Zhenlei Huang 5be5d0d5cb geom_part: Check number of GPT entries and size of GPT entry ... Current specification does not have upper limit of the number of partition entries and the size of partition entry. In 799eac8c3d Andrey V. Elsukov introduced a limit maximum number of GPT entries to 4k, but that is for write routine (gpart create) only. When attaching disks that have large number of GPT entries exceeding the limit, or disks with large size of partition entry, it is still possible to exhaust kernel memory. 1. Reuse the limit of the maximum number of partition entries. 2. Limit the maximum size of GPT entry to 1k. In current specification (2.10) the size of GPT entry is 128 * 2^n while n >= 0, and the size - 128 is reserved. 1k should be sufficient enough for foreseen future.
