similar to: [PATCH supermin] ext2: Create symlinks properly (RHBZ#1470157).

The ext2 filesystem on disk format has two ways to store symlinks. For symlinks >= 60 bytes in length, they are stored as files (so-called "slow symlinks"). For shorter symlinks the symlink is stored in the inode ("fast symlinks"). Previously we only created slow symlinks even if they are shorter than 60 bytes. This didn't matter until recently, when a change went

Obviously for very large files this is going to be a problem, as well as not being very cache efficient. libext2fs can handle writes to parts of files just fine so copy files in blocks. Also demote the "Permission denied" error to a warning, and add some explanatory text telling people not to use sudo. --- src/ext2fs-c.c | 127 +++++++++++++++++++++++++++++++++++----------------------

Use an helper struct for holding the ext2_filsys variable, so that can be used to add more data. --- src/ext2fs-c.c | 77 +++++++++++++++++++++++++++++++--------------------------- 1 file changed, 41 insertions(+), 36 deletions(-) diff --git a/src/ext2fs-c.c b/src/ext2fs-c.c index 70755c9..8eab24c 100644 --- a/src/ext2fs-c.c +++ b/src/ext2fs-c.c @@ -52,6 +52,11 @@ /* fts.h in glibc is broken,

From: "Richard W.M. Jones" <rjones@redhat.com> This plugin allows you to create a complete ext2 filesystem in a GPT partitioned disk image. This can be attached as a disk to a Linux virtual machine. It is implemented using libext2fs (the same as supermin). Although there is some overlap with nbdkit-iso-plugin and nbdkit-floppy-plugin, the implementations and use cases of all

Hello, This patch adds rollback support for the converter, the converter can roll back a conversion if the image file haven't been modified.

Hello, There is a new feature ''uninitialized block groups'' in ext4. Block and inode bitmaps in uninitialized block groups are uninitialized. This confuses the converter. The fix is call ext2fs_new_inode for each block group at open time. It set up uninitialized block and inode bitmaps appropriately. This patch also contains some other minor fixes. Thank you, Signed-off-by: Yan

Hello, Recently, I am coding a program about read and write control. And there are some questions confusing me. 1. In info libext2fs: Function: errcode_t ext2fs_get_blocks (ext2_filsys FS, ext2_ino_t INO, blk_t *BLOCKS) Returns an array of blocks corresponding to the direct, indirect, doubly indirect, and triply indirect blocks as stored in the inode structure. So I wrote some codes like

We created symlinks in two steps, by creating the empty inode and then calling ext2fs_symlink to populate it. This created broken symlinks where the directory name contained a / character, eg: lrwxrwxrwx 1 root root 7 Nov 26 08:43 /bin -> usr/bin lrwxrwxrwx 1 root root 7 Nov 26 08:43 /lib -> usr/lib lrwxrwxrwx 1 root root 9 Nov 26 08:43 /lib64 -> usr/lib64 lrwxrwxrwx 1

Two simple build fixes for libldm. Well, the first isn't a build fix as such, but a code improvement. Rich.

When using ext2file=exportname to pick the file to server from the client's export name, we do not want to leak the underlying plugin's export list. While touching this, take advantage of string lifetimes via nbdkit_strdup_intern and similar for less cleanup bookkeeping. Note that we don't actually implement a full .list_exports; doing that with NBD_OPT_LIST is likely prohibitive

Avoids the warning: libtoolize: Remember to add 'LT_INIT' to configure.ac. This is the new name for AC_PROG_LIBTOOL, so I removed that. However to use this macro we must enable AC_USE_SYSTEM_EXTENSIONS.

Hi, to ease debugging issues with appliances (e.g. when used in libguestfs), using --include-packagelist will add a file containing the list of all the packages used.

This is not intended for v1.14. In fact, we may decide that the second patch is too gross, although the first one still seems like a useful improvement in isolation. I will also point out that all our filters are in-tree, and set the user-controlled field .version to the current release string. We could replace the second patch with a simpler one that just checks ._api_version as an int (as

Dear friends, I failed to buld samba 3.0.30 for tru64unix 4.0F. I am curently locked to this os version due to other production software. We currently run Samba 2.2.8a but we were requested to upgrade by our network group. I downloaded 3.3.30 and did $ cd source $ ./configure no warnings or errors as far as I could see, except checking for replacing readdir using getdirentries()...

Quite a complex fix in the end, see the comment in the second commit. Rich.
