* net: sched: cls_u32: disallow linking to root hnodeAl Viro2018-10-081-0/+4
| | | | | | | | | | | | | | | | | | | | Operation makes no sense. Nothing will actually break if we do so (depth limit in u32_classify() will prevent infinite loops), but according to maintainers it's best prohibited outright. NOTE: doing so guarantees that u32_destroy() will trigger the call of u32_destroy_hnode(); we might want to make that unconditional. Test: tc qdisc add dev eth0 ingress tc filter add dev eth0 parent ffff: protocol ip prio 100 u32 \ link 800: offset at 0 mask 0f00 shift 6 plus 0 eat match ip protocol 6 ff should fail with Error: cls_u32: Not linking to root node Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Jamal Hadi Salim <jhs@mojatatu.com> Signed-off-by: David S.

* net: sched: cls_u32: mark root hnode explicitlyAl Viro2018-10-081-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ... and produce consistent error on attempt to delete such. Existing check in u32_delete() is inconsistent - after tc qdisc add dev eth0 ingress tc filter add dev eth0 parent ffff: protocol ip prio 100 handle 1: u32 \ divisor 1 tc filter add dev eth0 parent ffff: protocol ip prio 200 handle 2: u32 \ divisor 1 both tc filter delete dev eth0 parent ffff: protocol ip prio 100 handle 801: u32 and tc filter delete dev eth0 parent ffff: protocol ip prio 100 handle 800: u32 will fail (at least with refcounting fixes), but the former will complain about an attempt to remove a busy table, while the latter will recognize it as root and yield "Not allowed to delete root node" instead. The problem with the existing check is that several tcf_proto instances might share the same tp->data and handle-to-hnode lookup will be the same for all of them. So comparing an hnode to be deleted with tp->root won't catch the case when one tp is used to try deleting the root of another. Solution is trivial - mark the root hnodes explicitly upon allocation and check for that.

Both PHYs are 4-port PHY that are 10/100/1000BASE-T, 100BASE-FX, 1000BASE-X and triple-speed copper SFP capable, can communicate with the MAC via SGMII, QSGMII or 1000BASE-X, supports downshifting and can set the blinking pattern of each of its 4 LEDs, supports SyncE as well as HP Auto-MDIX detection. VSC8574 supports WOL and VSC8584 supports hardware offloading of MACsec. This patch series add support for 10/100/1000BASE-T, SGMII/QSGMII link with the MAC, downshifting, HP Auto-MDIX detection and blinking pattern for their 4 LEDs. They have also an internal Intel 8051 microcontroller whose firmware needs to be patched when the PHY is reset. If the 8051's firmware has the expected CRC, its patching can be skipped. The microcontroller can be accessed from any port of the PHY, though the CRC function can only be done through the PHY that is the base PHY of the package (internal address 0) due to a limitation of the firmware. The GPIO register bank is a set of registers that are common to all PHYs in the package. So any modification in any register of this bank affects all PHYs of the package. If the PHYs haven't been reset before booting the Linux kernel and were configured to use interrupts for e.g. link status updates, it is required to clear the interrupts mask register of all PHYs before being able to use interrupts with any PHY. The first PHY of the package that will be init will take care of clearing all PHYs interrupts mask registers. Thus, we need to keep track of the init sequence in the package, if it's already been done or if it's to be done. Most of the init sequence of a PHY of the package is common to all PHYs in the package, thus we use the SMI broadcast feature which enables us to propagate a write in one register of one PHY to all PHYs in the same package. We also introduce a new development board called PCB120 which exists in variants for VSC8584 and VSC8574 (and that's the only difference to the best of my knowledge). I suggest patches 1 to 3 go through net tree and patches 4 and 5 go through MIPS tree. Patches going through net tree and those going through MIPS tree do not depend on one another.

Registers can only be accessed from one page, if we need a register from another page, we need to switch the page and the registers of all other pages are not accessible anymore. Basically, to read register 5 from page 0, 1, 2, etc., you do the same phy_read(phydev, 5); but you need to set the desired page beforehand. In order to guarantee that two concurrent functions do not change the page, we need to do some locking per page. This can be achieved with the use of phy_select_page and phy_restore_page functions but phy_write/read calls in-between those two functions shall be replaced by their lock-free alternative __phy_write/read. The Microsemi PHYs have several counters so let's make them available as PHY statistics. The VSC 8530/31/40/41 also need to update their EEE init sequence in order to avoid packet losses and improve performance. This patch series also makes some minor cosmetic changes to the driver. v3: - add reviewed-by, - use phy_read/write/modify_paged whenever possible instead of the combo phy_select_page, __phy_read/write/modify, phy_restore_page when only one __phy_read/write/modify was executed, v2: - add patch to migrate MSCC driver to use phy_restore/select_page, - migrate all patches from v1 to use those two functions, - put the multiple lines of constants writes in an array and iterate over it to write the values, - add reviewed-bys, ==================== Signed-off-by: David S.
