2007-09-16[PPP] generic: Fix receive path data clobbering & non-linear handlingHerbert Xu
This patch adds missing pskb_may_pull calls to deal with non-linear packets that may arrive from pppoe or pppol2tp. It also copies cloned packets before writing over them. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

It's rude to write over data that other people are still using. So call skb_cow_head before PPP proceeds to modify the skb data. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-08-21[PPP]: Fix output buffer size in ppp_decompress_frame().Konstantin Sharlaimov
This patch addresses the issue with "osize too small" errors in mppe encryption. The patch fixes the issue with wrong output buffer size being passed to ppp decompression routine. -------------------- As pointed out by Suresh Mahalingam, the issue addressed by ppp-fix-osize-too-small-errors-when-decoding patch is not fully resolved yet. The size of allocated output buffer is correct, however it size passed to ppp->rcomp->decompress in ppp_generic.c if wrong. The patch fixes that. -------------------- Signed-off-by: Konstantin Sharlaimov <konstantin.sharlaimov@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-04-25[SK_BUFF]: Introduce skb_reset_mac_header(skb)Arnaldo Carvalho de Melo
For the common, open coded 'skb->mac.raw = skb->data' operation, so that we can later turn skb->mac.raw into a offset, reducing the size of struct sk_buff in 64bit land while possibly keeping it as a pointer on 32bit.

2006-06-17[NET] ppp: Remove unnecessary pskb_may_pullHerbert Xu
In ppp_receive_nonmp_frame, we call pskb_may_pull(skb, skb->len) if the tailroom is >= 124. This is pointless because this pskb_may_pull is only needed if the skb is non-linear. However, if it is non-linear then the tailroom would be zero. So it can be safely removed. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

2006-03-20[NET]: Replace skb_pull/skb_postpull_rcsum with skb_pull_rcsumHerbert Xu
We're now starting to have quite a number of places that do skb_pull followed immediately by an skb_postpull_rcsum. We can merge these two operations into one function with skb_pull_rcsum. This makes sense since most pull operations on receive skb's need to update the checksum. I've decided to make this out-of-line since it is fairly big and the fast path where hardware checksums are enabled need to call csum_partial anyway. Since this is a brand new function we get to add an extra check on the len argument. As it is most callers of skb_pull ignore its return value which essentially means that there is no check on the len argument.

2006-02-05[PPP]: Fixed hardware RX checksum handlingHerbert Xu
When we pull the PPP protocol off the skb, we forgot to update the hardware RX checksum. This may lead to messages such as dsl0: hw csum failure. Similarly, we need to clear the hardware checksum flag when we use the existing packet to store the decompressed result.

2005-12-27[NET]: Validate socket filters against BPF_MAXINSNS in one spot.David S. Miller

2005-11-08[PPP]: add PPP MPPE encryption moduleMatt Domsch
From: Matt Domsch <Matt_Domsch@dell.com> The patch below implements the Microsoft Point-to-Point Encryption method as a PPP compressor/decompressor. This is necessary for Linux clients and servers to interoperate with Microsoft Point-to-Point Tunneling Protocol (PPTP) servers (either Microsoft PPTP servers or the poptop project) which use MPPE to encrypt data when creating a VPN. This patch differs from the kernel_ppp_mppe DKMS pacakge at pptpclient.sourceforge.net by utilizing the kernel crypto routines rather than providing its own SHA1 and arcfour implementations. Minor changes to ppp_generic.c try to prevent a link from disabling compression (in our case, the encryption) after it has started using compression (encryption).

2005-07-08[NET]: Transform skb_queue_len() binary tests into skb_queue_empty()David S. Miller
This is part of the grand scheme to eliminate the qlen member of skb_queue_head, and subsequently remove the 'list' member of sk_buff. Most users of skb_queue_len() want to know if the queue is empty or not, and that's trivially done with skb_queue_empty() which doesn't use the skb_queue_head->qlen member and instead uses the queue list emptyness as the test.

2005-05-12 [PATCH] PPP multilink fragmentation improvementsPaul Mackerras
Here's a patch for -mm for now. Not sure whose territory this falls in, so I'm sending it to everyone I can think of. :) Some time ago I did some experiments with using PPP multilink over largish numbers of channels (up to 32). The TCP performance was woeful due to wildly fluctuating packet latencies, which turned out to be because we would sometimes split a packet across all 32 channels, and sometimes we would send a whole packet down a single channel. This patch fixes those problems by being a bit cleverer about how the packets are split across the available channels, and in particular, it waits until at least half of the channels can take another fragment before starting to split up the next packet. The patch also fixes a buglet in the multilink reconstruction code where it would discard incoming packets that had just the multilink header and no data. Such packets are valid and shouldn't be discarded. Signed-off-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

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!
