Hi, all.
I have found something very strange to me... It is a problem with static
allocating size of buffer where jail param is going to be coppied, using
jail_getv function from the libjails. Well for example:
buff[size];
jail_getv(0, "name", "1", "host.hostname", buff, NULL);
the result for si
Hi,
I want to allocate one (or more) pages in kernel space.
I'm not sure what is the api in freebsd (something which
is similar to __get_free_pages() of linux).
Would malloc(4096, ...) guarantee that the returned
address is aligned on page boundary?
Thanks and regards,
-Kalash

Hello,
what about using contigmalloc(9), there you can specify
alignment and boundary.

No, it's not completely identical.
__start_SECNAME placement would be identical, but our ld would still assign the

Unfortunately, one can easily miss such problems during build of the module.
I'm working on a system which consists of lots of user-space programs
and kernel modules and
uses it's own complicated build system.
gcc option -Werror is not used by the build system (I believe it
should), that's why we j
