2010-02-16USB: gadget: fix EEM gadget CRC usageBrian Niebuhr1-2/+1
eem_wrap() is sending a sentinel CRC, but it didn't indicate that to the host, it should zero bit 14 (bmCRC) in the EEM packet header, instead of setting it. Also remove a redundant crc calculation in eem_unwrap().

2010-02-16USB: otg Kconfig: let USB_OTG_UTILS select USB_ULPI optionValentin Longchamp1-0/+1
With CONFIG_USB_ULPI=y, CONFIG_USB<=m, CONFIG_PCI=n and CONFIG_USB_OTG_UTILS=n, which is the default used for mx31moboard, the build for all mx3 platforms fails because drivers/usb/otg/ulpi.c where otg_ulpi_create is defined is not compiled. Build error: arch/arm/mach-mx3/built-in.o: In function `mxc_board_init': kzmarm11.c:(.init.text+0x73c): undefined reference to `otg_ulpi_create' kzmarm11.c:(.init.text+0x1020): undefined reference to `otg_ulpi_create' This isn't a strong dependency as drivers/usb/otg/ulpi.c doesn't use functions defined in drivers/usb/otg/otg.o and is only needed to get ulpi.o linked into the kernel image.

2010-02-16USB: usbfs: properly clean up the as structure on error pathsLinus Torvalds1-14/+26
I notice that the processcompl_compat() function seems to be leaking the 'struct async *as' in the error paths. I think that the calling convention is fundamentally buggered. The caller is the one that did the "reap_as()" to get the as thing, the caller should be the one to free it too. Freeing it in the caller also means that it very clearly always gets freed, and avoids the need for any "free in the error case too".

2010-02-16dm mpath: fix stall when requeueing ioKiyoshi Ueda1-4/+17
This patch fixes the problem that system may stall if target's ->map_rq returns DM_MAPIO_REQUEUE in map_request(). E.g. stall happens on 1 CPU box when a dm-mpath device with queue_if_no_path bounces between all-paths-down and paths-up on I/O load. When target's ->map_rq returns DM_MAPIO_REQUEUE, map_request() requeues the request and returns to dm_request_fn(). Then, dm_request_fn() doesn't exit the I/O dispatching loop and continues processing the requeued request again. This map and requeue loop can be done with interrupt disabled, so 1 CPU system can be stalled if this situation happens. For example, commands below can stall my 1 CPU box within 1 minute or so: # dmsetup table mp mp: 0 2097152 multipath 1 queue_if_no_path 0 1 1 service-time 0 1 2 8:144 1 1 # while true; do dd if=/dev/mapper/mp of=/dev/null bs=1M count=100; done & # while true; do \ > dmsetup message mp 0 "fail_path 8:144" \ > dmsetup suspend --noflush mp \ > dmsetup resume mp \ > dmsetup message mp 0 "reinstate_path 8:144" \ > done To fix the problem above, this patch changes dm_request_fn() to exit the I/O dispatching loop once if a request is requeued in map_request().

When suspending a failed mirror, bios are completed by mirror_end_io() and __rh_lookup() in dm_rh_dec() returns NULL where a non-NULL return value is required by design. Fix this by not changing the state of the recovery failed region from DM_RH_RECOVERING to DM_RH_NOSYNC in dm_rh_recovery_end().

When recovery_complete() is executed between dm_rh_update_states() and dm_writes() in do_mirror(), bios are processed with the region state, DM_RH_NOSYNC. However, the region data is freed without checking its pending count when dm_rh_update_states() is called next time. When bios are finished by mirror_end_io(), __rh_lookup() in dm_rh_dec() returns NULL even though a valid return value are expected. Solution Remove the state change of the recovery failed region from DM_RH_RECOVERING to DM_RH_NOSYNC in dm_rh_recovery_end(). We can remove the state change because: - If the region data has been released by dm_rh_update_states(), a new region data is created with the state of DM_RH_NOSYNC, and bios are processed according to the DM_RH_NOSYNC state. - If the region data has not been released by dm_rh_update_states(), a state of the region is DM_RH_RECOVERING and bios are put in the delayed_bio list. The flag change from DM_RH_RECOVERING to DM_RH_NOSYNC in dm_rh_recovery_end() was added in the following commit: dm raid1: handle resync failures author Jonathan Brassow <jbrassow@redhat.com> Thu, 12 Jul 2007 16:29:04 +0000 (17:29 +0100) http://git.kernel.org/linus/f44db678edcc6f4c2779ac43f63f0b9dfa28b724 Signed-off-by: Takahiro Yasui <tyasui@redhat.com> Reviewed-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>

If the mirror log fails when the handle_errors option was not selected and there is no remaining valid mirror leg, writes return success even though they weren't actually written to any device. This patch completes them with EIO instead. This code path is taken: do_writes: bio_list_merge(&ms->failures, &sync); do_failures: if (!get_valid_mirror(ms)) (false) else if (errors_handled(ms)) (false) else bio_endio(bio, 0); The logic in do_failures is based on presuming that the write was already tried: if it succeeded at least on one leg (without handle_errors) it is reported as success.

2010-02-16dm log: userspace fix overhead_size calcuationsJonathan Brassow1-3/+7
This patch fixes two bugs that revolve around the miscalculation and misuse of the variable 'overhead_size'. 'overhead_size' is the size of the various header structures used during communication. The first bug is the use of 'sizeof' with the pointer of a structure instead of the structure itself - resulting in the wrong size being computed. This is then used in a check to see if the payload (data_size) would be to large for the preallocated structure. Since the bug produces a smaller value for the overhead, it was possible for the structure to be breached. (Although the current users of the code do not currently send enough data to trigger this bug.) The second bug is that the 'overhead_size' value is used to compute how much of the preallocated space should be cleared before populating it with fresh data. This should have simply been 'sizeof(struct cn_msg)' not overhead_size. The fact that 'overhead_size' was computed incorrectly made this problem "less bad" - leaving only a pointer's worth of space at the end uncleared. Thus, this bug was never producing a bad result, but still needs to be fixed - especially now that the value is computed correctly.

2010-02-16ACPI: fix High cpu temperature with 2.6.32Arjan van de Ven1-0/+8
Since the rewrite of the CPU idle governor in 2.6.32, two laptops have surfaced where the BIOS advertises a C2 power state, but for some reason this state is not functioning (as verified in both cases by powertop before the patch in .32). The old governor had the accidental behavior that if a non-working state was chosen too many times, it would end up falling back to C1. The new governor works differently and this accidental behavior is no longer there; the result is a high temperature on these two machines. This patch adds these 2 machines to the DMI table for C state anomalies; by just not using C2 both these machines are better off (the TSC can be used instead of the pm timer, giving a performance boost for example).

We passed that interface a stack variable, which is kmemdup'ed and assigned to the device's platform_data pointer. Unfortunately, whatever random garbage is in the stack variable gets coped during the kmemdup, and that leads to broken behavior. Explicitly zero out the structure before passing it to the API.

2010-02-15ixgbe: Fix - Do not allow Rx FC on 82598 at 1G due to errataDon Skidmore1-0/+22
The 82598 has an erratum that receipt of pause frames at 1G could lead to a Tx Hang. To avoid this this patch disables Rx FC while at 1G speed for all 82598 parts.

2010-02-15NFS: Too many GETATTR and ACCESS calls after direct I/OChuck Lever1-0/+3
The cached read and write paths initialize fattr->time_start in their setup procedures. The value of fattr->time_start is propagated to read_cache_jiffies by nfs_update_inode(). Subsequent calls to nfs_attribute_timeout() will then use a good time stamp when computing the attribute cache timeout, and squelch unneeded GETATTR calls. Since the direct I/O paths erroneously leave the inode's fattr->time_start field set to zero, read_cache_jiffies for that inode is set to zero after any direct read or write operation. This triggers an otw GETATTR or ACCESS call to update the file's attribute and access caches properly, even when the NFS READ or WRITE replies have usable post-op attributes. Make sure the direct read and write setup code performs the same fattr initialization as the cached I/O paths to prevent unnecessary GETATTR calls. This was likely introduced by commit 0e574af1 in 2.6.15, which appears to add new nfs_fattr_init() call sites in the cached read and write paths, but not in the equivalent places in fs/nfs/direct.c. A subsequent commit in the same series, 33801147, introduces the fattr->time_start field. Interestingly, the direct write reschedule path already has a call to nfs_fattr_init() in the right place.
