* net: convert multicast list to list_headJiri Pirko2010-04-032-4/+4
| | | | | | | | | | | | | 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.

* net: snmp mib cleanupEric Dumazet2010-03-221-2/+2
| | | | | | | | | | | | There is no point to align or pad mibs to cache lines, they are per cpu allocated with a 8 bytes alignment anyway. This wastes space for no gain. This patch removes __SNMP_MIB_ALIGN__ Since SNMP mibs contain "unsigned long" fields only, we can relax the allocation alignment from "unsigned long long" to "unsigned long" Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

* tcp: Add SNMP counter for DEFER_ACCEPTEric Dumazet2010-03-222-0/+2
| | | | | | | | | | | | | | | | | | | Its currently hard to diagnose when ACK frames are dropped because an application set TCP_DEFER_ACCEPT on its listening socket. See http://bugzilla.kernel.org/show_bug.cgi?id=15507 This patch adds a SNMP value, named TCPDeferAcceptDrop netstat -s | grep TCPDeferAcceptDrop TCPDeferAcceptDrop: 0 This counter is incremented every time we drop a pure ACK frame received by a socket in SYN_RECV state because its SYNACK retrans count is lower than defer_accept value.

| * NET_DMA: free skbs periodicallySteven J. Magnani2010-03-201-20/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Under NET_DMA, data transfer can grind to a halt when userland issues a large read on a socket with a high RCVLOWAT (i.e., 512 KB for both). This appears to be because the NET_DMA design queues up lots of memcpy operations, but doesn't issue or wait for them (and thus free the associated skbs) until it is time for tcp_recvmesg() to return. The socket hangs when its TCP window goes to zero before enough data is available to satisfy the read. Periodically issue asynchronous memcpy operations, and free skbs for ones that have completed, to prevent sockets from going into zero-window mode. Signed-off-by: Steven J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mfc_parent of cache entries is used to index into the vif_table and is initialised from mfcctl->mfcc_parent. This can take values of to 2^16-1, while the vif_table has only MAXVIFS (32) entries. The same problem affects ip6mr. Refuse invalid values to fix a potential out-of-bounds access. Unlike the other validity checks, this is checked in ipmr_mfc_add() instead of the setsockopt handler since its unused in the delete path and might be uninitialized.

| * ipv4: check rt_genid in dst_checkTimo Teräs2010-03-201-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Xfrm_dst keeps a reference to ipv4 rtable entries on each cached bundle. The only way to renew xfrm_dst when the underlying route has changed, is to implement dst_check for this. This is what ipv6 side does too. The problems started after 87c1e12b5eeb7b30b4b41291bef8e0b41fc3dde9 ("ipsec: Fix bogus bundle flowi") which fixed a bug causing xfrm_dst to not get reused, until that all lookups always generated new xfrm_dst with new route reference and path mtu worked. But after the fix, the old routes started to get reused even after they were expired causing pmtu to break (well it would occationally work if the rtable gc had run recently and marked the route obsolete causing dst_check to get called).

| * ipconfig: Handle devices which take some time to come up.David S. Miller2010-03-121-10/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some network devices, particularly USB ones, take several seconds to fully init and appear in the device list. If the user turned ipconfig on, they are using it for NFS root or some other early booting purpose. So it makes no sense to just flat out fail immediately if the device isn't found. It also doesn't make sense to just jack up the initial wait to something crazy like 10 seconds. Instead, poll immediately, and then periodically once a second, waiting for a usable device to appear. Fail after 12 seconds. Signed-off-by: David S. Miller <davem@davemloft.net> Tested-by: Christian Pellegrin <chripell@fsfe.org>

One of the assumption of original patch, was that entries where kept sorted in a given way. This assumption is known to be wrong (commit 1ddbcb005c395518 gave an explanation of this and corrected a leak) and expensive to respect. Paweł Staszewski reported to me one of his machine got its routing cache disabled after few messages like : [ 2677.850065] Route hash chain too long! [ 2677.850080] Adjust your secret_interval! [82839.662993] Route hash chain too long! [82839.662996] Adjust your secret_interval! [155843.731650] Route hash chain too long! [155843.731664] Adjust your secret_interval! [155843.811881] Route hash chain too long! [155843.811891] Adjust your secret_interval! [155843.858209] vlan0811: 5 rebuilds is over limit, route caching disabled [155843.858212] Route hash chain too long! [155843.858213] Adjust your secret_interval! This is because rt_intern_hash() might be fooled when computing a chain length, because multiple entries with same keys can differ because of TOS (or mark/oif) bits. In the rare case the fast algorithm see a too long chain, and before taking expensive path, we call a helper function in order to not count duplicates of same routes, that only differ with tos/mark/oif bits. This helper works with data already in cpu cache and is not be very expensive, despite its O(N^2) implementation. Paweł Staszewski sucessfully tested this patch on his loaded router.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ipgre_header() can be called with zero daddr when the gre device is configured as multipoint tunnel and still has the NOARP flag set (which is typically cleared by the userspace arp daemon). If the NOARP packets are not dropped, ipgre_tunnel_xmit() will take rt->rt_gateway (= NBMA IP) and use that for route look up (and may lead to bogus xfrm acquires). The multicast address check is removed as sending to multicast group should be ok. In fact, if gre device has a multicast address as destination ipgre_header is always called with multicast address.

Instead of getting from the caller, it was instead set to the flow in the route object, which is totally different. The end result is that the bundles we created never match, and we instead end up with an ever growing bundle list. Thanks to Jamal for find this problem.

* | | percpu: add __percpu sparse annotations to netTejun Heo2010-02-174-47/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add __percpu sparse annotations to net. These annotations are to make sparse consider percpu variables to be in a different address space and warn if accessed without going through percpu accessors. This patch doesn't affect normal builds. The macro and type tricks around snmp stats make things a bit interesting. DEFINE/DECLARE_SNMP_STAT() macros mark the target field as __percpu and SNMP_UPD_PO_STATS() macro is updated accordingly. All snmp_mib_*() users which used to cast the argument to (void **) are updated to cast it to (void __percpu **). Signed-off-by: Tejun Heo <tj@kernel.org> Acked-by: David S.

| * | ipcomp: Avoid duplicate calls to ipcomp_destroyHerbert Xu2010-02-161-5/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When ipcomp_tunnel_attach fails we will call ipcomp_destroy twice. This may lead to double-frees on certain structures. As there is no reason to explicitly call ipcomp_destroy, this patch removes it from ipcomp*.c and lets the standard xfrm_state destruction take place. This is based on the discovery and patch by Alexey Dobriyan. Tested-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.
