2020-01-20net: phy: add generic ndo_do_ioctl handler phy_do_ioctlHeiner Kallweit2-0/+16
A number of network drivers has the same glue code to use phy_mii_ioctl as ndo_do_ioctl handler. So let's add such a generic ndo_do_ioctl handler to phylib. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2020-01-20net: phylink: allow in-band AN for USXGMIIAlex Marginean1-0/+1
USXGMII supports passing link information in-band between PHY and MAC PCS, add it to the list of protocols that support in-band AN mode. Being a MAC-PHY protocol that can auto-negotiate link speeds up to 10 Gbps, we populate the initial supported mask with the entire spectrum of link modes up to 10G that PHYLINK supports, and we let the driver reduce that mask in its .phylink_validate method.

2020-01-20net: phy: don't crash in phy_read/_write_mmd without a PHY driverAlex Marginean1-2/+2
The APIs can be used by Ethernet drivers without actually loading a PHY driver. This may become more widespread in the future with 802.3z compatible MAC PCS devices being locally driven by the MAC driver when configuring for a PHY mode with in-band negotiation.

2020-01-20net: phylink: Allow 2.5BASE-T, 5GBASE-T and 10GBASE-T for the 10G link modesVladimir Oltean1-0/+4
For some reason, PHYLINK does not put the copper modes for 802.3bz (NBASE-T) and 802.3an-2006 (10GBASE-T) in the PHY's supported mask, when the PHY-MAC connection is a 10G-capable one (10GBase-KR, 10GBase-R, USXGMII). One possible way through which the cable side can work at the lower speed is by having the PHY emit PAUSE frames towards the MAC. So fix that omission. Also include the 2500Base-X fiber mode in this list while we're at it. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2020-01-19Merge branch 'mlxsw-Add-tunnel-devlink-trap-support'David S. Miller14-4/+981
Ido Schimmel says: ==================== mlxsw: Add tunnel devlink-trap support This patch set from Amit adds support in mlxsw for tunnel traps and a few additional layer 3 traps that can report drops and exceptions via devlink-trap. These traps allow the user to more quickly diagnose problems relating to tunnel decapsulation errors, such as packet being too short to decapsulate or a packet containing wrong GRE key in its GRE header. Patch set overview: Patches #1-#4 add three additional layer 3 traps. Two of which are mlxsw-specific as they relate to hardware-specific errors. The patches include documentation of each trap and selftests. Patches #5-#8 are preparations. They ensure that the correct ECN bits are set in the outer header during IPinIP encapsulation and that packets with an invalid ECN combination in underlay and overlay are trapped to the kernel and not decapsulated in hardware. Patches #9-#15 add support for two tunnel related traps. Each trap is documented and selftested using both VXLAN and IPinIP tunnels, if applicable. ==================== Signed-off-by: David S.

Saeed Mahameed says: ==================== Mellanox, mlx5 E-Switch chains and prios This series has two parts, 1) A merge commit with mlx5-next branch that include updates for mlx5 HW layouts needed for this and upcoming submissions. 2) From Paul, Increase the number of chains and prios Currently the Mellanox driver supports offloading tc rules that are defined on the first 4 chains and the first 16 priorities. The restriction stems from the firmware flow level enforcement requiring a flow table of a certain level to point to a flow table of a higher level. This limitation may be ignored by setting the ignore_flow_level bit when creating flow table entries. Use unmanaged tables and ignore flow level to create more tables than declared by fs_core steering. Manually manage the connections between the tables themselves. HW table is instantiated for every tc <chain,prio> tuple. The miss rule of every table either jumps to the next <chain,prio> table, or continues to slow_fdb. This logic is realized by following this sequence: 1. Create an auto-grouped flow table for the specified priority with reserved entries Reserved entries are allocated at the end of the flow table. Flow groups are evaluated in sequence and therefore it is guaranteed that the flow group defined on the last FTEs will be the last to evaluate. Define a "match all" flow group on the reserved entries, providing the platform to add table miss actions. 2. Set the miss rule action to jump to the next <chain,prio> table or the slow_fdb. 3. Link the previous priority table to point to the new table by updating its miss rule. Please pull and let me know if there's any problem. ==================== Signed-off-by: David S.

T6 can support 2 egress traffic management channels per port to double the total number of traffic classes that can be configured. In this configuration, if the class belongs to the other channel, then all the queues must be bound again explicitly to the new class, for the rate limit parameters on the other channel to take effect. So, always explicitly bind all queues to the port rate limit traffic class, regardless of the traffic management channel that it belongs to. Also, only bind queues to port rate limit traffic class, if all the queues don't already belong to an existing different traffic class.

Flow control is used with 2500Base-X and AQR PHYs to do rate adaptation between line side 100/1000 links and MAC running at 2.5G. This is independent of the flow control configuration settled on line side though AN. In general, allowing the MAC to handle flow control even if not negotiated with the link partner should not be a problem, so the patch just enables it in all cases.

2020-01-18riscv: Less inefficient gcc tishift helpers (and export their symbols)Olof Johansson2-18/+61
The existing __lshrti3 was really inefficient, and the other two helpers are also needed to compile some modules. Add the missing versions, and export all of the symbols like arm64 already does. This code is based on the assembly generated by libgcc builds. This fixes a build break triggered by ubsan: riscv64-unknown-linux-gnu-ld: lib/ubsan.o: in function `.L2': ubsan.c:(.text.unlikely+0x38): undefined reference to `__ashlti3' riscv64-unknown-linux-gnu-ld: ubsan.c:(.text.unlikely+0x42): undefined reference to `__ashrti3' Signed-off-by: Olof Johansson <olof@lixom.net> [paul.walmsley@sifive.com: use SYM_FUNC_{START,END} instead of ENTRY/ENDPROC; note libgcc origin] Signed-off-by: Paul Walmsley <paul.walmsley@sifive.com>

Pull thread fixes from Christian Brauner: "Here is an urgent fix for ptrace_may_access() permission checking. Commit 69f594a38967 ("ptrace: do not audit capability check when outputing /proc/pid/stat") introduced the ability to opt out of audit messages for accesses to various proc files since they are not violations of policy. While doing so it switched the check from ns_capable() to has_ns_capability{_noaudit}(). That means it switched from checking the subjective credentials (ktask->cred) of the task to using the objective credentials (ktask->real_cred). This is appears to be wrong. ptrace_has_cap() is currently only used in ptrace_may_access() And is used to check whether the calling task (subject) has the CAP_SYS_PTRACE capability in the provided user namespace to operate on the target task (object). According to the cred.h comments this means the subjective credentials of the calling task need to be used. With this fix we switch ptrace_has_cap() to use security_capable() and thus back to using the subjective credentials. As one example where this might be particularly problematic, Jann pointed out that in combination with the upcoming IORING_OP_OPENAT{2} feature, this bug might allow unprivileged users to bypass the capability checks while asynchronously opening files like /proc/*/mem, because the capability checks for this would be performed against kernel credentials. To illustrate on the former point about this being exploitable: When io_uring creates a new context it records the subjective credentials of the caller. Later on, when it starts to do work it creates a kernel thread and registers a callback. The callback runs with kernel creds for ktask->real_cred and ktask->cred. To prevent this from becoming a full-blown 0-day io_uring will call override_cred() and override ktask->cred with the subjective credentials of the creator of the io_uring instance. With ptrace_has_cap() currently looking at ktask->real_cred this override will be ineffective and the caller will be able to open arbitray proc files as mentioned above. Luckily, this is currently not exploitable but would be so once IORING_OP_OPENAT{2} land in v5.6. Let's fix it now. To minimize potential regressions I successfully ran the criu testsuite. criu makes heavy use of ptrace() and extensively hits ptrace_may_access() codepaths and has a good change of detecting any regressions. Additionally, I succesfully ran the ptrace and seccomp kernel tests" * tag 'for-linus-2020-01-18' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: ptrace: reintroduce usage of subjective credentials in ptrace_has_cap()
