Bug#1023958: Request to enable CONFIG_AF_KCM
Package: src:linux Version: 6.0.8-1 Severity: wishlist It has been 6 years (since Linux kernel v4.10) that upstream introduced a rather useful feature for protocols implementing binary message based protocols on top of TCP called KCM. Unfortunately during all those years and even until Debian unstable today, it is not possible to use this feature as the kernels are compiled with CONFIG_AF_KCM disabled. This creates a rather unfortunate chicken-and-egg situation where there are userspace programs/libraries that would benefit from its related performance, but cannot use it with unmodified Debian kernels and hence are less motivated to enable it. So lack of distribution support hinders adoption by more applications. Background on KCM can be found at https://lwn.net/Articles/657999/ and in the kernel source at Documentation/networking/kcm.rst I would hence like to request enabling CONFIG_AF_KCM in the Debian kernel packages. Since STREAM_PARSER and BPF_SYSCALL are both already enabled, there are no additional dependencies. AF_KCM can be built as module, so it should not affect any systems where no applications use it. It would only be auto-loaded once an AF_KCM socket is being used for the first time. Thanks for your consideration. -- Package-specific info: ** Kernel log: boot messages should be attached -- System Information: Debian Release: bookworm/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.19.0-2-amd64 (SMP w/4 CPU threads; PREEMPT) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages linux-image-6.0.0-4-amd64 depends on: it initramfs-tools [linux-initramfs-tool] 0.142 ii kmod30+20220905-1 ii linux-base 4.9 Versions of packages linux-image-6.0.0-4-amd64 recommends: iu apparmor 3.0.7-1+b2 ii firmware-linux-free 20200122-1 Versions of packages linux-image-6.0.0-4-amd64 suggests: pn debian-kernel-handbook ii extlinux3:6.04~git20190206.bf6db5b4+dfsg1-3+b1 ii grub-pc 2.06-4 pn linux-doc-6.0 Versions of packages linux-image-6.0.0-4-amd64 is related to: pn firmware-amd-graphics pn firmware-atheros pn firmware-bnx2 pn firmware-bnx2x pn firmware-brcm80211 pn firmware-cavium pn firmware-intel-sound pn firmware-intelwimax pn firmware-ipw2x00 pn firmware-ivtv ii firmware-iwlwifi 20221012-1 pn firmware-libertas pn firmware-linux-nonfree ii firmware-misc-nonfree 20221012-1 pn firmware-myricom pn firmware-netxen pn firmware-qlogic pn firmware-realtek pn firmware-samsung pn firmware-siano pn firmware-ti-connectivity pn xen-hypervisor -- no debconf information

Bug#846913: Acknowledgement (CONFIG_GTP is not set / gtp.ko module not built)
Not that this would have any significance to Debian, but just for your information, the latest Fedora, OpenSUSE and Ubuntu releases (shipping 4.8.0 or later) have all enabled CONFIG_GTP. It would be great if people (myself included) could run their GTP-using software also on Debian :) Regards, Harald -- - Harald Welte <lafo...@gnumonks.org> http://laforge.gnumonks.org/ "Privacy in residential applications is a desirable marketing option."

Bug#846913: CONFIG_GTP is not set / gtp.ko module not built
Package: src:linux Version: 4.8.7-1 Severity: wishlist Dear Debian kernel team, it would be great if you could activate the (newly-introduced) CONFIG_GTP kernel option to build the related kernel module. The Module implements the 3GPP GTP (Generic Tunneling Protocol) and has no impact on any other parts of the kernel or networking sub-system, except that one addtiional tunneling protocol is present, which some users might use and others not. There are several Free Software userspace programs using the GTP module, including OpenGGSN, ergw and OpenAirInterface.

Bug#798375: Stale SCTP sockets / recovery only by reboot
Package: src:linux Version: 3.16.5-1 Severity: normal Tags: patch I appear to have run into a SCTP bug that has been around since 2009: http://sourceforge.net/p/lksctp/mailman/message/23492403/ and has been fixed in mainline as part of commit bdf6fa52f01b941d4a80372d56de465bdbbd1d23. However, the bug was still visible in the Debian kernel version 3.16.5-1, and I suppose all that's needed is a cherry-pick. It is possible to reproduce as follows: * start a SCTP server socket (bind/listen) on linux * make the client connect to that * accept() the connection on the server * make the client disappear suddenly (e.g. power it down, disconnect its network cable) in a way that there is no handshake to terminate the association * close the server program ** linux sends SHUTDOWN and associated retansmissions * start the server program again * make the client re-connect ** INIT/INIT_ACK/HEARTBEAT/HEARTBEAT_ACK/DT1/SACK messages can be seen in wireshark on the server and traverse nicely to and from the client, but none of that data ever arrives on th socket. The re-started server never even receives any notification about the new connection, thre is subequently no socket being created. I double-checked, no other process had a clone of that socket open from the userspace point of view. The only way I fould to recover was to reboot the server system, which of course is quite annoying. Unloading the sctp kernel module was not an option, as it still had a reference count, despite no SCTP sockets existing anymore in the system. The issue was possible to reproduce several times, so itw as not some strange one-off behavior. -- Package-specific info: ** Version: Linux version 3.16-3-amd64 (debian-kernel@lists.debian.org) (gcc version 4.8.3 (Debian 4.8.3-12) ) #1 SMP Debian 3.16.5-1 (2014-10-10) ** Command line: BOOT_IMAGE=/boot/vmlinuz-3.16-3-amd64 root=UUID=2fa8d876-a03f-447f-bda0-d7f6fed53004 ro ** Not tainted -- System Information: Debian Release: stretch/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.16-3-amd64 (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Init: systemd (via /run/systemd/system) Versions of packages linux-image-3.16-3-amd64 depends on: ii debconf [debconf-2.0] 1.5.57 ii initramfs-tools [linux-initramfs-tool] 0.120 ii kmod21-1 ii linux-base 4.0 ii module-init-tools 21-1 Versions of packages linux-image-3.16-3-amd64 recommends: ii firmware-linux-free 3.4 Versions of packages linux-image-3.16-3-amd64 suggests: pn debian-kernel-handbook ii extlinux3:6.03+dfsg-10 ii grub-pc 2.02~beta2-26 pn linux-doc-3.16 Versions of packages linux-image-3.16-3-amd64 is related to: pn firmware-atheros pn firmware-bnx2 pn firmware-bnx2x pn firmware-brcm80211 pn firmware-intelwimax pn firmware-ipw2x00 pn firmware-ivtv ii firmware-iwlwifi0.44 pn firmware-libertas pn firmware-linux pn firmware-linux-nonfree pn firmware-myricom pn firmware-netxen pn firmware-qlogic ii firmware-ralink 0.44 pn firmware-realtek pn xen-hypervisor -- debconf information: linux-image-3.16-3-amd64/postinst/depmod-error-initrd-3.16-3-amd64: false linux-image-3.16-3-amd64/prerm/removing-running-kernel-3.16-3-amd64: true linux-image-3.16-3-amd64/postinst/mips-initrd-3.16-3-amd64:
