* kernel: fix refcnt leak in LED netdev trigger on interface renameRafał Miłecki2019-03-061-17/+13
| | | | | | | | | | | | | | | | | | | | | | | | | Renaming a netdev-trigger-tracked interface was resulting in an unbalanced dev_hold(). Example: > iw phy phy0 interface add foo type __ap > echo netdev > trigger > echo foo > device_name > ip link set foo name bar > iw dev bar del [ 237.355366] unregister_netdevice: waiting for bar to become free. Usage count = 1 [ 247.435362] unregister_netdevice: waiting for bar to become free. Usage count = 1 [ 257.545366] unregister_netdevice: waiting for bar to become free. Usage count = 1 Above problem was caused by trigger checking a dev->name which obviously changes after renaming an interface. It meant missing all further events including the NETDEV_UNREGISTER which is required for calling dev_put(). This change fixes that by: 1) Comparing device struct *address* for notification-filtering purposes 2) Dropping unneeded NETDEV_CHANGENAME code (no behavior change) Signed-off-by: Rafał Miłecki <rafal@milecki.pl>
* generic: revert workarounds for AR8337 switchMathias Kresin2018-08-232-62/+1
| | | | | | | | | | | | | The intention of 967b6be118e3 ("ar8327: Add workarounds for AR8337 switch") was to remove the register fixups for AR8337. But instead they were removed for AR8327. The RGMII RX delay is forced even if the port is used as phy instead of mac, which results in no package flow at least for one board. Fixes: FS#1664 Signed-off-by: Mathias Kresin <dev@kresin.me>

| | | | | | | | | | Since kernel 4.1 bcm47xx_nvram_gpio_pin() is now defined in a global header and can be safely called even on non-Broadcom platforms. This change makes b53 look for "robo_reset" on ARCH_BCM_5301X and slightly simplifies the code. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

* generic: swconfig: reduce lock duration on sysfs filesKevin Darbyshire-Bryant2018-02-141-8/+12

* generic: swconfig: add mode led attributeKevin Darbyshire-Bryant2018-02-141-12/+125
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add sysfs 'mode' attribute to swconfig controlled LEDs. swconfig 'link state' LEDs blink in the presence of port traffic. This behaviour becomes more obvious as switches start to support get_port_stats() e.g. commits 0369e358916ef092a1644334f5dd1412051b68a4, 3056d09b4046e0eb0f6de0f3f5432cd9fa86fc51, 4ddbc43cc15c2fa128a2f169964ef7eb508cf2c5, 4d8a66d9346373c2a7fcac5bdae3f662a9dbd9df. This blinking can be confusing/distracting if the switch has other LEDs used to indicate traffic. Provide a 'mode' sysfs attribute that controls the blink on traffic behaviour. mode - either "none" (LED is off) or a space separated list of one or more: link: LED's normal state reflects whether the link is up (has carrier) or not tx: LED blinks on transmitted data rx: LED blinks on receive data Note that 'link' considers any port speed mask that may be applicable. e.g. if an LED is configured to indicate 1Gbit link speed and mode is set to 'link rx tx' but the port is connected at 100Mbit then the LED will not light or blink. A mode of 'tx rx' will blink in the presence of traffic only if the port matches the rate (if configured) This maintains compatibility with existing behaviour. Attribute is 'link tx rx' by default for backwards compatible behaviour. Many thanks to Thibaut Varene for providing a more sensible led_event routine after I had mangled the original, and other coding style hints.

In the configuration I deactivated some of the new possible security features like: CONFIG_REFCOUNT_FULL CONFIG_SLAB_FREELIST_HARDENED CONFIG_SOFTLOCKUP_DETECTOR CONFIG_WARN_ALL_UNSEEDED_RANDOM And these overlay FS options are also deactivated: CONFIG_OVERLAY_FS_INDEX CONFIG_OVERLAY_FS_REDIRECT_DIR I activated this: CONFIG_FORTIFY_SOURCE CONFIG_POSIX_TIMERS CONFIG_SLAB_MERGE_DEFAULT CONFIG_WATCHDOG_HANDLE_BOOT_ENABLED I am not sure if I did the porting correct for the following patches: target/linux/generic/backport-4.14/020-backport_netfilter_rtcache.patch target/linux/generic/hack-4.14/220-gc_sections.patch target/linux/generic/hack-4.14/321-powerpc_crtsavres_prereq.patch target/linux/generic/pending-4.14/305-mips_module_reloc.patch target/linux/generic/pending-4.14/611-netfilter_match_bypass_default_table.patch target/linux/generic/pending-4.14/680-NET-skip-GRO-for-foreign-MAC-addresses.patch Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* generic: make mtdsplit-tplink.c honor rootfs offsetThibaut VARÈNE2017-11-081-6/+6
| | | | | | | | | | | | | | | | | | | | The splitter ignored the rootfs offset from the header, probably because until c1e6e61 it was invalid. This patch fixes the splitter to use the now correct header data. Regarding target/linux/ar71xx/files/drivers/mtd/tplinkpart.c, this particular splitter "falls back" to the correct rootfs offset reading and as such it doesn't need to be updated, although it will report a kernel partition length that can be larger than the actual length as it assumes that partition fills the entire segment up to the rootfs partition.

* generic: drop support for get_port_stats() on ar8xxxThibaut VARENE2017-09-133-59/+18
| | | | | | | | | | | | | | | | The implementation is not efficient on ar8xxx switches. It triggers high CPU load and degrades device performance. The high CPU load has been traced down to the ar8xxx_reg_wait() call in ar8xxx_mib_op(), which has to usleep_range() till the MIB busy flag set by the request to update the MIB counter is cleared. This commit removes the get_port_stats() code introduced in 4d8a66d and leaves a note for future hacker's beware. Fixes: FS#1004 Signed-off-by: Thibaut VARENE <hacks@slashdirt.org>

* generic: make switch_port_stats tx/rx_bytes long longThibaut VARENE2017-09-012-3/+3
| | | | | | | | | | | | | | This generic structure defines tx_bytes and rx_bytes as unsigned long (u32), while several devices would typically report unsigned long long (u64). The code can work as is, but there's a chance that with a sufficiently fast interface the overflow might happen too fast to be correctly noticed by the consumers of this data. This patch makes both field unsigned long long and updates the only known consumer of this data: swconfig_leds.c Signed-off-by: Thibaut VARENE <hacks@slashdirt.org>

* brcm47xx: resolve GPIO conflict for WRT54GSv1Mirko Parthey2017-07-022-6/+0
| | | | | | | | | | | | | | | On the Linksys WRT54GSv1, the adm6996 switch driver and the gpio_button_hotplug module both claim GPIO 6, which is connected to the Reset button. When the switch driver's request wins, the Reset button cannot work. This makes it impossible to enter failsafe mode without a serial console.

* mvswitch: fix autonegotiation issueSergey Ryazanov2017-06-071-0/+7
| | | | | | | | | | | | | | | The Marvel 88E6060 switch has an MDIO interface, but does not emulate regular PHY behavior for the host. The network core can not detect using the generic code, whether the connection via the attached PHY can be used or not. The PHY's state machine is stuck in a state of auto-negotiation and does not go any further so the Ethernet interface of the router stay forever in the not-runing state. Fix this issue by implementing the aneg_done callback to be able to inform the network core that the Ethernet interface link to which the switch is connected can be marked as RUNNING.

| | | | | | | | | | | | | | | | RGMII RX delay setting needs to be always specified for AR8337 to avoid port 5 RX hang on high traffic / flood conditions. Also, the HOL registers that set per-port and per-packet-priority buffer sizes are updated with the reduced values suggested by the QCA switch team. Finally, AR8327 reserved register fixups are disabled for the AR8337. This patch is adapted from the Code Aurora QSDK, but with magic values mapped to proper defines.

* kernel: mtdsplit: Add support for Mikrotik NOR firmwareThibaut VARENE2017-02-223-0/+123
| | | | | | | | | | | | | | | | The RouterBOOT bootloader does not care where the kernel lives in the SPI flash, all that matters is that the kernel is wrapped in the custom yaffs container as generated by kernel2minor. This container has a fixed signature as follows: 00000000 00 00 00 01 00 00 00 01 ff ff 6b 65 72 6e 65 6c |..........kernel| This patch adds mtdsplit support for identifying that signature and triggering the search for the rootfs. rootfs is expected at EB boundary since we use wget mtd_find_rootfs_from(). We make no use of the yaffs file size field because it contains invalid data in the image generated by kernel2minor. Signed-off-by: Thibaut VARENE <hacks@slashdirt.org>
