 1.48  05-Jul-2024  rin sys: Drop redundant NULL check before m_freem(9)

m_freem(9) safely has accepted NULL argument at least since 4.2BSD:
https://www.tuhs.org/cgi-bin/utree.pl?file=4.2BSD/usr/src/sys/sys/uipc_mbuf.c

Compile-tested on amd64/ALL.

Patch posted to tech-net@
http://mail-index.netbsd.org/tech-net/2015/03/15/msg005004.html

The choice to use a new structure sockaddr_big has been retained since
changing sockaddr_storage size would lead to unnecessary ABI change. The
use of the new structure does not preclude future work that increases
the size of sockaddr_storage and at that time sockaddr_big may be
trivially replaced.

- replace calls to pr_generic() with req = PRU_CONNECT2 with calls to
pr_connect2()

- replace calls to pr_generic() with req = PRU_PURGEIF with calls to
pr_purgeif()

put common code from unp_connect2() (used by unp_connect() into
unp_connect1() and call out to it when needed

welcome to netbsd 6.99.48
 1.33  23-Jul-2014  rtr split PRU_SENDOOB and PRU_RCVOOB function out of pr_generic() usrreq
switches and put into separate functions
xxx_sendoob(struct socket *, struct mbuf *, struct mbuf *)
xxx_recvoob(struct socket *, struct mbuf *, int)

- always KASSERT(solocked(so)) even if request is not implemented

- replace calls to pr_generic() with req = PRU_{SEND,RCV}OOB with
calls to pr_{send,recv}oob() respectively.

there is still some tweaking of m_freem(m) and m_freem(control) to come
for consistency. not performed with this commit for clarity.

reviewed by rmind
 1.32  09-Jul-2014  rtr * split PRU_ACCEPT function out of pr_generic() usrreq switches and put
into a separate function xxx_accept(struct socket *, struct mbuf *)

note: future cleanup will take place to remove struct mbuf parameter
type and replace it with a more appropriate type.

patch reviewed by rmind
 1.31  09-Jul-2014  rtr * split PRU_PEERADDR and PRU_SOCKADDR function out of pr_generic()
usrreq switches and put into separate functions
xxx_{peer,sock}addr(struct socket *, struct mbuf *).

- KASSERT(solocked(so)) always in new functions even if request
is not implemented

- KASSERT(pcb != NULL) and KASSERT(nam) if the request is
implemented and not for tcp.

* for tcp roll #ifdef KPROF and #ifdef DEBUG code from tcp_usrreq() into
easier to cut & paste functions tcp_debug_capture() and
tcp_debug_trace()

- functions provided by rmind
- remaining use of PRU_{PEER,SOCK}ADDR #define to be removed in a
future commit.

* rename netbt functions to permit consistency of pru function names
(as has been done with other requests already split out).

- l2cap_{peer,sock}addr() -> l2cap_{peer,sock}_addr_pcb()
- rfcomm_{peer,sock}addr() -> rfcomm_{peer,sock}_addr_pcb()
- sco_{peer,sock}addr() -> sco_{peer,sock}_addr_pcb()

* split/refactor do_sys_getsockname(lwp, fd, which, nam) into
two functions do_sys_get{peer,sock}name(fd, nam).

- move PRU_PEERADDR handling into do_sys_getpeername() from
do_sys_getsockname()
- have svr4_stream directly call do_sys_get{sock,peer}name()
respectively instead of providing `which' & fix a DPRINTF string
that incorrectly wrote "getpeername" when it meant "getsockname"
- fix sys_getpeername() and sys_getsockname() to call
do_sys_get{sock,peer}name() without `which' and `lwp' & adjust
comments
- bump kernel version for removal of lwp & which parameters from
do_sys_getsockname()

note: future cleanup to remove struct mbuf * abuse in
xxx_{peer,sock}name()
still to come, not done in this commit since it is easier to do post
split.

welcome to 6.99.47
 1.30  07-Jul-2014  rtr * sprinkle KASSERT(solocked(so)); in all pr_stat() functions.
* fix remaining inconsistent struct socket parameter names.
 1.29  07-Jul-2014  rtr backout change that made pr_stat return EOPNOTSUPP for protocols that
were not filling in struct stat.

decision made after further discussion with rmind and investigation of
how other operating systems behave. soo_stat() is doing just enough to
be able to call what gets returned valid and thus justifys a return of
success.

additional review will be done to determine of the pr_stat functions
that were already returning EOPNOTSUPP can be considered successful with
what soo_stat() is doing.
 1.28  07-Jul-2014  rtr * have pr_stat return EOPNOTSUPP consistently for all protocols that do
not fill in struct stat instead of returning success.

* in pr_stat remove all checks for non-NULL so->so_pcb except where the
pcb is actually used (i.e. cases where we don't return EOPNOTSUPP).

proposed on tech-net@
 1.27  06-Jul-2014  rtr * split PRU_SENSE functionality out of xxx_usrreq() switches and place into
separate xxx_stat(struct socket *, struct stat *) functions.
* replace calls using pr_generic with req == PRU_SENSE with pr_stat().

further change will follow that cleans up the pattern used to extract the
pcb and test for its presence.

reviewed by rmind
 1.26  01-Jul-2014  rtr fix parameter types in pr_ioctl, called xx_control() functions and remove
abuse of pointer to struct mbuf type.

param2 changed to u_long type and uses parameter name 'cmd' (ioctl command)
param3 changed to void * type and uses parameter name 'data'
param4 changed to struct ifnet * and uses parameter name 'ifp'
param5 has been removed (formerly struct lwp *) and uses of 'l' have been
replaced with curlwp from curproc(9).

callers have had (now unnecessary) casts to struct mbuf * removed, called
code has had (now unnecessary) casts to u_long, void * and struct ifnet *
respectively removed.

reviewed by rmind@
 1.25  22-Jun-2014  rtr * split PRU_CONTROL functionality out of xxx_userreq() switches and place
into separate xxx_ioctl() functions.
* place KASSERT(req != PRU_CONTROL) inside xxx_userreq() as it is now
inappropriate for req = PRU_CONTROL in xxx_userreq().
* replace calls to pr_generic() with req = PRU_CONTROL with pr_ioctl().
* remove & fixup references to PRU_CONTROL xxx_userreq() function comments.
* fix various comments references for xxx_userreq() that mentioned
PRU_CONTROL as xxx_userreq() no longer handles the request.

a further change will follow to fix parameter and naming inconsistencies
retained from original code.
