Allocate the LIO port data structures from inside\nsrpt_make_tport() and free these from inside srpt_make_tport(). Keep\nstruct srpt_device as long as either an RDMA port or a LIO target port is\nassociated with it. This patch decouples the lifetime of struct srpt_port\n(controlled by the RDMA core) and struct srpt_port_id (controlled by LIO).\nThis patch fixes the following KASAN complaint:\n\n  BUG: KASAN: use-after-free in srpt_enable_tpg+0x31/0x70 [ib_srpt]\n  Read of size 8 at addr ffff888141cc34b8 by task check/5093\n\n  Call Trace:\n   <TASK>\n   show_stack+0x4e/0x53\n   dump_stack_lvl+0x51/0x66\n   print_address_description.constprop.0.cold+0xea/0x41e\n   print_report.cold+0x90/0x205\n   kasan_report+0xb9/0xf0\n   __asan_load8+0x69/0x90\n   srpt_enable_tpg+0x31/0x70 [ib_srpt]\n   target_fabric_tpg_base_enable_store+0xe2/0x140 [target_core_mod]\n   configfs_write_iter+0x18b/0x210\n   new_sync_write+0x1f2/0x2f0\n   vfs_write+0x3e3/0x540\n   ksys_write+0xbb/0x140\n   __x64_sys_write+0x42/0x50\n   do_syscall_64+0x34/0x80\n   entry_SYSCALL_64_after_hwframe+0x46/0xb0\n   </TASK>"}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/infiniband/ulp/srpt/ib_srpt.c","drivers/infiniband/ulp/srpt/ib_srpt.h"],"versions":[{"version":"a42d985bd5b234da8b61347a78dc3057bf7bb94d","lessThan":"de95b52d9aabc979166aba81ccbe623aaf9c16a1","status":"affected","versionType":"git"},{"version":"a42d985bd5b234da8b61347a78dc3057bf7bb94d","lessThan":"e60d7e2462bf57273563c4e00dbfa79ee973b9e2","status":"affected","versionType":"git"},{"version":"a42d985bd5b234da8b61347a78dc3057bf7bb94d","lessThan":"4ee8c39968a648d58b273582d4b021044a41ee5e","status":"affected","versionType":"git"},{"version":"a42d985bd5b234da8b61347a78dc3057bf7bb94d","lessThan":"388326bb1c32fcd09371c1d494af71471ef3a04b","status":"affected","versionType":"git"},{"version":"a42d985bd5b234da8b61347a78dc3057bf7bb94d","lessThan":"b5605148e6ce36bb21020d49010b617693933128","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/infiniband/ulp/srpt/ib_srpt.c","drivers/infiniband/ulp/srpt/ib_srpt.h"],"versions":[{"version":"3.3","status":"affected"},{"version":"0","lessThan":"3.3","status":"unaffected","versionType":"semver"},{"version":"5.10.137","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.61","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"5.18.18","lessThanOrEqual":"5.18.*","status":"unaffected","versionType":"semver"},{"version":"5.19.2","lessThanOrEqual":"5.19.*","status":"unaffected","versionType":"semver"},{"version":"6.0","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":"3.3","versionEndExcluding":"5.10.137"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.3","versionEndExcluding":"5.15.61"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.3","versionEndExcluding":"5.18.18"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.3","versionEndExcluding":"5.19.2"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.3","versionEndExcluding":"6.0"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/de95b52d9aabc979166aba81ccbe623aaf9c16a1"},{"url":"https://git.kernel.org/stable/c/e60d7e2462bf57273563c4e00dbfa79ee973b9e2"},{"url":"https://git.kernel.org/stable/c/4ee8c39968a648d58b273582d4b021044a41ee5e"},{"url":"https://git.kernel.org/stable/c/388326bb1c32fcd09371c1d494af71471ef3a04b"},{"url":"https://git.kernel.org/stable/c/b5605148e6ce36bb21020d49010b617693933128"}],"title":"RDMA/srpt: Fix a use-after-free","x_generator":{"engine":"bippy-1.2.0"}}}}
