From f2a474aea8f82fa9b695515d4590f4f3398358a7 Mon Sep 17 00:00:00 2001 From: Juho Son Date: Thu, 11 Sep 2014 16:06:38 +0900 Subject: journald: add CAP_MAC_OVERRIDE in journald for SMACK issue systemd-journald check the cgroup id to support rate limit option for every messages. so journald should be available to access cgroup node in each process send messages to journald. In system using SMACK, cgroup node in proc is assigned execute label as each process's execute label. so if journald don't want to denied for every process, journald should have all of access rule for all process's label. It's too heavy. so we could give special smack label for journald te get all accesses's permission. '^' label. When assign '^' execute smack label to systemd-journald, systemd-journald need to add CAP_MAC_OVERRIDE capability to get that smack privilege. so I want to notice this information and set default capability to journald whether system use SMACK or not. because that capability affect to only smack enabled kernel --- units/systemd-journald.service.in | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'units') diff --git a/units/systemd-journald.service.in b/units/systemd-journald.service.in index 70139795a5..4de38fad59 100644 --- a/units/systemd-journald.service.in +++ b/units/systemd-journald.service.in @@ -20,7 +20,7 @@ Restart=always RestartSec=0 NotifyAccess=all StandardOutput=null -CapabilityBoundingSet=CAP_SYS_ADMIN CAP_DAC_OVERRIDE CAP_SYS_PTRACE CAP_SYSLOG CAP_AUDIT_CONTROL CAP_CHOWN CAP_DAC_READ_SEARCH CAP_FOWNER CAP_SETUID CAP_SETGID +CapabilityBoundingSet=CAP_SYS_ADMIN CAP_DAC_OVERRIDE CAP_SYS_PTRACE CAP_SYSLOG CAP_AUDIT_CONTROL CAP_CHOWN CAP_DAC_READ_SEARCH CAP_FOWNER CAP_SETUID CAP_SETGID CAP_MAC_OVERRIDE WatchdogSec=1min # Increase the default a bit in order to allow many simultaneous -- cgit v1.2.3-54-g00ecf
