2014-03-26Fix setting LGE flagSamuel Thibault
* console-client/vga-support.c (vga_set_font_width): Fix setting the `VGA_ATTR_MODE_LGE' flag.
2014-03-26Merge branch 'master' of git.savannah.gnu.org:/srv/git/hurd/hurdSamuel Thibault
2014-03-26Align VGA buffersSamuel Thibault
Some "hardware" (such as kvm on linux 3.2) would hang when transferring between video memory and unaligned main memory. This also allows better optimized transfers anyway. Thanks Petter Reinholdtsen for the report and patient tests. * console-client/vga-support.c (vga_state): Force maximum alignment of `videomem' and `fontmem' fields.
2014-03-25mach-defpager: replace the magic typecast with a hash tableJustus Winter
Previously, the mach-defpager used a "magic typecast" for object lookups. It renamed the port to the address of the associated object, and upon receiving a message it would cast the port name back to a pointer. While this might seem like an optimization, it actually makes the port handling in the kernel less efficient. Ports with small continuous names are stored in an array, while other ports get spilled in a splay tree. Replace the linked list of default_port_t objects with a hash table. Do not rename the ports, rather use the hash table to lookup objects associated with ports. * mach-defpager/default_pager.c (struct pager_port): Replace queue with hash table, remove count, move type declaration to priv.h. (pager_port_list_init): Adjust accordingly. (pager_port_list_insert): Likewise. (pager_port_list_delete): Likewise. (destroy_paging_partition): Replace queue_iterate with HURD_IHASH_ITERATE. (S_default_pager_objects): Likewise. (S_default_pager_object_pages): Likewise. (seqnos_memory_object_create): Do not rename the port but store it in the hash table. (S_default_pager_object_create): Likewise. * mach-defpager/priv.h (struct dstruct): Add fast-removal pointer. (pnameof): Remove obsolete macro definition. (dnameof): Likewise. * mach-defpager/mig-decls.h (begin_using_default_pager): Replace the magic typecast with a hash table lookup. * mach-defpager/Makefile (HURDLIBS): Add ihash.

2014-03-21libpager: fix comment of pager_change_attributesJustus Winter
* libpager/pager-attr.c: Fix comment. * libpager/pager.h: Likewise.
2014-03-20Make bz2 and gz support optionalGabriele Giacone

2014-03-16Fix crash on opening /dev/kbd or mouse without any console being activeSamuel Thibault
* console-client/console.c (console_switch_away): Check for `active_vcons` being NULL before saving the currently active console.
2014-03-12mach-defpager: silently ignore requests to page to active partitionJustus Winter
Currently, if mach-defpager is asked to page to an already active partition, it ignores this request and returns success. It does, however, print a message about this to stdout. This message might indicate to the user that there is some kind of a problem with the configuration of the machine, even though the code in new_partition clearly does not consider it an error to do such an request. * mach-defpager/default_pager.c (new_partition): Do not print a message if requested to page to an already active partition.
2014-03-12mach-defpager: fix type of size argumentsJustus Winter
* mach-defpager/default_pager.c (new_partition): Fix type of bsize. * mach-defpager/file_io.h (page_read_file_direct): Fix type of size argument. (page_write_file_direct): Likewise. * mach-defpager/setup.c (page_read_file_direct): Likewise. (page_write_file_direct): Likewise.
2014-03-12mach-defpager: fix warnings about uninitialized variablesJustus Winter
* mach-defpager/default_pager.c (S_default_pager_objects): Initialize address, size-pairs to 0. (S_default_pager_object_pages): Likewise. * mach-defpager/kalloc.c (kget_space): Likewise.
2014-03-12mach-defpager: fix warning about uninitialized variableJustus Winter
Previously, failure to look up the given partition was detected after the loop by checking whether the loop ran over all existing partitions. Initialize part to NULL and check for that instead. This retains the behavior, but expresses it in a way the compiler understands better. * mach-defpager/default_pager.c (destroy_paging_partition): Initialize part to NULL and check for it still being NULL after the loop.
2014-03-12mach-defpager: fix error handling in S_default_pager_object_set_sizeJustus Winter
Fix a compiler warning about kr being potentially being uninitialized. * mach-defpager/default_pager.c (S_default_pager_object_set_size): Initialize kr.

2014-03-12mach-defpager: remove comments around form feedsJustus Winter
Form feed characters (\f) are whitespace and are treated as such by c compilers. There is no need to enclose them in comments. * mach-defpager/default_pager.c: Remove comments around form feeds.
2014-03-01auth: improve the mig mutator functionsJustus Winter
Previously, the mig mutator function auth_port_to_handle was defined in auth.c (fakeauth.c), preventing it from being inlined into the mig-generated server functions. Put it in mig-decls.h instead. Rename authmutations.h to mig-mutate.h, auth_mig.h to mig-decls.h. This is the naming convention used for pflocal. * auth/auth.h: New file. * auth/auth_mig.h: Rename to mig-decls.h, add copyright notice, define mutator functions. * auth/authmutations.h: Rename to mig-mutate.h, restore copyright notice, adjust accordingly. * auth/auth.c: Include auth.h, remove auth_port_to_handle. * utils/fakeauth.c: Likewise. * auth/Makefile: Adjust accordingly. * utils/Makefile: Likewise.

* hurd/iioctl.defs: Add IIOCTL_IMPORTS.
2014-02-25libtrivfs: improve the mig mutator functionsJustus Winter
Previously, the mig mutator functions were in migsupport.c, preventing them from being inlined into the mig-generated server functions. Put them in mig-decls.h instead. Rename mutations.h to mig-mutate.h. This is the naming convention used for pflocal. * libtrivfs/fsmutations.h: Rename to mig-mutate.h, adopt imports. * libtrivfs/Makefile: Adopt accordingly. * libtrivfs/migsupport.c: Rename to mig-decls.h. * libtrivfs/trivfs.h: Move dynamic classes/buckets declarations to mig-decls.h, remove superfluous imports. * exec/execmutations.h: Fix import. * pfinet/mig-mutate.h: Likewise. * trans/Makefile: Likewise.

2014-02-25New RPCs, fix buildJustus Winter
2014-02-25trans/mtab: do not map unknown source strings to "none"Justus Winter
Previously, map_device_to_path mapped unknown device strings to "none". Return a copy of the original source string instead so that e.g. nfs mount point points are properly handled. * trans/mtab.c (map_device_to_path): Do not map unknown source strings to "none".
2014-02-25tmpfs: set diskfs_disk_name to "none"Justus Winter
By default diskfs_disk_name is returned as the source of libdiskfs-based translators. Hurds fstab allows multiple entries with the mnt_fsname being "none". * tmpfs/tmpfs.c (diskfs_disk_name): Set to "none".
2014-02-25trans/mtab: ignore translators that do not implement file_get_sourceJustus Winter
Previously, the mtab translator would guess the source of a filesystem translator from its last argument. This made all kinds of non-filesystem translators appear in /proc/mounts, causing severe problems due to umount --all removing vital passive translator records. Fix this by ignoring all translators that do not explicitly implement file_get_source. * trans/mtab.c (mtab_populate): Ignore translators that do not implement file_get_source.
2014-02-25nfs: implement netfs_get_sourceJustus Winter
Implement netfs_get_source so that nfs translators show up in /proc/mounts. * nfs/main.c (netfs_get_source): New function.

2014-02-25mach-defpager: improve the default_pager_demux_object functionJustus Winter
Handle multiple request types as recommended by the Mach Server Writer's Guide section 4, subsection "Handling Multiple Request Types". This avoids initializing the reply message in every X_server function. * mach-defpager/default_pager.c (default_pager_demux_object): Improve the demuxer function.
2014-02-25mach-defpager: add function mig_reply_setupJustus Winter
Currently, mig_reply_setup is not provided by libmachuser or the glibc. Provide it locally. * mach-defpager/default_pager.c (mig_reply_setup): New function.
2014-02-25mach-defpager: fix definition of seqnos_memory_object_data_unlockJustus Winter
* mach-defpager/default_pager.c (seqnos_memory_object_data_unlock): Fix function arguments.
2014-02-25libpager: improve the pager_demuxer functionJustus Winter
Handle multiple request types as recommended by the Mach Server Writer's Guide section 4, subsection "Handling Multiple Request Types". This avoids initializing the reply message in every X_server function. The reply message has already been properly initialized in libports, so there is no need to call mig_reply_setup. * libpager/demuxer.c (pager_demuxer): Improve the demuxer function.
2014-02-25utils/umount: do not remove passive translator recordsJustus Winter
Passive translator records are a Hurd concept. Therefore, the umount compatibility program should not remove them. * utils/umount.c (passive_flags): Unset FS_TRANS_SET. (doc): Adjust accordingly.
2014-02-25Fix fakeroot and remap parsing corner casesSamuel Thibault
Fix case when $PWD contains spaces. Pass directly arguments to command, to directly avoid escaping issues. Based on suggestion by Ivan Shmakov <oneingray@gmail.com> * utils/fakeroot.sh (TARGET): Do not define. (sh): Rather pass PWD and commandline as parameters. * utils/remap.sh: Likewise.
2014-02-23exec: provide a meaningful name for new tasksJustus Winter
The name will be used in error messages printed by the kernel. This makes attributing the errors to processes possible. * exec/exec.c (do_exec): Set the name of the new task.
2014-02-22pfinet: set a non-zero ports management timeoutRichard Braun
* pfinet/main.c (main): Call ports_manage_port_operations_multithread with non-zero timeouts.
2014-02-22libports: work around bugs in server terminationRichard Braun
Most servers use ports_manage_port_operations_multithread to process requests and terminate when it returns. Since many of them don't detach before shutting down, a client may receive an error if its request arrived while the server is shutting down. Prevent those spurious errors by forcing ports_manage_port_operations_multithread not to return. * libports/manage-multithread.c (ports_manage_port_operations_multithread): Force global_timeout to 0.
