Also add a new kconfig symbol (CONFIG_KCMP) to the generic config, disabling the SYS_kcmp syscall (it was split from CONFIG_CHECKPOINT_RESTORE, which is disabled by default, so the previous behaviour is kept). Removed (upstreamed) patches: 070-net-icmp-pass-zeroed-opts-from-icmp-v6-_ndo_send-bef.patch 081-wireguard-device-do-not-generate-ICMP-for-non-IP-pac.patch 082-wireguard-queueing-get-rid-of-per-peer-ring-buffers.patch 083-wireguard-kconfig-use-arm-chacha-even-with-no-neon.patch 830-v5.12-0002-usb-serial-option-update-interface-mapping-for-ZTE-P685M.patch Manually rebased patches: 313-helios4-dts-status-led-alias.patch 104-powerpc-mpc85xx-change-P2020RDB-dts-file-for-OpenWRT.patch Run tested: ath79 (TL-WDR3600) mvebu (Turris Omnia) Signed-off-by: Rui Salvaterra <rsalvaterra@gmail.com>

Subject: [PATCH] wireguard: peer: put frequently used members above cache
|
|
lines
|
|
|
|
commit 5a0598695634a6bb4126818902dd9140cd9df8b6 upstream.
|
|
|
|
The is_dead boolean is checked for every single packet, while the
|
|
internal_id member is used basically only for pr_debug messages. So it
|
|
makes sense to hoist up is_dead into some space formerly unused by a
|
|
struct hole, while demoting internal_api to below the lowest struct
|
|
cache line.
