Subject: [PATCH] smbios: Add 1 terminator if any string fields defined in
|
|
given table.
|
|
|
|
If user specifies smbios table files through qemu command line, Then will
|
|
get error messages while decoding those table content in guest.
|
|
|
|
Reproducer:
|
|
1. dump a smbios table(say table 1) to a binary file from a pc.
|
|
2. load the binary file through command line: 'qemu -smbios file=...'.
|
|
3. perform 'dmidecode' or 'dmidecode -t 1' in guest.
|
|
|
|
It reports 'Invalid entry length...' because qemu doesn't add terminator(s)
|
|
correctly for the table.
|
|
|
|
This patch fixed the issue by:
|
|
|
|
For smbios tables which have string fields provided, qemu should add 1 terminator.
|
|
For smbios tables which dont have string fields provided, qemu should add 2.
|
