ipv6: Add IPv6 multicast address flag defines

2011-02-22T18:07:27+00:00

This commit adds the missing IPv6 multicast address flag defines to complement the already existing multicast address scope defines and to be able to check these flags nicely in the future. Signed-off-by: Linus Lüssing Signed-off-by: David S. Miller

net: return operator cleanup

2010-09-23T21:33:39+00:00

Change "return (EXPR);" to "return EXPR;" return is not a function, parentheses are not required. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

snmp: 64bit ipstats_mib for all arches

2010-06-30T20:31:19+00:00

/proc/net/snmp and /proc/net/netstat expose SNMP counters. Width of these counters is either 32 or 64 bits, depending on the size of "unsigned long" in kernel. This means user program parsing these files must already be prepared to deal with 64bit values, regardless of user program being 32 or 64 bit. This patch introduces 64bit snmp values for IPSTAT mib, where some counters can wrap pretty fast if they are 32bit wide. # netstat -s|egrep "InOctets|OutOctets" InOctets: 244068329096 OutOctets: 244069348848 Signed-off-by: Eric Dumazet Signed-off-by: David S.

ipv6: Refactor update of IPv6 flowi destination address for srcrt (RH) option

2010-06-02T14:08:31+00:00

There are more than a dozen occurrences of following code in the IPv6 stack: if (opt && opt->srcrt) { struct rt0_hdr *rt0 = (struct rt0_hdr *) opt->srcrt; ipv6_addr_copy(&final, &fl.fl6_dst); ipv6_addr_copy(&fl.fl6_dst, rt0->addr); final_p = &final; } Replace those with a helper. Note that the helper overrides final_p in all cases. This is ok as final_p was previously initialized to NULL when declared. Signed-off-by: Arnaud Ebalard Signed-off-by: David S. Miller

kernel-wide: replace USHORT_MAX, SHORT_MAX and SHORT_MIN with USHRT_MAX, SHRT_MAX and SHRT_MIN

2010-05-25T15:07:02+00:00

- C99 knows about USHRT_MAX/SHRT_MAX/SHRT_MIN, not USHORT_MAX/SHORT_MAX/SHORT_MIN. - Make SHRT_MIN of type s16, not int, for consistency.

IPv6: Complete IPV6_DONTFRAG support

2010-04-24T06:35:29+00:00

Finally add support to detect a local IPV6_DONTFRAG event and return the relevant data to the user if they've enabled IPV6_RECVPATHMTU on the socket. The next recvmsg() will return no data, but have an IPV6_PATHMTU as ancillary data. Signed-off-by: Brian Haley Signed-off-by: David S. Miller

IPv6: Add dontfrag argument to relevant functions

2010-04-24T06:35:28+00:00

Add dontfrag argument to relevant functions for IPV6_DONTFRAG support, as well as allowing the value to be passed-in via ancillary cmsg data. Signed-off-by: Brian Haley Signed-off-by: David S. Miller

net: replace ipfragok with skb->local_df

2010-04-16T06:36:37+00:00

As Herbert Xu said: we should be able to simply replace ipfragok with skb->local_df. commit f88037(sctp: Drop ipfargok in sctp_xmit function) has droped ipfragok and set local_df value properly. The patch kills the ipfragok parameter of .queue_xmit(). Signed-off-by: Shan Wei Signed-off-by: David S. Miller

ipv6: Use fls() instead of fls() in ipv6_addr_diff().

2010-03-31T06:28:46+00:00

Because we have ensured that the argument is non-zero, it is better to use __fls() and generate better code. Signed-off-by: YOSHIFUJI Hideaki Signed-off-by: David S. Miller

ipv6: Remove IPV6_ADDR_RESERVED

2010-02-26T11:59:07+00:00

RFC 4291 section 2.4 states that all uncategorized addresses should be considered as Global Unicast. This will remove IPV6_ADDR_RESERVED completely and return IPV6_ADDR_UNICAST in ipv6_addr_type() instead. Signed-off-by: Ulrich Weber Signed-off-by: David S. Miller
