The txrates substructure has been extended to provide different fields for different types of packets (management/data, unicast/multicast). These fields are updated on association to values compatible with the access point we are associating to. Drivers can then use the new ieee80211softmac_suggest_txrate() function call when deciding which rate to transmit each frame at. This is immensely useful for ZD1211, and bcm can use it too. The user can still specify a rate through iwconfig, which is matched for all transmissions (assuming the rate they have specified is in the rate set required by the AP). At a later date, we can incorporate automatic rate management into the ieee80211softmac_recalc_txrates() function. This patch also removes the mcast_fallback field. Sam Leffler pointed out that this field is meaningless, because no driver will ever be retransmitting mcast frames (they are not acked).

The complication here is that we need to encrypt a management frame during the authentication process. I don't think there are any other scenarios where this would have to happen. To get around this without causing too many headaches, we decided to just use software encryption for this frame. The softmac config option now selects IEEE80211_CRYPT_WEP so that we can ensure this available. This also involved a modification to some otherwise unused ieee80211 API.

It was broadcasting beacons but wouldn't respond to any authentication requests. I noticed that softmac wasn't playing nice with this, as I couldn't make it try to connect to other networks after it had timed out authenticating to my ill router. To resolve this, I modified the softmac event/notify API to pass the event code to the callback, so that callbacks being notified from IEEE80211SOFTMAC_EVENT_ANY masks can make some judgement. In this case, the ieee80211softmac_assoc callback needs to make a decision based upon whether the association passed or failed.

This can be a scalability issue for some workloads, especially for devices driven by the ipath driver, which needs to call into the kernel even for datapath operations. Fix this by adding reference counts to the userspace objects, and then converting ib_uverbs_idr_mutex into a spinlock that only protects the idrs long enough to take a reference on the object being looked up. Because remove operations may fail, we have to do a slightly funky two-step deletion, which is described in the comments at the top of uverbs_cmd.c. This also still leaves ib_uverbs_idr_lock as a single lock that is possibly subject to contention. However, the lock hold time will only be a single idr operation, so multiple threads should still be able to make progress, even if ib_uverbs_idr_lock is being ping-ponged. Surprisingly, these changes even shrink the object code: add/remove: 23/5 grow/shrink: 4/21 up/down: 633/-693 (-60) Signed-off-by: Roland Dreier --- include/rdma/ib_verbs.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'include') diff --git a/include/rdma/ib_verbs.h b/include/rdma/ib_verbs.h index 7ced208edacf..ee1f3a355666 100644 --- a/include/rdma/ib_verbs.h +++ b/include/rdma/ib_verbs.h @@ -697,8 +697,12 @@ struct ib_ucontext { struct ib_uobject { u64 user_handle; /* handle given to us by userspace */ struct ib_ucontext *context; /* associated user context */ + void *object; /* containing object */ struct list_head list; /* link to context's list */ u32 id; /* index into kernel idr */ + struct kref ref; + struct rw_semaphore mutex; /* protects .live */ + int live; }; struct ib_umem { -- cgit v1.2.2 From c13c8260da3155f2cefb63b0d1b7dcdcb405c644 Mon Sep 17 00:00:00 2001 From: Chris Leech Date: Tue, 23 May 2006 17:18:44 -0700 Subject: [I/OAT]: DMA memcpy subsystem Provides an API for offloading memory copies to DMA devices Signed-off-by: Chris Leech Signed-off-by: David S.

This is based on the observation that the write locks are only held by module insertion/removal which are very rare events so there is no need to further differentiate between the insertion of modules like ipv6 versus esp6. The removal of the read locks in xfrm4_policy.c/xfrm6_policy.c might look suspicious at first. However, after you realise that nobody ever takes the corresponding write lock you'll feel better :) As far as I can gather it's an attempt to guard against the removal of the corresponding modules. Since neither module can be unloaded at all we can leave it to whoever fixes up IPv6 unloading :) Signed-off-by: Herbert Xu Signed-off-by: David S.

In the previous patch, no authorization (besides the check for write permissions to SAD and SPD) is required to delete IPsec policies and security assocations with security contexts. Thus a user authorized to change SAD and SPD can bypass the IPsec policy authorization by simply deleteing policies with security contexts. To fix this security hole, an additional authorization check is added for removing security policies and security associations with security contexts. Note that if no security context is supplied on add or present on policy to be deleted, the SELinux module allows the change unconditionally. The hook is called on deletion when no context is present, which we may want to change. At present, I left it up to the module. LSM changes: The patch adds two new LSM hooks: xfrm_policy_delete and xfrm_state_delete. The new hooks are necessary to authorize deletion of IPsec policies that have security contexts. The existing hooks xfrm_policy_free and xfrm_state_free lack the context to do the authorization, so I decided to split authorization of deletion and memory management of security data, as is typical in the LSM interface. Use: The new delete hooks are checked when xfrm_policy or xfrm_state are deleted by either the xfrm_user interface (xfrm_get_policy, xfrm_del_sa) or the pfkey interface (pfkey_spddelete, pfkey_delete). SELinux changes: The new policy_delete and state_delete functions are added. Signed-off-by: Catherine Zhang Signed-off-by: Trent Jaeger Acked-by: James Morris Signed-off-by: David S.

This is similar to the CONNMARK target, but is more limited in scope in that it only allows copying of security marks to and from packets, as this is all it needs to do. A typical scenario would be to apply a security mark to a 'new' packet with SECMARK, then copy that to its conntrack via CONNMARK, and then restore the security mark from the connection to established and related packets on that connection.

They do so without setting xmit_lock_owner. This is fine as long as netpoll is not in use. With netpoll it is possible for deadlocks to occur if xmit_lock_owner isn't set. This is because if a printk occurs while xmit_lock is held and xmit_lock_owner is not set can cause netpoll to attempt to take xmit_lock recursively. While it is possible to resolve this by getting netpoll to use trylock, it is suboptimal because netpoll's sole objective is to maximise the chance of getting the printk out on the wire. So delaying or dropping the message is to be avoided as much as possible. So the only alternative is to always set xmit_lock_owner. The following patch does this by introducing the netif_tx_lock family of functions that take care of setting/unsetting xmit_lock_owner. I renamed xmit_lock to _xmit_lock to indicate that it should not be used directly. I didn't provide irq versions of the netif_tx_lock functions since xmit_lock is meant to be a BH-disabling lock. This is pretty much a straight text substitution except for a small bug fix in winbond. It currently uses netif_stop_queue/spin_unlock_wait to stop transmission. This is unsafe as an IRQ can potentially wake up the queue. So it is safer to use netif_tx_disable. The hamradio bits used spin_lock_irq but it is unnecessary as xmit_lock must never be taken in an IRQ handler. Signed-off-by: Herbert Xu Signed-off-by: David S.

So we can replace __skb_linearize with __pskb_pull_tail which does the same thing but is more general. Also, most users of skb_linearize end up testing whether the skb is linear or not so it helps to make skb_linearize do just that. Some callers of skb_linearize also use it to copy cloned data, so it's useful to have a new function skb_linearize_cow to copy the data if it's either non-linear or cloned. Last but not least, I've removed the gfp argument since nobody uses it anymore. If it's ever needed we can easily add it back.

"=&r" constraint should be used for oldval. 2. Instead of "r" (uaddr), "=R" (*uaddr) for output and "R" (*uaddr) for input should be used. 3. "memory" should be added to the clobber list.

Most architecture definitions of kern_addr_valid() just define it as 1; the Alpha and CONFIG_DISCONTIGMEM on i386 and MIPS even as 0; the 0-definition will result in kmem_ptr_validate always failing which in turn will cause d_validate to always fail. d_validate's only two users are smbfs and ncpfs, so the 0 definition ended breaking those ...
