usage of NIP6
commit cf4ca4874fc45 removed the definition of NIPQUAD and NIPQUAD_FMT,
and NIP6 also is out of date.
commit 2874762b31d8d replace deprecated NIPQUAD marco to C code, but we can use %pI4 to
print IPv4 address more simply. And remove constant condition judge.
Because DEBUG_SDU is not defined in gdm_wimax.h, no error message when compiling.

The calculation of RTTVAR involves the subtraction of two unsigned

may causes rollover and results in very high values of RTTVAR when RTT > SRTT.
With this patch it is possible to set RTOmin = 1 to get the minimum of RTO at
4 times the clock granularity.

Consider the following program, that sets the second argument to the
sendto() syscall incorrectly:
#include <string.h>
#include <arpa/inet.h>
#include <sys/socket.h>
int main(void)
{
int fd;
struct sockaddr_in sa;
fd = socket(AF_INET, SOCK_STREAM, 132 /*IPPROTO_SCTP*/);
if (fd < 0)
return 1;
memset(&sa, 0, sizeof(sa));
sa.sin_family = AF_INET;
sa.sin_addr.s_addr = inet_addr("127.0.0.1");
sa.sin_port = htons(11111);
sendto(fd, NULL, 1, 0, (struct sockaddr *)&sa, sizeof(sa));
return 0;
}
We get -ENOMEM:
$ strace -e sendto ./demo
sendto(3, NULL, 1, 0, {sa_family=AF_INET, sin_port=htons(11111), sin_addr=inet_addr("127.0.0.1")}, 16) = -1 ENOMEM (Cannot allocate memory)
Propagate the error code from sctp_user_addto_chunk(), so that we will
tell user space what actually went wrong:
$ strace -e sendto ./demo
sendto(3, NULL, 1, 0, {sa_family=AF_INET, sin_port=htons(11111), sin_addr=inet_addr("127.0.0.1")}, 16) = -1 EFAULT (Bad address)
Noticed while running Trinity (the syscall fuzzer).

fails
Trinity (the syscall fuzzer) discovered a memory leak in SCTP,
reproducible e.g. with the sendto() syscall by passing invalid
user space pointer in the second argument:
#include <string.h>
#include <arpa/inet.h>
#include <sys/socket.h>
int main(void)
{
int fd;
struct sockaddr_in sa;
fd = socket(AF_INET, SOCK_STREAM, 132 /*IPPROTO_SCTP*/);
if (fd < 0)
return 1;
memset(&sa, 0, sizeof(sa));
sa.sin_family = AF_INET;
sa.sin_addr.s_addr = inet_addr("127.0.0.1");
sa.sin_port = htons(11111);
sendto(fd, NULL, 1, 0, (struct sockaddr *)&sa, sizeof(sa));
return 0;
}
As far as I can tell, the leak has been around since ~2003.

task_cputime_adjusted() and thread_group_cputime_adjusted()
essentially share the same code. They just don't use the same
source:
* The first function uses the cputime in the task struct and the
previous adjusted snapshot that ensures monotonicity.
* The second adds the cputime of all tasks in the group and the
previous adjusted snapshot of the whole group from the signal
structure.
Just consolidate the common code that does the adjustment. These
functions just need to fetch the values from the appropriate
source.

We have thread_group_cputime() and thread_group_times(). The naming
doesn't provide enough information about the difference between
these two APIs.
To lower the confusion, rename thread_group_times() to
thread_group_cputime_adjusted(). This name better suggests that
it's a version of thread_group_cputime() that does some stabilization
on the raw cputime values. ie here: scale on top of CFS runtime
stats and bound lower value for monotonicity.

Having the functional unit names in each bank decode is only misleading
as this code supports multiple families and there's no guarantee the
mapping between FUs and MCE banks will stay the same.
And also, knowing the functional unit name doesn't help much since you
end up looking at the respective BKDG anyway.
So drop all FU references and use the MC bank numbers instead.
