2025-02-09Restring default_pager_paging_storage to i386Samuel Thibault
Newer ports won't have it either.
2025-02-08Add names to threadsSamuel Thibault
2024-12-29fifo: Do not detach pipe when there are still readersSamuel Thibault
Typically for a control socket we need to be able to connect several times to it. This notably fixes the control socket of sv.

2023-08-08Get rid of u_int in RPCsSamuel Thibault
To get mach_msg_type_number_t everywhere
2023-08-08Homogeneize [gs]et_translator and get_dire[nc]ts into mach_msg_type_number_tSamuel Thibault
This makes netfs_[gs]et_translator use mach_msg_type_number_t like the RPC and diskfs. This also makes the fshelp_fetch_root_callback1_t for fshelp_fetch_root use mach_msg_type_number_t. This also makes procfs_get_translator and the get_translator proc method use mach_msg_type_number_t. This makes diskfs_get_directs use mach_msg_type_number_t like the dir_readdir RPC Also get rid of u_int. This notably fixes _diskfs_translator_callback1_fn's bogus cast of size_t *argz_len into (u_int *).

2023-05-11Only use host_get_kernel_version and default_pager_paging_storage_new in x86_64.Flavio Cruz
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.

2023-04-25Use c_string for default_pager_filename_t to define a new ↵Flavio Cruz
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>
2023-04-15Remove default_pager_paging_file RPC from default pagerFlavio Cruz
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. Message-Id: <ZDoyNOE0XB77d5xj@mars.tail36e24.ts.net>
2023-04-08Use long_integer_t for exception_raise RPCsFlavio Cruz

2023-04-08Further modernize Hurd code by enforcing strict prototypes and no implicit ↵Flavio Cruz
function declarations. Most of the changes land in one of these buckets: * Removed unused declarations. * Used (void) to represent no parameters instead of () which means an undeterminate number of parameters. * Included missing header files whenever necessary (stdlib.h, sys/mman.h, etc) * Typedefed function pointers to be able to fully declare the parameter types. * Added declarations of library functions that are used elsewhere (example is libps/ps.h). * Made functions static whenever they are only used in that file. * Forwarded declarations of some methods that were made static.

2022-08-23file_exec: Homogeneize adding the gratuitous send rightSamuel Thibault
2022-08-23Fix spurious EINTR while exec() within fakerootSamuel Thibault
The scenario is: - process running inside fakeroot exec()s - fakeroot forwards the exec call - exec starts thrashing the previous process, and notably close its ports - the send port that pointed to fakeroot is thus closed - fakeroot thus receives a no-senders notification - its libports thus interrupts the current RPC on it, i.e. the exec(), because it thinks that the caller is no more, but that was exactly the point of the exec()... - exec tries to interrupt its own RPCs, at best the execution will fail, at worse the process is already thrashed and there's nothing better than burying it for good. The symptom is processes running inside fakeroot seeming randomly crashing with SIGKILL. Making fakeroot keep a send right avoids the no-senders notification, thus the whole interruption (which was meaningless).
2022-02-25mtab: turn part:x:device:y into /dev/ysxSamuel Thibault
This is needed when using a rumpdisk-based root disk. Otherwise fsck does not properly detect when it is mounted.
2022-01-17Fix const warningsSamuel Thibault
Now that the RPCs have const, this forces us cleaning our const-meant functions.

2022-01-01Fix build warningsSamuel Thibault
No actual behavior change.
2022-01-01random: export __trivfs_server_nameSamuel Thibault
Making glibc access trivfs_server_name would violate namespace constraints, so we need to use a out-of-standard name.
2021-12-31random: try opening time from gnumach before from /dev/timeSamuel Thibault
The system-wide random translator can access time from gnumach, while /dev/time comes from storeio, and its libc initialization (starting from glibc 2.34) uses /dev/random, which was thus bringing an initialization loop.
2021-12-30random: Add a trivfs_server_nameSamuel Thibault
glibc uses /dev/urandom for getrandom(), and from version 2.34 malloc initialization uses it. We need to be able to know whether we are running the random translator itself, in which case we can't read ourself.

2017-09-12Traverse translator hierarchies using the fsys protocol.Justus Winter
Previously, we used the fs protocol to traverse the translator hierarchies. This, however, is conceptually flawed, because translators are bound to nodes, and a node can have zero or more links in the file system. Therefore, the previous method of returning a list of paths to the client and expecting them to be able to follow these to reach the child translators was always unreliable. Fix this by using the fsys protocol to traverse the hierarchy, and returning the control ports of all children. This is more robust, and also conceptually cleaner, because the fsys protocol is about translator linkage, hence this is the point to implement traversal. Also move the get source routine over. A per-node source really does not fit the reality of most translators, while a per-translator source makes sense in many cases. * hurd/fs.defs (file_get_children): Drop routine.
