Without this rollback, the thermal zone is still registered during the error path, whereas its private data is freed upon the destruction of the underlying bus device due to the use of devm_kzalloc(). This results in use after free. Fix this by calling mlxsw_thermal_fini() from the appropriate place in the error path. Fixes: a50c1e35 ("mlxsw: core: Implement thermal zone") Signed-off-by:

The shared buffer pools are containers whose size is used to calculate the maximum usage for packets from / to a specific port / {port, PG/TC}, when dynamic threshold is employed. While it's perfectly fine for the sum of the pools to exceed the maximum size of the shared buffer, a single pool cannot. Add a check when the pool size is set and forbid sizes larger than the maximum size of the shared buffer. Without the patch: $ devlink sb pool set pci/0000:03:00.0 pool 0 size 999999999 thtype dynamic // No error is returned With the patch: $ devlink sb pool set pci/0000:03:00.0 pool 0 size 999999999 thtype dynamic devlink answers: Invalid argument Signed-off-by:

If device_release_driver(&phydev->mdio.dev) is called, it releases all resources belonging to the PHY device. Hence the subsequent call to phy_led_triggers_unregister() will access already freed memory when unregistering the LEDs. Move the call to phy_led_triggers_unregister() before the possible call to device_release_driver() to fix this.

Jerome Brunet says: ==================== Fix OdroidC2 Gigabit Tx link issue This patchset fixes an issue with the OdroidC2 board (DWMAC + RTL8211F). The platform seems to enter LPI on the Rx path too often while performing relatively high TX transfer. This eventually break the link (both Tx and Rx), and require to bring the interface down and up again to get the Rx path working again. The root cause of this issue is not fully understood yet but disabling EEE advertisement on the PHY prevent this feature to be negotiated. With this change, the link is stable and reliable, with the expected throughput performance. The patchset adds options in the generic phy driver to disable EEE advertisement, through device tree. The way it is done is very similar to the handling of the max-speed property. Changes since V2: [2] - Rename "eee-advert-disable" to "eee-broken-modes" to make the intended purpose of this option clear (flag broken configuration, not a configuration option) - Add DT bindings constants so the DT configuration is more user friendly - Submit to net-next instead of net. Changes since V1: [1] - Disable the advertisement of EEE in the generic code instead of the realtek driver.

This patch adds an option to disable EEE advertisement in the generic PHY by providing a mask of prohibited modes corresponding to the value found in the MDIO_AN_EEE_ADV register. On some platforms, PHY Low power idle seems to be causing issues, even breaking the link some cases. The patch provides a convenient way for these platforms to disable EEE advertisement and work around the issue. Signed-off-by:

The dwmac4 IP can synthesized with 1-8 number of tx queues. On an IP synthesized with DWC_EQOS_NUM_TXQ > 1, all txqueues are disabled by default. For these IPs, the bitfield TXQEN is R/W. Always enable tx queue 0. The write will have no effect on IPs synthesized with DWC_EQOS_NUM_TXQ == 1. The driver does still not utilize more than one tx queue in the IP. Signed-off-by:

mlx4 stats are chaotic because a deferred work queue is responsible to update them every 250 ms.

Saeed Mahameed says: ==================== Mellanox 100G mlx5 DCBX and ethtool updates This series provides the following mlx5 updates: From Huy: DCBX CEE API and DCBX firmware/host modes support. - 1st patch ensures the dcbnl_rtnl_ops is published only when the qos capability bits is on. - 2nd patch adds the support for CEE interfaces into mlx5 dcbnl_rtnl_ops - 3rd patch refactors ETS query to read ETS configuration directly from firmware rather than having a software shadow to it. The existing IEEE interfaces stays the same. - 4th patch adds the support for MLX5_REG_DCBX_PARAM and MLX5_REG_DCBX_APP firmware commands to manipulate mlx5 DCBX mode. - 5th patch adds the driver support for the new DCBX firmware. This ensures the backward compatibility versus the old and new firmware. With the new DCBX firmware, qos settings can be controlled by either firmware or software depending on the DCBX mode. From Kamal and Saeed: - mlx5 self-test support. From Shaker: - Private flag to give the user the ability to enable/disable mlx5 CQE compression. V1->V2: - Check ETS capability where needed in: ("net/mlx5e: Read ETS settings directly from firmware") - Fix return value of mlx5e_dcbnl_switch_to_host_mode in: ("net/mlx5e: ConnectX-4 firmware support for DCBX") - Update commit message of: ("net/mlx5e: ConnectX-4 firmware support for DCBX") - Fix two sparse static check warnings in en_selftest.c This series was generated against commit: e5f12b3f ("Merge branch 'mlxsw-trap-groups-and-policers'") ==================== Signed-off-by:

Issue description: Current implementation saves the ETS settings from user in a temporal soft copy and returns this settings when user queries the ETS settings. With the new DCBX firmware, the ETS settings can be changed by firmware when the DCBX is in firmware controlled mode. Therefore, user will obtain wrong values from the temporal soft copy. Solution: 1. Read the ETS settings directly from firmware. 2. For tc_tsa: a. Initialize tc_tsa to vendor IEEE_8021QAZ_TSA_VENDOR at netdev creation. b. When reading ETS setting from FW, if the traffic class bandwidth is less than 100, set tc_tsa to IEEE_8021QAZ_TSA_ETS. This implementation solves the scenarios when the DCBX is in FW control and willing bit is on which means the ETS setting is dictated by remote switch. Also check ETS capability where needed.

We use single queue even if multiqueue is enabled and let admin to enable it through ethtool later. This is used to avoid possible regression (small packet TCP stream transmission). But looks like an overkill since: - single queue user can disable multiqueue when launching qemu - brings extra troubles for the management since it needs extra admin tool in guest to enable multiqueue - multiqueue performs much better than single queue in most of the cases So this patch enables multiqueue by default: if #queues is less than or equal to #vcpu, enable as much as queue pairs; if #queues is greater than #vcpu, enable #vcpu queue pairs.

1) The test_lru_map and test_lru_dist fails building on my machine since the sys/resource.h header is not included. 2) test_verifier fails in one test case where we try to call an invalid function, since the verifier log output changed wrt printing function names. 3) Current selftest suite code relies on sysconf(_SC_NPROCESSORS_CONF) for retrieving the number of possible CPUs. This is broken at least in our scenario and really just doesn't work. glibc tries a number of things for retrieving _SC_NPROCESSORS_CONF. First it tries equivalent of /sys/devices/system/cpu/cpu[0-9]* | wc -l, if that fails, depending on the config, it either tries to count CPUs in /proc/cpuinfo, or returns the _SC_NPROCESSORS_ONLN value instead. If /proc/cpuinfo has some issue, it returns just 1 worst case. This oddity is nothing new [1], but semantics/behaviour seems to be settled. _SC_NPROCESSORS_ONLN will parse /sys/devices/system/cpu/online, if that fails it looks into /proc/stat for cpuX entries, and if also that fails for some reason, /proc/cpuinfo is consulted (and returning 1 if unlikely all breaks down). While that might match num_possible_cpus() from the kernel in some cases, it's really not guaranteed with CPU hotplugging, and can result in a buffer overflow since the array in user space could have too few number of slots, and on perpcu map lookup, the kernel will write beyond that memory of the value buffer. William Tu reported such mismatches: [...] The fact that sysconf(_SC_NPROCESSORS_CONF) != num_possible_cpu() happens when CPU hotadd is enabled. For example, in Fusion when setting vcpu.hotadd = "TRUE" or in KVM, setting ./qemu-system-x86_64 -smp 2, maxcpus=4 ... the num_possible_cpu() will be 4 and sysconf() will be 2 [2]. [...] Documentation/cputopology.txt says /sys/devices/system/cpu/possible outputs cpu_possible_mask. That is the same as in num_possible_cpus(), so first step would be to fix the _SC_NPROCESSORS_CONF calls with our own implementation. Later, we could add support to bpf(2) for passing a mask via CPU_SET(3), for example, to just select a subset of CPUs. BPF samples code needs this fix as well (at least so that people stop copying this). Thus, define bpf_num_possible_cpus() once in selftests and import it from there for the sample code to avoid duplicating it. The remaining sysconf(_SC_NPROCESSORS_CONF) in samples are unrelated.

Since we recently converted the BPF filesystem over to use mount_nodev(), we now have the possibility to also hold mount options in sb's s_fs_info. This work implements mount options support for specifying permissions on the sb's inode, which will be used by tc when it manually needs to mount the fs. Signed-off-by:
