Currently e100 uses pci_enable_wake() to clear pending wake-up events and disable PME# during intitialization, but that function is not suitable for this purpose, because it immediately returns error code if device_may_wakeup() returns false for given device. Make e100 use pci_pme_active(), which carries out exactly the required operations, instead. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

The bnx2 driver stores/uses the irq value from the pci_dev internally. But when it stores the irq value, it has been performing an integer demotion. Because of the recent changes made to arch/x86/kernel/io_apic.c, the new method in creating the irq value (using build_irq_for_pci_dev()) has exposed this bug on x86 systems. Because of this demotion when calling request_irq() from bnx2_request_irq(), the driver would get a return code of -EINVAL. This is because the kernel could not find the requested irq descriptor. By storing the irq value properly, the kernel can find the correct irq descriptor and the bnx2 driver can operate normally.

If INIT-ACK is received with SupportedExtensions parameter which indicates that the peer does not support AUTH, the packet will be silently ignore, and sctp_process_init() do cleanup all of the transports in the association. When T1-Init timer is expires, OOPS happen while we try to choose a different init transport. The solution is to only clean up the non-active transports, i.e the ones that the peer added. However, that introduces a problem with sctp_connectx(), because we don't mark the proper state for the transports provided by the user. So, we'll simply mark user-provided transports as ACTIVE. That will allow INIT retransmissions to work properly in the sctp_connectx() context and prevent the crash. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: David S.

The previous patch in response to the recursive locking on IPsec reception is broken as it tries to drop the BH socket lock while in user context. This patch fixes it by shrinking the section protected by the socket lock to sock_queue_rcv_skb only. The only reason we added the lock is for the accounting which happens in that function.

This patch adds a cast in front of the sizeof so that GCC will make a signed comparison and fix the illegal memory dereference. With the patch applied, there is no kmemcheck report.

To speed up the Simple Pairing connection setup, the support for the default link policy has been enabled. This is in contrast to settings the link policy on every connection setup. Using the default link policy is the preferred way since there is no need to dynamically change it for every connection. For backward compatibility reason and to support old userspace the HCISETLINKPOL ioctl has been switched over to using hci_request() to issue the HCI command for setting the default link policy instead of just storing it in the HCI device structure. However the hci_request() can only be issued when the device is brought up. If used on a device that is registered, but still down it will timeout and fail. This is problematic since the command is put on the TX queue and the Bluetooth core tries to submit it to hardware that is not ready yet. The timeout for these requests is 10 seconds and this causes a significant regression when setting up a new device. The userspace can perfectly handle a failure of the HCISETLINKPOL ioctl and will re-submit it later, but the 10 seconds delay causes a problem. So in case hci_request() is called on a device that is still down, just fail it with ENETDOWN to indicate what happens. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

Use TX control flag IEEE80211_TX_CTL_ASSIGN_SEQ as a request to update the seq# for the frames. This will likely require some further cleanup to get seq# correctly for Beacons vs. other frames and also potentially for multiple BSSes. Anyway, this is better than ending up sending out most frames with seq# 0. (This is a backport of patch w/ same title already in net-next-2.6. It is verified to fix http://bugzilla.kernel.org/show_bug.cgi?id=11394 and it should be acceptable for -rc due to the driver being new in 2.6.27.)

The Security Mode 4 of the Bluetooth 2.1 specification has strict authentication and encryption requirements. It is the initiators job to create a secure ACL link. However in case of malicious devices, the acceptor has to make sure that the ACL is encrypted before allowing any kind of L2CAP connection. The only exception here is the PSM 1 for the service discovery protocol, because that is allowed to run on an insecure ACL link. Previously it was enough to reject a L2CAP connection during the connection setup phase, but with Bluetooth 2.1 it is forbidden to do any L2CAP protocol exchange on an insecure link (except SDP). The new hci_conn_check_link_mode() function can be used to check the integrity of an ACL link. This functions also takes care of the cases where Security Mode 4 is disabled or one of the devices is based on an older specification. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

With the introduction of Security Mode 4 and Simple Pairing from the Bluetooth 2.1 specification it became mandatory that the initiator requires authentication and encryption before any L2CAP channel can be established. The only exception here is PSM 1 for the service discovery protocol (SDP). It is meant to be used without any encryption since it contains only public information. This is how Bluetooth 2.0 and before handle connections on PSM 1. For Bluetooth 2.1 devices the pairing procedure differentiates between no bonding, general bonding and dedicated bonding. The L2CAP layer wrongly uses always general bonding when creating new connections, but it should not do this for SDP connections. In this case the authentication requirement should be no bonding and the just-works model should be used, but in case of non-SDP connection it is required to use general bonding. If the new connection requires man-in-the-middle (MITM) protection, it also first wrongly creates an unauthenticated link key and then later on requests an upgrade to an authenticated link key to provide full MITM protection. With Simple Pairing the link key generation is an expensive operation (compared to Bluetooth 2.0 and before) and doing this twice during a connection setup causes a noticeable delay when establishing a new connection. This should be avoided to not regress from the expected Bluetooth 2.0 connection times. The authentication requirements are known up-front and so enforce them. To fulfill these requirements the hci_connect() function has been extended with an authentication requirement parameter that will be stored inside the connection information and can be retrieved by userspace at any time. This allows the correct IO capabilities exchange and results in the expected behavior. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

The ACL config stage keeps holding a reference count on incoming connections when requesting the extended features. This results in keeping an ACL link up without any users. The problem here is that the Bluetooth specification doesn't define an ownership of the ACL link and thus it can happen that the implementation on the initiator side doesn't care about disconnecting unused links. In this case the acceptor needs to take care of this. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

Automounter maps can contain mount options valid for other NFS implementations but not for Linux. The Linux automounter uses the mount command's "-s" command line option ("s" for "sloppy") so that mount requests containing such options are not rejected. Commit f45663ce attempted to address a known regression with text-based NFS mount option parsing. Unrecognized mount options would cause mount requests to fail, even if the "-s" option was used on the mount command line. Unfortunately, this commit was not complete as submitted. It adds a new mount option, "sloppy". But it is missing a hunk, so it now allows NFS mounts with unrecognized mount options, even if the "sloppy" option is not present. This could be a problem if a required critical mount option such as "sync" is misspelled, for example, and is considered a regression from 2.6.26. This patch restores the missing hunk. Now, the default behavior of text-based NFS mount options is as before: any unrecognized mount option will cause the mount to fail. Please include this in 2.6.27-rc.

He then correlated this with a report by bdupree@techfinesse.com: http://marc.info/?l=linux-kernel&m=119613299024398&w=2 and the culprit cause seems to be starting the bridge interface. In particular, when starting the bridge interface, his scripts are specifying a hello timer interval of "0". The bridge hello time can't be safely set to values less than 1 second, otherwise it is possible to end up with a runaway timer.

The timewait sockets life cycle is not tied with the network namespace, that means the timewait sockets stay alive while the network namespace dies. The timewait sockets are for avoiding to receive a duplicate packet from the network, if the network namespace is freed, the network stack is removed, so no chance to receive any packets from the outside world. Furthermore, having a pending destruction timer on these sockets with a network namespace freed is not safe and will lead to an oops if the timer callback which try to access data belonging to the namespace like for example in: inet_twdr_do_twkill_work -> NET_INC_STATS_BH(twsk_net(tw), LINUX_MIB_TIMEWAITED); Purging the timewait sockets at the network namespace destruction will: 1) speed up memory freeing for the namespace 2) fix kernel panic on asynchronous timewait destruction Signed-off-by: Daniel Lezcano <dlezcano@fr.ibm.com> Acked-by: Denis V.

PHY events may trigger HSM_ST_ERR with other error codes and, with or without it, there just isn't much reason to do WARN_ON() on it. Even if error code is not set there, core EH logic won't have any problem dealing with the error condition. OSDL bz#11065 reports this problem.

of them being unifying probing, hotplug and EH reset paths uniform. Previously, broken hardreset could go unnoticed as it wasn't used during probing but when something goes wrong or after hotplug the problem will surface and bite hard. OSDL bug 11195 reports that sata_nv generic flavor falls into this category. Hardreset itself succeeds but PHY stays offline after hardreset. I tried longer debounce timing but the result was the same. http://bugzilla.kernel.org/show_bug.cgi?id=11195 So, it seems we'll have to drop hardreset from the generic flavor.

I've been chasing Jeff about this for months. Jeff added the Marvell device identifiers to the ahci driver without making the AHCI driver handle the PATA port. This means a lot of users can't use current kernels and in most distro cases can't even install. This has been going on since March 2008 for the 6121 Marvell, and late 2007 for the 6145!!! This was all pointed out at the time and repeatedly ignored. Bugs assigned to Jeff about this are ignored also. To quote Jeff in email > "Just switch the order of 'ahci' and 'pata_marvell' in > /etc/modprobe.conf, then use Fedora's tools regenerate the initrd. > See? It's not rocket science, and the current configuration can be > easily made to work for Fedora users." (Which isn't trivial, isn't end user, shouldn't be needed, and as it usually breaks at install time is in fact impossible) To quote Jeff in August 2007 > " mv-ahci-pata > Marvell 6121/6141 PATA support. Needs fixing in the 'PATA controller > command' area before it is usable, and can go upstream." Only he add the ids anyway later and caused regressions, adding a further id in March causing more regresions. The actual fix for the moment is very simple. If the user has included the pata_marvell driver let it drive the ports. If they've only selected for SATA support give them the AHCI driver which will run the port a fraction faster. Allow the user to control this decision via ahci.marvell_enable as a module parameter so that distributions can ship 'it works' defaults and smarter users (or config tools) can then flip it over it desired.

A make -j20 powerpc kernel build broke a couple of months ago saying: In file included from arch/powerpc/boot/gunzip_util.h:13, from arch/powerpc/boot/prpmc2800.c:21: arch/powerpc/boot/zlib.h:85: error: expected ‘:’, ‘,’, ‘;’, ‘}’ or ‘__attribute__’ before ‘*’ token arch/powerpc/boot/zlib.h:630: warning: type defaults to ‘int’ in declaration of ‘Byte’ arch/powerpc/boot/zlib.h:630: error: expected ‘;’, ‘,’ or ‘)’ before ‘*’ token It happened again yesterday: too rare for me to confirm the fix, but it looks like the list of dependants on gunzip_util.h was incomplete.
