Colon is not allowed in strings and breaks nft -f. So move to quoted string in selctx output. Before patch: # nft list ruleset > rules.nft; cat rules.nft table inet t { secmark s { system_u:object_r:ssh_server_packet_t:s0 } } # nft flush ruleset # nft -f rules.nft rules.nft:3:11-11: Error: syntax error, unexpected colon system_u:object_r:ssh_server_packet_t:s0 ^ After patch: # nft list ruleset > rules.nft; cat rules.nft table inet t { secmark s { "system_u:object_r:ssh_server_packet_t:s0" } } # nft flush ruleset # nft -f rules.nft Fixes: 3bc84e5c ("src: add support for setting secmark") Signed-off-by: Eric Jallot <ejallot@xxxxxxxxx> --- src/rule.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/rule.c b/src/rule.c index 255fe37..e4aee9d 100644 --- a/src/rule.c +++ b/src/rule.c @@ -1820,7 +1820,7 @@ static void obj_print_data(const struct obj *obj, if (nft_output_handle(octx)) nft_print(octx, " # handle %" PRIu64, obj->handle.handle.id); nft_print(octx, "%s%s%s", opts->nl, opts->tab, opts->tab); - nft_print(octx, "%s", obj->secmark.ctx); + nft_print(octx, "\"%s\"", obj->secmark.ctx); nft_print(octx, "%s", opts->nl); break; case NFT_OBJECT_CT_HELPER: -- 1.8.3.1
