.SH DESCRIPTION
|
|
|
|
The sock_diag netlink subsystem provides a mechanism for obtaining
|
2016-12-07 14:40:29 +00:00
|
|
|
information about sockets of various address families from the kernel.
|
2016-12-07 13:59:43 +00:00
|
|
|
This subsystem can be used to obtain information about individual
|
|
|
|
sockets or request a list of sockets.
|
2017-08-12 20:41:59 +00:00
|
|
|
.PP
|
2016-12-07 14:40:29 +00:00
|
|
|
In the request, the caller can specify additional information it would
|
|
|
|
like to obtain about the socket, for example, memory information or
|
|
|
|
information specific to the address family.
|
2017-08-12 20:41:59 +00:00
|
|
|
.PP
|
2016-12-07 13:59:43 +00:00
|
|
|
When requesting a list of sockets, the caller can specify filters that
|
|
|
|
would be applied by the kernel to select a subset of sockets to report.
|
2016-12-07 14:40:29 +00:00
|
|
|
For now, there is only the ability to filter sockets by state (connected,
|
|
|
|
listening, and so on.)
|
2017-08-12 20:41:59 +00:00
|
|
|
.PP
|
2016-12-07 14:40:29 +00:00
|
|
|
Note that sock_diag reports only those sockets that have a name;
|
|
|
|
that is, either sockets bound explicitly with
|
2016-12-07 13:59:43 +00:00
|
|
|
.BR bind (2)
|
|
|
|
or sockets that were automatically bound to an address (e.g., by
|
|
|
|
.BR connect (2)).
|
|
|
|
This is the same set of sockets that is available via
|
|
|
|
.IR /proc/net/unix ,
|
|
|
|
.IR /proc/net/tcp ,
|
|
|
|
.IR /proc/net/udp ,
|
2016-12-07 14:40:29 +00:00
|
|
|
and so on.

Quoting Branden:
*roff escape sequences may sometimes look like C escapes, but that
is misleading. *roff is in part a macro language and that means
recursive expansion to arbitrary depths.
You can get away with "\\" in a context where no macro expansion
is taking place, but try to spell a literal backslash this way in
the argument to a macro and you will likely be unhappy with
results.
Try viewing the attached file with "man -l".
"\e" is the preferred and portable way to get a portable "escape
literal" going back to CSTR #54, the original Bell Labs troff
paper.
groff(7) discusses the issue:
\\ reduces to a single backslash; useful to delay its
interpretation as escape character in copy mode. For a
printable backslash, use \e, or even better \[rs], to be
independent from the current escape character.
As of groff 1.22.4, groff_man(7) does as well:
\e Widely used in man pages to represent a backslash output
glyph. It works reliably as long as the .ec request is
not used, which should never happen in man pages, and it
is slightly more portable than the more exact ‘\(rs’
(“reverse solidus”) escape sequence.
People not concerned with portability to extremely old troffs should
probably just use \(rs (or \[rs]), as it means "the backslash
glyph", not "the glyph corresponding to whatever the current escape
character is".

literal" going back to CSTR #54, the original Bell Labs troff
paper.
groff(7) discusses the issue:
\\ reduces to a single backslash; useful to delay its
interpretation as escape character in copy mode. For a
printable backslash, use \e, or even better \[rs], to be
independent from the current escape character.
As of groff 1.22.4, groff_man(7) does as well:
\e Widely used in man pages to represent a backslash output
glyph. It works reliably as long as the .ec request is
not used, which should never happen in man pages, and it
is slightly more portable than the more exact ‘\(rs’
(“reverse solidus”) escape sequence.
People not concerned with portability to extremely old troffs should
probably just use \(rs (or \[rs]), as it means "the backslash
glyph", not "the glyph corresponding to whatever the current escape
character is".

Quoting Branden:
*roff escape sequences may sometimes look like C escapes, but that
is misleading. *roff is in part a macro language and that means
recursive expansion to arbitrary depths.
You can get away with "\\" in a context where no macro expansion
is taking place, but try to spell a literal backslash this way in
the argument to a macro and you will likely be unhappy with
results.
Try viewing the attached file with "man -l".
"\e" is the preferred and portable way to get a portable "escape
literal" going back to CSTR #54, the original Bell Labs troff
paper.
groff(7) discusses the issue:
\\ reduces to a single backslash; useful to delay its
interpretation as escape character in copy mode. For a
printable backslash, use \e, or even better \[rs], to be
independent from the current escape character.
As of groff 1.22.4, groff_man(7) does as well:
\e Widely used in man pages to represent a backslash output
glyph. It works reliably as long as the .ec request is
not used, which should never happen in man pages, and it
is slightly more portable than the more exact ‘\(rs’
(“reverse solidus”) escape sequence.
People not concerned with portability to extremely old troffs should
probably just use \(rs (or \[rs]), as it means "the backslash
glyph", not "the glyph corresponding to whatever the current escape
character is".
