The branch stable/13 has been updated by jhb: URL: https://cgit.FreeBSD.org/src/commit/?id=034af6afc542948b534176a037a990a255ea73f0 commit 034af6afc542948b534176a037a990a255ea73f0 Author: John Baldwin <jhb@FreeBSD.org> AuthorDate: 2022-08-08 18:21:54 +0000 Commit: John Baldwin <jhb@FreeBSD.org> CommitDate: 2022-11-11 00:35:47 +0000 cxgbe: Handle requests for TLS key allocations with no TLS key storage. If an adapter advertises support for TLS keys but an empty TLS key storage area in on-board memory, fail the request rather than invoking vmem_alloc on an uninitialized vmem.
