* [TG3]: 40-bit DMA workaround part 2Michael Chan2006-03-19
| | | | | | | | | | | | | | | | | The 40-bit DMA workaround recently implemented for 5714, 5715, and 5780 needs to be expanded because there may be other tg3 devices behind the EPB Express to PCIX bridge in the 5780 class device. For example, some 4-port card or mother board designs have 5704 behind the 5714. All devices behind the EPB require the 40-bit DMA workaround. Thanks to Chris Elmquist again for reporting the problem and testing the patch. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [AX.25]: Fix potencial memory hole.Ralf Baechle DL5RB2006-03-19
| | | | | | | | | | | | | | | | | | If the AX.25 dialect chosen by the sysadmin is set to DAMA master / 3 (or DAMA slave / 2, if CONFIG_AX25_DAMA_SLAVE=n) ax25_kick() will fall through the switch statement without calling ax25_send_iframe() or any other function that would eventually free skbn thus leaking the packet. Fix by restricting the sysctl inferface to allow only actually supported AX.25 dialects. The system administration mistake needed for this to happen is rather unlikely, so this is an uncritical hole.

* [PATCH] Kconfig: swap VIDEO_CX88_ALSA and VIDEO_CX88_DVBMichael Krufky2006-03-18
| | | | | | | | | | | | | | | | | VIDEO_CX88_ALSA should not be between VIDEO_CX88_DVB and VIDEO_CX88_DVB_ALL_FRONTENDS When cx88-alsa was added to cx88/Kconfig, it was added in between VIDEO_CX88_DVB and VIDEO_CX88_DVB_ALL_FRONTENDS. This caused undesireable effects to the appearance of the menu options in menuconfig. This fix reorders cx88-alsa and cx88-dvb in Kconfig, to match saa7134, and restore the correct menuconfig appearance.

* [PATCH] fix free swap cache latencyHugh Dickins2006-03-17
| | | | | | | | | | | | | | | | | | | | | | | | Lee Revell reported 28ms latency when process with lots of swapped memory exits. 2.6.15 introduced a latency regression when unmapping: in accounting the zap_work latency breaker, pte_none counted 1, pte_present PAGE_SIZE, but a swap entry counted nothing at all. We think of pages present as the slow case, but Lee's trace shows that free_swap_and_cache's radix tree lookup can make a lot of work - and we could have been doing it many thousands of times without a latency break. Move the zap_work update up to account swap entries like pages present. This does account non-linear pte_file entries, and unmap_mapping_range skipping over swap entries, by the same amount even though they're quick: but neither of those cases deserves complicating the code (and they're treated no worse than they were in 2.6.14).

* [PATCH] dm stripe: Fix boundsKevin Corry2006-03-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dm-stripe target currently does not enforce that the size of a stripe device be a multiple of the chunk-size. Under certain conditions, this can lead to I/O requests going off the end of an underlying device. This test-case shows one example. echo "0 100 linear /dev/hdb1 0" | dmsetup create linear0 echo "0 100 linear /dev/hdb1 100" | dmsetup create linear1 echo "0 200 striped 2 32 /dev/mapper/linear0 0 /dev/mapper/linear1 0" | \ dmsetup create stripe0 dd if=/dev/zero of=/dev/mapper/stripe0 bs=1k This will produce the output: dd: writing '/dev/mapper/stripe0': Input/output error 97+0 records in 96+0 records out And in the kernel log will be: attempt to access beyond end of device dm-0: rw=0, want=104, limit=100 The patch will check that the table size is a multiple of the stripe chunk-size when the table is created, which will prevent the above striped device from being created. This should not affect tools like LVM or EVMS, since in all the cases I can think of, striped devices are always created with the sizes being a multiple of the chunk-size. The size of a stripe device must be a multiple of its chunk-size.

* [PATCH] x86: check for online cpus before bringing them upSrivatsa Vaddagiri2006-03-17
| | | | | | | | | | | | | | | | Bryce reported a bug wherein offlining CPU0 (on x86 box) and then subsequently onlining it resulted in a lockup. On x86, CPU0 is never offlined. The subsequent attempt to online CPU0 doesn't take that into account. It actually tries to bootup the already booted CPU. Following patch fixes the problem (as acknowledged by Bryce).

There were two reasons: (1) when we recalculated the offsets used by gettimeofday every 2^31 timebase ticks, we lost an accumulated fractional microsecond, and (2) because the update is done some time after the notional start of jiffy, if ntp is slowing the clock, it is possible to see time go backwards when the timebase factor gets reduced. This fixes it by (a) slowing the gettimeofday clock by about 1us in 2^31 timebase ticks (a factor of less than 1 in 3.7 million), and (b) adjusting the timebase offsets in the rare case that the gettimeofday result could possibly go backwards (i.e. when ntp is slowing the clock and the timer interrupt is late). In this case the adjustment will reduce to zero eventually because of (a). Signed-off-by: Paul Mackerras <paulus@samba.org>

It also cleans up the code to avoid the unnecessary goto mess. The bugs were related to re-valiating the f_pos value after somebody had either done an "lseek()" on the directory to an invalid offset, or when the offset had become invalid due to a file being unlinked in the directory. The code would not only set the f_version too eagerly, it would also not update f_pos appropriately for when the offset fixup took place. When that happened, we'd occasionally subsequently fail the readdir() even when we shouldn't (no real harm done, but an ugly printk, and obviously you would end up not necessarily seeing all entries). Thanks to Masoud Sharbiani <masouds@google.com> who noticed the problem and had a test-case for it, and also fixed up a thinko in the first version of this patch.

* | [PATCH] Consistent capabilites associated with MPOL_MOVE_ALLChristoph Lameter2006-03-15
| | | | | | | | | | | | | | | | | | | | | | | | | | It seems that setting scheduling policy and priorities is also the kind of thing that might be performed in apps that also use the NUMA API, so it would seem consistent to use CAP_SYS_NICE for NUMA also. So use CAP_SYS_NICE for controlling migration permissions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the documentation for page migration. - Fix up bits and pieces in cpusets.txt - Rework text in vm/page-migration to be clearer and reflect the final version of page migration in 2.6.16. Mention Andi Kleen's numactl package that contains user space tools for page migration via libnuma.

* | [PATCH] page migration: fail if page is in a vma flagged VM_LOCKEDChristoph Lameter2006-03-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | page migration currently simply retries a couple of times if try_to_unmap() fails without inspecting the return code. However, SWAP_FAIL indicates that the page is in a vma that has the VM_LOCKED flag set (if ignore_refs ==1). We can check for that return code and avoid retrying the migration. migrate_page_remove_references() now needs to return a reason why the failure occured. So switch migrate_page_remove_references to use -Exx style error messages.
