* net/fec: carrier off initially to avoid root mount failureOskar Schirmer2010-10-101-0/+3
| | | | | | | | | | | | | | | | with hardware slow in negotiation, the system did freeze while trying to mount root on nfs at boot time. the link state has not been initialised so network stack tried to start transmission right away. this caused instant retries, as the driver solely stated business upon link down, rendering the system unusable. notify carrier off initially to prevent transmission until phylib will report link up.

* net: clear heap allocation for ETHTOOL_GRXCLSRLALLKees Cook2010-10-081-1/+1
| | | | | | | | | | | Calling ETHTOOL_GRXCLSRLALL with a large rule_cnt will allocate kernel heap without clearing it. For the one driver (niu) that implements it, it will leave the unused portion of heap unchanged and copy the full contents back to userspace.

| * mac80211: delete AddBA response timerJohannes Berg2010-10-061-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We never delete the addBA response timer, which is typically fine, but if the station it belongs to is deleted very quickly after starting the BA session, before the peer had a chance to reply, the timer may fire after the station struct has been freed already. Therefore, we need to delete the timer in a suitable spot -- best when the session is being stopped (which will happen even then) in which case the delete will be a no-op most of the time. I've reproduced the scenario and tested the fix.

* | isdn: strcpy() => strlcpy()Dan Carpenter2010-10-081-4/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | setup.phone and setup.eazmsn are 32 character buffers. rcvmsg.msg_data.byte_array is a 48 character buffer. sc_adapter[card]->channel[rcvmsg.phy_link_no - 1].dn is 50 chars. The rcvmsg struct comes from the memcpy_fromio() in receivemessage(). I guess that means it's data off the wire. I'm not very familiar with this code but I don't see any reason to assume these strings are NULL terminated. Also it's weird that "dn" in a 50 character buffer but we only seem to use 32 characters. In drivers/isdn/sc/scioc.h, "dn" is only a 49 character buffer. So potentially there is still an issue there. The important thing for now is to prevent the memory corruption.

| | | | | | | | | | | | | | | | | | | | | | | | | | | L2CAP doesn't permit change like MTU, FCS, TxWindow values while the connection is alive, we can only set that before the connection/configuration process.

| * | Bluetooth: Fix deadlock in the ERTM logicGustavo F. Padovan2010-09-301-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Enhanced Retransmission Mode(ERTM) is a realiable mode of operation of the Bluetooth L2CAP layer. Think on it like a simplified version of TCP. The problem we were facing here was a deadlock. ERTM uses a backlog queue to queue incomimg packets while the user is helding the lock. At some moment the sk_sndbuf can be exceeded and we can't alloc new skbs then the code sleep with the lock to wait for memory, that stalls the ERTM connection once we can't read the acknowledgements packets in the backlog queue to free memory and make the allocation of outcoming skb successful. This patch actually affect all users of bt_skb_send_alloc(), i.e., all L2CAP modes and SCO. We are safe against socket states changes or channels deletion while the we are sleeping wait memory. Checking for the sk->sk_err and sk->sk_shutdown make the code safe, since any action that can leave the socket or the channel in a not usable state set one of the struct members at least. Then we can check both of them when getting the lock again and return with the proper error if something unexpected happens. Signed-off-by: Gustavo F.

| * | Bluetooth: Fix inconsistent lock state with RFCOMMGustavo F. Padovan2010-09-301-0/+4

That's because interrupts were already disabled by l2cap_conn_start() when rfcomm_sk_state_change() try to lock the spin_lock. As result we may have a inconsistent lock state for l2cap_conn_start() after rfcomm_sk_state_change() calls bh_lock_sock() and disable interrupts as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As we don't have any error control on the Streaming mode, i.e., we don't need to keep a copy of the skb for later resending we don't need to call skb_clone() on it. Then we can go one further here, and dequeue the skb before sending it, that also means we don't need to look to sk->sk_send_head anymore. The patch saves memory and time when sending Streaming mode data, so it is good to mainline. Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>

However, in the syscall table, the new syscall still refers to the old getdents which doesn't work. The problem appeared with a system that uses the eglibc 2.12-r11187 (that utilizes that new syscall) is very confused. The fix has been tested with that eglibc version.

Originally it was introduced to describe a backing device which includes an unplug and congestion function and various bits of readahead information and VM-relevant flags. We're also using for tracking dirty inodes for writeback. To make writeback properly find all inodes we need to only access the per-filesystem backing_device pointed to by the superblock in ->s_bdi inside the writeback code, and not the instances pointeded to by inode->i_mapping->backing_dev which can be overriden by special devices or might not be set at all by some filesystems. Long term we should split out the writeback-relevant bits of struct backing_device_info (which includes more than the current bdi_writeback) and only point to it from the superblock while leaving the traditional backing device as a separate structure that can be overriden by devices. The one exception for now is the block device filesystem which really wants different writeback contexts for it's different (internal) inodes to handle the writeout more efficiently. For now we do this with a hack in fs-writeback.c because we're so late in the cycle, but in the future I plan to replace this with a superblock method that allows for multiple writeback contexts per filesystem.

Therefore we revert "do not notify callers from register_xenstore_notifier" and set xenstored_read at the right time for PV on HVM guests too. In fact in case of PV on HVM guests xenstored is ready only after the platform pci driver has completed the initialization, so do not set xenstored_ready before the call to xenbus_probe(). This patch fixes a shutdown_event watcher registration bug that causes "xm shutdown" not to work properly.
