This is done by redirecting modifying operations -+to a writeable location called "storage directory", and leaving the -+original data in the "base directory" untouched. When reading, the -+file system merges the modifed and original data so that only the -+newest versions will appear. This occurs transparently to the user, -+who can access the data like on any other read-write file system. -+ -+Base and storage directories may be located on the same or on -+different partitions and may be of different file system types. While -+the storage directory obviously needs to be writable, the base may or -+may not be writable, what doesn't matter as it will no be modified -+anyway. -+ -+ -+WHAT IS GOOD FOR? -+----------------- -+ -+The primary purpose of the mini_fo file system is to allow easy -+software updates to embedded systems, that often store their root -+file system in a read-only flash file system, but there are many -+more as for example sandboxing, or for allowing live-cds to -+permanently store information. -+ -+ -+BUILDING -+-------- -+This should be simple. Adjust the Makefile to point to the correct -+kernel headers you want to build the module for. Then: -+ -+ # make -+ -+should build "mini_fo.o" for a 2.4 kernel or "mini_fo.ko" for a 2.6 -+kernel. -+ -+If you are building the module for you current kernel, you can install -+the module (as root): -+ -+ # make install -+ -+or uninstall with -+ -+ # make uninstall -+ -+ -+USING THE FILE SYSTEM -+-------------------- -+ -+the general mount syntax is: -+ -+ mount -t mini_fo -o base=<base directory>,sto=<storage directory>\ -+ <base directory> <mount point> -+ -+Example: -+ -+You have mounted a cdrom to /mnt/cdrom and want to modifiy some files -+on it: -+ -+load the module (as root) -+ -+ # insmod mini_fo.o for a 2.4 kernel or -+ -+ # insmod mini_fo.ko for a 2.6 kernel -+ -+ -+create a storage dir in tmp and a mountpoint for mini_fo: -+ -+ # mkdir /tmp/sto -+ # mkdir /mnt/mini_fo -+ -+and mount the mini_fo file system: -+ -+ # mount -t mini_fo -o base=/mnt/cdrom,sto=/tmp/sto /mnt/cdrom /mnt/mini_fo -+ -+ -+Now the data stored on the cd can be accessed via the mini_fo -+mountpoint just like any read-write file system, files can be modified -+and deleted, new ones can be created and so on. When done unmount the -+file system: -+ -+ # unmount /mnt/mini_fo -+ -+Note that if the file system is mounted again using the same storage -+file system, of course it will appear in the modified state again. If -+you remount it using an new empty storage directory, it will be -+unmodified. Therefore by executing: -+ -+ # cd /tmp/sto -+ # rm -rf * -+ -+you can nuke all the changes you made to the original file system. But -+ remember NEVER do this while the mini_fo file system is mounted! -+ -+ -+Alternatively you can use the mini_fo-overlay bash script, that -+simplifies managing mini_fo mounts. See TOOLS Section. -+ -+ -+TOOLS -+----- -+ -+mini_fo-merge (experimental): -+ -+This is a bash script that will merge changes contained in the storage -+directory back to the base directory. This allows mini_fo to function -+as a cache file system by overlaying a slow (network, ...) file system -+and using a fast (ramdisk, ...) as storage. When done, changes can be -+merged back to the (slow) base with mini_fo-merge. See "mini_fo-merge -+-h" for details. -+ -+It can be usefull for merging changes back after a successfull test -+(patches, software updates...) -+ -+ -+mini_fo-overlay: -+ -+This bash script simplifies managing one or more mini_fo mounts. For -+overlaying a directory called "basedir1", you can just call: -+ -+ # mini_fo-overlay basedir1 -+ -+This will mount mini_fo with "basedir1" as base, "/tmp/sto-basedir1/" -+as storage to "/mnt/mini_fo-basedir1/". It has more options though, -+type "mini_fo-overlay -h" for details. -+ -+ -+DOCUMENTATION, REPORTING BUGS, GETTING HELP -+------------------------------------------- -+ -+Please visit the mini_fo project page at: -+ -+http://www.denx.de/twiki/bin/view/Know/MiniFOHome -+ -+ -+WARNINGS -+-------- -+ -+Never modify the base or the storage directorys while the mini_fo -+file system is mounted, or you might crash you system. Simply accessing -+and reading should not cause any trouble. -+ -+Exporting a mini_fo mount point via NFS has not been tested, and may -+or may not work. -+ -+Check the RELEASE_NOTES for details on bugs and features. -+ -+ -+ -+Copyright (C) 2004, 2005 Markus Klotzbuecher <mk@creamnet.de> -+ -+This program is free software; you can redistribute it and/or -+modify it under the terms of the GNU General Public License -+as published by the Free Software Foundation; either version -+2 of the License, or (at your option) any later version. -+ -+ ---- /dev/null -+++ b/fs/mini_fo/RELEASE_NOTES -@@ -0,0 +1,111 @@ -+Release: mini_fo-0.6.1 (v0-6-1) -+Date: 21.09.2005 -+ -+ -+Changes: -+-------- -+v0-6-1: -+ -+- bugfixes (see ChangeLog) -+ -+- two helper scripts "mini_fo_merge" and "mini_fo_overlay" (see -+ README for details). -+ -+v0-6-0: -+ -+- Support for 2.4 and 2.6 (see Makefile) -+ -+- Partial hard link support (creating works as expected, but already -+ existing links in the base file system will be treated as if they -+ were individual files). -+ -+- Various bugfixes and cleanups. -+ -+ -+v0-6-0-pre1: -+ -+- This is mini_fo-0-6-0-pre1! This release is a complete rewrite of -+ many vital mini_fo parts such as the old whiteout list code which -+ has been replaced by the new META subsystem. -+ -+- Light weight directory renaming implemented. This means if a -+ directory is renamed via the mini_fo filesystem this will no longer -+ result in a complete copy in storage, instead only one empty -+ directory will be created. All base filed contained in the original -+ directory stay there until modified. -+ -+- Special files (creating, renaming, deleting etc.) now working. -+ -+- Many bugfixes and cleanup, mini_fo is now a lot more stable. -+ -+ -+v0-5-10: -+ -+- Final release of the 0-5-* versions. Next will be a complete rewrite -+ of many features. This release contains several bugfixes related to -+ directory renaming. -+ -+ -+v0-5-10-pre6: -+ -+- Lots of cleanup and several bugfixes related to directory deleting -+ -+- Directory renaming suddenly works, what is most likely due to the -+ fact tha that "mv" is smart: if the classic rename doesn't work it -+ will assume that source and target file are on different fs and will -+ copy the directory and try to remove the source directory. Until -+ directory removing wasn't implemented, it would fail to do this and -+ rollback. -+ So, directory renaming works for now, but it doesn't yet do what you -+ would expect from a overlay fs, so use with care. -+ -+ -+v0-5-10-pre5: -+ -+- implemented directory deleting -+- made parsing of mount options more stable -+- New format of mount options! (See README) -+- I can't reproduce the unknown panic with 2.4.25 anymore, so I'll -+ happily assume it never existed! -+ -+ -+Implemented features: -+--------------------- -+ -+- creating hard links (see BUGS on already existing hard links) -+- lightweight directory renaming -+- renaming device files, pipes, sockets, etc. -+- creating, renaming, deleting of special files -+- deleting directorys -+- general directory reading (simple "ls" ) -+- creating files in existing directorys -+- creating directorys -+- renaming files. -+- reading and writing files (involves opening) -+- appending to files (creates copy in storage) -+- deleting files -+- llseek works too, what allows editors to work -+- persistency (a deleted file stay deleted over remounts) -+- use of symbolic links -+- creating of device files -+ -+ -+Not (yet) implemented features: -+------------------------------- -+ -+- full hard link support. -+ -+ -+ -+BUGS: -+----- -+ -+Hard links in the base file system will be treated as individual -+files, not as links to one inode. -+ -+The main problem with hard links isn't allowing to create them, but -+their pure existence. If you modify a base hard link, the changes made -+will only show up on this link, the other link will remain in the -+original state. I hope to fix this someday. Please note that this does -+not effect the special hard links '.' and '..', that are handled -+seperately by the lower fs. ---- /dev/null -+++ b/fs/mini_fo/state.c -@@ -0,0 +1,620 @@ -+/* -+ * Copyright (C) 2005 Markus Klotzbuecher <mk@creamnet.de> -+ * -+ * This program is free software;

TIF_RESTORE_SIGMASK/pselect6/ppoll/epoll_pwait - -This patch adds support for TIF_RESTORE_SIGMASK to ARM's -signal handling, which allows to hook up the pselect6, ppoll, -and epoll_pwait syscalls on ARM. - -Tested here with eabi userspace and a test program with a -deliberate race between a child's exit and the parent's -sigprocmask/select sequence. Using sys_pselect6() instead -of sigprocmask/select reliably prevents the race. - -The other arch's support for TIF_RESTORE_SIGMASK has evolved -over time: - -In 2.6.16: -- add TIF_RESTORE_SIGMASK which parallels TIF_SIGPENDING -- test both when checking for pending signal [changed later] -- reimplement sys_sigsuspend() to use current->saved_sigmask, - TIF_RESTORE_SIGMASK [changed later], and -ERESTARTNOHAND; - ditto for sys_rt_sigsuspend(), but drop private code and - use common code via __ARCH_WANT_SYS_RT_SIGSUSPEND; -- there are now no "extra" calls to do_signal() so its oldset - parameter is always ¤t->blocked so need not be passed, - also its return value is changed to void -- change handle_signal() to return 0/-errno -- change do_signal() to honor TIF_RESTORE_SIGMASK: - + get oldset from current->saved_sigmask if TIF_RESTORE_SIGMASK - is set - + if handle_signal() was successful then clear TIF_RESTORE_SIGMASK - + if no signal was delivered and TIF_RESTORE_SIGMASK is set then - clear it and restore the sigmask -- hook up sys_pselect6() and sys_ppoll() - -In 2.6.19: -- hook up sys_epoll_pwait() - -In 2.6.26: -- allow archs to override how TIF_RESTORE_SIGMASK is implemented; - default set_restore_sigmask() sets both TIF_RESTORE_SIGMASK and - TIF_SIGPENDING; archs need now just test TIF_SIGPENDING again - when checking for pending signal work; some archs now implement - TIF_RESTORE_SIGMASK as a secondary/non-atomic thread flag bit -- call set_restore_sigmask() in sys_sigsuspend() instead of setting - TIF_RESTORE_SIGMASK - -In 2.6.29-rc: -- kill sys_pselect7() which no arch wanted - -So for 2.6.31-rc6/ARM this patch does the following: -- Add TIF_RESTORE_SIGMASK. Use the generic set_restore_sigmask() - which sets both TIF_SIGPENDING and TIF_RESTORE_SIGMASK, so - TIF_RESTORE_SIGMASK need not claim one of the scarce low thread - flags, and existing TIF_SIGPENDING and _TIF_WORK_MASK tests need - not be extended for TIF_RESTORE_SIGMASK. -- sys_sigsuspend() is reimplemented to use current->saved_sigmask - and set_restore_sigmask(), making it identical to most other archs -- The private code for sys_rt_sigsuspend() is removed, instead - generic code supplies it via __ARCH_WANT_SYS_RT_SIGSUSPEND. -- sys_sigsuspend() and sys_rt_sigsuspend() no longer need a pt_regs - parameter, so their assembly code wrappers are removed. -- handle_signal() is changed to return 0 on success or -errno. -- The oldset parameter to do_signal() is now redundant and removed, - and the return value is now also redundant and changed to void. -- do_signal() is changed to honor TIF_RESTORE_SIGMASK: - + get oldset from current->saved_sigmask if TIF_RESTORE_SIGMASK - is set - + if handle_signal() was successful then clear TIF_RESTORE_SIGMASK - + if no signal was delivered and TIF_RESTORE_SIGMASK is set then - clear it and restore the sigmask -- Hook up sys_pselect6, sys_ppoll, and sys_epoll_pwait. - -Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> -Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> ---- -
