net: introduce SO_BPF_EXTENSIONS

2014-01-19T03:08:58Z

For user space packet capturing libraries such as libpcap, there's currently only one way to check which BPF extensions are supported by the kernel, that is, commit aa1113d9f85d ("net: filter: return -EINVAL if BPF_S_ANC* operation is not supported"). For querying all extensions at once this might be rather inconvenient. Therefore, this patch introduces a new option which can be used as an argument for getsockopt(), and allows one to obtain information about which BPF extensions are supported by the current kernel. As David Miller suggests, we do not need to define any bits right now and status quo can just return 0 in order to state that this versions supports SKF_AD_PROTOCOL up to SKF_AD_PAY_OFFSET. Later additions to BPF extensions need to add their bits to the bpf_tell_extensions() function, as documented in the comment.

net: introduce SO_MAX_PACING_RATE

2013-09-28T22:35:41Z

As mentioned in commit afe4fd062416b ("pkt_sched: fq: Fair Queue packet scheduler"), this patch adds a new socket option. SO_MAX_PACING_RATE offers the application the ability to cap the rate computed by transport layer. Value is in bytes per second. u32 val = 1000000; setsockopt(sockfd, SOL_SOCKET, SO_MAX_PACING_RATE, &val, sizeof(val)); To be effectively paced, a flow must use FQ packet scheduler. Note that a packet scheduler takes into account the headers for its computations. The effective payload rate depends on MSS and retransmits if any. I chose to make this pacing rate a SOL_SOCKET option instead of a TCP one because this can be used by other protocols. Signed-off-by: Eric Dumazet Cc: Steinar H.

net: rename busy poll socket op and globals

Rename LL_SO to BUSY_POLL_SO Rename sysctl_net_ll_{read,poll} to sysctl_busy_{read,poll} Fix up users of these variables.

net: add socket option for low latency polling

net: add option to enable error queue packets waking select

2013-03-31T23:44:20Z

Currently, when a socket receives something on the error queue it only wakes up the socket on select if it is in the "read" list, that is the socket has something to read. It is useful also to wake the socket if it is in the error list, which would enable software to wait on error queue packets without waking up for regular data on the socket. The main use case is for receiving timestamped transmit packets which return the timestamp to the socket via the error queue. This enables an application to select on the socket for the error queue only instead of for the regular traffic. -v2- * Added the SO_SELECT_ERR_QUEUE socket option to every architechture specific file * Modified every socket poll function that checks error queue Signed-off-by: Jacob Keller Cc: Jeffrey Kirsher Cc: Richard Cochran Cc: Matthew Vick Signed-off-by: David S.

cris: use "int" for ssize_t to match size_t

2013-02-22T01:22:16Z

On cris-linux-gcc, __SIZE_TYPE__ expands to "unsigned int", as gcc-4.6.3-nolibc/cris-linux/lib/gcc/cris-linux/4.6.3/plugin/include/config/cris/linux.h has #define SIZE_TYPE "unsigned int" Hence __kernel_size_t is also "unsigned int". But __kernel_ssize_t is "long", which has a different base type, causing compiler warnings like: fs/quota/quota_tree.c:372:4: warning: format '%zd' expects argument of type 'signed size_t', but argument 4 has type 'ssize_t' [-Wformat] To fix this, __kernel_ssize_t should be changed to "int". Hence cris can just use the generic 32-bit versions from include/asm-generic/posix_types.h for all size-related types.
