patch c480f79b in mainline [ALSA] hda-codec - Avoid zero NID in line_out_pins[] of STAC codecs The STAC codes adds line_out_pins[] for shared mic/line-inputs accordingly. But, the current code may give a hole with NID=0 in some setting, which results in an error at probe. This patch fixes the problem. Signed-off-by:

Upstream as 76d7cc03 Firmware commands are sent to the HCA by writing multiple words to a command register block. Access to this block of registers is serialized with a mutex. However, on large SGI systems, problems were seen with multiple CPUs issuing FW commands at the same time, because the writes to the register block may be reordered within the system interconnect and reach the HCA in a different order than they were issued (even with the mutex). Fix this by adding an mmiowb() before dropping the mutex. Tested-by:

Upstream as cbfb50e6 Commit 9ead190b ("IB/uverbs: Don't serialize with ib_uverbs_idr_mutex") rewrote how userspace objects are looked up in the uverbs module's idrs, and introduced a severe bug in the process: there is no checking that an operation is being performed by the right process any more. Fix this by adding the missing check of uobj->context in __idr_get_uobj(). Apparently everyone is being very careful to only touch their own objects, because this bug was introduced in June 2006 in 2.6.18, and has gone undetected until now. Signed-off-by:

This might not be the case. This is exactly the same bug as was fixed in the w83627ehf driver two months ago: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=0956895aa6f8dc6a33210967252fd7787652537d In practice, this bug was causing the sensor thermal types to be improperly reported for my W83627THF the first time I was loading the w83627hf driver. From the driver history, I'd say that it has been broken since September 2005 (when we stopped resetting the chip by default at driver load.) Signed-off-by:

changeset 91781004 in mainline. [PPP]: L2TP: Fix oops in transmit and receive paths Changes made on 18-sep to fix skb handling in the pppol2tp driver broke the transmit and receive paths. Users are only running into this now because distros are now using 2.6.23 and I must have messed up when I tested the change. For receive, we now do our own calculation of how much to pull from the skb (variable length L2TP header) rather than using skb_transport_offset(). Also, if the skb isn't a data packet, it must be passed back to UDP with skb->data pointing to the UDP header. For transmit, make sure skb->sk is set up because ip_queue_xmit() needs it.

patch a7475906 in mainline. pci_enable_msi() replaces the INTx irq number in pci_dev->irq with the new MSI irq number. The forcedeth driver did not update the copy in netdevice->irq and parts of the driver used the stale copy. See bugzilla.kernel.org, bug 9047. The patch - updates netdevice->irq - replaces all accesses to netdevice->irq with pci_dev->irq. The patch is against 2.6.23.1. IMHO suitable for both 2.6.23 and 2.6.24 Signed-off-by:

patch 67a4cce4 in mainline. Some APs send management frames with junk padding after the last IE. We already account for a similar problem with some Apple Airport devices, but at least one device is known to send more than a single extra byte. The device in question is the Draytek Vigor2900: http://www.draytek.com.au/products/Vigor2900.php The junk in question looks like an IE that runs off the end of the frame. This cause us to return ParseFailed. Since the frame in question is an association response, this causes us to fail to associate with this AP. The return code from ieee802_11_parse_elems is superfluous. All callers still check for the presence of the specific IEs that interest them anyway. So, remove the return code so the parse never "fails". Acked-by:

Somehow I was able to misread RFC1122 and mixed the roles :-(: When a connection is >>closed actively<<, it MUST linger in TIME-WAIT state for a time 2xMSL (Maximum Segment Lifetime). However, it MAY >>accept<< a new SYN from the remote TCP to reopen the connection directly from TIME-WAIT state, if it: [...] The fix is as follows: if the receiver initiated an active close, then the sender may reopen the connection - otherwise try to figure out if we hold a dead connection.

[NETLINK]: Fix unicast timeouts [ Upstream commit: c3d8d1e3 ] Commit ed6dcf4a in the history.git tree broke netlink_unicast timeouts by moving the schedule_timeout() call to a new function that doesn't propagate the remaining timeout back to the caller. This means on each retry we start with the full timeout again. ipc/mqueue.c seems to actually want to wait indefinitely so this behaviour is retained. Signed-off-by:

patch fffe470a in mainline. [VLAN]: Fix SET_VLAN_INGRESS_PRIORITY_CMD ioctl Based on report and patch by Doug Kehn <rdkehn@yahoo.com>: vconfig returns the following error when attempting to execute the set_ingress_map command: vconfig: socket or ioctl error for set_ingress_map: Operation not permitted In vlan.c, vlan_ioctl_handler for SET_VLAN_INGRESS_PRIORITY_CMD sets err = -EPERM and calls vlan_dev_set_ingress_priority. vlan_dev_set_ingress_priority is a void function so err remains at -EPERM and results in the vconfig error (even though the ingress map was set).

changeset 543821c6 in mainline. [PKT_SCHED] CLS_U32: Fix endianness problem with u32 classifier hash masks. While trying to implement u32 hashes in my shaping machine I ran into a possible bug in the u32 hash/bucket computing algorithm (net/sched/cls_u32.c). The problem occurs only with hash masks that extend over the octet boundary, on little endian machines (where htonl() actually does something). Let's say that I would like to use 0x3fc0 as the hash mask. This means 8 contiguous "1" bits starting at b6. With such a mask, the expected (and logical) behavior is to hash any address in, for instance, 192.168.0.0/26 in bucket 0, then any address in 192.168.0.64/26 in bucket 1, then 192.168.0.128/26 in bucket 2 and so on. This is exactly what would happen on a big endian machine, but on little endian machines, what would actually happen with current implementation is 0x3fc0 being reversed (into 0xc03f0000) by htonl() in the userspace tool and then applied to 192.168.x.x in the u32 classifier. When shifting right by 16 bits (rank of first "1" bit in the reversed mask) and applying the divisor mask (0xff for divisor 256), what would actually remain is 0x3f applied on the "168" octet of the address. One could say is this can be easily worked around by taking endianness into account in userspace and supplying an appropriate mask (0xfc03) that would be turned into contiguous "1" bits when reversed (0x03fc0000). But the actual problem is the network address (inside the packet) not being converted to host order, but used as a host-order value when computing the bucket. Let's say the network address is written as n31 n30 ... n0, with n0 being the least significant bit. When used directly (without any conversion) on a little endian machine, it becomes n7 ... n0 n8 ..n15 etc in the machine's registers. Thus bits n7 and n8 would no longer be adjacent and 192.168.64.0/26 and 192.168.128.0/26 would no longer be consecutive. The fix is to apply ntohl() on the hmask before computing fshift, and in u32_hash_fold() convert the packet data to host order before shifting down by fshift. With helpful feedback from Jamal Hadi Salim and Jarek Poplawski. Signed-off-by:
