2023-02-03net: phylink: move phy_device_free() to correctly release phy deviceClément Léger
After calling fwnode_phy_find_device(), the phy device refcount is incremented. Then, when the phy device is attached to a netdev with phy_attach_direct(), the refcount is also incremented but only decremented in the caller if phy_attach_direct() fails. Move phy_device_free() before the "if" to always release it correctly. Indeed, either phy_attach_direct() failed and we don't want to keep a reference to the phydev or it succeeded and a reference has been taken internally.

Conversion to gpiod API done in commit 468ba54bd616 ("fec: convert to gpio descriptor") clashed with gpiolib applying the same quirk to the reset GPIO polarity (introduced in commit b02c85c9458c). This results in the reset line being left active/device being left in reset state when reset line is "active low". Remove handling of 'phy-reset-active-high' property from the driver and rely on gpiolib to apply needed adjustments to avoid ending up with the double inversion/flipped logic.

2023-02-02selftests/bpf: introduce XDP compliance test toolLorenzo Bianconi
Introduce xdp_features tool in order to test XDP features supported by the NIC and match them against advertised ones. In order to test supported/advertised XDP features, xdp_features must run on the Device Under Test (DUT) and on a Tester device. xdp_features opens a control TCP channel between DUT and Tester devices to send control commands from Tester to the DUT and a UDP data channel where the Tester sends UDP 'echo' packets and the DUT is expected to reply back with the same packet. DUT installs multiple XDP programs on the NIC to test XDP capabilities and reports back to the Tester some XDP stats. Currently xdp_features supports the following XDP features: - XDP_DROP - XDP_ABORTED - XDP_PASS - XDP_TX - XDP_REDIRECT - XDP_NDO_XMIT Co-developed-by: Kumar Kartikeya Dwivedi <memxor@gmail.com> Signed-off-by: Kumar Kartikeya Dwivedi <memxor@gmail.com> Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Acked-by: Stanislav Fomichev <sdf@google.com> Link: https://lore.kernel.org/r/7c1af8e7e6ef0614cf32fa9e6bdaa2d8d605f859.1675245258.git.lorenzo@kernel.org Signed-off-by: Alexei Starovoitov <ast@kernel.org>

2023-02-02drivers: net: turn on XDP featuresMarek Majtyka
A summary of the flags being set for various drivers is given below. Note that XDP_F_REDIRECT_TARGET and XDP_F_FRAG_TARGET are features that can be turned off and on at runtime. This means that these flags may be set and unset under RTNL lock protection by the driver. Hence, READ_ONCE must be used by code loading the flag value. Also, these flags are not used for synchronization against the availability of XDP resources on a device. It is merely a hint, and hence the read may race with the actual teardown of XDP resources on the device. This may change in the future, e.g. operations taking a reference on the XDP resources of the driver, and in turn inhibiting turning off this flag. However, for now, it can only be used as a hint to check whether device supports becoming a redirection target. Turn 'hw-offload' feature flag on for: - netronome (nfp) - netdevsim. Turn 'native' and 'zerocopy' features flags on for: - intel (i40e, ice, ixgbe, igc) - mellanox (mlx5). - stmmac - netronome (nfp) Turn 'native' features flags on for: - amazon (ena) - broadcom (bnxt) - freescale (dpaa, dpaa2, enetc) - funeth - intel (igb) - marvell (mvneta, mvpp2, octeontx2) - mellanox (mlx4) - mtk_eth_soc - qlogic (qede) - sfc - socionext (netsec) - ti (cpsw) - tap - tsnep - veth - xen - virtio_net. Turn 'basic' (tx, pass, aborted and drop) features flags on for: - netronome (nfp) - cavium (thunder) - hyperv.

2023-02-02netdev-genl: create a simple family for netdev stuffJakub Kicinski
Add a Netlink spec-compatible family for netdevs. This is a very simple implementation without much thought going into it. It allows us to reap all the benefits of Netlink specs, one can use the generic client to issue the commands: $ ./cli.py --spec netdev.yaml --dump dev_get [{'ifindex': 1, 'xdp-features': set()}, {'ifindex': 2, 'xdp-features': {'basic', 'ndo-xmit', 'redirect'}}, {'ifindex': 3, 'xdp-features': {'rx-sg'}}] the generic python library does not have flags-by-name support, yet, but we also don't have to carry strings in the messages, as user space can get the names from the spec.

2023-02-02of/address: Return an error when no valid dma-ranges are foundMark Brown
Commit 7a8b64d17e35 ("of/address: use range parser for of_dma_get_range") converted the parsing of dma-range properties to use code shared with the PCI range parser. The intent was to introduce no functional changes however in the case where we fail to translate the first resource instead of returning -EINVAL the new code we return 0. Restore the previous behaviour by returning an error if we find no valid ranges, the original code only handled the first range but subsequently support for parsing all supplied ranges was added. This avoids confusing code using the parsed ranges which doesn't expect to successfully parse ranges but have only a list terminator returned, this fixes breakage with so far as I can tell all DMA for on SoC devices on the Socionext Synquacer platform which has a firmware supplied DT. A bisect identified the original conversion as triggering the issues there.

Since Linux 5.19 this error is observed: sysfs: cannot create duplicate filename '/devices/platform/of-display' This is because multiple devices with the same name 'of-display' are created on the same bus. Update the code to create numbered device names for the displays. Also, fix a node refcounting issue when exiting the boot display loop. cc: linuxppc-dev@lists.ozlabs.org References: https://bugzilla.kernel.org/show_bug.cgi?id=216095 Fixes: 52b1b46c39ae ("of: Create platform devices for OF framebuffers") Reported-by: Erhard F. <erhard_f@mailbox.org> Suggested-by: Thomas Zimmermann <tzimmermann@suse.de> Signed-off-by: Michal Suchanek <msuchanek@suse.de> Link: https://lore.kernel.org/r/20230201162247.3575506-1-robh@kernel.org [robh: Rework to avoid node refcount leaks] Signed-off-by: Rob Herring <robh@kernel.org>

2023-02-02tracing: Fix poll() and select() do not work on per_cpu trace_pipe and ↵Shiju Jose
trace_pipe_raw poll() and select() on per_cpu trace_pipe and trace_pipe_raw do not work since kernel 6.1-rc6. This issue is seen after the commit 42fb0a1e84ff525ebe560e2baf9451ab69127e2b ("tracing/ring-buffer: Have polling block on watermark"). This issue is firstly detected and reported, when testing the CXL error events in the rasdaemon and also erified using the test application for poll() and select(). This issue occurs for the per_cpu case, when calling the ring_buffer_poll_wait(), in kernel/trace/ring_buffer.c, with the buffer_percent > 0 and then wait until the percentage of pages are available. The default value set for the buffer_percent is 50 in the kernel/trace/trace.c. As a fix, allow userspace application could set buffer_percent as 0 through the buffer_percent_fops, so that the task will wake up as soon as data is added to any of the specific cpu buffer.

The reason is that a pointer to a string is passed to an inline assembly; this string however is located on the stack, while the instruction within the inline assembly expects a physicial address. Fix this by copying the string to a kmalloc'ed buffer. - The diag288_wdt watchdog module does not indicate that it accesses memory from an inline assembly, which it does. Add "memory" to the clobber list to prevent the compiler from optimizing code incorrectly away. - Pass size of the uncompressed kernel image to __decompress() call. Otherwise the kernel image decompressor may corrupt/overwrite an initrd. This was reported to happen on s390 after commit 2aa14b1ab2c4 ("zstd: import usptream v1.5.2"). * tag 's390-6.2-4' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390/decompressor: specify __decompress() buf len to avoid overflow watchdog: diag288_wdt: fix __diag288() inline assembly watchdog: diag288_wdt: do not use stack buffers for hardware data

The code expect the PHY to be in power down which is only true after reset. Allow changes of the SGMII parameters more than once. Only power down when reconfiguring to avoid bouncing the link when there's no reason to - based on code from Russell King. There are cases when the SGMII_PHYA_PWD register contains 0x9 which prevents SGMII from working. The SGMII still shows link but no traffic can flow. Writing 0x0 to the PHYA_PWD register fix the issue. 0x0 was taken from a good working state of the SGMII interface.
