kernel: add missing dependency to KERNEL_RPI_AXIPERF

2022-12-18T10:21:19Z

This symbol is added by the bcm27xx target patches so it should depend on that target. Fixes: efd9463dcfe2 ("kernel: add missing symbol for bcm27xx") Signed-off-by: Stijn Tintel (cherry picked from commit d5dc6cdc536277ce1831acce92dc1cbdc59e7250)

kernel: add missing symbol for bcm27xx

2022-12-18T10:20:45Z

When KERNEL_PERF_EVENTS is enabled in OpenWrt, the RPI_AXIPERF symbol is exposed. Add a build option for it to fix build failures with KERNEL_PERF_EVENTS enabled. Fixes: 3564c22e46d5 ("bcm27xx: disable duplicate sdhost driver") Signed-off-by: Stijn Tintel (cherry picked from commit efd9463dcfe27681879d18e5fd9a32351447aa25)

toolchain: Select USE_SSTRIP with external musl toolchain

2022-10-03T17:51:49Z

When we use the internal toolchain USE_SSTRIP will be selected by default for musl libc and USE_STRIP when glibc is used. Do the same when an external toolchain is used. USE_GLIBC will also be set for external toolchain builds based on the EXTERNAL_TOOLCHAIN_LIBC_USE_GLIBC setting.

kernel: add missing symbol

2022-09-22T17:19:43Z

Enabling KERNEL_KPROBES exposes KERNEL_BPF_KPROBE_OVERRIDE. Add a build option for it to fix build failures with KERNEL_KPROBES enabled. Signed-off-by: Stijn Tintel (cherry picked from commit 500c37c56ff60b46c30bb0ea7c92676bea23331a)

scripts: always check certificates

2022-09-16T16:50:46Z

Remove flags from wget and curl instructing them to ignore bad server certificates. Although other mechanisms can protect against malicious modifications of downloads, other vectors of attack may be available to an adversary. TLS certificate verification can be disabled by turning oof the "Enable TLS certificate verification during package download" option enabled by default in the "Global build settings" in "make menuconfig" Signed-off-by: Josh Roys [ add additional info on how to disable this option ] Signed-off-by: Christian Marangi (cherry picked from commit 90c6e3aedf167b0ae1baf376e7800a631681e69a)

bcm53xx: use -falign-functions=32 for kernel compilation

2022-07-08T11:02:39Z

Northstar SoCs have pretty small CPU caches and their performance is heavily affected by cache hits & misses. It means that all kind of random code changes can affect performance as they often reorganize (change alignment & possibly reorder) kernel symbols. It was discussed in ARM / net mailinglists: 1. ARM router NAT performance affected by random/unrelated commits [1] [2] 2. Optimizing kernel compilation / alignments for network performance [3] [4] It seems that -falign-functions can be used as a partial workaround. It doesn't solve all cases (e.g. documented watchdog one [5]) but it surely helps with many of them. A complete long term solution may be PGO (profile-guided optimization) but it isn't available at this point.

kernel: add kmod-vrf

2022-02-01T21:59:09Z

Add option to compile kmod-vrf, support for Virtual Routing and Forwarding (Lite). This module depends on NET_L3_MASTER_DEV, which is a boolean kernel option, so we need to create a configuration option also for this, and make kmod-vrf depend on it. Signed-off-by: Marek Behún
