Change subject: core: fix badly generated macs in db ...................................................................... core: fix badly generated macs in db Note: this patch replaces former one (I4a1b37da30ce4ad6d25c1d510eb5c09e17525f1b) because different approach to fix this issue was requested. There was .py script¹ (now deleted) which was used to generate mac ranges in some circumstances. However there was a bug in it, so some users may end up with MAC address like 00:1a:4a:1:f:ff generated (fourth and fifth group can be formed just by one char). This MAC got without any validation into DB and engine did not detect this problem — since engine code just removes colons and parse value as hex. So in that case user ended up with different mac ranges than intended. In 3.6 code validations were added to UI, where such MAC will fail when user just opens DC edit dialog and confirm it without any change. Because code did not fail, user could continue using such setting, but actually different range was used. For example if generated range was 00:1a:4a:1:f:00-00:1a:4a:1:f:ff, engine actually used range was: 00:00:1a:4a:1f:00-00:00:1a:4a:1f:ff. This patch tries to fix db entries in same way. description of sql udpate: Patch is little bit convoluted because it tries not to use stored procedures. Flow is: • first colons are removed • missing zeroes are added to the left of string to reach total of 12 chars • after each two chars new colon is added; this creates string enging with colon • extra last character is removed.
