Introduce scan capabilities to WEXT so that userspace can do intelligent things with scan behavior such as handling hidden SSIDs more gracefully. If the driver reports a specific scan capability, the driver must respect the options specified in the iw_scan_req structure when handling the SIOCSIWSCAN call, unless it's mode or state does not allow it to do so, in which case it must return an error. This version switches to Dave Kilroy's suggestion of claiming unused padding space for the scan_capa field. Signed-off-by:

This makes mac80211 include the low-level MAC timestamp in the radiotap header if the driver indicated (by a new RX flag) that the timestamp is valid. Signed-off-by:

The function follows48(), which is a special-case of dccp_delta_seqno(), is nowhere used in the DCCP code, thus removed by this patch. Signed-off-by:

This implements the changes to the nofeedback timer handling suggested in draft rfc3448bis00, section 4.4. In particular, these changes mean: * better handling of the lossless case (p == 0) * the timestamp for computing t_ld becomes obsolete * much more recent document (RFC 3448 is almost 5 years old) * concepts in rfc3448bis arose from a real, working implementation (cf. sec. 12) Signed-off-by:

* the NO_SENT state is only triggered in bidirectional mode, costing unnecessary processing. * the TERM (terminating) state is irrelevant. Signed-off-by:

This patch 1) concentrates previously scattered computation of p_inv into one function; 2) removes the `p' element of the CCID3 RX sock (it is redundant); 3) makes the tfrc_rx_info structure standalone, only used on demand. Signed-off-by:

The crc32c library used an identical table and algorithm as SCTP. Switch to using the library instead of carrying our own table. Using crypto layer proved to have too much overhead compared to using the library directly. Signed-off-by:

The seq_open_net patch changed the meaning of seq->private. Unfortunately it missed two spots in AF_PACKET, which still used the old way of dereferencing seq->private, thus causing weird and wonderful crashes when reading /proc/net/packet. Signed-off-by:

Change IPV4 specific macros LOOPBACK MULTICAST LOCAL_MCAST BADCLASS and ZERONET macros to inline functions ipv4_is_<type>(__be32 addr) Adds type safety and arguably some readability. Changes since last submission: Removed ipv4_addr_octets function Used hex constants Converted recently added rfc3330 macros Signed-off-by:

These are scattered over the code, but almost all the "critical" places already have the proper struct net at hand except for snmp proc showing function and routing rtnl handler. Signed-off-by:

They are all collected in the net/ipv4/devinet.c file and mostly use the IPV4_DEVCONF_DFLT macro. So I add the net parameter to it and patch users accordingly. Signed-off-by:

This is the core. Add all and default pointers on the netns_ipv4 and register a new pernet subsys to initialize them. Also add the ctl_table_header to register the net.ipv4.ip_forward ctl. I don't allocate additional memory for init_net, but use global devinets. Signed-off-by:

Some handers and strategies of devinet sysctl tables need to know the net to propagate the ctl change to all the net devices. I use the (currently unused) extra2 pointer on the tables to get it. Holding the reference on the struct net is not possible, because otherwise we'll get a net->ctl_table->net circular dependency. But since the ctl tables are unregistered during the net destruction, this is safe to get it w/o additional protection. Signed-off-by:

This one will need to set the IPV4_DEVCONF_ALL(PROXY_ARP), but there's no ways to get the net right in place, so we have to pull one from the inet_ioctl's struct sock. Signed-off-by:

Currently, this function is void, so failures in creating sysctls for new/renamed devices are not reported to anywhere. Fixing this is another complex (needed?) task, but this return value is needed during the namespaces creation to handle the case, when we failed to create "all" and "default" entries. Signed-off-by:

The ipv4 will store its parameters inside this structure. This one is empty now, but it will be eventually filled. Signed-off-by:

The _find calls calculate the hash value using the xfrm_state_hmask, without the xfrm_state_lock. But the value of this mask can change in the _resize call under the state_lock, so we risk to fail in finding the desired entry in hash. I think, that the hash value is better to calculate under the state lock. Signed-off-by:

Now that external users may increment the counters directly, we need to ensure that udp_stats_in6 is always available. Otherwise we'd either have to requrie the external users to be built as modules or ipv6 to be built-in. This isn't too bad because udp_stats_in6 is just a pair of pointers plus an EXPORT, e.g., just 40 (16 + 24) bytes on x86-64. Signed-off-by:

This introduces a CCMPS field for setting a CCID-specific upper bound on the application payload size, as is defined in RFC 4340, section 14. Only the TX CCID is considered in setting this limit, since the RX CCID generates comparatively small (DCCP-Ack) feedback packets. The CCMPS field includes network and transport layer header lengths. The only current CCMPS customer is CCID4 (via RFC 4828). A wrapper is used to allow querying the CCMPS even at times where the CCID modules may not have been fully negotiated yet. In dccp_sync_mss() the variable `mss_now' has been renamed into `cur_mps', to reflect that we are dealing with an MPS, but not an MSS. Since the DCCP code closely follows the TCP code, the identifiers `dccp_sync_mss' and `dccps_mss_cache' have been kept, as they have direct TCP counterparts. Signed-off-by:

The patch makes the registration messages of CCID 2/3 a bit more informative: instead of repeating the CCID number as currently done, "CCID: Registered CCID 2 (ccid2)" or "CCID: Registered CCID 3 (ccid3)", the descriptive names of the CCID's (from RFCs) are now used: "CCID: Registered CCID 2 (TCP-like)" and "CCID: Registered CCID 3 (TCP-Friendly Rate Control)". To allow spaces in the name, the slab name string has been changed to refer to the numeric CCID identifier, using the same format as before. Signed-off-by: -
