* [DCCP] ipv6: dccp_v6_send_response() has a DST leak too.David S. Miller2006-02-011-0/+1
| | | | | | | | | It was copy&pasted from tcp_v6_send_synack() which has a DST leak recently fixed by Eric W. Biederman. So dccp_v6_send_response() needs the same fix too. Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPV6] tcp_v6_send_synack: release the destinationEric W. Biederman2006-02-011-0/+1
| | | | | | | | | | | | | | | | | | | | This patch fix dst reference counting in tcp_v6_send_synack Analysis: Currently tcp_v6_send_synack is never called with a dst entry so dst always comes in as NULL. ip6_dst_lookup calls ip6_route_output which calls dst_hold before it returns the dst entry. Neither xfrm_lookup nor tcp_make_synack consume the dst entry so we still have a dst_entry with a bumped refrence count at the end of this function. Therefore we need to call dst_release just before we return just like tcp_v4_send_synack does. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S.

* [BRIDGE]: Fix device delete race.Stephen Hemminger2006-02-012-6/+16
| | | | | | | | | | | | This is a simpler fix for the two races in bridge device removal. The Xen race of delif and notify is managed now by a new deleted flag. No need for barriers or other locking because of rtnl mutex. The del_timer_sync()'s are unnecessary, because br_stp_disable_port delete's the timers, and they will finish running before RCU callback.

* [IPV4]: Always set fl.proto in ip_route_newportsPatrick McHardy2006-02-012-2/+3
| | | | | | | | | | | ip_route_newports uses the struct flowi from the struct rtable returned by ip_route_connect for the new route lookup and just replaces the port numbers if they have changed. If an IPsec policy exists which doesn't match port 0 the struct flowi won't have the proto field set and no xfrm lookup is done for the changed ports.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following patch fixes these problems in MLDv2: 1) Add/remove "delete" records for sending change reports when addition of a filter results in that filter transitioning to/from inactive. [same as recent IPv4 IGMPv3 fix] 2) Remove 2 redundant "group_type" checks (can't be IPV6_ADDR_ANY within that loop, so checks are always true) 3) change an is_in() "return 0" to "return type == MLD2_MODE_IS_INCLUDE". It should always be "0" to get here, but it improves code locality to not assume it, and if some race allowed otherwise, doing the check would return the correct result.

| * [SCTP]: Fix machine check/connection hang on IA64.Vlad Yasevich2006-01-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sctp_unpack_cookie used an on-stack array called digest as a result/out parameter in the call to crypto_hmac. However, hmac code (crypto_hmac_final) assumes that the 'out' argument is in virtual memory (identity mapped region) and can use virt_to_page call on it. This does not work with the on-stack declared digest. The problems observed so far have been: a) incorrect hmac digest b) machine check and hardware reset. Solution is to define the digest in an identity mapped region by kmalloc'ing it. We can do this once as part of the endpoint structure and re-use it when verifying the SCTP cookie.

| | | | | | | | | | | | | | | | | | | | | | | | This patch corrects the panic by casting the argument to the pointer of correct size. On big-endian systems we ended up loading only 32 bits of data because we are treating the pointer as an int*. By treating this pointer as loff_t*, we'll load the full 64 bits and then let regular integer demotion take place which will give us the correct value.

| * [SCTP]: sctp doesn't show all associations/endpoints in /procVlad Yasevich2006-01-171-18/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When creating a very large number of associations (and endpoints), /proc/assocs and /proc/eps will not show all of them. As a result netstat will not show all of the either. This is particularly evident when creating 1000+ associations (or endpoints). As an example with 1500 tcp style associations over loopback, netstat showed 1420 on my system instead of 3000. The reason for this is that the seq_operations start method is invoked multiple times bacause of the amount of data that is provided. The start method always increments the position parameter and since we use the position as the hash bucket id, we end up skipping hash buckets. This patch corrects this situation and get's rid of the silly hash-1 decrement. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: Sridhar Samudrala <sri@us.ibm.com>
| * [SCTP]: Fix sctp_cookie alignment in the packet.Vlad Yasevich2006-01-171-2/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On 64 bit architectures, sctp_cookie sent as part of INIT-ACK is not aligned on a 64 bit boundry and thus causes unaligned access exceptions. The layout of the cookie prameter is this: |<----- Parameter Header --------------------|<--- Cookie DATA -------- ----------------------------------------------------------------------- | param type (16 bits) | param len (16 bits) | sig [32 bytes] | cookie.. ----------------------------------------------------------------------- The cookie data portion contains 64 bit values on 64 bit architechtures (timeval) that fall on a 32 bit alignment boundry when used as part of the on-wire format, but align correctly when used in internal structures.

* | [PATCH] EDAC: atomic scrub operationsAlan Cox2006-01-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | EDAC requires a way to scrub memory if an ECC error is found and the chipset does not do the work automatically. That means rewriting memory locations atomically with respect to all CPUs _and_ bus masters. That means we can't use atomic_add(foo, 0) as it gets optimised for non-SMP This adds a function to include/asm-foo/atomic.h for the platforms currently supported which implements a scrub of a mapped block. It also adjusts a few other files include order where atomic.h is included before types.h as this now causes an error as atomic_scrub uses u32.
