* rr.c (rrip_work): Use strdup instead malloc and strcpy.
Assert that strdup and malloc (for rr->trans) succeeds.
* pager.c: Include <errno.h>.
(create_disk_pager): If malloc fails, exit with error.
* main.c (read_sblock): Fail if malloc does.
* inode.c (diskfs_cached_lookup): When allocating memory for dn or
np fails, release spinlock, rrip (and allocated memory) and return
ENOMEM.
(load_inode): Likewise (but no rrip). Also, if *npp is non-zero,
release diskfs_node_refcnt_lock before returning.
Reported by Igor Khavkine <i_khavki@alcor.concordia.ca>.

* init.c (process_rc_script): If malloc fails, return ENOMEM.
Reported by Igor Khavkine <i_khavki@alcor.concordia.ca>.
|
|
* dir.c (ftpfs_dir_create): New macro INIT_HTABLE_LEN to
specify initialize htable_len. New variable htable,
allocate memory to it with calloc before acquiring a node
reference. If this fails, return any allocated memory and
return with ENOMEM. Set new->htable_len to INIT_HTABLE_LEN
and new->htable to htable. Don't bzero htable anymore, as
we use calloc.
|
|
* pager.c: Include <errno.h>.
(create_disk_pager): Panic if malloc fails.
Reported by Igor Khavkine <i_khavki@alcor.concordia.ca>.
* inode.c (diskfs_get_translator): If malloc fails, set err to ENOMEM.
Initialize err with 0, and return it at the end of the function.
Reported by Igor Khavkine <i_khavki@alcor.concordia.ca>.

* boot.c (main): If malloc or realloc fails, print diagnostic
message and exit.
(queue_read): Change return type from void to kern_return_t.
If malloc fails, return D_NO_MEMORY, otherwise D_SUCCESS (to simplify
code flow, malloc before acquiring the queuelock).
(ds_device_read): New variable err (local to the block in which it is used).
If queue_read fails, pass through error.
(ds_device_read_inband): Likewise.
(S_io_read): Likewise.
Reported by Igor Khavkine <i_khavki@alcor.concordia.ca>.

* dir-lookup.c (netfs_S_dir_lookup): Do not bother zeroing np, it
happens later anyway. Replace bcopy with memcpy.
* file-get-translator.c (netfs_S_file_get_translator): Replace
bcopy with memcpy.
* io-seek.c (netfs_S_io_seek): Only get the lock if we need it.
* io-stat.c (netfs_S_io_stat): Replace bcopy with memcpy.
* io-write.c (netfs_S_io_write): Wait until the lock is needed.

is now very explicit.
* nput.c (netfs_nput): Added comment.
* nrele.c (netfs_nrele): Likewise.
* set-get-trans.c: Likewise.
|
|
|
|
* node.c (recompute_blocks): New function, broken out of ...
(diskfs_cached_lookup): here. Now use call that.
(diskfs_set_translator): Likewise.
(create_symlink_hook): Likewise. Do nothing for zero-length target.
|
|
|
|
|
|
* file-statfs.c (diskfs_S_file_statfs): Zero out the struct statfs
before calling diskfs_set_statfs. Set f_namelen to diskfs_name_max
after the call.
* diskfs.h: Update comment.
|
|
|
|
* zero.c (zero_open): Check for END being null after strtoul call.
If character following number (*END) is b, multiply size by 512;
k or K, by 1024; m or M by 1024*1024; g or G by 1024*1024*1024.

|
|
* store.h (struct store_class): Fix typo in comment.
|
|
|
|
* copy.c (copy_read): When reading whole aligned pages, use vm_read.
Use MAP_FAILED in place of (void *) -1. Use memcpy in place of bcopy.
(copy_write): When reading whole aligned pages, use vm_write.
Use memcpy in place of bcopy.
|
|
|
|
* inode.c (write_node): Remove assert that dn_set_mtime et al are
clear. It is ok if they are set in parallel, because the latter
setting will be carried out eventually.
|
|
* main.c (pfinet_demuxer): New variable PI.
Store port info in PI, and dereference it if found.
|
|
|
|
* truncate.c (diskfs_truncate): Use & instead of %.
|
|
* inode.c (write_all_disknodes): Call diskfs_set_node_times after
pokel_sync, since it might delay a little.
(write_node): Remove assert that dn_set_mtime et al are clear.
It is ok if they are set in parallel, because the latter setting
will be carried out eventually.
|
|
* node-times.c (diskfs_set_node_times): Make individual flag checks
race-proof so we don't lose any flag settings.
|
|
* ops.c (op_readlink): Before returning, check if the buffer
pointed to by transp is ours. If not, munmap it.
(op_read): Likewise for bp.
(op_readdir): Don't alloca a buffer here. Instead initialize
BUF and BUFSIZE to 0 and let the server (eh, MiG) do it.
munmap BUF before returning.
|
|
* cache.c (scan_creds): Move I inside for-statement.
Replace inner for-loop with a while-loop. New variable
NEXT_I set to I->NEXT, because we might free I.
Set I to NEXT_I at end of while block.
Move update of leastidlastuse inside if block, because
otherwise we will constantly prevent ourself from scanning.
(scan_fhs): Very much the same.
(scan_replies): Likewise. Also free CR.
(check_cached_reply): Make HASH value absolute (as XID can be
negative, and thus the modulus).
Initialize REFERENCES to 1.

The last two changes introduced two new inode overlaps
(file_start was not shifted by store block size, and directories'
shifted file_start offset can be the same as the struct dirrect
offset of their first directory entry).
* inode.c (use_file_start_as_id): New function to determine
if to use file_start or struct dirrect * as node id.
The directory recognition code comes from read_disknode.
(cache_inode): Use use_file_start_as_id instead doing the work
ourselve. Shift file_start by store->log2_block_size.
(load_inode): Likewise.
* lookup.c (diskfs_get_directs): Likewise.
Declare use_file_start_id.
|
|
* ops.c (netfs_attempt_mkdir): Add casts -1 -> (struct iouser *) -1
to silence gcc warning.
(netfs_attempt_create_file): Likewise.

Fix hard link handling for non-zero length files.
* inode.c: Fix comment about inode numbers.
(node_cache): New member ID to store unique identifier.
(inode_cache_find): Change RECORD arg into ID and compare it
with id member of node_cache.
(cache_inode): Swap order of args and add new arg RR (change dr
into record along the way). Use RR to find out cache ID.
Use id member of node_cache to look for ID. Cache ID.
(load_inode): Call inode_cache_find with correct ID, depending
on RR and file size. Frob arguments to cache_inode to comply with
the new definition.
(read_disknode): Set st_ino according depending on RR and file size.
* lookup.c: Doc spelling fix.
(diskfs_get_directs): Include code again that was removed by last change,
but use it only if not symlink or zero length file.

Closes Debian Bug #68417:
* rr.c (rrip_work): In helper function add_comp set targused to
zero after malloc, and loop over realloc in case doubling is not
enough. After finalizing the link, set VALID_SL valid flag.
* inode.c (read_disknode): For links use rl->target instead
rl->name.
Closes Debian Bug #69281: Don't use file_start as inode numbers,
but the offset of the directory record in disk_image. This is what
Linux 2.4 does.
* isofs.h (struct disknode): New member struct dirrect *dr.
* inode.c: Fix comment about inode numbers.
(struct node_cache): Fix comment about file_start (it's not unique).
In fact, file_start is invalid for symlinks, and only stored here
for convenience. Maybe caching file_start can be avoided by
rearranging the code.
(inode_cache_find): Change first argument from off_t file_start
to struct dirrect *dr and fix the doc.
Compare cached value of DR with this argument, instead FILE_START.
(diskfs_cached_lookup): Set DR member of DN.
(load_inode): Call inode_cache_find with RECORD instead FILE_START.
Set DR member of DN.
(read_disknode): Set inode number to DR - DISK_IMAGE instead
FILE_START.
* lookup.c (diskfs_get_directs): Remove variable file_start.
Don't calculate file_start. Set D_FILENO to EP - DISK_IMAGE
instead FILE_START.

Update prototype of configure_device.
Set trivfs_support_read and trivfs_support_write to 1, as we support
those in some cases now. For the same reason, set trivfs_allow_open
to O_READ | O_WRITE.
(pfinet_demuxer): If the port is not in the socketport_class,
don't try io_server (so requests for trivfs are not catched too early).

* Makefile (SRCS): Add dummy.c
* dummy.c: New file.
* ethernet.c: Moved ETHER_PORT, READPT, READPTNAME to ...
(struct ether_device): ... here. New struct. ETHER_DEV is now a
pointer to a struct ether_device.
(ethernet_demuxer): New variables edev, dev. Iterate over linked
list ETHER_DEV to find correct readptname. Use dev instead
ETHER_DEV for socket buffer manipulation.
