From d6d4ad0663dc91a448139d9bac4fecab43a41b30 Mon Sep 17 00:00:00 2001 From: Elliott Hughes Date: Tue, 24 Mar 2015 14:17:03 -0500 Subject: [PATCH] Implement load_policy. Note that this is a case where Android's tool isn't the same as the usual tool. Ours takes an explicit file containing the policy to be loaded. restorecon is at least command-line compatible, but the implementation is all in Android's libselinux where there's a selinux_android_restorecon function. --- toys/pending/load_policy.c | 41 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) create mode 100644 toys/pending/load_policy.c diff --git a/toys/pending/load_policy.c b/toys/pending/load_policy.c new file mode 100644 index 0000000..ffe113e --- /dev/null +++ b/toys/pending/load_policy.c @@ -0,0 +1,41 @@ +/* runcon.c - Run command in specified security context + * + * Copyright 2015 The Android Open Source Project + +USE_LOAD_POLICY(NEWTOY(load_policy, "<1>1", TOYFLAG_USR|TOYFLAG_SBIN)) + +config LOAD_POLICY + bool "load_policy" + depends on TOYBOX_SELINUX + default n + help + usage: load_policy FILE + + Load the specified policy file. +*/ + +#define FOR_load_policy +#include "toys.h" + +void load_policy_main(void) +{ + char *path = *toys.optargs; + char *policy_data = 0; + off_t policy_len; + int fd; + + if ((fd = open(path, O_RDONLY)) != -1) { + policy_len = fdlength(fd); + policy_data = mmap(0, policy_len, PROT_READ, MAP_PRIVATE, fd, 0); + close(fd); + } + + if (!policy_data) { + error_exit("Couldn't read %s: %s", path, strerror(errno)); + } + + if (security_load_policy(policy_data, policy_len) < 0) + error_exit("Couldn't load %s: %s", path, strerror(errno)); + + munmap(policy_data, policy_len); +} -- 2.7.4
