2007-10-17[UMP]: header_ops conversion needed for non-ethernet driversJeff Dike
UML's two non-ethernet drivers need some header_ops conversion. Signed-off-by: Jeff Dike <jdike@linux.intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-16uml: network driver MTU cleanupsJeff Dike
A bunch of MTU-related cleanups in the network code. First, there is the addition of the notion of a maximally-sized packet, which is the MTU plus headers. This is used to size the skb that will receive a packet. This allows ether_adjust_skb to go away, as it was used to resize the skb after it was allocated. Since the skb passed into the low-level read routine is no longer resized, and possibly reallocated, there, they (and the write routines) don't need to get an sk_buff **. They just need the sk_buff * now. The callers of ether_adjust_skb still need to do the skb_put, so that's now inlined. The MAX_PACKET definitions in most of the drivers are gone. The set_mtu methods were all the same and did nothing, so they can be removed. The ethertap driver had a typo which doubled the size of the packet rather than adding two bytes to it. It also wasn't defining its setup_size, causing a zero-byte kmalloc and crash when the invalid pointer returned from kmalloc was dereferenced.

2007-10-16uml: network formattingJeff Dike
Style and other non-functional changes in the UML networking code, including include tidying style violations copyright updates printks getting severities userspace code calling libc directly rather than using the os_* wrappers There's also a exit path cleanup in the pcap driver.

2007-04-25[SK_BUFF]: Introduce skb_mac_header()Arnaldo Carvalho de Melo
For the places where we need a pointer to the mac header, it is still legal to touch skb->mac.raw directly if just adding to, subtracting from or setting it to another layer header. This one also converts some more cases to skb_reset_mac_header() that my regex missed as it had no spaces before nor after '=', ugh.

2006-12-07[PATCH] uml: use get_random_bytes() after random pool is seededJeff Dike
When the UML network driver generates random MACs for its devices, it was possible for a number of UMLs to get the same MACs because the ethernet initialization was done before the random pool was properly seeded. This patch moves the initialization later so that it gets better randomness.

2006-09-27[PATCH] uml: const more dataJeff Dike
Make lots of structures const in order to make it obvious that they need no locking. Signed-off-by: Jeff Dike <jdike@addtoit.com> Cc: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

A number of UML initcalls were improperly returning 1. Also removed any nearby emacs formatting comments.

2006-02-01[PATCH] uml: fix hugest stack usersPaolo 'Blaisorblade' Giarrusso
The C99 initialization, with GCC's bad handling, for 6K wide structs (which _aren't_ on the stack), is causing GCC to use 12K for these silly procs with 3 vars. Workaround this. Note that .name = { '\0' } translates to memset(->name, 0, '->name' size) - I verified this with GCC's docs and a testprogram.

2005-06-13[PATCH] uml: slirp and slip driver cleanups and fixesJeff Dike
This patch merges a lot of duplicated code in the slip and slirp drivers, abstracts out the slip protocol, and makes the slip driver work in 2.6. Signed-off-by: Jeff Dike <jdike@addtoit.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
