dovecot/core-2.2: src/lib/net.c annotate

annotate src/lib/net.c @ 21322:5ab8dc1a4a6f

global: Change string position/length from unsigned int to size_t Mainly to avoid truncating >4GB strings, which might potentially cause some security holes. Normally there are other limits, which prevent such excessive strings from being created in the first place. I'm sure this didn't find everything. Maybe everything could be found with compiler warnings. -Wconversion kind of does it, but it gives way too many unnecessary warnings. These were mainly found with: grep " = strlen" egrep "unsigned int.*(size|len)"
