[NET]: Make skb->protocol __be16

2005-08-11T23:05:50Z

There are many instances of skb->protocol = htons(ETH_P_*); skb->protocol = __constant_htons(ETH_P_*); and skb->protocol = *_type_trans(...); Most of *_type_trans() are already endian-annotated, so, let's shift attention on other warnings.

[NET]: Reduce size of sk_buff by 4 bytes

2005-07-05T21:13:41Z

Reduce local_df to a bit field and ip_summed to a 2 bits field thus saving 13 bits. Move bit fields, packet type, and protocol into the spare area between the priority and the destructor. Saves 4 bytes on both, 32bit and 64bit architectures. Signed-off-by: Thomas Graf Signed-off-by: David S. Miller

[NET]: Fix signedness issues in net/core/filter.c

2005-07-05T21:08:10Z

This is the code to load packet data into a register: k = fentry->k; if (k < 0) { ... } else { u32 _tmp, *p; p = skb_header_pointer(skb, k, 4, &_tmp); if (p != NULL) { A = ntohl(*p); continue; } } skb_header_pointer checks if the requested data is within the linear area: int hlen = skb_headlen(skb); if (offset + len <= hlen) return skb->data + offset; When offset is within [INT_MAX-len+1..INT_MAX] the addition will result in a negative number which is <= hlen. I couldn't trigger a crash on my AMD64 with 2GB of memory, but a coworker tried on his x86 machine and it crashed immediately. This patch fixes the check in skb_header_pointer to handle large positive offsets similar to skb_copy_bits. Invalid data can still be accessed using negative offsets (also similar to skb_copy_bits), anyone using negative offsets needs to verify them himself. Thanks to Thomas V�gtle for verifying the problem by crashing his machine and providing me with an Oops. Signed-off-by: Patrick McHardy Acked-by: Herbert Xu Signed-off-by: David S. Miller

[NET]: skb_find_text() - Find a text pattern in skb data

2005-06-24T04:00:17Z

Finds a pattern in the skb data according to the specified textsearch configuration. Use textsearch_next() to retrieve subsequent occurrences of the pattern. Returns the offset to the first occurrence or UINT_MAX if no match was found. Signed-off-by: Thomas Graf Signed-off-by: David S. Miller

[NET]: Zerocopy sequential reading of skb data

2005-06-24T03:59:51Z

Implements sequential reading for both linear and non-linear skb data at zerocopy cost. The data is returned in chunks of arbitary length, therefore random access is not possible. Usage: from := 0 to := 128 state := undef data := undef len := undef consumed := 0 skb_prepare_seq_read(skb, from, to, &state) while (len = skb_seq_read(consumed, &data, &state)) != 0 do /* do something with 'data' of length 'len' */ if abort then /* abort read if we don't wait for * skb_seq_read() to return 0 */ skb_abort_seq_read(&state) return endif /* not necessary to consume all of 'len' */ consumed += len done Signed-off-by: Thomas Graf Signed-off-by: David S.
