[PPP] generic: Fix receive path data clobbering & non-linear handling

2007-09-16T23:22:13+00:00

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.

[PPP] generic: Call skb_cow_head before scribbling over skb

2007-09-16T23:21:42+00:00

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.

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

2007-08-22T03:59:35+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.

unregister_chrdev(): ignore the return value

2007-07-19T17:04:43+00:00

unregister_chrdev() always returns 0.  There is no need to check the return
value.

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

2007-06-24T06:05:54+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.

header cleaning: don't include smp_lock.h when not used

2007-05-08T18:15:07+00:00

Remove includes of  where it is not used/needed.
Suggested by Al Viro.

Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc,
sparc64, and arm (all 59 defconfigs).

[SK_BUFF]: Introduce skb_reset_mac_header(skb)

2007-04-26T05:24:32+00:00

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.

This one touches just the most simple case, next will handle the slightly more
"complex" cases.

[PATCH] mark struct file_operations const 5

2007-02-12T17:48:45+00:00

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.
