■目前进度
查看logcat发现有相关的tlog权限问题，

05-31 11:30:15.129  3883  3883 I auditd  : type=1400 audit(0.0:293): avc: denied { dac_read_search } for comm="tlogd.sh" capability=2 scontext=u:r:np_thundercomm_tlogdsh:s0 tcontext=u:r:np_thundercomm_tlogdsh:s0 tclass=capability permissive=0

但是有些设备是可以正常抓取ota日志，并且logcat中发现也有这个报错，
怀疑不是这个导致的，并且直接加以上权限会触发neverallow

■下一步计划
对比可以抓取的设备，查看是否有不一样的

#3 Updated by CD SYSTEM-夏旭 about 2 years ago

  • Status changed from New to ASSIGNED

■目前进度
发现版本都无法获取ota日志，并且都有avc报错
userdebug版本setenforce 0，关闭selinux，发现可以获取ota日志
并且有相关报错
05-21 01:01:25.910 4348 4348 I tlogd.sh: type=1400 audit(0.0:224): avc: denied { dac_read_search } for capability=2 scontext=u:r:np_thundercomm_tlogdsh:s0 tcontext=u:r:np_thundercomm_tlogdsh:s0 tclass=capability permissive=1

■下一步计划
添加权限

■目前进度
dac_read_search相关的selinux是加不上的，需要添加相应的group到对应的服务上就可以了
system cache
本地验证OK
■下一步计划
VB验证
