kernel/audit.c control character detection is off-by-one
Hello,
According to my understanding there is an off-by-one bug in the
function:
audit_string_contains_control()
in:
kernel/audit.c
Patch is included.
I do not know from how many places the function is called from, but for
example, SELinux Access Vector Cache tries to log untrusted filenames via
call path:
If audit_string_contains_control() detects control characters, then the
string is hex-encoded. But the hex=0x7f dec=127, DEL-character, is not
detected.
I guess this could have at least some minor security implications, since a
user can create a filename with 0x7f in it, causing logged filename to
possibly look different when someone reads it on the terminal.

causing NAND chips not being initialised on several ARM boards.

All *MTD_NAND_AT91* where renamed to *MTD_NAND_ATMEL* in order

This patch was only tested on a MACH_SAM9_L9260, as this is the

The iov_iter_advance() function would look at the iov->iov_len entry
even though it might have iterated over the whole array, and iov was
pointing past the end. This would cause DEBUG_PAGEALLOC to trigger a
kernel page fault if the allocation was at the end of a page, and the
next page was unallocated.
The quick fix is to just change the order of the tests: check that there
is any iovec data left before we check the iov entry itself.

[MIPS] kgdb: Remove existing implementation
This patch explicitly removes the kgdb implementation, for mips which
is intended to be followed by a patch that adds a kgdb implementation
for MIPS that makes use of the kgdb core in the kernel.

* Random cleanups spotted by checkpatch script.
* Do not initialize panic_timeout. "panic=" kernel parameter can be used.
* Do not add "ip=any" or "ip=bootp". This options is not board specific.
* Do not add "root=/dev/nfs". This is default on CONFIG_ROOT_NFS.
* Kill unused error checking.
* Fix IRQ comment to match current code.
* Kill some unneeded includes
* ST0_ERL is already cleared in generic code.
* conswitchp is initialized generic code.
* __init is not needed in prototype.

[MIPS] Initialization of Alchemy boards
An earlier update changed some calls from simple_strotl to strict_strtol but
did not account for the differences in the syntax between the calls.
simple_strotl returns the integer; strict_strtol returns an error code and
takes a pointer to the result. As it was, NULL was being passed in place of
the result, which led to failures during kernel initialization when using
YAMON.

Bug originally found and reported by Julia Lawall <julia@diku.dk>. I
decieded that the whole error check was mostly useless paranoia and should
be discarded. It would only ever trigger if r3k_have_wired_reg has a wrong
value.
