The branch stable/13 has been updated by zlei: URL: https://cgit.FreeBSD.org/src/commit/?id=a948a61a822f82a99ac58a412621e5546eac6be3 commit a948a61a822f82a99ac58a412621e5546eac6be3 Author: Zhenlei Huang <zlei@FreeBSD.org> AuthorDate: 2024-07-16 15:53:18 +0000 Commit: Zhenlei Huang <zlei@FreeBSD.org> CommitDate: 2024-07-16 15:53:18 +0000 if_vxlan(4): Move the allocating of statistics counters below if_alloc() The MFS of the fix [1] is done but the prerequisite [2] has not been MFCed to stable/13 branch yet. This results in another potential leak condition in stable/13 branch. Well `if_alloc(IFT_ETHER)` shall not fail, but just in case. This is a direct commit to stable/13. 1. e729e750806d if_vxlan(4): Plug a memory leak 2. 4787572d0580 ifnet: make if_alloc_domain() never fail Reviewed by: kp Fixes: 12bd1341d2aa if_vxlan(4): Plug a memory leak Differential Revision: https://reviews.freebsd.org/D45972 --- sys/net/if_vxlan.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/sys/net/if_vxlan.c b/sys/net/if_vxlan.c index 2cc9f60cba87..3c074952864c 100644 --- a/sys/net/if_vxlan.c +++ b/sys/net/if_vxlan.c @@ -3216,13 +3216,13 @@ vxlan_clone_create(struct if_clone *ifc, int unit, caddr_t params) goto fail; } - vxlan_stats_alloc(sc); ifp = if_alloc(IFT_ETHER); if (ifp == NULL) { error = ENOSPC; goto fail; } + vxlan_stats_alloc(sc); sc->vxl_ifp = ifp; rm_init(&sc->vxl_lock, "vxlanrm"); callout_init_rw(&sc->vxl_callout, &sc->vxl_lock, 0);
