libpager: provide 'pager_create_alloc'2016-08-07T21:28:45ZJustus Winterjustus@gnupg.org2016-05-22T17:35:10Zurn:sha1:0e3a795af98b6441d0a9928036e140978511e272
Add a variant to 'pager_create' that allocates memory for the user
hook next to the pager data increasing locality.

free 'upi'.
(user_pager_create): Use the new function.
* doc/hurd.texi: Document new function.
* ext2fs/pager.c (pager_clear_user_data): Don't free 'upi'.
(diskfs_get_filemap): Use the new function.

* libpager/pager-create.c (_pager_create): New generic allocation
function.
(pager_create): Use the new generic function.
(pager_create_alloc): New function.

ext2fs: fix pager use-after-free2016-05-22T12:05:15ZJustus Winterjustus@gnupg.org2016-05-21T22:52:29Zurn:sha1:60d14f5b3c4ea27af6f4220a15947c328bc888ee
Previously, pagers had no reference for being part of a node, only for
having a send right made for them. Hence we sometimes saw
use-after-free errors if the kernel did give up that send right,
typically while deleting files. Keep a weak reference as long as the
pager is referenced by a node.
* ext2fs/pager.c (pager_clear_user_data): Assert that 'pager' has been
NULLed.
(pager_dropweak): Drop the weak reference and NULL 'pager'.
(diskfs_get_filemap): Simplify. Acquire a weak reference.
Fix supporting >4GiB files in ext2fs2016-04-26T20:41:32ZSamuel Thibaultsamuel.thibault@ens-lyon.org2016-04-26T20:37:09Zurn:sha1:f4d6b646a1aa6f8e489dd3eeae1a188de0b2a070
* ext2fs/inode.c (diskfs_user_read_node): When sizeof(off_t) >= 8, add
di->i_size_high as high-64bit part to st->st_size. Drop setting
unused info->i_high_size.
(write_node): When sizeof(off_t) >= 8, write high-64bit part of st->st_size
to di->i_size_high.
* ext2fs/ext2_fs_i.h (ext2_inode_info): Remove i_high_size field.
* pfinet/linux-src/include/linux/ext2_fs_i.h (ext2_inode_info): Likewise.
ext2fs: Fix off-by-one2016-03-17T23:12:23ZSamuel Thibaultsamuel.thibault@ens-lyon.org2016-03-17T23:12:23Zurn:sha1:c595ceac1ad8c40aec85318e07424e5b6f338dad
* ext2fs/pager.c (disk_cache_init): Do not add
disk_cache_info[disk_cache_blocks] to disk_cache_info_free.
ext2fs: Fix adding blocks to free blocks cache2016-03-14T23:27:20ZSamuel Thibaultsamuel.thibault@ens-lyon.org2016-03-14T23:27:20Zurn:sha1:b50c419c9b8f59b459d488d7bf11654d56f35511
* ext2fs/pager.c (disk_cache_info_free_push): Add prototype.
(disk_pager_notify_evict): When dropping DC_INCORE flag, if the
block becomes free (no reference and no DC_DONT_REUSE flags), call
disk_cache_info_free_push.
(disk_cache_block_deref): Only call disk_cache_info_free_push if the flags
of the block do not contain DC_DONT_REUSE flags.
Drop OTHERLIBS and use LDLIBS exclusively2015-12-31T20:47:32ZFlavio Cruzflaviocruz@gmail.com2015-12-31T16:49:25Zurn:sha1:a70c7531ed3a6378dd527da005a1fe63fbb4871a
When cross-compiling, OTHERLIBS magically turns -lpthread into the path
to the host libpthread.so file, resulting in build issues. LDLIBS does
not suffer from this problem and it seems that is already being used in
other Makefiles. This patch removes OTHERLIBS entirely from the build
system.
