+@@@ SLUB kmalloc-8: Restoring redzone (0xcc) from 0xc90f6d28-0xc90f6d2b
+
+
+
+If SLUB encounters a corrupted object then it will perform the following
+actions:
+
+1. Isolation and report of the issue
+
+This will be a message in the system log starting with
+
+*** SLUB <slab cache affected>: <What went wrong>@<object address>
+offset=<offset of object into slab> flags=<slabflags>
+inuse=<objects in use in this slab> freelist=<first free object in slab>
+
+2. Report on how the problem was dealt with in order to ensure the continued
+operation of the system.
+
+These are messages in the system log beginning with
+
+@@@ SLUB <slab cache affected>: <corrective action taken>
+
+
+In the above sample SLUB found that the Redzone of an active object has
+been overwritten. Here a string of 8 characters was written into a slab that
+has the length of 8 characters. However, a 8 character string needs a
+terminating 0. That zero has overwritten the first byte of the Redzone field.
+After reporting the details of the issue encountered the @@@ SLUB message
+tell us that SLUB has restored the redzone to its proper value and then
+system operations continue.
+
+Various types of lines can follow the @@@ SLUB line:
+
+Bytes b4 <address> : <bytes>
+ Show a few bytes before the object where the problem was detected.
+ Can be useful if the corruption does not stop with the start of the
+ object.
+
+Object <address> : <bytes>
+ The bytes of the object. If the object is inactive then the bytes
+ typically contain poisoning values. Any non-poison value shows a
+ corruption by a write after free.
+
+Redzone <address> : <bytes>
+ The redzone following the object. The redzone is used to detect
+ writes after the object. All bytes should always have the same
+ value. If there is any deviation then it is due to a write after
+ the object boundary.
+
+Freepointer
+ The pointer to the next free object in the slab. May become
+ corrupted if overwriting continues after the red zone.
+
+Last alloc:
+Last free:
+ Shows the address from which the object was allocated/freed last.
+ We note the pid, the time and the CPU that did so. This is usually
+ the most useful information to figure out where things went wrong.
+ Here get_modalias() did an kmalloc(8) instead of a kmalloc(9).
+
+Filler <address> : <bytes>
+ Unused data to fill up the space in order to get the next object
+ properly aligned. In the debug case we make sure that there are
+ at least 4 bytes of filler. This allow for the detection of writes
+ before the object.
+
+Following the filler will be a stackdump. That stackdump describes the
+location where the error was detected. The cause of the corruption is more
+likely to be found by looking at the information about the last alloc / free.

[FIXME -- better explanations]
-Implementations in the current drivers in the kernel tree:
-
-Here I have tried to summarize what the different drivers support and
-where they do strange things compared to the other drivers.
-
-acquirewdt.c -- Acquire Single Board Computer
-
- This driver has a hardcoded timeout of 1 minute
-
- Supports CONFIG_WATCHDOG_NOWAYOUT
-
- GETSUPPORT returns KEEPALIVEPING. GETSTATUS will return 1 if
- the device is open, 0 if not. [FIXME -- isn't this rather
- silly? To be able to use the ioctl, the device must be open
- and so GETSTATUS will always return 1].
-
-advantechwdt.c -- Advantech Single Board Computer
-
- Timeout that defaults to 60 seconds, supports SETTIMEOUT.
-
- Supports CONFIG_WATCHDOG_NOWAYOUT
-
- GETSUPPORT returns WDIOF_KEEPALIVEPING and WDIOF_SETTIMEOUT.
- The GETSTATUS call returns if the device is open or not.
- [FIXME -- silliness again?]
-
-booke_wdt.c -- PowerPC BookE Watchdog Timer
-
- Timeout default varies according to frequency, supports
- SETTIMEOUT
-
- Watchdog cannot be turned off, CONFIG_WATCHDOG_NOWAYOUT
- does not make sense
-
- GETSUPPORT returns the watchdog_info struct, and
- GETSTATUS returns the supported options. GETBOOTSTATUS
- returns a 1 if the last reset was caused by the
- watchdog and a 0 otherwise. This watchdog cannot be
- disabled once it has been started. The wdt_period kernel
- parameter selects which bit of the time base changing
- from 0->1 will trigger the watchdog exception. Changing
- the timeout from the ioctl calls will change the
- wdt_period as defined above. Finally if you would like to
- replace the default Watchdog Handler you can implement the
- WatchdogHandler() function in your own code.
-
-eurotechwdt.c -- Eurotech CPU-1220/1410
-
- The timeout can be set using the SETTIMEOUT ioctl and defaults
- to 60 seconds.
-
- Also has a module parameter "ev", event type which controls
- what should happen on a timeout, the string "int" or anything
- else that causes a reboot. [FIXME -- better description]
-
- Supports CONFIG_WATCHDOG_NOWAYOUT
-
- GETSUPPORT returns CARDRESET and WDIOF_SETTIMEOUT but
- GETSTATUS is not supported and GETBOOTSTATUS just returns 0.
-
-i810-tco.c -- Intel 810 chipset
-
- Also has support for a lot of other i8x0 stuff, but the
- watchdog is one of the things.
-
- The timeout is set using the module parameter "i810_margin",
- which is in steps of 0.6 seconds where 2<i810_margin<64. The
- driver supports the SETTIMEOUT ioctl.
-
- Supports CONFIG_WATCHDOG_NOWAYOUT.
-
- GETSUPPORT returns WDIOF_SETTIMEOUT. The GETSTATUS call
- returns some kind of timer value which ist not compatible with
- the other drivers. GETBOOT status returns some kind of
- hardware specific boot status. [FIXME -- describe this]
-
-ib700wdt.c -- IB700 Single Board Computer
-
- Default timeout of 30 seconds and the timeout is settable
- using the SETTIMEOUT ioctl. Note that only a few timeout
- values are supported.
-
- Supports CONFIG_WATCHDOG_NOWAYOUT
-
- GETSUPPORT returns WDIOF_KEEPALIVEPING and WDIOF_SETTIMEOUT.
- The GETSTATUS call returns if the device is open or not.
- [FIXME -- silliness again?]
-
-machzwd.c -- MachZ ZF-Logic
-
- Hardcoded timeout of 10 seconds
-
- Has a module parameter "action" that controls what happens
- when the timeout runs out which can be 0 = RESET (default),
- 1 = SMI, 2 = NMI, 3 = SCI.
-
- Supports CONFIG_WATCHDOG_NOWAYOUT and the magic character

- this works, there seems to be some magic connected to
- CONFIG_WATCHDOG_NOWAYOUT]
-
-pcwd.c -- Berkshire PC Watchdog
-
- Hardcoded timeout of 1.5 seconds
-
- Supports CONFIG_WATCHDOG_NOWAYOUT
-
- GETSUPPORT returns WDIOF_OVERHEAT|WDIOF_CARDRESET and both
- GETSTATUS and GETBOOTSTATUS return something useful.
-
- The SETOPTIONS call can be used to enable and disable the card
- and to ask the driver to call panic if the system overheats.

- Watchdog Timer Interfaces For The Linux Operating System
-
- Alan Cox <alan@lxorguk.ukuu.org.uk>
-
- Custom Linux Driver And Program Development
-
-
-The following watchdog drivers are currently implemented:
-
- ICS WDT501-P
- ICS WDT501-P (no fan tachometer)
- ICS WDT500-P
- Software Only
- SA1100 Internal Watchdog
- Berkshire Products PC Watchdog Revision A & C (by Ken Hollis)
-
-
-All six interfaces provide /dev/watchdog, which when open must be written
-to within a timeout or the machine will reboot. Each write delays the reboot
-time another timeout. In the case of the software watchdog the ability to
-reboot will depend on the state of the machines and interrupts. The hardware
-boards physically pull the machine down off their own onboard timers and
-will reboot from almost anything.
-
-A second temperature monitoring interface is available on the WDT501P cards
-and some Berkshire cards. This provides /dev/temperature. This is the machine
-internal temperature in degrees Fahrenheit. Each read returns a single byte
-giving the temperature.
-
-The third interface logs kernel messages on additional alert events.
-
-Both software and hardware watchdog drivers are available in the standard
-kernel. If you are using the software watchdog, you probably also want
-to use "panic=60" as a boot argument as well.
-
-The wdt card cannot be safely probed for. Instead you need to pass
-wdt=ioaddr,irq as a boot parameter - eg "wdt=0x240,11".
-
-The SA1100 watchdog module can be configured with the "sa1100_margin"
-commandline argument which specifies timeout value in seconds.
-
-The i810 TCO watchdog modules can be configured with the "i810_margin"
-commandline argument which specifies the counter initial value. The counter
-is decremented every 0.6 seconds and default to 50 (30 seconds). Values can
-range between 3 and 63.
-
-The i810 TCO watchdog driver also implements the WDIOC_GETSTATUS and
-WDIOC_GETBOOTSTATUS ioctl()s. WDIOC_GETSTATUS returns the actual counter value
-and WDIOC_GETBOOTSTATUS returns the value of TCO2 Status Register (see Intel's
-documentation for the 82801AA and 82801AB datasheet).
