Subject: [PATCH net-next 0/9] atm: remove more dead code
Date: Sat, 13 Jun 2026 13:10:23 -0700 [thread overview]
Message-ID: <20260613201032.77274-1-kuba@kernel.org> (raw)
Commit 6deb53595092 ("net: remove unused ATM protocols and legacy
ATM device drivers") removed a good chunk of old ATM drivers.
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 :/
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
