* rtl8187: Fix lockups due to concurrent access to config routineLarry Finger2008-08-012-1/+18
| | | | | | | | | | | | | | | | | | | Some users of the RTL8187B have experienced difficulties since commit 49292d56352a6ab90d04c3448dd8b6106dfef2d6 that introduced the power management wext hooks. This difficulty has not made much sense until it was realized that it was possible for mac80211 to make a call to the config routine while that routine was already being executed. On this device, it is necessary to loopback the TX when changing channels. Unless this is properly restored, the device will lockup. A mutex now protects the device state, and the private data in several places. The problem was found by Herton Ronaldo Krzesinski <herton@mandriva.com.br>, who also suggested this type of fix.

* rt2500pci: restoring missing linePeter Chubb2008-08-011-0/+1
| | | | | | | | | | | | | | | | | | | | In kernel version 2.6.26-rc9 my wireless LAN card worked; but in the released 2.6.26, my RaLink rt2500 card wouldn't associate. Git-bisect led me to this patch: 61486e0f68d1f8966c09b734566a187d42d65c54 rt2x00: Remove ieee80211_tx_control argument from write_tx_desc() I believe that there is a problem with that patch --- it (inadvertantly) removes an extra line of code, that used to set the DATABYTE_COUNT field. This patch reinstates that line, and with it my card works again. Signed-off-by: Peter Chubb <peterc@gelato.unsw.edu.au> Acked-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

| | | | | | | | | | | | | | | | Every time a new input device that is capable of one of the rfkill EV_SW events (currently only SW_RFKILL_ALL) is connected to rfkill-input, we must check the states of the input EV_SW switches and take action.

| | | | | | | | | | | | | | I noticed, looking at tcpdumps, that timewait ACKs were getting sent with an incorrect MD5 signature when signatures were enabled. I broke this in 49a72dfb8814c2d65bd9f8c9c6daf6395a1ec58d ("tcp: Fix MD5 signatures for non-linear skbs").

* ipv6: Fix ip6_xmit to send fragments if ipfragok is trueWei Yongjun2008-07-311-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | SCTP used ip6_xmit() to send fragments after received ICMP packet too big message. But while send packet used ip6_xmit, the skb->local_df is not initialized. So when skb if enter ip6_fragment(), the following code will discard the skb. ip6_fragment(...) { if (!skb->local_df) { ... return -EMSGSIZE; } ... } SCTP do the following step: 1. send packet ip6_xmit(skb, ipfragok=0) 2. received ICMP packet too big message 3. if PMTUD_ENABLE: ip6_xmit(skb, ipfragok=1) This patch fixed the problem by set local_df if ipfragok is true.

* ipvs: Move userspace definitions to include/linux/ip_vs.hJulius Volz2008-07-313-245/+254
| | | | | | | | | | | | | | | | | | | | Current versions of ipvsadm include "/usr/src/linux/include/net/ip_vs.h" directly. This file also contains kernel-only definitions. Normally, public definitions should live in include/linux, so this patch moves the definitions shared with userspace to a new file, "include/linux/ip_vs.h". This also removes the unused NFC_IPVS_PROPERTY bitmask, which was once used to point into skb->nfcache. To make old ipvsadms still compile with this, the old header file includes the new one.

* netdev: Fix lockdep warnings in multiqueue configurations.David S. Miller2008-07-317-44/+78
| | | | | | | | | | | | | | When support for multiple TX queues were added, the netif_tx_lock() routines we converted to iterate over all TX queues and grab each queue's spinlock. This causes heartburn for lockdep and it's not a healthy thing to do with lots of TX queues anyways. So modify this to use a top-level lock and a "frozen" state for the individual TX queues.

* netfilter: xt_hashlimit: fix race between htable_destroy and htable_gcPavel Emelyanov2008-07-311-3/+1
| | | | | | | | | | | | | | | | | Deleting a timer with del_timer doesn't guarantee, that the timer function is not running at the moment of deletion. Thus in the xt_hashlimit case we can get into a ticklish situation when the htable_gc rearms the timer back and we'll actually delete an entry with a pending timer. Fix it with using del_timer_sync(). AFAIK del_timer_sync checks for the timer to be pending by itself, so I remove the check.

* netfilter: ipt_recent: fix race between recent_mt_destroy and proc manipulationsPavel Emelyanov2008-07-311-1/+1
| | | | | | | | | | | | | | | | | | | | The thing is that recent_mt_destroy first flushes the entries from table with the recent_table_flush and only *after* this removes the proc file, corresponding to that table. Thus, if we manage to write to this file the '+XXX' command we will leak some entries. If we manage to write there a 'clean' command we'll race in two recent_table_flush flows, since the recent_mt_destroy calls this outside the recent_lock. The proper solution as I see it is to remove the proc file first and then go on with flushing the table. This flushing becomes safe w/o the lock, since the table is already inaccessible from the outside.

* bridge: send correct MTU value in PMTU (revised)Simon Wunderlich2008-07-304-30/+51
| | | | | | | | | | | | | | | | | | | | | When bridging interfaces with different MTUs, the bridge correctly chooses the minimum of the MTUs of the physical devices as the bridges MTU. But when a frame is passed which fits through the incoming, but not through the outgoing interface, a "Fragmentation Needed" packet is generated. However, the propagated MTU is hardcoded to 1500, which is wrong in this situation. The sender will repeat the packet again with the same frame size, and the same problem will occur again. Instead of sending 1500, the (correct) MTU value of the bridge is now sent via PMTU. To achieve this, the corresponding rtable structure is stored in its net_bridge structure. Modified to get rid of fake_net_device as well. Signed-off-by: Simon Wunderlich <siwu@hrz.tu-chemnitz.de> Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mutex is released on a successful return, so it would seem that it should be released on an error return as well. The semantic patch finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression l; @@ mutex_lock(l); ... when != mutex_unlock(l) when any when strict ( if (...) { ... when != mutex_unlock(l) + mutex_unlock(l); return ...; } | mutex_unlock(l); ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
