This patch proposes to remove the IRQF_DISABLED flag from CRIS architecture code. It's a NOOP since 2.6.35 and it will be removed one day. Comments mentioning IRQF_DISABLED are also updated, knowing that all interrupts are now "fast interrupts", their handlers running with interrupts disabled. Don't hesitate to let me know if you have other ways of rephrasing the comments! This is an update for 3.11 of a patch already sent for 3.10 Signed-off-by: Michael Opdenacker <michael.opdenacker@free-electrons.com> Signed-off-by: Jesper Nilsson <jespern@axis.com>

The only BIOS on record that needs the 14 offset has a bios major version 2 but BMP version 1.01. Another bunch of BIOSes that need the 18 offset have BMP version 2.01 or 5.01 or higher. So instead of looking at the bios major version, look at the BMP version. BIOSes with BMP version 0 do not contain a detectable script, so always return 0 for them.

Jani for co-maintainer! Jani has been a really active bug-scrubber in the past few months. I've asked him whether he wants to do this in a more official capacity and he agreed. I've already chatted with Dave and Jesse and they support this. Note that everyone can't now just relax because "Jani will do all the bug scrubbing" - au contraire expect more nagging and poking now that we have more bandwidth. Longer-term the plan is to share more of the maintainer duties, but we need to fix up the infrastructure a bit first (like moving the git repo to a common location). While at it also add the newly set-up patchwork instance.

br_multicast_set_hash_max() is called from process context in net/bridge/br_sysfs_br.c by the sysfs store_hash_max() function. br_multicast_set_hash_max() calls spin_lock(&br->multicast_lock), which can deadlock the CPU if a softirq that also tries to take the same lock interrupts br_multicast_set_hash_max() while the lock is held . This can happen quite easily when any of the bridge multicast timers expire, which try to take the same lock. The fix here is to use spin_lock_bh(), preventing other softirqs from executing on this CPU. Steps to reproduce: 1. Create a bridge with several interfaces (I used 4). 2. Set the "multicast query interval" to a low number, like 2. 3. Enable the bridge as a multicast querier. 4. Repeatedly set the bridge hash_max parameter via sysfs. # brctl addbr br0 # brctl addif br0 eth1 eth2 eth3 eth4 # brctl setmcqi br0 2 # brctl setmcquerier br0 1 # while true ; do echo 4096 > /sys/class/net/br0/bridge/hash_max; done Signed-off-by: Curt Brune <curt@cumulusnetworks.com> Signed-off-by: Scott Feldman <sfeldma@cumulusnetworks.com> Signed-off-by: David S.

It does not make sense to create an anycast address for an /128-prefix. Suppress it. As 32019e65 ("ipv6: Do not leave router anycast address for /127 prefixes.") shows we also may not leave them, because we could accidentally remove an anycast address the user has allocated or got added via another prefix.

The existing serial state notification handling expected older Option devices, having a hardcoded assumption that the Modem port was always USB interface #2. That isn't true for devices from the past few years. hso_serial_state_notification is a local cache of a USB Communications Interface Class SERIAL_STATE notification from the device, and the USB CDC specification (section 6.3, table 67 "Class-Specific Notifications") defines wIndex as the USB interface the event applies to. For hso devices this will always be the Modem port, as the Modem port is the only port which is set up to receive them by the driver. So instead of always expecting USB interface #2, instead validate the notification with the actual USB interface number of the Modem port. Signed-off-by: Dan Williams <dcbw@redhat.com> Tested-by: H.

Commit f5a44db5 introduced a regression on filesystems created with the bigalloc feature (cluster size > blocksize). It causes xfstests generic/006 and /013 to fail with an unexpected JBD2 failure and transaction abort that leaves the test file system in a read only state. Other xfstests run on bigalloc file systems are likely to fail as well. The cause is the accidental use of a cluster mask where a cluster offset was needed in ext4_ext_map_blocks().

In function lowpan_header_create(), we invoke the following code construct: struct ipv6hdr *hdr; ... hdr = ipv6_hdr(skb); ... if (...) memcpy(hc06_ptr + 1, &hdr->flow_lbl[1], 2); else memcpy(hc06_ptr, &hdr, 4); Where the else path of the condition, that is, non-compression path, calls memcpy() with a pointer to struct ipv6hdr *hdr as source, thus two levels of indirection. This cannot be correct, and likely only one level of pointer was intended as source buffer for memcpy() here.

If the hypervisor configures a vlan for the VF via the PF, the expected result is that only packets tagged by said vlan will be received by the VF (and that vlan will be silently removed). Due to an incorrect manipulation of vlan filters in the driver, the VF can receive untagged traffic even if the hypervisor configured some vlan for it. This patch corrects the behaviour.

There are 2 different (related) flows in the slowpath configuration that utilize the same pointer and cast it to different structs; This is obviously incorrect as the intended allocated memory is that of the smaller struct, possibly causing the flow utilizing the larger struct to corrupt other slowpath configuration.
