2009-05-29cxgb3: fix dma mapping regressionDivy Le Ray
Commit 5e68b772e6efd189d6aca76f6872fb75d51ace60 cxgb3: map entire Rx page, feed map+offset to Rx ring. introduced a regression on platforms defining DECLARE_PCI_UNMAP_ADDR() and related macros as no-ops. Rx descriptors are fed with the a page buffer bus address + page chunk offset. The page buffer bus address is set and retrieved through pci_unamp_addr_set(), pci_unmap_addr(). These functions being meaningless on x86 (if CONFIG_DMA_API_DEBUG is not set). The HW ends up with a bogus bus address. This patch saves the page buffer bus address for all plaftorms.

Gianfar interrupt handler uses IEVENT_ERR_MASK to check and handle errors. Babbling RX error (IEVENT_BABR) should be included in IEVENT_ERROR_MASK.

2009-05-25r8169: avoid losing MSI interruptsDavid Dillow
The 8169 chip only generates MSI interrupts when all enabled event sources are quiescent and one or more sources transition to active. If not all of the active events are acknowledged, or a new event becomes active while the existing ones are cleared in the handler, we will not see a new interrupt. The current interrupt handler masks off the Rx and Tx events once the NAPI handler has been scheduled, which opens a race window in which we can get another Rx or Tx event and never ACK'ing it, stopping all activity until the link is reset (ifconfig down/up). Fix this by always ACK'ing all event sources, and loop in the handler until we have all sources quiescent.

2009-05-25netfilter: nf_ct_tcp: fix accepting invalid RST segmentsJozsef Kadlecsik
Robert L Mathews discovered that some clients send evil TCP RST segments, which are accepted by netfilter conntrack but discarded by the destination. Thus the conntrack entry is destroyed but the destination retransmits data until timeout. The same technique, i.e. sending properly crafted RST segments, can easily be used to bypass connlimit/connbytes based restrictions (the sample script written by Robert can be found in the netfilter mailing list archives). The patch below adds a new flag and new field to struct ip_ct_tcp_state so that checking RST segments can be made more strict and thus TCP conntrack can catch the invalid ones: the RST segment is accepted only if its sequence number higher than or equal to the highest ack we seen from the other direction. (The last_ack field cannot be reused because it is used to catch resent packets.) Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu> Signed-off-by: Patrick McHardy <kaber@trash.net>
2009-05-25gianfar: fix BUG under load after introduction of skb recyclingLennert Buytenhek
Since commit 0fd56bb5be6455d0d42241e65aed057244665e5e ("gianfar: Add support for skb recycling"), gianfar puts skbuffs that are in the rx ring back onto the recycle list as-is in case there was a receive error, but this breaks the following invariant: that all skbuffs on the recycle list have skb->data = skb->head + NET_SKB_PAD. The RXBUF_ALIGNMENT realignment done in gfar_new_skb() will be done twice on skbuffs recycled in this way, causing there not to be enough room in the skb anymore to receive a full packet, eventually leading to an skb_over_panic from gfar_clean_rx_ring() -> skb_put(). Resetting the skb->data pointer to skb->head + NET_SKB_PAD before putting the skb back onto the recycle list restores the mentioned invariant, and should fix this issue.

2009-05-22wimax/i2400m: usb: fix device reset on autosuspend while not yet idleInaky Perez-Gonzalez
When the i2400m is connected to a network, the host interface (USB) cannot be suspended. For that to happen, the device has to have negotiated with the basestation to put the link on IDLE state. If the host tries to put the device in standby while it is connected but not idle, the device resets, as the driver should not do that. To avoid triggering that, when the USB susbsytem requires the driver to autosuspend the device, the driver checks if the device is not yet idle. If it is not, the request is rejected (will be retried again later on after the autosuspend timeout). At some point the device will enter idle and the request will succeed (unless of course, there is network traffic, but at that point, there is no idle neither in the link or the host interface).

2009-05-20net: fix rtable leak in net/ipv4/route.cEric Dumazet
Alexander V. Lukyanov found a regression in 2.6.29 and made a complete analysis found in http://bugzilla.kernel.org/show_bug.cgi?id=13339 Quoted here because its a perfect one : begin_of_quotation 2.6.29 patch has introduced flexible route cache rebuilding. Unfortunately the patch has at least one critical flaw, and another problem. rt_intern_hash calculates rthi pointer, which is later used for new entry insertion. The same loop calculates cand pointer which is used to clean the list. If the pointers are the same, rtable leak occurs, as first the cand is removed then the new entry is appended to it. This leak leads to unregister_netdevice problem (usage count > 0). Another problem of the patch is that it tries to insert the entries in certain order, to facilitate counting of entries distinct by all but QoS parameters. Unfortunately, referencing an existing rtable entry moves it to list beginning, to speed up further lookups, so the carefully built order is destroyed. For the first problem the simplest patch it to set rthi=0 when rthi==cand, but it will also destroy the ordering. end_of_quotation Problematic commit is 1080d709fb9d8cd4392f93476ee46a9d6ea05a5b (net: implement emergency route cache rebulds when gc_elasticity is exceeded) Trying to keep dst_entries ordered is too complex and breaks the fact that order should depend on the frequency of use for garbage collection. A possible fix is to make rt_intern_hash() simpler, and only makes rt_check_expire() a litle bit smarter, being able to cope with an arbitrary entries order. The added loop is running on cache hot data, while cpu is prefetching next object, so should be unnoticied. Reported-and-analyzed-by: Alexander V.

2009-05-20iwlwifi: do not cancel delayed work inside spin_lock_irqsaveReinette Chatre
Calling cancel_delayed_work() from inside spin_lock_irqsave, introduces a potential deadlock. As explained by Johannes Berg <johannes@sipsolutions.net> A - lock T - timer phase CPU 1 CPU 2 --------------------------------------------- some place that calls cancel_timer_sync() (which is the | code) lock-irq(A) | "lock-irq"(T) | "unlock"(T) | wait(T) unlock(A) timer softirq "lock"(T) run(T) "unlock"(T) irq handler lock(A) unlock(A) Now all that again, interleaved, leading to deadlock: lock-irq(A) "lock"(T) run(T) IRQ during or maybe before run(T) --> lock(A) "lock-irq"(T) wait(T) We fix this by moving the call to cancel_delayed_work() into workqueue. There are cases where the work may not actually be queued or running at the time we are trying to cancel it, but cancel_delayed_work() is able to deal with this. Also cleanup iwl_set_mode related to this call. This function (iwl_set_mode) is only called when bringing interface up and there will thus not be any scanning done. No need to try to cancel scanning.

2009-05-20wext: verify buffer size for SIOCSIWENCODEEXTJohannes Berg
Another design flaw in wireless extensions (is anybody surprised?) in the way it handles the iw_encode_ext structure: The structure is part of the 'extra' memory but contains the key length explicitly, instead of it just being the length of the extra buffer - size of the struct and using the explicit key length only for the get operation (which only writes it). Therefore, we have this layout: extra: +-------------------------+ | struct iw_encode_ext { | | ... | | u16 key_len; | | u8 key[0]; | | }; | +-------------------------+ | key material | +-------------------------+ Now, all drivers I checked use ext->key_len without checking that both key_len and the struct fit into the extra buffer that has been copied from userspace. This leads to a buffer overrun while reading that buffer, depending on the driver it may be possible to specify arbitrary key_len or it may need to be a proper length for the key algorithm specified. Thankfully, this is only exploitable by root, but root can actually cause a segfault or use kernel memory as a key (which you can even get back with siocgiwencode or siocgiwencodeext from the key buffer). Fix this by verifying that key_len fits into the buffer along with struct iw_encode_ext. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

It is illegal to dereference a skb after a successful ndo_start_xmit() call. We must store skb length in a local variable instead. Bug was introduced in 2.6.27 by commit 0abf77e55a2459aa9905be4b226e4729d5b4f0cb (net_sched: Add accessor function for packet length for qdiscs) Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

2009-05-18tcp: fix MSG_PEEK race checkIlpo Järvinen
Commit 518a09ef11 (tcp: Fix recvmsg MSG_PEEK influence of blocking behavior) lets the loop run longer than the race check did previously expect, so we need to be more careful with this check and consider the work we have been doing. I tried my best to deal with urg hole madness too which happens here: if (!sock_flag(sk, SOCK_URGINLINE)) { ++*seq; ... by using additional offset by one but I certainly have very little interest in testing that part.

2009-05-17mv643xx_eth: fix PPC DMA breakageGabriel Paubert
After 2.6.29, PPC no more admits passing NULL to the dev parameter of the DMA API. The result is a BUG followed by solid lock-up when the mv643xx_eth driver brings an interface up. The following patch makes the driver work on my Pegasos again; it is mostly a search and replace of NULL by mp->dev->dev.parent in dma allocation/freeing/mapping/unmapping functions.

2009-05-17bonding: fix link down handling in 802.3ad modeStephen Hemminger
One of the purposes of bonding is to allow for redundant links, and failover correctly if the cable is pulled. If all the members of a bonded device have no carrier present, the bonded device itself needs to report no carrier present to user space so management tools (like routing daemons) can respond. Bonding in 802.3ad mode does not work correctly for this because it incorrectly chooses a link that is down as a possible aggregator.
