為修復如下OpenSSH漏洞，openssh從8.2升級至9.6，然而并未找到統信9.6的rpm源，所以自己動手制作，折騰了一天，在此記錄一下

準備工作

檢查版本

cat /etc/os-releaseuname -a

如圖當前環境為aarch64架構，在其中一臺制作rpm包，之后傳到別的服務器執行安裝即可

rpmbuild構建工具安裝

# 安裝RPM構建工具和依賴
yum install -y rpm-build rpmdevtools wget gcc make zlib-devel openssl-devel pam-devel libXt-devel libX11-devel

設置 RPM 構建環境：

# 創建RPM構建目錄結構
rpmdev-setuptree

下載源碼和準備.spec 文件

# 下載OpenSSH源碼
wget -P ~/rpmbuild/SOURCES https://cdn.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-9.6p1.tar.gz
# 備用，與上面一樣的
wget -P ~/rpmbuild/SOURCES https://mirrors.aliyun.com/pub/OpenBSD/OpenSSH/portable/openssh-9.6p1.tar.gz# 獲取最新的OpenSSH spec文件，這個不一定好使，可以試著自己改一下，下面我提供一個修改好的，可以直接用
wget -O ~/rpmbuild/SPECS/openssh.spec https://src.fedoraproject.org/rpms/openssh/raw/rawhide/f/openssh.spec# 下載x11-ssh-askpass源碼，這個rpm包里是不需要的，但是沒有會報錯
wget -P ~/rpmbuild/SOURCES https://src.fedoraproject.org/repo/pkgs/openssh/x11-ssh-askpass-1.2.4.1.tar.gz

openssh.spec配置修改

vim /root/rpmbuild/SPECS/openssh.spec

主要關注修改版本，禁用no_x11_askpass

新版的openssh源碼里面編譯安裝，已經將ssh-copy-id命令放到了子目錄contrib，但是不會默認安裝，而此命令在使用中比較實用，比如各主機之間的免密認證

install -m755 contrib/ssh-copy-id $RPM_BUILD_ROOT/usr/bin/ssh-copy-id 

%attr(0755,root,root) %{_bindir}/ssh-copy-id

如下為驗證過的統信aarch64架構版本的openssh.spec，可以直接復制使用

vim /root/rpmbuild/SPECS/openssh.spec

SSH (Secure SHell) is a program for logging into and executing
commands on a remote machine. SSH is intended to replace rlogin and
rsh, and to provide secure encrypted communications between two
untrusted hosts over an insecure network. X11 connections and
arbitrary TCP/IP ports can also be forwarded over the secure channel.OpenSSH is OpenBSD's version of the last free version of SSH, bringing
it up to date in terms of security and features, as well as removing
all patented algorithms to separate libraries.
This package includes the core files necessary for both the OpenSSH
client and server. To make this package useful, you should also
install openssh-clients, openssh-server, or both.
%description clients
OpenSSH is a free version of SSH (Secure SHell), a program for logging
into and executing commands on a remote machine. This package includes
the clients necessary to make encrypted connections to SSH servers.
You'll also need to install the openssh package on OpenSSH clients.%description server
OpenSSH is a free version of SSH (Secure SHell), a program for logging
into and executing commands on a remote machine. This package contains
the secure shell daemon (sshd). The sshd daemon allows SSH clients to
securely connect to your SSH server. You also need to have the openssh
package installed.%description askpass
OpenSSH is a free version of SSH (Secure SHell), a program for logging
into and executing commands on a remote machine. This package contains
an X11 passphrase dialog for OpenSSH.%description askpass-gnome
OpenSSH is a free version of SSH (Secure SHell), a program for logging
into and executing commands on a remote machine. This package contains
an X11 passphrase dialog for OpenSSH and the GNOME GUI desktop

構建rpm包

上訴準備工作完成之后，執行如下命令構建rpm包

rpmbuild -ba ~/rpmbuild/SPECS/openssh.spec

看到如下結果為打包成功

進入打包后的rpm包目錄，將相關的包上傳到需要升級的服務器安裝即可

cd /root/rpmbuild/RPMS/aarch64

安裝升級OpenSSH

正常我們安裝openssh-9.6p1-1.uel20.aarch64.rpm、openssh-clients-9.6p1-1.uel20.aarch64.rpm、openssh-server-9.6p1-1.uel20.aarch64.rpm三個包即可，將這三個包上傳至目標服務器進行安裝

scp openssh-9.6p1-1.uel20.aarch64.rpm openssh-clients-9.6p1-1.uel20.aarch64.rpm openssh-server-9.6p1-1.uel20.aarch64.rpm uat90:~/

安裝OpenSSH

注意：安裝前先進行備份，安裝過程如果失敗，容易造成無法再通過ssh連接，建議安裝一個telnet保持長鏈接，同時建議看兩個以上終端連接上再進行升級，以免安裝失敗無法恢復sshd服務正常

停用和卸載舊版本sshd服務

查看當前版本

ssh -Vrpm -qa | grep openssh

卸載

# 停用
systemctl stop sshd
# 卸載當前安裝版本
rpm -e --nodeps openssh-server openssh-clients openssh openssh-help

安裝

注意：安裝前先進行備份，安裝過程如果失敗，容易造成無法再通過ssh連接，建議安裝一個telnet保持長鏈接，同時建議看兩個以上終端連接上再進行升級，以免安裝失敗無法恢復sshd服務正常

rpm -Uvh --oldpackage --nodeps openssh-9.6p1-1.uel20.aarch64.rpm openssh-clients-9.6p1-1.uel20.aarch64.rpm openssh-server-9.6p1-1.uel20.aarch64.rpm

修改配置

vim /etc/ssh/sshd_config

測試配置是否正確?,如下命令如果不報錯則沒有問題

sshd -t

啟動

systemctl start sshdsystemctl status sshd

檢查版本

檢查版本，從其他機器測試登錄是否正常

ssh -V

至此完成統信UOS操作系統aarch64自制OpenSSH的rpm包從8.2p1到9.6p1版本升級

下載rpm資源包安裝

如果你的系統剛好是統信uel20.aarch64，同時OpenSSH是9.6p1以下版本，可以直接下載我編譯好的rpm安裝包
