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,

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.

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 +++++++++++++++++++++++++++++++++++----------------------

Check early that there are enough free blocks to store each file, erroring out with ENOSPC if not; this avoids slightly more obscure errors later on. --- src/ext2fs-c.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) diff --git a/src/ext2fs-c.c b/src/ext2fs-c.c index f01ca9d..e45980a 100644 --- a/src/ext2fs-c.c +++ b/src/ext2fs-c.c @@ -52,6 +52,9 @@ /* 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

Hi, the two patches improve the way memory is handled in supermin, by cleanly exiting on memory allocation failures, and free'ing memory when not needed (to keep working and not run out of memory).

This patch introduce extent buffer cache for every i-node. By this way, we can save the search time and reduce the lock contention of the root because we needn''t search the item from the root of b+ tree. Implementation: - add two pointers of extent buffer into btrfs_inode struct, one for nodes/leaves of fs/file tree, the other for nodes/leaves of the log tree. - add a variant to tell

Hi. I am currently debugging an issue with libguestfs in Centos 7.2 (Kernel 3.10.0-327.36.3.el7.x86_64). libguestfs is being called by SaltStack to access a qcow2 image, but it is failing. I have narrowed the issue down to the command below: guestmount -i -a /opt/vm-spinning/salt-mnt/salt-images/pb123/system.qcow2 --rw /tmp/guest/opt.vm-spinning.salt-mnt.salt-images.pb123.system.qcow2 I have

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.

Turns out Japanese trains are good for coding! In supermin we have a bunch of code to create the libguestfs appliance. It creates it directly using libext2fs (part of e2fsprogs). We can use the same technique to create ext2 virtual disks in nbdkit, which is what this new plugin does. Why a new plugin instead of modifying the floppy plugin? See the 4/4 commit message for an explanation. The

Another interesting thing you can do with this plugin: https://rwmj.wordpress.com/2019/02/19/nbdkit-linuxdisk-plugin/ v2: - Fix inconsistent tab/space. - All 3 plugins now contain a block of text pointing to the other 2 plugins. - TMDIR -> TMPDIR - Unlink the temporary file and other cleanups along error paths. - fclose -> pclose, and check the return value for errors. -

There were a whole bunch and I was doing it for other things. I haven''t tested these error paths but at the very least this is better than panicing. I''ve only left 2 BUG_ON()''s since they are logic errors and I want to replace them with a ASSERT framework that we can compile out for production users.
