--- Comment #10 from Darren Tucker <[email protected]> --- Given there's a reproducer and a relatively small range of changes, I bisected it down to one of the following (the SIGINFO changes don't compile until the ifdef wrapping): There are only 'skip'ped commits left to test. The first bad commit could be any of: dc5147028ff19213a32281dad07bba02e58da3fa 289239046b2c4b0076c14394ae9703a879e78706 f807a598c96be683d97810481e954ec9db6b0027 b7ee13fbbb4ebafcf71f29685f053ecb97d1bcef We cannot bisect more! commit b7ee13fbbb4ebafcf71f29685f053ecb97d1bcef Author: Damien Miller <[email protected]> Date: Mon Aug 18 14:22:18 2025 +1000 wrap SIGINFO in ifdef commit 289239046b2c4b0076c14394ae9703a879e78706 (HEAD) Author: [email protected] <[email protected]> Date: Mon Aug 18 03:43:01 2025 +0000 upstream: Make ssh(1) and sshd(8) set IP QoS (aka IP_TOS, IPV6_TCLASS) continually at runtime based on what sessions/channels are open. Previously, ssh(1) and sshd(8) would pick a QoS value when they were started and use it for the whole connection. This could produce suboptimal choices for the QoS value, e.g. for multiplexed sessions that started interactive but picked up a sftp client, or sessions that moved large amounts of data via port forwarding. Now the QoS value will change to the non-interactive IPQoS whenever a "non-interactive" channel is open; basically any channel that lacks a tty other than agent forwarding. This is important now that the default interactive IPQoS is EF (Expedited Forwarding), as many networks are configured to allow only relatively small amounts of traffic of this class and they will aggressively deprioritise the entire connection if this is exceeded. NB. because ssh(1) and sshd(8) now change IP_TOS/IPV6_TCLASS continually via setsockopt(), this commit requires a recent pledge(2) change that landed recently in the OpenBSD kernel. Please ensure you have updated to a kernel from within the last two weeks before updating OpenSSH. with job@ deraadt@ OpenBSD-Commit-ID: 325fc41717eecdf5e4b534bfa8d66817425b840f commit dc5147028ff19213a32281dad07bba02e58da3fa Author: [email protected] <[email protected]> Date: Mon Aug 18 03:29:11 2025 +0000 upstream: SIGINFO handler for sshd(8) to dump active channels/sessions ok deraadt@ OpenBSD-Commit-ID: 9955cb6d157c6d7aa23a819e8ef61b1edabc8b7d commit f807a598c96be683d97810481e954ec9db6b0027 Author: [email protected] <[email protected]> Date: Mon Aug 18 03:28:36 2025 +0000 upstream: SIGINFO handler for ssh(1) to dump active channels/sessions ok deraadt@ OpenBSD-Commit-ID: 12f88a5044bca40ef5f41ff61b1755d0e25df901 -- You are receiving this mail because: You are watching the assignee of the bug.
