* PM: add kconfig option for deprecated .../power/state filesDavid Brownell2006-09-251-0/+11
| | | | | | | | | | | | Add a new PM_SYSFS_DEPRECATED config option to control whether or not the /sys/devices/.../power/state files are provided. This will make it easier to get rid of that mechanism when the time comes, and to verify that userspace tools work right without it.

* [PATCH] prevent swsusp with PAEPavel Machek2006-09-061-1/+5
| | | | | | | | | | PAE + swsusp results in hard-to-debug crash about 50% of time during resume. Cause is known, fix needs to be ported from x86-64 (but we can't make it to 2.6.18, and I'd like this to be worked around in 2.6.18).

| | | | | | | | | | CONFIG_PM_TRACES scrogs your RTC. Mark it as experimental, and defaulting to `off'. Also beef up the help message a bit. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* Fix PM_TRACE dependency: works only on 32-bit x86 for nowLinus Torvalds2006-06-251-1/+1
| | | | | | | | Not that x86-64 and other architecture support should be difficult to add (trivial fixups to the data format and add the proper linker script entry). Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* Add some basic resume trace facilitiesLinus Torvalds2006-06-241-0/+9
| | | | | | | | | | Considering that there isn't a lot of hw we can depend on during resume, this is about as good as it gets. This is x86-only for now, although the basic concept (and most of the code) will certainly work on almost any platform. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* help text: SOFTWARE_SUSPEND doesn't need ACPIAdrian Bunk2006-04-011-1/+1

| * [PATCH] encrypt suspend data for easy wipingAndreas Steinmetz2005-09-051-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch protects from leaking sensitive data after resume from suspend. During suspend a temporary key is created and this key is used to encrypt the data written to disk. When, during resume, the data was read back into memory the temporary key is destroyed which simply means that all data written to disk during suspend are then inaccessible so they can't be stolen lateron. Think of the following: you suspend while an application is running that keeps sensitive data in memory. The application itself prevents the data from being swapped out. Suspend, however, must write these data to swap to be able to resume lateron. Without suspend encryption your sensitive data are then stored in plaintext on disk. This means that after resume your sensitive data are accessible to all applications having direct access to the swap device which was used for suspend. If you don't need swap after resume these data can remain on disk virtually forever. Thus it can happen that your system gets broken in weeks later and sensitive data which you thought were encrypted and protected are retrieved and stolen from the swap device.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+74
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
