* [Syncookies]: Add support for TCP options via timestamps.Florian Westphal2008-04-10
| | | | | | | | | | | | | | | | | | | | | | | | | Allow the use of SACK and window scaling when syncookies are used and the client supports tcp timestamps. Options are encoded into the timestamp sent in the syn-ack and restored from the timestamp echo when the ack is received. Based on earlier work by Glenn Griffin. This patch avoids increasing the size of structs by encoding TCP options into the least significant bits of the timestamp and by not using any 'timestamp offset'. The downside is that the timestamp sent in the packet after the synack will increase by several seconds. changes since v1: don't duplicate timestamp echo decoding function, put it into ipv4/syncookie.c and have ipv6/syncookies.c use it.

* IPV4: fib_trie use vmalloc for large tnodesStephen Hemminger2008-04-10
| | | | | | | | | | | | | | | Use vmalloc rather than alloc_pages to avoid wasting memory. The problem is that tnode structure has a power of 2 sized array, plus a header. So the current code wastes almost half the memory allocated because it always needs the next bigger size to hold that small header. This is similar to an earlier patch by Eric, but instead of a list and lock, I used a workqueue to handle the fact that vfree can't be done in interrupt context.

* [SKFILTER]: Add SKF_ADF_NLATTR instructionPatrick McHardy2008-04-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SKF_ADF_NLATTR searches for a netlink attribute, which avoids manually parsing and walking attributes. It takes the offset at which to start searching in the 'A' register and the attribute type in the 'X' register and returns the offset in the 'A' register. When the attribute is not found it returns zero. A top-level attribute can be located using a filter like this (example for nfnetlink, using struct nfgenmsg): ... { /* A = offset of first attribute */ .code = BPF_LD | BPF_IMM, .k = sizeof(struct nlmsghdr) + sizeof(struct nfgenmsg) }, { /* X = CTA_PROTOINFO */ .code = BPF_LDX | BPF_IMM, .k = CTA_PROTOINFO, }, { /* A = netlink attribute offset */ .code = BPF_LD | BPF_B | BPF_ABS, .k = SKF_AD_OFF + SKF_AD_NLATTR }, { /* Exit if not found */ .code = BPF_JMP | BPF_JEQ | BPF_K, .k = 0, .jt = <error> }, ... A nested attribute below the CTA_PROTOINFO attribute would then be parsed like this: ... { /* A += sizeof(struct nlattr) */ .code = BPF_ALU | BPF_ADD | BPF_K, .k = sizeof(struct nlattr), }, { /* X = CTA_PROTOINFO_TCP */ .code = BPF_LDX | BPF_IMM, .k = CTA_PROTOINFO_TCP, }, { /* A = netlink attribute offset */ .code = BPF_LD | BPF_B | BPF_ABS, .k = SKF_AD_OFF + SKF_AD_NLATTR }, ... The data of an attribute can be loaded into 'A' like this: ... { /* X = A (attribute offset) */ .code = BPF_MISC | BPF_TAX, }, { /* A = skb->data[X + k] */ .code = BPF_LD | BPF_B | BPF_IND, .k = sizeof(struct nlattr), }, ...

* mac80211: fix key vs. sta locking problemsJohannes Berg2008-04-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Up to now, key manipulation is supposed to run under RTNL to avoid concurrent manipulations and also allow the set_key() hardware callback to sleep. This is not feasible because STA structs are rcu-protected and thus a lot of operations there cannot take the RTNL. Also, key references are rcu-protected so we cannot do things atomically. This patch changes key locking completely: * key operations are now atomic * hardware crypto offload is enabled and disabled from a workqueue, due to that key freeing is also delayed * debugfs code is also run from a workqueue * keys reference STAs (and vice versa!) so during STA unlink the STAs key reference is removed but not the keys STA reference, to avoid races key todo work is run before STA destruction. * fewer STA operations now need the RTNL which was required due to key operations This fixes the locking problems lockdep pointed out and also makes things more light-weight because the rtnl isn't required as much. Note that the key todo lock/key mutex are global locks, this is not required, of course, they could be per-hardware instead.

* mac80211: make debugfs files root-onlyJohannes Berg2008-04-08
| | | | | | | | | | | | | | | Unfortunately, debugfs can be made to access invalid memory by open()ing a file and then waiting until the corresponding debugfs file has been removed (and, probably, the underlying object.)

* mac80211: fix possible sta-debugfs work lockupJohannes Berg2008-04-08

This patch fixes it by moving this work to the common kernel workqueue (using schedule_work) and canceling it as appropriate. It also fixes a related problem: When a STA is pinned by the debugfs adding work and sta_info_flush() runs concurrently it is not guaranteed that all STAs are removed from the driver before the corresponding interface is removed which may lead to bugs.
