[OpenWrt-Devel] Bumping net/wireless it s buggy ! 5.3-rc4-1 => 5.3 ( rc9) ?

Mon Sep 16 14:10:42 EDT 2019

Dear openWRT gurus,

the patch : https://github.com/torvalds/linux/commit/b67fd72e84a88cae64cea8ab47ccdaab3bb3094d#diff-35454f3f0395271a0e34581e160bea5f

Is missing from my build :
./build_dir/target-arm_cortex-a7+neon-vfpv4_musl_eabi/linux-ipq40xx_generic/backports-5.3-rc4-1

# cat  /etc/openwrt_release
DISTRIB_ID='OpenWrt'
DISTRIB_RELEASE='SNAPSHOT'
DISTRIB_REVISION='r10985-4364dd244c'
DISTRIB_TARGET='ipq40xx/generic'
DISTRIB_ARCH='arm_cortex-a7_neon-vfpv4'
DISTRIB_DESCRIPTION='OpenWrt SNAPSHOT r10985-4364dd244c'
DISTRIB_TAINTS='no-all busybox'

I tried to catch up the last commits, but it breaks my release.
Moreover, util.c exploded ( trace below)

I do not know where backports-5.3-rc4-1 is inserted in linux-ipq, so I
cannot check if it was updated on your side with my missing commit to
be current.
Moreover I am not sure if this bug should be reported upstream on
linux ASM or some nl80211 mailing list.

Would it be possible to backport 5.3 that was release 22 hours ago
over the 4.19 ? how to test it ? ( IE where is this backport copied /
used )

Please advise.
