2010-12-08orinoco: clear countermeasure setting on commitDavid Kilroy
... and interface up. In these situations, you are usually trying to connect to a new AP, so keeping TKIP countermeasures active is confusing. This is already how the driver behaves (inadvertently). However, querying SIOCGIWAUTH may tell userspace that countermeasures are active when they aren't. Clear the setting so that the reporting matches what the driver has done..

To avoid copying the skb unnecessarily move the skb_copy call below the checks that don't need write access to the skb. Also, move the assignment of nh_pos and h_pos below the skb_copy to point to the correct skb. It would be possible to avoid another resize of the copied skb by using skb_copy_expand instead of skb_copy but that would make the patch more complex. Also, shared skbs are a corner case right now, so the resize shouldn't matter much.

2010-12-08amd64_edac: Fix interleaving checkBorislav Petkov
When matching error address to the range contained by one memory node, we're in valid range when node interleaving 1. is disabled, or 2. enabled and when the address bits we interleave on match the interleave selector on this node (see the "Node Interleaving" section in the BKDG for an enlightening example).

2010-12-08EDAC: Fix workqueue-related crashesBorislav Petkov
00740c58541b6087d78418cebca1fcb86dc6077d changed edac_core to un-/register a workqueue item only if a lowlevel driver supplies a polling routine. Normally, when we remove a polling low-level driver, we go and cancel all the queued work. However, the workqueue unreg happens based on the ->op_state setting, and edac_mc_del_mc() sets this to OP_OFFLINE _before_ we cancel the work item, leading to NULL ptr oops on the workqueue list. Fix it by putting the unreg stuff in proper order.

2010-12-08nfsd: Fix possible BUG_ON firing in set_change_infoNeil Brown
If vfs_getattr in fill_post_wcc returns an error, we don't set fh_post_change. For NFSv4, this can result in set_change_info triggering a BUG_ON. i.e. fh_post_saved being zero isn't really a bug. So: - instead of BUGging when fh_post_saved is zero, just clear ->atomic. - if vfs_getattr fails in fill_post_wcc, take a copy of i_ctime anyway. This will be used i seg_change_info, but not overly trusted. - While we are there, remove the pointless 'if' statements in set_change_info. There is no harm setting all the values.

2010-12-08ALSA: hda - Reset sample sizes and max bitrates when reading ELDAnssi Hannula
When a new HDMI/DP device is plugged in, hdmi_update_short_audio_desc() is called for every SAD (Short Audio Descriptor) in the ELD data. For LPCM coding type SAD defines the supported sample sizes. For several other coding types (such as AC-3), a maximum bitrate is defined. The maximum bitrate and sample size fields are not always cleared. Therefore, if a device is unplugged and a different one is plugged in, and the coding types of some SAD positions differ between the devices, the old max_bitrate or sample_bits values will persist if the new SADs do not define those values. The leftover max_bitrate and sample_bits do not cause any issues other than wrongly showing up in eld#X.Y procfs file and kernel log. Fix that by always clearing sample_bits and max_bitrate when reading SADs. Signed-off-by: Anssi Hannula <anssi.hannula@iki.fi> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2010-12-07nfs: remove extraneous and problematic calls to nfs_clear_requestTrond Myklebust
When a nfs_page is freed, nfs_free_request is called which also calls nfs_clear_request to clean out the lock and open contexts and free the pagecache page. However, a couple of places in the nfs code call nfs_clear_request themselves. What happens here if the refcount on the request is still high? We'll be releasing contexts and freeing pointers while the request is possibly still in use. Remove those bare calls to nfs_clear_context. That should only be done when the request is being freed. Note that when doing this, we need to watch out for tests of req->wb_page. Previously, nfs_set_page_tag_locked() and nfs_clear_page_tag_locked() would check the value of req->wb_page to figure out if the page is mapped into the nfsi->nfs_page_tree. We now indicate the page is mapped using the new bit PG_MAPPED in req->wb_flags . Reported-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2010-12-07sunrpc: prevent use-after-free on clearing XPT_BUSYNeilBrown
When an xprt is created, it has a refcount of 1, and XPT_BUSY is set. The refcount is *not* owned by the thread that created the xprt (as is clear from the fact that creators never put the reference). Rather, it is owned by the absence of XPT_DEAD. Once XPT_DEAD is set, (And XPT_BUSY is clear) that initial reference is dropped and the xprt can be freed. So when a creator clears XPT_BUSY it is dropping its only reference and so must not touch the xprt again. However svc_recv, after calling ->xpo_accept (and so getting an XPT_BUSY reference on a new xprt), calls svc_xprt_recieved. This clears XPT_BUSY and then svc_xprt_enqueue - this last without owning a reference. This is dangerous and has been seen to leave svc_xprt_enqueue working with an xprt containing garbage. So we need to hold an extra counted reference over that call to svc_xprt_received. For safety, any time we clear XPT_BUSY and then use the xprt again, we first get a reference, and the put it again afterwards. Note that svc_close_all does not need this extra protection as there are no threads running, and the final free can only be called asynchronously from such a thread.

2010-12-08ARM: S3C24XX: Fix mess with gpio {set,get}_pull callbacksVasily Khoruzhick
Currently the {set,get}_pull callbacks of the s3c24xx_gpiocfg_default structure are initalized via s3c_gpio_{get,set}pull_1up. This results in a linker error when only CONFIG_CPU_S3C2442 is selected: arch/arm/plat-s3c24xx/built-in.o:(.data+0x13f4): undefined reference to `s3c_gpio_getpull_1up' arch/arm/plat-s3c24xx/built-in.o:(.data+0x13f8): undefined reference to `s3c_gpio_setpull_1up' The s3c2442 has pulldowns instead of pullups compared to the s3c2440. The method of controlling them is the same though. So this patch modifies the existing s3c_gpio_{get,set}pull_1up helper functions to take an additional parameter deciding whether the pin has a pullup or pulldown. The s3c_gpio_{get,set}pull_1{down,up} functions then wrap that functions passing either S3C_GPIO_PULL_UP or S3C_GPIO_PULL_DOWN. Furthermore this patch sets up the s3c24xx_gpiocfg_default.{get,set}_pull fields in the s3c244{0,2}_map_io function to the new pulldown helper functions.

2010-12-07nfs: kernel should return EPROTONOSUPPORT when not support NFSv4Mi Jinlong
When nfs client(kernel) don't support NFSv4, maybe user build kernel without NFSv4, there is a problem. Using command "mount SERVER-IP:/nfsv3 /mnt/" to mount NFSv3 filesystem, mount should should success, but fail and get error: "mount.nfs: an incorrect mount option was specified" System call mount "nfs"(not "nfs4") with "vers=4", if CONFIG_NFS_V4 is not defined, the "vers=4" will be parsed as invalid argument and kernel return EINVAL to nfs-utils. About that, we really want get EPROTONOSUPPORT rather than EINVAL. This path make sure kernel parses argument success, and return EPROTONOSUPPORT at nfs_validate_mount_data().

2010-12-07NFS: Fix fcntl F_GETLK not reporting some conflictsSergey Vlasov
The commit 129a84de2347002f09721cda3155ccfd19fade40 (locks: fix F_GETLK regression (failure to find conflicts)) fixed the posix_test_lock() function by itself, however, its usage in NFS changed by the commit 9d6a8c5c213e34c475e72b245a8eb709258e968c (locks: give posix_test_lock same interface as ->lock) remained broken - subsequent NFS-specific locking code received F_UNLCK instead of the user-specified lock type. To fix the problem, fl->fl_type needs to be saved before the posix_test_lock() call and restored if no local conflicts were reported.
