| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous patch fixed spurious read faults from occuring by copying the data if we happen to have a single block at the end of a page. It appears that gcc cannot guarantee 16-byte alignment in the kernel with __attribute__. The following report from Torben Viets shows a buffer that's only 8-byte aligned: > eneral protection fault: 0000 [#1] > Modules linked in: xt_TCPMSS xt_tcpmss iptable_mangle ipt_MASQUERADE > xt_tcpudp xt_mark xt_state iptable_nat nf_nat nf_conntrack_ipv4 > iptable_filter ip_tables x_tables pppoe pppox af_packet ppp_generic slhc > aes_i586 > CPU: 0 > EIP: 0060:[<c035b828>] Not tainted VLI > EFLAGS: 00010292 (2.6.23.12 #7) > EIP is at aes_crypt_copy+0x28/0x40 > eax: f7639ff0 ebx: f6c24050 ecx: 00000001 edx: f6c24030 > esi: f7e89dc8 edi: f7639ff0 ebp: 00010000 esp: f7e89dc8 Since the hardware must have 16-byte alignment, the following patch fixes this by open coding the alignment adjustment.

| * | libata: don't normalize UNKNOWN to NONE after resetTejun Heo2008-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After non-classifying reset, ehc->classes[] could contain ATA_DEV_UNKNOWN which used to be normalized to ATA_DEV_NONE for consistency. However, this causes unfortunate side effect for drivers which have non-classifying hardresets (e.g. sata_nv) by making hardreset report ATA_DEV_NONE for non-classifying resets and thus makes EH believe that the port is unoccupied and recovery can be skipped. The end result is that after a device is swapped with another one, the new device isn't attached after the old one is detached. This patch makes ata_eh_reset() not normalize UNKNOWN to NONE after non-classifying resets. This fixes the above problem. As UNKNOWN and NONE are handled differently by only EH hotplug logic, this doesn't cause other behavior changes.

* | [FORCEDETH]: Fix reversing the MAC address on suspend.Björn Steinbrink2008-01-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For cards that initially have the MAC address stored in reverse order, the forcedeth driver uses a flag to signal whether the address was already corrected, so that it is not reversed again on a subsequent probe. Unfortunately this flag, which is stored in a register of the card, seems to get lost during suspend, resulting in the MAC address being reversed again. To fix that, the MAC address needs to be written back in reversed order before we suspend and the flag needs to be reset. The flag is still required because at least kexec will never write back the reversed address and thus needs to know what state the card is in.

* | [NET]: Make ->poll() breakout consistent in Intel ethernet drivers.David S. Miller2008-01-09

Now they will all break out when the amount of RX work done is less than 'budget'. At a later time, we may want put back code to include the TX work as well (as at least one other NAPI driver does, but by in large NAPI drivers do not do this). But if so, it should be done consistently across the board to all of these drivers. Signed-off-by: David S. Miller <davem@davemloft.net> Acked-by: Auke Kok <auke-jan.h.kok@intel.com>
* | [NET]: Fix drivers to handle napi_disable() disabling interrupts.David S. Miller2008-01-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we add the generic napi_disable_pending() breakout logic to net_rx_action() it means that napi_disable() can cause NAPI poll interrupt events to be disabled. And this is exactly what we want. If a napi_disable() is pending, and we are looping in the ->poll(), we want ->poll() event interrupts to stay disabled and we want to complete the NAPI poll ASAP. When ->poll() break out during device down was being handled on a per-driver basis, often these drivers would turn interrupts back on when '!netif_running()' was detected. And this would just cause a reschedule of the NAPI ->poll() in the interrupt handler before the napi_disable() could get in there and grab the NAPI_STATE_SCHED bit. The vast majority of drivers don't care if napi_disable() might have the side effect of disabling NAPI ->poll() event interrupts. In all such cases, when a napi_disable() is performed, the driver just disabled interrupts or is about to. However there were three exceptions to this in PCNET32, R8169, and SKY2. To fix those cases, at the subsequent napi_enable() points, I added code to ensure that the ->poll() interrupt events are enabled in the hardware. Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is possible for the TX ring to have packets sit in it for unbounded amounts of time. The only way to defer TX interrupts in the chip is to periodically set "mark" bits, when processing of a TX descriptor with the mark bit set is complete it triggers the interrupt for the TX queue's LDG. A consequence of this kind of scheme is that if packet flow suddenly stops, the remaining TX packets will just sit there. If this happens, since those packets could be charged to TCP socket send queues, such sockets could get stuck. The simplest solution is to divorce the socket ownership of the packet once the device takes the SKB, by using skb_orphan() in niu_start_xmit(). In hindsight, it would have been much nicer if the chip provided two interrupt sources for TX (like basically every other ethernet chip does). Namely, keep the "mark" bit, but also signal the LDG when the TX queue becomes completely empty. That way there is no need to have a deadlock breaker like this. Signed-off-by: David S.

It turns out that the bug that was triggered by that commit was apparently not actually triggered by that commit at all, and just the testing conditions had changed enough to make it appear to be due to it. The real problem seems to have been found by Peter Osterlund: "pktcdvd sets it [block device size] when opening the /dev/pktcdvd device, but when the drive is later opened as /dev/scd0, there is nothing that sets it back. (Btw, 40944 is possible if the disk is a CDRW that was formatted with "cdrwtool -m 10236".) The problem is that pktcdvd opens the cd device in non-blocking mode when pktsetup is run, and doesn't close it again until pktsetup -d is run. The effect is that if you meanwhile open the cd device, blkdev.c:do_open() doesn't call bd_set_size() because bdev->bd_openers is non-zero." In particular, to repeat the bug (regardless of whether commit 6f5391c283d7fdcf24bf40786ea79061919d1e1d is applied or not): " 1. Start with an empty drive. 2. pktsetup 0 /dev/scd0 3. Insert a CD containing an isofs filesystem. 4. mount /dev/pktcdvd/0 /mnt/tmp 5. umount /mnt/tmp 6. Press the eject button. 7. Insert a DVD containing a non-writable filesystem. 8. mount /dev/scd0 /mnt/tmp 9. find /mnt/tmp -type f -print0 | xargs -0 sha1sum >/dev/null 10. If the DVD contains data beyond the physical size of a CD, you get I/O errors in the terminal, and dmesg reports lots of "attempt to access beyond end of device" errors." which in turn is because the nested open after the media change won't cause the size to be set properly (because the original open still holds the block device, and we only do the bd_set_size() when we don't have other people holding the device open). The proper fix for that is probably to just do something like bdev->bd_inode->i_size = (loff_t)get_capacity(disk)<<9; in fs/block_dev.c:do_open() even for the cases where we're not the original opener (but *not* call bd_set_size(), since that will also change the block size of the device).

* | [SCSI] SRP transport: only remove our own entriesDave Dillow2008-01-04
| | | | | | | | | | | | | | | | | | | | | | | | The SCSI SRP transport class currently iterates over all children devices of the host that is being removed in srp_remove_host(). However, not all of those children were created by the SRP transport, and removing them will cause corruption and an oops when their creator tries to remove them.

* | [ISDN]: i4l: Fix DLE handling for i4l-audioMatthias Goebl2008-01-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DLE handling in i4l-audio seems to be broken. It produces spurious DLEs so asterisk 1.2.24 with chan_modem_i4l gets irritated, the error message is: "chan_modem_i4l.c:450 i4l_read: Value of escape is ^ (17)". -> There shouldn't be a DLE-^. If a spurious DLE-ETX occurs, the audio connection even dies. I use a "AVM Fritz!PCI" isdn card. I found two issues that only appear if ISDN_AUDIO_SKB_DLECOUNT(skb) > 0: - The loop in isdn_tty.c:isdn_tty_try_read() doesn't escape a DLE if it's the last character. - The loop in isdn_common.c:isdn_readbchan_tty() doesn't copy its characters, it only remembers the last one ("last = *p;"). Compare it with the loop in isdn_common.c:isdn_readbchan(), that *does* copy them ("*cp++ = *p;") correctly. The special handling of the "last" character made it more difficult. I compared it to linux-2.4.19: There was no "last"-handling and both loops did escape and copy all characters correctly.

* | [ISDN] i4l: 'NO CARRIER' message lost after ldisc flushMatthias Goebl2008-01-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ISDN tty layer doesn't produce a 'NO CARRIER' message after hangup. I suppose it broke when tty_buffer_flush() has been added to tty_ldisc_flush() in the commit below. For isdn_tty_modem_result(RESULT_NO_CARRIER..) the message inserted via isdn_tty_at_cout() -> tty_insert_flip_char() is flushed immediately by tty_ldisc_flush() -> tty_buffer_flush(). More annoyingly, the audio abort sequence DLE-ETX is also lost. This patch fixes only active audio connections, because I assume that nobody changes the line discipline for audio. For non-audio connections the problem remains. Maybe we can remove the tty_ldisc_flush() in isdn_tty_modem_result() at all because it's done at tty_close?
