When buffer reallocation occurs in HTTP/1.1 connections, parsed header references become invalid since they point to locations in the old buffer. This causes memory corruption and crashes when later accessing those headers. Add splunk_conn_realloc_and_reparse() function that: - Performs buffer reallocation - Resets parser state - Reinitializes HTTP session and request This ensures no dangling pointers exist after reallocation, preventing crashes at the cost of reparsing. A proper fix using offsets instead of pointers will be implemented in mk_http_parser in a future change. Fixes #9964 Signed-off-by: Jorge Niedbalski <[email protected]>
