2008-01-11[SCSI] libiscsi, iscsi_tcp: iscsi pool cleanupOlaf Kirch
iscsi_pool_init simplified iscsi_pool_init currently has a lot of duplicate kfree() calls it does when some allocation fails. This patch simplifies the code a little by using iscsi_pool_free to tear down the pool in case of an error. iscsi_pool_init also returns a copy of the item array to the caller. Not all callers use this array, so we make it optional. Instead of allocating a second array and return that, allocate just one array, of twice the size. Update users of iscsi_pool_{init,free} This patch drops the (now useless) second argument to iscsi_pool_free, and updates all callers. It also removes the ctask->r2ts array, which was never used anyway. Since the items argument to iscsi_pool_init is now optional, we can pass NULL instead.

2008-01-11[SCSI] iscsi_tcp, libiscsi: initial AHS SupportBoaz Harrosh
at libiscsi generic code - currently code assumes a storage space of pdu header is allocated at llds ctask and is pointed to by iscsi_cmd_task->hdr. Here I add a hdr_max field pertaining to that storage, and an hdr_len that accumulates the current use of the pdu-header. - Add an iscsi_next_hdr() inline which returns the next free space to write new Header at. Also iscsi_next_hdr() is used to retrieve the address at which to write the header-digest. - Add iscsi_add_hdr(length). What the user do is calls iscsi_next_hdr() for address of the new header, than calls iscsi_add_hdr(length) with the size of the new header. iscsi_add_hdr() will check if space is available and update to the new size. length must be padded according to standard. - Add 2 padding inline helpers thanks to Olaf. Current patch does not use them but Following patches will. Also moved definition of ISCSI_PAD_LEN to iscsi_proto.h which had PAD_WORD_LEN that was never used anywhere. - Let iscsi_prep_scsi_cmd_pdu() signal an Error return since now it is possible that it will fail. - I was tired of yet again writing a "this is a digest" comment next to sizeof(__u32) so I defined a new ISCSI_DIGEST_SIZE. Now I don't need any comments. Changed all places that used sizeof(__u32) or "4" in connection to a digest. iscsi_tcp specific code - At struct iscsi_tcp_cmd_task allocate maximum space allowed in standard for all headers following the iscsi_cmd header. and mark it so in iscsi_tcp_session_create() - At iscsi_send_cmd_hdr() retrieve the correct headers size and write header digest at iscsi_next_hdr().

2008-01-11[SCSI] move single_lun flag from scsi_device to scsi_targetTony Battersby
Some SCSI tape medium changers that need the BLIST_SINGLELUN flag have the medium changer at one LUN and the tape drive at a different LUN. The inquiry string of the tape drive may be different from that of the medium changer. In order for single_lun to be effective, every scsi_device under a given scsi_target must have it set. This means that there needs to be a blacklist entry for BOTH the medium changer AND the tape drive, which is impractical because some medium changers may be paired with a variety of different tape drive models. It makes more sense to put the single_lun flag in scsi_target instead of scsi_device, which causes every device at a given target ID to inherit the single_lun flag from one LUN. This makes it possible to blacklist just the medium changer and not the tape drive.

2008-01-08[NET]: Clone the sk_buff 'iif' field in __skb_clone()Paul Moore
Both NetLabel and SELinux (other LSMs may grow to use it as well) rely on the 'iif' field to determine the receiving network interface of inbound packets. Unfortunately, at present this field is not preserved across a skb clone operation which can lead to garbage values if the cloned skb is sent back through the network stack. This patch corrects this problem by properly copying the 'iif' field in __skb_clone() and removing the 'iif' field assignment from skb_act_clone() since it is no longer needed. Also, while we are here, put the assignments in the same order as the offsets to reduce cacheline bounces. Signed-off-by: Paul Moore <paul.moore@hp.com> Signed-off-by: David S.

2008-01-08[NET]: Add NAPI_STATE_DISABLE.David S. Miller
Create a bit to signal that a napi_disable() is in progress. This sets up infrastructure such that net_rx_action() can generically break out of the ->poll() loop on a NAPI context that has a pending napi_disable() yet is being bombed with packets (and thus would otherwise poll endlessly and not allow the napi_disable() to finish). Now, what napi_disable() does is first set the NAPI_STATE_DISABLE bit (to indicate that a disable is pending), then it polls for the NAPI_STATE_SCHED bit, and once the NAPI_STATE_SCHED bit is acquired the NAPI_STATE_DISABLE bit is cleared. Here, the test_and_set_bit() provides the necessary memory barrier between the various bitops. napi_schedule_prep() now tests for a pending disable as it's first action and won't try to obtain the NAPI_STATE_SCHED bit if a disable is pending. As a result, we can remove the netif_running() check in netif_rx_schedule_prep() because the NAPI disable pending state serves this purpose. And, it does so in a NAPI centric manner which is what we really want. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-01-08[NET]: Do not grab device reference when scheduling a NAPI poll.David S. Miller
It is pointless, because everything that can make a device go away will do a napi_disable() first. The main impetus behind this is that now we can legally do a NAPI completion in generic code like net_rx_action() which a following changeset needs to do. net_rx_action() can only perform actions in NAPI centric ways, because there may be a one to many mapping between NAPI contexts and network devices (SKY2 is one example). We also want to get rid of this because it's an extra atomic in the NAPI paths, and also because it is one of the last instances where the NAPI interfaces care about net devices. The one remaining netdev detail the NAPI stuff cares about is the netif_running() check which will be killed off in a subsequent changeset. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-01-06CPU hotplug: fix cpu_is_offline() on !CONFIG_HOTPLUG_CPUIngo Molnar
make randconfig bootup testing found that the cpufreq code crashes on bootup, if the powernow-k8 driver is enabled and if maxcpus=1 passed on the boot line to a !CONFIG_HOTPLUG_CPU kernel. First lockdep found out that there's an inconsistent unlock sequence: ===================================== [ BUG: bad unlock balance detected! ] ------------------------------------- swapper/1 is trying to release lock (&per_cpu(cpu_policy_rwsem, cpu)) at: [<ffffffff806ffd8e>] unlock_policy_rwsem_write+0x3c/0x42 but there are no more locks to release!

This opened up the possibility to add the non-initialized sysdev device of the secondary core: cpufreq-core: trying to register driver powernow-k8 cpufreq-core: adding CPU 0 powernow-k8: BIOS error - no PSB or ACPI _PSS objects cpufreq-core: initialization failed cpufreq-core: adding CPU 1 cpufreq-core: initialization failed which then blew up. The fix is to make cpu_is_offline() always the negation of cpu_online(). With that fix applied the kernel boots up fine without crashing: Calling initcall 0xffffffff80cc0510: powernowk8_init+0x0/0x94() powernow-k8: Found 1 AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ processors (1 cpu cores) (version 2.20.00) powernow-k8: BIOS error - no PSB or ACPI _PSS objects initcall 0xffffffff80cc0510: powernowk8_init+0x0/0x94() returned -19. initcall 0xffffffff80cc0510 ran for 19 msecs: powernowk8_init+0x0/0x94() Calling initcall 0xffffffff80cc328f: init_lapic_nmi_sysfs+0x0/0x39() We could fix this by making CPU enumeration aware of max_cpus, but that would be more fragile IMO, and the cpu_online(cpu) != cpu_is_offline(cpu) possibility was quite confusing and a continuous source of bugs too. Most distributions have kernels with CPU hotplug enabled, so this bug remained hidden for a long time. Bug forensics: The broken cpu_is_offline() API variant was introduced via: commit a59d2e4e6977e7b94e003c96a41f07e96cddc340 Author: Rusty Russell <rusty@rustcorp.com.au> Date: Mon Mar 8 06:06:03 2004 -0800 [PATCH] minor cleanups for hotplug CPUs ( this predates linux-2.6.git, this commit is available from Thomas's historic git tree. ) Then 1.5 years later the cpufreq code made use of it: commit c32b6b8e524d2c337767d312814484d9289550cf Author: Ashok Raj <ashok.raj@intel.com> Date: Sun Oct 30 14:59:54 2005 -0800 [PATCH] create and destroy cpufreq sysfs entries based on cpu notifiers + if (cpu_is_offline(cpu)) + return 0; which is a correct use of the subtly broken new API. v2.6.15 then shipped with this bug included. then it took two more years for random-kernel qa to hit it.

2008-01-06Revert "scsi: revert "[SCSI] Get rid of scsi_cmnd->done""Linus Torvalds
This reverts commit ac40532ef0b8649e6f7f83859ea0de1c4ed08a19, which gets us back the original cleanup of 6f5391c283d7fdcf24bf40786ea79061919d1e1d. 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).

2007-12-26Revert quicklist need->flush fixChristoph Lameter
Did not fix the reported issue. Apart from other weirdness this causes a bad link between the TLB flushing logic and the quicklists. If there is indeed an issue that an arch needs a tlb flush before free then the arch code needs to set tlb->need_flush before calling quicklist_free.

2007-12-26[NETFILTER]: nf_conntrack_ipv4: fix module parameter compatibilityPatrick McHardy
Some users do "modprobe ip_conntrack hashsize=...". Since we have the module aliases this loads nf_conntrack_ipv4 and nf_conntrack, the hashsize parameter is unknown for nf_conntrack_ipv4 however and makes it fail. Allow to specify hashsize= for both nf_conntrack and nf_conntrack_ipv4. Note: the nf_conntrack message in the ringbuffer will display an incorrect hashsize since nf_conntrack is first pulled in as a dependency and calculates the size itself, then it gets changed through a call to nf_conntrack_set_hashsize().

This patch reads the error detail bits from the proper location, so the correct BTE failure reason is returned for both shub1 and shub2.
