Hi Linus, Please take this pull request for v6.7-rc4 release. It includes a slight change to fix scarce memory leak. As I noted in pull request for v6.7[1], Linux FireWire subsystem still has an issue of unexpected system reboot in AMD Ryzen machine with a kind of PCI card. Recently I got a help of AMD developer[2] and got some advices to investigate the mechanism of system reboot, but never catch its tail yet... I wish to fix it within the development period for v6.8 kernel. [1] https://lore.kernel.org/lkml/20231105144852.GA165906@workstation.local/ [2] https://lore.kernel.org/lkml/20231128052429.GA25379@workstation.local/ ---------------------------------------------------------------- The following changes since commit 2cc14f52aeb78ce3f29677c2de1f06c0e91471ab: Linux 6.7-rc3 (2023-11-26 19:59:33 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394.git tags/firewire-fixes-6.7-rc4 for you to fetch changes up to 891e0eab32a57fca4d36c5162628eb0bcb1f0edf: firewire: core: fix possible memory leak in create_units() (2023-11-30 09:16:35 +0900) ---------------------------------------------------------------- firewire fixes for 6.7-rc4 This pull request includes a single patch to fix long-standing issue of memory leak at failure of device registration for fw_unit. We rarely encounter the issue, while it should be applied to stable releases, since it fixes inappropriate API usage. ---------------------------------------------------------------- Yang Yingliang (1): firewire: core: fix possible memory leak in create_units() drivers/firewire/core-device.c | 11 ++++------- 1 file changed, 4 insertions(+), 7 deletions(-)

It seems more than just one or two users are hitting this crash and a fix despite all your tremendous efforts it not yet in sight. Hence please allow me to ask: would it cause a significant regression for users of 6.5 and later, if we'd temporarily revert the culprit and anything depending on it until this is solved? Because if not I wonder if we should go down that route, even if it's a drastic measure; but then Greg could fix this in soon in 6.6.y as well. Ciao, Thorsten
