This appears\nto have been done because its use is within functions that take the\nport_info as a primary argument.\n\nHowever, this complicates managing the lifecycle of the field. The\nport_info structure is allocated in ice_init_hw() using devm, and it is\nnot released until the devm cleanup when the driver is unloaded.\n\nThe ice_init_hw() function is called in many places, including devlink\nreload, and possibly during DDP load after updating the Tx scheduler\nlayout.\n\nAdding a call of xa_destroy to the ice_deinit_hw() causes Sashiko to raise\nmultiple concerns due to potential ordering issues and possible ways that\nport_info could be a dangling reference.\n\nTo handle this, move the sched_node_ids out of port_info and into the hw\nstructure. All users of the array already have a pointer to hw anyways, and\nthere is only one sched_node_ids per adapter. While here, remove the overly\nverbose comment explaining the nature of the sched_node_ids xarray.\n\nAdd the missing xa_destroy to the cleanup path and to ice_deinit_hw(),\nensuring that we properly release the xarray memory.\n\nThis was caught by Sashiko during development of unrelated code."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/intel/ice/ice_common.c","drivers/net/ethernet/intel/ice/ice_sched.c","drivers/net/ethernet/intel/ice/ice_type.h"],"versions":[{"version":"a388961be5ed8ee037ac68220e389bc4e9339a39","lessThan":"09a7cdf8fffb065a8aa30cfa604ff4a65cbf04c9","status":"affected","versionType":"git"},{"version":"16dfa49406bc5e1f4cbb115027cbd719d7e6c930","lessThan":"c075a91fe5762d314e6e182d37d29cf874bd314a","status":"affected","versionType":"git"},{"version":"16dfa49406bc5e1f4cbb115027cbd719d7e6c930","lessThan":"44cdd6b7e036303f7fecf841cf23c05a4a4faf2d","status":"affected","versionType":"git"},{"version":"16dfa49406bc5e1f4cbb115027cbd719d7e6c930","lessThan":"f5463bc124c0d6f922e272336584730c5c61c4f1","status":"affected","versionType":"git"},{"version":"16dfa49406bc5e1f4cbb115027cbd719d7e6c930","lessThan":"d6f38fb12069fb1edf762962b5fcf3f42d643b47","status":"affected","versionType":"git"},{"version":"16dfa49406bc5e1f4cbb115027cbd719d7e6c930","lessThan":"53432c4c3e869076350aef319534431af8ba99c1","status":"affected","versionType":"git"},{"version":"6.1.95","lessThan":"6.1.189","status":"affected","versionType":"semver"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/intel/ice/ice_common.c","drivers/net/ethernet/intel/ice/ice_sched.c","drivers/net/ethernet/intel/ice/ice_type.h"],"versions":[{"version":"6.2","status":"affected"},{"version":"0","lessThan":"6.2","status":"unaffected","versionType":"semver"},{"version":"6.1.189","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.158","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.111","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.7","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.1.95","versionEndExcluding":"6.1.189"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.2","versionEndExcluding":"6.6.158"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.2","versionEndExcluding":"6.12.111"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.2","versionEndExcluding":"6.18.53"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.2","versionEndExcluding":"7.2.7"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.2","versionEndExcluding":"7.3-rc3"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/09a7cdf8fffb065a8aa30cfa604ff4a65cbf04c9"},{"url":"https://git.kernel.org/stable/c/c075a91fe5762d314e6e182d37d29cf874bd314a"},{"url":"https://git.kernel.org/stable/c/44cdd6b7e036303f7fecf841cf23c05a4a4faf2d"},{"url":"https://git.kernel.org/stable/c/f5463bc124c0d6f922e272336584730c5c61c4f1"},{"url":"https://git.kernel.org/stable/c/d6f38fb12069fb1edf762962b5fcf3f42d643b47"},{"url":"https://git.kernel.org/stable/c/53432c4c3e869076350aef319534431af8ba99c1"}],"title":"ice: add missing xa_destroy for sched_node_ids","x_generator":{"engine":"bippy-1.2.0"}}}}
