similar to: [PATCH] guestmount: use O_ACCMODE instead of hard coding

This version doesn't crash or cause hung processes or stuck mountpoints, so that's an improvement. Rich.

This patch is just for review. It enables FUSE support in the API via two new calls, 'guestfs_mount_local' and 'guestfs_umount_local'. FUSE turns out to be very easy to deadlock (necessitating that the machine be rebooted). Running the test from the third patch is usually an effective way to demonstrate this. However I have not yet managed to produce a simple reproducer that

This changes the proposed API slightly. Previously 'mount-local' generating a 'mounted' event when the filesystem was ready, and from the 'mounted' event you had to effectively do a fork. Now, 'mount-local' just initializes the mountpoint and you have to call 'mount-local-run' to enter the FUSE main loop. Between these calls you can do a fork or whatever

This patch adds a readonly mode to scp and sftp_server. This allows clients to only read files from the server, but not to write them. Patch is based on OpenSSH 3.4p1 *** scp.c@@\main\1 Tue Oct 1 17:25:16 2002 --- scp.c Wed Oct 2 06:05:14 2002 *************** *** 122,127 **** --- 122,130 ---- /* This is set to zero if the progressmeter is not desired. */ int showprogress = 1; + /* deny

Hello. These patches add a new mode of operation for the sftp server. It is located between the ordinary, unrestricted mode and read-only mode. It allows you to add files to the server, but only if these files do not exist on the server before. Changes to existing files - are prohibited. Please review them, maybe these patches will be useful not only to me. Thank you. -------------- next part

This program allows you to turn a network block device source into a FUSE filesystem containing a virtual file: $ nbdkit memory 128M $ mkdir mp $ nbdfuse mp/ramdisk nbd://localhost & $ ls -l mp total 0 -rw-rw-rw-. 1 rjones rjones 134217728 Oct 12 15:09 ramdisk $ dd if=/dev/urandom bs=1M count=128 of=mp/ramdisk conv=notrunc,nocreat 128+0 records in 128+0 records out

My two cents: - I think inline assembly should work even if the compiler cannot parse the contents. This would rule out msvc inline assembly (or alternatively put all the parsing and interpretation burden on the frontend), but would work with gcc asm goto which specifies possible targets separately. - Supporting control flow in inline assembly by allowing jumps out of an assembly block seems

It seems that FUSE can invoke flush to make sure the pending changes (e.g. to the attributes) of a file are set. Since a missing flush implementation is handled as if it were returning ENOSYS, this can cause issues later. To overcome this, just provide a stub implementation which does nothing, since we have nothing to do and don't want to have FUSE error out. Furthermore, uncomment the

Updating gnulib has caused -Wformat-signedness to be enabled. This has revealed many problems in C format strings. The fixes here fall into the following main categories: - Using %d with an unsigned parameter. - %x and %o expect an unsigned argument. - uid_t and gid_t are unsigned on Linux. The safe way to print these is to cast them to uintmax_t and then print then using the %ju

Hello everybody, I been trying to debug a problem for a month now and can use some insights and advice. This is the setup, I got two linux ha storage node providing iscsi disk, the disks is mounted on two linux kvm host and one backup server. The iscsi disk has lvm on it, the logical volume groups are visible on all servers. On the backup server I have the following running: # guestmount

Currently guestfish has mount-vfs, and the libguestfs API has guestfs_mount_vfs(), but guestmount doesn't allow the user to specify a filesystem. This patch extends the --mount argument, so you can force an ext2 partition to mount as ext4: guestmount -a mydisk.img -m /dev/vda:/:defaults:ext4 mountpoint You could also use it to choose between ntfs and ntfs-3g, or between hfsplus and the
