* net.c (print_linger): Rename to print_set_linger.
(print_setsockopt): Replace print_linger with print_set_linger.
(print_get_linger): New function that accepts arbitrary option length
to match the kernel behaviour.
(print_getsockopt): Replace print_linger with print_get_linger.
* NEWS: Mention this.
As the last argument of getsockopt syscall has read-write semantics,
print both user and kernel values when they differ.
* net.c (SYS_FUNC(getsockopt)): On entering syscall, fetch and save
the length specified to the kernel. On error, print the length saved
on entering. When the saved length and the length returned by the
kernel differ, print both values.
* NEWS: Mention this.
* tests/net-icmp_filter.c (main): Update expected output.
The side effect of #include "xlat/netlink_protocols.h" is
NETLINK_* constants properly defined in that header file.
While net.c does not use these constants itself, netlink.c
is going to need them soon.
* net.c: Move inclusion of "xlat/netlink_protocols.h" ...
* netlink.c: ... here.
Remove temporary macros created for transition from long
to kernel_ulong_t.
Automatically replace PRI_kr[dux] with PRI_kl[dux] using
$ git grep -l 'PRI_kr[dux]' | xargs sed -ri 's/PRI_kr([dux])/PRI_kl\1/g'
* defs.h (PRI_krd, PRI_kru, PRI_krx): Remove. All users updated.
Remove temporary types created for transition from long
to kernel_ulong_t.
Automatically replace kernel_scno_t and kernel_ureg_t with
kernel_ulong_t using
$ git grep -El 'kernel_(scno|ureg)_t' |
xargs sed -ri 's/kernel_(scno|ureg)_t/kernel_ulong_t/g'
* kernel_types.h (kernel_scno_t, kernel_ureg_t): Remove.
All users updated.
Prepare for the change of kernel_ureg_t and kernel_scno_t from
unsigned long to kernel_ulong_t.
* defs.h (PRI_krd, PRI_kru, PRI_krx): New temporary macros.
All users updated.
As about half of all printstr uses cases are invocations with the last
argument set to -1, create a dedicated function for this use case.
* defs.h (printstr): Rename to printstrn. All callers updated.
(printstr): New static inline function. All callers updated.
As new constants have been added gradually over kernel releases, define
all constant values to make newer constants decoded properly when strace
is built with older kernel headers.
* xlat/netlink_protocols.in: Add default values for constants.
* net.c [!NETLINK_SOCK_DIAG && NETLINK_INET_DIAG]: Remove.
* socketutils.c: Likewise.
As we've got a proper mechanism that parsers can use for storing private
data between entering and exiting stages, all cases of struct tcb.auxstr
abuse should go.
* btrfs.c (btrfs_ioctl): Use set_tcb_priv_ulong and get_tcb_priv_ulong
instead of abusing tcp->auxstr.
* file_handle.c (SYS_FUNC(name_to_handle_at)): Likewise.
* msghdr.c (SYS_FUNC(recvmsg)): Likewise.
* net.c (decode_sockname, SYS_FUNC(recvfrom)): Likewise.
* v4l2.c (print_v4l2_queryctrl): Likewise.
As the msghdr.msg_namelen argument of recvmsg syscall has the same
read-write semantics as the address length argument of recvfrom syscall,
parser of recvmsg syscall needs a similar fix.
* defs.h (fetch_msghdr_namelen): New prototype.
(decode_msghdr): Add "int *" argument.
* msghdr.c (print_msghdr): Likewise. Treat it as a pointer to struct
msghdr.msg_namelen passed to the kernel. Pass to decode_sockaddr
the size of socket address actually returned by the kernel.
Print both user and kernel address lengths when the value changes.
(decode_msghdr, decode_mmsghdr): Add "int *" argument,
forward it to print_msghdr.
(decode_mmsgvec): Update decode_mmsghdr invocation.
(fetch_msghdr_namelen): New function.
* net.c (SYS_FUNC(sendmsg)): Update decode_msghdr invocation.
(SYS_FUNC(recvmsg)): Use fetch_msghdr_namelen on entering to save
struct msghdr.msg_namelen. On exiting, pass the saved value
to decode_msghdr.
* net.c (SYS_FUNC(recvfrom)): Use fetch_socklen. Save the address
length passed to the kernel and print it on error. Do not print more
bytes of the socket address than actually returned by the kernel.
Print both user and kernel address lengths when the returned address
is truncated.
* net.c (decode_sockname): Print both user and kernel address lengths
when the value changes.
* tests/net-y-unix.c (main): Update expected output.
* tests/net-yy-unix.c (main): Likewise.
* tests/net.expected: Likewise.
* net.c (decode_sockname): Print both user and kernel address lengths
when the returned address is truncated.
* tests/sun_path.expected: Update expected output.
* net.c (fetch_socklen): New function.
(decode_sockname): Use it. On entering syscall, decode early
and return RVAL_DECODED when possible. On error, print the address
length passed to the kernel. Do not print more bytes of the socket
address than actually returned by the kernel.
* net.c (do_sockname): Rename to decode_sockname, drop second argument,
do not print sock_type_flags, return RVAL_DECODED on exiting.
(SYS_FUNC(accept), SYS_FUNC(getsockname)): Use decode_sockname instead
of do_sockname, take its return code into account.
(SYS_FUNC(accept4)): Likewise. Print sock_type_flags when
decode_sockname returns RVAL_DECODED.
Introduce a general socket netlink parser which prints the header and
a string for the remaining part of the buffer. It doesn't handle all
the netlink flags and types yet because the parser needs more
information, this will be implemented later.
* net.c (decode_sockbuf): New function.
(SYS_FUNC(send), SYS_FUNC(sendto), SYS_FUNC(recv), SYS_FUNC(recvfrom)):
Use it instead of printstr.
* msghdr.c (print_msghdr): Pass IOV_DECODE_NETLINK to tprint_iov_upto()
for netlink sockets.
* netlink.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* defs.h (decode_netlink, getfdproto): New prototypes.

* util.c (getfdproto): Remove static keyword.
* xlat/netlink_flags.in: New file.
* xlat/netlink_types.in: New file.
* defs.h (msg_flags, socketlayers, decode_msghdr, decode_mmsg):
New prototypes.
* msghdr.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* net.c: Move all msghdr and mmsghdr parsers to msghdr.c.
* fetch_struct_msghdr.c: New file.
* fetch_struct_mmsghdr.c: Likewise.
* Makefile.am (strace_SOURCES): Add them.
* net.c (struct msghdr32, struct mmsghdr32, copy_from_msghdr32,
fetch_msghdr, fetch_mmsghdr): Remove.
(decode_msghdr, dumpiov_in_msghdr): Use fetch_struct_msghdr instead
of fetch_msghdr.
(decode_mmsghdr): Change msg_len argument to use_msg_len.
Use fetch_struct_mmsghdr instead of fetch_mmsghdr.
Return fetch_struct_mmsghdr's return code.
(decode_mmsg): Rename to decode_mmsgvec. Take addr and len arguments.
Do not print vlen and flags. Check decode_mmsghdr's return code.
Print mmsghdr array using square brackets.
(dumpiov_in_mmsghdr): Use fetch_struct_mmsghdr instead of fetch_mmsghdr.
(SYS_FUNC(sendmmsg), SYS_FUNC(recvmmsg)): Use decode_mmsgvec instead

* msghdr.h: New file.
* Makefile.am (strace_SOURCES): Add it.
* net.c: Include it. Move fallback definition of struct mmsghdr there.
* tests/mmsg.c: Include "msghdr.h". Remove fallback definition
of struct mmsghdr.
* net.c (printcmsghdr): Rename to decode_msg_control.

(printmsghdr): Rename to decode_msghdr.
(printmmsghdr): Rename to decode_mmsghdr.
All callers updated.
* net.c (printcmsghdr): Skip control messages of zero length.
Always print "msg_control=" before the control message.
(do_msghdr): Print control message before its length, not after.
* tests/inet-cmsg.c (main): Update expected output.
* tests/scm_rights-fd.test: Likewise.
* net.c (sa_printers): Add minimal address length for each socket family.
(print_sockaddr): Call socket family specific sockaddr printer
only when socket address length is greater or equal
the minimal address length for the socket family.
* xlat/hci_channels.in: New file.
* net.c (print_sockaddr_data_raw): New function.
(print_sockaddr): Use it.
[HAVE_BLUETOOTH_BLUETOOTH_H]: Include "xlat/hci_channels.h".
[HAVE_BLUETOOTH_BLUETOOTH_H] (print_sockaddr_data_bt): Fix printing
sockaddr_hci, sockaddr_sco, sockaddr_rc, and sockaddr_l2 structures.
* net.c (print_sockaddr_data_ipx): Print sockaddr_ipx.sipx_network
using %#08x format. Print elements of sockaddr_ipx.sipx_node array
and sockaddr_ipx.sipx_type using %#02x format.
AF_UNIX abstract socket address specified by sockaddr_un.sun_path
is not a NUL-terminated string.
* net.c (SIZEOF_SA_FAMILY): New macro.
(print_sockaddr_data_un): Use it. Specify actual address length
in print_quoted_string calls. Do not set QUOTE_0_TERMINATED flag
when printing an abstract socket address.
Prior to RFC2553, struct sockaddr_in6 had no sin6_scope_id field.
As the kernel still accepts RFC2133 editions of struct sockaddr_in6,
print sockaddr_in6.sin6_scope_id only when it is specified.
* net.c (SIN6_MIN_LEN): New macro.
(print_sockaddr_data_in6): Print sockaddr_in6.sin6_scope_id only when
socket address length exceeds SIN6_MIN_LEN.
