2016-01-25rtlwifi: rtl8821ae: Fix 5G failure when EEPROM is incorrectly encodedLarry Finger
Recently, it has been reported that D-Link DWA-582 cards, which use an RTL8812AE chip are not able to scan for 5G networks. The problems started with kernel 4.2, which is the first version that had commit d10101a60372 ("rtlwifi: rtl8821ae: Fix problem with regulatory information"). With this patch, the driver went from setting a default channel plan to using the value derived from EEPROM. Bug reports at https://bugzilla.kernel.org/show_bug.cgi?id=111031 and https://bugzilla.redhat.com/show_bug.cgi?id=1279653 are examples of this problem. The problem was solved once I learned that the internal country code was resulting in a regulatory set with only 2.4 GHz channels. With the RTL8821AE chips available to me, the country code was such that both 2.4 and 5 GHz channels are allowed. The fix is to allow both bands even when the EEPROM is incorrectly encoded.

2016-01-25rt2x00: fix monitor mode regressionEli Cooper
Since commit df1404650ccb ("mac80211: remove support for IFF_PROMISC") monitor mode for rt2x00 has been made effectively useless because the hardware filter is configured to drop packets whose intended recipient is not the device, regardless of the presence of monitor mode interfaces. This patch fixes this regression by adding explicit monitor mode support, and by configuring the hardware filter accordingly.

2016-01-24pptp: fix illegal memory access caused by multiple bind()sHannes Frederic Sowa
Several times already this has been reported as kasan reports caused by syzkaller and trinity and people always looked at RCU races, but it is much more simple. :) In case we bind a pptp socket multiple times, we simply add it to the callid_sock list but don't remove the old binding. Thus the old socket stays in the bucket with unused call_id indexes and doesn't get cleaned up. This causes various forms of kasan reports which were hard to pinpoint. Simply don't allow multiple binds and correct error handling in pptp_bind. Also keep sk_state bits in place in pptp_connect.

By the time we execute bcmgenet_mii_probe(), the MDIO bus structure has long been allocated and registered. Overirring the PHY interrupt using the MDIO bus structure has no chance to work anymore, because of_mdiobus_register() has call phy_device_create() for use, which copied the MDIO bus address's irq for the PHY into the PHY device "irq" member. Since we do have a proper reference to a PHY device in bcmgenet_mii_probe(), just assign the desired IRQ value here.

2016-01-21net: phy: Fix phy_mac_interrupt()Florian Fainelli
Commit 5ea94e7686a3 ("phy: add phy_mac_interrupt()") to use with PHY_IGNORE_INTERRUPT added a cancel_work_sync() into phy_mac_interrupt() which is allowed to sleep, whereas phy_mac_interrupt() is expected to be callable from interrupt context. Now that we have fixed how the PHY state machine treats PHY_IGNORE_INTERRUPT with respect to state changes, we can just set the new link state, and queue the PHY state machine for execution so it is going to read the new link state. For that to work properly, we need to update phy_change() not to try to invoke any interrupt callbacks if we have configured the PHY device for PHY_IGNORE_INTERRUPT, because that PHY device and its driver are not required to implement those.

Commit 2c7b49212a86 ("phy: fix the use of PHY_IGNORE_INTERRUPT") changed a hunk in phy_state_machine() in the PHY_RUNNING case which was not needed. The change essentially makes the PHY library treat PHY devices with PHY_IGNORE_INTERRUPT to keep polling for the PHY device, even though the intent is not to do it. Fix this by reverting that specific hunk, which makes the PHY state machine wait for state changes, and stay in the PHY_RUNNING state for as long as needed.

2016-01-20net: dp83640: Fix tx timestamp overflow handling.Manfred Rudigier
PHY status frames are not reliable, the PHY may not be able to send them during heavy receive traffic. This overflow condition is signaled by the PHY in the next status frame, but the driver did not make use of it. Instead it always reported wrong tx timestamps to user space after an overflow happened because it assigned newly received tx timestamps to old packets in the queue. This commit fixes this issue by clearing the tx timestamp queue every time an overflow happens, so that no timestamps are delivered for overflow packets. This way time stamping will continue correctly after an overflow.

2016-01-19RDMA/be2net: Remove open and close entry pointsDevesh Sharma
Recently Dough Ledford reported a deadlock happening between ocrdma-load sequence and NetworkManager service issueing "open" on be2net interface. The deadlock happens when any be2net hook (e.g. open/close) is called in parallel to insmod ocrdma.ko. A. be2net is sending administrative open/close event to ocrdma holding device_list_mutex. It does this from ndo_open/ndo_stop hooks of be2net. So sequence of locks is rtnl_lock---> device_list lock B. When new ocrdma roce device gets registered, infiniband stack now takes rtnl_lock in ib_register_device() in GID initialization routines. So sequence of locks in this path is device_list lock ---> rtnl_lock. This improper locking sequence causes deadlock. In order to resolve the above deadlock condition, ocrdma intorduced a patch to stop listening to administrative open/close events generated from be2net driver. It now depends on link-state-change async-event generated from CNA. This change leaves behind dead code which used to generate administrative open/close events. This patch cleans-up all that dead code from be2net.

at803x currently automatically enables the RGMII TX clock delay when the phy interface mode is PHY_INTERFACE_MODE_RGMII_TXID. The same should be done when PHY_INTERFACE_MODE_RGMII_ID is specified. Use a similar logic to enable the RGMII RX clock delay as well. at803x_context_{save,restore} were not touched because these are only used on AR8030 which is a RMII phy (RGMII clock delays are irrelevant).

2016-01-17net/mlx5_core: Fix trimming down IRQ numberDoron Tsur
With several ConnectX-4 cards installed on a server, one may receive irqn > 255 from the kernel API, which we mistakenly trim to 8bit. This causes EQ creation failure with the following stack trace: [<ffffffff812a11f4>] dump_stack+0x48/0x64 [<ffffffff810ace21>] __setup_irq+0x3a1/0x4f0 [<ffffffff810ad7e0>] request_threaded_irq+0x120/0x180 [<ffffffffa0923660>] ? mlx5_eq_int+0x450/0x450 [mlx5_core] [<ffffffffa0922f64>] mlx5_create_map_eq+0x1e4/0x2b0 [mlx5_core] [<ffffffffa091de01>] alloc_comp_eqs+0xb1/0x180 [mlx5_core] [<ffffffffa091ea99>] mlx5_dev_init+0x5e9/0x6e0 [mlx5_core] [<ffffffffa091ec29>] init_one+0x99/0x1c0 [mlx5_core] [<ffffffff812e2afc>] local_pci_probe+0x4c/0xa0 Fixing it by changing of the irqn type from u8 to unsigned int to support values > 255 Fixes: 61d0e73e0a5a ('net/mlx5_core: Use the the real irqn in eq->irqn') Reported-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: Doron Tsur <doront@mellanox.com> Signed-off-by: Matan Barak <matanb@mellanox.com> Signed-off-by: David S.

2016-01-16include/linux/kernel.h: change abs() macro so it uses consistent return typeMichal Nazarewicz
Rewrite abs() so that its return type does not depend on the architecture and no unexpected type conversion happen inside of it. The only conversion is from unsigned to signed type. char is left as a return type but treated as a signed type regradless of it's actual signedness. With the old version, int arguments were promoted to long and depending on architecture a long argument might result in s64 or long return type (which may or may not be the same). This came after some back and forth with Nicolas. The current macro has different return type (for the same input type) depending on architecture which might be midly iritating. An alternative version would promote to int like so: #define abs(x) __abs_choose_expr(x, long long, \ __abs_choose_expr(x, long, \ __builtin_choose_expr( \ sizeof(x) <= sizeof(int), \ ({ int __x = (x); __x<0?-__x:__x; }), \ ((void)0)))) I have no preference but imagine Linus might. :] Nicolas argument against is that promoting to int causes iconsistent behaviour: int main(void) { unsigned short a = 0, b = 1, c = a - b; unsigned short d = abs(a - b); unsigned short e = abs(c); printf("%u %u\n", d, e); // prints: 1 65535 } Then again, no sane person expects consistent behaviour from C integer arithmetic. ;) Note: __builtin_types_compatible_p(unsigned char, char) is always false, and __builtin_types_compatible_p(signed char, char) is also always false.

2016-01-15bna: fix Rx data corruption with VLAN stripping enabled and MTU > 4096Ivan Vecera
The multi-buffer Rx mode implemented in the past introduced a regression that causes a data corruption for received VLAN traffic when VLAN tag stripping is enabled. This mode is supported only be newer chipsets (1860) and is enabled when MTU > 4096. When this mode is enabled Rx queue contains buffers with fixed size 2048 bytes. Any incoming packet larger than 2048 is divided into multiple buffers that are attached as skb frags in polling routine. The driver assumes that all buffers associated with a packet except the last one is fully used (e.g. packet with size 5000 are divided into 3 buffers 2048 + 2048 + 904 bytes) and ignores true size reported in completions. This assumption is usually true but not when VLAN packet is received and VLAN tag stripping is enabled. In this case the first buffer is 2044 bytes long but as the driver always assumes 2048 bytes then 4 extra random bytes are included between the first and the second frag. Additionally the driver sets checksum as correct so the packet is properly processed by the core. The driver needs to check the size of used space in each Rx buffer reported by FW and not blindly use the fixed value.
