Our goal going forward is to limit the ATM support to PPPoATM used in ADSL deployments. A recent burst of AI generated fixes for net/atm/signaling.c and net/atm/svc.c made me look closer at the remaining code. PPPoATM runs over permanent virtual circuits (PF_ATMPVC) with a statically configured VPI/VCI. We can drop switched virtual circuits (SVCs) and user-space signaling (atmsigd) support. While digging around I noticed a few more obviously dead pieces of code. Annoyingly, I have applied one "fix" to QoS config which will now make net conflict with this series :/ v2: - fix build warning on patch 4 v1: https://lore.kernel.org/20260613201032.77274-1-kuba@kernel.org Jakub Kicinski (9): atm: remove AAL3/4 transport support atm: remove the unused send_oam / push_oam callbacks atm: remove dead SONET PHY ioctls atm: remove the local ATM (NSAP) address registry atm: remove SVC socket support and the signaling daemon interface atm: remove the unused change_qos device operation atm: remove the unused pre_send and send_bh device operations atm: remove unused ATM PHY operations atm: remove orphaned uAPI for deleted drivers, protocols and SVCs net/atm/Makefile | 2 +- include/linux/atm_tcp.h | 24 -- include/linux/atmdev.h | 70 +-- include/uapi/linux/atm_eni.h | 24 -- include/uapi/linux/atm_he.h | 21 - include/uapi/linux/atm_idt77105.h | 29 -- include/uapi/linux/atm_nicstar.h | 54 --- include/uapi/linux/atm_tcp.h | 62 --- include/uapi/linux/atm_zatm.h | 47 -- include/uapi/linux/atmarp.h | 42 -- include/uapi/linux/atmclip.h | 22 - include/uapi/linux/atmdev.h | 18 - include/uapi/linux/atmlec.h | 92 ---- include/uapi/linux/atmmpc.h | 127 ------ include/uapi/linux/atmsvc.h | 56 --- net/atm/addr.h | 21 - net/atm/common.h | 5 - net/atm/protocols.h | 1 - net/atm/signaling.h | 31 -- drivers/atm/solos-pci.c | 4 - net/atm/addr.c | 162 ------- net/atm/atm_sysfs.c | 25 -- net/atm/br2684.c | 3 +- net/atm/common.c | 73 +--- net/atm/ioctl.c | 58 --- net/atm/pppoatm.c | 3 +- net/atm/proc.c | 56 --- net/atm/raw.c | 21 +- net/atm/resources.c | 59 +-- net/atm/signaling.c | 297 ------------- net/atm/svc.c | 695 ------------------------------ 31 files changed, 15 insertions(+), 2189 deletions(-) delete mode 100644 include/linux/atm_tcp.h delete mode 100644 include/uapi/linux/atm_eni.h delete mode 100644 include/uapi/linux/atm_he.h delete mode 100644 include/uapi/linux/atm_idt77105.h delete mode 100644 include/uapi/linux/atm_nicstar.h delete mode 100644 include/uapi/linux/atm_tcp.h delete mode 100644 include/uapi/linux/atm_zatm.h delete mode 100644 include/uapi/linux/atmarp.h delete mode 100644 include/uapi/linux/atmclip.h delete mode 100644 include/uapi/linux/atmlec.h delete mode 100644 include/uapi/linux/atmmpc.h delete mode 100644 include/uapi/linux/atmsvc.h delete mode 100644 net/atm/addr.h delete mode 100644 net/atm/signaling.h delete mode 100644 net/atm/addr.c delete mode 100644 net/atm/signaling.c delete mode 100644 net/atm/svc.c -- 2.54.0
