* rdwr-internal.c (_diskfs_rdwr_internal): Short-circuit return for
zero-length transfer to avoid side effects, as POSIX requires.
|
|
* pager-memcpy.c (pager_memcpy): Short-circuit return for zero size.
|
|
|
|
* nonsugid.c (get_nonsugid_ids): Remove saved set IDs from available
sets before merging effective sets.
|
|
|
|
* pager.c (file_pager_write_page): Lock NODE->dn->alloc_lock
before accessing NODE->allocsize. Fixes Debian bug #40302.
|
|
|
|
* cprocs.c: Include <assert.h>
|
|
|
|
* cprocs.c (cproc_alloc): Initialize P->wired and P->msg here (code
from cthread_wire).
(cthread_wire): Reduce to just an assert, cthreads always wired.
(chtread_unwire): Abort if called.
|
|
|
|
* primes.c: File removed (long obsolete).
* proc.h: Don't declare nextprime.
|
|
* file_io.h: Include "../ext2fs/ext2_fs.h" instead of "ext2_fs.h".
* ext2_file_io.c (search_directory): Use `struct ext2_dir_entry_2' in
place of `struct ext2_dir_entry', so as to grok newer dir formats.
* ext2_fs.h: File removed.
* Makefile (LCLHDRS): Remove it from the list.
* ffs_compat.c (EXT2_INODES_PER_BLOCK): New macro, no longer in
ext2_fs.h.

Rewrite of a fix provided by Bill White <bill.white@griggsinst.com>:
* fhandle.h (union diskfs_fhandle): Replaces struct diskfs_fhandle.
Use a union element of char[28] to ensure size requirement.
* fsys-getfile.c (diskfs_S_fsys_getfile): Update uses for new type.
* file-getfh.c (diskfs_S_file_getfh): Likewise.
|
|
|
|
* null.c: Support --full/-f option to be /dev/full (ENOSPC writes).
(write_error_code): New variable.
(options, argp): New static const variables.
(parse_opt): New function.
(main): Move local ARGP out to static.
(trivfs_S_io_write): Return write_error_code instead of zero.
|
|
* MAKEDEV.sh (mkdev: full): New device, using /hurd/null --full.
(mkdev: std): Add full to the standard list.
|
|
|
|
* io-read.c (diskfs_S_io_read): Add braces to silence gcc
warning.
|
|
|
|
* storeio.c (trivfs_modify_stat): Clear writable bits if open store is
readonly, not just if we got the --readonly switch.
|
|
|
|
* MAKEDEV.sh (mkdev: time): Use --no-cache flag.
(mkdev: mem): New storeio device.
(mkdev: std): Add mem to standard list.
|
|
* lookup.c (dirscanblock): Add const to type of NAME parameter.
(isonamematch): Likewise.
* rr.c (rrip_match_lookup): Likewise.
(rrip_work): Likewise. Change char -> size_t for MATCH_NAMELEN.
* rr.h: Update decls.
|
|
* dev.c (dev_read, dev_write): In DEV->inhibit_cache case,
handle zero (i.e. unknown) block_size by treating it as 1.
Use shift and bitwise-and rather than multiply and modulus
for block size arithmetic, since it's a known power of two.
|
|
* store.h (struct store_class): Add const to type of `name' member.
|
|
* storeinfo.c (print_store: pstr): Add const to parameter type.
|
|
|
|
* dlabel.c (fd_get_device): Check STORE->class->id, not STORE->class.
|
|
|
|
* mount.c: New file.
* mount.sh: File removed.
* Makefile (special-targets): Remove mount.
(SRCS): mount.sh -> mount.c
(mount): Add deps on ../sutils/fstab.o, ../sutils/clookup.o,
libfshelp and libports.
(../sutils/fstab.o ../sutils/clookup.o): Rule to build in ../sutils.
|
|
* Makefile (progs, scripts): New variables.
(targets, special-targets, SRCS, OBJS): Define in terms of those.
(libshouldbeinlibc dep rule): Replaced with static pattern rule
with $(progs) as target list, giving %.o dep as well.

* fstab.c (fstypes_get): Check strdup return for ENOMEM failure.
(fstypes_find_program): New function, #if 0'd out for now.
(fstab_argp, fstab_argp_create, options, parse_opt): New variables
and functions.
* fstab.h: Misc comment fixes.
(struct fstab_argp_params): New type.
(fstab_argp, fstab_argp_create): Declare them.
* fsck.c (options): Remove --fstab/-F, --search-fmts/-S,
--exclude-root/-R, --exclude/-X, --fstype/-t, --all/-A;
all of these are now factored out into fstab_argp.
(main): Remove parsing code for options now in fstab_argp.
Instead, use fstab_argp as an argp_child and use fstab_argp_create
to process the option-parsing results into a struct fstab * to process.
* fstab.c (fstab_read): Undo change of 1999-09-17.
It should not be necessary at all, given 1999-05-23 change, and:
(fstab_find_mount): Do not consider name "ignore" to match any mount.

* swapon.c (swaponoff): Check for a null default pager port.
|
|
|
|
* default_pager.c (default_pager): Instead of suspending this thread,
just become the default_pager_default_thread thread ourselves.
|
|
* mach-defpager: New directory. See its ChangeLog.
Makefile (prog-subdirs): Add mach-defpager.
|
|
* Makefile, main.c: New files for new this directory `mach-defpager'.
This is a standalone Hurd program version of the Mach default pager,
with the bulk of the source code coming from ../serverboot.
This program /hurd/mach-defpager is started like a normal daemon,
i.e. from rc or whatever, rather than being the first task.
* ChangeLog: New file, mentioning itself in this sentence.
|

|
|
* dev.h (struct dev): New member `enforced'.
* storeio.c (enforce_store): New variable.
(options, parse_opt, trivfs_append_args): Grok new option
--enforced/-e to set enforce_store.
(check_open_hook): Set DEVICE->enforced from enforce_store.
* io.c (trivfs_S_file_get_storage_info): If DEV->enforced is set
and the store flags lack STORE_ENFORCED, then return STORAGE_OTHER.
|
|
* storeio.c (check_open_hook): Don't check for D_NO_SUCH_DEVICE here.
Translation to ENXIO now done in libstore.
* dev.h (struct dev): New member `enforced'.
* storeio.c (enforce_store): New variable.
(options, parse_opt, trivfs_append_args): Grok new option
--enforced/-e to set enforce_store.
(check_open_hook): Set DEVICE->enforced from enforce_store.
* io.c (trivfs_S_file_get_storage_info): If DEV->enforced is set
and the store flags lack STORE_ENFORCED, then return STORAGE_OTHER.
|
|
* io.c (trivfs_S_file_get_storage_info): Fail with EOPNOTSUPP when
there is no store open.
* dev.h (struct dev): New member `enforced'.
* storeio.c (enforce_store): New variable.
(options, parse_opt, trivfs_append_args): Grok new option
--enforced/-e to set enforce_store.
(check_open_hook): Set DEVICE->enforced from enforce_store.
* io.c (trivfs_S_file_get_storage_info): If DEV->enforced is set
and the store flags lack STORE_ENFORCED, then return STORAGE_OTHER.
