So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes
on 64bit architectures, allowing us to combine the 4 bytes hole left by the
layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4
64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN...
:-)
Many calculations that previously required that skb->{transport,network,
mac}_header be first converted to a pointer now can be done directly, being
meaningful as offsets or pointers.

Johannes Berg discovered that kernel space was leaking to
userspace on 64 bit platform. He made a first patch to fix that. This
is an improved version of his patch.

Many struct file_operations in the kernel can be "const". Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data. In addition it'll catch accidental writes at compile time to
these shared resources.

I believe all the below memory barriers only matter on SMP so
therefore the smp_* variant of the barrier should be used.
I'm wondering if the barrier in net/ipv4/inet_timewait_sock.c should be
dropped entirely. schedule_work's implementation currently implies a
memory barrier and I think sane semantics of schedule_work() should imply
a memory barrier, as needed so the caller shouldn't have to worry.
It's not quite obvious why the barrier in net/packet/af_packet.c is
needed; maybe it should be implied through flush_dcache_page?

WE-21 changed the ABI for the SIOC[SG]IW{ESSID,NICKN} ioctls by dropping
NULL termination. This patch adds compatibility code so that WE-21 can
work properly with WE-20 (and older) tools.

This is version 21 of the Wireless Extensions. Changelog :
o finishes migrating the ESSID API (remove the +1)
o netdev->get_wireless_stats is no more
o long/short retry
This is a redacted version of a patch originally submitted by Jean
Tourrilhes. I removed most of the additions, in order to minimize
future support requirements for nl80211 (or other WE successor).

Drivers expect to be able to call wireless_send_event in arbitrary
contexts. On the other hand, netlink really doesn't like being
invoked in an IRQ context. So we need to postpone the sending of
netlink skb's to a tasklet.

I've just realised that the RtNetlink code does not check the
permission for SIOCGIWENCODE and SIOCGIWENCODEEXT, which means that
any user can read the encryption keys. The fix is trivial and should
go in 2.6.17 alonside the two other patch I sent you last week.

This is version 20 of the Wireless Extensions. This is the
completion of the RtNetlink work I started early 2004, it enables the
full Wireless Extension API over RtNetlink.
Few comments on the patch :
o totally driver transparent, no change in drivers needed.
o iwevent were already RtNetlink based since they were created
(around 2.5.7). This adds all the regular SET and GET requests over
RtNetlink, using the exact same mechanism and data format as iwevents.
o This is a Kconfig option, as currently most people have no
need for it. Surprisingly, patch is actually small and well
encapsulated.
o Tested on SMP, attention as been paid to make it 64 bits clean.
o Code do probably too many checks and could be further
optimised, but better safe than sorry.
o RtNetlink based version of the Wireless Tools available on
my web page for people inclined to try out this stuff.
I would also like to thank Alexey Kuznetsov for his helpful
suggestions to make this patch better.

Although this message is having the intended effect of causing wireless
driver maintainers to upgrade their code, I never should have merged this
patch in its present form. Leading to tons of bug reports and unhappy
users.
Some wireless apps poll for statistics regularly, which leads to a printk()
every single time they ask for stats. That's a little bit _too_ much of a
reminder that the driver is using an old API.
Change this to printing out the message once, per kernel boot.

Hi Jeff,
This is version 19 of the Wireless Extensions. It was supposed
to be the fallback of the WPA API changes, but people seem quite happy
about it (especially Jouni), so the patch is rather small.
The patch has been fully tested with 2.6.13 and various
wireless drivers, and is in its final version. Would you mind pushing
that into Linus's kernel so that the driver and the apps can take
advantage ot it ?
It includes :
o iwstat improvement (explicit dBm). This is the result of
long discussions with Dan Williams, the authors of
NetworkManager. Thanks to him for all the fruitful feedback.
o remove pointer from event stream. I was not totally sure if
this pointer was 32-64 bits clean, so I'd rather remove it and be at
peace with it.
o remove linux header from wireless.h. This has long been
requested by people writting user space apps, now it's done, and it
was not even painful.
o final deprecation of spy_offset. You did not like it, it's
now gone for good.
o Start deprecating dev->get_wireless_stats -> debloat netdev
o Add "check" version of event macros for ieee802.11
stack. Jiri Benc doesn't like the current macros, we aim to please ;-)
All those changes, except the last one, have been bit-roting on
my web pages for a while...
Patches for most kernel drivers will follow. Patches for the
Orinoco and the HostAP drivers have been sent to their respective
maintainers.
Have fun...
Jean

This is version 18 of the Wireless Extensions. The main change
is that it adds all the necessary APIs for WPA and WPA2 support. This
work was entirely done by Jouni Malinen, so let's thank him for both
his hard work and deep expertise on the subject ;-)
This APIs obviously doesn't do much by itself and works in
concert with driver support (Jouni already sent you the HostAP
changes) and userspace (Jouni is updating wpa_supplicant). This is
also orthogonal with the ongoing work on in-kernel IEEE support (but
potentially useful).
The patch is attached, tested with 2.6.11. Normally, I would
ask you to push that directly in the kernel (99% of the patch has been
on my web page for ages and it does not affect non-WPA stuff), but
Jouni convinced me that it should bake a few weeks in wireless-2.6
first, so that other driver maintainers can get up to speed with it.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
