* rpc: keep backchannel xprt as long as server connectionJ. Bruce Fields2011-01-113-11/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | Multiple backchannels can share the same tcp connection; from rfc 5661 section 2.10.3.1: A connection's association with a session is not exclusive. A connection associated with the channel(s) of one session may be simultaneously associated with the channel(s) of other sessions including sessions associated with other client IDs. However, multiple backchannels share a connection, they must all share the same xid stream (hence the same rpc_xprt); the only way we have to match replies with calls at the rpc layer is using the xid. So, keep the rpc_xprt around as long as the connection lasts, in case we're asked to use the connection as a backchannel again. Requests to create new backchannel clients over a given server connection should results in creating new clients that reuse the existing rpc_xprt. But to start, just reject attempts to associate multiple rpc_xprt's with the same underlying bc_xprt. Signed-off-by: J. Bruce Fields <bfields@redhat.com>

| | | | | | | | | Now that we have a list of connections to choose from, we can teach the callback code to just pick a suitable connection and use that, instead of insisting on forever using the connection that the first create_session was sent with.

Fix this by respecting the preferred source address when it is provided for local routes. This bug can be demonstrated as follows: # ifconfig dummy0 192.168.0.1 # ip route show table local | grep local.*dummy0 local 192.168.0.1 dev dummy0 proto kernel scope host src 192.168.0.1 # ip route change table local local 192.168.0.1 dev dummy0 \ proto kernel scope host src 127.0.0.1 # ip route show table local | grep local.*dummy0 local 192.168.0.1 dev dummy0 proto kernel scope host src 127.0.0.1 We now establish a local connection and verify the source IP address selection: # nc -l 192.168.0.1 3128 & # nc 192.168.0.1 3128 & # netstat -ant | grep 192.168.0.1:3128.*EST tcp 0 0 192.168.0.1:3128 192.168.0.1:33228 ESTABLISHED tcp 0 0 192.168.0.1:33228 192.168.0.1:3128 ESTABLISHED Signed-off-by: Joel Sing <jsing@google.com> Signed-off-by: David S.

This seems fine itself, but br_send_bpdu() invokes ebtables LOCAL_OUT. We oops in ebt_basic_match() because it assumes eth_hdr(skb) returns a meaningful result.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 3f5a2a713aad28480d86b0add00c68484b54febc zeroes out the statistics message block (SMB) and coalescing message block (CMB) when adapter ring resources are freed. This is desirable behavior, but, as a side effect, the commit leads to an oops when atl1_set_ringparam() attempts to alter the number of rx or tx elements in the ring buffer (by using ethtool -G, for example). We don't want SMB or CMB to change during this operation. Modify atl1_set_ringparam() to preserve SMB and CMB when changing ring parameters.

This was kluged for 64-bit PowerPC in commit 3e502e6 by adding yet another case to the condition. However, 64-bit MIPS configurations are not detected reliably either. This should be fixed by using CONFIG_ARCH_DMA_ADDR_T_64BIT, but that isn't yet defined everywhere it should be. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: David S.

This is most likely a bug in that version of IOS, since it is fixed in later versions. As a workaround this patch allows a module parameter to be set to disable compressing the protocol ID. See: https://bugzilla.vyatta.com/show_bug.cgi?id=3979 RFC 1990 allows an implementation to formulate MP fragments as if protocol compression had been negotiated. This allows us to always send compressed protocol IDs. But some implementations don't accept MP fragments with compressed protocol IDs. This parameter allows us to interoperate with them. The default value of the configurable parameter is the same as the current behavior: protocol compression is enabled. If protocol compression is disabled we will not send compressed protocol IDs. This is based on an earlier patch by Bob Gilligan (using a sysctl). Module parameter is writable to allow for enabling even if ppp is already loaded for other uses.

This often causes the sysfs 'carrier' attribute to be '1' even though no signal has actually been found. uea_probe usbatm_usb_probe driver->bind (uea_bind) uea_boot kthread_run(uea_kthread) uea_kthread usbatm_atm_init uea_start_reset atm_dev_register UPDATE_ATM_SIGNAL UPDATE_ATM_SIGNAL checks whether the ATM device has been created and if not, will not update the PHY signal state. Because of the race that does not always happen in time, and the PHY signal state remains ATM_PHY_SIG_FOUND even though no signal exists. To fix the race, just create the kthread during initialization, and only after initialization is complete, start the thread that reboots the device and initializes PHY state.

The problem was that a temporary page table mapping was being improperly restored. The PXA3xx resume code creates a temporary mapping of resume_turn_on_mmu to avoid a prefetch abort. The pxa3xx_resume_after_mmu code requires that the r1 register holding the address of this mapping not be modified, however, resume_turn_on_mmu does modify it. It is mostly correct in that r1 receives the base table address, but it may also get other bits in 13:0. This results in pxa3xx_resume_after_mmu restoring the original mapping to the wrong place, corrupting memory and leaving the temporary mapping in place.

The function only checks the ibs capabilities and sets up pci devices (if necessary). It runs only on one cpu but operates with the local APIC and some MSRs, thus it is better to disable preemption.

It also currently prints the error value as a pointer, rather than extracting the error code with PTR_ERR(). Fix that. Add a note to the description of the 'nowatchdog' kernel parameter to associate it with this message.

The .ioctl callback was replaced by .unlocked_ioctl for video nodes, but not for radio nodes. This is now corrected.

The patch that added support for a board with wm8775 broke ivtv boards with this device. As we're too close to release 2.6.37, let's just revert it.
