pkts_per_transfer < MAX_PACKETS_PER_TRANSFER = 32. transfer_count < MAX_TRANSFER_COUNT = 16. max_packetsize = maxp * mult. mult <= 3. maxp <= 0x7ff. If all variables have their max value, the result will be bigger that uint16_t. Add an explicit cast.Signed-off-by: Anastasia Belova <abel...@astralinux.ru> --- usbredirhost/usbredirhost.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/usbredirhost/usbredirhost.c b/usbredirhost/usbredirhost.c index 03c56e9..ca19473 100644 --- a/usbredirhost/usbredirhost.c +++ b/usbredirhost/usbredirhost.c @@ -1193,7 +1193,7 @@ static void usbredirhost_stop_stream(struct usbredirhost *host, static void usbredirhost_set_iso_threshold(struct usbredirhost *host, uint8_t pkts_per_transfer, uint8_t transfer_count, uint16_t max_packetsize) { - uint64_t reference = pkts_per_transfer * transfer_count * max_packetsize; + uint64_t reference = (uint64_t)pkts_per_transfer * transfer_count * max_packetsize; host->iso_threshold.lower = reference / 2; host->iso_threshold.higher = reference * 3; DEBUG("higher threshold is %" PRIu64 " bytes | lower threshold is %" PRIu64 " bytes",
