signed-off-by: Jiri Pirko <jpirko@redhat.com> Signed-off-by: David S.

2009-12-02skbuff: remove skb_dma_map/unmapAlexander Duyck1-1/+0
The two functions skb_dma_map/unmap are unsafe to use as they cause problems when packets are cloned and sent to multiple devices while a HW IOMMU is enabled. Due to this it is best to remove the code so it is not used by any other network driver maintainters.

2007-10-10[NET]: Fix running without sysfsEric W. Biederman1-1/+1
When sysfs support is compiled out the kernel still keeps and maintains the kobject tree. So it is not safe to skip our kobject reference counting or to avoid becoming members of the kobject tree. It is safe to not add the networking specific sysfs attributes. This patch removes the sysfs special cases from net/core/dev.c renames functions from netdev_sysfs_xxxx to netdev_kobject_xxxx and always compiles in net-sysfs.c net-sysfs.c is modified with a CONFIG_SYSFS guard around the parts that are actually sysfs specific.

2007-10-10[NET]: Basic network namespace infrastructure.Eric W. Biederman1-1/+1
This is the basic infrastructure needed to support network namespaces. This infrastructure is: - Registration functions to support initializing per network namespace data when a network namespaces is created or destroyed. - struct net. The network namespace data structure. This structure will grow as variables are made per network namespace but this is the minimal starting point. - Functions to grab a reference to the network namespace. I provide both get/put functions that keep a network namespace from being freed. And hold/release functions serve as weak references and will warn if their count is not zero when the data structure is freed. Useful for dealing with more complicated data structures like the ipv4 route cache. - A list of all of the network namespaces so we can iterate over them. - A slab for the network namespace data structure allowing leaks to be spotted.

2005-06-18[NET] Generalise tcp_listen_optArnaldo Carvalho de Melo1-1/+2
This chunks out the accept_queue and tcp_listen_opt code and moves them to net/core/request_sock.c and include/net/request_sock.h, to make it useful for other transport protocols, DCCP being the first one to use it. Next patches will rename tcp_listen_opt to accept_sock and remove the inline tcp functions that just call a reqsk_queue_ function.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+17
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
