2010-03-20ceph: add missing locking to protect i_snap_realm_item during splitSage Weil
All ci->i_snap_realm_item/realm->inodes_with_caps manipulation should be protected by realm->inodes_with_caps_lock. This bug would have only bit us in a rare race with a realm split (during some snap creations). Signed-off-by: Sage Weil <sage@newdream.net>

2010-03-20netfilter: ctnetlink: fix reliable event delivery if message building failsPablo Neira Ayuso
This patch fixes a bug that allows to lose events when reliable event delivery mode is used, ie. if NETLINK_BROADCAST_SEND_ERROR and NETLINK_RECV_NO_ENOBUFS socket options are set. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-03-20netlink: fix NETLINK_RECV_NO_ENOBUFS in netlink_set_err()Pablo Neira Ayuso
Currently, ENOBUFS errors are reported to the socket via netlink_set_err() even if NETLINK_RECV_NO_ENOBUFS is set. However, that should not happen. This fixes this problem and it changes the prototype of netlink_set_err() to return the number of sockets that have set the NETLINK_RECV_NO_ENOBUFS socket option. This return value is used in the next patch in these bugfix series. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-03-20NET_DMA: free skbs periodicallySteven J. Magnani
Under NET_DMA, data transfer can grind to a halt when userland issues a large read on a socket with a high RCVLOWAT (i.e., 512 KB for both). This appears to be because the NET_DMA design queues up lots of memcpy operations, but doesn't issue or wait for them (and thus free the associated skbs) until it is time for tcp_recvmesg() to return. The socket hangs when its TCP window goes to zero before enough data is available to satisfy the read. Periodically issue asynchronous memcpy operations, and free skbs for ones that have completed, to prevent sockets from going into zero-window mode. Signed-off-by: Steven J.

2010-03-19net: ipmr/ip6mr: fix potential out-of-bounds vif_table accessPatrick McHardy
mfc_parent of cache entries is used to index into the vif_table and is initialised from mfcctl->mfcc_parent. This can take values of to 2^16-1, while the vif_table has only MAXVIFS (32) entries. The same problem affects ip6mr. Refuse invalid values to fix a potential out-of-bounds access. Unlike the other validity checks, this is checked in ipmr_mfc_add() instead of the setsockopt handler since its unused in the delete path and might be uninitialized.

2010-03-19ixgbevf: Fix VF Stats accounting after resetGreg Rose
The counters in the 82599 Virtual Function are not clear on read. They accumulate to the maximum value and then roll over. They are also not cleared when the VF executes a soft reset, so it is possible they are non-zero when the driver loads and starts. This has all been accounted for in the code that keeps the stats up to date but there is one case that is not. When the PF driver is reset the counters in the VF are all reset to zero. This adds an additional accounting overhead into the VF driver when the PF is reset under its feet. This patch adds additional counters that are used by the VF driver to accumulate and save stats after a PF reset has been detected. Prior to this patch displaying the stats in the VF after the PF has reset would show bogus data.

2010-03-19ipv4: check rt_genid in dst_checkTimo Teräs
Xfrm_dst keeps a reference to ipv4 rtable entries on each cached bundle. The only way to renew xfrm_dst when the underlying route has changed, is to implement dst_check for this. This is what ipv6 side does too. The problems started after 87c1e12b5eeb7b30b4b41291bef8e0b41fc3dde9 ("ipsec: Fix bogus bundle flowi") which fixed a bug causing xfrm_dst to not get reused, until that all lookups always generated new xfrm_dst with new route reference and path mtu worked. But after the fix, the old routes started to get reused even after they were expired causing pmtu to break (well it would occationally work if the rtable gc had run recently and marked the route obsolete causing dst_check to get called).

2010-03-19ocfs2: Fix the update of name_offset when removing xattrsTao Ma
When replacing a xattr's value, in some case we wipe its name/value first and then re-add it. The wipe is done by ocfs2_xa_block_wipe_namevalue() when the xattr is in the inode or block. We currently adjust name_offset for all the entries which have (offset < name_offset). This does not adjust the entrie we're replacing. Since we are replacing the entry, we don't adjust the total entry count. When we calculate a new namevalue location, we trust the entries now-wrong offset in ocfs2_xa_get_free_start(). The solution is to also adjust the name_offset for the replaced entry, allowing ocfs2_xa_get_free_start() to calculate the new namevalue location correctly. The following script can trigger a kernel panic easily. echo 'y'|mkfs.ocfs2 --fs-features=local,xattr -b 4K $DEVICE mount -t ocfs2 $DEVICE $MNT_DIR FILE=$MNT_DIR/$RANDOM for((i=0;i<76;i++)) do string_76="a$string_76" done string_78="aa$string_76" string_82="aaaa$string_78" touch $FILE setfattr -n 'user.test1234567890' -v $string_76 $FILE setfattr -n 'user.test1234567890' -v $string_78 $FILE setfattr -n 'user.test1234567890' -v $string_82 $FILE Signed-off-by: Tao Ma <tao.ma@oracle.com> Signed-off-by: Joel Becker <joel.becker@oracle.com>
2010-03-19x86, amd: Restrict usage of c1e_idle()Andreas Herrmann
Currently c1e_idle returns true for all CPUs greater than or equal to family 0xf model 0x40. This covers too many CPUs. Meanwhile a respective erratum for the underlying problem was filed (#400). This patch adds the logic to check whether erratum #400 applies to a given CPU. Especially for CPUs where SMI/HW triggered C1e is not supported, c1e_idle() doesn't need to be used. We can check this by looking at the respective OSVW bit for erratum #400.

2010-03-19PCI: cleanup error return for pcix get and set mmrbc functionsDean Nelson
pcix_get_mmrbc() returns the maximum memory read byte count (mmrbc), if successful, or an appropriate error value, if not. Distinguishing errors from correct values and understanding the meaning of an error can be somewhat confusing in that: correct values: 512, 1024, 2048, 4096 errors: -EINVAL -22 PCIBIOS_FUNC_NOT_SUPPORTED 0x81 PCIBIOS_BAD_VENDOR_ID 0x83 PCIBIOS_DEVICE_NOT_FOUND 0x86 PCIBIOS_BAD_REGISTER_NUMBER 0x87 PCIBIOS_SET_FAILED 0x88 PCIBIOS_BUFFER_TOO_SMALL 0x89 The PCIBIOS_ errors are returned from the PCI functions generated by the PCI_OP_READ() and PCI_OP_WRITE() macros. In a similar manner, pcix_set_mmrbc() also returns the PCIBIOS_ error values returned from pci_read_config_[word|dword]() and pci_write_config_word(). Following pcix_get_max_mmrbc()'s example, the following patch simply returns -EINVAL for all PCIBIOS_ errors encountered by pcix_get_mmrbc(), and -EINVAL or -EIO for those encountered by pcix_set_mmrbc(). This simplification was chosen in light of the fact that none of the current callers of these functions are interested in the specific type of error encountered. In the future, should this change, one could simply create a function that maps each PCIBIOS_ error to a corresponding unique errno value, which could be called by pcix_get_max_mmrbc(), pcix_get_mmrbc(), and pcix_set_mmrbc(). Additionally, this patch eliminates some unnecessary variables. Cc: stable@kernel.org Signed-off-by: Dean Nelson <dnelson@redhat.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
2010-03-19PCI: fix access of PCI_X_CMD by pcix get and set mmrbc functionsDean Nelson
An e1000 driver on a system with a PCI-X bus was always being returned a value of 135 from both pcix_get_mmrbc() and pcix_set_mmrbc(). This value reflects an error return of PCIBIOS_BAD_REGISTER_NUMBER from pci_bus_read_config_dword(,, cap + PCI_X_CMD,). This is because for a dword, the following portion of the PCI_OP_READ() macro: if (PCI_##size##_BAD) return PCIBIOS_BAD_REGISTER_NUMBER; expands to: if (pos & 3) return PCIBIOS_BAD_REGISTER_NUMBER; And is always true for 'cap + PCI_X_CMD', which is 0xe4 + 2 = 0xe6. ('cap' is the result of calling pci_find_capability(, PCI_CAP_ID_PCIX).) The same problem exists for pci_bus_write_config_dword(,, cap + PCI_X_CMD,). In both cases, instead of calling _dword(), _word() should be called. Cc: stable@kernel.org Signed-off-by: Dean Nelson <dnelson@redhat.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

2010-03-19PCI: fix return value from pcix_get_max_mmrbc()Dean Nelson
For the PCI_X_STATUS register, pcix_get_max_mmrbc() is returning an incorrect value, which is based on: (stat & PCI_X_STATUS_MAX_READ) >> 12 Valid return values are 512, 1024, 2048, 4096, which correspond to a 'stat' (masked and right shifted by 21) of 0, 1, 2, 3, respectively. A right shift by 11 would generate the correct return value when 'stat' (masked and right shifted by 21) has a value of 1 or 2. But for a value of 0 or 3 it's not possible to generate the correct return value by only right shifting. Fix is based on pcix_get_mmrbc()'s similar dealings with the PCI_X_CMD register.

USB 3 and Wireless USB specify a logarithmic encoding of the endpoint interval that matches the USB 2 specification. usb_fill_int_urb() didn't know that and was filling in the interval as if it was USB 1.1. Fix usb_fill_int_urb() for SuperSpeed devices, but leave the wireless case alone, because David Vrabel wants to keep the old encoding. Update the struct urb kernel doc to note that SuperSpeed URBs must have urb->interval specified in microframes. Add a missing break statement in the usb_submit_urb() interrupt URB checking, since wireless USB and SuperSpeed USB encode urb->interval differently.
