2010-12-09md: protect against NULL reference when waiting to start a raid10.NeilBrown2-4/+3
When we fail to start a raid10 for some reason, we call md_unregister_thread to kill the thread that was created. Unfortunately md_thread() will then make one call into the handler (raid10d) even though md_wakeup_thread has not been called. This is not safe and as md_unregister_thread is called after mddev->private has been set to NULL, it will definitely cause a NULL dereference. So fix this at both ends: - md_thread should only call the handler if THREAD_WAKEUP has been set. - raid10 should call md_unregister_thread before setting things to NULL just like all the other raid modules do. This is applicable to 2.6.35 and later. Cc: [email protected] Reported-by: "Citizen" <[email protected]> Signed-off-by: NeilBrown <[email protected]>
2010-12-09md: fix bug with re-adding of partially recovered device.NeilBrown1-2/+5
With v0.90 metadata, a hot-spare does not become a full member of the array until recovery is complete. So if we re-add such a device to the array, we know that all of it is as up-to-date as the event count would suggest, and so it a bitmap-based recovery is possible. However with v1.x metadata, the hot-spare immediately becomes a full member of the array, but it record how much of the device has been recovered. If the array is stopped and re-assembled recovery starts from this point. When such a device is hot-added to an array we currently lose the 'how much is recovered' information and incorrectly included it as a full in-sync member (after bitmap-based fixup). This is wrong and unsafe and could corrupt data. So be more careful about setting saved_raid_disk - which is what guides the re-adding of devices back into an array. The new code matches the code in slot_store which does a similar thing, which is encouraging. This is suitable for any -stable kernel.

2010-12-09md: fix possible deadlock in handling flush requests.NeilBrown1-2/+4
As recorded in https://bugzilla.kernel.org/show_bug.cgi?id=24012 it is possible for a flush request through md to hang. This is due to an interaction between the recursion avoidance in generic_make_request, the insistence in md of only having one flush active at a time, and the possibility of dm (or md) submitting two flush requests to a device from the one generic_make_request. If a generic_make_request call into dm causes two flush requests to be queued (as happens if the dm table has two targets - they get one each), these two will be queued inside generic_make_request. Assume they are for the same md device. The first is processed and causes 1 or more flush requests to be sent to lower devices. These get queued within generic_make_request too. Then the second flush to the md device gets handled and it blocks waiting for the first flush to complete. But it won't complete until the two lower-device requests complete, and they haven't even been submitted yet as they are on the generic_make_request queue. The deadlock can be broken by using a separate thread to submit the requests to lower devices. md has such a thread readily available: md_wq. So use it to submit these requests.

2010-12-08IB/uverbs: Handle large number of entries in poll CQDan Carpenter1-43/+56
In ib_uverbs_poll_cq() code there is a potential integer overflow if userspace passes in a large cmd.ne. The calls to kmalloc() would allocate smaller buffers than intended, leading to memory corruption. There iss also an information leak if resp wasn't all used. Unprivileged userspace may call this function, although only if an RDMA device that uses this function is present. Fix this by copying CQ entries one at a time, which avoids the allocation entirely, and also by moving this copying into a function that makes sure to initialize all memory copied to userspace.

2010-12-08orinoco: fix TKIP countermeasure behaviourDavid Kilroy1-2/+2
Enable the port when disabling countermeasures, and disable it on enabling countermeasures. This bug causes the response of the system to certain attacks to be ineffective. It also prevents wpa_supplicant from getting scan results, as wpa_supplicant disables countermeasures on startup - preventing the hardware from scanning. wpa_supplicant works with ap_mode=2 despite this bug because the commit handler re-enables the port. The log tends to look like: State: DISCONNECTED -> SCANNING Starting AP scan for wildcard SSID Scan requested (ret=0) - scan timeout 5 seconds EAPOL: disable timer tick EAPOL: Supplicant port status: Unauthorized Scan timeout - try to get results Failed to get scan results Failed to get scan results - try scanning again Setting scan request: 1 sec 0 usec Starting AP scan for wildcard SSID Scan requested (ret=-1) - scan timeout 5 seconds Failed to initiate AP scan.

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.

Note: this patch should be sent to stable teams (2.6.34 and up) [PATCH net-2.6] llc: fix a device refcount imbalance commit abf9d537fea225 (llc: add support for SO_BINDTODEVICE) added one refcount imbalance in llc_ui_bind(), because dev_getbyhwaddr() doesnt take a reference on device, while dev_get_by_index() does. Fix this using RCU locking. And since an RCU conversion will be done for 2.6.38 for dev_getbyhwaddr(), put the rcu_read_lock/unlock exactly at their final place.

2010-12-08ifb: goto resched directly if error happens and dp->tq isn't emptyChangli Gao1-0/+2
If we break the loop when there are still skbs in tq and no skb in rq, the skbs will be left in txq until new skbs are enqueued into rq. In rare cases, no new skb is queued, then these skbs will stay in rq forever. After this patch, if tq isn't empty when we break the loop, we goto resched directly.

2010-12-08tcp: Bug fix in initialization of receive window.Nandita Dukkipati1-5/+4
The bug has to do with boundary checks on the initial receive window. If the initial receive window falls between init_cwnd and the receive window specified by the user, the initial window is incorrectly brought down to init_cwnd. The correct behavior is to allow it to remain unchanged. Signed-off-by: Nandita Dukkipati <[email protected]> Signed-off-by: David S. Miller <[email protected]>

Fix the calculation of the inexact hash-based MAC address filter. It's 64 bits but current code is missing a ULL. Results in filtering out some legitimate packets. Signed-off-by: Dimitris Michailidis <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2010-12-08nfsd: Fix possible BUG_ON firing in set_change_infoNeil Brown2-13/+14
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.

2010-12-08KVM: enlarge number of possible CPUID leavesAndre Przywara1-1/+1
Currently the number of CPUID leaves KVM handles is limited to 40. My desktop machine (AthlonII) already has 35 and future CPUs will expand this well beyond the limit.

2010-12-08KVM: SVM: Do not report xsave in supported cpuidJoerg Roedel4-10/+9
To support xsave properly for the guest the SVM module need software support for it. As long as this is not present do not report the xsave as supported feature in cpuid. As a side-effect this patch moves the bit() helper function into the x86.h file so that it can be used in svm.c too. KVM-Stable-Tag.
