* SUNRPC: NFS_ROOT always uses the same XIDsChuck Lever2006-06-09
| | | | | | | | | | | | | | | | | | The XID generator uses get_random_bytes to generate an initial XID. NFS_ROOT starts up before the random driver, though, so get_random_bytes doesn't set a random XID for NFS_ROOT. This causes NFS_ROOT mount points to reuse XIDs every time the client is booted. If the client boots often enough, the server will start serving old replies out of its DRC. Use net_random() instead. Test plan: I/O intensive workloads should perform well and generate no errors. Traces taken during client reboots should show that NFS_ROOT mounts use unique XIDs after every reboot.

* SUNRPC: select privileged port numbers at randomChuck Lever2006-06-09
| | | | | | | | | | | | | | | | | | | Make the RPC client select privileged ephemeral source ports at random. This improves DRC behavior on the server by using the same port when reconnecting for the same mount point, but using a different port for fresh mounts. The Linux TCP implementation already does this for nonprivileged ports. Note that TCP sockets in TIME_WAIT will prevent quick reuse of a random ephemeral port number by leaving the port INUSE until the connection transitions out of TIME_WAIT. Test plan: Connectathon against every known server implementation using multiple mount points. Locking especially.

* [TCP]: Avoid skb_pull if possible when trimming headHerbert Xu ~{PmVHI~}2006-06-05
| | | | | | | | | | | | | | | | | | | | | | Trimming the head of an skb by calling skb_pull can cause the packet to become unaligned if the length pulled is odd. Since the length is entirely arbitrary for a FIN packet carrying data, this is actually quite common. Unaligned data is not the end of the world, but we should avoid it if it's easily done. In this case it is trivial. Since we're discarding all of the head data it doesn't matter whether we move skb->data forward or back. However, it is still possible to have unaligned skb->data in general. So network drivers should be prepared to handle it instead of crashing. This patch also adds an unlikely marking on len < headlen since partial ACKs on head data are extremely rare in the wild. As the return value of __pskb_trim_head is no longer ever NULL that has been removed. Signed-off-by: Herbert Xu ~{PmV>HI~} <herbert@gondor.apana.org.au> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [NETFILTER]: Fix do_add_counters race, possible oops or info leak ↵Solar Designer2006-05-19
| | | | | | | | | | | | | | | | | | | | (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.

* [NEIGH]: Fix IP-over-ATM and ARP interaction.Simon Kelley2006-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [PATCH] softmac: make non-operational after being stoppedDaniel Drake2006-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. (ZD1211 is now fixed as well!) Signed-off-by: Daniel Drake <dsd@gentoo.org> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
| * [PATCH] softmac: don't reassociate if user asked for deauthenticationDaniel Drake2006-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | When wpa_supplicant exits, it uses SIOCSIWMLME to request deauthentication. softmac then tries to reassociate without any user intervention, which isn't the desired behaviour of this signal. This change makes softmac only attempt reassociation if the remote network itself deauthenticated us.

* | [IPV4]: Remove likely in ip_rcv_finish()Hua Zhong2006-05-06
| | | | | | | | | | | | | | | | | | | | | | | | This is another result from my likely profiling tool (dwalker@mvista.com just sent the patch of the profiling tool to linux-kernel mailing list, which is similar to what I use). On my system (not very busy, normal development machine within a VMWare workstation), I see a 6/5 miss/hit ratio for this "likely". Signed-off-by: Hua Zhong <hzhong@gmail.com> Signed-off-by: David S.

This avoids the race between registering class_device (which generates hotplug event), and the creation of attribute groups.
