|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nikolay Aleksandrov says: ==================== This patch-set fixes mainly bugs on enslave failure and one occasion of a needed locking. The patches are: 1. On enslave failure mc addresses are not flushed from the slave 2. On enslave failure vlans are not cleaned up from the slave 3. On enslave failure the bond's primary and curr_active_slave are not cleaned up (which might result in use of freed memory) 4. On enslave failure netpoll is not disabled which might result in a memory leak 5. In bond_mc_swap() the bond's mc addr list is walked without netif_addr_lock, since it can be called without rtnl, add it v2: patch 01 - fix log message and remove unnecessary code move ==================== Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | slave_disable_netpoll() is not called upon enslave failure which would lead to a memory leak. Call slave_disable_netpoll() after err_detach as that's the first error path after enabling netpoll on that slave. Signed-off-by: Nikolay Aleksandrov <nikolay@redhat.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | On enslave failure primary_slave can point to new_slave which is to be freed, and the same applies to curr_active_slave. So check if this is the case and clean up properly after err_detach because that's the first error code path after they're set.

* irda: small read past the end of array in debug codeDan Carpenter2013-04-19
| | | | | | | | | | | | | | | | | | | | The "reason" can come from skb->data[] and it hasn't been capped so it can be from 0-255 instead of just 0-6. For example in irlmp_state_dtr() the code does: reason = skb->data[3]; ... irlmp_disconnect_indication(self, reason, skb); Also LMREASON has a couple other values which don't have entries in the irlmp_reasons[] array. And 0xff is a valid reason as well which means "unknown". So far as I can see we don't actually care about "reason" except for in the debug code.

Linville says: ==================== A few stragglers hoping for 3.9, somewhat delayed due to my travels... On the mac80211 bits, Johannes says: "Sadly, I have another pull request -- the idle handling fix broke LED handling in some cases." and: "Yet one more! This fixes a fairly important/annoying bug -- when roaming between multiple APs of the same network, the system could get stuck thinking it was connected to the old one while it really wasn't." On top of that... Arend sends a brcmfmac patch that removes advertising a feature that isn't actually fully supported, and a brcmsmac patch that rearranges code to request firmware at IFF_UP to play more nicely with being built into the kernel. Felix gives us a minor ath9k_htc fix to support the newly released open source firmware, and an ath9k_hw initvals fix to improve device stability. Rafał Miłecki provides a fix for an ssb regression that caused a serious performance problem with b43. Zefir Kurtisi offers an ath9k fix to change some kmalloc flags to allow the DFS detector to be called in softirq context. Please let me know if there are problems. If these don't make 3.9, I'll just pull them into wireless-next -- just let me know if you want to do it that way! ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

That leaves inconsistent state: cfg80211 thinks it's connected while mac80211 thinks it's not. Typically this won't last long, as soon as mac80211 reports the new association to cfg80211 the old one goes away. If, however, the new authentication or association doesn't succeed, then cfg80211 will forever think the old one still exists and will refuse attempts to authenticate or associate with the AP it thinks it's connected to. Anders reported that this leads to it taking a very long time to reconnect to a network, or never even succeeding. I tested this with an AP hacked to never respond to auth frames, and one that works, and with just those two the system never recovers because one won't work and cfg80211 thinks it's connected to the other so refuses connections to it. To fix this, simply make mac80211 tell cfg80211 when it is no longer connected to the old AP, while authenticating or associating to a new one.

During the manipulation required to release those resources, it's possible for the UNDI to try and write to memory regions which are no longer accessible, causing the PCI bus to prevent further writes from the chip. This would in turn cause DMAE timeouts later on in the driver, as the driver will be unable to use the chip's DMA engines. This patch prevents the chip from actually writing through the PCI bus in said scenario, thus allowing the release without the unfortunate by-product.

This results in the following scenario: A) Administrator sets VF <n> to VLAN 100 B) Administrator sets VF <x> to VLAN 100 C) Administrator sets VF <n> to VLAN 200 D) The VF <n> driver continues to be able to receive traffic on VLAN 100 because the VLVFB pool enable bit for that VF was left set instead of being cleared as it should be. This fix ensures that the old VLAN filter for VF <n> is first removed and the pool bit enable for VF <n> is cleared so that it no longer receives traffic on VLAN 100.

Second packet is received into the other half of this page 4. Page cannot be reused, so is DMA-unmapped 5. The DMA mapping was non-coherent, so unmap copies or invalidates cache The headers added in step 2 get trashed in step 5.

But if we reallocate the headroom of an SKB this can push the skb->csum_start value outside of it's valid range. This can easily happen when collapsing multiple SKBs from the retransmit queue together. Fix from Thomas Graf. 7) Fix NULL deref in be2net driver due to missing check of __vlan_put_tag() return value, from Ivan Vecera. 8) tun_set_iff() returns zero instead of error code on failure, fix from Wei Yongjun. 9) Like GARP, 802 MRP needs to hold the app->lock when adding MAD events and queueing PDUs. Fix from David Ward. 10) Build fix, MVMDIO needs PHYLIB, from Thomas Petazzoni.. 11) Fix mac80211 static with ipv6 modular build, from Cong Wang. 12) If userland specifies a path cost explicitly, do not override it when the carrier state changes. From Stephen Hemminger. 13) mvnets calculates the TX queue to use incorrectly resulting in garbage pointer derefs and crashes, fix from Willy Tarreau. 14) cdc_mbim does erroneous sizeof(ETH_HLEN). Fix from Bjorn Mork. 15) IP fragmentation can leak a refcount-less route out from an RCU protected section. This results in crashes and all sorts of hard to diagnose behavior.

Commit 64f3b9e203bd068 (net: ip_expire() must revalidate route) fixed the case of timeouts, but not the general problem. Tom Parkin noticed crashes in UDP stack and provided a patch, but further analysis permitted us to pinpoint the root cause. Before queueing a packet into a frag list, we must drop its dst, as this dst has limited lifetime (RCU protected) When/if a packet is finally reassembled, we use the dst of the very last skb, still protected by RCU and valid, as the dst of the reassembled packet. Use same logic in IPv6, as there is no need to hold dst references.

As suggested by Ben Hutchings, let's use skb_get_queue_mapping() to get the proper Tx queue number, and use alloc_etherdev_mqs() instead of alloc_etherdev_mq() to create the queues. Both my Mirabox and my OpenBlocks AX3 used to crash without this patch and don't anymore with it. The issue appeared in 3.8 but became more visible after the fix allowing GSO to be enabled. Original work was done by Dmitri Epshtein and Thomas Petazzoni. I just adapted it to take care of Ben's comments.
