2006-05-19[SCTP]: Allow linger to abort 1-N style sockets.Vladislav Yasevich
Enable SO_LINGER functionality for 1-N style sockets. The socket API draft will be clarfied to allow for this functionality. The linger settings will apply to all associations on a given socket.

2006-05-19[SCTP]: Validate the parameter length in HB-ACK chunk.Vladislav Yasevich
If SCTP receives a badly formatted HB-ACK chunk, it is possible that we may access invalid memory and potentially have a buffer overflow. We should really make sure that the chunk format is what we expect, before attempting to touch the data.

2006-05-19[SCTP]: A better solution to fix the race between sctp_peeloff() andVladislav Yasevich
sctp_rcv(). The goal is to hold the ref on the association/endpoint throughout the state-machine process. We accomplish like this: /* ref on the assoc/ep is taken during lookup */ if owned_by_user(sk) sctp_add_backlog(skb, sk); else inqueue_push(skb, sk); /* drop the ref on the assoc/ep */ However, in sctp_add_backlog() we take the ref on assoc/ep and hold it while the skb is on the backlog queue. This allows us to get rid of the sock_hold/sock_put in the lookup routines. Now sctp_backlog_rcv() needs to account for potential association move. In the unlikely event that association moved, we need to retest if the new socket is locked by user. If we don't this, we may have two packets racing up the stack toward the same socket and we can't deal with it. If the new socket is still locked, we'll just add the skb to its backlog continuing to hold the ref on the association. This get's rid of the need to move packets from one backlog to another and it also safe in case new packets arrive on the same backlog queue. The last step, is to lock the new socket when we are moving the association to it. This is needed in case any new packets arrive on the association when it moved. We want these to go to the backlog since we would like to avoid the race between this new packet and a packet that may be sitting on the backlog queue of the old socket toward the same association.

2006-05-19[NETFILTER]: Fix do_add_counters race, possible oops or info leak ↵Solar Designer
(CVE-2006-0039) Solar Designer found a race condition in do_add_counters(). The beginning of paddc is supposed to be the same as tmp which was sanity-checked above, but it might not be the same in reality. In case the integer overflow and/or the race condition are triggered, paddc->num_counters might not match the allocation size for paddc. If the check below (t->private->number != paddc->num_counters) nevertheless passes (perhaps this requires the race condition to be triggered), IPT_ENTRY_ITERATE() would read kernel memory beyond the allocation size, potentially causing an oops or leaking sensitive data (e.g., passwords from host system or from another VPS) via counter increments.

From: "Angelo P. Castellani" <angelo.castellani+lkml@gmail.com> Using NewReno, if a sk_buff is timed out and is accounted as lost_out, it should also be removed from the sacked_out. This is necessary because recovery using NewReno fast retransmit could take up to a lot RTTs and the sk_buff RTO can expire without actually being really lost. left_out = sacked_out + lost_out in_flight = packets_out - left_out + retrans_out Using NewReno without this patch, on very large network losses, left_out becames bigger than packets_out + retrans_out (!!).

2006-05-12[NEIGH]: Fix IP-over-ATM and ARP interaction.Simon Kelley
The classical IP over ATM code maintains its own IPv4 <-> <ATM stuff> ARP table, using the standard neighbour-table code. The neigh_table_init function adds this neighbour table to a linked list of all neighbor tables which is used by the functions neigh_delete() neigh_add() and neightbl_set(), all called by the netlink code. Once the ATM neighbour table is added to the list, there are two tables with family == AF_INET there, and ARP entries sent via netlink go into the first table with matching family. This is indeterminate and often wrong. To see the bug, on a kernel with CLIP enabled, create a standard IPv4 ARP entry by pinging an unused address on a local subnet. Then attempt to complete that entry by doing ip neigh replace <ip address> lladdr <some mac address> nud reachable Looking at the ARP tables by using ip neigh show will reveal two ARP entries for the same address. One of these can be found in /proc/net/arp, and the other in /proc/net/atm/arp. This patch adds a new function, neigh_table_init_no_netlink() which does everything the neigh_table_init() does, except add the table to the netlink all-arp-tables chain. In addition neigh_table_init() has a check that all tables on the chain have a distinct address family. The init call in clip.c is changed to call neigh_table_init_no_netlink(). Since ATM ARP tables are rather more complicated than can currently be handled by the available rtattrs in the netlink protocol, no functionality is lost by this patch, and non-ATM ARP manipulation via netlink is rescued. A more complete solution would involve a rtattr for ATM ARP entries and some way for the netlink code to give neigh_add and friends more information than just address family with which to find the correct ARP table. [ I've changed the assertion checking in neigh_table_init() to not use BUG_ON() while holding neigh_tbl_lock. Instead we remember that we found an existing tbl with the same family, and after dropping the lock we'll give a diagnostic kernel log message and a stack dump. -DaveM ] Signed-off-by: Simon Kelley <simon@thekelleys.org.uk> Signed-off-by: David S.

2006-05-05[DCCP]: Fix sock_orphan dead lockHerbert Xu
Calling sock_orphan inside bh_lock_sock in dccp_close can lead to dead locks. For example, the inet_diag code holds sk_callback_lock without disabling BH. If an inbound packet arrives during that admittedly tiny window, it will cause a dead lock on bh_lock_sock. Another possible path would be through sock_wfree if the network device driver frees the tx skb in process context with BH enabled. We can fix this by moving sock_orphan out of bh_lock_sock. The tricky bit is to work out when we need to destroy the socket ourselves and when it has already been destroyed by someone else. By moving sock_orphan before the release_sock we can solve this problem. This is because as long as we own the socket lock its state cannot change. So we simply record the socket state before the release_sock and then check the state again after we regain the socket lock. If the socket state has transitioned to DCCP_CLOSED in the time being, we know that the socket has been destroyed. Otherwise the socket is still ours to keep.

2006-05-05[SCTP]: Prevent possible infinite recursion with multiple bundled DATA.Vladislav Yasevich
There is a rare situation that causes lksctp to go into infinite recursion and crash the system. The trigger is a packet that contains at least the first two DATA fragments of a message bundled together. The recursion is triggered when the user data buffer is smaller that the full data message. The problem is that we clone the skb for every fragment in the message. When reassembling the full message, we try to link skbs from the "first fragment" clone using the frag_list. However, since the frag_list is shared between two clones in this rare situation, we end up setting the frag_list pointer of the second fragment to point to itself. This causes sctp_skb_pull() to potentially recurse indefinitely. Proposed solution is to make a copy of the skb when attempting to link things using frag_list.

2006-05-05[PATCH] softmac: make non-operational after being stoppedDaniel Drake
zd1211 with softmac and wpa_supplicant revealed an issue with softmac and the use of workqueues. Some of the work functions actually reschedule themselves, so this meant that there could still be pending work after flush_scheduled_work() had been called during ieee80211softmac_stop(). This patch introduces a "running" flag which is used to ensure that rescheduling does not happen in this situation. I also used this flag to ensure that softmac's hooks into ieee80211 are non-operational once the stop operation has been started. This simply makes softmac a little more robust, because I could crash it easily by receiving frames in the short timeframe after shutting down softmac and before turning off the ZD1211 radio.

Note that I've also moved the increment on the orphan count forward. This may look like a problem as we're increasing it even if the socket is just about to be destroyed where it'll be decreased again. However, this simply enlarges a window that already exists. This also changes the orphan count test by one. Considering what the orphan count is meant to do this is no big deal. This problem was discoverd by Ingo Molnar using his lock validator.
