tproxy: fix hash locking issue when using port redirection in __inet_inherit_port()

2010-10-21T11:06:43Z

When __inet_inherit_port() is called on a tproxy connection the wrong locks are held for the inet_bind_bucket it is added to. __inet_inherit_port() made an implicit assumption that the listener's port number (and thus its bind bucket). Unfortunately, if you're using the TPROXY target to redirect skbs to a transparent proxy that assumption is not true anymore and things break. This patch adds code to __inet_inherit_port() so that it can handle this case by looking up or creating a new bind bucket for the child socket and updates callers of __inet_inherit_port() to gracefully handle __inet_inherit_port() failing. Reported by and original patch from Stephen Buck . See http://marc.info/?t=128169268200001&r=1&w=2 for the original discussion. Signed-off-by: KOVACS Krisztian Signed-off-by: Patrick McHardy

tcp: Fix a connect() race with timewait sockets

2009-12-09T04:17:51Z

First patch changes __inet_hash_nolisten() and __inet6_hash() to get a timewait parameter to be able to unhash it from ehash at same time the new socket is inserted in hash. This makes sure timewait socket wont be found by a concurrent writer in __inet_check_established() Reported-by: kapil dakhane Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

inet: fix inet_bind_bucket_for_each

2009-11-14T04:46:56Z

The first "node" is supposed to be the cursor used in the for_each. The second "node" is ment literally and should not be macro expanded: it's the name of the hlist_node field from the inet_bind_bucket. This currently works because when inet_bind_bucket_for_each is called it's argument is still "node". Signed-off-by: Lucian Adrian Grijincu Signed-off-by: David S. Miller

inet: rename some inet_sock fields

2009-10-19T01:52:53Z

In order to have better cache layouts of struct sock (separate zones for rx/tx paths), we need this preliminary patch. Goal is to transfert fields used at lookup time in the first read-mostly cache line (inside struct sock_common) and move sk_refcnt to a separate cache line (only written by rx path) This patch adds inet_ prefix to daddr, rcv_saddr, dport, num, saddr, sport and id fields. This allows a future patch to define these fields as macros, like sk_refcnt, without name clashes. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

tcp: replace ehash_size by ehash_mask

2009-10-13T10:44:02Z

Storing the mask (size - 1) instead of the size allows fast path to be a bit faster. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

net: skb->dst accessors

2009-06-03T09:51:04Z

Define three accessors to get/set dst attached to a skb struct dst_entry *skb_dst(const struct sk_buff *skb) void skb_dst_set(struct sk_buff *skb, struct dst_entry *dst) void skb_dst_drop(struct sk_buff *skb) This one should replace occurrences of : dst_release(skb->dst) skb->dst = NULL; Delete skb->dst field Signed-off-by: Eric Dumazet Signed-off-by: David S.

net: wrong test in inet_ehash_locks_alloc()

2009-01-28T01:45:10Z

In commit 9db66bdcc83749affe61c61eb8ff3cf08f42afec (net: convert TCP/DCCP ehash rwlocks to spinlocks), I forgot to change one occurrence of rwlock_t to spinlock_t I believe sizeof(raw_spinlock_t) might be > 0 on !CONFIG_SMP if CONFIG_DEBUG_SPINLOCK while sizeof(raw_rwlock_t) should be 0 in this case. Fortunatly, CONFIG_DEBUG_SPINLOCK adds fields to both spinlock_t and rwlock_t, but at this might change in the future (being able to debug spinlocks but not rwlocks for example), better to be safe.
