random_ether_addr() is finally removed in kernel commit ba530fea8ca1
("ethernet: remove random_ether_addr()"). Backport commit e6cbfd9bf30b
("kni: update kernel API to set random MAC address") from dpdk repo
to use eth_random_addr() instead.Signed-off-by: Yongxin Liu <[email protected]> --- recipes-extended/dpdk/dpdk-module_20.11.1.bb | 1 + ...kernel-API-to-set-random-MAC-address.patch | 44 +++++++++++++++++++ 2 files changed, 45 insertions(+) create mode 100644 recipes-extended/dpdk/dpdk/0002-kni-update-kernel-API-to-set-random-MAC-address.patch diff --git a/recipes-extended/dpdk/dpdk-module_20.11.1.bb b/recipes-extended/dpdk/dpdk-module_20.11.1.bb index 1860087..85d708c 100644 --- a/recipes-extended/dpdk/dpdk-module_20.11.1.bb +++ b/recipes-extended/dpdk/dpdk-module_20.11.1.bb @@ -4,6 +4,7 @@ FILESEXTRAPATHS:prepend := "${THISDIR}/dpdk:" SRC_URI += " \ file://0001-Makefile-add-makefile.patch \ + file://0002-kni-update-kernel-API-to-set-random-MAC-address.patch \ " STABLE = "-stable" BRANCH = "20.11" diff --git a/recipes-extended/dpdk/dpdk/0002-kni-update-kernel-API-to-set-random-MAC-address.patch b/recipes-extended/dpdk/dpdk/0002-kni-update-kernel-API-to-set-random-MAC-address.patch new file mode 100644 index 0000000..dea9e12 --- /dev/null +++ b/recipes-extended/dpdk/dpdk/0002-kni-update-kernel-API-to-set-random-MAC-address.patch @@ -0,0 +1,44 @@ +From e0a23f3cf8410871d28fdd8f0806216848b357ce Mon Sep 17 00:00:00 2001 +From: Ferruh Yigit <[email protected]> +Date: Wed, 3 Nov 2021 12:59:50 +0000 +Subject: [PATCH] kni: update kernel API to set random MAC address + +Previously used 'random_ether_addr()' API is removed in upstream kernel +with commit +Commit ba530fea8ca1 ("ethernet: remove random_ether_addr()") + +Replacement API 'eth_random_addr()' is around since v3.6 [1], so +simply switching to this API without any version checks. + +[1] +0a4dd594982a ("etherdevice: Rename random_ether_addr to eth_random_addr") + +Signed-off-by: Ferruh Yigit <[email protected]> + +Upstream-Status: Backport [http://git.dpdk.org/dpdk/commit/?id=e6cbfd9bf30bbc4170fe8c7c04a16d9cf795fb90] +Signed-off-by: Yongxin Liu <[email protected]> +--- + kernel/linux/kni/kni_misc.c | 7 ++----- + 1 file changed, 2 insertions(+), 5 deletions(-) + +diff --git a/kernel/linux/kni/kni_misc.c b/kernel/linux/kni/kni_misc.c +index 2b464c4381..f4944e1ddf 100644 +--- a/kernel/linux/kni/kni_misc.c ++++ b/kernel/linux/kni/kni_misc.c +@@ -399,11 +399,8 @@ kni_ioctl_create(struct net *net, uint32_t ioctl_num, + if (is_valid_ether_addr(dev_info.mac_addr)) + memcpy(net_dev->dev_addr, dev_info.mac_addr, ETH_ALEN); + else +- /* +- * Generate random mac address. eth_random_addr() is the +- * newer version of generating mac address in kernel. +- */ +- random_ether_addr(net_dev->dev_addr); ++ /* Generate random MAC address. */ ++ eth_random_addr(net_dev->dev_addr); + + if (dev_info.mtu) + net_dev->mtu = dev_info.mtu; +-- +2.32.0 + -- 2.31.1
