Package: openssh-client
Version: 1:4.6p1-5
Severity: normal

Hi,

Without a running ControlMaster, I get this desired behaviour:

$ ssh nomeata.de echo test \; sleep 10
prints “test”, waits for 10 seconds and returns to the prompt

$ ssh -f nomeata.de echo test \; sleep 10
waits for the connection to establish and then returns to the prompt.
Then “test” is written across it, and the process sits in the background
for 10 seconds.

If I have a control master for the host running, both ways to run the
command bevahe as the first: Even with “-f” ssh is not going to the
background.

I assume that the point at which -f takes effect is part of the
connection opening code that can be skipped if a ControlMaster is
present.

Greetings,
Joachim

Changes:
 openssh (1:9.4p1-1) unstable; urgency=medium
 .
   * New upstream release (https://www.openssh.com/releasenotes.html#9.4p1):
     - ssh-agent(1): PKCS#11 modules must now be specified by their full
       paths. Previously dlopen(3) could search for them in system library
       directories.
     - ssh(1): allow forwarding Unix Domain sockets via ssh -W.
     - ssh(1): add support for configuration tags to ssh(1). This adds a
       ssh_config(5) "Tag" directive and corresponding "Match tag" predicate
       that may be used to select blocks of configuration similar to the
       pf.conf(5) keywords of the same name.
     - ssh(1): add a "match localnetwork" predicate. This allows matching on
       the addresses of available network interfaces and may be used to vary
       the effective client configuration based on network location.
     - ssh(1), sshd(8), ssh-keygen(1): infrastructure support for KRL
       extensions. This defines wire formats for optional KRL extensions and
       implements parsing of the new submessages. No actual extensions are
       supported at this point.
     - sshd(8): AuthorizedPrincipalsCommand and AuthorizedKeysCommand now
       accept two additional %-expansion sequences: %D which expands to the
       routing domain of the connected session and %C which expands to the
       addresses and port numbers for the source and destination of the
       connection.
     - ssh-keygen(1): increase the default work factor (rounds) for the
       bcrypt KDF used to derive symmetric encryption keys for passphrase
       protected key files by 50%.
     - ssh-agent(1): improve isolation between loaded PKCS#11 modules by
       running separate ssh-pkcs11-helpers for each loaded provider.
     - ssh(1): make -f (fork after authentication) work correctly with
       multiplexed connections, including ControlPersist (closes: #348741).
     - ssh(1): make ConnectTimeout apply to multiplexing sockets and not just
       to network connections.
     - ssh-agent(1), ssh(1): improve defences against invalid PKCS#11 modules
       being loaded by checking that the requested module contains the
       required symbol before loading it.
     - sshd(8): fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand
       appears before it in sshd_config. Since OpenSSH 8.7 the
       AuthorizedPrincipalsCommand directive was incorrectly ignored in this
       situation.
     - sshd(8), ssh(1), ssh-keygen(1): remove vestigial support for KRL
       signatures. When the KRL format was originally defined, it included
       support for signing of KRL objects. However, the code to sign KRLs and
       verify KRL signatues was never completed in OpenSSH. This release
       removes the partially-implemented code to verify KRLs. All OpenSSH
       tools now ignore KRL_SECTION_SIGNATURE sections in KRL files.
     - All: fix a number of memory leaks and unreachable/harmless integer
       overflows.
     - ssh-agent(1), ssh(1): don't truncate strings logged from PKCS#11
       modules.
     - sshd(8), ssh(1): better validate CASignatureAlgorithms in ssh_config
       and sshd_config. Previously this directive would accept certificate
       algorithm names, but these were unusable in practice as OpenSSH does
       not support CA chains.
     - ssh(1): make `ssh -Q CASignatureAlgorithms` only list signature
       algorithms that are valid for CA signing. Previous behaviour was to
       list all signing algorithms, including certificate algorithms.
     - ssh-keyscan(1): gracefully handle systems where rlimits or the maximum
       number of open files is larger than INT_MAX.
     - ssh-keygen(1): fix "no comment" not showing on when running
       `ssh-keygen -l` on multiple keys where one has a comment and other
       following keys do not. bz3580
     - scp(1), sftp(1): adjust ftruncate() logic to handle servers that
       reorder requests. Previously, if the server reordered requests then
       the resultant file would be erroneously truncated.
     - ssh(1): don't incorrectly disable hostname canonicalization when
       CanonicalizeHostname=yes and ProxyJump was explicitly set to "none".
     - scp(1): when copying local->remote, check that the source file exists
       before opening an SFTP connection to the server (closes: #59255).
     - sshd(8): provide a replacement for the SELinux matchpathcon()
       function, which is deprecated.
     - All: relax libcrypto version checks for OpenSSL >=3 (closes:
       #1035623). Beyond OpenSSL 3.0, the ABI compatibility guarantees are
       wider (only the library major must match instead of major and minor in
       earlier versions).
     - ssh-copy-id(1): Special case OpenWrt instead of Dropbear
       (LP: #1966886).
