This patch also provides an extra feature: a validation callback
that could be speaciliazed for other types.
s/speaciliazed/speciliazed/
Will fix.
[ATTR_GOO] = { .type = MYTYPE,
.validation_data = &myvalidation_data,
.validate_content = mycontent_validator },
Indent is wrong. (Does not matter really in desc, but anyway)
I cant find out how it got indented that way; my source
or email dont show it as such (but really doesnt matter).

Will add.

I don't understand why you redefine the struct here. You already have it
defined in the uapi: struct __nla_bit_flags
Just move this (struct nla_bit_flags) to the uapi and remove
__nla_bit_flags ?
I am not sure that will compile since the type is defined in netlink.h
Also, note: uapi uses _u32 and kernel uses u32 as types i.e it is pretty
common approach; i will try to move it to uapi and keep that uapi
format. If it doesnt compile without acrobatics I will keep it as is.
It doesnt compile - I could move it to linux/netlink.h but it seems
so out of place.
so i will keep things as is for now unless you can think of something
else.
First of all, makes no sense to put this struct "struct __nla_bit_flags"
into rtnetlink.h uapi file. This is generic netlink stuff, not specifict
to rtnetlink.
I believe that this struct should go into:
include/uapi/linux/netlink.h
struct nla_flag_bits {
__u32 nla_flag_bits_values;
__u32 nla_flag_bits_selector;
};
Then you can use it from userspace and everywhere in kernel.
That file seems to be very out of place for this stuff.
Btw, I find it very odd that enum containling NLA_* like NLA_U32 and
others is not part of uapi file and is rather defined in
include/net/netlink.h. Any idea why?
NLA_XXX are kernel side types. They are part of net/netlink.h which is
not uapi accessible.
David Ahern has submitted a patch to move all those defines to iproute2.
Will make sense to move these to a uapi/linux/netlink-types.h but that
is waay beyond the scope of this patch set.
cheers,
