We can simply wrap in to the dev_set/get_drvdata(), there's no reason
to track an extra level of private data on top of the struct device.

[PATCH] Fix the bug of using AUDIT_STATUS_RATE_LIMIT when set fail, no error output.

When the "status_get->mask" is "AUDIT_STATUS_RATE_LIMIT || AUDIT_STATUS_BACKLOG_LIMIT".
If "audit_set_rate_limit" fails and "audit_set_backlog_limit" succeeds, the "err" value
will be greater than or equal to 0. It will miss the failure of rate set.

11 years agokernel/audit.c control character detection is off-by-one
Vesa-Matti J Kari [Tue, 22 Jul 2008 21:06:13 +0000]
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:

avc_audit()
     audit_log_untrustedstring()
         audit_log_n_untrustedstring()
             audit_string_contains_control()

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.

[PATCH 1/2] proc: fix inode number bogorithmetic

Id which proc gets from IDR for inode number and id which proc removes
from IDR do not match. E.g. 0x11a transforms into 0x8000011a.

Which stayed unnoticed for a long time because, surprise, idr_remove()
masks out that high bit before doing anything.

All of this due to "| ~MAX_ID_MASK" in release_inode_number().

I still don't understand how it's supposed to work, because "| ~MASK"
is not an inversion for "& MAX" operation.

So, use just one nice, working addition. Make start offset unsigned int,

For hiper socket devices this patch will economize the reallocation
of the tx skb data segment by allocating separate memory for the qdio
transport information (qeth header).

[S390] Optimize storage key operations for anon pages

For anonymous pages without a swap cache backing the check in
page_remove_rmap for the physical dirty bit in page_remove_rmap is
unnecessary. The instructions that are used to check and reset the dirty
bit are expensive. Removing the check noticably speeds up process exit.
In addition the clearing of the dirty bit in __SetPageUptodate is
pointless as well. With these two changes there is no storage key
operation for an anonymous page anymore if it does not hit the swap
space.

The micro benchmark which repeatedly executes an empty shell script
gets about 5% faster.

[S390] nohz/sclp: disable timer on synchronous waits.

sclp_sync_wait wait synchronously for an sclp interrupt and disables
timer interrupts. However on the irq enter paths there is an extra
check if a timer interrupt would be due and calls the timer callback.
This would schedule softirqs in the wrong context.
So introduce local_tick_enable/disable which prevents this.

Pieter du Preez [Fri, 1 Aug 2008 09:06:40 +0000]
Fix rename of at91_nand -> atmel_nand

Structs called at91_nand_data where renamed to atmel_nand_data
and configs called *MTD_NAND_AT91* where renamed to
*MTD_NAND_ATMEL*. This was unfortunately not done consistently,
causing NAND chips not being initialised on several ARM boards.

I am aware that the author of the original change did not rename
MTD_NAND_AT91_BUSWIDTH to MTD_NAND_ATMEL_BUSWIDTH, for example.
All *MTD_NAND_AT91* where renamed to *MTD_NAND_ATMEL* in order
to keep naming consistency.

This patch was only tested on a MACH_SAM9_L9260, as this is the
only ARM board I have to my disposal.

Before this patch:

$ git-ls-files |xargs grep atmel_nand |wc -l
105
$ git-ls-files |xargs grep at91_nand |wc -l

8
$ git-ls-files |xargs grep MTD_NAND_AT91 |wc -l

$ git-ls-files |xargs grep at91_nand |wc -l

Fix off-by-one error in iov_iter_advance()

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.

Thanks to Alexey Dobriyan for finding this case, and testing the fix.

We zero-fill them like we are supposed to, and that's all fine.  It's

actually filled from the filesystem.
