#406 msg size problem while bridging write FRU commands
Hi,
I finally tracked down another problem for editing/wrinting FRU data.
If I use:
./src/ipmitool -vv -I lanplus -H xxxxxxxxxxxxxx -U user -P user -b 0 -t 0x98 fru write 0 ~/carrier9.bin
(output see below)
It will write the first 8 bytes and then stop (Bug #1). Without Error Message (Bug #2).
Please notice that the second write is 22 Bytes.
if I limit the write size to 13 (or lower) it is working!
(ipmi_fru.c line 455ff)
/ initialize request size only once /
if (fru->max_write_size == 0) {
uint16_t max_rq_size = ipmi_intf_get_max_request_data_size(intf);
What seems to be wrong:
ipmi_intf_get_max_request_data_size() returns 25;
But 16 is the maximum value which works for me.
Not checked how ipmi_intf_get_max_request_data_size get this number (for bridged commands).
Remark: If the supported maximum msg (or payload) size is not detected correctly, this might have impact in other ipmi functions, too.
Cheers,
Bjoern
