patch 295b54c4 in mainline. Make sure and not dump reserved areas of device space. Touching some of these causes machine check exceptions on boards like D-Link DGE-550SX. Coding note, used a complex switch statement rather than bitmap because it is easier to relate the block values to the documentation rather than looking at a encoded bitmask. Signed-off-by:

patch ab5adecb in mainline. The D-Link PCI-X board (and maybe others) can lie about status ring entries. It seems it will update the register for last status index before completing the DMA for the ring entry. To avoid reading stale data, zap the old entry and check. 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 114342f2 in mainline. A performance regression was introduced by the following commit: commit ee6a99b5 Author: Michael Chan <mchan@broadcom.com> Date: Wed Jul 18 21:49:10 2007 -0700 [TG3]: Fix msi issue with kexec/kdump. In making that change, the PCI latency timer and cache line size registers were not restored after chip reset. On the 5705, the latency timer gets reset to 0 during chip reset and this causes very poor performance. Update version to 3.81.1 Signed-off-by:

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:

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). Fix by setting err = 0 after the vlan_dev_set_ingress_priority call. Signed-off-by:

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.

patch 94e10bfb in mainline. The MLME request reason code is host-endian and our passing it to the low level functions is host-endian as well since they do the swapping.

[TCP]: Fix size calculation in sk_stream_alloc_pskb [ Upstream commit: fb93134d ] We round up the header size in sk_stream_alloc_pskb so that TSO packets get zero tail room. Unfortunately this rounding up is not coordinated with the select_size() function used by TCP to calculate the second parameter of sk_stream_alloc_pskb. As a result, we may allocate more than a page of data in the non-TSO case when exactly one page is desired. In fact, rounding up the head room is detrimental in the non-TSO case because it makes memory that would otherwise be available to the payload head room. TSO doesn't need this either, all it wants is the guarantee that there is no tail room. So this patch fixes this by adjusting the skb_reserve call so that exactly the requested amount (which all callers have calculated in a precise way) is made available as tail room. Signed-off-by:

patch deea84b0 in mainline. [NET]: Fix SKB_WITH_OVERHEAD calculation The calculation in SKB_WITH_OVERHEAD is incorrect in that it can cause an overflow across a page boundary which is what it's meant to prevent. In particular, the header length (X) should not be lumped together with skb_shared_info. The latter needs to be aligned properly while the header has no choice but to sit in front of wherever the payload is. Therefore the correct calculation is to take away the aligned size of skb_shared_info, and then subtract the header length. The resulting quantity L satisfies the following inequality: SKB_DATA_ALIGN(L + X) + sizeof(struct skb_shared_info) <= PAGE_SIZE This is the quantity used by alloc_skb to do the actual allocation.

Reverted upstream by commit 6a22c57b Revert this commit: commit 2e1c49db Author: Zou Nan hai <nanhai.zou@intel.com> Date: Fri Jun 1 00:46:28 2007 -0700 x86_64: allocate sparsemem memmap above 4G This reverts commit 2e1c49db. First off, testing in Fedora has shown it to cause boot failures, bisected down by Martin Ebourne, and reported by Dave Jobes. So the commit will likely be reverted in the 2.6.23 stable kernels. Secondly, in the 2.6.24 model, x86-64 has now grown support for SPARSEMEM_VMEMMAP, which disables the relevant code anyway, so while the bug is not visible any more, it's become invisible due to the code just being irrelevant and no longer enabled on the only architecture that this ever affected.

patch edaf420f in mainline. I ran into this problem on a system that was unable to obtain NTP sync because the clock was running very slow (over 10000ppm slow). ntpd had declared all of its peers 'reject' with 'peer_dist' reason. On investigation, the tsc_khz variable was significantly incorrect causing xtime to run slow. After a reboot tsc_khz was correct so I did a reboot test to see how often the problem occurred: Test was done on a 2000 Mhz Xeon system. Of 689 reboots, 8 of them had unacceptable tsc_khz values (>500ppm): range of tsc_khz # of boots % of boots ---------------- ---------- ---------- < 1999750 0 0.000% 1999750 - 1999800 21 3.048% 1999800 - 1999850 166 24.128% 1999850 - 1999900 241 35.029% 1999900 - 1999950 211 30.669% 1999950 - 2000000 42 6.105% 2000000 - 2000000 0 0.000% 2000050 - 2000100 0 0.000% [...] 2000100 - 2015000 1 0.145% << BAD 2015000 - 2030000 6 0.872% << BAD 2030000 - 2045000 1 0.145% << BAD 2045000 < 0 0.000% The worst boot was 2032.577 Mhz, over 1.5% off! It appears that on rare occasions, mach_countup() is taking longer to complete than necessary. I suspect that this is caused by the CPU taking a periodic SMI interrupt right at the end of the 30ms calibration loop. This would cause the loop to delay while the SMI BIOS hander runs. The resulting TSC value is beyond what it actually should be resulting in a higher tsc_khz. The below patch makes native_calculate_cpu_khz() take the best (shortest duration, lowest khz) run of it's 3 calibration loops. If a SMI goes off causing a bad result (long duration, higher khz) it will be discarded. With the patch applied, 300 boots of the same system produce good results: range of tsc_khz # of boots % of boots ---------------- ---------- ---------- < 1999750 0 0.000% 1999750 - 1999800 30 10.000% 1999800 - 1999850 166 55.333% 1999850 - 1999900 89 29.667% 1999900 - 1999950 15 5.000% 1999950 < 0 0.000% Problem was found and tested against 2.6.18.
