Hi List,
I have a few queries regarding slab memory and it's usage.
I have seen slab cache increase by even 1GB, over two to three days on a
stable system.(The system was sending and receiving bulk amounts of
packets).
When is slab usually freed? Also when I analyzed /proc/slabinfo, I was
hi all,
i read somewhere that there is no floating point arithmatic supported in the
kernel space . is it true??
but the floating point registers and even floating point arithmatic units
are all handled by the.( kernel i think).
thanks in advance for help...

That is correct. In some architectures, attempts to use floating point
from the kernel will work. I've seen some x86 code that uses it.

Hi,
I recently read about the Linux kernel implementing ASLR to prevent buffer
overflow attacks.
nope...that is done to make symbol address guessing harder
I would like to have a look at how this is
Please reply all..I added back list.

thnx john,.
but i know that this indicates to compiler to align the structure to its
nearest boundries. is that so?
I am not sure of your definition of boundary, but I

i have seen many places in kernel where the variables specially the
structures should be of fixed size independent of the architecture. i went
through the definitions of them but dint get clearly (or frankly say
...dint get them even a bit) .

I'm not sure whether we are
Dear All,
I have a kernel module which i want to add to kernel permanently(I was
doing it dynamically) .
How can we achieve this ?

A nice kernel document regarding unaligned memory access. It may not
be directly answering all the questions asked, but once gone through
and understood completely, it will become easy to figure out how to
write portable kernel code.

Hi,
zfs_mknode is the function use by mknod syscall to create device special
file
in solaris kernel. I traverse the code and just found how they stores the
minor number
which is in znode's(disk inode of Linux) attributes struct called
sa_bulk_attr field
uint16_t sa_buftype which is of 16bit only.
