[PPP]: Fix output buffer size in ppp_decompress_frame().

2007-09-24T21:02:46+00:00

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 Signed-off-by: David S. Miller Signed-off-by: Adrian Bunk

[PPP]: Fix osize too small errors when decoding mppe.

2007-09-24T21:01:54+00:00

The mppe_decompress() function required a buffer that is 1 byte too small when receiving a message of mru size. This fixes buffer allocation to prevent this from occurring. Signed-off-by: Konstantin Sharlaimov Signed-off-by: David S. Miller Signed-off-by: Adrian Bunk

[PPP]: Fixed hardware RX checksum handling

2006-02-06T04:23:33+00:00

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. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller

[NET]: Validate socket filters against BPF_MAXINSNS in one spot.

2005-12-27T21:57:59+00:00

Currently the checks are scattered all over and this leads to inconsistencies and even cases where the check is not made. Based upon a patch from Kris Katterjohn. Signed-off-by: David S. Miller

[PPP]: add PPP MPPE encryption module

2005-11-08T17:40:47+00:00

From: Matt Domsch 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). Feedback to please.

[PATCH] Driver Core: fix up all callers of class_device_create()

2005-10-28T16:52:52+00:00

The previous patch adding the ability to nest struct class_device changed the paramaters to the call class_device_create(). This patch fixes up all in-kernel users of the function. Signed-off-by: Greg Kroah-Hartman

[NET]: Remove explicit initializations of skb->input_dev

2005-08-29T22:33:26+00:00

Instead, set it in one place, namely the beginning of netif_receive_skb(). Based upon suggestions from Jamal Hadi Salim. Signed-off-by: David S. Miller

[NET]: Transform skb_queue_len() binary tests into skb_queue_empty()

2005-07-08T21:57:23+00:00

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.
