2010-08-31ath9k_hw: fix parsing of HT40 5 GHz CTLsLuis R. Rodriguez
The 5 GHz CTL indexes were not being read for all hardware devices due to the masking out through the CTL_MODE_M mask being one bit too short. Without this the calibrated regulatory maximum values were not being picked up when devices operate on 5 GHz in HT40 mode. The final output power used for Atheros devices is the minimum between the calibrated CTL values and what CRDA provides. Cc: stable@kernel.org [2.6.27+] Signed-off-by: Luis R.

The EEPROM is compressed on AR9003, upon decompression the wrong upper limit was being used for the block which prevented the 5 GHz CTL indexes from being used, which are stored towards the end of the EEPROM block.

If irda_open_tsap() fails, the irda_bind() code tries to destroy the ->ias_obj object by hand, but does so wrongly. In particular, it fails to a) release the hashbin attached to the object and b) reset the self->ias_obj pointer to NULL. Fix both problems by using irias_delete_object() and explicitly setting self->ias_obj to NULL, just as irda_release() does. Reported-by: Tavis Ormandy <taviso@cmpxchg8b.com> Signed-off-by: David S.

2010-08-30wireless extensions: fix kernel heap content leakJohannes Berg
Wireless extensions have an unfortunate, undocumented requirement which requires drivers to always fill iwp->length when returning a successful status. When a driver doesn't do this, it leads to a kernel heap content leak when userspace offers a larger buffer than would have been necessary. Arguably, this is a driver bug, as it should, if it returns 0, fill iwp->length, even if it separately indicated that the buffer contents was not valid. However, we can also at least avoid the memory content leak if the driver doesn't do this by setting the iwp length to max_tokens, which then reflects how big the buffer is that the driver may fill, regardless of how big the userspace buffer is. To illustrate the point, this patch also fixes a corresponding cfg80211 bug (since this requirement isn't documented nor was ever pointed out by anyone during code review, I don't trust all drivers nor all cfg80211 handlers to implement it correctly).

The new workqueue changes helped me find this bug that's been lingering since the changes to the work processing in mac80211 -- the work timer is never deleted properly. Do that to avoid having it fire after all data structures have been freed. It can't be re-armed because all it will do, if running, is schedule the work, but that gets flushed later and won't have anything to do since all work items are gone by now (by way of interface removal).

Michael reported that p54* never really entered power save mode, even tough it was enabled. It turned out that upon a power save mode change the firmware will set a special flag onto the last outgoing frame tx status (which in this case is almost always the designated PSM nullfunc frame). This flag confused the driver; It erroneously reported transmission failures to the stack, which then generated the next nullfunc. and so on...

2010-08-27net/ipv4: Eliminate kstrdup memory leakJulia Lawall
The string clone is only used as a temporary copy of the argument val within the while loop, and so it should be freed before leaving the function. The call to strsep, however, modifies clone, so a pointer to the front of the string is kept in saved_clone, to make it possible to free it. The sematic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ local idexpression x; expression E; identifier l; statement S; @@ *x= \(kasprintf\|kstrdup\)(...); ... if (x == NULL) S ... when != kfree(x) when != E = x if (...) { <... when != kfree(x) * goto l; ...> * return ...; } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.

2010-08-25tcp: fix three tcp sysctls tuningEric Dumazet
As discovered by Anton Blanchard, current code to autotune tcp_death_row.sysctl_max_tw_buckets, sysctl_tcp_max_orphans and sysctl_max_syn_backlog makes little sense. The bigger a page is, the less tcp_max_orphans is : 4096 on a 512GB machine in Anton's case. (tcp_hashinfo.bhash_size * sizeof(struct inet_bind_hashbucket)) is much bigger if spinlock debugging is on. Its wrong to select bigger limits in this case (where kernel structures are also bigger) bhash_size max is 65536, and we get this value even for small machines. A better ground is to use size of ehash table, this also makes code shorter and more obvious. Based on a patch from Anton, and another from David.

2010-08-24phylib: Fix race between returning phydev and calling adjust_linkAnton Vorontsov
It is possible that phylib will call adjust_link before returning from {,of_}phy_connect(), which may cause the following [very rare, though] oops upon reopening the device: Unable to handle kernel paging request for data at address 0x0000024c Oops: Kernel access of bad area, sig: 11 [#1] PREEMPT SMP NR_CPUS=2 LTT NESTING LEVEL : 0 P1021 RDB Modules linked in: NIP: c0345dac LR: c0345dac CTR: c0345d84 TASK = dffab6b0[30] 'events/0' THREAD: c0d24000 CPU: 0 [...] NIP [c0345dac] adjust_link+0x28/0x19c LR [c0345dac] adjust_link+0x28/0x19c Call Trace: [c0d25f00] [000045e1] 0x45e1 (unreliable) [c0d25f30] [c036c158] phy_state_machine+0x3ac/0x554 [...] Here is why. Drivers store phydev in their private structures, e.g. gianfar driver: static int init_phy(struct net_device *dev) { ... priv->phydev = of_phy_connect(...); ... } So that adjust_link could retrieve it back: static void adjust_link(struct net_device *dev) { ... struct phy_device *phydev = priv->phydev; ... } If the device has been opened before, then phydev->state is set to PHY_HALTED (or undefined if the driver didn't call phy_stop()). Now, phy_connect starts the PHY state machine before returning phydev to the driver: phy_start_machine(phydev, NULL); if (phydev->irq > 0) phy_start_interrupts(phydev); return phydev; The time between 'phy_start_machine()' and 'return phydev' is undefined. The start machine routine delays execution for 1 second, which is enough for most cases. But under heavy load, or if you're unlucky, it is quite possible that PHY state machine will execute before phy_connect() returns, and so adjust_link callback will try to dereference phydev, which is not yet ready. To fix the issue, simply initialize the PHY's state to PHY_READY during phy_attach(). This will ensure that phylib won't call adjust_link before phy_start().

2010-08-243c59x: Fix deadlock between boomerang_interrupt and boomerang_start_txNeil Horman
If netconsole is in use, there is a possibility for deadlock in 3c59x between boomerang_interrupt and boomerang_start_xmit. Both routines take the vp->lock, and if netconsole is in use, a pr_* call from the boomerang_interrupt routine will result in the netconsole code attempting to trnasmit an skb, which can try to take the same spin lock, resulting in deadlock. The fix is pretty straightforward. This patch allocats a bit in the 3c59x private structure to indicate that its handling an interrupt. If we get into the transmit routine and that bit is set, we can be sure that we have recursed and will deadlock if we continue, so instead we just return NETDEV_TX_BUSY, so the stack requeues the skb to try again later.

2010-08-19e1000e: don't check for alternate MAC addr on parts that don't support itBruce Allan
From: Bruce Allan <bruce.w.allan@intel.com> The alternate MAC address feature is only supported by 80003ES2LAN and 82571 LOMs as well as a couple 82571 mezzanine cards. Checking for an alternate MAC address on other parts can fail leading to the driver not able to load. This patch limits the check for an alternate MAC address to be done only for parts that support the feature. This issue has been around since support for the feature was introduced to the e1000e driver in 2.6.34.

2010-08-19e1000e: disable ASPM L1 on 82573Bruce Allan
On the e1000-devel mailing list, Nils Faerber reported latency issues with the 82573 LOM on a ThinkPad X60. It was found to be caused by ASPM L1; disabling it resolves the latency. The issue is present in kernels back to 2.6.34 and possibly 2.6.33.

2010-08-18ehea: Fix synchronization between HW and SW send queueAndre Detsch
ehea: Fix synchronization between HW and SW send queue When memory is added to / removed from a partition via the Memory DLPAR mechanism, the eHEA driver has to do a couple of things to reflect the memory change in its own IO address translation tables. This involves stopping and restarting the HW queues. During this operation, it is possible that HW and SW pointer into these queues get out of sync. This results in a situation where packets that are attached to a send queue are not transmitted immediately, but delayed until further X packets have been put on the queue. This patch detects such loss of synchronization, and resets the ehea port when needed.
