Thanks dave, herbert, gerrit, andi and other people for your discussion about this problem. UdpInDatagrams can be confusing because it counts packets that might be dropped later. Move UdpInDatagrams into recvmsg() as allowed by the RFC. Signed-off-by:

To get there, highest_sack must have advanced. When it advances, a new skb is SACKed, which already sets that FLAG. Besides, the original purpose of it has puzzled me, never understood why LOST bit setting of retransmitted skb is marked with FLAG_DATA_SACKED. Signed-off-by:

Usually those skbs will have L set, not counting them as lost retransmissions is misleading. Signed-off-by:

This looks very much like the patch for ipv4's devinet. This is also intended to help us with the net namespaces and saves the ipv6.ko size by ~320 bytes. The difference from the first version is just the patch offsets, that changed due to changes in the patch #2. Signed-off-by:

Currently this call is (ab)used similar to devinet one - it registers sysctls for devices and for the "default" confs, while the "all" sysctls are registered separately. But unlike its devinet brother, the passed inet6_device is needed. The fix is to make a __addrconf_sysctl_register(), which registers sysctls for all "devices" we need, including "default" and "all" :) The original addrconf_sysctl_register() calls the introduced function, passing the inet6_device, device name and ifindex (to be used as procname and ctl_name) into it. Thanks to Herbert again for pointing out, that we can shrink the argument list to 1 :) Signed-off-by:

This looks very much like the patch for neighbors. The path is also located on the stack and is prepared inside the function. This time, the call to the registering function is guarded with the RTNL lock, but I decided to keep it on the stack not to litter the devinet.c file with unneeded names and to make it look similar to the neighbors code. This is also intended to help us with the net namespaces and saves the vmlinux size as well - this time by more than 670 bytes. The difference from the first version is just the patch offsets, that changed due to changes in the patch #2. Signed-off-by:

Besides, the inet_device is passed to this function, but it is not needed there at all - just the device name and ifindex are required. Thanks to Herbert, who noticed, that this call doesn't even require the devconf pointer (the last argument) - all we need we can take from the in_device itself. The fix is to make a __devinet_sysctl_register(), which registers sysctls for all "devices" we need, including "default" and "all" :) The original devinet_sysctl_register() works with struct net_device, not the inet_device, and calls the introduced function, passing the device name and ifindex (to be used as procname and ctl_name) into it.

These bits were dead code before "mac80211: Remove local->scan_flags" (commit 6681dd3fd0e4d36a4547415853e83411baa7b705) and probably should have been removed as part of that commit. Signed-off-by:

This patch adds the capability to identify and answer an add block ACK request. As this series of patches only adds HT handling with no aggregations, (A-MPDU aggregations acceptance is not obligatory according to 802.11n draft) we are currently sending back a refusal upon this request.

Interface iteration in mac80211 can be done without holding any locks because I converted it to RCU. Initially, I thought this wouldn't be needed for ieee80211_iterate_active_interfaces but it's turning out that multi-BSS AP support can be much simpler in a driver if ieee80211_iterate_active_interfaces can be called without holding locks. This converts it to use RCU, it adds a requirement that the callback it invokes cannot sleep. Signed-off-by:

This patch restructures the Rx handlers chain by incorporating previously handlers ieee80211_rx_h_802_1x_pae and ieee80211_rx_h_drop_unencrypted into ieee80211_rx_h_data, already in 802.3 form. this scheme follows more precisely after the IEEE802.11 data plane archituecture, and will prevent code duplication to IEEE8021.11n A-MSDU handler. added function: - ieee80211_data_to_8023: transfering 802.11 data frames to 802.3 frame - ieee80211_deliver_skb: delivering the 802.3 frames to upper stack eliminated handlers: - ieee80211_rx_h_drop_unencrypted: now function ieee80211_drop_unencrypted - ieee80211_rx_h_802_1x_pae: now function ieee80211_802_1x_pae changed handlers: - ieee80211_rx_h_data: now contains calls to four above function Signed-off-by:

The scan code in mac80211 makes the software scan assumption in various places. For example, we stop the Tx queue during a software scan so that all the Tx packets will be queued by the stack. We also drop frames not related to scan in the software scan process. But these are not true for hardware scan. Some wireless hardwares (for example iwl3945/4965) has the ability to perform the whole scan process by hardware and/or firmware. The hardware scan is relative powerful in that it tries to maintain normal network traffic while doing a scan in the background. Some drivers (i.e iwlwifi) do provide a way to tune the hardware scan parameters (for example if the STA is associated, what's the max time could the STA leave from the associated channel, how long the scans get suspended after returning to the service channel, etc). But basically this is transparent to the stack. mac80211 should not stop Tx queues or drop Rx packets during a hardware scan. This patch resolves the above problem by spliting the current scan indicator local->sta_scanning into local->sta_sw_scanning and local->sta_hw_scanning. It then changes the scan related code to be aware of hardware scan or software scan in various places. With this patch, iwlwifi performs much better in the scan-while-associated condition and disable_hw_scan=1 should never be required.

I moved the call to kmalloc() from the *t declaration into the code (this is confusing when a variable is initialized with the result of some call) and removed unneeded comment near the error path. Just like I did with the neigh ctl-s. Besides, I fixed the goto's and the labels - they were indented with spaces :( Signed-off-by:

Pavel Emelyanov authored
The appropriate path is prepared right inside this function. It is prepared similar to how the ctl tables were. Since the path is modified, it is put on the stack, to avoid possible races with multiple calls to neigh_sysctl_register() : it is called by protocols and I didn't find any protection in this case. Did I overlooked the rtnl lock?. The stack growth of the neigh_sysctl_register() is 40 bytes. I believe this is OK, since this is not that much and this function is not called with the deep stack (device/protocols register). The device's name is stored on the template to free it later. This will help with the net namespaces, as each namespace should have its own set of these ctls. Besides, this saves ~350 bytes from the neigh template :) Signed-off-by:

This mainly removes the err variable, as this call always return the same error code (-ENOBUFS). Besides, I moved the call to kmalloc() from the *t declaration into the code (this is confusing when a variable is initialized with the result of some call) and removed unneeded comment near the error path.

This is the core. * add the ctl_table_header on the struct net; * make the unix_sysctl_register and _unregister clone the table; * moves calls to them into per-net init and exit callbacks; * move the .data pointer in the proper place. Signed-off-by:

This will make all the sub-namespaces always use the default value (10) and leave the tuning via sysctl to the init namespace only. Per-namespace tuning is coming. Signed-off-by:

Currently the netmask/prefix-length of an IPsec SPD entry is not included in any of the SPD related audit messages. This can cause a problem when the audit log is examined as the netmask/prefix-length is vital in determining what network traffic is affected by a particular SPD entry. This patch fixes this problem by adding two additional fields, "src_prefixlen" and "dst_prefixlen", to the SPD audit messages to indicate the source and destination netmasks. These new fields are only included in the audit message when the netmask/prefix-length is less than the address length, i.e. the SPD entry applies to a network address and not a host address. Example audit message: type=UNKNOWN[1415] msg=audit(1196105849.752:25): auid=0 \ subj=root:system_r:unconfined_t:s0-s0:c0.c1023 op=SPD-add res=1 \ src=192.168.0.0 src_prefixlen=24 dst=192.168.1.0 dst_prefixlen=24 In addition, this patch also fixes a few other things in the xfrm_audit_common_policyinfo() function. The IPv4 string formatting was converted to use the standard NIPQUAD_FMT constant, the memcpy() was removed from the IPv6 code path and replaced with a typecast (the memcpy() was acting as a slow, implicit typecast anyway), and two local variables were created to make referencing the XFRM security context and selector information cleaner.
