+Subject: [SCSI] sd,sr: add early detection of medium not present
+X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commitdiff_plain;h=001aac257cf8adbe90cdcba6e07f8d12dfc8fa6b
+
+[SCSI] sd,sr: add early detection of medium not present
+
+The current scsi_test_unit_ready() is updated to return sense code
+information (in struct scsi_sense_hdr).  The sd and sr drivers are
+changed to interpret the sense code return asc 0x3a as no media and
+adjust the device status accordingly.

+[SCSI] sr: update to follow tray status correctly
+
+Based on an original patch from: David Martin <tasio@tasio.net>
+
+When trying to get the drive status via ioctl CDROM_DRIVE_STATUS, with
+no disk it gives CDS_TRAY_OPEN even if the tray is closed.
+
+ioctl works as expected with ide-cd driver.

+[SCSI] sr: fix test unit ready responses
+
+Commit 210ba1d1724f5c4ed87a2ab1a21ca861a915f734 updated sr.c to use
+the scsi_test_unit_ready() function.  Unfortunately, this has the
+wrong characteristic of eating NOT_READY returns which sr.c relies on
+for tray status.
+
+Fix by rolling an internal sr_test_unit_ready() that doesn't do this.

++ACPI Custom DSDT read from initramfs
++
++2003 by Markuss Gaugusch < dsdt at gaugusch dot org >
++Special thanks go to Thomas Renninger from SuSE, who updated the patch for
++2.6.0 and later modified it to read inside initramfs
++2004 - 2007 maintained by Eric Piel < eric dot piel at tremplin-utc dot net >
++
++This option is intended for people who would like to hack their DSDT and don't want
++to recompile their kernel after every change. It can also be useful to distros
++which offers pre-compiled kernels and want to allow their users to use a
++modified DSDT. In the Kernel config, enable the initial RAM filesystem support
++(in Device Drivers|Block Devices) and enable ACPI_CUSTOM_DSDT_INITRD at the ACPI
++options (General Setup|ACPI Support|Read custom DSDT from initrd).
++
++A custom DSDT (Differentiated System Description Table) is useful when your
++computer uses ACPI but problems occur due to broken implementation. Typically,
++your computer works but there are some troubles with the hardware detection or
++the power management. You can check that troubles come from errors in the DSDT by
++activating the ACPI debug option and reading the logs. This table is provided
++by the BIOS, therefore it might be a good idea to check for BIOS update on your
++vendor website before going any further. Errors are often caused by vendors
++testing their hardware only with Windows or because there is code which is
++executed only on a specific OS with a specific version and Linux hasn't been
++considered during the development.
++
++Before you run away from customising your DSDT, you should note that already
++corrected tables are available for a fair amount of computers on this web-page:
++http://acpi.sf.net/dsdt . If you are part of the unluckies who cannot find
++their hardware in this database, you can modify your DSDT by yourself. This
++process is less painful than it sounds. Download the Intel ASL 
++compiler/decompiler at http://www.intel.com/technology/IAPC/acpi/downloads.htm .
++As root, you then have to dump your DSDT and decompile it. By using the
++compiler messages as well as the kernel ACPI debug messages and the reference book
++(available at the Intel website and also at http://www.acpi.info), it is quite
++easy to obtain a fully working table.
++
++Once your new DSDT is ready you'll have to add it to an initrd so that the
++kernel can read the table at the very beginning of the boot. As the file has
++to be accessed very early during the boot process the initrd has to be an
++initramfs. The file is contained into the initramfs under the name /DSDT.aml .
++To obtain such an initrd, you might have to modify your mkinitrd script or you
++can add it later to the initrd with the script appended to this document. The
++command will look like:
++initrd-add-dsdt initrd.img my-dsdt.aml
++
++In case you don't use any initrd, the possibilities you have are to either start
++using one (try mkinitrd or yaird), or use the "Include Custom DSDT" configure
++option to directly include your DSDT inside the kernel.
++
++The message "Looking for DSDT in initramfs..." will tell you if the DSDT was
++found or not. If you need to update your DSDT, generate a new initrd and
++perform the steps above. Don't forget that with Lilo, you'll have to re-run it.
++

+drm: Fix spinlock race condition that can lockup the kernel
+
+From: Mike Isely <isely@pobox.com>
+
+The i915_vblank_swap() function schedules an automatic buffer swap
+upon receipt of the vertical sync interrupt.  Such an operation is
+lengthy so it can't happen normal interrupt context, so the DRM
+implements this by scheduling the work in a kernel softirq-scheduled
+tasklet.  In order for the buffer swap to work safely, the DRM's
+central lock must be taken, via a call to drm_lock_take() in drm_irq.c
+within the function drm_locked_tasklet_func().  The lock-taking logic
+uses a non-interrupt-blocking spinlock to implement the manipulations
+needed to take the lock.  Note that a non-interrupt-blocking spinlock
+blocks kernel pre-emption and atomically sets a flag, but interrupts
+are still enabled.  This semantic is safe if ALL attempts to use the
+spinlock only happen from process context.  However this buffer swap
+happens from softirq context which is really a form of interrupt
+context that WILL pre-empt execution even when normal thread
+pre-emption is otherwise disabled.  Thus we have an unsafe situation,
+in that drm_locked_tasklet_func() can block on a spinlock already
+taken by a thread in process context which will never get scheduled
+again because of the blocked softirq tasklet.  This wedges the kernel
+hard.
+
+It's a very small race condition, but a race nonetheless with a very
+undesirable potential outcome.  To trigger this bug, run a dual-head
+cloned mode configuration which uses the i915 drm, then execute an
+opengl application which synchronizes buffer swaps against the
+vertical sync interrupt.  In my testing, a lockup always results after
+running anywhere from 5 minutes to an hour and a half.  I believe
+dual-head is needed to really trigger the problem because then the
+vertical sync interrupt handling is no longer predictable (due to
+being interrupt-sourced from two different heads running at different
+speeds).  This raises the probability of a the tasklet trying to run
+while the userspace DRI is doing things to the GPU (and manipulating
+the DRM lock).
+
+The fix is to change the relevant spinlock semantics to be the
+interrupt-blocking form.  Thus all calls for this spinlock change from
+spin_lock() to spin_lock_irqsave() and similarly calls to
+spin_unlock() change to spin_unlock_irqrestore().  After this change I
+am no longer able to trigger the lockup; the longest test run so far
+was 6 hours (test stopped after that point).

+Subject: file capabilities: remove cap_task_kill()
+X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commitdiff_plain;h=aedb60a67c10a0861af179725d060765262ba0fb
+
+file capabilities: remove cap_task_kill()
+
+The original justification for cap_task_kill() was as follows:
+
+	check_kill_permission() does appropriate uid equivalence checks.
+	However with file capabilities it becomes possible for an
+	unprivileged user to execute a file with file capabilities
+	resulting in a more privileged task with the same uid.
+
+However now that cap_task_kill() always returns 0 (permission
+granted) when p->uid==current->uid, the whole hook is worthless,
+and only likely to create more subtle problems in the corner cases
+where it might still be called but return -EPERM.  Those cases
+are basically when uids are different but euid/suid is equivalent
+as per the check in check_kill_permission().
+
+One example of a still-broken application is 'at' for non-root users.
+
+This patch removes cap_task_kill().

++	  Saying Y here includes support for SquashFS 3.3 (a Compressed
++	  Read-Only File System).  Squashfs is a highly compressed read-only
++	  filesystem for Linux.  It uses zlib compression to compress both
++	  files, inodes and directories.  Inodes in the system are very small
++	  and all blocks are packed to minimise data overhead. Block sizes
++	  greater than 4K are supported up to a maximum of 1 Mbytes (default
++	  block size 128K).  SquashFS 3.3 supports 64 bit filesystems and files
++	  (larger than 4GB), full uid/gid information, hard links and timestamps.  
++
++	  Squashfs is intended for general read-only filesystem use, for
++	  archival use (i.e. in cases where a .tar.gz file may be used), and in
++	  embedded systems where low overhead is needed.  Further information
++	  and filesystem tools are available from http://squashfs.sourceforge.net.
++
++	  If you want to compile this as a module ( = code which can be
++	  inserted in and removed from the running kernel whenever you want),
++	  say M here and read <file:Documentation/modules.txt>.  The module
++	  will be called squashfs.  Note that the root file system (the one
++	  containing the directory /) cannot be compiled as a module.

++	  SquashFS uses less memory at the expense of extra reads from disk.
