At least on Renesas R8A7778, EESR.ECI interrupt seems to fire regardless of its mask in EESIPR register. I can 100% reproduce it with the following scenario: target is booted with 'ip=on' option, and so IP-Config opens SoC Ether device but doesn't get a proper reply and then succeeds with on-board SMC chip; then I login and try to bring up the SoC Ether device with 'ifconfig', and I get an ECI interrupt once request_irq() is called by sh_eth_open() (while interrupt mask in EESIPR register is all 0), if that interrupt is accompanied by a pending EESR.FRC (frame receive completion) interrupt, I get kernel oops in sh_eth_rx() because sh_eth_ring_init() hasn't been called yet! The solution I worked out is the following: in sh_eth_interrupt(), mask the interrupt status from EESR register with the interrupt mask from EESIPR register in order not to handle the disabled interrupts -- but forcing EESIPR.M_ECI bit in this mask set because we always need to fully handle EESR.ECI interrupt in sh_eth_error() in order to quench it (as it doesn't get cleared by just writing 1 to the this bit as all the other interrupts). While at it, remove unneeded initializer for 'intr_status' variable and give it *unsigned long* type, matching the type of sh_eth_read()'s result; fix comment. Signed-off-by:

The code handling the absent LINK signal (or the absent PSR register -- which reflects the state of this signal) is quite naive and has probably never really worked. It's probably enough to say that this code is executed only on the LINK change interrupt (sic!) but even if we actually have the signal and choose to ignore it (it might be connected to PHY's link/activity LED output as on the Renesas BOCK-W board), sh_eth_adjust_link() on which this code relies to update 'mdp->link' gets executed later than the LINK change interrupt where it is checked, and so RX/TX never get enabled via ECMR register. So, ignore the LINK changed interrupt iff LINK signal is absent (or just chosen not to be used) or PSR register is absent, and enable/disable RX/TX directly in sh_eth_adjust_link() in this case.

commit 35d48903 (bonding: fix rx_handler locking) added a race in bonding driver, reported by Steven Rostedt who did a very good diagnosis : <quoting Steven> I'm currently debugging a crash in an old 3.0-rt kernel that one of our customers is seeing. The bug happens with a stress test that loads and unloads the bonding module in a loop (I don't know all the details as I'm not the one that is directly interacting with the customer). But the bug looks to be something that may still be present and possibly present in mainline too. It will just be much harder to trigger it in mainline. In -rt, interrupts are threads, and can schedule in and out just like any other thread. Note, mainline now supports interrupt threads so this may be easily reproducible in mainline as well. I don't have the ability to tell the customer to try mainline or other kernels, so my hands are somewhat tied to what I can do. But according to a core dump, I tracked down that the eth irq thread crashed in bond_handle_frame() here: slave = bond_slave_get_rcu(skb->dev); bond = slave->bond; <--- BUG the slave returned was NULL and accessing slave->bond caused a NULL pointer dereference. Looking at the code that unregisters the handler: void netdev_rx_handler_unregister(struct net_device *dev) { ASSERT_RTNL(); RCU_INIT_POINTER(dev->rx_handler, NULL); RCU_INIT_POINTER(dev->rx_handler_data, NULL); } Which is basically: dev->rx_handler = NULL; dev->rx_handler_data = NULL; And looking at __netif_receive_skb() we have: rx_handler = rcu_dereference(skb->dev->rx_handler); if (rx_handler) { if (pt_prev) { ret = deliver_skb(skb, pt_prev, orig_dev); pt_prev = NULL; } switch (rx_handler(&skb)) { My question to all of you is, what stops this interrupt from happening while the bonding module is unloading? What happens if the interrupt triggers and we have this: CPU0 CPU1 ---- ---- rx_handler = skb->dev->rx_handler netdev_rx_handler_unregister() { dev->rx_handler = NULL; dev->rx_handler_data = NULL; rx_handler() bond_handle_frame() { slave = skb->dev->rx_handler; bond = slave->bond; <-- NULL pointer dereference!!! What protection am I missing in the bond release handler that would prevent the above from happening? </quoting Steven> We can fix bug this in two ways. First is adding a test in bond_handle_frame() and others to check if rx_handler_data is NULL. A second way is adding a synchronize_net() in netdev_rx_handler_unregister() to make sure that a rcu protected reader has the guarantee to see a non NULL rx_handler_data. The second way is better as it avoids an extra test in fast path. Reported-by:

WOL is broken because the magic packet status bit is getting set rather than the enable bit. The PMT interrupt is not getting serviced because the PMT interrupt is also enabled on the global interrupt, but not cleared by the global interrupt and the global interrupt is higher priority. This fixes both of these issues to get WOL working. There's still a problem with receive after resume, but at least now we can wake-up. Signed-off-by:

John W. Linville says: ==================== Please excuse this larger-than-I-would-like pull request intended for the 3.9 stream. There are a number of late-breaking fixes, including a revert... Regarding the mac80211 bits, Johannes says: "I have two tracing fixes (one from Vladimir), two fixes for P2P device crashes, a fix for a BSS memory leak/lost update problem and a fix from Ben for a scanning issue in mac80211. It's a little on the large side because one of the P2P device problems required a bit much locking work, but I've run through all the different scenarios (wext/nl80211, p2p-device/station interface, ifdown/rfkill) to verify locking with lockdep." As for the iwlwifi bits, Johannes says: "I have three little fixes to the driver from Emmanuel. One addresses a small bug Ben Hutchings found during the stable review process and two address some warnings in the driver when RF-Kill is asserted." Along with those... Avinash Patil fixes an mwifiex bug cause by failing to process a sleep command due to bad SKB manipulation when going into power saving mode. Colin Ian King avoids a null pointer dereference in iwl4965. Dan Williams officially announces that he has dropped maintainership of the libertas driver. Iestyn C. Elfick adds a work-around to avoid b43 DMA transmision sequence error that would lead to a device reset. Luis R. Rodriguez avoids an ath9k warning by not queueing a work item while going to suspend mode. Rafał Miłecki provides a pair of b43 N-PHY fixes related to RSSI calibration. Finally, I revert "brcmsmac: support 4313iPA" because it has been reported in many places to cause problems with the already supported 4313ePA devices. ==================== Signed-off-by:

Marc Kleine-Budde says: ==================== here's a patch series for net for the v3.9 release cycle. Fengguang Wu found two problems with the sja1000 drivers: A macro in the SH architecture collides with one in the sja1000 driver. I created a minimal patch suited for stable, only changing this particular define. (Once net is merged back to net-next, I'll post a patch to uniformly use a SJA1000_ prefix for the sja100 private defines.) If you prefer, I can squash both patches together. Fengguang further noticed that the peak pcmcia driver will not compile on archs without ioport support.

When calculating "offset" for final RSSI calibration we're using numbers bigger than s8 can hold. We have for example: offset[j] = 232 - poll_results[j]; formula. If poll_results[j] is small enough (it usually is) we treat number's bit as a sign bit. For example 232 - 1 becomes: 0xE8 - 0x1 = 0xE7, which is not 231 but -25. This code was introduced in e0c9a021 and caused stability regression on some cards, for ex. BCM4322. Signed-off-by:

Intermittently, b43 will report "Out of order TX status report on DMA ring". When this happens, the driver must be reset before communication can resume. The cause of the problem is believed to be an error in the closed-source firmware; however, all versions of the firmware are affected. This change uses the observation that the expected status is always 2 less than the observed value, and supplies a fake status report to skip one header/data pair. Not all devices suffer from this problem, but it can occur several times per second under heavy load. As each occurence kills the unmodified driver, this patch makes if possible for the affected devices to function. The patch logs only the first instance of the reset operation to prevent spamming the logs. Tested-by:
