2014-06-15Prepare the procfs translator to be merged into the Hurd sourcesHEADmasterJustus Winter
Move the procfs translator to its own subdirectory 'procfs'. This is the last commit to this repository. Development of the procfs translator will continue in the main Hurd repository. * procfs/Makefile: Replace the standalone Makefile with the one from the Debian packaging repository.
2013-08-28procfs: provide a more meaningful response to fsys_get_optionsJustus Winter
Implement our own netfs_append_args function that provides the appropriate command line flags if the current values differ from the default values. * procfs/main.c (netfs_append_args): New function.
2013-08-28procfs: define macros for the default argument valuesJustus Winter
Define a macro for the default value of each command line parameter. This allows one to generate a minimal response to fsys_get_options requests. * procfs/main.c: New macro definitions for default values.
2013-08-28procfs: handle the --update parameterJustus Winter
Split the argument handling into a common part and one for fsys_update_options. Handle the --update parameter; for procfs this is a no-op. * procfs/main.c (common_options): New variable. (runtime_argp_parser): Handle --update. (startup_argp): New variable. (netfs_runtime_argp_): New variable.
2013-08-27Fix argument parsingJustus Winter
The switch statement was missing the default case returning ARGP_ERR_UNKNOWN. This patch adds that. * main.c (argp_parser): Add default case.
2013-07-20procfs: Ignore arguments for compatibility with Linux' procfs.Justus Winter
Ignore the --nodev, --noexec and --nosuid arguments. * procfs/main.c (argp_parser): Ignore some arguments for compatibility.
2013-06-29procfs: enable fsys_set_optionsJustus Winter
Make procfs translators handle fsys_set_options requests by pointing netfs_runtime_argp to our argp struct. * procfs/main.c (netfs_runtime_argp): New variable.
2013-06-29procfs: keep old config values if the parsing failsJustus Winter
Previously if strtol failed the previous configuration value would get overwritten. Prevent this by storing the result in a temporary variable and update the configuration if the argument was parsed correctly and passed the sanity checks. * procfs/main.c (argp_parser): Keep old configuration in case a malformed value is encountered.
2013-06-29procfs: fix the error handling in argp_parserSamuel Thibault
Do not exit using error (1, ..) but gracefully handle the error using argp_error. Also fix a typo ("the a user") while touching these lines. * procfs/main.c (argp_parser): Proper error handling. (argp_parser): Fix typo.
2010-09-14Use the user-provided kernel PID for uptimeJeremie Koenig

2010-08-30Improve the interface for dircat_make_nodeJeremie Koenig
* dircat.c, dircat.h (dircat_make_node): Use an explicit array size for DIRS, fail with ENOMEM is any of them is NULL, and release the reference on the non-NULL nodes on any error. * main.c (root_make_node): Use the new interface.
2010-08-30Fix the handling of processes without an ownerJeremie Koenig

2010-08-30Use a global ps_contextJeremie Koenig
* proclist.c, proclist.h (proclist_create_node): Use a ps_context passed by the caller; errors are no longer possible, rename to proclist_make_node and change the signature accordingly. * rootdir.c, rootdir.h (rootdir_create_node): Likewise. * main.c (main): Create the ps_context here and pass it to root_make_node. (root_make_node): Pass it to proclist_make_node and rootdir_make_node.
2010-08-30netfs_server_loop never returnsJeremie Koenig
* main.c: Don't call netfs_server_loop repeatedly; it should never return.
2010-08-30Handle errors in mainJeremie Koenig
* main.c (main): Handle errors from argp_parse and root_make_node.
2010-08-30Add a --compatible optionJeremie Koenig
