libcxgb: Don't accidentally set RTO_ONLINK in cxgb_find_route()

2022-01-12T04:36:08Z

Mask the ECN bits before calling ip_route_output_ports(). The tos variable might be passed directly from an IPv4 header, so it may have the last ECN bit set. This interferes with the route lookup process as ip_route_output_key_hash() interpretes this bit specially (to restrict the route scope). Found by code inspection, compile tested only.

chelsio: Replace zero-length array with flexible-array member

2020-02-24T23:26:17Z

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

treewide: prefix header search paths with $(srctree)/

2019-05-18T02:49:57Z

Currently, the Kbuild core manipulates header search paths in a crazy way [1]. To fix this mess, I want all Makefiles to add explicit $(srctree)/ to the search paths in the srctree. Some Makefiles are already written in that way, but not all. The goal of this work is to make the notation consistent, and finally get rid of the gross hacks. Having whitespaces after -I does not matter since commit 48f6e3cf5bc6 ("kbuild: do not drop -I without parameter"). [1]: https://patchwork.kernel.org/patch/9632347/ Signed-off-by: Masahiro Yamada

libcxgb: fix incorrect ppmax calculation

2019-04-05T00:40:26Z

BITS_TO_LONGS() uses DIV_ROUND_UP() because of this ppmax value can be greater than available per cpu page pods. This patch removes BITS_TO_LONGS() to fix this issue. Signed-off-by: Varun Prakash Signed-off-by: David S. Miller

networking: make skb_put & friends return void pointers

2017-06-16T15:48:39Z

It seems like a historic accident that these return unsigned char *, and in many places that means casts are required, more often than not. Make these functions (skb_put, __skb_put and pskb_put) return void * and remove all the casts across the tree, adding a (u8 *) cast only where the unsigned char pointer was used directly, all done with the following spatch: @@ expression SKB, LEN; typedef u8; identifier fn = { skb_put, __skb_put }; @@ - *(fn(SKB, LEN)) + *(u8 *)fn(SKB, LEN) @@ expression E, SKB, LEN; identifier fn = { skb_put, __skb_put }; type T; @@ - E = ((T *)(fn(SKB, LEN))) + E = fn(SKB, LEN) which actually doesn't cover pskb_put since there are only three users overall. A handful of stragglers were converted manually, notably a macro in drivers/isdn/i4l/isdn_bsdcomp.c and, oddly enough, one of the many instances in net/bluetooth/hci_sock.c. In the former file, I also had to fix one whitespace problem spatch introduced. Signed-off-by: Johannes Berg Signed-off-by: David S. Miller
