Before the “json” option was introduced, all options were listed. Currently, only the last option is listed. This commit fixes this bug. Options are represented as array. Before: $ ethtool -m sfp-wan ... Option values : 0x00 0x32 Option : RATE_SELECT implemented ... $ ethtool --json -m sfp-wan [ { ... "option_values": [ 0,50 ], "option": "RATE_SELECT implemented", ... } ] After: $ ethtool -m sfp-wan ... Option values : 0x00 0x32 Option : RX_LOS implemented Option : TX_DISABLE implemented Option : RATE_SELECT implemented ... $ ethtool --json -m sfp-wan [ { ... "option_values": [ 0,50 ], "option": [ "RX_LOS implemented","TX_DISABLE implemented","RATE_SELECT implemented" ], ... } ] Fixes: 4071862f58d8 ("sfpid: Add JSON output handling to --module-info in SFF8079 modules") Signed-off-by: Aleksander Jan Bajkowski --- Changes in v3: - fix indentation and checkpatch warnings Changes in v2: - fix typo introduced -> introduced - rename module_print_array_string() -> module_print_any_array_string_entry() --- module-common.c | 8 ++++++++ module-common.h | 1 + sfpid.c | 35 +++++++++++++++++++---------------- 3 files changed, 28 insertions(+), 16 deletions(-) diff --git a/module-common.c b/module-common.c index 42fccf6..43ff649 100644 --- a/module-common.c +++ b/module-common.c @@ -258,6 +258,14 @@ void module_print_any_bool(const char *fn, char *given_json_fn, bool value, printf("\t%-41s : %s\n", fn, str_value); } +void module_print_any_array_string_entry(const char *fn, const char *value) +{ + if (is_json_context()) + print_string(PRINT_JSON, NULL, "%s", value); + else + printf("\t%-41s : %s\n", fn, value); +} + void module_show_value_with_unit(const __u8 *id, unsigned int reg, const char *name, unsigned int mult, const char *unit) diff --git a/module-common.h b/module-common.h index 4063448..f3baf2a 100644 --- a/module-common.h +++ b/module-common.h @@ -281,6 +281,7 @@ void module_print_any_string(const char *fn, const char *value); void module_print_any_float(const char *fn, float value, const char *unit); void module_print_any_bool(const char *fn, char *given_json_fn, bool value, const char *str_value); +void module_print_any_array_string_entry(const char *fn, const char *value); void module_show_value_with_unit(const __u8 *id, unsigned int reg, const char *name, unsigned int mult, const char *unit); diff --git a/sfpid.c b/sfpid.c index 74a6f51..5899f8c 100644 --- a/sfpid.c +++ b/sfpid.c @@ -396,7 +396,6 @@ static void sff8079_show_wavelength_or_copper_compliance(const __u8 *id) static void sff8079_show_options(const __u8 *id) { static const char *pfx = "Option"; - char value[64] = ""; if (is_json_context()) { open_json_array("option_values", ""); @@ -407,35 +406,39 @@ static void sff8079_show_options(const __u8 *id) printf("\t%-41s : 0x%02x 0x%02x\n", "Option values", id[64], id[65]); } + + if (is_json_context()) + open_json_array("option", ""); + if (id[65] & (1 << 1)) - sprintf(value, "%s", "RX_LOS implemented"); + module_print_any_array_string_entry(pfx, "RX_LOS implemented"); if (id[65] & (1 << 2)) - sprintf(value, "%s", "RX_LOS implemented, inverted"); + module_print_any_array_string_entry(pfx, "RX_LOS implemented, inverted"); if (id[65] & (1 << 3)) - sprintf(value, "%s", "TX_FAULT implemented"); + module_print_any_array_string_entry(pfx, "TX_FAULT implemented"); if (id[65] & (1 << 4)) - sprintf(value, "%s", "TX_DISABLE implemented"); + module_print_any_array_string_entry(pfx, "TX_DISABLE implemented"); if (id[65] & (1 << 5)) - sprintf(value, "%s", "RATE_SELECT implemented"); + module_print_any_array_string_entry(pfx, "RATE_SELECT implemented"); if (id[65] & (1 << 6)) - sprintf(value, "%s", "Tunable transmitter technology"); + module_print_any_array_string_entry(pfx, "Tunable transmitter technology"); if (id[65] & (1 << 7)) - sprintf(value, "%s", "Receiver decision threshold implemented"); + module_print_any_array_string_entry(pfx, "Receiver decision threshold implemented"); if (id[64] & (1 << 0)) - sprintf(value, "%s", "Linear receiver output implemented"); + module_print_any_array_string_entry(pfx, "Linear receiver output implemented"); if (id[64] & (1 << 1)) - sprintf(value, "%s", "Power level 2 requirement"); + module_print_any_array_string_entry(pfx, "Power level 2 requirement"); if (id[64] & (1 << 2)) - sprintf(value, "%s", "Cooled transceiver implemented"); + module_print_any_array_string_entry(pfx, "Cooled transceiver implemented"); if (id[64] & (1 << 3)) - sprintf(value, "%s", "Retimer or CDR implemented"); + module_print_any_array_string_entry(pfx, "Retimer or CDR implemented"); if (id[64] & (1 << 4)) - sprintf(value, "%s", "Paging implemented"); + module_print_any_array_string_entry(pfx, "Paging implemented"); if (id[64] & (1 << 5)) - sprintf(value, "%s", "Power level 3 requirement"); + module_print_any_array_string_entry(pfx, "Power level 3 requirement"); - if (value[0] != '\0') - module_print_any_string(pfx, value); + if (is_json_context()) + close_json_array(""); } static void sff8079_show_all_common(const __u8 *id) -- 2.53.0
