* Only use host_get_kernel_version and default_pager_paging_storage_new in x86_64.Flavio Cruz2023-05-111-7/+23
| | | | | | | | | | Also fixed the implementation of default_pager_paging_storage_new in proxy def pager to call into default_pager_paging_storage_new. We can fast track the simplification of the RPC ABI for x86_64 if we don't have MACH_MSG_TYPE_STRING used in RPCs which forces msgt_size to use more than 8 bits.

* Use c_string for default_pager_filename_t to define a new ↵Flavio Cruz2023-04-251-0/+11
| | | | | | | | | | default_pager_paging_storage RPC. This brings us a bit closer to having all types' msgt_size representable with a single byte. We will be able to avoid mach_msg_type_long_t entirely for x86_64 since mach_msg_type_t can represent long types using a separate field. Message-Id: <ZEdO0Grm2AUw4Tfe@jupiter.tail36e24.ts.net>
* Remove default_pager_paging_file RPC from default pagerFlavio Cruz2023-04-151-12/+0
| | | | | | | | | The default_pager_paging_storage RPC has already it more than 20 years ago. Given that we want to change the type of default_pager_filename_t to use c_string, we can just remove the unused RPC. Tested that swapon/swapoff still work with the new binaries.

* trans/proxy-defpager: convert to trivfs dynamic classes and bucketsJustus Winter2015-09-271-3/+10
| | | | | | | | | | | | | | | | | | | | libtrivfs contains two ways of managing more than one port class and bucket. There is the old way of using a statically allocated array with explicit length, and the new way with dynamically allocated vectors. Converting all users to the new way of handling multiple classes and/or buckets, we can simplify the code in libtrivfs. In many cases, the code will be simpler and more expressive for the user. This also fixes a severe bug. As no classes are given to `trivfs_startup', they are created and inserted into the dynamic vector of classes. The helper function `allowed', however, used the first item of the previously used static array, which is NULL. This circumvented the typecheck, allowing the default pager protocol to be spoken over control ports, likely resulting in a crash. * trans/proxy-defpager.c: Convert to dynamic classes and buckets.
